Evolution of Insects in terms of the Implicate and Explicate Orders.
Part IIIb
The Blattaria fauna of the Wettiner Basin
( Wettin and Löbejün near Halle, Germany )
Both fossil insect localities of the Wettiner basin, Wettin and Löbejün, long since known, lie in the former DDR, about 20 km N.N.W. of the city of Halle, Germany. They geologically belong to the Ottweiler Stufe, Upper upper-Carboniferous. The Wettiner basin is, like the Saar basin, a limnic inland depression. As to the fossil Blattida, also here the majority belongs to the family Archimylacridae. The geological and ecological status is largely similar to that of the Saar basin (see previous two documents).
The literature in which the fossil Blattida of the Wettin basin are described :
- HANDLIRSCH, A., Die fossilen Insekten ud die Phylogenie der rezenten Formen, 1906-8.
- SCHLECHTENDAL, D. v., Untersuchung über die karbonischen Insekten und Spinnen von Wettin, unter Berücksichtigung verwanter Faunen. Erster Teil : Revision der Originale von Germar, Giebel und Goldenberg. 1912 [appeared in 1913, in NOVA ACTA. Abh. der Kaiserl. Leop.-Carol. Deutschen Akademie der Naturforscher. Band XCVIII. Nr.1.]
We will now list and depict the sufficiently well-preserved fossil Blattida of the Wettiner basin (localities : Wettin, Löbejün) :

Frame 1 :
Anthracoblattina spectabilis GOLDENBERG
Family Archimylacridae. Length of tegmen (Fig.9a) about 45 mm.
Locality : Löbejün in Sachsen.
Stratum : Ottweiler Stufe, upper Upper-Carboniferous.
Figure 9a (upper image) [including Fig. 9c (second image, detail of wing-base)] is the counterpart of what is depicted in Figure 9b (bottom image of frame 1).
In this bottom image (of frame 1) a, c, and b depict the archedictyon of the areas a, c, and b in Figure 9b.
The arrow in Fig. 9b indicates the location where SCHLECHTENDAL has forgotten to draw a simple vein (5th branching of CuA).
(Figure 9a, 9b, 9c after SCHLECHTENDAL, 1912, Tab.VI, fig. 9abc)
Fig. 9a is the same specimen as the one depicted in Fig. 4 in Taf.XXI in HANDLIRSCH, 1906. ( Frame 2 ).
Fig. 9b is the same specimen as the one depicted in Fig. 11 in Taf.XIX in HANDLIRSCH, 1906. ( Frame 3 ).

The figures corresponding to the numbers 6, 12, 19, 24, 31, and 34 in Tafel XXII in HANDLIRSCH, 1906, are not reproduced here because the figures are distorted as a result of bookbinding.
I do, however, give the names of the described fossils corresponding with these numbers :

In what comes next we will continue to depict fossil Blattida from Wettin and surroundings, as they have been drawn in Tafel XXIII of HANDLIRSCH's "Die fossilen Insekten of 1906.
The following of these drawings, however, are, as a result of bookbinding, too defective to be reproduced here : fig. 3, 8, 13, 17, 26, and 31. They will be listed.
The next drawings in HANDLIRSCH I will not consider at all, because the fossils are too fragmentary : fig. 36, 38, 42, 40, 39, 41, 37, and 44.
We will now list the above Blattida species.

This form, apparently, had still to be named by SCHLECHTENDAL. At the time, the latter was still investigating the Wettin-Löbejün fossil fauna (insects and spiders), and had sent original specimens to HANDLIRSCH.

Figure 28 in HANDLIRSCH's Tafel XXVI, is about too fragmentary a fossil for us to deal with.
Frame 83 :
![](scriptie_1544_38.jpg)
Comments
HANDLIRSCH, 1906, p.255, indicates as locality (where the fossil was found) "Wettin and Löbejün in Sachsen". In addition, he notes that the (rock-) impression depicted in fig. 39 (Taf.XXVI) (2nd image in frame 83) is very similar to the specimen of GOLDENBERG : but this is the counterpart of the impression depicted in Fig. 38 (1st image in frame 83), both found in Löbejün. See SCHLECHTENDAL, 1912, p.79 : Figure 8 in GOLDENBERG 1869 is : Syscioblatta Dohrni SCUDDER. Locality : according to the label pasted on both counterparts : "Insect aus dem Schrambergen des Oberflötzes Loebejün."
