De Man

Two new species of sesarmid crabs of the genus Parasesarma De Man, 1895, are described from mangrove forests in Southeast Asia. Parasesarma paucitorum n. sp. is described from northern Sulawesi and is allied to P. leptosoma (Hilgendorf, 1869) but differs from the latter in the form of its carapace, leg proportions, the structure of the tubercles on the cheliped dactylus, and the male first pleopods. Parasesarma raouli n. sp. is described from southern Peninsular Malaysia and is differentiated from the allied P. charis Rahayu & Ng, 2005, and P. anambas Yeo, Rahayu & Ng, 2004, by the number and form of the tubercles on the cheliped dacylus, the shape of the male abdomen and structure of the male first pleopods.

The identity of the poorly known bagrid catfish Pseudomystus moeschii (Boulenger, 1890) is clarified and the species redescribed. Two new species of closely related bagrid catfishes are also described: Pseudomystus carnosus from the Way Seputih River drainage in the province of Lampung in the southern tip of Sumatra, and P. fumosus from the Pahang River drainage in eastern Peninsular Malaysia. Pseudomystus carnosus, P. fumosus and P. moeschii can be distinguished from congeners in having an enlarged posterior process of the post-temporal, presence of long hair-like epithelial projections on the skin and long tubular extensions of the sensory pores. Pseudomystus carnosus differs from the other two species in having a pointed (vs. rounded) tip of the nuchal shield, while P. fumosus differs from the other two species in having very well developed procurrent caudal rays which are sinuously curved along the anterior edges (vs. less developed procurrent caudal rays that slope evenly along the edges). A lectotype is designated for P. moeschii.

The phyline plant bug genus Randallopsallus Yasunaga, 2013 (Hemiptera: Heteroptera: Miridae: Phylinae) is rediagnosed, with discussion on its tribal placement in the subfamily Phylinae. Current evidence suggests that this unique genus is best placed in Pilophorini and may be closely related to Parastenaridea Miller, 1937. Two new species, Randallopsallus berastagi sp. nov. (from North Sumatra, Indonesia) and R. malayanus sp. nov. (Peninsular Malaysia), are described. A key is provided to facilitate the identification of the three known Randallopsallus species.

Two new species of the free-living marine nematode genus Deontolaimus (Leptolaimidae) are described from mangrove forests of the Can Gio Biosphere Reserve and Tien Yen, Quang Ninh, Vietnam. D. mangrovi sp. nov. is distinguished from D. papillatus de Man, 1880 and D. cangioensis sp. nov. by tail shape: conical and then elongated, without pointed tip. Deontolaimus cangioensis sp. nov. resembles D. papillatus in body shape, especially in the pointed tail terminus. D. cangioensis differs from D. papillatus in having a complicated gubernaculum with dorsally curved apophyses.

Two new species of Leptarma, L. dispersum n. sp. and L. reunionense n. sp. are described from Europa Island and Réunion Island, respectively. Genetically, based on the mitochondrial COX1 gene, both species are markedly divergent from other congeneric species. Phylogenetically, L. dispersum n. sp. shows close relationship with L. lenzii (De Man, 1895) while L. reunionense n. sp. clusters with L. aurifrons (Li, Ng & Shih, 2019) and the species pair L. moluccense (De Man, 1892) and L. paucitorum (Rahayu & Ng, 2009). Morphologically, the new species differ most significantly from congeners by the relative length of the ambulatory legs and the shapes of the first gonopods and carapace. After the description of these two new species, the number of species comprised in the genus Leptarma is raised to 20, four of them being distributed in and off East Africa.

AbstractTwo new species of freshwater crabs of the family Parathelphusidae are described from southern Thailand. Sayamia melanodactylus sp. nov. is one of the smallest members of the genus known, and seems to be most closely related to S. sexpunctata, but differing in carapace and male gonopod characters as well as in the colour of the fingers of its minor chelae (black against brown). Heterothelphusa fatum sp. nov. is related to H. insolita from nearby northeastern Peninsular Malaysia, but has a distinctly more swollen carapace, proportionately more slender ambulatory legs and a very differently structured major male chela.

Two new free-living marine nematodes of the family Oxystominidae are described from San Antonio Bay (Río Negro) and San José Gulf (Chubut). Litinium australis sp. n., is characterized by having a rounded tail, by the first and second crown of cephalic setae with different lengths, gubernaculum with apophysis and by the presence of at least four precloacal papillae; Thalassoalaimus nestori sp. n., is characterized by having a conical tail, cephalic setae equal in length, gubernaculum with rounded and dorso-caudally directed apophysis and two precloacal papillae. An emended diagnosis of the genus Thalassoalaimus and a key to species are given.

Two new species of Cardiodactylus crickets are described from unsuspected places in Southeast Asia: C. singapura n. sp., from within the island-city of Singapore, and C. thailandia n. sp. from Thailand. Descriptions focus on male and female genitalia, forewing venation and coloration. Data are provided for C. singapura n. sp. fine-scaled habitat and calling song. Consequences in terms of distribution of the genus and conservation are discussed.

Two New Species

We describe two new species of green pitviper from Southeast Asia that are morphologically similar to Cryptelytrops macrops, but can be distinguished from that species by genetic means, multivariate analysis of morphology and some aspects of coloration. Cryptelytrops cardamomensis sp. nov., is described from southeastern Thailand and the Cardamom Mountains of southwestern Cambodia. Cryptelytrops rubeus sp. nov. has been recorded from southern Vietnam and eastern Cambodia. These species have previously been confused with C. macrops, hence we also present here a redescription of this species, whose range is now restricted to Thailand, southern and central Laos, and northeastern Cambodia. All three species are present in Cambodia, but have disjunct ranges corresponding to three separate highland regions in southwestern (Cardamom Mountains), northeastern (western edge of the Kontum Plateau) and eastern (low elevation hills on the western edge of the Langbian Plateau) Cambodia for C. cardamomensis, C. macrops and C. rubeus respectively. However, there is still considerable morphological variation between geographically separated populations of C. macrops s.s., and greater sampling in southern and northern Thailand in particular may be required before the species diversity of this group is fully clarified.
