Platyretus marginatus Melichar

( Figs 13–19 )

Platyretus marginatus Melichar 1903: 174 –175. Distant 1908: 289 –290, Fig. 184. Type Ψ, SRI LANKA [MMB, examined]

Color and external characters as in the generic description.

Male genitalia: Subgenital plates rather rounded laterally and caudally. Style with slightly curved slender apophysis with hair-like setae basally and stout setae apically, preapical lobe poorly developed. Aedeagus similar to previous species, but apex of shaft, with dorsal acute hook-like projection, in lateral view.

Female genitalia: Median lobe of seventh sternite with a strong median concavity.

Measurements: Male 6.2–6.6 mm long, 1.6 mm wide across eyes. Female 6.4–6.6 mm long, 1.6 mm wide across eyes.

Material examined: SRI LANKA: Type, 1 Ψ, ( MMB). Other material: SRI LANKA: 1 ɗ, Peradeniya, i.1905; 1 ɗ, Kala Olya, xii. 1905; 1 Ψ, Central Province, Kandy Distr., Talwatte, 500 m, 3.xi.1995, M. Shaffer ( BMNH).

Remarks: There are a few specimens from India (Karnataka: 1 ɗ, 1 ɗ, 10 Km SE Magadi, 16.viii.1977, C.A. Viraktamath; Maharashtra: 1 ɗ, 2 Ψ, Matheran, 915 m, 23.xi.1977, C.A. Viraktamath (UASB)) that closely resemble specimens of this species from Sri Lanka but have a slightly undulate outer margin of the style apophysis. This species can be recognized from other species of Platyretus by the poorly developed style apophysis.
