description: Kodaianellissus gibbusis Kamran, Huang et Zhang, sp. nov.
Description: Length of male (from apex of head to tip of forewing, N=3) 5.5–6.0 mm.
Vertex and frons yellowish brown, anterior margin of frons black with small yellow spots, lateral margins yellowish with brown markings. Clypeus yellowish. Eyes greyish with tanned bands. Gena and antennae brown. Pronotum yellowish, mesonotum light brown. Abdomen dark brown dorsally. Tegmina, legs and longitudinal veins brown, cross veins yellowish.
Disc of vertex rectangular, 1.9 times wider than long, centrally and laterally carinate, two rounded markings near lateral margins. Posterior margins concave, anterior margins slightly curved in mid line at apex, lateral margins slightly transverse (Fig. 1D). Frons slightly globose, broader behind the eyes (Fig. 1C), median carina obvious, lateral margins slightly straight, concavely truncated behind eyes, obliquely narrow near clypeus (Fig. 1C). Clypeus with distinct brown transverse strips (Fig. 1C). Large compound eyes (Figs. 1C, D). Gena smooth, oblique in lateral view (Fig. 1B). Pronotum longer than vertex centrally, anterior margin convex, strongly carinate; posterior margin truncate, central carina yellowish, two black incisions near median carina on the disk (Fig. 1D). Mesonotum as long as pronotum, two brown spots near lateral margins and near base on each side of the disc, posterior one obviously smaller than apical one. Tegmina, distinctly longer than wide, ScP+R vein forked near base, ScP+RA vein long reaching ⅓ costal margin, RP vein very long, exceeding 1/3 of costa distad at outer margin of tegmina. MP vein bifurcate near basal ¼ long surpassing, MP 1+2 and MP 3+4 sinuate at apical margin. Cu forked at apical ⅓, Pcu and A 1 combine at basal half of clavus (Fig. 1E). Hind wing fully developed tri-lobed. Lobe Pcu-A 1 distinctly longer than wide; A 2 lobe narrower distad at ⅓ of Pcu-A 1, A 2 lobe simple, longer not forked (Fig. 1F). Hind tibiae with two lateral spines, spinal formula 8-7-2.
Male genitalia. Anal segment in dorsal view (Fig. 1H) rectangular, longer than wide, laterally straight, slightly convex at basal half, anal foramen short, located in basal half (Fig. 1H). Anal tube in lateral view long, convex at posterior ⅓, ventral margins slightly prominent (Fig. 1G). Pygofer in lateral view, long and slender with parallel anterior and posterior margins (Fig. 1G). Genital styles rectangular, widest at basal ⅓, caudoventrally rectangular slightly curved near base of capitilum at posterior margin, dorsolaterally provided with hump-like processes near base of capitulum (Fig. 1J). Capitilum very long, tubular, apically sclerotized slightly bent directed anteriorly, posterior margin with lobe-like process (Fig. 1J). Aedeagus in lateral view elevated at both sides, divided into two lobes, dorsolateral lobe slightly membranous in apical portion, centrally convex. Sharp sclerotized spines directed dorsad on each side of ventral apical part (Fig. 1K). In ventral view, periandrium is long U-shaped, somewhat symmetrical, dorsolateral margins twisted in distal half, pair of long hooks arising in distal half directed downwards (Fig. 1I).
Type materials: Holotype: ♂ Rawlakot, Azad Jammu & Kashmir, Pakistan, 33°51’32.18”N, 73° 45’34.93”E, 1628 m, 14-vii-2018, coll. Kamran Sohail. Paratypes 2♂♂, same data as holotype.
Female: Unknown.
Etymology: Latin word “ gibbus ” means hump, referring to hump-like processes near base of capitilum on dorsolateral side.
Host plants: Unknown.
Diagnosis: Kodaianellissus gibbusis sp. nov. can be differentiated from K. intorqueus by characters mentioned in the key.
Remarks: Phylogenetic analyses of 5 species of Hemisphaeriinae, including two out-groups (Gelastyrella litaoensis and Darwallia barbata), based on ML and BI analyses of nucleotide sequence data of two genes, yielded almost same topologies with strong support (Fig. 2). The molecular analyses (Fig. 2) with morphological characters indicates its placement into the Kodaianellissus.
