Figs 112-115 Diagnosis . Presence of 2 tubercles on the apex of the carapace. The penultimate flagellomere is almost the same length as the ultimate flagellomere. The carapace is completely brownish black; head and carapace brownish black; mesosoma mostly orange, anteriorly and ventrally blackish; wings lightly pigmented with yellowish brown venation.

Leptodrepana stasia . 112 Female habitus in lateral view 113 metasoma in lateral view 114 metasoma in dorso-posterior view with a couple of pointing-terminal projections 115 head and mesoscutum in dorsal view. Holotype female. BL 2.53 mm; FWL 2.13 mm; CL 1.16 mm; CW 0.36 mm; CL/CW 3.2. Description. Color. Head brownish black, mandibles yellow, blackish brown apically; palpi yellowish white; antennae brown with scape, pedicel and first flagellomere yellowish white; mesosoma mostly orange, median mesonotal lobe black, postero-ventral portion of mesopleuron black, posterior metapleuron black; propodeum orangish black; middle and fore leg coxae yellowish white, remainder of legs brown; hind leg coxa brown basally and yellowish brown apically, trochanter yellowish brown, femur and tibia brown and tibia with basal white band; wings lightly pigmented with yellowish brown venation; carapace blackish brown. Head. HW 0.73 mm; HL 0.6 mm; HW/HL 1.22; face, genae, vertex and ocellar triangle rugulose-punctate; frons depressed, rugulose-punctate and median carina present; clypeus punctate and apical margin rounded; occipital carina complete. Mesosoma. Pronotum foveate antero-laterally to rugose-punctate at propleural margin; propleuron weakly areolate-rugose; mesoscutum medially with irregular parallel pitted grooves between notauli difficult to distinguish and appears areolate-rugose; notauli visible anteriorly; median and lateral mesonotal lobes rugose-punctate; scutellar sulcus with 6 well-defined depressions, all longer than wide; scutellar disc punctate; mesopleuron anteriorly rugose foveolate, medially weakly punctate, narrow foveate band at precoxal sulcus, foveolate postero-ventrally; propodeum coarsely areolate-rugose with distinct transverse carina raised into small and roughly equal medial and lateral flanges. Metasoma. Carapace areolate-rugose to punctate at apex; in posterior and dorsal views, apex terminating in two thick tubercles close together; in lateral view, carapace terminates in narrow sloping point below midline. Variation of paratype females. Metapleuron orange and black; lateral pronotum orange and black; HW 0.73-0.75 mm; HL 0.63 mm; HW/HL 1.16-1.2; BL 2.5-2.8 mm; FWL 2.13-2.3 mm; CL 1.16 mm; CW 0.32-0.36 mm; CL/CW 3.2-3.63. Paratype males. No males. Material examined. Holotype female: GUANACASTE, Arenales W side Volcan Cacao, 900 m, 1988-1989 (P. Hanson) [UWIM]. Paratype data: 1♀, same data as holotype. Remarks. Leptodrepana stasia is superficially similar to both L. ninae and L. conleyae in color and the presence of 2 tubercles on the apex of the carapace. However it may be easily distinguished from both of these species. In L. stasia the penultimate flagellomere is almost the same length as the ultimate flagellomere. The carapace is completely brownish black. In both L. ninae and L. conleyae the penultimate flagellomere is almost the same length as width and approximately half the length of the ultimate flagellomere. Additionally, the carapace of both species is yellowish white basally. Etymology. This species name is an arbitrary arrangement of letters to form a euphonious combination.
