Lestodryinus schoutedeni Benoit 1950b: 224 .

Dryinus schoutedeni (Benoit): Olmi 1984: 778; 2006: 43; Azevedo et al. 2010: 892.

Description. ♀. Fully winged; body length 6.7–9.4 mm. Head reddish or reddish-dark, except mandible and clypeus testaceous; antenna black, except scape, pedicel and flagellomeres 6–8 testaceous; prothorax reddish or brown-reddish; rest of mesosoma black; metasoma brown; legs brown-black, except tarsi testaceous. In Madagascar there are two different forms: first form almost totally testaceous-reddish, except petiole black, metasoma brown and occasionally mesothoracic axilla blackish; second form almost totally black, except mandible, clypeus, malar space, anterior region of frons near clypeus, lateral regions of pronotum and posterior collar of pronotum testaceous; both forms with antenna testaceous, except antennomere 3 darkened. Antenna clavate; antennomeres of specimen from Zimbabwe, Chishawasha, in following proportions: 8:6:36:20:17:11:9:9:7:7. Head dull, granulate and slightly reticulate rugose; frontal line complete; occipital carina complete; lateral ocelli not touching occipital carina, situated on virtual straight line joining posterior edges of eyes; POL = OL = OPL; TL much longer than OPL. Pronotum (Fig. 140E) dull, granulate, with many keels around disc; pronotum crossed by strong anterior transverse impression and very strong posterior transverse furrow; anterior collar distinct; posterior collar long; pronotal tubercle not reaching tegula. Mesoscutum, mesoscutellum and metanotum dull, granulate, usually with numerous slight longitudinal keels (in specimen from Madagascar, 15°55’S 45°57’E, MG-38-20, mesoscutum very slightly granulate and without longitudinal keels; in specimen from Madagascar, 16°08’S 45°42’E, mesoscutum completely unsculptured). Notauli incomplete, approximately reaching 0.65 × length of mesoscutum. Metapectal-propodeal disc reticulate rugose, about 3 × as long as propodeal declivity; propodeal declivity reticulate rugose, with two longitudinal keels. Forewing with two dark transverse bands; distal part of 2r-rs&Rs vein about twice as long as proximal part. Protarsomere 1 about as long as 4; protarsomere 3 produced into hook. Enlarged claw (Fig. 140F) with one large subdistal tooth and one row of 18 lamellae. Protarsomere 5 (Fig. 140F) with two rows of about 34 lamellae; apex with about 13 lamellae. Tibial spurs 1/1/2.

Remarks. The ♀ population from Madagascar is apparently characterized by a colour different from that of other African populations. The specimens from continental Africa, have the body partly testaceous-reddish (head and prothorax) and partly black, whereas the Madagascar population has the body totally testaceous-reddish or totally black. Only one totally black specimen is known (from Manakambahiny), whereas five testaceous-reddish specimens are known from Tsimbazaza Park, Alaotra Lake, 25 km W of Morarano-Chrome and Alaotra Station, and from 15°55’S 45°57’E. The small number of known specimens means that we need to postpone assessment of this population. These specimens from Madagascar have a morphology similar to that of the continental population; the only differences are in the colour. Possibly they are a different species. It is prudent to wait for further specimens, before reaching a decision on the status of this population. The testaceous-reddish specimens from Madagascar are 8.1 mm long, whereas the black specimen is 6.7 mm long. The main characters may be summarized as follows: antennomeres in following proportions: 12:6:53:30:23:16:12:10.5:8.5:10; POL = 2.5; OL = 2; OOL = 12; OPL = 2; TL = 6; distal part of 2r-rs&Rs vein longer than proximal part (19:10); Protarsomeres in following proportions: 31:4:9:27:41; enlarged claw with one large subapical tooth and one row of 15 lamellae; protarsomere 5 with two rows of approximately 41 lamellae; apex with at least 20 lamellae.
