Nyctiophylax (Paranyctiophylax) auriculatus Li 1998: 94-96, figs 4.22-4.24, nomen nudum.
Holotype male, PRC, Jiang-xi Province, Wu-yuan County, Qin-hua River, 57 km N of Wu-yuan, 29.15°N, 117.53°E, 25-v-1990, 250 m elevation, collected by JC Morse, Yang Lian-fang, and Sun Chang-fai, deposited in NAU.
PRC, Guang-dong Province: Bo-luo County, Mt. Luo-fu, unnamed stream, 400 m on trail to Shan-bei-shui, trailhead 3.2 km W of ridge of Mt. Cha, 23.3190°N, 114.0115°E, 290 m elevation, 01-vi-2004, Coll. JC Morse, Zhou Xin, CJ Geraci, 1 male (NAU).
The genitalia of the new species are similar to those of Nyctiophylax (Paranyctiophylax) hjangsanchonus (Botosaneanu, 1970) and Nyctiophylax (Paranyctiophylax) cascadensis (Malicky, 1995) in the short and broad preanal appendages and in the pair of long and slender phallic parameres. However, in lateral view, where the preanal appendages are semicircular in Nyctiophylax hiangsuchonus and triangular in Nyctiophylax cascadensis , they are somewhat quadrate in the new species. Also, the inferior appendages each have a mesal process in Nyctiophylax hiangsuchonus , a ventral process in Nyctiophylax cascadensis , and no conspicuous process in the new species.
Description of adult male.
Head and thorax light yellowish brown with yellowish antennae, pronotum light brown, meso- and metanota yellowsh-brown dorsally, pale yellowish lateroventrally with concolorous thoracic legs, forewings light brown. Length of body with folded forewings: 5.6-5.8 mm (n=2).
Male genitalia. Tergum IX membranous, short, trapezoid in dorsal view (Fig. 8C), with shallow incision on posterior margin. In lateral view (Fig. 8A), sternum IX tall, subquadrangular, with anterolateral margins convex, dorsal margins short and round, posterolateral margins almost straight and vertical, ventral surface about twice as long as dorsal margin; in ventral view (Fig. 8B), posterior margin nearly straight, anteromesal margin with broad and shallow excision. Tergum X lightly sclerotized, deeply divided apicomesally into 2 broad lobes in dorsal view (Fig. 8C). Without obvious intermediate appendages. Preanal appendages shorter than tergum X, almost square in lateral view (Fig. 8A), obliquely truncate; with long, stout mesoventral process (m.v.pro.pre.app.) tapering gradually to acute apex directed caudoventrad. Inferior appendages each with basal 2/3rds much broader than apical 1/3rd; basoventral process not visible in lateral view; distal 1/3rd narrower and curved mesad with obtuse apex in ventral and lateral views (Figs 8B, 8A). Phallus with sclerotized phallobase twice as long as phallicata, curved ventrad and tapering anteriorly and with pair of short blunt lobes posteroventrally; parameres (para.) longer than phallus, arising at ventral, anterior end of phallobase; phallicata membranous dorsally, without internal spines.
Female and immature stages.
Oriental Biogeographic Region, China (Jiang-xi, Guang-dong).
Auriculatus, Latin adjective, “ear-like,” referring to the shape of the preanal appendages in lateral view.
