Eudorylas facetus (Hardy, 1962)

(Figs 20A–F, 39I)

Pipunculus (Eudorylas) facetus Hardy 1962: 259 .

Diagnosis: Fourth costal section short (half the length of third costal section). Cross-vein R-M at 1/4–1/3 of discal cell. Epandrium with uncertain borders around cerci in dorsal view; phallic guide broad at base, narrow at tip in ventral view; narrow and sharply pointed in lateral view. Phallus trifid with supporting structure and setulose membranous lobe. Females with short pulvilli.

Type material: Madagascar: 1♂, HT, [Central] Madagascar Tan., Ambohitantely, 10.VI.58, F. Keiser ; 1♀, AT, ibid., 11.VI.58 (both NHMB); 1♂, PT, same data as AT (BPBM) .

Male

Head. Third antennal segment acuminate; yellow. Face silvery pollinose. Frons (covered with glue on HT), eyes touching for distance equal to 3 times ocellar triangle. Occiput silvery pollinose.

Thorax. Humeri dark brown. Mesonotum (viewed obliquely from front) brown; more pollinose from the side. Scutellum brown, with 3–4 pairs of weakly developed hairs. Dorsocentral hairs covered by glue on HT. Halter yellow-brown.

Legs. Entirely yellow (incl. last tarsus). Ventroapical row of spines missing on first four femora; 8–9 very short, black spines on 3rd femur. Subapical (distal) spines on first four tibiae missing. 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 0.5 times as long as third costal section. Cross-vein R-M at 1/4–1/3 of discal cell. Pterostigma coloured on distal 4/5. Hairs on tegula missing.

Abdomen. Elongated, viewed obliquely from front tergites completely shining black, ST8 slightly pollinose. Abdominal hairs missing. Laterally 2–3 weakly developed hairs on first tergite. Postabdomen in dorsal view: T5 1.4 times as long as ST8. Genitalia without dissection: SS yellow, m.a. present, borders uncertain.

Genitalia. Surstyli subsymmetrical; epandrium with uncertain borders around cerci in dorsal view; ST8 with m.a. (as large as half the width of ST8, Fig. 20B). SES uncertain; gonopods symmetrical, rounded; phallic guide broad at base, narrow at tip in ventral view (Fig. 20F); narrow and sharply pointed in lateral view (Fig. 20A). Phallus trifid with supporting structure and setulose membranous lobe; ejaculatory apodeme mushroom-shaped, long; sperm pump round (Fig. 20E).

Female

As male except for the following characters. Frons, eyes separated; silver-grey pollinose on lower 1/3, otherwise shining black, greyish along lateral margins. Pulvilli and claws shorter than last tarsal segment. Female ovipositor as in Fig. 39I.

Remarks —Females have short pulvilli, which is quite rare in Pipunculidae .

Distribution— Madagascar.
