Redescription. Antenna ( Fig. 48, from female paratype) with postpedicel somewhat yellow with obtuse apex. Thorax ( Figs 46–47). Mesopleuron yellowish brown, brown pruinose, except anepisternum with grey pruinescence anterodorsally; katatergite somewhat yellow with sparse grey pruinescence. Mediotergite mostly brown pruinose. Legs ( Fig. 46) dark brown, except apices of trochanters and femora and bases of tibiae yellow; femora with grey pruinescence on the posterior face. Wing ( Fig. 49, from female paratype). Length 8.0 mm. LTC/ LFC = 1.4. Membrane entirely hyaline. Abdomen ( Fig. 47) dark brown to black, all tergites with interrupted bands of light brown pruinescence posteriorly. Tergite 6 and sternites 6 and 7 as in Fig. 51. Terminalia. Syntergosternite 8 with a relatively small circular membranous area ( Fig. 52). Epandrium yellow, moderately inflated. Surstyli ( Figs 53–54) subsymmetrical, apparently fused with epandrium, elongated ventrally but just slightly surpassing lateral margins of epandrium ( Figs 55–56). Phallic guide ( Figs 57–59) short, almost as long as hypandrium; sinuous in ventral view ( Fig. 58) and with a pronounced subapical concavity in lateral view ( Fig. 59). Hypandrium with distinct lobes near base of phallic guide ( Fig. 57). Basal processes of phallus large, surpassing the hypandrium width ( Figs 57, 59). Phallus with very small projections apically ( Fig. 60). Ejaculatory apodeme as in Fig. 61.

Female known and described ( Rafael & Rosa, 1991: 343). Frons and face with grey pruinescence. Wing entirely hyaline. Abdominal tergites with interrupted bands of grey pruinescence posterolaterally.
