Name
Ybyrapora gamba (Bertani & Fukushima, 2009) comb. n. – Wikispecies link – Pensoft Profile
Diagnosis
(amended from Bertani and Fukushima 2009[1]). Females of Ybyrapora gamba comb. n. resemble those of Ybyrapora sooretama comb. n. by elongated spermathecae with accentuated outwards curvature medially (Fig. 258) and by retaining vestiges of the characteristic juvenile color pattern on abdomen (Fig. 298). They differ from those of Ybyrapora sooretama comb. n. by spermathecae lacking multilobular apex (Fig. 258). Males resemble those of Ybyrapora sooretama comb. n. by embolus length 3.0 to 3.5 times tegulum’s length (Fig. 269) and by lacking strong curvature in frontal view (Fig. 270). They differ from those of Ybyrapora sooretama comb. n. by lacking prominence on tegulum (Fig. 270) and by having central longitudinal red stripe on dorsal abdomen (Fig. 297).

Complementary description
Male: Palp (Figs 268–271): globous bulb with small subtegulum lacking prominence on tegulum. Embolus: not flattened, lacking keels, 2.34 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 slightly curved in frontal view; thin distal width, tapering distally; basal, middle, and distal width of 0.44, 0.11, 0.03, respectively. Tegulum: 1.03 long, 0.59 high. Cymbium subtriangular with subequal lobes, lacking process on retrolateral lobe (Fig. 272).
Tibial apophysis in leg I absent (Figs 273–275).
Type II urticating setae: 0.605–0.750 long; 0.012–0.017 wide in male; 0.301–0.352 long; 0.006–0.009 wide in female (ecdise).
Female: Spermathecae (Fig. 258): two completely separated, not-twisted long spermathecae lacking lobes and accentuated outwards curvature medially. Spermatheca midwidth as wide as its base width, virtually not sclerotized.
