Gonatopus bekilyanus (Benoit) : Olmi 1984: 1612; 1994c: 11; 2004a: 369; 2006: 48; Guglielmino & Olmi 2006: 47; Azevedo et al. 2010: 895; Olmi et al. 2012: 716; 2015: 364.

Description. ♀. Apterous; body length 2.9–3.0 mm. Head black, except clypeus and mandible yellow; antenna brown, except scape and pedicel or only scape yellow; mesosoma and metasoma black; legs yellow, except coxae and clubs of femora brown-black. Head excavated, shiny, bare, unsculptured, except frons and occiput granulate. Palpal formula 3/2 or 4/2. Pronotum crossed by strong transverse impression, shiny, unsculptured. Mesoscutum shiny, with some longitudinal keels, without lateral pointed apophyses. Metanotum transversely striate. Metapectalpropodeal disc shiny, unsculptured; propodeal declivity transversely striate. Meso- and metapleuron transversely striate. Meso-metapleural suture obsolete. In two specimens from Mozambique, Cuamba, metapectal-propodeal disc with deep median longitudinal furrow (furrow not present in other specimens reared in same locality). Enlarged claw ( Fig. 206B ) with small subapical tooth and 5–9 peg-like setae. Protarsomere 5 ( Fig. 206B ) with inner side proximally serrate and one row of 15–24 lamellae; apex with 8–10 lamellae. Tibial spurs 1/0/1.

♂. Fully winged; body length 1.6 mm. Head black, except mandible testaceous; antenna brown; mesosoma black; metasoma brown; legs brown, except articulations and tarsomeres 1–4 testaceous. Antenna setose, filiform; antennomeres of ♂ from Mozambique, Cuamba, in following proportions: 4:3:4.5:4:3.5:4:3.5:4:3:6; antennomere 3 less than 3 × as long as broad: 4.5:2 (in ♂ specimen from Mozambique, Cuamba). Head dull, granulate; fron- tal line absent; occipital carina absent; in ♂ specimen from Mozambique, Cuamba, POL = 5; OL = 3; OOL = 4; greatest breadth of lateral ocelli shorter than OL (2:3). Vertex of head with two oval, dull, granulate areas situated between lateral ocelli and eyes (areas surrounded anteriorly by very high carina; posteriorly not surrounded by carina). Temple distinct, granulate, not crossed by carina. Palpal formula 4/2. Mesoscutum dull, granulate. Notauli complete, posteriorly separated; minimum distance between notauli slightly shorter than greatest breadth of lateral ocelli (1.5:2). Mesoscutellum and metanotum shiny, slightly punctate, unsculptured among punctures. Metapectalpropodeal disc dull, slightly reticulate rugose, without median longitudinal furrow; areolae of metapectal-propodeal disc small; propodeal declivity without longitudinal or transverse keels. Forewing hyaline, without dark transverse bands, with only costal cell surrounded by strongly pigmented veins (other basal cells surrounded by less pigmented veins); 2R1 cell open; 2r-rs&Rs vein regularly curved, with distal part longer than proximal part. Dorsal process of paramere ( Fig. 219A ) short and slender, with apex pointed. Tibial spurs 1/1/2.
