Paramedetera micropyga , new species

( Figs. 1-3 )

Material examined. – Holotype - male: SINGAPORE: Nee Soon , 4 Dec.2002, swamp forest (22054, coll. P. Grootaert, Si 303; ZRC).

Paratypes – 1 male, Nee Soon, 25 Nov.2003 (23086; coll. P. Grootaert, Si201); 1 male, Nee Soon, 3 Dec.2003 (23102, coll. P. Grootaert, Si 218; coll. RBINS) .

Description. – Male. Body length: 1.60 mm; wing length: 1.50 mm. Ocellar and vertical bristles pale yellowish. Palp black with a black apical bristle. Four dorsocentrals, preceded by a short bristle (about a fifth length of anterior dc), 2 anterior dc shorter than posterior 2. All bristles on scutum brownish. Scutellars pale brown. Propleural bristle long, pale. Halter greyish-brown. Squama with a brown border, bearing 6 pale yellowish cilia.

Legs yellowish-brown, but all coxae and femora brown. Tibiae and tarsi paler, yellowish, 5 th tarsomeres of all legs dark brown.

LI: Length of femur, tibia and tarsomeres (in mm): 0.42: 0.40: 0.21: 0.12: 0.08: 0.06: 0.07.

LII: Length of femur, tibia and tarsomeres (in mm): 0.52: 0.55: 0.31: 0.17: 0.12: 0.07: 0.06.

LIII: Length of femur, tibia and tarsomeres (in mm): 0.56: 0.56: 0.21: 0.22: 0.13: 0.07: 0.06.

Hypopygium ( Figs. 1, 3 ). Aedeagus ( Fig. 2 ) rather small, hyaline, with a bird’s headlike tip, bearing a sharply pointed tip. Hypandrium triangular, a little erect, with a elongated tip. Median epandrial bristle the longest, on a long tubercle. Lateral pairs of epandrial setae also on a tubercle.

Female unknown.

Etymology. – The name micropyge refers to the rather small aedeagus.

Differential diagnosis. – The aedeagus is rather small and the tips of the aedeagal wings are pointed in lateral view. The inner rim of the wings does not bear a tooth-like projection, that distinguishes it from P. jixiuensis and P. borneensis .
