Hishimonus nauniensis sp. nov. Meshram

( Figs. 1–5 & 16–23 )

Head, pronotum and scutellum lemon yellow with pale brown central area. Forewings ivory white with few brown spots between veins; median spot well defined, pale brown with dark brown spots, narrow, discontinuous anterior margin, posterior margin with dark brown spot at wing margin. Legs in male, pale ochraceous; in female, femora dark brown; bases of setae on tibiae in both sexes dark brown ( Figs. 16–18 ).

Head including eyes 1.2x width of pronotum. Head broadly rounded in front, crown length 0.5x shorter than width between eyes. Face length 0.6x width of face; anterior margin of pronotum not extending beyond eyes. Anteclypeus apically exceeding facial margin ( Fig. 18 ). Frontoclypeus longer than wide; frontal suture, terminating laterad of ocelli. Ocelli near anterior margin, very close to eye, distance between eyes and ocelii 0.5x ocellar diameter. Antennae situated somewhat at level with the middle margin of eyes in facial view ( Fig. 18 ). Pronotum length 0.4x as long as wide and 0.9x length of scutellum. Forewings with claval veins joined by cross vein at mid length; inner subapical cell open basally, outer subapical cell elongate with ends transverse; appendix small ( Fig. 17 ).

Male genitalia: Pygofer in lateral view longer than height, posterior margin conically rounded, macrosetae confined to posterior half ( Figs. 4 & 19 ). Valve 1.6x as wide at base as long ( Figs. 5 & 23 ). Subgenital plates broadly rounded at base, terminal fingerlike process about 3.5 times shorter than total length, long hairlike setae along lateral margin, terminal process with short microsetae ( Figs. 5 & 23 ). Style approximately 2.5x as long as wide at base; preapical lobe well developed with few hairlike setae, apophysis blunt, slightly directed laterally. Stem of connective slender, longer than arms ( Figs. 3 & 20 ). Aedeagal shaft narrowed near mid length to slender anteriorly directed apex, triangular in lateral view, gonopore subapical ( Figs. 1–2 & 21–22 ).

Measurements. Male 3.4–3.7 mm long, 1.1–1.20 mm wide across eyes.

Material examined. HOLOTYPE ♂, INDIA: Himachal Pradesh: Solan: Nauni 1502 m, 30.8625° N, 77.1679° E, 10.vi.2013, at light, Shashank ( NPC).

Remarks. Hishimonus nauniensis sp.nov. closely resembles H. concavus Knight but differs in (characters H. concavus in parentheses): Head, pronotum, and scutellum lemon yellow with pale brown central area (head and pronotum yellow, scutellum with pale brown central area, lateral margins lemon yellow with two faint fuscous spots near base and another before apex); valve 1.6x as wide at base as long (valve about twice as wide at base as long). stem of connective slender, longer than arms (stem of connective slender, as long as arms). aedeagal shaft evenly tapered in lateral view (shaft strongly abruptly tapered in lateral view beyond triangular expansion and concavely excavated).
