Description.
MALE:
Measurements
(
n
=3) DSW: 4.0-4.2 (4.2); DSL: 3.6-4.3 (4.1); CL: 1.5-2.0 (2.0). FIVL: 6.6-7.3 (7.3). ChL: 1.2-3.6 (3.2).
Coloration
: (Fig.
24A
) Reddish carapace with blackish sides. Dorsal scutum and free tergites brownish orange. Lateral margins of DS, small tubercles on scutal areas, spines on area III and free tergites yellow. A dry-mark on depression of ocularium, carapace, and lateral region to ocularium.
Pedipalpus
and chelicerae yellow with small black spots. Legs I-II with coloration similar to dorsal scutum. Legs III-IV reddish brown.
Dorsum
: (Fig.
4A
) Row of granules on the anterior margin of dorsal scutum and the median elevation. Granules more concentrated on carapace sides and on posterior region to ocularium. Ocularium with a relative strong depr ession; with pair of small tubercles and few granules near the eyes. Dorsal scutum with scutal grooves almost inconspicuous; grooves I and II more visible than others; granules sparsely distributed throughout scutal areas. Areas I-IV with a lateral pair of tubercles; I with a pair of median tubercles, larger than those on the lateral portion of scutal areas; III with a pair of large median blunt spines, base with small tubercles. Lateral margins of DS sparsely covered with granules throughout extension. Posterior margin of DS and free tergites I-III each one with a median pair of tubercles and a row of few granules.
Chelicerae
: (Fig.
4A
) Swollen in large males, similar to females in the small males. Segment I with three small prolateral tubercles and one large tubercle located medially or retrolaterally. Segment II with small setiferous granules, concentrated more distally; one tooth. Segment III with two teeth.
Pedipalpus
: Trochanter with a ventroapical setiferous tubercle. Femur with a ventral row of 6-7 setiferous tubercles of irregular size, the largest being the most apical; one proapical spine. Patella with a promedian spine. Tibia: retrolateral iiIIIi, prolateral IIII. Tarsus: retrolateral iIiIi, prolateral iIIi.
Venter
: Coxa I with a median row of 5-6 setiferous tubercles, the most median of which is larger; III-IV with small granules sparsely distributed. Rows of tubercles between the coxae II-III and III-IV. Genital area, anal operculum and free sternites with few granules.
Legs
: (Figs
4A
,
11A, B
) Coxa I-II each one with a prolateral and a retrolateral apophysis. Coxa III unarmed. Coxa IV with setiferous granules distributed throughout its surface, with the largest clustered apically. Trochanters I-IV unarmed and with a few granules. Femora I-III unarmed and with few granules. Femur IV unarmed and with more abundant and larger granulation than those of the other femora. Patellae-tibiae I-IV unarmed with few granules. Tarsal segmentation: (
n
=3) 7-8 (7), 16-17 (17), 15-17 (17), 16-17 (17).
Penis
: (18A-C) VP rectangular, with distal margin straight; VP wide and robust in lateral view. MS C1-C13(C14) subapical long and apically curved; MS A1 median short and straight; MS B1-B2 median-basal long and straight (longer than MS A, shorter than MS C); MS D1 very short, placed dorsally, near MS C. Lateral sacs very short (twice as long as wide), apically blunt, with short T3-like microsetae. Stylus with apex dorsoventrally expanded and with apical projections. Dorsal process absent. Promontory convex. -

24B
) Chelicerae small, not swollen. Femur IV with less dense granulation, with granules smaller than those of males. Tarsal segmentation: (
