Anal tube membranous. Subgenital plate, in lateral view (Fig. 44G ), reaching pygofer apex; in ventral view (Fig. 44H ), elongated, 4.7 × longer than wide, with short setae on outer half; lateral margins approximately parallel; apex rounded. Connective (Fig. 44I ) D-shaped; dorsal keel reduced; stem short and wide with lateral margins weakly sclerotized. Style, in dorsal view (Fig. 44J ), with external lobe reduced; in lateral view (Fig. 44K ), blade thin and sinuous, with width approximately constant; ventral margin with apical third serrated; apex tapered and curved dorsally, forming a small acute dorsal process. Aedeagus (Fig. 44L, M ) preatrium developed, forming pair of processes extended ventrally; dorsal apodeme developed, dorsal margin straight, lateral margins produced ventrolaterally; apodemal process elongated and curved anterad, slightly wider basally and narrowed subapically, apex enlarged and truncated, with small acute process on outer margin, directed ventrally; shaft J-shaped, approximately cylindrical, symmetrical, distal portion straight, slightly enlarged towards apex; apex with two pairs of short processes, arising on anterior margin, directed ventrally; outer pair about twice as long as the inner pair.

Female terminalia.

Sternite VII (Fig. 45A ) 1.6 × wider than long; posterolateral angles produced as far as posterior margin; posterior margin slightly excavated laterad of broad median lobe weakly emarginated. Pygofer (Fig. 45A, B ) 1.9 × longer than maximum height, 2.6 × longer than sternite VII length; macrosetae distributed on ventral half and apex; apex oblique truncated. First valvifer (Fig. 45C ) subtriangular, 1.5 × longer than wide, anterior margin slightly rounded, dorsal margin straight, posterior margin rounded. First valvula (Fig. 45C ) 5.1 × longer than wide, slightly wider at median third; dorsal sculptured area strigate; dorsal margin sinuous at apical third; apex (Fig. 45D ) strongly tapered and acute. Second valvula (Fig. 45E, F ) 5.3 × longer than wide, slightly wider at median third; dorsal protuberance truncated, located at half length of blade; dorsal margin with small, rounded teeth on apical third; ventral margin with denticles apically; apex abruptly narrowed and subacute. Second valvifer (Fig. 45G ) 3.2 × longer than wide. Gonoplac (Fig. 45G ) 3.8 × longer than wide; dorsoapical and ventroapical margins convergent apically; dorsoapical margin straight, with 1\3 length of blade; ventral margin evenly rounded; external surface with dentiform cuticular projections; apex (Fig. 45H ) subacute.

Etymology.

The species name is in reference to the elongated shape of body.
