Diagnosis

(amended from Bertani and Fukushima 2009). Females of Ybyrapora sooretama comb. n. resemble those of Ybyrapora gamba comb. n. by elongated spermathecae with accentuated outwards curvature medially and by retaining vestiges of characteristic juvenile color pattern on abdomen. They differ from those of Ybyrapora gamba comb. n. by spermathecae bearing multilobular apex (Fig. 257). Males resemble those of Ybyrapora gamba comb. n. by embolus length 3.0 to 3.5 times tegulum’s length and lacking a very strong curvature in frontal view (Fig. 262). They differ from those of Ybyrapora gamba comb. n. by developed prominence on tegulum (Fig. 262) and by central longitudinal black stripe on dorsal abdomen.

Complementary description.

Male: Palp (Figs 260-263): globous bulb with small subtegulum and developed prominence on tegulum. Embolus: not flattened, lacking keels, 3.15 long in retrolateral view, about 3.5 times tegulum’s length. Medial portion and tegulum’s margin form an obtuse angle in retrolateral view. Proximal part very curved in frontal view; thin distal width, abruptly narrowing distally; basal, middle, and distal width of 0.63, 0.13, 0.03, respectively. Tegulum: 1.61 long, 0.94 high. Cymbium subtriangular with subequal lobes, lacking process on retrolateral lobe (Fig. 264).

Tibial apophysis in leg I absent (Figs 265-267).

Type II urticating setae: 0.633-0.681 long; 0.012-0.016 wide in male; 0.422-0.490 long; 0.009-0.012 wide in female.

Female: Spermathecae (Fig. 257): two completely separated, not-twisted, long spermathecae, with multilobular apex and accentuated outwards curvature medially. Spermatheca midwidth as wide as its base width, virtually non-sclerotized.
