Eudorylas denotatus (Hardy, 1959) View in CoL

( Figs 17H–M View FIGURE 17 )

Dorilas (Eudorylas) denotatus Hardy 1959 a: 400 View in CoL .

Diagnosis: One erect anteromedial hair on 3rd tibia. Surstyli broad at base in dorsal view, both with distinct basal projections in lateral view. Hypandrial apodeme well developed; phallic guide with two large lobes at tip in ventral view (almost as long as SS), PG distinctly bifurcated in lateral view; ejaculatory apodeme linear; sperm pump with two lateral lobes.

Type material: South Africa: 1♂, HT, S. Afr, Cape Prov., Cape Peninsula, Hout Bay Skoorsteenkop , 22.I.51, No. 157; Swedish South Africa Expedition 1950–1951, Brinck-Rudebeck; Insect trap ; 1♀, AT, same data, 2.II.51, No 166 ; 1♂, 1♀, PTs, same data as HT; Type No : 2124: 1–4 (all ZML); 1♀, PT, same data as HT ( USNM) .

Other material examined: South Africa: 1♂, Cape Prov, 4.5 mi [les] S. [of] El andsbaai, Sept.17, 1972, M. E. Irwin, Coastal sand plain, 50 ft. alt., 3218 Ad ; 1♂, Cape Prov., 5km N of Nieuwoudtville , 16.xi.1986, 3119AC, Londt & Quickelberge, 760m, Stream Macchia (both NMSA) .

Male

Head. Third antennal segment acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose except black upper corner; eyes touching for distance equal to 2.5–3.5 times ocellar triangle. Occiput greyish pollinose.

Thorax. Humeri yellow-brown. Mesonotum (viewed obliquely from front) brownish pollinose; slightly greyish from the side. Scutellum brownish pollinose, with 7–8 pairs of pale hairs. Dorsocentral hairs weakly developed. Halter: knob dark brow, stem pale.

Legs. Trochanters and base of femora yellow, femora brown, f3 shining posteriorly, knees, tibiae and tarsal segments yellow, last segment brown. Ventroapical row of 4 spines on f1, 12–14 very short, black spines on f2; no spines on 3rd femur. Subapical (distal) spines on first four tibiae present. One erect anteromedial hair on 3rd tibia. Hind trochanter with 3–4 white hairs on shiny ventral side. Pulvilli as long as last tarsal segment.

Wing. Cross-vein R-M beyond 2/5 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.

Abdomen. Viewed obliquely from front tergites brownish pollinose, hind margins somewhat greyish, sides completely grey. Hairs dispersed, short and weakly developed, mainly on ST8. 4–5 black, lateral bristles on first tergite. Postabdomen in dorsal view: S7 visible; T5 0.8 times as long as ST8. Genitalia without dissection: postabdomen yellowish brown, ST8 enlarged, m.a. elliptic, SS visible, large.

Genitalia. Surstyli broad at base, otherwise long and narrow in dorsal view, both with distinct basal projections in lateral view; ST8 large ( Fig. 17I View FIGURE 17 ). SES uncertain; gonopods may be missing; HA well developed; phallic guide with two large lobes at tip in ventral view (almost as long as SS) ( Fig. 17L View FIGURE 17 ), PG distinctly bifurcated in lateral view ( Fig. 17H View FIGURE 17 ); phallus trifid with phallic sheath at base attached to HA; ejaculatory apodeme linear; sperm pump with two lateral lobes ( Fig. 17M View FIGURE 17 ).

Female

As male except for the following characters. Frons, eyes separated; silver-grey pollinose on 1/3 close to the antennae and along lateral margins until 2/3, otherwise shining black. Pulvilli and claws about 1.8–2 times as long as last tarsal segment. Female ovipositor stout, base surrounded by enlarged T6, which hides it in lateral view; piercer much longer than base (cf. E. amuscarium ).

Remarks —This species is related to E. amuscarium based on external morphology (3rd antennal segment, ventroapical spines on femora, hair on t3) and shape of genitalia (distally narrowing SS, with hairs at base ventrally, shape of PG, sperm pump and ejaculatory apodeme). They still differ in the size of m.a.; shape of EP, SS and there is no extra structure connected to PG.

Distribution— South Africa.
