Carapace: densely covered with rounded granules especially on the brown areas; lateral margins converging anteriorly; anterior margin very slightly bi-concave, without anteromedian projection ( Fig. 38 View FIGURES 36–39 ); ocular carinae strong and granulose, others inconspicuous; with a median depression anterior to the ocular tubercle; postocular furrow evident; median ocular tubercle low, located on the posterior half of the anterior third of carapace; lateral ocular tubercles each with four ocelli, being the posteriormost very reduced and unaligned with the remaining three pairs.

Chelicerae: with abundant fine white setae on the internal and ventral surfaces; cheliceral dentition characteristic of the family Buthidae ( Vachon 1963) . Movable finger dorsally with two small basal teeth, one median pronounced, one subdistal slightly shorter than the median, and one distal tooth. Ventrally with three strong teeth, one basal, one median, and one distal tooth larger than its dorsal counterpart. Fixed finger dorsally with one basal and one median tooth forming a bicuspid, one subdistal, and one distal tooth. Ventrally with only one subdistal tooth slightly basal to the dorsal subdistal.

Coxosternal region: sternum subtriangular, with deep median depression and two anterolateral furrows; all the components of this region with few setae, almost completely smooth except for few granulations on the anterior margin of coxae; coxapophyses I–II densely setose anteriorly.

Genital operculum and pectines: genital operculum completely divided longitudinally; pectinal basal piece as long as wide, deeply notched anteriorly; pectines long, with distal tip of marginal lamella reaching posterior end of coxae IV; count of pieces on the pectines: marginal lamellae 3:3, middle lamellae 8:9, teeth 21:21, fulcra absent.

Sternites: III completely smooth, lateral margins of IV–VI and posterior margin of VI with few granulations, VII densely granulose and with incomplete but strong paramedian longitudinal carinae, lateral carinae absent; V with subtriangular posterior median smooth area; spiracles elongated, approximately twice longer than wide in sternites III–IV and three times longer than wide in V–VI.

Tergites: with similar granulation to that of carapace; axial carina only evident on the posterior half of tergites I–VI; dorsolateral carinae absent on tergites I–VI; tergite VII tetracarinate, with incomplete paired dorsolateral and lateral carinae, and granulose median elevation on the position of the axial carina.

Metasoma: with few setae; segments I–III with ten carinae (paired ventrosubmedian, ventrolateral, median lateral, dorsolateral and dorsosubmedian carinae); segment IV with eight (median lateral carinae absent); segment V with five (ventromedian, paired ventrolateral and dorsolateral carinae); ventrolateral and median lateral carinae converge distally on segments I–II; ventrosubmedian and ventrolateral carinae are connected anteriorly by a transverse row of granules on segments II–IV; median lateral carinae on segment III obsolete; all carinae serrulate; dorsosubmedian carinae on segments II–IV with the distal granules well-defined and larger than the preceding; intercarinal spaces with minute dispersed granulation.

Telson: vesicle densely granulose laterally and (primarily) ventrally, with three ventral longitudinal carinae armed with strong granulation, and one noticeably larger granule (tubercle-like) under the subaculear tubercle; subaculear tubercle strong and spine-like; aculeus long and curved.

Pedipalps: with fine granulation on dorsal and internal surfaces of femur; femur with five longitudinal carinae (dorsoexternal, dorsointernal, ventroexternal, ventrointernal and internal median carinae); patella without distinct carinae but with few spine-like tubercles on the position of the dorsointernal and ventrointernal carinae; chela acarinate; fixed finger with six almost linear rows of granules, being the basal the longest; movable finger with seven rows (including the short apical row). Trichobothriotaxy type A, femur with β configuration ( Vachon 1974, 1975).

Legs: tibia, basitarsus and telotarsus with numerous ventral setae; tibial spur present on legs III–IV; prolateral pedal spur single on legs I–II, bifid on legs III–IV; retrolateral pedal spur present on all legs.

Hemispermatophore: Description based on one specimen from ICN-As-815: Flagelliform, thin and sclerotized. Foot narrow and flat. Pedal flexure inconspicuous but movable. Body long, slightly wider on basal third. Capsular region with a large, markedly sclerotized basal lobe, and an internal lobe. Flagellum with long pars recta and long, coiled pars reflexa ( Fig. 66 View FIGURES 64–67 ). Carapace length to hemispermatophore body length ratio = 1:1.28. There was no variation between both hemispermatophores examined.

Allotype female. Measurements: see Table 2. Figs. 26–27 View FIGURES 24–27 . Similar to holotype male but with the following differences deemed to be due to sexual dimorphism: body size larger; posterior median hyaline and smooth area of sternite V smaller and less evident; pectines markedly smaller, not reaching posterior end of coxae IV; telson not elongated. Aside from these primarily sexual differences, others include: general coloration darker; coxosternal region with minute brownish spots restricted to anterior half of coxapophyses I and anterior tip of coxapophyses II; anterior margin of coxae without any granulations; count of pieces on the pectines: marginal lamellae 3:3, middle lamellae 8:10, teeth 22:23, vestigial fulcra present; sternite IV with the same inconspicuous brownish areas that are found on V–VI.

Variability. Pectinal teeth count: 22 to 23 on females (n = 6; mode = 22); 20 to 23 on males (n = 16; mode = 21). Total body length (including telson): male 29–32 mm, female 41–43 mm.

Distribution. Known only from the type locality in Barbacoas municipality (Nariño Department), extreme southwestern Colombia in the western slope of the Andes ( Figs. 1 View FIGURE 1 , 56–57 View FIGURES 56–57 ).

Ecological notes. All specimens of A. ochoai sp. nov. were hand-captured at night after detection with UV light. Some individuals were detected when actively moving in the leaf litter, whereas others were found under decomposing logs. Ananteris ochoai sp. nov. was found in sympatry with A. dorae , Tityus sp. and Teuthraustes sp.
