( Figs 34A–G View FIGURE 34 , 40T View FIGURE 40 )

Dorilas (Eudorylas) sinuosus Hardy 1949 a: 56 .

Diagnosis: Large species. Third antennal segment obtuse. Surstyli small compared to postabdomen; epandrium very short; ST8 large, m.a. occupies all of ST8, except upper left angle. SES enlarged, with a wide lobe at the end; phallic guide long, with a groove along median line, tip elongated, pointed (in lateral view with 2 teeth towards SS, the lower with numerous hairs); phallus trifid, extremely long, coiled with supporting structure; ejaculatory apodeme fan shaped; sperm pump with two lateral projections (planes of the two latter parts are turned by 90 degrees). The frons of the female narrows in front of the ocellar triangle, and the pulvilli are as long as the last tarsal segment.

Tarsal segments yellow-brown, last segment brown. Ventroapical row of 8–10 very short, black spines on first four femora; 4–6 weak spines on 3rd femur (all femora with short whitish hairs on front/back sides). Subapical (distal) spines on first four tibiae missing. No anteromedial hairs on 3rd tibia. Hind trochanter with faint whitish hairs on ventral side. Pulvilli as long as last tarsal segment.

Wing. Fourth costal section as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma: distal 4/5 coloured. Hairs on tegula missing.

Abdomen. Viewed obliquely from front tergites subshining black, anterior 1/3 of T2 silver-grey pollinose, sides with greyish pollinose triangles. Hairs relatively dense, whitish. Lateral spines on first tergite: 4–5 dark bristles. Postabdomen in dorsal view: only ST8 visible; T5 0.7–0.8 times as long as ST8. Genitalia without dissection: black, long ST8, large m.a., EP and SS paler.

Genitalia. Surstyli small compared to postabdomen; epandrium very short, especially on the right side; ST8 large, m.a. occupies all of ST8, except upper left angle ( Fig. 34B View FIGURE 34 ). SES enlarged, with a wide lobe at the end; gonopods symmetric, rounded; hypandrium symmetric, narrow, connected to EP; phallic guide long, with a groove along median line ( Fig. 34G View FIGURE 34 ), tip elongated, pointed (in lateral view ( Fig. 34A View FIGURE 34 ) with 2 teeth towards SS, the lower with numerous hairs); phallus trifid, extremely long, coiled (partly drawn), with supporting structure; ejaculatory apodeme fan shaped; sperm pump with two lateral projections (planes of the two latter parts are turned by 90 degrees, Figs 34D, E View FIGURE 34 ).


As male except for the following characters. Frons, eyes separated; silver-grey pollinose except in front of ocellar triangle for length equal to 2 times triangle, also narrowing in front of ocelli. Pulvilli and claws about as long as last tarsal segment (not enlarged). Abdominal tergites greyish pollinose, except distal 1/5 of T2–5, and laterally with grey patches on distal part of tergites.
