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 D–F) and Paralophostica centralis (Figs 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) we decided to synonymize these species. The male is described based on a freshly collected specimen (Figs 48 E–G) and the female based on the well-conserved paralectotype of P. centralis (Figs 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, 46A, 48C, 50A, 53C, 55A, 57 G–I), and females have very long copulatory ducts that encircle the primary spermathecae and almost touch each other (Figs 45F, 46D, 49F, 50G, 54C, 55G, 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, 50A, C, 57H), whereas both borders have approximately symmetrical curvature in M. argentina (Figs 44C, 46A, 57G) and M. spelunca sp. nov. (Figs 53C, 55A, 57I). Also, the females of M. rosea differ from those of M. spelunca sp. nov. by having smaller copulatory openings (Figs 49C, 54C), and they differ from those of M. argentina by having the primary spermathecae without their initial region expanded to lateral side (Figs 46C, 50F, 58 I–J).
