Gertschiola neuquena View in CoL , new species Figures 351 View Figs 356

TYPE: Male holotype from Confluencia , Neuquén, Argentina ; Feb. 1976 (O. de Ferrariis), in AMNH .

ETYMOLOGY: The species name is an adjective, derived from the Argentinean state Neuquén.

DIAGNOSIS: Distinguished from G. macrostyla by the narrower procursus (compare figs. 346, 353), and the much longer tubular structure in the female internal genitalia (compare figs. 349, 354).

MALE (holotype): Total length 2.0, carapace width 0.9; leg 1: 8.9 (2.3+0.3+ 2.6+2.9+0.8), tibia 2: 2.2, tibia 3: 1.8, tibia 4: 2.3; tibia 1 l/d: 28. Habitus as in G. macrostyla (cf. fig. 342); entire prosoma ochre, only carapace with darker median line; thoracic groove very shallow, eight eyes on slightly elevated ocular area; distance PME- ALE about 35% of PME diameter. Sternum without humps. Chelicerae with frontal humps that are set with modified hairs (figs. 351 352), with stridulatory ridges laterally. Palps ochre to light brown, coxa without re- trolateral apophysis, femur proximally with stridulatory pick (modified hair) on prolateral side, inconspicuous apophysis on retrolateral side, tibia enlarged, procursus simple but long, ribbon-shaped (fig. 353), bulb with distinctive hooked apophysis and larger membranous embolar division (fig. 353). Legs ochre-yellow, no rings visible; without spines, but with some slightly curved hairs on metatarsi 1 and 2, and some vertical hairs on tibiae and metatarsi; retrolateral trichobothrium of tibia 1 at 73%; tarsus 1 with ~ 9 pseudosegments (difficult to see). Opisthosoma globular (rather as illustrated for Ibo- typoranga naideae , cf. fig. 357), greenishochre, covered with many darker spots, except ventrally.

FEMALE (Planicie Banderita): Very similar to male, but without curved hairs on legs. Carapace width 0.9; tibia 1: 1.9. Epigynum as in fig. 356; internal genitalia with long tubular structure (figs. 354 355).

VARIATION: Measurements of male from Planicie Banderita: carapace width 1.0; tibia 1: 3.5. Tibia 1 in the females from Loma de la Lata: 1.9, 2.1.

DISTRIBUTION: Known only from Neuquén, Argentina.

MATERIAL EXAMINED: ARGENTINA: Neuquén: Confluencia: type above. Planicie Banderita: Feb. 1, 1976 (Coscarón), 13 1♀ in AMNH. Loma de la Lata, Jan. 1, 1973 (O. de Ferrariis), 2♀ 1 juvenile in AMNH. Loma de la Lata, Confluencia, Nov. 26, 1972 (O. de Ferrariis), 1 penultimate male in AMNH.
