Type material.

Holotype ♀, Costa Rica: Limon, Bribri, 4 km NE, ix.1989 (Paul Hanson) (ESUW). Paratypes: Costa Rica: 1 ♂, Alajuela, Sta. Clara de San Carlos, 400', 17.ii.1964 (H.E. Evans) (MCZC); 1 ♂, Heredia, Chilamate, 75 m, 25.iii.1989, (Hanson & Godoy) (ESUW); 1 ♀, Heredia, F. La Selva, 3 km S. Pto. Viejo, 10°26'N, 84°01'W, 31.iii.1980 (H.A. Hespenheide) (ESUW); 1 ♀, same locality, ii-iv.1993 (P. Hanson), huertos Malaise trap set by G. Wright (ESUW).

Diagnosis.

Vipio hansoni sp. nov. can be recognised by the combination of the predominantly reddish yellow colour, claw with rounded basal lobe, and the presence of two anterior carinae on raised median area of first metasomal tergite.

Description.

Holotype ♀ length of body 5.5 mm, of fore wing 5.5 mm and of ovipositor 2.9 mm.

Head. Antenna stout, incomplete with 30 flagellomeres remaining; first flagellomere 4.0 × longer than wide; second flagellomere 3.0 × longer than wide; median flagellomeres 1.15-1.2 × longer than wide; first flagellomere 1.5 longer than second; head transverse; face slightly rugulose; clypeus rugulose; clypeal guard setae typical; HL/HH 0.78; HW/HH 0.87; FH/FW 0.69; EH/HH 0.7; EH/FW 1.15; EW/EH 0.8; ITD 1.65 × TOD; MS 0.23 × EH; LMC 0.3 × HH; third segment of maxillary palpus 4.0 × longer than wide.

Mesosoma. Length of mesosoma 1.74 × height; smooth and shiny; notauli smooth; propodeum mostly smooth except slightly rugose posteromedially.

Wings. Fore wing: length of fore wing 1.0 × body length. PL/LRC 0.87; PW/PL 0.18; length of vein 3RSb 0.88 × combined length of r-rs and 3RSa; length of vein 1M 0.61 × length of (RS+M)a; vein 3RSa reaching anterior wing margin 0.67 × distance between apex of pterostigma and wing tip. Hind wings: uniformly setose; apex of vein C+SC+R with one basal hamule.

Legs. Claw with small, rounded basal lobe.

Metasoma. First tergite 1.1 × longer than posteriorly wide, raised median area oval, rugulose, anteriorly with two carinae joining posteriorly and becoming a single median longitudinal carina reaching apex of disc; surrounding area with short transverse carinae; dorso-lateral carina present, area below rugulose; T II 1.7 × wider than long, longitudinally striate, basal areas smooth and shiny, oblique furrow impressed, striate; T III 1.15 × wider than medially long, longitudinally striate, baso-lateral areas smooth and shiny for the most part; T IV longitudinally striate, T V-VII smooth and shiny; hypopygium ending at the apex of metasoma; ovipositor 0.53 × body length.

Colour. Reddish yellow except head, legs, propleuron, and ovipositor sheath black. Wings dark brown.

Variation.

Paratype males (n = 2) as in female, except body length 3.3-3.5 mm; antenna with 32 flagellomeres, gradually shortening and widening distally becoming slightly clavate beyond 25th; a small and short median longitudinal carina present on face below antennae; HL/HH 0.88-0.91; EH/HH 0.74-0.76; EH/FW 1.24-1.27; EW/EH 0.72; ITD 2.8-3.1 × TOD; MS 0.16-0.20 × EH; T II-V densely longitudinally striate; fore wing length equal to body length; face yellow with a median black spot above clypeus, third segment of maxillary palpus, antenna basally, fore and middle legs yellow. Paratype females (N = 2) with terminal flagellomere acutely pointed.

Host.

Unknown.

Distribution and seasonality.

So far recorded only from Limon, Alajuela, and Heredia Provinces in Costa Rica. Specimens were collected in March, April, and September.

Remarks.

This species is closely related to V. godoyi the explanation given under godoyi distinguishes both species. This species also is similar to V. lavignei sp. nov., but the comments given under lavignei separate these species.

Etymology.

Vipio hansoni is named after Professor Paul Hanson, of the Universidad de Costa Rica, who collected the holotype specimen.
