Figs. 3 L–M, 6 L–M, 9 J–K, 10 L, 13 M–P, 51 A–H.

Male and female. Male much darker than female. Head and legs ochraceous, pronotum and wings dark brown with ochraceous spots. Eyes reddish brown, ocelli black. Mesonotum black with faint ochraceous spots, lateral margins brownish ochraceous. Thoracic sternites and pleurites largely black with broad ochraceous margins (Figs. 3 L–M, 6 L–M, 9 J–K). Female seventh sternite with posterior margin broadly convex in middle (Fig. 10 L).

Male genitalia. Pygofer broadly triangular, sparsely setose apically with caudodorsal process long, straight, blade-like, pointed apically (Fig. 51 H). Subgenital plate long, broad in basal ¾, then narrowed and of uniform width with rounded apex (Fig. 51 E). Style short, broad at base, apophysis slender and digitate (Fig. 51 F). Connective longer than wide at base, median longitudinal ledge well developed, complete (Fig. 51 G). Aedeagus with two apical and one subapical moderately long subequal processes, lateral margin of shaft with seven spine-like setae near middle, gonopore at midlength of shaft, dorsal apodeme sinuate (Figs. 51 A–D).

Female genitalia. Valvula I sculptured in apical ¼ (Figs. 13 M–N). Valvula II with basal three teeth prominent and remaining five teeth less so, each tooth triangular without secondary tooth, dorsal teeth in apical 1/3 (Fig. 13 O–P).

Measurements. Male 7.7−7.8 mm long, 2.0 mm wide across eyes and 2.4 mm across posterolateral angles of pronotum. Female 8.1 mm long, 2.1 mm wide across eyes and 2.5 mm across posterolateral angles of pronotum.

Material examined. HOLOTYPE ♂, INDIA: Andaman & Nicobar: South Andaman: Jirkatang 11 0 49’53.4” N, 92 0 39’17.4” E, 2.6m, 19.iv.2014, Sweep net, Yeshwanth, H.M. (UASB) . PARATYPES: INDIA: Andaman, 1 ♀, Mt. Harriet, 11 0 44’ N, 92 0 39’ E, 0.6m, 11.iii.2012, David, K.J. (UASB) .

Etymology. The species is named after the type locality and is noun in apposition.

Remark. W. andamana sp. nov. is similar in male genitalia features to W. webbi, and can be distinguished from the latter by the two apical and one subapical aedeagal processes (one apical process in W. webbi), by a series of short spine-like setae medially on the aedeagal shaft, and the subgenital plate not as narrowed distally.
