Gladkara albida Dworakowska, 1995

Dorsum beige or white. Color pattern absent or brown. Head narrower than pronotum, crown produced in midline anteriorly. Face convex. Pronotum with large impressions medially. Forewing with AA vein prominent, all known species with dark patch in 3^rd apical cell except the type species. Hind wing venation usual for Erythroneurini.

Male 2S abdominal apodemes broad, reaching 3S posterior margin.

Genital capsule cylindrical, slightly laterally compressed. Pygofer side broad, with caudal margin oval to square, with numerous sparse long fine setae, with or without enlarged macrosetae scattered at ventrolateral angle; dorsal appendage moveably articulated to the lobe, simple or bifurcate far from base, extended to pygofer apex or extended beyond pygofer apex; ventral appendage absent; segment X appendage present. Subgenital plate lamellate, with small latero-basal articulation with style, about 4–5 macrosetae in single or double row, setae of basal group in an oblique or longitudinal row, intergrading into marginal microsetae. Style long and slim, apical part tapering, smooth or adorned with sculpture; preapical lobe small. Connective lamellate, lateral arms long, stem reduced and central lobe desclerotized to various degree. Aedeagus with or without processes, aedeagal shaft tubular; dorsal apodeme with distinct V-shaped ligaments, connected to anal tube and/or pygofer dorsal appendages; preatrium about as long as or shorter than shaft; gonopore apical or subapical on ventral surface.

Distribution. India; Brunei; Vietnam and Thailand.

Holotype: ♂, THAILAND, Surat Thani, Khao Sok NP Klong Morg Unit, 8°53.725'N, 98°39.025'E, 87 m, Malaise trap, 16-23.xii.2008, coll. Pongphan (QSBG). Paratypes: 3♀♀, same data as holotype (INHS, SKS).

This species has its own salient characteristics as follows: pygofer with a bifurcate dorsal appendage (Fig. 10), segment X appendage twisted medially and hook-like apically (Fig. 11); style extremely elongated, with many cellular sculpturing apically (Fig. 14); aedeagus with long and tubular shaft, and a single short tooth-like process arising from preatrium (Fig. 18).

Ground color pale beige. Eyes grey (Figs 1–3). Face pale beige; apex of frontoclypeus slightly darker in male; coloration extremely pale in female (Figs 4, 8). Pronotum pale anterolaterally, blackish beige medially and posteriorly (Figs 1, 3). Scutellum beige, with prominent scutellar suture (Figs 1, 3). Fore wing beige, with an irregular big dark brown spot at 3^rd apical cell (Figs 1, 2).

Male abdominal apodemes broad, extending to the hind margin of third sternite (Fig. 9).

Male genitalia. Pygofer with dorsal appendage movably articulated (Fig. 10), segment X appendage elongated, twisted medially, and hook-like apically (Figs 11, 12). Pygofer lobe broadened, with two long fine setae arising from dorso-caudal margin and several long fine setae scattered near caudal margin medially (Fig. 10). Subgenital plate solid, much longer than hind margin of pygofer lobe, with four macrosetae on lateral surface and numerous stout setae along upper margin from sub-base to apex of plate, several microsetae scattered apically (Figs 10, 13). Style extremely elongated, with many cellular sculptures apically; preapical lobe small (Figs 14, 16). Connective V-shaped with lateral arms long and slim, widely divergent; stem short; central lobe absent (Fig. 15). Aedeagus with a single short toothlike process arising from preatrium; preatrium little shorter than length of shaft in lateral view, expanded in ventral view; shaft slender, tubular, slightly tapered distally in lateral view; gonopore apical (Figs 17, 18).

Body length, male 3.7 mm; females 3.5–3.6 mm.

This species is similar to G. lisiogon Dworakowska, 1995 from Brunei (Ulu Temburong) in the form of the aedeagus, but differs in having the dorsal pygofer appendage bifurcate apically (Fig. 12); the single short tooth-like process arising from aedeagal preatrium (Fig. 18); and the aedeagus dorsal apodeme not strongly expanded in caudal view (Fig. 18).

The specific name is derived from a part of the type locality name in which all examined species were collected.
