Figs 5 CDH, 7F–H, 9A–G.

Brownish ochraceous. Crown with short transverse spot on inner margin of eye, one spot close to median line dark fuscous. Transverse line on frontoclypeus and median line on clypellus brownish, lateral sutures and oblique spot below antennal insertion, dark brown. Pronotum with anterior submarginal row of fuscous spots, one black spot ventrad of lateral marginal carina. Mesoscutum with basal triangles brownish. Structure as in generic description. Profemur with setal row anterodorsal (AD) well developed with 21 short setae; setal row AV with 21 short, peg-like setae present in proximal half, AV1 hair-like, well developed at distal end nearer ventral margin; intercalary row (IC) with about 9 hair-like setae. Metabasitrsomere with 5 platellae on apical transverse row flanked by one seta on either side; plantar surface with 5 stout setae in a row.

Male genitalia. Pygofer rounded posterodorsally with blade-like ventral process exceeding pygofer, and acuminate at apex, short setae at midlength in addition to a few scattered setae, tergum sclerotized and dorsally not incised; anterior margin with well developed apodeme. Subgenital plate rather triangular with rounded apex, with one row of macrosetae on lateral margin and a few hair-like setae on lateral area dorsally. Style with anterior margin about 0.66 as wide as total length. Aedeagus with dorsal apodeme well developed, with pair of slender processes about 0.66 as long as shaft; shaft tubular, with subapical pair of processes; gonopore apical.

Female. Unknown.

Measurements. Male 5.4–5.6 mm long, 1.4 mm wide across eyes and 1.6 mm wide across posterolateral angles of pronotum.

Material examined. INDIA: Andaman & Nicobar Is.: HOLOTYPE ³, North Andamans : Diglipur, 13 o 14.9’ N, 92 o 58.37 E, 15 m, 23.iv.2014, light trap, Yeshwanth, H.M. ( UASB). PARATYPE, 1 ³, data same as holotype ( UASB) .

Etymology. The specific epithet refers to the name of the islands where the species was collected.

Remarks. Among the three new species dealt with here this species is darker and has more or less rectangular rather than circular spots on the crown which are almost touching the inner margin of the eye and with a transverse brown fascia between the spots on the crown and an anterior submarginal row of fuscous spots on the pronotum.
