Wang, Yongjie & Liu, Zhiqi, 2009, Two new species of Parosmylus Needham (Neuroptera, Osmylidae) from China, with a key to Chinese species, Zootaxa 1985, pp. 57-62 : 58-59

Parosmylus liupanshanensis sp. nov.

( Figs. 1 , 3–12 )

Description Body length 15.9 mm. Forewing length 30.4 mm, width 10.2 mm; hindwing length 27.2 mm, width 8.9 mm.

Head. Vertex black, ocelli yellow, eyes grey. Antennae black, 71 segments; first segment of flagellum long, membrane of antennal socket yellow. Frons dark brown; labrum brown, maxillary palpi and labial palpi brown.

Thorax. Pronotum black, slightly longer than wide, and the posterior portion appreciably dilated. Mesonotum with yellow setae, scutellum yellow; metanotum dark brown, and black on both sides. Legs yellow; tibia with two distal brown spines; claws fuscous, with some small teeth.

Wings ( Fig. 1 ). Membrane hyaline, with numerous fragmentary brown spots. Pterostigma yellow centrally, and dark brown at both ends; nygmata distinct brown. Veins tan, cross-veins numerous. Costal crossveins with distal forks partially interlinked by occasional veinlets. One sc-r cross-vein close to the wing base; r-rs cross-veins numerous, edged by fuscous marks. Rs with 12–14 branches, and many irregular cross-veins, which do not form a gradate series; 3–4 presectoral cross-veins. MP fork close to the separation of MA from Rs; Cu forked at the base of wing, Cu2 with many pectinate branches interlinked by small veinlets. A1 and A2 also with distal pectinate branches. Hindwing with hyaline membrane, with few marks besides the brown pterostigma and nygmata. Costal cross-veins with few distal forks; MP forked at base, the distance between branches slightly wider at middle. Cu2 with many pectinate branches from middle to wing margin. A1 with oblique pectinate branches.

Abdomen black, with yellow setae.

Male ( Figs. 3–9 ). Tergite VIII quadrate; scent glands slender, generally below surface of integument, or occasionally extended from integument with a membranous fingerlike sac. Tergite IX narrow, and expanded ventrally; sternite IX approximately quadrate with a distal lateral process. Anal plate small, callus cerci round. Genitalia comprised of gonarcus and parameres. Gonarcus projects posteriodorsally, with an upturned ventral process, and a digitiform process at mid length in lateral view; baculum narrow. Parameres united in broad base, extended as a thin end which surrounded apically by membrane; one narrow haulm-like arm conjoint in the middle of paramere laterally.

Female ( Figs. 10–12 ). Tergite VIII broad, and sternite VIII small. Tergite XI narrow and ventrally tapered. Anal plate approximately cone-shaped, callus cerci round. Gonapophysis lateralis boat-shaped, and slightly curved in middle; stylus nearly fingerlike, and expanded in middle. Spermathecae oblong.

Type material. Holotype male. Ningxia: Liupanshan, 35º23’N, 106º20’E, VI.28.2007, leg. Gang Yao (CAU). Paratype. 14 males, 11 females. VI.26 –30.2007. same data as holotype.

Distribution. China (Ningxia)

Etymology. The name of new species refers to the locality Liupanshan. Remarks. This new species is easily distinguished from all others by the absence of gradate cross-veins, which generally form an integrated outer gradate cross-veins in other species.
