Two new leech species (Hirudinida) representing the families Glossiphoniidae (Glossiphonia balcanica n. sp.) and Erpobdellidae (Dina prokletijaca n. sp.) are described. The populations from Montenegro assigned by Utevsky et al. (2013) and Grosser et al. (2015) to Glossiphonia nebulosa Kalbe, 1964 represent an new species, here described as G. balcanica n. sp. The new species can be easily be separated from Glossiphonia nebulosa by the reduction of the papillae. Dina prokletijaca n. sp. closely resembles D. dinarica Sket, 1968 and D. montana Sket, 1968 from which can be distinguished in the combination of the small and stocky body, dorsal surface with two wide and dark paramedian longitudinal stripes and ovisacs reaching the fourth somite after the female genital pore, and curled in their entire course. A key to the species of Glossiphonia Johnson, 1816 and Dina R. Blanchard, 1892 from the Western Balkans is presented.

A New Species

A new species of Gracixalus is described from northwestern Vietnam based on morphological differences and molecular divergence. Morphologically, the new species, Gracixalus ziegleri sp. nov., is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: (1) size small (SVL 28.1 – 30.5 mm); (2) head slightly wider than long; (3) vomerine teeth absent; (4) upper eyelid and dorsum without spine; (5) supratympanic fold distinct; (6) skin of dorsal and lateral surface of head, body and limbs rough, sparsely scattered with tubercles; (7) ventral skin granular; (8) tibiotarsal projection absent; (9) toes with moderately developed webbing, formula I1 – 11/2 II1 – 2III1 – 2IV2 – 1V; (10) dorsal surface of head and body brown to beige above, with an inverse Y-shaped dark brown marking, extending from interorbital region to central region of dorsum; (11) external vocal sac absent in males; (12) males with a nuptial pad on finger I. Phylogeneticially, the new species is a sister taxon of Gracixalus sapaensis and G. tianlinensis with well-supported values. Currently, the new species is known only from the evergreen montane tropical forest of Yen Bai Province at an elevation of ca. 2200 m a.s.l.

To reveal the diversity of Indonesian bent-toed geckos, we pay attention to Kalimantan (Borneo)—an island which has received less attention than other Indonesian islands such as Sumatra, Java, Sulawesi, the Moluccas, and the Lesser Sunda archipelagos. About 30 years after Hikida (1990) described three new Cyrtodactylus from Borneo, four more species were described, namely C. limajalur and C. muluensis in 2019, and C. hantu and C. miriensis in 2021, all by Davis et al. Through examination of the collection at MZB and three addition specimens collected from Tawau, we found several undescribed species, one of which we describe here. This new species is easily differentiated from all other congeners by the combination of the following characters: maximum SVL of at least 65.8 mm; no tubercles on dorsal surface of upper arm; tubercles present in the ventrolateral body folds; 28–30 paravertebral tubercles; 17–20 longitudinal dorsal tubercle rows; 39–46 ventral scale rows at midbody; 17–19 subdigital lamellae on fourth toe; precloacal pit with 5–7 pores in males arranged in a wide Λ-shape but absent in females; no enlarged transverse median subcaudals; paired dark brown semilunar-shaped markings on the upper nape. Further study is needed to reveal its molecular phylogenetic position and biogeographical history.

During general field surveys carried out recently to collect benthopelagic copepods from near the substrate of the shallow waters off Jeju Island, Korea, a few specimens of three new species of Stephos Scott, 1892, were collected. The new species are placed in the genus Stephos because of the following combination of features: absence of seta on the basal exite of maxillule, and male right leg 5 ending in an unarmed claw-like and/or mitten-like segment. Stephos jejuensissp. nov. can be distinguished from its congeners by body length 0.92 mm, left side of the female genital double-somite with protruding lobes, antennule that extends beyond the distal area of the genital double-somite, and the male leg 5 terminal complex. Stephos concavussp. nov. can be distinguished from its congeners by the genital double-somite with protruding lobes on both sides, and the presence of larger spinules on the distomedial margin of leg 5. Stephos fortipessp. nov. can be distinguished from its congeners by its longer body length, 1.12 mm long in the female, antennules that extend to the end of the genital double-somite, and the presence of a covered row of minute spinules on the ventral surface of the genital operculum in the female. Until now, 35 species of stephids were known worldwide.

