Type material.

Holotype male, INDIA: Karnataka: Shimoga district, Someshwari Wildlife Sanctuary, 10 km W Agumbe, 13°28′24″N; 75°00′40″E, alt. 372 ft, early successional, wet evergreen forest, 22.ix.2005, C. R. Bartlett leg. ( UDCC).


Orthopagus bartletti  sp. n. can be separated from all other Orthopagus  species by the very short head, hardly produced in front of eyes; the forewings with a brownish streak along nodal line connecting the pterostigmal area with the distal sublunate streak; the dorso-posterior margin of the male pygofer with a large and broad process forming two distinct angles; the robust male segment X; and the lobes of the phallobase muricate apically.


Measurements (1 male). Body length (from apex of head to tip of forewings): 11.5 mm; head length (from apex of cephalic process to base of eyes): 1.2 mm; head width (including eyes): 1.5 mm; forewing length: 9.6 mm.

Coloration (Fig. 2 A–B). General colour brownish ochraceous marked with dark brown on dorsum. Head greenish ochraceous, vertex with basal corners, a pair of round patches in basal third, and apical diamond-shaped spot dark brown (Fig. 4A); frons with median area between intermediate carinae extensively dark brown anteriorly and with series of small pale fuscous spots along intermediate and lateral carinae and narrow ivory white band basally (Fig. 4C). Clypeus ivory white, with two small spots at base and apex dark brown. Compound eyes fuscous with posterior margin ochraceous; ocelli purplish-red. Pronotum brownish ochraceous, median carina, apical marginal areas of ventral lobes, and posterior lateral angles ivory white. Mesonotum brownish ochraceous (Fig. 4A). Forewings hyaline, veins ochraceous, pterostigmal area, a streak along nodal line, and a wide sublunate streak on distal third dull ochraceous; posterior (claval) margin broadly faintly brown (Fig. 3A). Hind wings hyaline, veins and an apical spot dull ochraceous. Legs pale brown; fore femora subapically and hind tibiae at base and apex (including lateral and apical spines) blackish. Abdomen dorsally and ventrally brownish ochraceous.

Structure. Head (Fig. 4 A–C) very short, cephalic process practically absent. Vertex (Fig. 4A) with ratio of length at midline to width between eyes 1.4. Frons with base slightly inflated anteriad in dorsal view (Fig. 4A), with transition to vertex broadly rounded in lateral view (Fig. 4B); in ventral view, frons with ratio of length at midline to maximum width 2.2; median carina more or less obscure at base (Fig. 4C).

Male genitalia. Pygofer, in lateral view, with dorso-posterior margin forming a large, broad, biangular lobe (Fig. 4E); in ventral view (Fig. 4F) much longer than in dorsal view (Fig. 4D) with ratio of ventral to dorsal width about 3.4. Gonostyles (Fig. 4E, F) elongate, relatively narrow in basal half, with strongly sinuate dorsal margin medially. Aedeagus (Fig. 4 G–I) with endosomal processes relatively short and robust, without distinct minute superficial spines, and directed laterad; phallobase with a pair of large, elongate, thumb-like ventral lobes, curved dorso-posteriad and muricate apically (Fig. 4 G–H); and a pair of shorter lateral lobes, directed posteriad (Fig. 4H). Segment X, in lateral view, relatively short and robust, with ventral margin gradually widening from base to broadly truncate apex (Fig. 4E); in dorsal view broad, broadest medially, with ratio of length to maximum width 1.1 (Fig. 4D).

Female genitalia unknown.


The new species is named after Dr. Charles R. Bartlett, collector of the type specimen and curator of the insect collection at the Department of Entomology and Wildlife Ecology, University of Delaware, USA, in recognition of his kindest help and support to the first author when he visited UDCC in 2017. The species name is to be treated as a noun in genitive case.


So far only known from southwestern India (Fig. 11).