The original (specimen) of GOLDENBERG [In the script of Tafel XXVI HANDLIRSCH mistakenly notes with respect to figure 38 : GERMAR's original. See the text on page 255 in HANDLIRSCH himself, and SCHLECHTENDAL, 1912, p.79.] :
Kgl. mineralog. Museum Dresden. Hochdruck Blattina euglyptica GERMAR Nr.1.
Counterpart of it : Kgl. geolog. Institut Breslau. Hohldruck (Runge 1867) without pronotum [And thus corresponding to Fig.39 of Tafel XXVI in HANDLIRSCH, and reproduced here as second image of frame 83.]
The counterpart depicted in Tafel XXVI, fig. 38 (and reproduced here as first image of frame 83) was determined by GOLDENBERG as belonging to the earlier described species Blattina euglyptica GERMAR.
This piece (together with its counterpart of the Kgl. geolog. Inst. Breslau) is later determined as to belong to the species Syscioblatta Dohrni SCUDDER.
The pronotum, in fig.38 of Taf. XXVI in HANDLIRSCH (first image, frame 83), does not lie in its natural position, but transversely with its front end to the right (i.e. in the figure upwards).
See also the drawings made by SCHLECHTENDAL, 1912, as they are reproduced here as the third image in frame 83 :

The Blattida incertae sedis (Blattoidea incertae sedis in HANDLIRSCH, 1906, pp.292) will not be dealt with here.
These, then, were all the Blattida from Wettin (near the town of Halle, Germany) and surroundings, as far as recorded up to 1912.
The fossil (upper upper Carboniferous) blattida fauna of this locality comprises four well-represented families, viz., Archimylacridae, Spiloblattinidae, Mylacridae, and Poroblattinidae, of which the latter two consist of rather small forms as compared to the first two.
Of the family Archimylaridae many species have been described from Wettin, especially of the genus Phyloblatta. Whether they, based on tegmina only, are genuine species is not so certain. Let us quote TILLYARD in Kansas Permian Insects, part 20 (I), The Cockroaches, or Order Blattaria, p.185-7, in American Journal of Science, 34, of the year 1937 :
Owing to the well-known variability of the venation in the wings of Cockroaches, it is extremely difficult to define the fossil species. Probably far more species have been named, especially in genera like Phyloblatta, than are reasonably justified. On a number of occasions I have drawn the venations of the left and right forewings of recent Cockroaches and have never found the branching of the main veins in the two wings the same. This variability has always to be borne in mind when attempting to fix the limits of fossil species, and I think it is preferable to err, where possible, on the side of broadness rather than of narrowness.
Nevertheless, we may safely say that the Wettin fossil blattida fauna has yielded more than, say, sixty, species. And this is significant enough. It shows that conditions there (and then) were very fit to sustain a rich Blattida fauna.
Evaluation and theoretical conclusion as a result of the composition of the palaeozoic Blattida fauna of Wettin and surroundings.
Because (1) the Blattida are poor flyers (their wings principally assist in jumping), (2) they have little ecological adaptability, and (3) [because] there is good reason to hold that the four basins (Saar, Wettin, Dunkard, Kuznets) were (at the time) more or less isolated spatially (like 'islands' in the landscape), geographically widely apart from each other, and, moreover, [because there is good reason to hold that] the large geographical regions separating them are ecologically unfit for them (to inhabit or to pass through) (dry and cold elevated regions, inland seas), -- it is clear that blattids (and also their egg-cases and larvae) cannot have spread by passive transport or active migration from one basin to another. Therefore it is also clear that the blattid families cannot have (each for themselves) evolved from a single region of origin (and then from there allegedly having migrated, while remaining morphologically largely the same as to their tegmina at least, into all directions). Each family must have originated -- in the Carboniferous -- polytopously (i.e. originated at more than one place) and therefore polyphyletically (i.e. having originated from different, independent stocks).
The evolution, which in our theory is the successive appearance of different forms (species) in the Explicate Order, is supposed by us to reflect, in an approximate way, the course of noëtic construction in the Implicate Order, the construction that is, of the overall strategies (morphologically as well as behaviorally taken) of the successively appearing species. This reflection is not necessarily expressed by the actual consecutive order of appearance in the Explicate Order, but only insofar as we can detect in the actually existing, or having existed, species derivational relations formally (and thus not necessarily temporally or genealogically) connecting these species. And such relations may be expressed in "polydiagrams" (for these, see the Section "Polyphyletic development of strategy-contents and their noëtic construction in the Implicate Order" in " Theoretic Intermezzo" after Part VIII (Heteropterygia)). In fossil Blattida we can follow (if at all) this noëtic construction only as to the venation of the forewings or tegmina. Because of the apparent individual variation in the venation, we should focus not so much on the precise number of branches and forks, but on the respective areas supported by the main venational systems, Sc, R, M, CuA, and perhaps on the structure of the clavus (including CuP or vena dividens).
