Material examined. 2♁♁ BRAZIL, Rio de Janeiro state, Nova Friburgo, Pico São João , 26.i.1996, (type locality, 1500m asl), Mielke leg., ABMM .

Known distribution. Brazil (Nova Friburgo, Rio de Janeiro state).

Diagnosis and remarks. This is a very rare and unique species, which has been collected on only two occasions (1990 and 1996), not seen ever since, and assessed as Data Deficient in the IUCN Red List ( Vilela & Guillermo-Ferreira 2021h). The following character combination distinguishes this species from the remainder of Group A species: BP uniquely consisted of a long, narrow ventral branch ( Fig. 51c–d View FIGURE 51 ); upper plate small, shaped like an inverted triangle, bearing a small row of teeth posteriorly; ridge fused with ML up to 1/2 of lower plate ( Figs. 51c–d View FIGURE 51 ).
