Amazunculus claripennis Rafael & Rosa, 1991: 343 , figs 26–31, 35; De Meyer, 1996: 44 (cat.); Galinkin & Rafael, 2008: 522, figs 14, 15; Rodriguez & Rafael, 2012: 14; Marques & Rafael, 2018.

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. Ovipositor. OL: 1.3 mm; PL: 0.9 mm; B: 0.4 mm. Base dark brown to black, grey pruinose. Piercer yellowish brown, distal part shining and nearly straight, just slightly curved at tip.
