Specimens examined.

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).

Diagnosis.

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).

Description.

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 3rd 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).

Measurements.

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

Remarks.

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).

Etymology.

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