Two New Species

Stenosternum cordata sp. nov. and Stenosternum bifurcata sp. nov., new to science, are described, which is the first record of Hoplomegistidae from Asia. Stenosternum cordata sp. nov. is distinguished by its heart-shaped latigynal shield with two pairs of setae along the lateral margin, and two pairs of setae along the posterior margin of the sternal shield. Stenosternum bifurcata sp. nov. is distinguished by having remarkable bifurcate corniculus, six pairs of setae on the sternal shield and three pairs setae on the latigynal shield. The family Hoplomegistidae Camin & Gorirossi, 1955 is redefined and a key to adult females of species is provided.

Electronmicroscope Study

Two new species of Sphaeromopsis (Sphaeromatidae: Isopoda) from Iran are described based on light and electronmicroscope study: Sphaeromopsis sarii sp. nov. from the coasts of Kish and Qeshm Islands, and S. persikolpos sp. nov. from Kish Island, Qeshm Islands and the southern coasts of Iran. The two species are sympatric in most areas. Sphaeromopsis sarii is distinct among other species in the genus for having a pleotelson with a faint dorsomedial furrow and a broadly rounded apex. Sphaeromopsis persikolpos sp. nov. is unique for the single suture at either side of the posterior margin of the pleon, a narrow pleotelsonic apex, and the uropodal exopod extensions that reach well beyond the pleotelsonic apex.

Orthezia cheilanthi, n. sp.—Adult ♀ Length, 3.5 mm. Width, 3-3.5 mm. Length + ovisac, 6-8 mm. Width of Ovisac 3-4 mm. Body above covered with whtie secretion, which forms lateral and sub. dorsal longitudinal keels. A well-defined subdorsal furrow between the keels and the lateral margin formed by 3 or more rows of paltes; these are smaller than the projecting marginal plates, which are flattened; caudal plate and the 3 or 4 plates on each side of it very little longer than the lateral plates. The structure of the secretion is compact; in most of the other species of Orthezia it is fluffy.

Two new species of Hyphessobrycon are described from the upper rio Tapajós basin, Mato Grosso, Brazil. Hyphessobrycon melanostichos is distinguished from its congeners by the combination of a conspicuous longitudinal broad black band beginning on the posterior margin of orbit and reaching the tip of middle caudal fin rays, a distinct vertically elongate humeral spot, and 16 to 18 branched anal-fin rays. Hyphessobrycon notidanos is distinguished from its congeners by the combination of an elongate dorsal fin in mature males, a vertically elongate humeral spot, 2-4 maxillary teeth, iii,8 dorsal-fin rays, and 16 to 21 branched anal-fin rays.

The sharpshooter genus Lebaziella is described and placed in the tribe Cicadellini. Two new species of Lebaziella gen.nov. are described and illustrated: the type-species L. renatae sp. nov. (Bahia State, Brazil) and L. viridis sp. nov. (Rio de Janeiro, São Paulo, and Paraná States, Brazil). Species belonging to the new genus can be distinguished from other genera of Cicadellini based on the following characters: (1) pronotum narrower than head with lateral margin parallel; (2) male pygofer without processes; (3) subgenital plate longer than pygofer with many microsetae distributed across its surface; (4) aedeagus with an unpaired apical process, and (5) paraphyses absent.

A new genus of family Perlodidae, Parisoperla Huo & Du, gen. nov. is described including two new species from Guizhou Province in southwestern China. Both sexes of the new genus are characterized by the posterior margin of tergum 10 with a sclerotized process. The male membranous aedeagus is covered ventrally by patches of fine spines.

Two New Species

Previously, only three of seven species in the Asian genus Notacanthurus were reported both nymphs and imagoes, and no Chinese species was found. Here two new species collected from China, which are named as Notacanthurus maculatus sp. n. and N. lamellosus sp. n. respectively, are described and pictured in detail. The nymph of N. maculatus sp. n. has following combined characters: posterior margin of sternum IX straight, claws with two subapical denticles, and gills V–VI with arrow-like accessory lobes. The male imago has unspecialized anterior margin of head and Electrogena-like penis lobes. The second species N. lamellosus sp. n. is more distinguishable. Its nymph has pale dots on head, median dorsal ridges on abdominal terga I–IX, claws with five subapical denticles, and dorsal lamellae of gills II–IV divided into two portions. Anterior margin of male imago is not protruding either, forewings have less pigmented crossveins between Sc and R1, and penis lobes have apical and ventral sclerites. A key to all known nymphs of the genus is provided.

Two new species, Cleantiella ampliscutula sp. nov. and Pentias pluriarticulatus sp. nov., are reported from Korean waters with keys to all known species of the genera Cleantiella and Pentias. Cleantiella ampliscutula sp. nov. can be distinguished from its congeners by the following characteristics: the body is relatively small; pereonite 1 is expanded anterolaterally; coxal plates 2–7 are triangular; the pleon has three partial sutures; the pleotelson is widening posteriorly on the lateral margin; the flagellum of the antenna is single-articled; and the maxillipedal palps are four-articled. Pentias pluriarticulatus sp. nov. can be distinguishable from its congeners by the following characteristics: the lateral margins of the body are parallel; the anterior margin of the cephalon is slightly concave and has a small median notch; the coxal plates are invisible dorsally on pereonites 2–4, but visible on pereonites 5–7; the pleon has three partial sutures; the flagellum of the antenna is composed of nine articles; and the distal ends of the uropodal endopods are sinuous.

First Time

Three amphipods of the family Photidae collected from Korean waters are reported here with detailed descriptions and illustrations. The Korean materials of Gammaropsis examined in this study are readily assigned to G. longipropodi by the characteristic shape of gnathopod 2 in males: not slenderly produced posterior margin of the carpus, uniform width of very elongate propodus, and the transverse palm. Among the species of genus Photis, P. fischmanni is only one species bearing stridulation ridges of the basis on gnathopod 2 and coxa 3 simultaneously in females, until now. However, Photis stridulus sp. nov. also show this characteristic but is clearly distinguishable from P. fischmanni by the weak setation of the appendages, smaller eye on the anterior cephalic lobe, and the slender carpus and propodus on gnathopod 1. The genus Podoceropsis is recorded from Korean waters for the first time with the discovery of P. clavapes sp. nov. This new species is characterized by its elongate propodus and dactylus on gnathopod 2 and the shape of the posterior lobe of the basis on pereopod 5 in mature males.

Length, apex of head to tips of wings 5.75 mm.; width of wing at apex of clavus 1.75 mm.Vertex broad, transverse, resembling pini, median length distinctly less than half as great as width at middle of posterior margin; anterior margin very broadly arcuate, posterior margin scarcely less so.
