Paoliida is an insect group of highly controversial composition and equally affinities. Based on comprehensive reinvestigations we propose a new delimitation the order sensu nov. associating families Paoliidae Blattinopsidae basis following main wing venation characters: veins CuA convex CuP concave separating from rather long basal stem Cu; short, more or less distinct, but generally arculus brace (crossvein) between M (more distinct in forewing than hind wing), broad area containing...

Antarctica, with its severe conditions, is poor in terrestrial fauna species. However, an increase human presence together climate change may cause influx of non-native Here we report a significant colonized area one the few known invasive species to date Antarctica. Non-native flies Trichocera maculipennis have been recently observed Admiralty Bay on King George Island, South Shetlands Islands, West 10 years after first record Maritime Antarctica (Maxwell Bay, Island). Its rapid spread...

Sexual conflict - opposite reproductive/genetic interests between sexes can be a significant driver of insect evolution. Scorpionflies (Insecta: Mecoptera) are models in sexual research due to their large variety mating practices, including coercive behaviour and nuptial gift provisioning. However, the role palaeontology studies remains negligible, namely paucity well-preserved fossils. Here, we describe three male scorpionflies from Cretaceous Eocene ambers. The structure notal postnotal...

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

The Late Palaeozoic insect superorder Palaeodictyopterida exhibits a remarkable disparity of larval ecomorphotypes, enabling these animals to occupy diverse ecological niches. widely accepted hypothesis presumed that their immature stages only occupied terrestrial habitats, although authors more than century ago hypothesized they had specializations for amphibious or even aquatic life histories. Here, we show different species semiaquatic in larvae and the supposed retention abdominal...

Both sexes of Burmaculex porczynskii sp. nov. and females Bu. edwardsi harbachi from mid-Cretaceous Burmese amber are described illustrated. A male Borkent & Grimaldi, 2004 is for the first time. Priscoculex Poinar et al., 2019 recognized as a junior synonym Burmaculex, syn. Paleoculicis 2000, represented by Pa. minutus 2000 Upper Cretaceous Canadian amber, placed in subfamily Burmaculicinae.

Abstract During the 2022/2023 austral winter, large swarms of Trichocera (Saltrichocera) maculipennis Meigen, 1818 (Diptera: Trichoceridae), were observed around house roofs in Puerto Williams (Navarino Island, southern Chile, 54° S). In January 2023, presence this species was also confirmed Punta Arenas (53° S), with specimens collected within Chilean Antarctic Institute warehouse facilities. is native to Holarctic region and became established on King George Island (South Shetland Islands,...

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

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