(Figs. 110, 111)  
 Description. Male. Length. 7.61 mm. Head. Ocellar setae stronger than postoculars. Outer vertical seta stronger than postoculars. Orbital setae black. Three 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 = 2 + 3, intra-alars = 2 + 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. Three katepisternal setae. Postalar wall with only black setae. Lower calypter with a central dark spot, without a fringe of long hair-like setae along outer margin. Mid femur without a ctenidium. Hind femur with a row of anteroventral and a row of postero-ventral setae, male hind femoral organ with setae very closely set in a patch. Anterodorsal surface of mid tibia with 2 median seta and 1 apical seta. Anterior surface of hind femur with a black patch of setae near apex. 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 and grey microtrichosity. Abdomen in lateral view with grey microtrichosity. ST1+3 with only black setae. Three or 4 lateral setae on each side of T4. Terminalia. ST5 black. Medial margin of ST5 ∩- shaped. Inner margins of ST5 arms straight. Inner margins of the of ST5 arms without patches of setae. Syntergosternite 7+8 as long as high in lateral view, black, with golden and grey microtrichosity. Epandrium bright orange. Cercus orange. Distal half of the dorsal margin of cercus slightly curved in lateral view. Cercal apex acute in lateral view. Surstylus orange, triangular, with a rounded apex. Postero-distal surface of surstylus equally sclerotized as the remaining surface. Pregonite triangular, becoming narrower towards the apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta with juxtal lateral plate with three juxtal horns. Basal horn coiled around the axis of the juxtal lateral plate, as long as the others horns and not clearly separated from the remaining juxta. The bifurcation giving origin to the juxtal lateral plates is deep and leaves the lateral plates not very close to each other. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft. Short vesica composed of one entire plate without demarcated connection with the distiphallus.
