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.

De Man

Three species of the genus Automate De Man, 1888 are described herein, including two new species: A. anacanthopusoides sp. nov. and A. spinosa sp. nov.. Automate anacanthopusoides sp. nov. can be easily identified by the presence of a rostrum, the notch on the lower margin of the major chela, the stout minor cheliped and the cutting edge of the pollex not dentate, and by the absence of spines on the ventral margin of the propodus of the third and fourth pereiopod. Automate spinosa sp. nov. can be easily identified by the nearly straight anterior margin of the carapace, and the presence of spines on the ventral margin of the propodus of third and fourth pereiopod. A key of all species of the Automate is provided.

Deep Impression

A small robust species, length 1.5-2.5 mm.Front of the male deeply concave, clothed with short bristle-like hairs, sparsely granulate-punctate, surface opaque, with a long, shining, median carina; second suture of the antennal club subtransverse. Pronotum wider than long, 5.5:3.5; sides slightly rounded, narrowing on the anterior half, constricted behind the anterior margin; the constriction extends across the dorsum, widening on the disk thereby simulating a wide, deep impression on the anterior third; anterior margin is broadly rounded; the surface is moderately clothed with short setae and the punctures are large, dense, and deep.

The Family

A new genus, Dozierana gen. nov., is erected for Thionia gibbicollis Dozier, 1931 which is transferred from the family Issidae Spinola, 1839 to the family Nogodinidae Melichar 1898, subfamily Colpopterinae Gnezdilov, 2003. This new combination increases the fauna of Colpopterinae of Haiti Island up to 3 genera with 5 species. Accordingly, the family Issidae is no longer formally known from the island. Dozierana gen. nov. is characterized by wide metope, with distinct median carina and very weak sublateral carinae, upper margin of metope concave; coryphe 3 times as wide as long medially; large ocelli present; pronotum short, with 4 lateral carinae, its anterior margin strongly convex and posterior margin strongly concave; mesonotum 7 times as long as pronotum along midline, greatly elevated along median carina, with two lateral carinae joined with median one in shape of inverted “V”; fore wings wide, with wide hypocostal plate and rich cross-venation through whole wing, except subcostal area; basal cell large oblong-oval; costal vein with distinct upper keel appearing as a separate vein; clavus as long as whole wing, open; hind tibiae with single lateral spine subapically.

Two new species of Cossura Webster & Benedict, 1887 were found in material collected during sampling from the terminal lobes of the Congo deep-sea fan. They were described using light and scanning electron microscopy. Cossura platypus sp. nov. has 15–17 thoracic chaetigers, a prostomium longer than it is wide, with a widely rounded anterior margin, an abruptly expanded posterior prostomial ring the same length as the peristomium, without a mid-ventral notch, a branchial filament attached to the midlength of chaetiger 3, and a pygidium with three anal cirri. Cossura platypus sp. nov. is similar to C. brunnea Fauchald, 1972 but differs in the shape of the prostomium, which is widely rounded anteriorly in C. platypus sp. nov. and is broadly triangular in C. brunnea; furthermore, C. platypus sp. nov.is uniformly pale, whereas C. brunnea has dark pigmentation. Cossura candida Hartman, 1955 differs from C. platypus sp. nov. in the conical shape of the prostomium and 24–35 thoracic chaetigers. Cossura flabelligera sp. nov. has 16–19 thoracic chaetigers, a conical prostomium, and a branchial filament arising from the posterior part of chaetiger 2; the entire body, including the chaetae, is covered by a thick mucous sheath similar to the tunic of flabelligerids. Cossura flabelligera sp. nov. resembles C. longocirrata Webster & Benedict, 1887 in the position of the branchial filament, the shape of the prostomium, and the number of thoracic chaetigers; it differs in having a thick mucous sheath. This character seems to be unique for the Cossuridae.

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.

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.

Okubasca Dworakowska, 1982, formerly treated as a subgenus of Empoasca Walsh, 1862, is elevated to status as a separate genus. Two new species of Okubasca from China are described and illustrated: Okubasca convoluta Yu & Yang sp. nov.; Okubasca paracalvata Yu & Yang sp. nov. Okubasca convoluta is similar to O. okubella in having the aedeagal shaft about as long as the preatrium but differs in having the aedeagus of uniform thickness in lateral view, the anal tube process straight and the face mostly black. Okubasca paracalvata resembles Okubasca calvata in aedeagal shape, but differs in having a lamellar swelling and a small tooth on the dorsal side of the aedeagus, and the vertex anterior margin rounded.

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.

Morphological Differences

The present study tries to focus on describing two new species belonging to genus Gammarus from western Iran along the Zagros Mountains range. The most remarkable feature of Gammarus hegmatanensis sp. n. is the shape of epimeral plate 3, which is sharply pointed posteriorly with a distinct lobate anterior margin. This species has some similarities with and differences from some other species of Gammarus pulex–group such as G. parthicus and G. syriacus. The other species, G. sirvannus sp. n. with elongated eyes is similar to G. duebeni, G. lobifer, G. balutchi and G. loeffleri, but it shows prominent morphological differences and a distinct geographical distribution from these species. These new findings shed more light on the information available on amphipod fauna of Iran.
