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

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 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.

Intertidal Fish

Microcotyle is one of the most diverse and controversial genera within the family Microcotylidae. To date, 131 species have been described in Microcotyle; however, more than half have been transferred to other genera, and several others have poor descriptions. Therefore, less than half of all Microcotyle species may be considered valid. In Chile, two species have been recognized, and unidentified Microcotyle have been found on several littoral fish, but there has been no effort to properly identify them. In this study, two new species of Microcotyle are taxonomically described from intertidal fish of the central (33°S) and south-central (36°S) regions of Chile. In this study, Microcotyle sprostonae n. sp. (collected mainly from Scartichthys viridis in central Chile) and M. chilensis n. sp. (collected mainly from Calliclinus geniguttatus in south-central Chile) were identified based on morphological and molecular analyses (ITS2 and 18S genes). Both species of Microcotyle principally differed from one another and from other valid species in the number of testes and clamps. The two new species also differed from one another by one base pair in the ITS2 and 18S genes and differed from other species of Microcotyle by several base pairs of both genes. Intertidal fish are mostly endemic to the Pacific coast of South America, and they have a limited geographical distribution that does not overlap with the type hosts of other Microcotyle species. Therefore, the two new species described here are distinguished from other congeneric species by morphological, genetic, and biological characteristics.

The genus Platyrhina from the northwestern Pacific was reviewed, including a redescription and neotype proposal for Platyrhina sinensis (Bloch and Schneider 1801), and the description of two new species. Platyrhina limboonkengi Tang 1933 is relegated to the synonymy of P. sinensis, both species having two rows of hooked thorns on the mid-dorsum of the tail. Specimens previously widely identified as P. sinensis, but characterized by one row of such hooked thorns, represented an undescribed species, herein named Platyrhina tangi Iwatsuki, Zhang and Nakaya sp. nov. Platyrhina hyugaensis Iwatsuki, Miyamoto and Nakaya sp. nov., known from specimens limited primarily to the Hyuga Nada Sea, off Miyazaki, the Pacific coast of southern Japan, is similar to P. tangi in having one row of hooked thorns on the mid-dorsum of the trunk and tail, but differs in having larger hooked thorns, not encircled by light yellow or white pigment on the orbital, nape and scapular regions, and a pair of hooked thorns (absent in P. tangi) anteriorly on the scapular region. Nominal species are discussed and key to northwestern Pacific species of Platyrhina is provided.

Two new species of Metacirolana from coral reefs in Indonesia are described and Metacirolana spinosa (Bruce, 1980) is recorded for the first time in Indonesia. Metacirolana lombok sp. nov. and Metacirolana mioskon sp. nov. show similarities with several other species of Metacirolana forming a species group within the genus, characterized by small body size (2.0–3.5 mm), smooth body surfaces, weakly produced rostrum, lack of dorsal carinae and abundant chromatophores.

Two New Species

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.
