Aglaoctenus puyen View in CoL sp. nov.

( Figs 5–6 View FIGURE 5 View FIGURE 6 , 18 View FIGURE 18 a, 19a, 20)

Type material. Female holotype from Argentina: Neuquén: San Martín de los Andes, Cerro Chapelco (ca. S 40.223611° W 71.288889° -+ 2140 m), II.1961, Galiano, M. E. (MACN-Ar 5319; temporary preparation LNP- 00044) and female paratype with the same data (MACN-Ar 20301).

Other material examined. ARGENTINA: Río Negro: Cerro Catedral, Laguna Toncek (ca. S 41.199722° W 71.485833° -+ 2085 m), 13.I.1964, 1 female (MACN-Ar 24099; temporary preparations LNP-00041 and LNP- 00608).

Diagnosis. Females of A. puyen sp. nov. can be distinguished from other species of Aglaoctenus by the wide marginal light brown bands in the carapace ( Fig. 5 View FIGURE 5 a), and by the epigyne that has a wide longitudinal septum, similar to A. oblongus ( Fig. 13 View FIGURE 13 a) but without well developed lateral projections ( Fig. 6 View FIGURE 6 a).

Description. Female (holotype). Colour in ethanol ( Fig. 5 View FIGURE 5 , 19 View FIGURE 19 a): carapace reddish-brown, covered by dark setae; wide, light brown marginal bands, enhanced by white setae. Chelicerae, endites and labium dark brown. Sternum and coxae brown, femora brown with light areas; patellae, tibiae, metatarsi and tarsi brown. Scopulae dense from distal ventral half of tibiae trough tarsi. Abdomen dorsally reddish-brown, with two pairs of anterior white spots, followed by a third pair of spots united by a line of white setae; ventrally light brown. Epigyne (female MACN-Ar 24099 dissected) ( Fig. 6 View FIGURE 6 a), median septum wide, without lateral projections, covered by plumose setae. Internal genitalia, ( Figs 6 View FIGURE 6 b, 18a) spermatheca with long and twisted stalk, head of spermatheca with small projections, vulval chamber semi-oval. Fertilization ducts small and membranous, connected to the base of spermatheca at its posterior side.

Anterior eye row slightly procurved, ALE in small tubercles ( Fig. 19 View FIGURE 19 a). Chelicerae: 4.67 length, three promarginal teeth, the median largest; retromargin with three equal equidistant teeth. Abdomen: length 9.98, width 6.92.
