Jilinga Ghauri, 1974:551; Webb & Heller 1990:8; Xing et Li, 2012:49 Type species: Deltocephalus darjilingensis Distant, 1918
Description. Overall coloration dirty yellow to brownish yellow with darker markings. Vertex with pair of oblique streaks on anterior margin. Face mostly dirty yellow with paired brown horizontal arcs on frontoclypeus. Pronotum with four or six dirty yellow or brownish yellow longitudinal bands. Forewing semiopaque, veins white, cells bordered with dark brown. Abdomen brownish yellow, with draker markings. Legs mostly pale, with or without small, symmetrically arranged dark maculae.
Head slightly wider or subequal to pronotum. Vertex flat, distance between eyes slightly wider than medial length, anterior margin distinctly produced in dorsal view, rounded to face, glabrous medially, finely granulose laterally; ocellus small, separated from eye by approximately one ocellar diameter on anterior margin. Face relatively flat, shagreen, width equal to length; frontoclypeus relatively narrow; clypeal suture usually welldeveloped, slightly arcuate; eye emarginate adjacent to antenna; antenna longer than width of head; gena obtusely emarginate below eye; lorum semicircular, narrower than anteclypeus, well separated from lateral and ventral margins of face; anteclypeus flat, slightly to moderately tapered from base to apex, apex truncate and even with lower margin of gena. Pronotum medially longer than head, with anterior margin roundly produced, posterior margin approximate straight, lateral margin very short. Scutellum triangular, shorter than length of pronotum, suture curved. Forewing slightly longer than abdomen, with four apical cells and three subapical cells, inner subapical cell closed; outer subapical cell short, with base and apex tapered, usually extended to costal margin; appendix moderately broad, extended to second apical cell. Hindwing slightly shorter than forewing, veins Pcu and A1 confluent from the base of wing to middle of vein A1, half of A1 to margin of wing weak.
Profemur dorsal margin with AD1 and PD1 setae long; AM1 seta near ventral margin of femur; intercalary row with 9 setae; row AV with 3 short, stout macrosetae and numerous thin, hair-like setae; AV1 seta similar to intercalary row setae. Protibia with 4 long fine setae in row AD and 15 macrosetae in row PD. Metafemur apical setae 2+2+1. Metatibia flattened and thin, row PV with one row of numerous gradually longer setae, row AD with 10 macrosetae interspersed by zero to four small stout setae, row PD with 10 macrosetae and 9 shorter, stout setae between macrosetae. Metatarsomere I not expanded apically, with five platellae.
Male. Abdominal apodemes not well developed, with small, membranous lobes. Anal tube long, incised about 2/3 into pygofer, tergite X produced ventrally with well-developed appendages. Pygofer in lateral view equal to or longer than plate, posterior margin produced into bluntly rounded lobe with many long macrosetae, caudoventral margin with or without medial process. Valve triangular, rounded or acute at apex. Subgenital plate long, triangular, widest at base and tapered to rounded apex, median margin concave, with sublateral row of macrosetae. Style with apophysis linear or transverse, wider or narrower than width across preapical lobe, heavily sclerotized; basal part transverse, with transverse basal medial and lateral lobes short, robust. Connective elongate and loop-shaped, stem absent, arms tapered posteriorly and fused; articulated with preatruim of aedeagus. Aedeagus in lateral view with tapering shaft, dorsal apodeme short, articulated with well-developed, symmetrical dorsal connective; shaft flattened dorsoventrally and curved dorsally, lateral margins serrated in ventral view; gonopore ventral, elongate, apical.
Female with seventh sternite basally transversely rectangular, distally produced into rounded lobe. Female pygofer with numerous macrosetae on posterior margin. First valvula lanceolate, with reticulate sculpture dorsally. Second valvula narrowly blade-like, with fine dorsal denticulation on posterior slender part. Third valvula with expanded apical region.
Distribution. China, India, Pakistan, Nepal.
Remarks. The genus Jilinga has a complex and diversely shaped dorsal connective which distinguishes the genus from other Oriental genera of Paralimnini. Species of this genus can be distinguished by differences in the shape of the aedeagus, dorsal connective and style. The discovery of new species on Taibai Mountain greatly expands the known range to the north of the previously known range of the genus.
