Two new species of lotic-breeding salamanders, Hynobius sematonotos and H. oyamai, are described from Chugoku district and northeastern Kyushu district, respectively, western Japan. They are members of the so-called H. naevius group and are phylogenetically close to H. naevius, H. katoi, and H. hirosei but divergent from them with large genetic distances. These new species have been treated as Chugoku and northeastern Kyushu lineages, respectively, of H. naevius to which they are morphologically very similar. However, these new species can be differentiated from H. naevius by several morphological traits. Hynobius sematonotos is characterized and discriminated from other species by combination of small body size, a shallow vomerine teeth series with small number of vomerine teeth, small number of upper and lower jaw teeth, relatively long head and snout, and large upper eyelid, relatively short axilla-groin, reddish purple ground color with grayish brown marking on the dorsum, and reddish to bluish gray ventral ground color with relatively large markings varying from pale-white to white. Hynobius oyamai is characterized and discriminated from other species by large body size, moderately deep vomerine teeth series with a medium number of vomerine teeth, large number of upper and lower jaw teeth, relatively wide internarial and long fifth toe, bluish purple ground color sometimes with pale white marking on dorsum. Hynobius sematonotos occurs in Honshu, disjunct from H. naevius and H. oyamai that occur allopatrically in Kyushu.

AbstractTwo new species of Atractus are described from Venezuela uplands and highlands on two northern Andean cordilleras. Atractus acheronius, known only from Sierra de Perijá, can be distinguished from congeners by having 17 dorsal scale rows, presence of preocular scales, seven upper and lower labials, seven maxillary teeth, 166 ventrals in the single female, 23 subcaudals, dorsum brown with small dark brown dots, large body size, huge body diameter, and small tail size. Atractus multidentatus, known only from north versant of the Cordillera de Mérida, can be distinguished from congeners by having 17 dorsal scale rows, eight upper and lower labials, 18 maxillary teeth, 153 ventrals in the single female, nine subcaudals, dorsum reddish brown with five longitudinal dark brown stripes, small body size, small body diameter, and small tail size. Additionally, a discussion concerning the species description of Atractus based on unique specimens is provided.

Two new species of the genus Capillaria (Nematoda: Capillariidae) are described from the intestine of marine fishes from the Pacific coast of Canada. Capillaria freemani sp.nov. from the skates Raja rhina (type host), R. kincaidi, and R. stellulata (family Rajidae) is characterized by the presence of a pseudobursa provided with a tail projection and lateral rays in the male, spiny spicular sheath, long spicule (0.65–0.98 mm), and large body size (up to 25.76 mm long in the male and 38.13 mm in the female). Capillaria parophrysi sp.nov. from the flatfish Parophrys vetulus (family Pleuronectidae) is characterized mainly by the small body size (male up to 5.74 mm in length and female up to 10.42 mm), smooth spicular sheath without spines, the length of spicule (0.28–0.37 mm), and by the presence of two lateral rays and absence of a tail projection in the pseudobursa of the male.

Two new species of Serratella Edmunds (Ephemeroptera: Ephemerellidae: Ephemerellinae: Hyrtanellini) are described based on larvae from China and Iran. Serratella brevicauda, new species, is distinguishable from other Hyrtanellini based on its short caudal filaments and its relatively large body size. Serratella elissa, new species, is distinguishable from other Hyrtanellini based on a combination of its having paired tufts of spatulate setae and no paired spines on abdominal terga and having tarsal claws with denticles nearly subequal in size. The state of Asian Serratella systematics is reviewed, and some problems of Hyrtanellini systematics are discussed. Modifications to a recent identification key for ephemerellid larvae are suggested.

We describe a new species of fan-throated lizard of the genus Sitana from the Deccan peninsula of India. The new species is from the Sitana sivalensis clade and can be readily diagnosed morphologically from S. sivalensis, S. fusca and S. schleichi by having the dewlap extending beyond forearm insertion. The new species differs from all other congeners in the combination of morphological characters such as a feebly serrated dewlap with a dark blue line on the throat in adult males (versus  a well serrated dewlap with a bright blue patch and orange spots in S. ponticeriana complex), small body size (versus a large body size in S. gokakensis and S. thondalu) and a relatively smaller dewlap size (relatively larger in S. laticeps, S. spinaecephalus, S. dharwarensis, S. gokakensis, S. thondalu, S. marudhamneydhal, S. ponticeriana and S. visiri). The new species was found to be commonly distributed in arid and open habitats as well as in farmlands and plantations in northern Andhra Pradesh, eastern Madhya Pradesh and most parts of Chhattisgarh and Odisha states.

