Deinodryinus irreptus Olmi, 1994: 6 .

Redescription:

Male.

Macropterous; length 1.9–3.1 mm. Head black, except mandible testaceous; antenna brown; mesosoma black; metasoma brown; legs testaceous, except metacoxa partly brown, club of metafemur and metatibia partly darkened. Antenna filiform, with hairs shorter than breadth of segments; antennal segments in the following proportions: 6:4:5:5:4:4:4:4:4:7. Head shiny, quite strongly punctate, unsculptured among punctae (punctae mostly strong and close on face, similar to areolae); frontal line absent; occipital carina complete; POL= 5; OL= 3; OOL=4; OPL=3; TL =3. Scutum shiny, punctate, unsculptured among punctae (punctae well developed and dense near anterior margin of scutum). Notauli incomplete, reaching approximately 0.6× length of scutum. Scutellum and metanotum shiny, punctate, unsculptured among punctae. Propodeum reticulate rugose, without longitudinal or transverse keels. In specimen from Madagascar, 20°02.42'S 44°39.44'E, propodeum with two tracks of longitudinal keels on posterior surface (area between them rugose). Forewing hyaline, without dark transverse bands; distal part of stigmal vein slightly longer than proximal part (8:7). Paramere ( Figs 12–14 ) about as long as penis, with distal region broadened and with small inner distal branch not wrapping penis. Tibial spurs 1/1/2.

Female. Unknown.

Female.

Macropterous; length 2.7–5.0 mm. Testaceous­reddish; antenna testaceous, except segments 3–10, or 5–10, or 6–10 brown; petiole black; metasoma totally testaceous, or partly brown. In small specimen (2.7 mm) from Madagascar, Ankarana, colour totally testaceous, except petiole black, metanotum brown and last antennae segment darkened. Antenna clavate; antennal segments in the following proportions:12:7:25:10:8:8:8:8:8:11. Head shiny, with face quite strongly punctate and almost reticulate rugose; vertex and temple strongly punctate, not reticulate rugose; frontal line complete or incomplete (then present only on anterior half of face); occipital carina complete; ocellar triangle convex; POL=5; OL=4; OOL =13; OPL=12; TL=8. Pronotum shiny, smooth, strongly punctate, unsculptured among punctae, crossed by transverse impression separating anterior collar from posterior disc; lateral margins of posterior surface of pronotum rounded; pronotal tubercle reaching tegula. Scutum shiny, smooth, strongly punctate, unsculptured among punctae. Notauli incomplete, reaching approximately 0.4–0.5× length of scutum. Scutellum and metanotum shiny, smooth, unsculptured. Anterior margin of metanotum strongly convex and raised into carina. Mesopleuron strongly punctate, with tuft of hairs on anterior third. Metapleuron strongly punctate, not reticulate rugose. Propodeum with dorsal surface reticulate rugose, without transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels, reticulate rugose, except central smooth area. In specimen from Madagascar, 24°39.13'S 43°59.48'E, posterior surface of propodeum with few transverse keels near posterior extremity; in small specimen (2.75mm) from Madagascar, Ankarana, posterior surface of propodeum completely reticulate rugose. Forewing hyaline, with two dark transverse bands; distal part of stigmal vein longer than proximal part (12: 9 in specimen from Madagascar, 24°39.13'S 43°59.48'E). Protarsal segments in following proportions: 11:4:7:16:30. Protarsus without segments produced into hook. Enlarged claw ( Fig. 15 ) with one bristle situated further distally than proximal prominence. Segment 5 of protarsus ( Fig. 15 ) with 2–3 rows of lamellae (about 30–40 small and 7–9 longer); distal apex with about 9–15 lamellae, among which one much longer than others and pointed. Tibial spurs 1/1/2.
