Color
. Color is brown, lighter on the legs. Faint underlying mottling on the carapace and mesosoma.
Carapace (
Fig. 4
).
Anterior margin of carapace moderately emarginated, posterior margin slightly emarginated. Carapace finely granular. Three lateral eyes on each side. Median furrow moderate and traverses entire length of carapace. Ratio of median eyes location from anterior edge/carapace length 0.69; carapace length/ width at median eyes 1.43. Carapace of female is longer than metasomal segment V.
Mesosoma (
Fig. 9
).
Tergites finely granular with vestigial median carina on Tergites I-VI. Tergite VII with weak median carina on anterior third and strong dorsal lateral and lateral supramedian granular carinae. Sternites III-VI finely granular and without carinae. Sternite VII with granular ventral lateral carinae on middle third. Presternites smooth. Spiracles ovoid with median side rotated 35º from posterior sternite margin. Sternites with variable number of microsetae.

Ventral view.
Upper Right.
Closeup of median area, internoventral and ventral views.
Bottom.
Mating plug, dorsal and ventral views, showing smooth barb (in dorsal view). Note in all ventral views of the hemispermatophore the embedded matinig plug is visible, the barb positioned towards the internal edge. Due to the translucency of the lamina, the ventral trough edge is visible from the dorsal view and the bifurcated lamellar hook, which emanates from the dorsal trough edge, is visible from the ventral view.
Sternum.
Sternum is
type
2 (Soleglad & Fet, 2003) and is wider than long.
Genital Operculum.
Sclerites separated on posterior one-fifth.
Pectines.
Pectinal tooth count for the
holotype
female 10/10 and 14/15 for the
paratype
male. All pectinal teeth have exterodistal angling with large sensorial area. Middle lamellae 6/6. Fulcra are present. Each fulcrum with one central seta.
Metasoma (
Fig. 8
).
Carapace of female is longer than the fifth metasomal segment. Ratio of segment I length/ width 0.74;.of segment II length/width 0.97; of segment III length/width 0.99; of segment IV length/ width 1.34; of segment V length/width 2.05. Segments I-IV: dorsolateral carinae moderate, granular. Lateral supramedian carinae I-IV strong and granular with enlarged spinoid distal denticle on I & II. Lateral inframedian carinae moderately granular on segment I, posterior 3/5 of II, 2/5 of III, and obsolete on IV. Ventrolateral carinae I weak and granular; on II-III moderate, granular; on IV strong, granular. Ventral submedian carinae weak to moderate on segment I, moderate on II, moderate, granular on III and moderate to strong, granular on IV. Dorsal and lateral intercarinal spaces very finely granular. Segment I-IV ventral submedian setae 3/3. Segment V: Dorsolateral carinae weak, distally crenulate, basally granular Lateromedian carinae moderate, granular. Ventrolateral and ventromedian carinae moderate. Intercarinal spaces finely granular. Segment V ventrolateral setae 4/4.
Telson (
Fig. 7
).
Smooth with 4 pairs of large setae on the ventral surface, 3 large setae along both lateral edges of the vesicle and numerous smaller setae. Small, obsolete subaculear tubercle present.
Chelicerae (
Fig. 6
).
Dorsal edge of movable cheliceral finger with two subdistal (sd) denticles. Ventral edge is smooth, with well developed serrula on distal half.

) (see

and
it
located at base of fixed finger. Pedipalp ratios: chela length/width 3.88; femur length/width 3.39; patella length/width 3.14; fixed finger length/carapace length 0.72.
Chela (
Fig. 5
).
Carinae moderate. Fixed finger with median (
MD

denticles. Movable finger with 6 subrows, 5
OD
denticles and usually 7
ID
denticles (Soleglad & Sissom, 2001).
