Sisyra minuta Esben-Petersen, 1935:152 View in CoL [description]; Parfin & Gurney 1956:478 [revision]; Penny 1981:164 [record]; Flint 2006:281 [record].

Remarks. Esben-Petersen (1935) described this species based on a male specimen from “Taderinha”, Brazil, which according to Parfin & Gurney (1956) is a misspelling to “Taperinha” (Amazonas, Brazil). Later, Penny (1981) and Flint (2006) recorded S. minuta from Manaus city, Amazonas state, Brazil, with specimens from Adolpho Ducke Reserve ( Fig. 2 View FIGURES 1–7 ).

Esben-Petersen (1935) described the species as small, with yellowish brown forewing and hyaline hind wing ( Figs 8–9 View FIGURES 8–11 ), without providing a description of the male genitalia. Parfin & Gurney (1956) and Penny (1981) illustrated and described the male genitalia of the holotype; however, important structures were not highlighted. Therefore, additional illustrations of this species are here presented in order to complement previous illustrations of the male genitalia ( Figs 10–11 View FIGURES 8–11 ).

The remarkable characteristic of S. minuta is the short male gonocoxite 9, with the apex sharply pointed dorsoventrally; “beak-like” as stated by Penny (1981). The specimen analyzed in this paper has differences in the male genitalia from what is described and illustrated in the literature. These differences could be attributed to the angle of the genitalia during the illustration or drawing styles. The primary differences are in the gonostyle 11, which has almost same size than the apex, with a lateral “finger-like” joint to the gonocoxite 9 ( Fig. 11 View FIGURES 8–11 ). In addition, the sharply pointed apex of gonocoxite 9 has a second projection on the inner region, which bears a distal seta ( Fig. 10 View FIGURES 8–11 ). Parfin & Gurney (1956) illustrated the male genitalia of S. minuta showing a small gonostyle 11, without lateral joint, and the sharply pointed apex of the gonocoxite 9, without an inner projection. Penny (1981) did not identify the inner small projection of the gonocoxite 9, but highlighted three sharply pointed structures, which could be interpreted as the gonostyle 11, the gonocoxite 9 apex and the lateral joint of the gonostyle 11 with gonocoxite 9, which could appear as a sharp projection depending on the view.
