Material examined.

Holotype Costa Rica • ♀; female, Heredia, 3 km S. Puerto Viejo OTS, La Selva; 100 m; x.1992; P. Hanson; huertos Malaise trap set by G. Wright. Paratypes Costa Rica • 1 ♀; same data as for holotype; xi.1992 • 1 ♂; male; same collecting data as for preceding; 10°26'N, 84°01'W; 4. iv. 1987; H. A. Hespenheide.

Diagnosis.

Bohayella geraldinae sp. nov. can be recognized by the following combination of characters: apical maxillary palpomere as long as fifth maxillary palpomere; median crenula of notauli as long as median crenula of scutellar sulcus; scutellar sulcus with one median crenula; hind basitarsus antero-posteriorly slightly expanded; dorsal metasoma mostly pale.

Description.

Female. Body 4.6-4.8 mm. Forewing length: ~ 4.2 mm Antenna length: ~ 4.8 mm. Head. Antenna 34-segmented. Interantennal space with well-developed median carina. POL ~ 1.38 × longer than diameter of anterior ocellus (11:8) (Fig. 3F ). Eye sparsely setose with short setae; median width of eye 0.75 × longer than median width of gena in lateral view (36:48). Width of clypeus ~ 2.07 × longer than height (60:29) (Fig. 3B ). Malar space ~ 2.62 × longer than basal width of mandible (34:13) (Fig. 3B ). Mandible bidentate. Maxillary palpus 6-segmented; apical maxillary palpomere as long as fifth maxillary palpomere. Mesosoma. Mesoscutum with sharp margin (Fig. 3C, F ). Notauli broadly converging at base, with 11 crenulae; median crenula of notauli as long as median crenula of scutellar sulcus (Fig. 3C, F ). Scutellar sulcus with one median crenula (Fig. 3C, F ). Postscutellar depression present (Fig. 3C, F ). Propodeum rugulose with well-defined median areola; median transverse carina on propodeum reaching lateral margin (Fig. 3D, F ). Pronotum dorso-posteriorly crenulate and antero-ventrally smooth. Mesopleuron dorsally and posteriorly with crenulate margin (Fig. 3A ). Mesosternal sulcus broad and crenulate. Metapleuron rugulose. Legs. Basal spur on fore tibia ~ 0.86 × longer than basitarsus (30:35). Width of hind femur ~ 0.34 × longer than its length (42:124). Basal spur on hind tibia ~ 0.76 × longer than basitarsus (58:76). Hind tarsal claw pectinate, with four sharp teeth (Fig. 3E ). Wings. Forewing second submarginal cell trapezoidal, ~ 0.35 × longer than maximum width (30:85); 3r absent (Note: one specimen has basally present 3r vein in particular angle); Rs sharply angled at basal third; stigma ~ 2.67 × longer than medial width (80:30). 1CUa short, 0.23 × longer than 1CUb (12:52). Hind wing 2-1A absent. Metasoma. T1 with a pair of lateral sutures posteriorly reduced, median length of T1 ~ 5.07 × longer than apical width (71:14) (Fig. 3D, F ). T2 with a ball-like projection, medially 0.21 × longer than T1 (15:71) (Fig. 3D, F ). T3 ~ 2.13 × longer than T2 medially (32:15) (Fig. 3D, F ). Protruded ovipositor sheath ~ 0.13 × longer than hind tibia and apically setose (20:154) (Fig. 3A ).

Male. Body ~ 5.0 mm. Same as female except for the following characters: antenna 32-segmented, melanistic color does not reach the dorsal margin of foramen magnum.

Color. Body mostly pale; the following areas are melanistic: antenna, vertex, frons, dorsal occiput, maxillary palpus, labial palpus, lateral mesonotal lobe (pale basally), 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, posterior T5 and T6 (weakly), entire T7 and T8, ovipositor sheath. Wings entirely infuscate, stigma entirely melanistic.

Host.

Unknown.

Distribution.

Bohayella geraldinae sp. nov. is known only from the La Selva Biological Station owned and managed by Organization for Tropical Studies (OTS) in Heredia, Costa Rica at an elevation of 100 m (Figs 1 , 2 ). The station is located in the Caribbean lowlands, at a confluence of the Sarapiquí river and Puerto Viejo ( McDade and Hartshorn 1994). According to Holdridge’s life zone system ( Holdridge 1967), the station is in the tropical wet forest region ( Hartshorn and Peralta 1987), and the average annual precipitation in the area is ~ 4,000 mm ( Sanford et al. 1994).

Etymology.

This species is named in honor of Dr Geraldine Wright, a former student of the second author (SRS), Rhodes Scholar, professor in the Department of Zoology in the University of Oxford (United Kingdom), and the person who set the trap that collected the specimens.
