FÖLDVÁRI, MIHÁLY, 2013, Taxonomic revision of the Afrotropical species of the tribe Eudorylini (Diptera, Pipunculidae), Zootaxa 3656 (1), pp. 1-121 : 41-43

Eudorylas amitinus ( Hardy, 1962)

( Figs 13H–M )

Pipunculus (Eudorylas) amitinus Hardy 1962: 253 .

Pipunculus (Eudorylas) fractus Hardy 1962: 260 — syn. nov.

Diagnosis: Eyes touching for distance equal to 4–5 times ocellar triangle. Three to four anteromedial hairs on 3rd tibia. Surstyli similar in shape but inner tips different; SES clearly visible, with thick hairs medially; phallic guide with parallel sides in ventral view, slightly pointed in lateral view.

Type material: Madagascar: 1♂, HT, Madagascar, Centre, Anjavidilava 2020m, Andringitra Ambalavao, 17– 21.I.58 B. Stuckenberg ( MNHN) ; 1♂ [HT of E. fractus ], [Central] Madagascar Tan., Ambohitantely, 11.VI.58, F. Keiser ( NHBM) .

Male

Head. Third antennal segment acuminate; brown or yellow. Face silvery pollinose. Frons, upper part shining black, lower part pollinose along margins, subshining black in the middle; eyes touching for distance equal to 4–5 times ocellar triangle. Occiput, lower half silvery pollinose, upper half more brownish.

Thorax. Humeri brown to dark brown. Mesonotum (viewed obliquely from front) brownish pollinose; more silvery from the side. Scutellum brown, 8–10 short, pale hairs. Dorsocentral hairs well developed, pale. Halter brown to dark brown.

Legs. Entirely yellow brown or brown (f3 shining pv). Ventroapical row of spines on four femora missing. Subapical (distal) spines on first four tibiae missing. Three to four anteromedial hairs on 3rd tibia. Hind trochanter with 5–6 short, pale hairs on ventral side. Pulvilli half as long as last tarsal segment.

Wing. Fourth costal section 0.8–1.1 times as long as third costal section. Cross-vein R-M beyond 2/5 of discal cell. Pterostigma fully coloured. Two dark hairs present on tegula.

Abdomen (already dissected). Viewed obliquely from front tergites brownish pollinose. Hairs dispersed, short and weakly developed. Laterally 3–4 dark spines on first tergite.

Genitalia. Surstyli similar in shape but inner tips different; epandrium short and broad; ST8 broadened, m.a. circular ( Fig. 13I ). SES clearly visible, connected to SS, with thick hairs medially; gonopods short, symmetrical; phallic guide with parallel sides in ventral view ( Fig. 13M ), slightly pointed in lateral view ( Fig. 13H ); phallus linear; sperm pump elongated, with two small projections, border with sperm trifid, short; ejaculatory apodeme duct uncertain ( Fig. 13K ).

Female—Unknown.

Remarks —Synonymy is proposed, because of similarity of genitalia: SS with two apical projections and PH, PG identical in shape. Legs are darker on the type of E. amitinus and paler on the type of E. fractus , but they are neither black (for E. amitinus ) nor yellow (for E. fractus ) as in Hardy 1962 (pp. 54, 61).

Distribution— Madagascar.