The general tendency in the 'evolution' of the venation of the tegmina in palaeozoic Blattida is that the subcostal area, being initially moderate in extension with dichotomically split branches of Sc, is extending (i.e. lengthening) first, while the branches of it together become arranged into a more or less pectinate series. After this, the area of Sc is contracted again, and the anterior branches of the Radius (R) functionally replace those of Sc. We see this not until the Mesozoic. The Medial area may increase, or the CuA system may increase its number of branches. In the Poroblattinidae, however, the CuA system is strongly contracted. The anal veins may eventually end up, not in the margin of the clavus anymore, but in the vena dividens (CuP).
In the family Mylacridae the venation of the tegmen becomes more or less symmetrical with respect to the median axis of the wing. Further, the size of the tegmen in especially the Mylacridae and Poroblattinidae becomes quite small, in the order of a mere 10 mm long.
In all this, we have to find out whether all these tendencies in the venation in palaeozoic Blattida have occurred independently in a more or less large number of parallel lines, or not. As to the differences between (1) the more primitive members of the family Archimylacridae (with a radial [i.e. more or less fan-like] and dichotomical branching of Subcosta), (2) all the forms centering around Phyloblatta (moderately long Sc, with its branches comb-shaped arranged) and grading into the Spiloblattinidae (narrower wing with subparallel anterior and posterior wing borders, and with weaker archedictyon), (3) Mylacridae (symmetrical tegmen), and (4) Poroblattinidae (contracted CuA), -- we indeed see four (or perhaps five) different venational types of Blattida tegmina. And we suppose that derivational lines or series, that can be set up between these types or differences, reflect in some way the noëtic construction of strategies (in the Implicate Order) insofar as the venation of tegmina (being part of such a strategy) is concerned.
But these are the only genuine (i.e. constant) morphological differences (allowing to recognize types) occurring among palaeozoic Blattida tegmina. And there might be detectable, not one, but a whole bundle of parallel derivational lines or series, each one of them formally connecting these types, one with the other. But, in detecting such a bundle we may have been misled by the phenomenon of individual variation in the venation, and this could mean that there is in fact only one single overall derivational line or series seen in the Explicate Order reflecting the noëtic construction in the Implicate Order (as expressed in a "polydiagram" [see below] ). If so, it is to be expected that wherever we find forms that allegedly cannot be placed in this one derivational line as a result of apparent specialization-crossing, and thus should be considered to be members of another line parallel with the first one, the venational differences, causing the alleged specialization-crossing all fall within the range of mere individual variation, not representing different species at all, but individual variants of some species of the first derivational line. So it might be that in palaeozoic Blattida there is only one single derivational line -- as to the wing-venation of tegmina -- (if there is such a line at all !) reflecting the noëtic construction of every palaeozoic species of Blattida. That is to say, there is, it is true, a separate noëtic construction course for each species, but these courses only differ from one another in one or more of their final stages. See next drawing, schematically expressing a polydiagram.
![](poly_91.gif)
Diagram above : Ascending noëtic construction lines (bold vertical black lines), each one leading to a different species. As to their structure (construction-stages) these lines are reflected by derivational lines -- in fact one derivational line -- in the Explicate Order (horizontal thin black lines, each of them being a part of the same overall derivational line), and differ from each other only in their terminal parts (these differences symbolized by their different heights).
There must, of course, exist a great many of such vertical construction lines (because there were many palaeozoic Blattida species), and when we, in such a completed diagram, go from left to right we will pass from one venational type to the next. And there are four or five such types on the basis of the mentioned venational differences and tendencies.
In order to fully appreciate the exposition of the noëtic construction of blattida tegmina (and of strategies in general) with the help of so-called "polydiagrams", the reader may consult the two-document " Theoretic Intermezzo" which is inserted into the present series of documents after part VIII (Heteropterygia). For "polydiagrams" in particular the reader should, in that same " Theoretic Intermezzo", consult the Section Polyphyletic development of strategy-contents and their noëtic construction in the Implicate Order (to be found at about the last sixth of the (first) document).
As we shall see in the next document, we can formally pass through these venational types in roughly three (parallel) ways, which means that at least three (instead of only one) derivational lines can be detected, formally connecting these types with one another in the Explicate Order, and, as we shall also see in the next document, each segment of such a (horizontal) derivational line corresponds to a (vertical) noëtic construction line in the Implicate Order, where "corresponds" means that the construction-stages in the noëtic lines are more or less reflected in the derivational lines formally connecting the venational types.
