Etymology. The specific epithet is a patronymic in honor to Dr. Irene Ester Gonzalez Garay, researcher at Universidade do Brasil /Universidade Federal do Rio de Janeiro ( UFRJ). She worked for a long time in the Tableland Forests of Sooretama   and Linhares, providing foremost contributions to the understanding of the composition of the litter fauna in the area.

Diagnosis. Males of this species are similar to O. arietina Simon, 1892   , O. janthinipes Simon, 1893   , O. fagei Brignoli, 1974   , O. hamadryas   , among others. All these and similar species bear an elongated apical cymbium apophysis, with a claw-like cuspule and a bulbus varying from ovoid to oblong, with a long embolus ( Figs. 6A View FIGURE 6 , 7A View FIGURE 7 , Simon 1892, fig. 10, Fage 1912, figs. 42, 80, 81, Brescovit et al. 2018, figs. 1C–D, 2C–E, 4C–D, 5C–F). Ochyrocera garayae   new species has a genitalic pattern more similar to O. vesiculifera   , as both species display a pretty similar cymbium, which gradually tapers towards an apophysis displaced to the retrolateral apical margin (not at the median line of the cymbium) ( Figs. 5C View FIGURE 5 , 7A View FIGURE 7 , Fage, 1912, fig. 81), and a large roundish bulbus, with a ribbon-like embolus ( Figs. 5 View FIGURE 5 B–C, 6A, 7A, Fage, 1912, figs. 80, 81). Ochyrocera garayae   new species can be set apart by the tip of the cymbial apophysis, which is clearly curved towards the median line of the cymbium, a perfectly ovoid tegulum ( Figs. 6A View FIGURE 6 , 7A View FIGURE 7 ) and a ribbon-shaped embolus, longer than the bulbus proper and with many little thorn-like projections at its dorsal face up to its apical fourth, where there is a strong constriction, and a curved and narrow tip ( Figs. 6A View FIGURE 6 , 7A, B, D View FIGURE 7 ).

On the other hand, females have a genitalia resembling those of O. tinocoi   new species, as both species have a vulva composed of tubular spermatheca with adjoining pore plates, a wide membranous sac (uterus externus?), forming an anterior flap ( Figs. 2C View FIGURE 2 ; 6C View FIGURE 6 ). Ochyrocera garayae   new species may be set apart by the wider and shallower uterus externus, bearing a bowl-like flap, much wider than long, and by the shorter and more rugose spermathecae, also with a larger tip ( Figs. 2C View FIGURE 2 ; 6C View FIGURE 6 ). Furthermore, males and females of O. garayae   new species have a unique light yellow background body colour (darker in male carapace) ( Fig. 5 View FIGURE 5 A–F).

Description. Male (Holotype MNRJ 06839): Measurements: Total length (prosoma + opisthosoma) 1.39. Carapace 0.5 long, 0.47 wide, 0.17 high. Abdomen 0.88 long, 0.41 wide, 0.43 high. Prosoma: carapace ovoid, yellow, with a median dark blue stripe and one dark blue lateral irregular stripe on each side, mixed with some yellowish spots ( Fig. 5 View FIGURE 5 A–B). Dark blue V-shaped area around fovea ( Fig. 5A View FIGURE 5 ) over the median stripe. Chelicera yellow bearing seven yellow subequal promarginal teeth between the translucent lamina and the somewhat reddish dagger-like fang ( Fig. 6B View FIGURE 6 ). Endites yellow ( Fig. 5C View FIGURE 5 ). Sternum yellowish with a series of small bluish spots near each coxa ( Fig. 5C View FIGURE 5 ). Eyes: Six eyes slightly elevated moderately divided in three dyads, with PME more elevated than the others, all ringed in black located in a dark blue area ( Fig. 5 View FIGURE 5 A–B). Legs: pale yellow with blue patches on the distal part of articles ( Fig. 5B View FIGURE 5 ). Leg I with three tarsal claws. Prolateral superior claw bears two rows of teeth, the medial row shorter only on apical third. Retrolateral superior claw with a single row of teeth ( Fig.7C View FIGURE 7 , partially hidden by prolateral superior claw). Opisthosoma ( Figs. 5 View FIGURE 5 A–C; 8A): longer than wide, cylindrical. Dorsum pale yellow with dark blue edge and eight patches and a terminal spot in the same colour ( Fig. 5A View FIGURE 5 ). Venter pale yellow with a bluish spot in front of spinnerets ( Fig. 5C View FIGURE 5 ). Epiandrous with five to seven fusules, with globular base linearly (recurved) arranged in a rugose depression anterior to epigastric furrow ( Fig. 8 View FIGURE 8 B–D). Anal tubercle wider than high with rounded setae ( Fig. 9E View FIGURE 9 ). Spinnerets ( Fig. 9 View FIGURE 9 ): colulus triangular, moderately developed, with few setae irregularly distributed ( Fig. 9A View FIGURE 9 ); ALS with one major ampullate gland spigot accompanied by a nubbin and six piriform spigots ( Fig. 9B View FIGURE 9 ); PMS with one minor ampullate spigot ( Fig. 9D View FIGURE 9 ); PLS has compactly packed row of 15 aciniform gland spigots with long bases ( Fig. 9C View FIGURE 9 ). Genitalia ( Figs. 6A View FIGURE 6 ; 7 View FIGURE 7 A–B, D–F): Palpal femur tubular ( Fig. 7A View FIGURE 7 ). Tibia tubular with a slightly incrassate base ( Fig. 7A View FIGURE 7 ). Cymbium thick and oval, bearing a pedestal on its basis, and ending in an elongated finger-like distal terminal apophysis, a little longer than the cymbium itself, and tipped by a short curved cuspule ( Figs. 6A View FIGURE 6 ; 7A, F View FIGURE 7 ). Tarsal organ elevated, striated, with two marginal cuticular lobes and one sensillum ( Fig. 7E View FIGURE 7 ). Tegulum globose with sperm ducts diameter tapering gradually from fundus to opening ( Fig. 6A View FIGURE 6 ). Embolus medium-sized, ribbon-shaped, with many little thorn-like projections at its dorsal face up to its apical fourth, where there is a strong constriction, and a curved and narrow tip ( Fig. 7B, D View FIGURE 7 ).

Female (Paratype MNRJ 06842): Measurements: Total length 1.39. Carapace 0.54 long, 0.46 wide, 0.18 high. Abdomen 0.85 long, 0.57 wide, 0.66 high. Colour pattern similar to male, but a little paler ( Fig. 5D View FIGURE 5 ). Endites bluish ( Fig. 5F View FIGURE 5 ). Sternum with two wide longitudinal dark blue lateral stripes ( Fig. 5F View FIGURE 5 ). Opisthosoma ( Fig. 5 View FIGURE 5 D–F): ovoid, slightly longer than wide. Venter with more dark blue pigment at the anterior portion, some scattered dark blue spots at median portion and a fading bluish spot before spinnerets ( Fig. 5F View FIGURE 5 ). Genitalia ( Fig. 6C View FIGURE 6 ): vulva with two tubular spermathecae enlarged and rounded at their apical end, with two rounded pore plates on its basis with just a few glandular pores. Membranous sac (uterus externus?) much wider than high and weakly sclerotized, extending anteriorly in a wide and bowl-like neck.

Natural History. Same as O. tinocoi   new species.

Distribution. Only known from Linhares and Sooretama   , both in northern Espírito Santo state, Southeastern Brazil ( Fig. 14A View FIGURE 14 ).
