A new species of free-living nematode Monhystera tibetica sp. nov. from a thermal spring in the Garuda Valley at an altitude of 4249 m in Western Tibet is described. The general morphology corresponds to the generic diagnosis. The cephalic setae are very short. In the lower part of the stoma there is a small denticle. The amphid of males is situated over the level of the denticle. The distance from the edge of the head to the denticle is about 6 μm. The amphid of females is situated above the denticle. The esophagus is dilated at the base, pseudobulbus width is 22 μm. Males have numerous precloacal supplements. From the geographically close species of M. curvicaudata Tsalolikhin, 1915 the new species is distinguished by body size, amphid position, position of the vulva and the presence of the stomal denticle. From M. wangi Wu et Hoeppli, 1929 the new species differs by the amphid position and the presence of the stromal denticle. From M. shibrui Eyualem et Coomans, 1996 the new species differs in body size and length of spicules. The taxonomic status of the species with one and two denticles is discussed. The replacement of the name Tridentulus with Tridentula is no longer relevant. The validity of the name Tridentulus Eyualem et Coomans, 1995 is maintained.

The genus Setoxylobates (Oribatida, Haplozetidae) is recorded in Taiwan for the first time; one new species of this genus is described based on adults from soil of mountain tea farm in Taiwan. Setoxylobates taigangensis Ermilov sp. nov. differs from Setoxylobates foveolatus Balogh & Mahunka, 1967 in having smaller body size and setiform bothridial setae, and the absence of foveolae on the body. Revised generic diagnosis and an identification key to known species of Setoxylobates are provided. The taxonomic status and systematic placement of some related poronotic taxa are discussed, resulting in the following new taxonomic proposals: Protoribates Berlese, 1908 (=Lignobates Mahunka, 2006 syn. nov.); Setoxylobates Balogh & Mahunka, 1967 (=Plenoxylobates Hammer, 1979 syn. nov.). A new species name is proposed: Protoribates mahunkasandori Ermilov nom. nov. (=Lignobates berndhauseri Mahunka, 2006, preoccupied by Mahunka 1993). The initial generic status of Polyxylobates Hammer, 1973 and the position of Perxylobates mayuloeus Corpuz-Raros, 1979 in Perxylobates are supported.

AbstractA new species, Belondira bagongshanensis n. sp., extracted from soil under grass in Bagongshan Forest Park, Anhui Province, China, is described and illustrated. The new species is mainly characterized by a body length 1.6–2.1 mm; cephalic framework moderately sclerotized; odontostyle robust with a distinct lumen; anterior part of pharynx with a distinct fusiform swelling, bearing distinct sclerotized valve plates and basal expansion occupying about three-fifths of the total neck length; female genital system mono-opisthodelphic and anterior branch 0.8–1.6 times the corresponding body diameter; tail short and hemispheroid; male spicules 36–49 μm long and two widely spaced ventromedian supplements. The new species is close to B. wajahati, B. golden and B. eugeniae in possessing a short tail, a robust odontostyle with a distinct aperture and a moderately sclerotized cephalic framework. New sequences of 18S rDNA and the D2–D3 region of 28S rDNA of the new species were also identified.

A new species of Lamellarea (Oribatida, Lamellareidae) is described from hick twigs of southern live oak in Florida, U.S.A. (part of the Neotropical region). Lamellarea americana sp. nov. differs from most similar species, Lamellarea digitata and L. forceps by the ventrally inserted lamellar setae, the number of genital setae, the length of interlamellar setae, and the body size. Remarks on generic diagnosis and distribution of Lamellarea are presented.

A new species of Eremella Berlese, 1913 (Oribatida, Eremellidae) is described from a termite nest of Cornitermes silvestrii Emerson in Snyder, 1949 (Isoptera, Termitidae) in Brazil. Eremella vazdemelloi sp. nov. differs from Eremella ensifera Balogh and Mahunka, 1968 by the presence of short notogastral setae, the bothridial setae specifically directed posterolaterally, and the absence of tutorial ridges. Revised generic diagnosis and an identification key to known species of Eremella are presented. The taxonomic status of the eremellid genera Licnocepheus Woolley, 1969, Triteremella Kunst, 1971 and Afreremella Mahunka, 1973 are discussed, resulting in the following new taxonomic proposals: Eremella (=Licnocepheus syn. nov.), Eremella (=Triteremella syn. nov.), Eremella reticulatus (Woolley, 1969) comb. nov. (from Licnocepheus), Eremella simpliseta (Mahunka, 2011) comb. nov. (from Triteremella). Also, the generic status of Afreremella and Archeremella Balogh and Mahunka, 1974, and initial systematic placement of Afreremella luisiae Mahunka, 1973, Eremella kaszabi Csiszár, 1962 and Eremella matildebellae Mahunka and Palacios-Vargas, 1995 are supported.

A new species of Protaphorura Absolon, 1901 (Collembola, Onychiuridae), P. cykini sp.nov., is described from a cold karst cave in the Irkutsk region, Siberia, Russia. It is an obligate cave species with the largest body size (4.3–5.6 mm) of all congeners. The species is further characteristic by the pseudocellar formula as 3(2)2/022/33343, high number of vesicles in postantennal organ (65–71) and subapical organite protected with two papillae. A partial sequence of cytochrome oxidase I (COI DNA barcoding marker) gene is used to verify the taxonomic status of the new species and the barcode sequence is compared with other congeners available in GenBank database. Distribution and diversity of cave Collembola of Siberia is discussed.

A new species of free-living marine nematode is described from Itapuã beach, northeast of Brazil. Pomponema veronicae sp. n. differs from other species of Pomponema by having buccal cavity with large pointed dorsal tooth, two subventral teeth and pairs of denticles, gubernaculum with two L-shaped lateral plates and having a membrane at its distal end that connects to L-shaped plate, and presence of a ventral orifice at distal end of L-shaped plates. It also differs from other species in the size of spicules and gubernaculum. The new species is considered most closely related to Parapomponema species because of the L-shaped lateral plates of gubernaculum, but the taxonomic status of Parapomponema was reviewed and Parapomponema and Propomponema are now synonymized with Pomponema. Pomponema cyatholaimoides is considered as a species inquirendum and Pomponema carinatum is accepted as Pomponema loticum. An updated identification key to species of Pomponema is included.

Cataglyphis ficisp. nov., a member of the Cataglyphis livida complex, is described from the Estahban county of south-western Iran. The species is characterized by small body size and yellow to yellowish red body coloration with distinctly infuscated legs. Additionally, the taxonomic status of all known members of the Cataglyphis livida complex is updated. Cataglyphis lutea Pisarski, 1967, stat. rev. is raised to the species level and Cataglyphis viaticoides (André, 1881) is proposed as a senior synonym of Cataglyphis livida bulgarica Atanassov, 1982, syn. nov. and Cataglyphis albicans mixtus (Forel, 1895), syn. nov. Finally, a provisional key to members of the livida complex is provided.
