Grismado, Cristian J. & Carrión, Nicolás López, 2017, Description of Almafuerte, a new genus of ground spiders from South America (Araneae, Gnaphosidae), Zootaxa 4338 (2), pp. 263-291 : 285

Almafuerte facon sp. nov.

( Figs. 19 a–e ; 20 e–f; 22b)

Type. Holotype male from Bolivia: Cochabamba Department, 10 km. Sacaba , elev. 3300 m, 28–29.I.1976, without collector (MACN-Ar 18154, prep. CJG 1518).

Etymology. The “ facón ” is a knife (used as tool and as weapon) by the gauchos. The specific epithet refers to the straight and acute shape of the ventral branch of the RTA in retrolateral view.

Diagnosis. The male of A. facon is similar in the RTA, and the general shape of the bulb to that of A. goloboffi , but the ventral protrusion of the ventral part of tegulum is less pronounced. Other differences from A. goloboffi are the more straight ventral branch of the RTA (in retrolateral view), and the absence of a distal ventral retrolateral ledge on the palpal patella ( Fig. 20 f ).

Description. Male holotype: Measurements: Total length 8.22, carapace 4.02 long, 3.08 wide; sternum 2.11 long, 1.64 wide.

Leg spination: femora: I d1-1, p0-0-0/1-1; II d1-1-0, pd 0-1-1; III d1-1, pd 1-1-0-0/1, rd 0-1-1; IV d1-1, p1, r0-0-1-1; patellae: III r1, IV r1; tibiae: I p0-0-1, v2-2 -2ap, II p1-1-1(right), 1-0-1-1 (left), v2-2 -2ap III d1-0-0, p1-0-1-1, v2-2 -2ap, r1-1; IV p1-0-1 (right) 1-1-1 (left, not paired), v2-2 -0-2ap, r1-1-0-1(right) 1-1 (left); metatarsi I p0-1-1, v2-2, r0-0-1; II p0-1-1, v2-2, r0-0-1; III d2-2-2, p0-1-1, v2-2 -2ap, r0-1-1; IV d2-2-2, p0-1-1, v2-2 -2ap, r0- 1-1. Palp ( Figs. 19 c–e ; 20 e–f): similar to that A. goloboffi except by the differences above described. All other characters are common for the genus.

Natural history and habitat preferences. Unknown.

Material examined. Only the holotype.

Distribution. Only known from the type locality, in Cochabamba, Bolivia.