The great majority of Blattida tegmina are of, or stand close to, the phyloblatta-type including even the lower Permian forms of Kansas (Permoblattina, and Pycnoblattina) which were assessed by TILLYARD (1937) to belong to the family Spiloblattinidae (and thus to the spiloblattinid type).
So what is indeed the most conspicuous feature of the Blattida of the Saar, Wettin, Dunkard, and Kuznets basins, is their great venational similarity. All the many different 'species' of the genus Phyloblatta are based on minor venational details, of which many may, however, accounted for by individual variation. Indeed, the various taxa of fossil Blattida, distinguished by authors, in the faunae of these basins (and other localities) may simply be no more than mere parataxonomical categories instead of true genealogical or typological taxa, because in virtually all cases all we have are tegmina or fragments of them.
So it is indeed the existing great similarity, or, often, even (qualitative) identity, of forms, that is conspicuous when we compare Saar-blattida or Wettin-blattida with either Dunkard- or Kuznets-blattida, or with any other palaeozoic blattida for that matter. And it is this similarity between forms widely separated from each other by ecological and geographical barriers, that convinces us of their polyphyletic origin. And the very fact that such an origin is possible at all, makes polyphyletic origin of all insects, and of all organisms for that matter, at least less problematic to suppose.
For the phyloblatta-type, at least, we may say that it will appear everwhere where existing ecological existential conditions are such as to demand a strategy of some particular type (venationally expressed in the phyloblatta-type), which [strategy-type], apparently, necessarily implies the phyloblatta-type of tegmen, either by functional reasons, or as a result of noëtic 'constructionalist' constraints (in the latter case such tegmina, as to their phyloblatta-venation and shape, are necessary by-products or concurrent structures in the noëtic construction of the strategy-content). And such a particular strategy-type, and thus with it the phyloblatta venational type, independently appears in the Explicate Order wherever, in this Order, the corresponding ecological existentional conditions are met.
"Blattopterygia" is (or, at least, is meant to be) a functional wing-type, which is confined to the Order Blattida only, and splits up into the four above mentioned morphological (i.e. venational) types, or, let us say, subtypes : archaic archimylacrid subtype, phyloblatta subtype, poroblattinid subtype and mylacrid subtype. Maybe we could add the spiloblattinid subtype (grading off from the phyloblatta subtype). The species possessing them appear where appropriate conditions prevail.
Blattopterygia, considered in itself, as part of a strategy, is more or less self-contained and homogeneous. Therefore, we cannot say anything significant of its noëtic creation from (a likeness of) some other type or types, neither (can we say anything particularly significant with any certainty) of the noëtic construction of each of the mentioned morphological subtypes within blattopterygia, and even if we can, it is purely hypothetically so (see next document) : Indeed, we may formally connect these venational subtypes with each other and so account for the origin of some of them from the other subtypes, but the direction of venational derivation, if these subtypes are derivationally connected with one another at all, is not clear (for instance, is the Subcostal area contracting or lengthening ?) and is (next document) determined more or less subjectively. All this does not, however, diminish the heuristic and methodical value of the blattida-polydiagrams in the next document.
And also precisely whereto (at least a likeness of) blattopterygia has led, if to anything at all, we cannot say, except, perhaps, that it has led to the wing-apparatus of termites (Mastotermes).
Polyphyletic origin of Blattopterygia, because this wing-type is present in Blattida only, means that the various blattid groups, and perhaps even all the blattid species, appeared independently of each other in the Explicate Order. And this further means that it is only in their noëtic construction, in the Implicate Order, that they are connected with one another in a certain way : Each noëtic ascending line (ending up in some blattid strategy-content, and here only considered insofar as tegminal venation is concerned), is a succession of noëtic construction stages, which (succession) is more or less reflected by the venational differences between the above mentioned morphological subtypes of Blattopterygia, or at least [such construction stages] do involve the venational structures of some of them.
We shall work this out in the next document -- before continuing with the other two basins [Dunkard and Kuznets] having supported palaeozoic Blattida -- in the form of polydiagrams, although realizing that much uncertainty is involed here, as a result of the (absolute) fragmentary nature of fossils, and as a result of the great individual venational variability that can be assumed (also) in the palaeozoic Blattida.
With this we conclude the exposition of the blattarian fauna of Wettin. In the next-next document we will describe the Blattarian fauna of the Lower Permian of the Dunkard Basin, S.E. United States.
