Marma baeri Simon 1902

Marma baeri Simon, 1902 Figures 2–11, 57A, 58A 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). Description. Male (QCAZ). Total length: 3.12.

Palp: RTA finger-shaped (Figs 5D, 6C); embolic disc with both edges curved (Figs 5C, 7A); PED with approximately same length of exposed portion of embolic disc and emerging from the middle-distal part of embolic disc (Figs 5C, 7A); tip of embolus aligned with tip of PED (Figs 5C, 7F).

Color in alcohol (Figs 6 A–B): carapace as in male, abdomen ventrally with three dark longitudinal stripes and with dark brown edge with pale circles; legs: femur I with dark distal ring and proximal region with dark retroventral spot, II–III with dark distal ring and proximal region with incomplete dark ring (dorsal portion not totally colored), IV with dark distal ring and proximal region with dark proventral spot; tibia I–IV with proximal and distal dark ring; tarsus I–II without dark marks, III–IV with dark proximal ring. Epigyne (Figs 6 C–D, 7G–H, 10A–D): copulatory openings separated by approximately three times the girth of copulatory ducts, placed anteriorly to primary spermathecae; copulatory ducts short; proximal copulatory duct with approximately same length as distal section; primary spermathecae with initial portion dilated, tapering towards fertilization ducts; primary spermathecae laterally projected.
