Opis:
Archaeorthoptera is a high rank insect taxon comprising Orthoptera as well as the extinct orders Titanoptera and Caloneurodea, and several other late Paleozoic groups formerly assigned to polyphyletic Protorthoptera. Synapomorphies defining Archaeorthoptera and some fossil subordinate taxa are exclusively based on wing venation. This study presents a detailed description of two new archaeorthopteran genera and three new species from the Pennsylvanian of the Upper Silesian Coal Basin in Poland. These new taxa provide new insights into the wing venation disparity of this remarkable and insufficiently studied insect group. Omaliella polonica sp. nov. is based on a well preserved forewing, including the wing base, which allows a thorough discussion and comparison with other archaeorthopterans. Surprisingly, it is the first complete wing for this group of related genera (Omaliella, Omalia, Coselia and Paleomastax). Owadpteron dareki gen. et sp. nov. has an unusual arrangement of cubital veins. The marked resemblance of the venation of Owadpteron to that of some members of the gerarid line, such as Nacekomia, supports its placement within the family Geraridae (stemgroup Orthoptera). Finally, the venation of Parapalaeomastax dariuszi gen. et sp. nov. strikingly resembles that of the genus Palaeomastax, differing only in the distally branched media. Discovery of these three new archaeorthopterans from the Upper Silesian Coal Basin fits well with that of closely related taxa known from other deposits in Euramerica, such as Mazon Creek Lagerstätte, Avion in Pas-de-Calais Basin and others. Furthermore, a new re-examination of the earliest archaeorthopteran from the Upper Silesian Coal Basin confirms doubtful assignment of this fragmentary fossil to Archaeorthoptera or even to Pterygota.

paguroid carapace
Opis:
On the basis of carapaces, three new genera and species of symmetrical paguroid anomurans are described. Diogenicheles theodorae, Masticacheles longirostris, and Pilgrimcheles karolinae constitute the oldest known members of the family Parapylochelidae. As noted previously, assemblages from sponge−reefal strata of Oxfordian (Late Jurassic) age in the southern Polish Uplands document an important radiation event amongst paguroids. Compared to the present day, the Parapylochelidae were more diverse during the mid−Mesozoic; they appear to have withdrawn from shallow, reefal waters to deep−water settings from the Late Jurassic onwards. Paguroid faunas from the Oxfordian of Europe already are highly diverse, both morphologically and phylogenetically, and comprise early members of the families Diogenidae, Pylochelidae, and Parapylochelidae. This suggests that the evolutionary history of paguroids started much earlier (i.e., in pre−Jurassic times) than previously assumed. New terms for several typical paguroid carapace regions are introduced and on the basis of carapace morphology and ecological shifts hypotheses on the early speciation of hermit crabs are put forward.

Opis:
New representatives of a stem group Paoliida attributed to family Paoliidae (Insecta: Protoptera) are described from the Upper Carboniferous (Langsettian) sphero−sideritic concretions of the Upper Silesian Coal Basin (USCB) in Poland. Zdenekia silesiensis sp. nov. is based on forewing venation and supplemented by material of isolated hindwing similar in venation pattern. Darekia sanguinea gen. et sp. nov. differs from all other paoliid genera by the presence of a short contact between veins MP and CuA behind the division CuA and CuP. Composition of insect fauna exhibits high abundance of paoliid insects in the early Late Carboniferous ecosystems known also from other European localities such as Hagen Vorhalle in Ruhr Basin (Germany), and South Limbourg (Belgium and the Netherlands). It is the first record of true paoliids from the Polish part of paralic USCB supplementing a single historical record of Stygne roemeri considered as a taxon closely related to Paoliidae. The high abundance of paoliid insects from sphero−sideritic concretions in Sosnowiec and coal deposits previously known from the Czech part of Upper Silesian Coal Basin indicates considerable similarity of both faunas supported as well by their close stratigraphical correlation. Morphology of basal wing parts with remnants of articular sclerites preserved supports neopteran relationships of paoliids. Discovery of the first paoliid immature wing is reported suggesting similar living habitat for larvae and adults.

Opis:
The synziphosurine horseshoe crab Pasternakevia was until now known only from a single specimen. Herein we describe three new specimens from the outcrop close to the type locality of monotypic P. podolica that show several features that were unknown or only assumed in this genus. These characters include: a smooth surface of the carapace; an opisthosoma composed of ten segments, the first one being a microtergite (strongly reduced first opisthosomal segment usually hidden under the carapace), two or three last segments fused into a metasoma, and the telson. Pasternakevia is included in Bunodidae due to a hypertrophied tergite 2, but it is linked to the Pseudoniscidae by the shape of the opisthosoma.

Opis:
A new species of diogenid paguroid, Eopaguropsis nidiaquilae, the earliest known member of the family to date, is recorded from sponge−reefal strata of Oxfordian (Late Jurassic) age in the southern Polish Uplands. Morphological features of the carapace suggest that the family Diogenidae diverged from other paguroid lineages such as the Pylochelidae and Parapaguridae, long before the Oxfordian Stage (161.2–155.7 Ma). The typically deep, V−shaped cervical groove of diogenids most likely was the product of fusion of the branchiocardiac and cervical grooves of their predecessors.

Opis:
Strata with cyanobacterial−sponge buildups of Middle to Late Oxfordian (Late Jurassic) age in the southern Polish Uplands document the earliest known members of the Pylochelidae. Two new Late Jurassic species of “symmetrical” hermit crabs, Ammopylocheles robertboreki and Jurapylocheles iwonae, are described. A new term, the massetic region, is introduced to describe the equivalent in paguroids of the hepatic region in brachyuran carapaces, because in the former, this region does not reflect the position of the liver but rather an attachment zone of the mandibular muscles.
