Paralophostica centralis Soares & Camargo, 1948: 397   [Lectotype ♁, here designated: BRAZIL: Goiás: Aragarças [15°53’40.6”S, 52°15’20.9”W], leg. H. Sick, 15–22.IX.1946, deposited in MZUSP E-740/C-1334]; paralectotype ♀ and paralectotype ♁: Same data as lectotype, deposited in MZUSP E-740/C-1335, examined]. Syn. nov   .

Note. Marma rosea   was previously considered one of the synonyms of M. nigritarsis   . The difference between these species was explained in the diagnosis of M. nigritarsis   above. The comparisons among the female types of M. rosea   ( Figs 49 View FIGURE 49 D–F) and Paralophostica centralis   ( Figs 49 View FIGURE 49 A–C) provided some evidence that both belong to the same species. However, the lack of a topotypic male type for M. rosea   precludes comparisons and makes it difficult to provide an accurate result. Despite this, because of the many morphological similarities among their epigynes ( Figs 49C, F View FIGURE 49 ) we decided to synonymize these species. The male is described based on a freshly collected specimen ( Figs 48 View FIGURE 48 E–G) and the female based on the well-conserved paralectotype of P. centralis   ( Figs 49 View FIGURE 49 A–C).

Revised diagnosis. Among all Marma   species, M. rosea   shares more similarities with M. argentina   and M. spelunca   sp. nov. The males of these species have a thick embolic disc, with both borders curved ( Figs 44C View FIGURE 44 , 46A View FIGURE 46 , 48C View FIGURE 48 , 50A View FIGURE 50 , 53C View FIGURE 53 , 55A View FIGURE 55 , 57 View FIGURE 57 G–I), and females have very long copulatory ducts that encircle the primary spermathecae and almost touch each other ( Figs 45F View FIGURE 45 , 46D View FIGURE 46 , 49F View FIGURE 49 , 50G View FIGURE 50 , 54C View FIGURE 54 , 55G View FIGURE 55 , 58 View FIGURE 58 I–K). However, the male of M. rosea   differs by having the retrolateral border of the embolic disc with more accentuated curvature than the prolateral edge ( Figs 48C View FIGURE 48 , 50A, C View FIGURE 50 , 57H View FIGURE 57 ), whereas both borders have approximately symmetrical curvature in M. argentina   ( Figs 44C View FIGURE 44 , 46A View FIGURE 46 , 57G View FIGURE 57 ) and M. spelunca   sp. nov. ( Figs 53C View FIGURE 53 , 55A View FIGURE 55 , 57I View FIGURE 57 ). Also, the females of M. rosea   differ from those of M. spelunca   sp. nov. by having smaller copulatory openings ( Figs 49C View FIGURE 49 , 54C View FIGURE 54 ), and they differ from those of M. argentina   by having the primary spermathecae without their initial region expanded to lateral side ( Figs 46C View FIGURE 46 , 50F View FIGURE 50 , 58 View FIGURE 58 I–J).
