( FIGS 3E–J )

Pipunculus (Eudorylas) hadrosoma Hardy 1962: 262 — comb. nov.

Diagnosis: OS with a broad base in lateral view, SES clear, with distinct hairs, GP asymmetrical, PG broad, with pointed tip and membranous structures bearing scale-like hairs.

Type material: Madagascar: 1♂, HT, Centre Anjavidilava, 2020m, Andringitra Ambalavao , 17–21.I.58, B. Stuckenberg ( MNHN).

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 4 times ocellar triangle. Occiput, upper half brownish, lower half silvery pollinose.

Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) brownish pollinose; more silvery from the side. Scutellum brown, with 8–10 hairs as long as width of t1 at base. Dorsocentral hairs short, but visible. Halter brown. Legs. Trochanters and base of femora yellow-brown, femora brown dorsally on basal half otherwise yellowish brown (posterior surface of f1,2 silvery pollinose, f3 shining dark brown), knees, tibiae yellow, hind tibia clearly bent. Tarsal segments yellow, last segment brown. Ventroapical row of 6–8 short spines on first four femora; 8–10 spines on 3rd femur, somewhat longer. Subapical (distal) spines on first four tibiae present. No anteromedial hairs on 3rd tibia. Hind trochanter with at least 20–25 hairs on ventral side as long as half the width of first tarsus at base. Pulvilli as long as last tarsal segment.

Wing. Fourth costal section as long as third costal section. Cross-vein R-M beyond 2/5 of discal cell. Pterostigma fully coloured. Four-five dark hairs on tegula.

Abdomen. Tergites viewed obliquely from front brownish pollinose (including hind margins), sides slightly greyish. Hairs dispersed and pale, but longer and stronger on sides of T5. Laterally patch of 12–14 black bristles on first tergite. Postabdomen in dorsal view: S7 visible; T5 as long as ST8. Genitalia without dissection: ST8 large, m.a. small (1/3 of width of ST8), EP elongated, SS with finger-like processes.

Genitalia. Surstyli asymmetrical IS longer, with projection, OS with a broad base in lateral view (maybe part of SES). Borders of SES clearly visible with distinct hairs; gonopods asymmetrical, OG longer ( Fig. 3J ); phallic guide broad and in lateral view with pointed tip and membranous parts with scale-like hairs; phallus trifid with membranous supporting structure ( Fig. 3E, J ); ejaculatory apodeme fan-shaped; sperm pump linear ( Fig. 3I ).
