Watara longiprocessa sp. nov.

(Figs 5–8, 9–12, 23–31)

Description. Ground color pale beige. Eyes grey (Figs 6–8). Face pale beige; middle and lower part of frontclypeus slightly darker (Fig. 8). Pronotum pale anterolaterally, with two brown spots near anterior margin; blackish beige medially and whitish posteriorly (Figs 5, 7, 9, 11). Scutellum beige, with light orange tint; basal triangles dark brown. Two central brown patches situated posterad of scutellar suture and between basal triangles (Figs 5, 7, 9, 11). Fore wing pale, with rounded dark brown patch at brochosome field basad and several other orange or brownish patches on surface (Figs 5, 9).

Male abdominal apodemes broad, extending to middle part of 5th sternite (Fig. 23).

Male genitalia. Pygofer with dorsal appendage movably articulated (Fig. 24). Pygofer lobe with one dorsal macroseta and 6 grouped long macrosetae at baso-ventral angle (Fig. 24). Pygofer dorsal appendage short, hooklike apically (Fig. 24). Subgenital plate with 4 macrosetae on lateral surface in a row and several microsetae scattered apically (Figs 24, 25). Style with preapical lobe quite small in lateral view (Fig. 27). Connective Y-shaped, central lobe absent (Fig. 29). Aedeagus with pair of long process arising from base of shaft; preatrium very short and dorsal apodeme slightly expanded in lateral view (Figs 30, 31).

Measurement. Body length, male 2.3–2.4 mm.

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: 9♂♂, same data as holotype (INHS, SKS).

Remarks. This species is very similar to W. cordata Zhang & Yang (2011) from Yunnan (China) in external morphological characteristics, but differs in having the paired long processes arising from base of aedeagal shaft (Figs 30, 31); the aedeagus dorsal apodeme slightly expanded in lateral view and the preatrium strongly reduced (Fig. 30).

Etymology. The specific name is derived from the Latin prefix “longi-” and Latin word “processus”, referring to the long basal processes of the aedeagus shaft (Figs 30, 31).
