Figs 1–3
Diagnosis
This species can be separated from all other species of Birdantis by the following combination of characters:
(1) frons entirely yellow-brown without lines or spots (Fig. 1D)
(2) bulge between frons and vertex coloured as vertex (Fig. 1B)
(3) abdomen mostly orange dorsally (Fig. 1A) and ventrally (Fig. 1C)
(4) tegmina opaque on basal half and infuscate on distal half (Fig. 1A)
(5) hind wings largely smoky, but not hyaline or with a large black area (Fig. 1A)
Etymology
This species is dedicated to Mr Edy Bhaskara (Indonesia) in acknowledgment of his generous contribution to the present work.

Description
MEASUREMENTS AND RATIOS. LT: ♂ (n = 2): 19.0 mm (18.9–19.2); ♀ (n = 6): 21 mm (20.4–21.2). LTg/BTg = 3.45; BV/LV = 4.45; LF/BF = 0.83.
HEAD (Fig. 1B, D, F). Pale yellow-brown with small black marking at posterior angles of vertex, a larger black marking behind eyes, median portion of clypeus darker and more reddish, with a yellowish central line, labium pale yellow-brown turning to brown on two apical segments and antennae brown. Vertex with deep transverse groove and all margins carinate, shorter in middle than on sides. Frons finely wrinkled, with two smooth longitudinal carinae slightly diverging towards dorsum and a slight longitudinal groove on each side between carina and lateral margin; broadest near base, above clypeus; convex in dorsal view and with dorsal margin rounded in perpendicular view; bulge between frons and vertex only visible dorsally. Ocelli under eyes. Antennae with scape short and cylindrical, and pedicel inflated and reniform. Clypeus narrower than frons, reaching apex of procoxae. Labium with penultimate segment surpassing hind coxae (Fig. 1C).
THORAX (Fig. 1B, D, F). Pronotum pale yellow-brown, with median carina and impressed point on each side of latter; small back-brown spot on each side of disc, short black-brown line on median carina on anterior half and brown marking behind eye. Mesonotum dark brown, with median and peridiscal carinae well marked, concolorous; wrinkled in the area limited by peridiscal carinae; mesothoracic sternites pale yellow-brown. Metathoracic sternites dark brown. Tegulae yellow-brown.
TEGMINA (Fig. 1A, C). Elongate, broader at nodal line and acutely rounded apically. Corium and clavus with numerous cross-veins, brown variegated with darker patches and a blackish line along external side of vein Pc+CP; veins and cross-veins yellow. Membrane smoky, roundly extending inside corium medially and with brown spots on distal part and brown markings on nodal line; veins yellow turning to black-brown after nodal line.
HIND WINGS (Fig. 1A, C). Light smoky brown with veins black-brown, darker at basal angle and with anal area with a grey hue and cross-veins whitish; maximal breadth near base; slightly broader than tegmina.
LEGS (Fig. 1A, C). Elongate and slender. Pale yellow-brown with apex of pro- and mesofemora black distally; pro- and mesotarsi black; metatibiae brown apically, with six lateral spines and six apical spines, all spines dark brown apically; metatarsi with first tarsomere yellow-brown, brown apically and with nine apical spines ventrally, second and third tarsomeres dark brown, the second one with eight apical spines ventrally. Metatibiotarsal formula: (6) 6/9/8.
Male genitalia
Pygofer higher than long, about 1.4 times as high as maximum length, longer ventrally and abruptly narrowing on dorsal ¼ in lateral view; dorsal margin of pygofer oblique in lateral view (Fig. 2A). Anal tube elongate, about 2.1 times as long as maximum breadth, curved ventrally near base; lateral margins subparallel, only slightly sinuate and with narrowest portion at basal ¼; apical margin strongly emarginate in dorsal view, acutely rounded in lateral view (Fig. 2A–B). Gonostyli subtriangular in lateral view, with posterior margin rounded; anterodorsal margin emarginate after lateral process; lateral process laminate, directed laterally and apically pointed, with apical point directed lateroventrally (Fig. 2A–B). Aedeagus mostly membranous; phallobase with two ventral, elongate processes; aedeagus s. str. strongly reduced but endosoma well developed with six membranous digitiform processes, with posteroventral left process with secondary process directed centrally (Fig. 2C–F).
Distribution
Larat Island (Fig. 3).
