Orthopagus bartletti Song, Malenovsky & Deckert sp. n. Figs 2A-B View Figure 2 , 3A View Figure 3 , 4A-I View Figure 4

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).

Diagnosis.

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.

Description.

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. 2A-B View Figure 2 ). 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 View Figure 4 ); 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 View Figure 4 ). 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 View Figure 4 ). 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 View Figure 3 ). 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. 4A-C View Figure 4 ) very short, cephalic process practically absent. Vertex (Fig. 4A View Figure 4 ) with ratio of length at midline to width between eyes 1.4. Frons with base slightly inflated anteriad in dorsal view (Fig. 4A View Figure 4 ), with transition to vertex broadly rounded in lateral view (Fig. 4B View Figure 4 ); 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 View Figure 4 ).

Male genitalia. Pygofer, in lateral view, with dorso-posterior margin forming a large, broad, biangular lobe (Fig. 4E View Figure 4 ); in ventral view (Fig. 4F View Figure 4 ) much longer than in dorsal view (Fig. 4D View Figure 4 ) with ratio of ventral to dorsal width about 3.4. Gonostyles (Fig. 4E, F View Figure 4 ) elongate, relatively narrow in basal half, with strongly sinuate dorsal margin medially. Aedeagus (Fig. 4G-I View Figure 4 ) 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. 4G-H View Figure 4 ); and a pair of shorter lateral lobes, directed posteriad (Fig. 4H View Figure 4 ). Segment X, in lateral view, relatively short and robust, with ventral margin gradually widening from base to broadly truncate apex (Fig. 4E View Figure 4 ); in dorsal view broad, broadest medially, with ratio of length to maximum width 1.1 (Fig. 4D View Figure 4 ).

Female genitalia unknown.

Etymology.

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.

Distribution.

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