AbstractFive new species of Rhigonema are described and illustrated from the gut of diplopods collected from the Philippines and Vietnam. R. flabellifer sp. n., R. golovatchi sp. n., R. rigonanae sp. n., R. spiridonovi sp. n. and R. voratum sp. n. are differentiated from one another and the remaining species in the genus by a combination of characters including form of the cephalic extremity, development and extent of the pilose region, female genital tract type, male and female tail shape, spicule form and number and disposition of the copulatory papillae. Two species, both from polydesmid diplopods, bear an unusual pedunculate, flap-like projection on each sector of the triangular oral aperture and have only thirteen copulatory papillae. Such projections have only previously been described from R. lanceacauda, a species from the West Indies that also shares a reduced and similarly arranged complement of thirteen male papillae. The morphology, bionomics and distribution of Rhigonema are discussed and evidence presented for the first time that nematophagy is practised by at least one species in the genus. Rhigonema leonilae (Sanchez-Velazquez, 1979) comb. n. is proposed for Ruizia leonilae Sanchez-Velazquez, 1979. Cinq nouvelles especes de Rhigonema Cobb, 1898 (Rhigonematida: Rhigonematidae) des Philippines et du Vietnam et observations sur la morphologie des formes indo-malaises et la nematophagie chez R. voratum sp. n. - Cinq nouvelles especes de Rhigonema provenant des intestins de diplopodes collectes aux Philippines et au Vietnam sont decrites et illustrees. R. flabellifer sp. n., R. golovatchi sp. n., R. rigonanae sp. n., R. spiridonovi sp. n. et R. voratum sp. n. sont differencies les uns des autres et des autres especes du genre par une combinaison de caracteres incluant la forme de l'extremite cephalique, le developpement et l'etendue de la pilosite, le type de tractus genital femelle, la forme de la queue du male et de la femelle, la forme des spicules et le nombre et la repartition des papilles copulatrices. Deux especes, provenant toutes deux de Diplopodes Polydesmides, portent une projection inhabituelle, pedonculee, en forme de languette, sur chacun des secteurs de l'ouverture buccale triangulaire et comptent seulement treize papilles copulatrices. De telles projections n'ont ete precedemment decrites que chez R.lanceacauda, une espece originaire des Antilles, qui exhibe egalement un cortege reduit de treize papilles chez le male avec la meme repartition. La morphologie, le comportement et la repartition des Rhigonema sont discutes et la preuve est apportee pour la premiere fois que la nematophagie est pratiquee par au moins une espece de ce genre. Rhigonema leonilae (Sanchez-Velazquez, 1979) comb. n. est propose pour Ruizia leonilae Sanchez-Velazquez, 1979.

Xiphinema mazandaranense n. sp. is described and illustrated. The new species belongs to morphospecies group 6, which is characterised by having two equally developed female genital branches that have spines in the uteri and a short, rounded tail. The new species is characterised by having spines in the tubular portion of the uterus, body 3.7-5.2 mm long, odontostyle 163-173 μm long, odontophore 96-100 μm long, body 62-80 μm diam., rounded tail, four juvenile stages, males rare with three ventromedian supplements next to the adcloacal pair and spicules 85 μm long. The polytomous identification codes of the new species are: A4-B3-C7b-D6-E456-F45-G4-H2-I23-J7b-K2-L1. The new species appears closely related to the members of X. pyrenaicum group which are characterised by a rounded tail with or without an inconspicuous projecting bulge and a uterus devoid of Z-differentiation but showing spiniform structures. The new species differs from members of the X. pyrenaicum group, which includes the recently described X. iranicum, by a more rounded tail without any projection. Beside morphological and morphometric data, molecular analyses of the near-full-length small subunit rDNA gene (SSU) placed the new species in close relationship with some species belonging to Xiphinema morphospecies group 6 and further separated this species from the X. pyrenaicum complex.
