Córrego Campo do Meio (22°41’28”S, 45°28’26”W), 1 f, 11/I/2006, MRS; 1 m, 18/XI/2007, LSL, RM, LCP.

Description of Female. Colour pattern similar to that of the males, but the head may present more extensive lighter areas. Forewing length 14.2 to 15.0 mm (n=5). The subgenital plate has only the median lobes ( Fig. 30 View FIGURES 30 – 31 ). St9 presents a somewhat rounded setal patch; the hind margin varies from broadly concave to broadly convex with narrow, dense setal fringe; posterior marginal sclerotization weak.

Egg ( Fig. 31 View FIGURES 30 – 31 ). Very long, 0.51–0.53 x 0.20–0.22 mm, n=6.

Remarks. The species was described from a single male from Campos do Jordão. Forewing length of the holotype is 10.6 mm, while lengths of the examined males vary from 10.9 to 12.0 mm (n=6). New figures of the head and pronotum ( Fig. 26 View FIGURES 26 – 29 ), male hammer ( Fig. 27 View FIGURES 26 – 29 ) and penial armature ( Figs 28–29 View FIGURES 26 – 29 ) are presented.

Seven of 10 specimens were collected during the day using a net or a beating sheet, one was caught in a Malaise trap, and one was reared from a nymph. The species is seemingly not attracted to lights. In PECJ it was collected from September to November.
