description: Triraphis areatus (Enderlein), comb. n.
Rhogas areatus Enderlein, 1918. Rogas areatus Dalla Torre, 1898.
Description. Female. Body color: yellow, with antenna yellow and distal edge of flagellomeres darker; telotarsus brownish yellow as tarsal claws. Fore wing: C+SC+R, M+CU distal 1/3, 11 – A, 1M (except anterior tip) and RS+Ma (except distal tip) brownish yellow, remainder yellow; hind wing: veins yellow. Wings hyaline. Body length = 5.42 mm; fore wing length = 4.80 mm.
Head: Width of oral opening/height of oral opening = 2.0. Antenna, flagellomere all longer than wide, base of toruli with few rugose sculpturing present; malar space slightly wider than basal width of mandible; occipital carina effaced dorsally, not fused with hypostomal carina, clearly separated; median ocellus as big as lateral ocellus; space between lateral ocellus black; ocell-ocular distance almost as lateral ocellus width.
Mesosoma: Length of mesosoma in dorsal view/width of mesosoma = 2.66; height of mesosoma = 1.14 mm; propleuron dorso-lateral area with defined colliculate sculpturing present basally; notauli punctate, defined medially; medial longitudinal pit present, nitid without longitudinal punctate sculpturing; mesonotum distal 1/4 with less defined colliculate sculpturing present medially, remainder nitid; sternauli with spaced striate sculpturing as union with prepectal carina, area below with confused colliculate sculpturing; mesopleuron dorso-lateral area with finely colliculate and little rugose sculpturing; mesepimeron ventral area with less defined colliculate sculpturing; metapleuron granulate, ventral area without rugose sculpturing; propodeum, spiracles sub – oval; first lateral areas of propodeum without areolate – rugulose, fine granulate sculpturing present, remainder with spaced areolate-rugulose and less defined colliculate sculpturing; medial carina 1/4 propodeum length; areola with irregular sub-triangular shape; ventral tubercles present without carinae and densely granulate.
Legs: basal lobe at hind tarsal claw broad, short and rounded at tip.
Wings: fore wing: 3RSa/lRS = 4.30; r = 0.24 mm. hind wing: lM/r – m = 1.90; m+cu before 2RS; 2RS straight; angle at union 2RS – 2M acute; pterostigma yellow.
Metasoma: Length of first metasomal tergum/width of first metasomal tergum = 1.14; length of second metasomal tergum/width of second metasomal tergum = 0.71; length of third metasomal tergum/width of third metasomal tergum = 0.40; anterior width of first tergum = 0.39 mm; hypopygium =?; Anterior–triangular area of first metasomal tergum open with carinae present, medial carina normal; first metasomal tergum lineate sculpturing as second metasomal tergum sculpturing; third metasomal tergum lineate sculpturing finer, closer and less conspicuous than second metasomal tergum sculpturing, not reaching distal 1/3; fourth metasomal tergum without fine lineate sculpturing
Type specimen examined. HNHM, female type collected at Belize (British Honduras), Matanae.
Material collected in Costa Rica. One female; San José, Ciudad Colón, 800 m. xii/1989 – i/1990, Col. L. Fournier.
Distribution. The altitudinal range of this species is mid-elevations (800 m).
Comments. Type specimen with antennae broken; measurement of hypopygium length was impossible because of the way that the specimen was mounted. The Costa Rican specimen was collected at tropical premontane wet/rain forest.
The type specimen was assessed as a new combination within the genus Triraphis according to the label placed by van Achterberg in 1997; with the present publication we formally recognized and officialize the new combination proposed by him.
