Holotype female. BL 2.93 mm; FWL 2.4 mm; CL 1.28 mm; CW 0.4 mm; CL/CW 3.2. Description. Color. Head black, clypeus orangish brown with yellow at apical margin; mandibles mostly yellowish brown but blackish brown basally and apically; palpi yellowish white; antennae light brown with scape, pedicel and first 2 flagellomeres (basal) yellowish white; mesosoma black; fore leg with coxa, trochanter, and trochantellus white-yellow, femur brown, tibia and tarsus white-yellow, tarsal claw brown; middle and hind leg same as foreleg except tibia brown with basal band of yellowish white and tarsus brown; wings obfuscate except for circular area below stigma suffused with brown pigmentation and densely setose covering apical half of 1st sub marginal cell and most of 2nd submarginal cell; carapace mostly black, basal fourth of carapace yellowish white. Head. HW 0.9 mm; HL 0.68 mm; HW/HL 1.33; head densely pubescent; face, genae, vertex and ocellar triangle rugulose punctate; frons depressed and median carina largely obscured by rugulose sculpture; clypeus punctate and apical margin rounded; occipital carina complete. Mesosoma. Pronotum foveate; propleuron weakly areolate-rugose; mesoscutum densely pubescent and medially with irregular pitted grooves appearing areolate-rugose; notauli narrow and visible anteriorly; mesoscutal lobes rugulose-punctate; scutellar sulcus with five well-defined depressions, all longer than wide; scutellar disc pubescent and apparently granulate-punctate; mesopleuron anteriorly rugose, medially foveate, with wide deeply foveate groove at precoxal sulcus and foveolate-punctate below; mesopleural scrobiculate groove proximal metapleuron wide; propodeum coarsely areolate-rugose with distinct transverse carina raised into small and roughly equal medial and lateral flanges. Metasoma. Carapace areolate-rugose to weakly areolate-rugose at apex; in posterior view apex arched; in dorsal and lateral views, apex rounded. Variation. Paratype females.HW 0.9 mm; HL 0.68-0.7 mm; HW/HL 1.28-1.33; BL 2.93-3.06 mm; FWL 2.4 mm; CL 1.28-1.4 mm; CW 0.4-0.44 mm; CL/CW 3.18-3.2. Paratype males. No males. Material examined. Holotype female: GUANACASTE, Santa Rosa National Park, Bosque San Emilio 30-year-old, in clearing fully insolated part of the day, 300 m, 1. vi- 22.vi.1985 (I. Gauld & D. Janzen) [UWIM]. Paratype female: 1♀, same data except old forest more or less fully shaded as possible, 14. vi- 5.vii.1986. Remarks. Leptodrepana soussanae is superficially similar to L. thema but may be distinguished from this species by its robust body, over 3mm in length, uniform thickness of the flagellum and the densely setose circular area below the stigma suffused with brown pigmentation and covering apical half of 1st submarginal cell and most of 2nd submarginal cell. Leptodrepana thema is small, less than 2.5 mm. The flagellum appears slightly dilated medially. The wings are lightly suffused with yellowish brown pigment and do not have a densely setose darkly pigmented patch below the stigma. Etymology. This species name is a patronym in honor of a sister of SDD, Soussan Parker Dadelahi.
