Diagnosis.

This species closely resembles Margattea transversa sp. nov., but they can be distinguished by the following characteristics: 1) Left phallomere of the former with three long spines, while the latter with four long spines; 2) In the former, median phallomere apex with a slightly curved spine, while the median phallomere apex of latter with a distinct curved spine. In addition, this species is also similar to M. nimbata (Shelford, 1907) in general appearance, but it can be differentiated from the latter by the following characters: 1) median phallomere base with a curved spine, while in the latter, with two curved spines; 2) A long piece of bone extends from the right side of the accessory structure, while absent in the latter; and 3) left phallomere with three long spines; the latter with two long spines.

Measurements

(mm). Male (n = 5), pronotum: length × width 2.7-2.8 × 3.1-3.6, tegmina length: 10.4-12.6, overall length: 12.8-14.1.

Male. Coloration: body pale yellowish-brown with yellowish-brown (Fig. 9A, B). Face dark yellowish-brown. Interocular space with a brown band. Ocelli spots white. Antennae yellowish-brown. Clypeus pale brown (Fig. 9C). Maxillary palps light linen-colored (Fig. 9E). Pronotal disc light linen-colored with brown stripes and two lateral borders yellowish-white (Fig. 9D). Tegmina pale yellowish-brown, wings medium brown (Fig. 9F, G). Abdomen cream-colored to pale brown. Cerci yellowish brown (Fig. 9K). Styli faint yellow (Fig. 9M). Head: vertex slightly exposed, distance between interocular shorter than antennal socket space (Fig. 9C). Pronotum nearly trapezoidal, broader than long, the widest part after the midpoint, the front and posterior margins nearly straight, and the postero-lateral angle blunt and round; disc with symmetrical irregular maculae (Fig. 9D). Third and fourth palpi of approximately same length, both obviously longer than fifth palp, fifth palp obviously expanded (Fig. 9E). Tegmina and wings: tegmina and wings fully developed, both extending beyond the end of abdomen (Fig. 9A, B). Tegmina with ScP simple, R multi-branched, M straight with seven complete branches. Hind wings with ScP and RA expanded at apex; M straight and simple without branches; CuA with five complete branches (Fig. 9F, G). Legs: anteroventral margin of front femur type B2 (Fig. 9H). Pulvilli present on four proximal tarsomeres. Tarsal claws symmetrical and specialized, inner margin serrated, arolia present (Fig. 9I). Abdomen and genitalia: eighth abdominal tergum specialized with a tuft (Fig. 9J). Supra-anal plate transverse, posterior margin convex. Paraprocts simple, splitting into two pieces, apex with tufts (Fig. 9K). Subgenital plate symmetrical. Styli similar, slender, distinctly separated; interstylar region slightly convex (Fig. 9M). Left phallomere complex, irregular bone-shaped, with three long spines (Fig. 9L). Median phallomere slender rod-shaped, apex with a slightly curved spine; accessory structure arched, a long piece of bone extends from right side of accessory structure (Fig. 9M). Hook phallomere on right side, apex curved inwards with a short spine (Fig. 9N).

Female similar as male.
