Pleural sclerites whitish with an orangish tinge, except for a brown mark on antepronotum anteriorly, a brown mark dorsally on laterotergite, mediotergite brown. Scutum with one pair of prescutellars medially along dorsocentral line, two prescutellars at each lateroposterior corner. Antepronotum with two long bristles and some additional long and short setae, proepisternum bare. Halter light brown, knob darker. Legs. Fore coxa light brown anteriorly and whitish posteriorly, mid coxa whitish with a brownish tinge antero-distally, hind coxa whitish; hind femur ochre-yellow, tibia and tarsus light greyish-brown, tarsomeres darker towards tip [holotype fore and mid femora, tibiae and tarsi missing]. Hind tibia inner spur 3.6× longer than tibia width at apex. Wing (Fig. 83C). Membrane with dark brown marks over sc-r, first sector of Rs, R 4 and along bM, yellowish along anterior margin. C produced beyond tip of R 5 for about a fifth of distance to M 1; Sc complete (visible on phase contrast), reaching C slightly before level of origin of Rs, sc-r present, reaching bR before of origin of Rs for a distance equal to first sector of Rs. R 1 reaching C at distal fourth of wing; R 5 reaching C before level of tip of M 1; R 4 present, slightly oblique, very close to base of Rs, cell r1 trapezoid, short, anterior margin of cell r1 1.1× longer than length of R 4; first sector of Rs 0.70× r-m length. False medial vein conspicuous, sclerotized. M 1+2 3.7× r-m length; bM 6.2× length of first sector of Rs. First sector of CuA 1.1× longer than second sector. M 4 almost straight on distal half. Cubital pseudovein sclerotized to mid of second sector of CuA; CuP faint, not even reaching origin of M 4. Anal fold faint. Wing margin gently emarginated at tip of CuA. No ventral macrotrichia on veins, dorsal macrotrichia on distal third of Sc before sc-r, entire length of bR, R 1, second sector of Rs, most of M 1 and M 4, distal 2/3 of M 4, and entire length of CuA; sc-r, most of Sc, base of bR, first sector of Rs, R 4, r-m, bM, and CuP entirely devoid of macrotrichia. Abdomen. Tergite 1 light brown, tergites 2–3 and 5–6 with a dark brown medial band, a cream-yellow anterior band extending posteriorly along laterals on tergites 2–3 and with a cream-yellow mark on anterolateral corner, tergite 4 cream-yellow with a small median brown mark ochre-yellow.

Tergite 9+10 with a slender medial connection between a pair of short lateral lobes with microtrichia and setae, laterally a pair of short digitiform projections, each with a long seta at tip. Cercomere 1 relatively short, widening to apex, 1.2× longer than cercomere 2, both covered with microtrichia and short setae. Male. Unknown. Material examined Holotype: female, ZRCBDP 0048487, Nee Soon (NS2), swamp forest, 13.jun.12, MIP leg. (slide-mounted). Etymology The species epithet refers to Ciṅkappūr (சிங்கப்பூர்), the Tamil transcription for Singapore. The noun is used in apposition. Remarks There are features in the female morphology of this species that allow the presentation of a diagnosis. This includes the color pattern on the head and thorax, the small r4 cell, the wing markings, and the shape of the terminalia sclerites.
