Note. The species Agelista rosea Mello-Leit   „o, 1941, Thysema dorae Mello-Leit   „o, 1944 and Paralophostica centralis Soares & Camargo, 1948   were synonymized with Marma nigritarsis   by Galiano (1962). Ocnotelus argentinus Mello-Leit   „o, 1941 was also synonymized with M. nigritarsis   by Galiano (1981). These synonymies are rejected herein.

We concluded, by comparisons among the types of the previously synonymized species ( Figs 35 View FIGURE 35 A–I, 45A–F, 48A–D, 49) with the material provided by MPEG, MACN, UFMG and IBSP, that the synonymies of Pseudoamphidraus variegatus Caporiacco, 1947 and Marma trifidocarinata Caporiacco, 1947   with M. nigritaris   should be maintained. In addition, we concluded that M. rosea   (Mello-Leit„o, 1941) and M. argentina   (Mello-Leit„o, 1941) are morphologically different from M. nigritarsis   , and therefore, these species are revalidated and redescribed.

We provide new diagnostic illustrations based on freshly collected material for the male ( Figs 37 View FIGURE 37 A–E, G) and based on the holotype of Marma trifidocarinata   for the female ( Figs 37 View FIGURE 37 H–I).

Revised diagnosis. Among all Marma   species, M. nigritarsis   shares more similarities with M. pipa   sp. nov. The males of both species have an embolic disc with similar width, with straight prolateral border and curved retrolateral border ( Figs 25C View FIGURE 25 , 27A View FIGURE 27 , 36C View FIGURE 36 , 37A View FIGURE 37 , 57C, 57E View FIGURE 57 ). In the females, the copulatory ducts do not touch each other and encircle the primary spermathecae ( Figs 26 View FIGURE 26 C–D, 27F–G, 35H–I, 37H–I, 58E, G). The males of M. nigritarsis   differ from those of M. pipa   sp. nov. by having a longer embolus and a longer process on the embolic disc (PED; Figs 57C, E View FIGURE 57 ), and the females differ by having a homogenous diameter along the primary spermathecae (broad proximally and narrow distally in M. pipa   sp. nov.; Figs 58E, G View FIGURE 58 ).

Comparisons among the species revalidated in this study: Males of M. nigritarsis   differ from those of M. rosea   by having the embolic disc with a smaller process and its retrolateral edge with less pronounced curvature ( Figs 36C View FIGURE 36 , 37A, C View FIGURE 37 , 48C View FIGURE 48 , 50A, C View FIGURE 50 , 57E, H View FIGURE 57 ). Also, males of M. nigritarsis   have the prolateral border straight in the embolic disc ( Figs 36C View FIGURE 36 , 37A View FIGURE 37 , 57E View FIGURE 57 ), whereas it has a more pronounced curvature in M. rosea   ( Figs 48C View FIGURE 48 , 50A View FIGURE 50 , 57H View FIGURE 57 ) and M. argentina   ( Figs 44C View FIGURE 44 , 46A View FIGURE 46 , 57G View FIGURE 57 ). Besides, the process of the embolic disc (PED), embolus and cymbium are smaller (proportionally when compared to the bulb) in M. nigritarsis   than in M. argentina   ( Figs 57E, G View FIGURE 57 ). Females of M. nigritarsis   differ by having the copulatory ducts far from each other ( Figs 35 View FIGURE 35 H–I, 37H–I, 58G), whereas they are close (touching each other) in M. rosea   ( Figs 49C, F View FIGURE 49 , 50 View FIGURE 50 F–G, 58J) and M. argentina   ( Figs 45C, F View FIGURE 45 , 46 View FIGURE 46 C–D, 58I). In addition, the primary spermathecae of M. nigritarsis   are approximately straight, whereas they are accentuated arched in M. argentina   ( Figs 58G, I View FIGURE 58 ).
