Revisiting Betsch & Weiner (Collembola, Symphypleona, Sminthuridae): new species, updated diagnoses, and a key.

Betsch & Weiner is a genus of Sphyrothecinae (Sminthuridae) similar to Börner, with 13 nominal species. Most descriptions of taxa lack valuable data in face of the current taxonomy of Symphypleona. In this study the previously described species of the genus were surveyed, aiming to provide updated diagnoses for them.

Investigation on the true identity of Stach, 1929 (Collembola, Entomobryidae) with the description of a new species.

The present paper gives a detailed and illustrated redescription of Stach, 1929, and the description of a new species collected from open sand steppe habitat in Hungary. Based on the colour pattern, Winkler, Flórián & Dányi, is close to Stach, 1963 but differs from it by the morphology of the labral papillae and the dorsal macrochaetotaxy of the head, Th II, and Abd II-IV. The new species is also characterised by dark ventral body colouration in adult specimens.

A new species of the genus Amyot et Serville, 1843 (Heteroptera, Reduviidae), with data on its chromosome complement.

A new species, (Heteroptera: Reduviidae: Harpactorinae: Rhaphidosomatini), is described from the Dry Zone of Myanmar. It is the fifth species of Amyot et Serville, 1843, known from the Oriental Region, and the first record of the genus for Myanmar and Indochina. The structure of the external and internal terminalia of the male and female is described and illustrated in detail.

Two new species of Bagnall, 1948 (Collembola, Onychiuridae) from Romania and an updated key to the genus.

Two new species of the genus from Romania, . and , are described and illustrated. has a postantennal organ (PAO) with 13-15 simple vesicles, abdominal terga I-III with subequal setae p and p, abdominal tergum V granular area with 3+3 distinct, long macrosetae, and .

First records of 31 species of butterflies and moths (Lepidoptera) in Cameroon, with remarks on their elevational ranges.

Background: The biodiversity of West and Central Africa is understudied, including butterflies and moths (Lepidoptera). Cameroon, through its position in between few biogeographic regions and diversity of habitats, is an important hotspot of lepidopteran diversity. However, the country also ranks low when it comes to local biodiversity knowledge.

sp. nov. (Protura, Acerentomidae, Nipponentominae) from the Arctic region, with a key to species of the genus.

A new species of was collected in the most northern part of the Palearctic, inside the Arctic Circle. In possessing seta on tergite VII and sternites VI-VII and a very long foretarsal sensillum , is more similar to species than to the other species distributed in southern Siberia and northern China. The new species differs from nearly all other members of Nipponentominae in possessing five anterior setae on tergite VII and in the presence of posterolateral pores on tergite I, as in members of (Hesperentomidae).

Variation in the number of testicular follicles and ovarioles among 18 lacewing species of the families Myrmeleontidae, Ascalaphidae, and Nemopteridae (Insecta, Neuroptera, Myrmeleontiformia).

The representatives of the lacewing families Myrmeleontidae, Ascalaphidae, and Nemopteridae (the suborder Myrmeleontiformia) were studied with reference to the number of testicular follicles in males and the number of ovarioles in females. We have found that the number of follicles is highly variable, at least in the first two families. In the comparatively more fully explored family Myrmeleontidae, the species studied have three to several hundred follicles per testis, the dominant values being six and five.

A new species of Berlese, 1908 (Protura, Acerentomata, Acerentomidae) from Bulgaria with a revised key to the group.

A new species, ., belonging to the group, is described from Bulgaria. This species is characterized by long foretarsal sensilla and , the posterior position of foretarsal seta δ, the presence of seta on abdominal tergites II-VII and seta on abdominal tergite VII, possession of eight anterior setae on abdominal tergite VII and composed pores on sternite VI.

species from mushrooms in China (Collembola, Hypogastruridae).

Four species of the genus living on mushrooms are reported from China, including a new species, Weiner & Sun, , which is described from alpine mushrooms. The new species belongs to the group of species with a dorsal chaetotaxy of type B and differs from the other species in a combination of characters. is distinguished by its small body size (maximum length 1.

New insights into the karyotype evolution of the genus (Orthoptera, Tettigoniinae, Gampsocleidini).

Five species belonging to the genus Fieber, 1852 were analyzed using fluorescence hybridization (FISH) with 18S rDNA and telomeric probes, as well as C-banding, DAPI/CMA staining and silver impregnation. The studied species showed two distinct karyotypes, with 2n = 31 (male) and 2n = 23 (male) chromosomes. The drastic reduction in chromosome number observed in the latter case suggests multiple translocations and fusions as the main responsible that occurred during chromosome evolution.
