Gonadryinus bicarinatus Guglielmino, Olmi, Marletta & Speranza 2017b: 441 .

Description. ♀ ( Figs 154A, B ). Fully winged; body length 3.5–4.4 mm. Head testaceous, except large brown trans- verse band on ocellar region, temple and posterior half of frons; antenna of holotype with first two antennomeres testaceous, other antennomeres missing; antenna of paratype with scape and pedicel testaceous, flagellomeres 1–6 brown (except ADOs whitish), flagellomeres 7–8 whitish; propleuron brown, except ventral side testaceous; pronotum brown, with testaceous spots on posterior collar and pronotal tubercle; mesoscutum brown, except lateral regions partly testaceous; rest of mesosoma black, except mesopleuron partly testaceous; petiole brown; metasoma brown, except ventral side testaceous; legs yellow-testaceous, except club of profemur darkened. In paratype from Madagascar, 21°15.99’S 47°25.21’E, MA-02-09C-60, mesosoma brown-black, except testaceous spots on propleuron, posterior surface of pronotum, lateral regions of mesoscutum, mesopleuron; metasoma brown; legs totally yellow-testaceous. Antenna of holotype with only the first two antennomeres, other antennomeres missing; antennomeres 1-2 in following proportions: 9:6. Antenna of paratype from Madagascar, 21°15.99’S 47°25.21’E, MA- 02-09C-60, very slender, filiform; antennomeres in following proportions: 9:7:45:35:20:14:9:6:6:10. Head slightly swollen, shiny, unsculptured; frontal line of holotype complete (frontal line of paratype incomplete, present only in posterior half of frons); occipital carina complete; holotype with POL = 4; OL = 2; OOL = 6; TL = 5; greatest breadth of lateral ocelli about as long as POL; posterior ocelli touching occipital carina; paratype from Madagascar, 21°15.99’S 47°25.21’E, MA-02-09C-60, with POL = 4; OL = 2; OOL = 6; OPL = 0.5; TL = 5; greatest breadth of lateral ocelli longer than OL (4:2). Palpal formula 5/3. Pronotum shiny, punctate, unsculptured among punctures, crossed by two transverse impressions, anterior one very deep and posterior one weak; anterior collar very long; disc very short and humped; posterior collar short; pronotal tubercle reaching tegula. Mesoscutum ( Fig. 154B ) shiny, with lateral regions unsculptured and median region finely punctate, unsculptured among punctures. Notauli complete, posteriorly separated; minimum distance between notauli shorter than greatest breadth of lateral ocelli (2:4). Mesoscutellum and metanotum almost flat, shiny, unsculptured. Metapectal-propodeal disc dull, with granulate, except two median subparallel keels connecting anterior margin with transverse keel separating metapectal-propodeal disc and propodeal declivity; propodeal declivity with two median longitudinal keels, median area shiny and slightly granulate (in paratype from Madagascar, 21°15.99’S 47°25.21’E, MA-02-09C-60, with some distal transverse keels), lateral areas with two large shiny areolae. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (31:11); 2R1 cell open (almost closed). Protarsomeres of holotype in following proportions: 15:4:6:29:38. Protarsomeres of paratype in following proportions: 16:3:7:30:38. Protarsomere 3 produced into hook. Proleg of holotype with the following proportions: 41 (coxae): 41 (trochanters): 45 (femora): 43 (tibiae): 31 (enlarged claw). Enlarged claw ( Figs 155A, B ) without teeth, with one row of 9–11 lamellae + 1–2 distal lamellae. Holotype with protarsomere 5 ( Fig. 155A ) provided with one row of seven lamellae (with two rows of 2 (proximal) + 7 lamellae in paratype from Madagascar, 21°15.99’S 47°25.21’E, MA-02-09C-60; with two rows of 1 (proximal) + 6 lamellae in paratype from Madagascar, 21°15.05’S 47°24.43‘E) ( Fig. 155B ); apex with group of about 8–10 lamellae. Tibial spurs 1/1/2.
