Jilinga Ghauri 

Jilinga Ghauri, 1974: 51  ; Webb & Heller 1990: 8; Xing et al, 2012: 49

Type species: Deltocephalus darjilingensis Distant, 1918 

Coloration stramineous to yellowish brown with dark spots. Crown with yellowish brown to dark oblique streaks at anterior margin. Frontoclypeus mostly black with paired thin, pale arcs. Forewing with veins prominent, white in colour; cells light brown, bordered with dark brown. Legs brownish yellow or pale, mostly with symmetrically arranged dark spots.

Head wider than pronotum, anteriorly triangularly produced. Crown flat, median length slightly shorter than breadth between eyes. Eye with distinct notch adjacent to antennal base. Ocelli small, separated from eye by approximately one ocellar diameter. Antennae arising near lower corner of eye, length greater than width of head. Anteclypeus tapered. Lorum well separated from genal margin. Pronotum with 4 to 6 yellowish longitudinal bands, lateral margins short, round, posterior margin slightly convex. Forewing slightly exceeding the abdomen, slightly longer than hind wing, with four apical and three subapical cells; outer subapical cell extended to costal margin; inner subapical cell closed basally; branches of vein R slightly reflexed; appendix narrow, extended to second apical cell. Profemur dorsal margin with AD1 and PD1 setae long; seta AM1 close to ventral margin; 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 1 apical AD macroseta and 4 macrosetae in row PD. Metafemur apical setae 2+2+1. Metatibia flattened and thin, row PV with one row of numerous setae gradually increasing in length, 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 with 4-5 platellae, without apical expansion.

Male pygofer well sclerotized dorsally, only weakly incised basad of anal tube, side quadrate in lateral view, slightly longer than wide, with macrosetae scattered over distal half, with pair of sclerotized processes arising from inner membrane and partially enclosing aedeagal shaft. Anal tube short, membranous basally, with long paired or partially fused ventral process arising from sclerotized distal ring, extended ventrad and contacting aedeagus and inner pygofer processes when retracted. Valve sharply triangular, nearly as long as subgenital plate. Subgenital plate broad at base, tapering towards apex, lateral margin strongly convex basally, strongly concave distally, with row of few macrosetae laterally in basal half. Style with apophysis varying from digiti form to foot-like, transverse basal medial and lateral lobes short. Connective loop-shaped with no stem, arms fused posteriorly, articulated with aedeagus. Aedeagal shaft curved dorsally, with shaft depressed, lateral margins serrate, gonopore apical, dorsal apodeme articulated with well sclerotized dorsal connective.

Distribution. Pakistan, China, India, Nepal.

Remarks. Jilinga Ghauri  can be easily distinguished from other members of the tribe Paralimnini  by the welldeveloped dorsal connective, the presence of sclerotized processes arising from the inner pygofer membrane, the depressed, laterally serrate aedeagal shaft, and the unique ventral processes of the anal tube. Species of this genus can be differentiated from one another by the shape of the subgenital plate, style, anal tube process, pygofer processes and aedeagus.
