Popis: Gonadryinus bicarinatus sp. nov. (Figures 1, 2) Material examined. Holotype ♀: MADAGASCAR: Fianarantsoa Province, Ranomafana National Park, Belle Vue at Talatakely, 21��15.99'S 47��25.21'E, 1020 m, 26.II���10.III.2003, Malaise trap, secondary tropical forest, R. Harin���Hala leg., MA-02-09C-55 (CAS). Paratypes: MADAGASCAR: same locality label as holotype, 4��� 16.V.2003, MA-02-09C-60, 1♀ (MOLC); Fianarantsoa Province, Ranomafana National Park, radio tower at forest edge, 21��15.05'S 47��24.43'E, 1130 m, 18���27.II.2003, MT, mixed tropical forest, R. Harin���Hala leg., MA-02-09B- 53, 1♀ (CAS); same locality label, 17���30.V.2003, MA-02-09B-61, 1♀ (CAS). Diagnosis. Female with palpal formula 5/3; antenna without tufts of long setae; dorsal surface of metapectalpropodeal complex with two parallel longitudinal keels; enlarged claw without subapical teeth (Fig. 3). Description. Female (Fig. 1). Fully winged; length 3.5���4.4 mm (holotype 3.5 mm). Head testaceous, except large brown transverse band on ocellar region, temple and posterior half of face; antenna of holotype with first two antennomeres testaceous, other segments missing; antenna of paratype MA-02-09B-60 with antennomeres 1���2 testaceous, antennomeres 3���8 brown, 9���10 testaceous-whitish; propleuron brown, except ventral side testaceous; pronotum brown, with testaceous spots on posterior collar and pronotal tubercle; scutum 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 MA- 02-09C-60, mesosoma brown-black, except testaceous spots on propleuron, posterior surface of pronotum, lateral regions of scutum, mesopleuron; metasoma brown; legs totally yellow-testaceous. Antenna of holotype with ratio of antennomeres 1���2 about 9:6. Antenna of paratype MA-02-09C-60, very slender, filiform; ratio of antennomeres about 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 face); occipital carina complete; holotype with POL = 4; OL = 2; OOL = 6; TL = 5; greatest breadth of posterior ocelli about as long as POL; posterior ocelli touching occipital carina; paratype MA-02-09C-60, with POL = 4; OL = 2; OOL = 6; OPL = 0.5; TL = 5; greatest breadth of posterior ocelli about as long as POL. 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. Scutum shiny, with lateral regions unsculptured and median region finely punctate, unsculptured among punctures. Notauli complete (Fig. 2), posteriorly separated; minimum distance between notauli shorter than greatest breadth of posterior ocelli (2:4). Scutellum and metanotum almost flat, shiny, unsculptured. Metapectal-propodeal complex dull, with dorsal surface (probably corresponding to ���metapostnotum��� sensu Kawada et al. 2015) granulated, except two median subparallel carinae connecting anterior margin with transverse keel separating dorsal and posterior surface; posterior surface (probably corresponding to ���first abdominal tergum��� sensu Kawada et al. 2015) with two median longitudinal keels, median area shiny and slightly granulated (in paratype MA-02-09C-60, with some distal transverse keels), lateral areas with two large shiny and slightly granulated areas. Forewing hyaline, without dark transverse bands; distal part of stigmal vein longer than proximal part (31:11); marginal cell open (almost closed). Protarsal segments of holotype in following proportions: 15:4:6:29:38. Protarsal segments of paratype MA-02-09C- 60 in following proportions: 16:3:7:30:38. Protarsal segment 3 produced into hook. Foreleg with following proportions: 41 (coxa): 41 (trochanter): 45 (femur): 43 (tibia): 31 (enlarged claw). Enlarged claw (Fig. 3) without teeth, with one row of 9���11 lamellae + 1���2 distal lamellae. Segment 5 of protarsus (Fig. 3) with one row of 7 lamellae in holotype (with two rows of 2 (proximal) + 7 lamellae in paratype MA-02-09C-60; with two rows of 1 (proximal) + 6 lamellae in paratype MA-02-09B-53); distal apex with group of about 8���10 lamellae. Tibial spurs 1/1/2. Male. Unknown. Hosts. Unknown. Etymology. The specific epithet bicarinatus is a Latin adjective meaning "with two carinae", indicating the two long longitudinal and subparallel carinae present on the dorsal surface of the metapectal-propodeal complex.