A large sample of Siphonophoridae from Brazil was studied; two morphological groups could be distinguished. Here species considered to be from the genus Columbianum Verhoeff, 1941 are examined in detail. The genus is known from Central and South America (Guatemala, Panama, Honduras, Guiana, Colombia, Peru and Brazil) and is characterised by a clear demarcation between head and rostrum in combination with long antennae, clearly surpassing the tip of the rostrum. A list of previously described species considered to belong to the genus is given; three new species are described: C. major sp. nov. has a large body size and a small head, C. nahvalr sp. nov. has a particularly pronounced domed head and a more castellated appearance to the body, C. adisi sp. nov. has a small body size and a very characteristic hind margin to the pleurites. Variation in the state of preservation of specimens hinders a diagnosis, but the examination of the accessory claw and details of the metazonital limbus and pleurite edges are helpful. Unusually for Diplopoda, the male gonopods are not very useful for identification. Ecological comments are given for each new species, one of which, C. adisi sp. nov., is from the seasonally flooded forest and appears to avoid inundation by climbing trees.

Three new species of the order Monhysterida are described based on specimens obtained at depths of 8081 and 9177 m in the Kermadec Trench. Thelonema clarki sp. nov. is characterised by a large body size (3230–4461 µm), short cylindrical buccal cavity, gubernaculum without apophyses, and long conico-cylindrical tail. This is the first record of the genus since its original description over two decades ago from the Peru Basin. Metasphaerolaimus constrictus sp. nov. is characterised by a relatively long body (1232–1623 µm), slightly arcuate spicules without gubernaculum, and conico-cylindrical tail with inner cuticle conspicuously thickened immediately anterior to cylindrical portion. Monhystrella kermadecensis sp. nov. is characterised by a circle of papillose outer labial sensillae slightly anterior to the four short cephalic setae, gubernaculum with caudal apophyses, the presence of distinct cuticularised piece along anterior vaginal wall, and a relatively short conical (males) or conico-cylindrical tail (females) with conical, ventrally-curved spinneret. M. kermadecensis sp. nov. can be differentiated from all other species of the genus, and, indeed, the entire family, based on the variable position of the anterior gonad relative to the intestine. The new species is classified within the Monhysteridae, and not the closely-related Xyalidae, based on the small body size, a smooth cuticle, and the presence of six outer labial papillae and only one testis. Further work is required to clarify the placement of M. kermadecensis sp. nov. relative to other monhysterid genera. A tabular key to all ten valid Metasphaerolaimus species is presented.

A new species of the Macrophthalmus telescopicus complex is described from Japan. The new species is closely allied to M. telescopicus (Owen, 1839), M. milloti Crosnier, 1965, and M. serenei Takeda & Komai, 1991. Macrophthalmus microfylacas sp. nov., however, is distinguished from these three species by the shape of the second and third anterolateral teeth, the shape of the gap between the first and second teeth, and a small body size. The new species can also be differentiated from M. milloti and M. serenei by the shape of the subproximal tooth of the male cheliped dactylus, while it differs from M. telescopicus by the shape of the G1.

Two new species of palpigrades are described: a soil-dwelling species of the genus Koeneniodes Silvestri, 1913 from a broadleaf forest in Tibet and an extraordinary cave-dwelling species from Jinhua cave in China belonging to Prokoenenia Börner, 1901. Koeneniodes tibetanus sp. n. is related to Koeneniodes spiniger from Thailand. The two species share the presence of four thick and spiniform setae on the second lobe of the female genitalia; they differ in the number of thick setae on opisthosomal sternite IV, the number of cheliceral teeth, the coxal setal formula, and the morphology of the spiniform setae. Prokoenenia sarcodactylica sp. n. is based on an immature female from Jinhua Cave, Beijing. The presence of 18 finger-shaped blades in the lateral organs—unique among palpigrades –, the large body size (2150 μm) and the extremely long basitarsus IV (205 μm) indicate that the new species is the first undoubtedly cave–adapted Prokoenenia. This is also the first record of the genus Prokoenenia from China.

Two new species of soldier beetles (Coleoptera, Cantharidae) from the Priabonian deposits in Yantarny, Russia (Baltic amber) are described. Cantharis crisantha sp. nov. is characterized by its relatively small body size, laterally rounded prothorax, and simple claws with a small basal tooth. Of particular interest, this specimen has its aedeagus extruded—a feature described for the first time in a representative of the genus Cantharis found in amber, and something rarely seen in all known fossil species of the Cantharidae family. The second described species, Cantharis raeorum sp. nov., is characterized by a pronotum with straight sides and a transverse and concave part near the posterior margin. The species are compared with earlier reported fossil Cantharis.
