Leptodrepana hansoni Dadelahi & Shaw sp. n. Figs 40-45

Diagnosis.

The carapace apex terminates in 2 points. Body brownish black and wings lightly pigmented. Shiny impunctate area medially on the mesopleuron, and presence of four well-defined depressions in the scutellar sulcus.

Holotype female.

BL 1.87 mm; FWL 1.47 mm; CL 0.84 mm; CW 0.32 mm; CL/CW 2.63.

Description.

Color. Head brownish black, mandibles yellow, brownish black apically and basally; palpi yellowish white; antennae brown scape, pedicel, and first flagellomere (basal) yellowish brown; mesosoma brownish black; legs yellowish brown except tibia of hind leg brown; wings lightly pigmented with yellowish brown venation; carapace brownish black.

Head. HW 0.575 mm; HL 0.375 mm; HW/HL1.53; face finely punctuate; genae, vertex and ocellar triangle rugulose-punctate; frons depressed, weakly punctate and median carina present; clypeus punctate and apical margin rounded; occipital carina complete; antennae with flagellum dilated medially so that flagellomeres 8-14 (basal) appear almost as long as wide, remaining flagellomeres decreasing in length apically.

Mesosoma. Pronotum foveolate antero-laterally to shiny and impunctate at propleural margin; propleuron areolate-rugose; mesoscutum medially with irregular pitted grooves between notauli so that area appears areolate-rugose; notauli narrow and visible anteriorly; median and lateral mesonotal lobes rugose-coarsely punctate; scutellar sulcus with four well-defined depressions, all longer than wide; scutellar disc punctate; mesopleuron anteriorly rugose foveolate, medially shiny and impunctate, narrow scrobiculate groove at precoxal sulcus, weakly punctate to impunctate 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 shiny punctate at apex; in posterior and dorsal views, apex with 2 tubercles; in lateral view, apex terminating in narrow point below midline.

Paratype females. No paratype females.

Variation of paratype males. Similar to female except antennae with 22 flagellomeres all longer than wide and tapering apically; propleural margin of pronotum rugose; mesoscutum coarsely punctate with medial area not sculpturally differentiated from mesonotal lobes; notauli indistinct; carapace apex rounded; HW 0.63 mm; HL 0.46 mm; HW/HL 1.36; BL 2.13 mm; FWL 1.87 mm; CL 0.96 mm; CW 0.32 mm; CL/CW 3.

Material examined.

Holotype female: PUNTARENAS, R. F. Golfo Dulce, 3 km SW Rincon, 10 m, ii.1993 (P. Hanson) [UWIM]. Paratype data: 1♂, SAN JOSE, Ciudad Colon 800 m, iv-v.1990 (L. Fournier).

Remarks.

Leptodrepana hansoni is superficially similar to L. kimbrellae . They are both similar in size, color, and the carapace apex terminates in two points. It may be distinguished from L. kimbrellae by the shiny impunctate area medially on the mesopleuron and the presence of four well-defined depressions in the scutellar sulcus. Additionally, the carapace of L. hansoni is entirely brownish black. The mesopleuron of L. kimbrellae is deeply foveate medially. The scutellar sulcus has six well-defined depressions. The posterior margin of the basal yellowish white patch is usually deeply notched.

Etymology.

This species name is a patronym for Professor Paul Hanson in appreciation for his extensive efforts in collecting braconids of all shapes and sizes.
