Marma abaira sp. nov.

Figures 18–19 , 58C

Etymology. The specific epithet is a noun in apposition that refers to the type locality.

Diagnosis. Among all currently known females of the genus, M. abaira sp. nov. ( Figs 18 C–D) is most similar to M. baeri ( Fig. 6C ) and M. femella by having the copulatory openings far from each other and the copulatory ducts not encircling the primary spermathecae ( Figs 58A , C–D). However, M. abaira sp. nov. can be distinguished from M. baeri by having elliptical primary spermathecae (the proximal portion is dilated, and the distal portion is narrow in M. baeri ; Figs 6C , 18 C–D, 58A, C) and by having copulatory openings closest to each other ( Figs 58A, C ). Marma abaira sp. nov. can be distinguished from M. femella by having the copulatory openings placed more anteriorly, and the primary spermathecae projecting to the anterior side (laterally projecting in M. femella ; Figs 18 C–D, 58C–D). Male unknown.

Description. Female (Holotype, UFMG 15049). Total length: 4.35. Carapace 1.97 long, 1.34 wide, 0.95 high. Ocular quadrangle 0.97 long. Anterior eye row 1.26 wide, posterior 1.08 wide. Legs 4312. Length of legs: I 2.98 (1.04 + 1.12 + 0.82); II 2.89 (1.05 + 1.04 + 0.80); III 3.81 (1.30 + 1.36 + 1.15); IV 3.87 (1.28 + 1.26 + 1.33).

Leg macrosetae: Femur I d1-1-1, p1di, r0; II d1-1-1, p1di, r1di; III d1-1-1, p1di, r0 (or r1di); IV d1-1-1, p1di, r0. Patella I–II 0, III–IV p0, r1. Tibia I p0-1-0, r0, v2-2-2; II p0-1-0, r0, v1r-2-2; III p0-1-1-0, r0-1-1-0, v1p-0-0-1p (or v1p-0-0-2); IV p0-1-1-0, r0-1-1-0, v1p-0-0-2. Metatarsus I p1di, r0, v2-0-2; II p1-0-1, r1di, v2-0-2; III d1p-0-0, p1-0-2, r1-0-2, v2-0-2; IV p1-1-2, r1-1-2, v1p-0-2.

Color in alcohol ( Figs 18 A–B): carapace with triangle of scales pointing backward; areas beside triangle with less concentrated setae; abdomen ventrally pale, with three dark longitudinal stripes; lateral stripes with pale circles; legs: femur I with dark distal ring and dark prolateral stripe, II with dark distal ring and proximal region with incomplete dark ring (dorsally region not totally colored), III with dark distal ring and proximal region with dark prolateral spot, IV with dark distal ring and proximal region with dark ventral spot; tibia I–II with dark proximal ring and distal region with incomplete dark ring (dorsally region not totally colored), III–IV with distal and proximal dark ring; tarsus I–IV with dark proximal ring.

Epigyne ( Figs 18 C–D, 19A–D): copulatory openings separated by approximately twice the girth of copulatory ducts and placed anteriorly to primary spermathecae; copulatory ducts long; proximal copulatory duct approximately seven times longer than distal section; primary spermathecae elliptical and anteriorly projected.

Male. Unknown.
