Dryinus caraibicus Olmi 1984: 849.
Female holotype. Trinidad and Tobago: Trinidad, Arima, Simla (CNC, examined through photographs).
Diagnosis: Body predominantly testaceous except, mesosoma black and one dark band at the vertex; metasoma dark brown; forewing with two dark transverse bands. Body with shorter and dense pilosity, except clypeus and eyes glabrous. Head rugose; pronotum rugose, except for several longitudinal carinae; mesoscutum, mesoscutellum, metanotum, mesopleuron, and metapleuron rugose; propodeum reticulate rugose. Head with vertex flat in frontal view; occipital carina incomplete, present only dorsally; frontal line incomplete near to clypeus; rhinaria composed of two sets in flagellomeres 3–8; notauli complete and divergent in the posterior surface of mesoscutum; stigmal vein of forewing with 2r-rs shorter than 3Rs&4Rs. Enlarged claw with one subapical tooth, and one row of six bristles.
Redescription: Female (Fig. 6). Approximate body length: 4.8 mm. Colour: Head predominantly testaceous, except sulcus in malar space and vertex black (Fig. 6B, C); palpomeres testaceous; mandible testaceous, except by brown teeth; clypeus testaceous; antenna testaceous, except flagellomeres 2–3 brown testaceous (Fig. 6A–C); pronotum testaceous; mesosoma black (Fig. 6A, D, E); legs testaceous, except part of procoxa, mesocoxa, and trochanter; distal part of metafemur and metatibial brown testaceous; forewing with two dark transverse bands; metasoma brown testaceous. Pubescence: Head mostly with fine and dense pilosity (Fig. 6B, C); clypeus glabrous, except by anterior margin with dense pilosity; eye with fine, short, and sparse pilosity (Fig. 6B, C); mesosoma mostly with short and dense pilosity (Fig. 6D, E); mesoscutum with dense and fine pilosity (Fig. 6D); mesoscutellum and central portion of metanotum with dense and short pilosity (Fig. 6D); propodeum with fine and dense pilosity (Fig. 6E); metasoma with short and sparse pilosity. Integumental sculpture: Head rugose (Fig. 6B, C); pronotum rugose, except for several longitudinal carinae (Fig. 6D, E); mesoscutum, mesoscutellum, and metanotum rugose (Fig. 6D); mesopleuron and metapleuron rugose (Fig. 6E); propodeum reticulate rugose (Fig. 6E); posterior surface with two longitudinal, incomplete carinae. Structure and proportions: Occipital carina incomplete, present only dorsally (Fig. 6C). Ocellar ratio: OL = 7; POL = 6; OPL = 4; OOL = 20. Frontal line incomplete, absent near to clypeus. Antennomeres in the following proportions:38: 15: 50: 15: 16: 17: 15: 15: 14: 22. Antenna shorter than head plus mesosoma; 1st flagellomere more 3× than 2nd; 8th flagellomere with two separate sets of rhinaria at the base and a single set apically. Apical margin of clypeus convex. Notauli percurrent and divergent in the posterior surface of mesoscutum (Figs 3E, 6D); metanotum flat (Figs 3E, 6D). Stigmal vein of forewing with 2r-rs shorter than 3Rs&4Rs (30: 43). Enlarged claw with one subapical tooth, and one row of six bristles (Figs 3A, 6F). Protarsomeres in the following proportions: 38: 17: 15: 33: 55, enlarged claw (47). Tibial spur formula 1/1/2. Propodeum with dorsal surface longer than posterior (55: 45).
Male: Unknown.
