Liu, Xingyue, Aspöck, Horst & Aspöck, Ulrike, 2014, New species of the genus Nipponeurorthus Nakahara, 1958 (Neuroptera: Nevrorthidae) from China, Zootaxa 3838 (2), pp. 224-232 : 229-230

Nipponeurorthus furcatus sp. nov.

( Figs. 2 , 9–11 )

Description. Male. Body length 4.0 mm; forewing length 7.1–7.4 mm, hindwing length 6.5–6.9 mm.

Head yellow. Compound eyes blackish brown. Antennae yellow. Mouthparts yellow; mandibles with brownish tips.

Thorax yellow, with yellowish setae. Legs yellow throughout, with yellowish setae. Wings ( Fig. 2 ) elliptical, slightly yellowish brown, with pterostigmatic areas yellowish brown. Forewing with distal margin brown, and with distinct brown markings on gradate crossveins as well as on 1r-rs; other less distinct brown markings present on distal branching points of most longitudinal veins. Veins yellowish brown except for those in dark markings brown. Hindwing much paler than forewing, with distal dark edging much shorter and paler than that on forewing. Veins pale yellow, with 1r-rs and 2r-rs brown.

Abdomen yellow. Tergite 9 and sternite 9 fused into a ring-like structure; tergite 9 ( Fig. 10 ) anteriorly truncate and posteriorly broadly concaved in dorsal view; sternite 9 ( Fig. 11 ) posteriorly feebly protruding at middle. Gonocoxite 9 ( Figs. 9–11 ) robust on proximal half and strongly incurved on distal half, ventrally with an up curved short lobe separated from the main body of gonocoxite 9; inner surface with a small hairy tubercle; gonostylus 9 terminally rounded and bearing a spinous lobe. Ectoproct ( Figs. 9–10 ) broad, directed posteriad, and subtrapezoidal and slightly concaved on posterior margin in dorsal view. Complex of gonocoxite+gonostylus+gonapophysis 10 ( Fig. 11 ) proximally robust, distally with a slenderly spinous projection, which laterally bears a feebly sclerotized flat lobe. Gonocoxite 11 ( Fig. 10 ) present as a simple, transverse, sclerotized band; gonostyli 11 ( Fig. 10 ) present as a posteriorly bifurcated sclerite. Hypandrium internum invisible.

Female. Unknown.

Type materials. Holotype ♂, CHINA, Yunnan, Lvchun, Qimaba, Dapingzhang [22°50′N, 102°13′E], 1600 m, 21.VII.2013, Yang Zhao ( CAU). Paratype 1♂, same as holotype ( CAU).

Etymology. The specific epithet “ furcatus ” refers to distally bifurcated male gonocoxite 9.

Distribution. China (Yunnan: Lvchun).

Remarks. This new species appears to be somewhat related to N. flinti , N. multilineatus , and N. punctatus by having a similarly bifurcated male gonocoxite 9, but it can be distinguished from its related species by the forewings with distal margins broadly tinged brown. In N. flinti , N. multilineatus , and N. punctatus , the forewings lack brown edgings. Moreover, the complex of male gonocoxite+gonostylus+gonapophysis 10 is obviously different from that in the other three species.
