(Figs 8G–L)
Pipunculus (Eudorylas) minymerus Hardy 1962: 264 — comb. nov.
Diagnosis: Eyes touching for distance equal to 5–6 times ocellar triangle. Fourth costal section very short (0.5 times the length of C3). T5 3 times as long as ST8. Surstyli symmetric, slightly curved at tip; with numerous hairs at base of SS; phallic guide pointed and with lobes in ventral view (curved towards SS in lateral view); tubes of the phallus are very thin.

Male
Head. Third antennal segment acuminate; brown. Face silvery pollinose. Frons, upper part shining black, lower part black (and velvet-like) along edges, dull black in the middle; eyes touching for distance equal to 5–6 times ocellar triangle. Occiput silvery pollinose.
Thorax. Humeri black. Mesonotum (viewed obliquely from front) black pollinose, along anterior margin somewhat more shining; brownish pollinose from the side. Scutellum brownish pollinose, with 5–7 longer hairs (as long as width of f1 at base). Dorsocentral hairs weakly developed. Halter brown.
Legs. Trochanters, femora and tibiae brown (f1 and f2 shining posteroventrally), knees and tip of tibiae yellowbrown, hind tibia slightly thickened in the middle. Tarsal segments yellow-brown, last segment brown. Ventroapical row of 6–8 very short spines on first four femora; 10–12 hairs on 3rd femur. Subapical (distal) spines on first four tibiae absent. Two-three erect anteromedial hairs on 3rd tibia. Hind trochanter with 5–6 pale hairs 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 1/3 of discal cell. Pterostigma fully coloured. One hair present on the tegula.
Abdomen. Viewed obliquely from front T2–5 subshining black, hind margins of T2–5 (and T1 completely) brownish pollinose, sides brown on hind margins. Hairs of the abdomen missing, laterally 6–7 dark bristles in a row on first tergite. Postabdomen in dorsal view: T5 3 times as long as ST8. Genitalia without dissection: ST8 very small, m.a. present (half the width of ST8), SS symmetric.
Genitalia. Surstyli symmetric, slightly curved at tip; ST8 with m.a. visible (Fig. 8H). Borders of SES uncertain, with numerous hairs at base of SS; gonopods small, symmetric; hypandrium narrow, elongated; phallic guide pointed and with lobes in ventral view (Fig. 8L) (curved towards SS in lateral view, Fig. 8G); phallus trifid, tubes very thin; ejaculatory apodeme elongated funnel shaped; sperm pump vase shaped (Fig. 8K).
