description: Eudorylas lobus sp. nov.
(Figs 25A–E)
Diagnosis: Lateral spines on first tergite missing. Surstyli asymmetrical, with hairs along ridges on ventral side, OS with two finger-like projections at tip, IS with a basal round protuberance directed ventrally; epandrium with special tooth shaped form around cerci. SES with distinct hairs; gonopods equal in length; phallic guide broad with two distal round lobes, which are bent behind the central process in lateral view.
Type material: Malawi: 1♂, HT, Viphia, Chikangawa, 27.-ii.-1.iii.1987, J&A Londt, Grassland & forest margins, SE1133DD (NMSA); 1♂, PT, same data as HT (HNHM). South Africa: 1♂, PT, Natal, #46, Midlands, Howick, 29 29’S: 30 13’E, 1060 m, Date: 14.vii.1990, Coll: A.E. Whittington, Garden vegetation (NMSA); 1♂, PT, E. Transvaal, 13km w. Sabie 2530BB, Horseshoe Falls, XII 4, 1976. R. Miller (HNHM).
Male
Head. Third antennal segment acuminate; brown. Face silvery pollinose. Frons, upper part subshining black, lower part silvery pollinose; eyes touching for distance equal to 3 times ocellar triangle. Occiput, lower half silvery pollinose, upper half more brownish.
Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) brownish pollinose, along anterior margin more greyish; also grey from the side. Scutellum brownish pollinose, 4–5 pairs of short, pale hairs. Dorsocentral hairs weakly developed. Halter brownish yellow.
Legs. Trochanters and femora black (hind femur shining posteriorly), knees and tibiae yellow, tibiae with a dark brown ring in the middle (along 1/4 of tibia). Tarsal segments yellow-brown, last segment black. Ventroapical row of 10–12 dark spines on mid femora; no spines on 1st and 3rd femur. Subapical (distal) spines on first four tibiae present. One very weakly developed anteromedial hair on 3rd tibia. Hind trochanter with numerous velvet-like whitish hairs on ventral side. Pulvilli shorter than last tarsal segment.
Wing. Fourth costal section as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.
Abdomen. Viewed obliquely from front tergites 2–4 subshining black, hind margins and sides silvery pollinose; T1 and T5 completely grey. Hairs dispersed, short and weakly developed. Laterally spines on first tergite missing. Postabdomen in dorsal view: S7 visible; T5 2 times as long as T8. Genitalia without dissection: ST8 slightly greyish pollinose, no m.a., EP and SS golden brown.
Genitalia. Surstyli asymmetrical, with hairs along ridges on ventral side, OS with two finger-like projections at tip, IS with a basal round protuberance directed ventrally; epandrium as large as ST8, widest in the middle in dorsal view and with special tooth shaped form around cerci; ST8 relatively small (Fig. 25B). SES with hairs, borders uncertain; gonopods equal in length (Fig. 25E); phallic guide broad with two distal round lobes, which are bent behind the central process in lateral view (Fig. 25A).
Female—Unknown.
Remarks —Closely related to E. amani, but gonopods reach higher and the process of the IS is distinctly larger than in E. amani. The two distal lobes on the phallus are rounded and hairs on the SES are more developed. Both SS with distinct, hairy edges at base in ventral view.
Distribution — Malawi, South Africa.
Etymology —Lobus refers to the two lobe-like lateral extensions of the tip of the phallic guide in ventral view.
