Head yellow-testaceous; antenna brown, except scape and flag- ellomere 8 white or yellow; occasionally flagellomere 8 brown; mesosoma yellow-testaceous; petiole black; metasoma brownish or yellow-testaceous; legs yellow-testaceous. Head ( Fig. 174L View FIGURE 174 ) excavated. Palpal formula 3/2 or 4/2. Pronotum crossed by strong transverse impression. Mesoscutum without lateral pointed apophyses ( Fig. 174J View FIGURE 174 ). Metanotum transversely striate, about coplanar to mesoscutellum ( Fig. 174K View FIGURE 174 ), with sides protruding ( Fig. 174J View FIGURE 174 ); in holotype lateral protrusions of metanotum rounded ( Fig. 174J View FIGURE 174 ); in specimen from South Africa, 26°45.58’S 27°48.22’E, lateral protrusions of metanotum pointed. Metapectal-propodeal disc shiny, unsculptured. Mesopleuron, metapleuron and propodeal declivity transversely striate. Meso-metapleural suture distinct and complete. Protarsomere 1 slightly longer than 4 (12:11). Enlarged claw ( Fig. 176D View FIGURE 176 ) with one large subapical tooth and one row of 8–11 lamellae. Protarsomere 5 ( Fig. 176D View FIGURE 176 ) with two rows of 16–19 lamellae; apex with 9–13 lamellae. Tibial spurs 1/0/1.
♂. Fully winged; body length 1.1 mm. Head brown; antenna testaceous; mesosoma and metasoma brown; legs testaceous and partly darkened. Antenna filiform; antennomeres in following proportions: 3.5:3:4:3:3:3.5:3.5:3:4:6; third antennomere 4 × as long as broad (4:1). Head shiny, granulate, with two smooth areas on sides of lateral ocelli; frontal line absent; occipital carina absent; POL = 5; OL = 2; OOL = 3. Palpal formula 4/2. Mesoscutum shiny, granulate. Notauli complete, posteriorly joint. Mesoscutellum and metanotum shiny, finely punctate, unsculptured among punctures. Metapectal-propodeal disc shiny, dorsally unsculptured, laterally rugose. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (10:5). Dorsal process of paramere ( Fig. 173E View FIGURE 173 ) long and slender.

Hosts. Delphacidae ( Guglielmino et al. 2013) : in La Reunion: Peregrinus maidis Ashmead ; in Mauritius: Perkinsiella saccharicida Kirkaldy and Numata muiri (Kirkaldy) (= Dicranotropis muiri Kirkaldy ); in Mozambique: unidentified Delphacidae ; in South Africa: Sogatella kolophon (Kirkaldy) .
Biology. The biology of this species was partly studied in Mauritius by Williams (1956). The pupal stage in Mauritius lasts 18–24 days in March-April.
Natural enemies. In Mauritius this species may be parasitized by Cheiloneurus gonatopodis R. Perkins 1906 (Encyrtidae) ( Williams 1956, 1958; Prinsloo 1983; Ganeshan & Williams 2000; Guerrieri & Viggiani 2005).
Distribution. Gambia, Kenya, La Reunion, Lesotho, Mauritius, Mozambique, South Africa.
Remarks. Gonatopus similis Brues and Pseudogonatopoides mauritianus Williams were considered synonyms by Olmi (1984) after comparison of ♀♀. However, only the study of ♂ specimens from Mauritius can confirm this synonymy.
