Material examined.

Holotype Costa Rica • ♀; female, Puntarenas, San Vito, Estac. Biol., Las Alturas; 1,500 m; vi.1992; Paul Hanson; traps #1 + #2, Malaise. Paratypes Costa Rica • 2 ♀; same data as for holotype • 2 ♀; same collecting data as for preceding • 1 ♀; female; same collecting data as for preceding; 1,700 m; 11.iv.1993.

Diagnosis.

Bohayella hansoni sp. nov. can be distinguished from B. geraldinae sp. nov. by the following characters: apical maxillary palpomere slightly longer than fifth maxillary palpomere; median crenula of notauli ~ 0.38 × longer than median crenula of scutellar sulcus; scutellar sulcus with three crenulae; hind basitarsus cylindrical; dorsal metasoma mostly melanistic.

Description.

Female. Body 3.9-4.1 mm. Forewing length: 3.9-4.1 mm Antenna length: 4.1-4.5 mm. Head. Antenna 32-34-segmented. Interantennal space with well-developed median carina. POL 1.22 × longer than diameter of anterior ocellus (11:9) (Fig. 4B ). Eye sparsely setose with short eye setae; length of eye ~ 0.86 × longer than median width of gena in lateral view (31:36). Width of clypeus 2.00 × longer than height (56:28) (Fig. 4C ). Malar space 1.80 × longer than basal width of mandible (36:20) (Fig. 4C ). Mandible bidentate. Maxillary palpus 6-segmented; apical maxillary palpomere 1.31 × longer than fifth maxillary palpomere (17:13). Mesosoma. Mesoscutum with sharp margin (Fig. 4B, D ). Notauli broadly converging at base, with 11 crenulae; median crenula of notauli ~ 0.38 × longer than median crenula of scutellar sulcus (6:16) (Fig. 4B, D ). Scutellar sulcus with three crenulae (Fig. 4B, D ). Postscutellar depression present (Fig. 4B, D ). Propodeum rugulose, with well-defined median areola; median transverse carina on the propodeum reaching lateral margin (Fig. 4B, E ). Pronotum dorso-posteriorly crenulate and antero-ventrally smooth. Mesopleuron dorsally and posteriorly with crenulate margin (Fig. 4A ). Mesosternal sulcus broad and crenulate. Metapleuron rugulose. Legs. Basal spur on fore tibia ~ 0.87 × longer than basitarsus (26:30). Width of hind femur ~ 0.30 × longer than its length (33:111). Basal spur on hind tibia ~ 0.81 × longer than basitarsus (58:72). Hind tarsal claw pectinate with four acute teeth. Wings. Forewing second submarginal cell trapezoidal, ~ 0.34 × longer than its maximum width (26:77); 3r absent; Rs sharply angled at basal third; stigma ~ 2.82 × longer than medial width (79:28). 1CUa short, 0.23 × longer than 1Cub (11:47) (Fig. 4A ). Hind wing 2-1A absent. Metasoma. T1 with a pair of lateral sutures posteriorly reduced, median length of T1 4.00 × longer than apical width (56:14) (Fig. 4B, E ). T2 with a ball-like projection, medially ~ 0.20 × longer than T1 (11:56) (Fig. 4B, E ). T3 ~ 2.55 × longer than T2 medially (28:11) (Fig. 4B ). Protruded ovipositor sheath ~ 0.20 × longer than hind tibia and apically setose (26:129) (Fig. 4A ).

Color. Body mostly pale; the following areas melanistic: antenna, vertex, frons, dorsal occiput, maxillary palpus, labial palpus, lateral mesonotal lobe (basally pale), lateral scutellum, margin of metanotum, apical fore femur, fore tibia, apical fore tarsus, apical mid femur, mid tibia, apical mid tarsus, apical hind femur, basal and apical hind tibia, apical hind tarsus, T2-T8, ovipositor sheath. Wings entirely infuscate, stigma entirely melanistic.

Male. Unknown.

Host.

Unknown.

Distribution.

Bohayella hansoni sp. nov. is known only from the Las Alturas Biological research station owned and operated by Stanford University in Las Alturas, San Vito, Costa Rica at the elevations of 1,500 m and 1,700 m (Figs 1 , 5 ).

Etymology.

This species is named in honor of Dr Paul Hanson, collaborator and professor at the Escuela de Biología, Universidad de Costa Rica. He worked tirelessly for many years collecting and sorting Costa Rican braconids from Malaise samples. SRS is very grateful for his dedication to Hymenoptera studies.
