Marma baeri Simon, 1902: 376 (Holotype ♁: ECUADOR: Túmbez [00°49’01.2”N, 78°21’00.2”W], leg. G.A. Baer, deposited in MNHN, collection of E. Simon; allotype ♀, same data as holotype, both examined by photographs); Galiano, 1962: 36, pl. I, figs 1–5; Galiano, 1963: 395, pl. XXVIII, figs 7–10.
Note. Both sexes are redescribed based on newly collected specimens. Photographs of the type specimens were provided by MNHN (Figs 4 A–G).
Diagnosis. The males of M. baeri are most similar to those of M. linae sp. nov. by having a short process on the embolic disc (PED; 5C, 7A, 13C, 15A), but differ by having a thicker embolic disc (Figs 57 A–B). Besides, the embolus shaft (e) in M. baeri emerges from a less proximal portion of embolic disc and is consequently shorter than the embolus of M. linae sp. nov. (best visualized cleared in clove oil; Figs 7F, 9C, 15E, 16A). The females of M. baeri differ from those of M. linae sp. nov. by having the copulatory openings separated by approximately three times the girth of the copulatory duct and by its placement anterior to the primary spermathecae (Figs 6C, 7 G–H, 58A), whereas they are very close (separated by less than 1/2 their diameter) and placed at the same level of the primary spermathecae in M. linae sp. nov. (Figs 14C, 15 F–G, 58B). Also, females of M. baeri have the distal portion of the primary spermathecae projecting laterally (Figs 6C, 7H, 58A), whereas they project anteriorly in M. linae sp. nov. (Figs 14C, 15G, 58B). Females of M. baeri are also very similar to those of M. femella, both with copulatory openings far from each other and the distal portion of primary spermathecae projecting laterally (Figs 58A, D). However, in M. baeri the initial portion of spermathecae is dilated, whereas the spermathecae of M. femella have an elliptical shape (Figs 58A, D).
