FÖLDVÁRI, MIHÁLY, 2013, Taxonomic revision of the Afrotropical species of the tribe Eudorylini (Diptera, Pipunculidae), Zootaxa 3656 (1), pp. 1-121 : 34-35

Eudorylas abdominalis ( Loew, 1858)

( Fig. 39M )

Pipunculus abdominalis Loew 1858: 374 [ 1860: 354].

Diagnosis: All tergites in lateral view and T5 entirely are yellow. But only the female HT is known so far therefore identifications must be made with caution.

Type material: South Africa: 1♀, HT, Caffraria [2 hand-written labels:] “235.”, “167”, [typewritten label:] “ Pipunculus abdominalis ” ( NHRS).

Other material examined: South Africa: 1♀, Natal Umgeni Calley Ranch , 1km N Howick 2930 Ac, 7-IV-1980, R. Miller & P. Stabbins; ( NMSA) .

Female

Head. Third antennal segment acuminate; yellow. Face silvery pollinose. Frons, upper part shining black, Vshaped turns (in the middle of the frons) continuously into the silvery pollinose (lower) part. Occiput, lower half silvery pollinose, upper half brownish.

Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) silvery pollinose; also grey from the side. Scutellum grey, with 3–4 pairs of pale hairs. Dorsocentral hairs very weakly developed. Halter yellow.

Legs. Completely yellow. Ventroapical row of 4–5 very short, dark spines on f2; no spines on f1,3. Subapical (distal) spines on first four tibiae well developed. One or two erect, pale anteromedial hairs on 3rd tibia. Hind trochanter covered with minute brown hairs on ventral side. Pulvilli slightly longer than last tarsal segment.

Wing. Fourth costal section as long as third costal section. Cross-vein R-M at 2/5 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.

Abdomen. Viewed obliquely from front tergites (shining): T1 yellow-brown completely, T2–4 brown in the middle (ca. 1/3), yellow on both sides dorsally, T5 almost entirely brown. In lateral view all tergites are yellow. Hairs dispersed, pale and weakly developed. Laterally 2 dark spines on first tergite.

Ovipositor ( Fig. 39M ). Base dark brown, piercer yellow-brown, about as long as base.

Male—no males with certain association.

Remarks —The type specimen was collected during a Swedish expedition to southern and south-eastern Africa led by J.A. Wahlberg. The numbers refer to particular localities, but the list of localities had disappeared and correct labels had never been produced according to Thomas Pape, NHRS (pers. comm.). The specimen is from “Caffraria”, which refers to a large part of current South Africa. Loew 1858 (p. 374) gives the type locality as “Caffraria (Wahlb.)”, but does not mention the number of specimens he had studied.

Distributional data other than listed in material examined are based on De Meyer 1996.

Distribution— Burundi, Democratic Republic of Congo, Madagascar, Rwanda, South Africa, Tanzania, Uganda, Zimbabwe.
