During the investigation of cyanobacterial diversity in Božana Cave, which is situated in a limestone region in western Serbia, a new species of cyanobacterium belonging to the genus Nephrococcus was found. So far, there are only three records of the genus Nephrococcus in the whole world (recorded in China and Nepal), which was reviewed and is presented in this study. Detailed morphology of the examined cyanobacterium was documented by digital photography and drawings using light and confocal laser microscopy. Ecology (temperature, relative humidity and light intensity) and biofilm parameters (chlorophyll-a, the water content and the content of organic/inorganic matter in the biofilm) were also measured, and the associated taxa described. Detailed morphological characteristics that indicated the differences between this species from those already known, allowed us to describe this cyanobacterium as a new species, Nephrococcus serbicus. This is the first record of the genus Nephrococcus in the territory of Europe.

AbstractThe genus Hirsuticyclus Neubauer, Xing & Jochum, 2019 was the first record of an exceptionally preserved land snail with dense periostracal hairs from mid-Cretaceous Kachin (Burmese) amber. Here we document four newly-discovered shells from Kachin amber, one belonging to the type species Hirsuticyclus electrum Neubauer, Xing & Jochum, 2019 and the remaining three shells belonging to a new species, Hirsuticyclus canaliculatus sp. nov. Well-preserved morphological characteristics of these two species could be clearly demonstrated under light microscopy combined with modern micro-CT scans with computer 3D reconstructions. Our new material of the type species amends the generic diagnosis based on a better-preserved shell including the peristome and operculum. The new species shows distinctive shell characteristics such as numerous spiral keels and a flaring, folded peristome interrupted by two canals. These excellently preserved fossils contribute to our understanding of the morphological diversity and evolution of these ancient members of cyclophoroids.

Both sexes of Parastethynium maxwelli (Girault), a parasitoid of Zophiuma lobulata Ghauri eggs on coconut and oil palm in Papua New Guinea, are described and illustrated. The second known species in the genus Parastethynium, P. hirsutum Huber sp. n., from Indonesia (Sulawesi) is also described. The latter represents the first record from the Oriental region. The basic biology of P. maxwelli is presented. Mean progeny produced per female was 57 with a female proportion of 0.59. Mean egg to adult development time was 11 days, at 24.5 o C−29.7 o C and 72−93% relative humidity. Survival time of females and males fed on honey and water was longer compared to males and differed significantly with those provided with water only or nothing at all.

Neurosystasis Satchell is newly recorded in Mexico by means of the description of a new species. Specimens captured in a tropical deciduous forest in southern Puebla, central Mexico, were examined and determined as a species new to science. The male and female are described based on morphological characteristics. Neurosystasis longistylis sp. nov. is similar in appearance to Neurosystasis saltenia (Omad, Mangudo & Gleiser, 2015), but is readily distinguished based on characters of the head, wing, and male genitalia. In both species, R2+3 is attached to vein R4, the wing membrane is infuscate with dark spots on vein apices, and lacks sensory organs near the apex of Sc, characters not present in other species of Neurosystasis, and for that reasons we proposed the recovery of Chuspilepia from its synonym and validate it as a subgenus of Neurosystasis to include both continental species.

Pteroptyx maipo sp. nov. is the first record of the genus Pteroptyx Olivier from mainland China and Hong Kong and represents the most northerly record for this genus. The description includes all life stages: egg, larva, pupa and adult, and covers special structures such as the female bursa plates and male copulatory clamp. Details of habitat, male courtship flash patterns and male-female courtship behaviour are described. This species is the second in the genus Pteroptyx found to use a copulatory clamp, which functions to wedge the mating pair together. A complete clamp however does not appear necessary for successful insemination. Bursa plates hold the spermatophore partially projecting into a spermatophore-digesting gland. Other functions for the plates are investigated and discussed. The deflexed elytral apex appears after eclosion in the adult male. Mechanisms for the loss of ventrite 8 in the male abdomen are explored. A list of the 30 Pteroptyx species recognised here, with habitats, some morphological characteristics and a key to species of the Oriental Pteroptyx are provided.

The first record of the previous monotypic genus Tethytimea and the description of a new species from cryptic habitats of Gulf of Mexico are presented. Tethytimea carmelita sp. nov., is a red orange cushion shaped sponge (about 5 mm thick) with a tuberculate to granular surface. The spicular complement is formed by tylostyles (200–1120 µm length), smooth spheres (12.5–55 µm in diameter); megasters-spheroxyasters (12.5–90 µm in diameter); and micrasters in two categories: oxy-strongylasters (12.5–27.5 µm in diameter) and spherotylasters (2.5–25 µm in diameter). The new species differs from the only species known T. tylota (Hentschel, 1912) mainly by differences in the size and shape of spicules. T. tylota possesses tylostyles in two size categories; megasters include giant oxyspherasters up 250 µm and micrasters in a single category. Additionally, to the morphological characteristics, we integrated partial sequences of a large sub-unit ribosomal 28S rDNA gene region (D1–D2 domains), in order to establish the molecular taxonomic position of our new species (and genus). Tree topologies (Maximum Likelihood and Bayesian Inference) were congruent in phylogenetic hypothesis, retrieving the Order Tethyida as monophyletic. In this clade, the family Timeidae was separated from the other families Tethyidae + Hemiastrellidae. Inside this latter group and according to the taxonomic hypothesis based on morphology, Tethytimea carmelita sp. nov. was included in Tethyidae clade, together with a sequence of Tethya sp. (AY626300), forming a sister group with representatives of genera Xenospongia and Thectitethya. Our new species constitutes the second valid known species for the genus Tethytimea and the first record of genus for the Atlantic Ocean.

Scrophularia vernalis (Scrophulariaceae) is recorded from Artvin province (NE of Turkey), which constitutes its first record for the Turkish flora. In this study, an expanded morphological description, geographical distribution, habitat characteristics and ecological features of the species are shown with illustrative figures. Moreover, the pollen and seed morphological characteristics of S. vernalis are determined for the first time and compared with the closely related species S. chrysantha. With this species, the total number of the Scrophularia taxa in Turkey is now 77.

Gastrotricha is a cosmopolitan phylum of aquatic and semi-aquatic invertebrates that comprises about 820 described species. Current knowledge regarding freshwater gastrotrichs inhabiting caves is extremely poor and there are no extant data regarding Gastrotricha from Montenegro. We describe a new species from Obodska Cave, which is also the first record of a gastrotrich from this region. Due to its unusual habitat and morphological characteristics, this species may be important when considering the evolution and dispersion routes of Chaetonotidae Gosse, 1864 (sensu Leasi & Todaro 2008). We provide morphometric, molecular and phylogenetic data for the new species, together with photomicrographs and drawings.

A new species of Charinus Simon, 1892 is described from French Guyana, raising the number of species in the genus to48 (27 for the Neotropical region and 19 for South America). Charinus bromeliaea sp. n. is distinguished from the otherspecies in the genus by morphological characteristics and unique ecology. Adapted to live in Achmea bromeliads on gran-ite inselbergs, this species is an interesting addition to the wide range of habitats Charinus species are found in. This is also the first record of the genus from French Guyana and this record extends the geographic distribution of the genus.
