Paramedetera digitata , new species

( Figs. 11-12 )

Material examined. – Holotype - male: SINGAPORE: Nee Soon , 9 Mar.2005, swamp forest (25004, coll. P. Grootaert, Si 384; ZRC).

Description. – Male. Body length: 1.50 mm; wing length: 1.25 mm. Ocellar and vertical bristles brown. Palpi black with a black apical bristle. Four dorsocentrals, anterior 2 shorter than posterior 2. All bristles on scutum dark brown. Propleural bristle long, pale brown. Halter greyish-brown. Squama brown with long pale cilia. Legs yellowish-brown, but all coxae and femora brown. Tibiae and tarsi yellowish, 4 th and 5 th tarsomeres of all legs dark brown.

LI: Length of femur, tibia and tarsomeres (in mm): 0.35: 0.35: 0.19: 0.07: 0.06: 0.04: 0.06.

LII: Length of femur, tibia and tarsomeres (in mm): 0.38: 0.42: 0.21: 0.10: 0.07: 0.04: 0.06.

LIII: Length of femur, tibia and tarsomeres (in mm): 0.42: 0.42: 0.12: 0.15: 0.07: 0.06: 0.06.

Hypopygium ( Figs. 11-12 ) rather elongate. Aedeagus orange, with a downwards pointed tip. Hypandrium triangular, a little sunk between the rounded lobes of the epandrium that bears the basal epandrial seta. Epandrial setae all short, none on a tubercle. Lateral to the epandrial setae is a black finger-like projection of the epandrium. Dorsal surstylus with a curved tip, large and wide in lateral view (not straight and stalk-like as in the other species).

Female unknown.

Etymology. – The name digitata refers to the finger-like projections on the epandrium dorsad of the epandrial setae. This is so far a unique character in Paramedetera .

Differential diagnosis. – A finger-like projection lateral to the epandrial setae is not present in other Paramedetera species.
