Singapora Mahmood, 1967a: 20 ; Chiang & Knight, 1990a: 240 Erythroneuropsis Ramakrishnan & Menon, 1973a: 37

Description. Body robust. Ground color yellowish to green, sometimes dark, usually with central blackish spot at transition from crown to face. Head narrower or as wide as pronotum, crown fore margin paralleled to hind margin, coronal suture distinct, almost extending to anterior margin of vertex. Ocelli well developed. Face broad, slightly produced in profile, anteclypeus broad, lorum large. Fore wing with four apical cells parallel-sided, first apical cell longest and broadest, the other three equal in width, third apical cell shortest, fourth apical cell reached wing apex; AA vein distinct. Hind wing venation usual for Erythroneurini , without RA vein.

Male 2S abdominal apodemes usually broad, short to long. Anal tube appendage well developed. Male 9th sternite with two sclerites protruded cephalad.

Pygofer side broad, denticulate at dorso-caudal angle, with several long fine setae scattered near ventral margin and at lower basal angle; pygofer dorsal appendage and ventral appendage absent. Subgenital plate nearly triangular, broadened basally, outer margin straight, with group of macrosetae on basal outer margin and rows of marginal microsetae from near base to apex, with about 1–5 macrosetae in line in the center near outer margin. Style slim and long, apical part extremely elongated, curved laterad, basal part short, slightly produced on inner margin subapically, with some furrows apically; preapical lobe small, with a few microsetae on it. Connective triangular. Aedeagal shaft usually tubular, sometimes compressed, curved dorsad; preatrial process well developed, articulated with shaft, as long as or longer than shaft, dorsal apodeme moderately developed, forked in dorsal view; gonopore subapical on ventral surface.

Remarks. This genus is similar to Imbecilla Dworakowska, 1970 in having ocelli and the fourth apical cell of fore wing reaching wing apex, but the subgenital plate has a group of macrosetae basally along the outer margin, the style is long and without a second extension, and the aedeagus has a well developed preatrial process.

Distribution. China (Beijing, Fujian, Guangdong, Hainan, Hunan, Jiangsu, Jiangxi, Shaanxi, Shandong, Sichuan, Taiwan, Yunnan, Zhejiang); India; North Korea; Singapore; Thailand; Uzbekistan.
