Length. 13.2 mm. Head. Ocellar setae equal to or smaller than postoculars. Outer vertical seta of same size as postoculars. Orbital setae black. Four frontal setae situated below the dorsal limit of the lunule in lateral view. Genal setae black dorsally, yellow or white ventrally. First two rows of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 2 (anterior one shorter), intra-alars = 1 + 2 (anterior one shorter), supra-alars = 2 + 3, basal scutellars = 3. Prosternum and posterior surface of hind coxa with black setae.Antero-ventral scutellar setae black. Two katepisternal setae. Postalar wall with only black setae. Lower calypter with a central dark spot and a fringe of long hair-like setae along outer margin, extending to its posterior margin. Mid femur without a ctenidium. Antero-dorsal surface of mid tibia with a median seta and 1 apical seta. Hind tibia antero-dorsally with 1 seta in the basal third, 1 in the middle third and 1 preapical. Abdomen. Postero-ventral seams between T3/T4 and T4/T5 parallel. Posterior seam of T5 not projected posteriorly and ventrally. T5 with golden microtrichosity. Abdomen in lateral view with grey and golden microtrichosity. ST1+3 with yellow and white setae. Two lateral setae on each side of T4. Terminalia. ST5 orange. Medial margin of ST5 ∩-shaped. Inner margins of ST5 arms straight. Posterior margin of ST5 arms bent dorsally. Inner margins of ST5 arms with a patch of short setae on the median region. Syntergosternite 7+8 is longer than high in lateral view, orange, with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown or dark brown distally. Cercus in lateral view progressively narrowing towards the apex, dorsal margin with an undulation of the cuticle at about midlength, with an acute apex. Surstylus orange, triangular, with a rounded apex. Postero-distal surface less sclerotized (more smooth; lighter and more transparent colour) than the remaining surface. Pregonite tongue-shaped, curved with a rounded apex in lateral view. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta without demarcated connection with the phallic tube, as sclerotized as the phallic tube. Juxta with lateral plate, long, straight with a rounded apex in apical view. Juxtal lateral plate with spinose outer margin. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, visible in lateral view. Vesica composed of two plate-like structures on each side connected proximally.
