Luo, Yang, Liu, Jing-Jie & Feng, Ji-Nian, 2019, Two new species in the genus Indolipa Emeljanov, 2001 (Hemiptera: Fulgoromorpha: Cixiidae: Pentastirini) from China, Zootaxa 4560 (1), pp. 184-194 : 185-186

Genus Indolipa Emeljanov, 2001

Indolipa Emeljanov 2001:72 .

Type species: Oliarus indiensis Van Stalle, 1991

Amended diagnosis. Total length varies from 5.4–8.9mm. Head including eyes narrower than pronotum. Face and vertex black with yellow carinae and borders. Vertex one to 1.6 times as long as broad. Posterior margins roundly and acute-angled, deeply U-shaped or arcuate; subapical transverse carina connected or not to the anterior margin by two small carinae ( Figs. 3, 8 ). Frons flat at base, median carina well-developed, incomplete or absent, lateral margins elevated. Frontoclypeal suture gently bent and widest at level of antennae. Median ocellus clearly visible at center of frontoclypeal suture ( Figs. 4, 9 ). Pronotum tapered with distinct carinae, strongly incised in middle. Mesonotum with five prominent concolorous carinae, protruding medially, descending laterally ( Figs. 3, 8 ). Forewing hyaline and longer than abdomen, tectiform, 2.7 to 3.4 times as long as broad; veins brown, with conspicuous tubercles; venation is similar to that of Oliarus Stål , with 9–12 apical cells ( Figs. 5, 10 ). Legs yellowish, generally with 3–6 tibial lateral spines. Metatibiotarsal formula 6/ (6–7)/ 5, metabasitarsus distally with 6–7, 2 nd metatarsal joint with 5 teeth without platellae.

Male terminalia. Anal segment and pygofer symmetrical; anal segment with various apical caudo-ventral processes ( Figs. 16 , 24 ). Pygofer usually without medioventral process ( Figs. 15 , 20 ). Gonostyli with dorsal finger- or spine-shaped process near midlength between the base and dilated apex ( Figs. 13, 14 , 21, 22 ); nearly symmetrical. Aedeagus structurally complex and variable among species.

Female genitalia. Structurally variable among species. Posterior margin of 7 th sternite (pregenital sternite) with caudal margin usually convex, medially rounded; sclerite usually triangular, sometimes more circular. In some species, the posterior margin of the 7 th sternite less curved. Ovipositor reduced, in ventral view gonocoxa VIII usually small, gonapophysis VIII (first valvula) and gonapophysis IX (second valvula) comparatively thin and elongate, reduced in various species. Abdominal 9 th tergite caudally with a distinct wax plate.

Remarks. The distinguishing characters of Oliarus indiensis Van Stalle, 1991 have been modified as follows: the genitalia of both males and females have been more precisely described. These changes are described in the diagnosis section.

Indolipa Emeljanov, 2001 is distinguished from all other Pentastirini by the unique characters of the male genitalia: Gonostyli with dorsal finger- or spine-shaped process near mid-length between base and dilated apex ( Figs. 13, 14 , 21, 22 ). Pygofer usually without medioventral process ( Figs. 15 , 20 ). Aedeagus screw-shaped in some species.

Distribution. China (Tibet, Shaanxi, Gansu, Hubei, Guangxi, Taiwan), India, Indonesia (Borneo), Malaysia, Myanmar, Singapore, Sri Lanka.
