Eudorylas luteopilus ( Hardy, 1962)

( Figs 25F–L )

Pipunculus (Pipunculus) luteopilus Hardy 1962: 250 .

Diagnosis : T6 with an S-shaped process dorsally. Surstyli asymmetrical, OS with a projection towards IS; epandrium enlarged, as long as ST 8 in dorsal view, with a projection on the left side in ventral view (visible also in right lateral view); no m.a.; phallic guide broad, with an unsclerotized lobe towards SS in ventral view and with a membranous part visible in lateral view; ejaculatory apodeme fan shaped; sperm pump round, with two distal tails.

Type material: Madagascar: 1♂, HT, [East] Madagascar, Tam., Perinet , 10.IV.58, F.Keiser; 1♀, AT, ibid., 23.IX.58 (both NHMB).

Male

Head. Third antennal segment acuminate; yellow. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose; eyes touching for distance equal to 2 times ocellar triangle. Occiput, lower half silvery pollinose, upper half subshining brown-black.

Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) brownish pollinose; silvery from the side. Scutellum brown, with 5–6 pairs of hairs as long as width of f3 at base. Dorsocentral hairs weakly developed, notopleural depression with several pale hairs. Halter yellow-brown.

Legs. Entirely yellow. Ventroapical row of 5–6 spines on f2; spines missing on f1,3. Subapical (distal) spines on first four tibiae present. No anteromedial hairs on 3rd tibia. Hind trochanter without hairs or spines on ventral side. Pulvilli shorter than last tarsal segment.

Wing. Fourth costal section as long as third costal section. Cross-vein R-M just beyond ¼ of discal cell. Pterostigma coloured on distal 3/4. Hairs on tegula missing.

Abdomen. Viewed obliquely from front tergites subshining black entirely. Hairs dispersed, short and pale. Laterally 4 dark bristles on first tergite. Postabdomen in dorsal view: edge of EP visible; T5 as long as ST8. Genitalia without dissection: no m.a., EP and SS yellow, EP enlarged.

Genitalia. T6 with an S-shaped process dorsally ( Fig. 25I ). Surstyli asymmetrical, OS with a projection towards IS; epandrium enlarged, as long as ST 8 in dorsal view, with a projection on the left side in ventral view (visible also in right lateral view); no m.a. ( Fig. 25G ). Borders of SES uncertain; gonopods asymmetrical, OG longer; hypandrium with small lobes; phallic guide broad, with an unsclerotised lobe towards SS in ventral view ( Fig. 25J ) and with a membranous part visible in lateral view ( Fig. 25F ); phallus short, trifid; ejaculatory apodeme fan shaped; sperm pump round, with two distal tails ( Fig. 25K ).

Female

As male except for the following characters. Frons, eyes separated; silver-grey pollinose on lower 1/3 and along margins up to 2/3, otherwise shining black. Pulvilli and claws about 1.5 times as long as last tarsal segment on first leg, same length on other legs. Ovipositor broken off.

Distribution— Madagascar.
