Eudorylas remiformis ( Hardy, 1962)

( Figs 30F–K , 39E )

Pipunculus (Eudorylas) remiformis Hardy 1962: 266 .

Diagnosis: Third antennal segment long acuminate. S7 and EP visible in dorsal view of the abdomen. Surstyli subsymmetrical, club shaped and strongly bent ventrally; ST8 very small, without m.a.; gonopods subsymmetrical with distinct hairs around tip; phallic guide blunt at tip in ventral view (with minor hairs on the side on distal 2/3), but curved and pointed in lateral view.

Type material: Madagascar: 1♂, HT, [Central] Madagascar Tan., Manjakatompo , 23.IV.58 F. Keiser ; 1♀, AT, ibid., Tananarive, 14.VII.58 ; 1♀, PT, same data as AT ; 1♀, PT, same as HT, [East Madagascar] Maroantsetra , 18.XI.57 ; 1♀, PT [no head, not E. remiformis ], ibid., Ambohitantely, 11.VI.58 [as “8. VI. 58” in Hardy 1962] (all NHMB) .

Male

Head (deformed in HT). Third antennal segment brown; long acuminate. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose; eyes touching for distance equal to 3 times ocellar triangle. Occiput silvery pollinose.

Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) brownish pollinose; more silvery from the side. Scutellum brown, with 6–7 pairs of pale hairs. Dorsocentral hairs weakly developed, notopleural depression with pale hairs as long as width of t3 at base. Halter brown.

Legs. Trochanters and base of femora and femora dark brown (f1,2 silvery pollinose, f3 shining black on pv surface), knees yellow-brown, tibiae dark brown except yellowish tip, hind tibia (shape). Tarsal segments yellow, last segment brown. Ventroapical row of spines missing on f1 and f3; 4–6 short, dark spines on f2. 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 1.7 times as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma coloured on distal 3/4. Hairs on tegula missing.

Abdomen. Tergites viewed obliquely from front and hind margins subshining black, sides greyish pollinose. Hairs dispersed, short and weakly developed. Laterally outstanding spines missing on first tergite. Postabdomen in dorsal view: S7 and EP visible; T5 1.25 times as long as ST8.

Genitalia. Surstyli subsymmetrical, club shaped and strongly bent ventrally; epandrium short and broad; ST8 very small, without m.a. ( Fig. 30G ). Borders of SES uncertain; gonopods subsymmetrical with distinct hairs around tip; hypandrium short, internal structure uncertain; phallic guide blunt at tip in ventral view (with minor hairs on the side on distal 2/3, ( Fig. 30K )), but curved and pointed in lateral view ( Fig. 30F ); phallus uncertain (may be lost); ejaculatory apodeme linear; sperm pump small, border with sperm duct blurred/inconspicuous ( Fig. 30I ).

Female

As male except for the following characters. Frons, eyes separated; silver-grey pollinose on lower ¼, golden-brown up to the middle and the upper half shining black (especially along the median line), along lateral margins slightly pollinose. Pulvilli and claws about 1.5 times as long as last tarsal segment. First abdominal tergite with 2–3 dark brown hairs. Pterostigma of the wing fully coloured. Female ovipositor as in Fig. 39E .

Remarks —The PT female from Ambohitantely (without head) belongs to another species based on the shape of the ovipositor (base larger, piercer shorter), longer claws and pulvilli and different wing venation (R-M almost in the middle of discal cell). A more exact species identity cannot be given as in other cases when only females are available.

Distribution— Madagascar.
