Ansifera malayensis sp. n.

(Fig. 2 A-D)

Diagnosis:

Males are characterized by the following features in combination: the antennal translucent sensilla are looped (Fig. 2C), the eye bridge is throughout of equal length (Fig. 2A), the ventral emargination of the gonocoxites is shallow (Fig. 2D), and the gonostyli are comparatively slender (Fig. 2D).

Description:

Male. Body length: 1.0- 1.1 mm. Head: Fig. 2A. Postfrons usually asetose, exceptionally with 1 seta. Eye bridge 4 ommatidia long. Postocular bristles 1-2. Neck and node of fourth antennal flagellomere subequal in length; node with 1 complete and 2 incomplete crenulate whorls, 1- 2 looped translucent sensilla (Fig. 2C). Maxillary palpus comparatively long, first segment not swollen, apical segment longest of all, sparsely setose or asetose (Fig. 2B).

Wing: Costal break indistinct or missing. ApicR1 1.5-2.5 times the length of Rs.

Preabdomen: Segment 2 with no tergal and few sternal setae. Terga 3-4 only with lateral setae, terga 5-8 with lateral and dorsal setae. Terminalia: Fig. 2D. Setae on tg9 sparse. Ventral emargina-

tion of gonocoxites shallow, dorsal transverse bridge projecting beyond ventrobasal margin, the latter reinforced. Gonostylus subcylindrical, comparatively slender. Ejaculatory apodeme longer than tegmen, apical extension large, funnel-shaped. Tegmen slightly tapered toward apex, the latter membranous, blunt. Cerci projecting far beyond tg9.

Female and immature stages. Unknown.

Distribution and phenology:

Specimens come from two primary rainforests in the Selangor and Pahang Provinces, West Malaysia. The collecting sites are located at altitudes of 250 and 1000 m above sea level. Specimens were collected over rotten wood or elsewhere in the forest interior and along forest edges.

Etymology: The name refers to Malaysia, where all the known specimens were collected.

Types: Holotype: Male, West Malaysia, Selangor, Ulu Gombak, near University of Malaya Field Studies Centre, in evergreen rainforest, 250 m, 24 Feb.-14 March 1997, by Malaise trap, H. HIPPA, M.
