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 : 186-187

Indolipa fopingensis sp. nov.

( Figs. 1–5 , 11–18 )

Diagnosis. Indolipa fopingensis is externally identical to I. gansuensis ; but these species are readily distinguished by: 1) the processes of left lateral sinuation of endosoma at basal portion ( I. fopingensis with a long and slender spine, directed left-cephalad, but I. gansuensis with a stout bifurcated process, the upper ramule acute and thin, directed left side, the lower one blunt and stout, directed cephalad); 2) the processes on left lateral sinuation of endosoma on right lower lateral of dorsal margin ( I. fopingensis with a stout and acute spine, with serrate apical margin, directed right-dorso-cephalad but I. gansuensis without process); 3) the processes on left lateral sinuation of endosoma in the middle area ( I. fopingensis without process, but I. gansuensis with an undulate and fingershaped spine, directed cephalad).

Description. Male. Body length (from apex of vertex to tip of forewings) 6.0–6.2 mm.

Head. Vertex ( Figs. 1, 3 ) black, about 1.4 times as long as broad, with a distinct subapical transverse U-shaped carina, connected with anterior border of vertex by two small longitudinal carinae, median carina absent. Posterior margin deeply excavated, lateral margins elevated. Face black with carinae and margins yellowish. Frons with median carina well-developed, fork of median carina near apex. Rostrum ( Fig 2 ) reaching hind coxae; apically black.

Thorax. Pronotum ( Figs. 1, 2, 3 ) black with yellowish carinae and borders, median carina indistinct. Mesonotum ( Figs. 1, 3 ) black with concolorous carinae. Tegmina ( Figs. 1, 2, 5 ) hyaline, 2.8 times as long as broad, veins yellowish with dark brown granules without setae; apical and stigma brown fumated costal margin brown with protruding granules. Venation pattern: RA unbranched, RP 3-branched, cell C1b developed, cell C1ba narrowed in apical, MP forked after nodal lines, MP1+2 and MP3+4 apically bifurcated into MP 1, MP 2, MP 3, MP 4 terminals, CuA 2-branched, the forking of ScP+RA and RP slightly basad of the forking of CuA 1 +CuA 2, the forking of Pcu+A 1 basad of center of clavus, with ten apical cells.

Legs. Legs brown, tibiae and tarsi yellowish, hind tibia with three lateral spines. Meta-tibiotarsal formula: 6/7/ 5.

Male genitalia. Anal segment ( Figs. 11, 12, 16 ) asymmetrical, in dorsal view sub-ovate, longer than broad, slender, slightly curving to right. Apical process with ventral margin excavated medially and with two convex productions. Pygofer ( Figs. 11, 12, 15 ) with lateral margin subtriangular in outline, asymmetrical, medioventral process absent, replaced by two small projections. Apical margin beset with many setae. In lateral view, pygofer with semicircular furrow-like sulcus in middle. Gonostyli ( Figs. 13, 14, 17, 18 ) in lateral view, thumb-shaped, swelling at apex. Gonostyli apically rounded with many setae along margin, shaft short. Between the apex and shaft, with a deep excavation, and the inner margin rounded with short setae. The basal dorso-lateral angle of dilated apex ( Emeljanov, 2001) with a tusk-like tooth. Aedeagus screw-shaped. Endosoma (= flagellum) convoluted with two sinuations, a right lateral one ( Fig. 17 ) and a left lateral one ( Fig. 18 ). Aedeagus with 7 sclerotized processes. In the right lateral view, endosoma with two long subparallel ribbon-like processes. Upper one (1) is long, with a flaky, sclerotized membrane at the apex of subapical dorsal margin. Apex slightly expanded and round, curving left-caudally. The lower one (2) shorter, with acute apex, directed left-caudally; basal portion (3) slightly outspread and round apically, curved left-laterally and slightly directed cephalad. In left lateral view, the basal level of left lateral sinuation of endosoma has two strong spines. The upper one (4) is long and slender at the basal portion, directed left-cephalad. The lower one (5) arises from midway along the dorsal margin, and stout and acute, with serrate apical margins, directed right-dorso-cephalad. Distal end of aedeagus with a big S-shaped process (6), tongue-like; ventral margin of process with serrate margin near distal 2/3 longitudinally extended. A scoop-like basiventral process (7) arises from the basal 1/3 of periandrium, directed cephalad.

Female genitalia. Unknown.

Material examined. Holotype: male, CHINA, Shaanxi Prov., Foping County, Yueba (33°55′N, 107°82′E), Alt 600–650m, 7.VII.2014, Rui-Kai Bai ( NWAFU); paratypes: 2 males, the same data as holotype.

Etymology. The specific epithet is named after the county in Shaanxi, the type locality.

Distribution: China (Shaanxi).

Host plants: Echinochloa crusgalli (L.) Beauv. ( Poaceae ).

Biology. I. fopingensis sp. nov. is known to occur in Foping county, which is on the southern slope of the middle Qingling Mountains. The specimens were collected near the rice fields in Yueba of Foping County at an elevation between 600m to 650m.
