A case of biodiversity overestimation in the Balkan Belgrandiella A. J. Wagner, 1927 (Caenogastropoda: Hydrobiidae): molecular divergence not paralleled by high morphological variation

Belgrandiella A. J. Wagner, 1927 is a genus comprising minute snails with conic or turriform shells that are facultative stygobionts, inhabiting subterranean waters and springs. Few specimens or even empty shells of this taxon can be found, so the taxonomy is based mostly on the shell morphology and geographic distribution. Anatomy is known for a few taxa, and its usefulness is restricted. This, coupled with a popular idea that isolation is the first factor shaping divergence and speciation of the spring/cave fauna, resulted in dozens of nominal species of Belgrandiella, known from shells at a given locality. Herein we present shells, anatomy and four molecular markers (nuclear H3, 18S and 28S and mitochondrial cytochrome oxidase subunit I) in Belgrandiella from 16 localities in Slovenia, northern Croatia, and Bosnia and Herzegovina. Five sites are type localities of Boleana umbilicata, Belgrandiella kusceri, Belgrandiella krupensis, Belgrandiella zermanica and Belgrandiella robusta, respectively. Considering the shell and geographic distribution, we have determined B. cf. robusta Belgrandiella cf. croatica, Belgrandiella cf. fontinalis, Belgrandiella cf. kuesteri, Belgrandiella cf. pageti and Belgrandiella cf. koprivnensis The shells of all, as well as penes and female reproductive organs of two putative, species have been illustrated. Molecular analysis indicates four distinct clades, most probably of species rank for B. kusceri, B. cf. kuesteri, B. cf. fontinalis and B. cf. koprivnensis. Four nominal species (B. krupensis, B. robusta, B. umbilicata and B. zermanica) and one genus (Boleana) must be synonymised with Belgrandiella kusceri, and there are no more than four valid, biological species in the studied Belgrandiella. The molecular divergence is completely unmirrored by high morphological variability. Hence the level of endemism is markedly overestimated in these snails.     

Revision of the subfamily Cardiochilinae Ashmead, 1900 (Hymenoptera: Braconidae) in Egypt,with new records and a new species

In the present study, the subfamily Cardiochilinae (Hymenoptera: Braconidae) is revised. This study is based on specimens deposited in Egyptian repositories. Many of them were collected during Priesner’s trips to Gebel Elba (extreme south-west of Egypt). The subfamily Cardiochilinae is represented in Egypt by 11 species in three genera, Bohayella Belokobylskij, 1987 (one species), Cardiochiles Nees, 1819 (three species) and Schoenlandella Cameron, 1905 (seven species). The cardiochiline species C. pseudofallax Telenga, 1955 and S. deserta (Telenga, 1955) are recorded here as new records in the fauna of Egypt. The females of previously known male C. weidholzi Fischer, 1958, S. acrenulata (Fischer, 1958) and S. obscuriceps (Fischer, 1958) as well as the male of the previously known female S. glabra (Fischer, 1958) are described. Schoenlandella pseudoglabra sp. nov. is also described and illustrated.

Integrative taxonomy of the gymnophthalmid lizard Neusticurus rudis Boulenger, 1900 identifies a new species in the eastern Pantepui region,north-eastern South America

ABSTRACT

The gymnophthalmid lizard genus Neusticurus Duméril and Bibron, 1839 currently contains six described species. One of them, Neusticurus rudis Boulenger, 1900 has a long history of taxonomic confusion, and uncertainty remains about the number of species involved under that name, especially in the Pantepui region. Our molecular phylogenetic (concatenation and species tree) and morphological (morphometrics, external and hemipenial morphology) analyses confirm Neusticurus rudis as a species complex with several candidate species in the eastern Pantepui region. Neusticurus rudis is here redescribed based on the re-examination of the holotype and 10 specimens from the vicinity of the type locality (ca. 15 km airline) in Guyana. The geographic distribution of N. rudis sensu stricto is restricted to east of the Venezuelan Gran Sabana, extending from the slopes of Mount Roraima in Venezuela through the slopes of Maringma-tepui and Wayalayeng to Mount Ayanganna in Guyana, between 678 and 1500 m elevation. Populations tentatively assigned to N. rudis also occur from Mount Wokomung in the Pakaraima Mountains of Guyana to the Iwokrama Forest Reserve in Guyana, between 159 and 1234 m elevation. A new Neusticurus species is described from the uplands and highlands of the eastern Pantepui region, west of the Venezuelan Gran Sabana in Brazil and Venezuela, between 900 and 2200 m elevation. Populations provisionally assigned to the new species were also found from the La Escalera region to Chivatón, the summit of Abakapá-tepui and the slopes and summit of Auyán-tepui, Venezuela, between 1100 and 2203 m elevation. Our results suggest the Gran Sabana as a possible recent biogeographical barrier for the genus in the region and indicate that tepui-summit Neusticurus populations derive from uplands populations that shifted their habitat preference.

A new landhopper species of Myanmarorchestia (Crustacea: Amphipoda: Talitridae) from Yunnan,China

A new landhopper talitrid, Myanmarorchestia nunomurai Nakano and Morino, sp. nov., from Yunnan Province, China is described. Since species of Myanmarorchestia were known only from Mt. Victoria of the Arakan Mountains of Myanmar, this is the first record of the genus from China. Myanmarorchestia nunomurai is characterised by its coxal gills on gnathopod 2 to pereopod 6 without filamentous projections while the other congeners from Myanmar possess some/all of the coxal gills with filamentous projections. Additionally, M. nunomurai can be diagnosed by the sexually dimorphic uropod 2, of which the outer ramus bears a robust seta on the midlateral surface and a few rows of small teeth on the middle to distodorsal surface.

Albertine Rift Valley endemics: three new species of freshwater crabs (Brachyura: Potamoidea: Potamonautidae) from Uganda,the Democratic Republic of the Congo,and Rwanda

Three new species of potamonautid freshwater crabs are described from the Albertine Rift Valley, Eastern Africa. One of the new species is from Bwindi Impenetrable Forest in Uganda, the second is from Lake Kivu in Rwanda, and the third is from the Rwenzori Mountains in the Democratic Republic of the Congo and Uganda. Diagnoses, illustrations and distribution maps are provided for these taxa, and they are compared to similar species from Uganda and elsewhere in East Africa.

Earthworms (Annelida: Oligochaeta) from islands of Kien Hai District,Kien Giang Province,Vietnam, with descriptions of two new species and one subspecies

An earthworm inventory was conducted on three islands (Hon Tre, Lai Son and An Son) in the southernmost part of Vietnam. A total of 13 species and subspecies belonging to four genera and two families were collected from 49 sampling sites. The genus Metaphire Sims & Easton, 1972 is dominant with six species and subspecies, Metaphire anomala (Michaelsen, 1907), Metaphire bahli (Gates, 1945), Metaphire houlleti (Perrier, 1872), Metaphire mangophila (Nguyen, 2011), Metaphire kiengiangensis Nguyen & Trinh, 2015, Metaphire peguana laisonensis subsp. nov. Two new species, Polypheretima dorsotheca sp. anov. and Polypheretima insularis sp. nov., and a new subspecies Metaphire peguana laisonensis subsp. nov. are described. Additionally, Amynthas alteradamae (Michaelsen, 1934) and Amynthas tertiadamae (Michaelsen, 1934) are re-described based on fresh material. An identification key to species is also provided.
