Taxon classification Animalia Hymenoptera Dryinidae
Head completely sculptured by longitudinal subparallel keels, on face (Fig. 3), vertex and temple; paramere (Fig. 4) with distal part of inner margin provisioned with many sensorial processes.
Male. Fully winged (Fig. 1). Body length 2.8 mm. Head black, except mandible testaceous; antenna brown; mesosoma and metasoma black; legs brown, except most part of coxae black. Antenna filiform; antennal segments in following proportions: 11:5:13:14:13:12:10:9:8:10. Head shiny, completely sculptured by longitudinal subparallel keels, on face (Fig. 3), vertex and temple; frontal line complete; occipital carina complete; POL = 5; OL = 3; OOL = 7; OPL = 7; TL = 10; greatest breadth of lateral ocelli about as long as OL. Scutum (Fig. 2) shiny, with anterior half slightly rugose; posterior half, punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 × length of scutum. Scutellum punctate, unsculptured among punctures. Metanotum dull, rugose. Propodeum reticulate rugose, without transverse or longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein about as long as proximal part (Fig. 1), about as long as antennal segment 3. Paramere (Fig. 4) with distal part of inner margin provided of many sensorial processes. Tibial spurs 1/1/2.
Holotype: male, MADAGASCAR: Fianarantsoa Province, Andringitra National Park, Plateau d’Andohariana, 35.9 km 205° Ambalavao, 22°09.08'S 46°53.57'E, 2000 m, 15.IV.2006, Malaise trap, BL Fisher et al. leg., BLF13755 ( CAS).
The two main characters distinguishing the new species are detailed in the above diagnosis. These characters are not present in any of the known species of Conganteoninae ( Olmi and Xu 2015; Xu et al. 2013).
The species is named sulcatum because the head is sculptured by many longitudinal subparallel keels.
