Diagnosis.

In posterior view apex terminating in two points deeply arched between; in dorsal view, apex terminates in two points visible below rounded carapace dorsum. The mesopleuron is deeply foveate medially. The scutellar sulcus has 6 well-defined depressions. The posterior margin of the basal yellowish white patch on the carapace is usually deeply notched. Body mostly blackish brown but carapace with basal third yellowish white, posterior margin of this area is medially deeply notched giving the basal area a bi-lobed appearance.

Holotype female.

BL 2.46 mm; FWL 2.06 mm; CL 1.16 mm; CW 0.4 mm; CL/CW 2.9.

Description.

Color. Head blackish brown, mandibles mostly yellowish brown but blackish brown basally and apically; palpi yellowish white; antennae brown darkest apically with scape, pedicel and first flagellomere (basal) yellow; mesosoma black; legs yellowish orange with a narrow basal band of white on tibiae of hind and middle legs; wings suffused with light brown pigmentation and appear slightly dusky with brown venation, parastigma and vein 1M lighter in color; carapace blackish brown with basal third yellowish white, posterior margin of this area is medially deeply notched giving the basal area a bi-lobed appearance.

Head. HW 0.75 mm; HL 0.63 mm; HW/HL 1.2; face, genae, vertex and ocellar triangle rugulose-punctate; frons depressed, coarsely punctate with fine parallel lineation to median carinae; clypeus punctate and apical margin rounded; occipital carina complete; antennae with a slightly swollen appearance medially.

Mesosoma. Pronotum foveate antero-laterally to weakly areolate-rugose at propleural margin; propleuron weakly areolate-rugose; mesoscutum medially with irregular parallel pitted grooves between notauli difficult to distinguish and appears areolate-rugose; notauli narrow and visible anteriorly; medial mesonotal lobe granulate-punctate, lateral mesonotal lobes rugose-coarsely punctate; scutellar sulcus with 6 well-defined depressions, all longer than wide; scutellar disc coarsely punctate; mesopleuron anteriorly rugose, medially deeply foveate especially at and posterior to precoxal sulcus; propodeum coarsely areolate-rugose with distinct transverse carina raised into small and roughly equal medial and lateral flanges.

Metasoma. Carapace areolate-rugose basally, graduating to shiny and weakly punctate at apex; in posterior view apex terminating in two points deeply arched between; in dorsal view, apex terminates in two points visible below rounded carapace dorsum; in lateral view, apex terminates in sloping point below midline; ventral cavity almost reaching apex.

Variation of paratype females. Color: clypeus orange; scape pedicel flagellum uniformly brown; legs yellowish white to orange/brown and basal tibial bands appear faint on lighter colored legs; carapace with basal yellowish white area weakly to deeply bi-lobed; parastigma and vein 1M same color as remaining venation; HW 0.63-0.78 mm; HL 0.53-0.63 mm; HW/HL 1.2-1.25; BL 1.7-2.4 mm; FWL 2.1-2.9 mm; CL 0.9-1.2 mm; CW 0.32-0.44 mm; CL/CW 2.4-2.8.

Variation of paratype males. Similar to females except clypeus yellow/orange; antennae with 24 flagellomeres, tapering apically; flagellum yellowish white; mesopleuron coarsely punctate medially; in posterior view, carapace apex terminating in two points shallowly arched between; ventral cavity distal carapace apex. HW 0.58-0.63 mm; HL 0.48-0.5 mm; HW/HL 1.2-1.3; BL 1.9-2.1 mm; FWL 1.7-1.9 mm; CL 1.0 mm; CW 0.32 mm; CL/CW 3.13.

Remarks.

Superficially Leptodrepana kimbrellae is most similar to L. gauldilox . Both species are similar in color and in posterior and lateral views, have two tubercles on the carapace apex. However, upon examination they are easily distinguished from one another. Leptodrepana kimbrellae is small, less than 2.5 mm and in lateral view, the carapace is at the most 3 times as long as wide. Leptodrepana gauldilox is large, more than 3.0 mm and in lateral view, the carapace is more than 3.5 times as long as wide. Leptodrepana kimbrellae is also similar to L. hansoni in size, color, and presence of two tubercles on the carapace apex, visible in posterior and dorsal views. Leptodrepana kimbrellae may be easily distinguished from this species. The mesopleuron is deeply foveate medially. The scutellar sulcus has six well-defined depressions. The posterior margin of the basal yellowish white patch on the carapace is usually deeply notched. Leptodrepana hansoni has a shiny impunctate area medially on the mesopleuron and the scutellar sulcus has four well-defined depressions. Additionally, the carapace of L. hansoni is entirely brownish black.

Etymology.

This species name is a patronym named in honor of a sister of SDD, Sarah Kimbrell Migrants.
