( Figs. 1–13 , Table 1 )

Ananteris sp.: Botero-Trujillo (2006)

Type material. Female holotype from Colombia, department of Meta, Villavicencio, Path El Carmen, 850– 1000m, into forest, Pitfall, December 23/2005, M. Viola (MPUJ-SCO-245). One female paratype from Colombia, department of Meta, Villavicencio, Path El Carmen, 850–1000m, River Caño Blanco, under litter, ad hoc, at night, April 18/2005, R. Botero-Trujillo (MPUJ-SCO-039).

Etymology. Patronym dedicated to the author’s mother, Myriam Trujillo, in recognition to her great human quality and acknowledgement to her support and encouragement.

Diagnosis. Species of moderate size with predominantly brown coloration; anterior margin of the carapace with two concavities ( Fig. 6 ); female pectines with 15–16 teeth; carinal formula of metasoma 10:10:10:6:5; metasomal carinae without spinoid granules. The new species may be easily distinguished from all other known Colombian Ananteris by the non-straight anterior margin of the carapace, the carinal formula of metasoma, and that v1 and v2 trichobothria are not aligned axially ( Fig. 13 ). On the contrary, in the other four species the anterior margin of the carapace is straight, carinal formula is 10:10:8:8:5, and v1 and v2 are aligned axially.

Description based on female holotype (MPUJ-SCO-245):

Morphometric measurements in Table 1 .

Coloration. General coloration yellowish brown with variegated pigmentation over the entire body and appendages. Prosoma: carapace predominantly brown with some yellow spots and bands; anterior and posterior margins brown; arising posterior to the lateral eyes there are two thin and almost straight yellow lines each directed toward the midline, but do not reach it; median ocular tubercle blackish, surrounded on its base by thin yellow lines in the anterior, anterolateral and posterolateral margins. Chelicerae: coxa, tibia and tarsus yellowish; tibia with a complete reticular pattern in dorsal view, anterior section brown; fixed finger yellow with reddish teeth; movable finger with a dorsal brown area at the base ( Fig. 3 ), teeth reddish. Coxosternal region: general coloration yellowish; sternum and coxapophyses II yellow; coxae I–IV and coxapophyses I with diffuse brown spots ( Fig. 4 ). Tergites: predominantly brown; two longitudinal yellow lines crossing from tergites I to VII are only evident in the posterior half of each segment near midline; these lines are more conspicuous in tergites III–VI and appear as rounded spots in tergites I–II; each side of tergites II–VI with two transverse yellow lines converging near to the longitudinal lines, resembling an arrow; tergite VII with variegated pigmentation; lateral margins of tergites I–VII yellowish, with one anterior brown area. Ven te r: general coloration yellowish; genital operculum yellow; middle basal piece with inconspicuous dark spots; basal lamellae of the pectines with inconspicuous brown spots at the base ( Fig. 4 ); sternite I with two brown-spotted areas in the anterior margin, close to the midline and hidden under the pectines; sternites II–IV with brown spots in the posterior margin, located midway between the booklung spiracles and the midline; these spots are greater in size in sternite V; sternites I and III with a posterior median hyaline area, greater in size in sternite I ( Fig. 5 ). Metasoma: general coloration yellowish brown; dorsal intercarinal space of segments I–IV with a median brown design that is wider in the anterior portion, resembling a triangle in segments I–III; all intercarinal spaces of segments I–IV with variegated pigmentation, except for those between d and dl carinae that are predominantly yellow; d and dl carinae of segments I–III brownish; segment V reddish, darker in the posterior portion in ventral and lateral views; telson reddish, lightly than segment V and with a lateral yellowish band directed longitudinally on each side; aculeus dark-red over almost its entire length and yellowish at the base; subaculeus yellowish. Pedipalps: coxa and trochanter with variegated pigmentation; femur brown in dorsal and internal surfaces, ventral face yellowish, external face with a longitudinal yellow band, insertion of all the trichobothria yellow; patella brownish with variegated pigmentation in dorsal, internal and external surfaces, ventral face yellowish, insertion of the trichobothria yellow, two yellowish bands arise dorsally and externally from the base and end near the half of the segment; hand completely yellow, fixed and movable fingers palebrown colored with the tip yellowish. Legs: with variegated pigmentation, yellow spots in all segments, telotarsus predominantly yellow.

Morphology. Prosoma: carapace with intense granulation, denser in the brown-colored areas; anterior margin with two concavities ( Fig. 6 ); all carinae inconspicuous; a median depression anterior to the ocular tubercle and a posterior median longitudinal furrow are evident; median ocular tubercle in the posterior portion of the carapace most anterior third; three pairs of lateral eyes. Chelicerae: with numerous hairs in the internal and ventral surfaces; cheliceral dentition characteristic of the family Buthidae ( Vachon 1963) . Coxosternal region: sternum pentagonal with a median depression producing two anterolateral furrows ( Fig. 4 ); all the components of this region smooth; coxapophyses I–II with anterior dense pilosity. Tergites: all tergites with intense granulation, denser in the brown-colored areas; median longitudinal carina only evident in the posterior half of tergites II–VI, and absent in tergites I and VII; tergite VII tetracarinate with only a slight dorsal convexity replacing median carina. Ve nt er: genital operculum divided longitudinally; pieces count on the pectines: basal lamellae 3:3, middle lamellae 8:7, teeth 15:15; fulcra absent; teeth increase in length distally; basal piece of the middle lamellae not dilated; middle basal piece heart-shaped ( Fig. 4 ). Sternites with very thin granulation, denser in sternite V; sternites I and III with a posterior median smooth area; sternite V with two vestigial longitudinal carinae represented by some isolated granules; booklung spiracles oval elongate ( Fig. 5 ). Metasoma: segments I–III with ten carinae (paired vm, vl, l, dl and d carinae), segment IV with six carinae (l and vm absent), segment V with five carinae (l and d absent, single vm); all carinae serrulate; intercarinal spaces with granulations; l and vl carinae converge distally in segments I–III. Telson very elongated, with the vesicle dorsal surface almost straight and the ventral surface with a slight convexity in lateral view; vesicle with three vestigial longitudinal carinae (single vm and paired vl) that are represented by some granules; dl carinae are only evident proximally; vm carina gives origin to an arrow-shaped subaculeus and a preceding well developed granule. Aculeus long and curled ( Fig. 7 ). Pedipalps: femur pentacarinate; patella without distinct carinae, but armed with spine-like granules in the internal surface; tibia without distinct carinae; fixed finger with six almost linear rows of granules, the basal the longest, each one with the three more basal teeth greater in size—except for the longest row whose granules are all equally sized; movable finger with seven rows, the same greater granules are present; trichobothriotaxy type A, femur with β configuration ( Vachon 1974, 1975) ( Figs. 8–13 ). Legs: tibia, basitarsus and telotarsus with numerous ventral setae; tibial spur present in legs III–IV; prolateral pedal spur single in legs I–II, bifid in legs III–IV; retrolateral pedal spur present in all the legs.
