Abdomen ( Figs. 3D, E ): tergites yellow with black marks; T1 yellow, laterally black; T2 black, interrupted medially and sub-laterally in yellow; T3 black with two yellow spots, interrupted medially and sub-laterally in yellow, the yellow spots are anterior and sub-lateral to the large black areas; T4 yellow, caudal black band interrupted sub-laterally in yellow, the band enlarges medially similar to a triangle and reaches the anterior margin laterally; T5 yellow, one medial large droplet-shaped black spot, laterally brown; sternites light yellow; intersegmental membranes light. Terminalia ( Figs. 4 , 89B ): epandrium with approximately equal width and length, with microtrichia, with eight upper and two lateral setae; ventral lobe small, glabrous, with one long and one shorter apical setae. Cerci not fused to epandrium, with microtrichia, and with large setae, hypoproctal plate present, ventral cecal lobes present with two lateral and at least one apical seta each. Subepandrial sclerite wide. Surstylus connected to the epandrium, with prensisetae arranged in a dorsal line, at least five long outer setae. Hypandrium slightly longer than wide, squarish, smaller than epandrium. Pregonites narrow, fused laterally to the hypandrium, with a seta near its center, not fused medially. Postgonites short thick and straight, containing approximately three setulae near the fusion with pregonite. Phallapodeme is about the same length as the phallus, slightly curved ventrally. Body length: 1.94mm.
