HUBER, BERNHARD A., 2000, New World Pholcid Spiders (Araneae: Pholcidae): A Revision At Generic Level, Bulletin of the American Museum of Natural History 2000 (254), pp. 1-348 : 121-124

Papiamenta savonet , new species Figures 460 467

Pholcophora levii Gertsch, 1982: 99 100 (part of the records only).

TYPES: Male holotype, 2♀ paratypes from 3 km N Savonet , Curaçao, Netherlands Antilles ; stones, Dec. 28, 1962 (H. & L. Levi), in MCZ .

ETYMOLOGY: Named for the town close to the type locality. The specific name is a noun in apposition.

DIAGNOSIS: Closely related to P. levii , distinguished by the proximally much thicker male cheliceral apophyses (compare fig. 468 with 470; 461 with 469), and the bulbal apophyses (compare figs. 467, 473); the females are apparently not distinguishable.

MALE (holotype): Total length 2.0, carapace width 0.85, leg 1: 4.4 (1.16+0.32 +1.13+1.26+0.52), tibia 2: 0.94, tibia 3: 0.90, tibia 4: 1.35; tibia 1 l/d: 9. Habitus as in fig. 460. Entire prosoma orange-ochre, carapace with shallow but distinct thoracic groove (fig. 462), eight eyes on hardly elevated ocular area (figs. 460 461); distance PME-ALE about 50% of PME diameter. Sternum pale ochre, without anterior humps. Chelicerae with relatively huge cheliceral apophyses (figs. 462 463, 468), with stridulatory files (fig. 468; pick is a modified hair proximally on femur). Palps as in figs. 464 465, coxa without retrolateral apophysis, femur cylindrical, only slightly widened distally; tibia almost globular; procursus extremely simple, almost nonexistent (figs. 464, 466); bulb complex, consisting of globular part and two apophyses, one of them (a) movable, the other one (b+c) bifid (figs. 464 465, 467). Legs without spines and curved hairs, with some very short vertical hairs on tibiae; retrolateral trichoboth-

rium of tibia 1 at 66%; tarsus 1 with ~ 5–6 pseudosegments.

FEMALE (paratypes): Total length 2.3; tibia 1: 1.13, 1.19; without vertical hairs on tibiae. Epigynum apparently indistinguishable from P. levii (cf. figs. 476–477).

DISTRIBUTION: Known only from type locality (see Remark under P. levii ).

MATERIAL EXAMINED: NETHERLANDS ANTILLES: Curaçao: 3 km N Savonet: types above.

Figures 3 , 142 , 154 , 469–477 Pholcophora levii Gertsch, 1982: 99–100 (part; see P. savonet , above), figs. 12–13, 22–24.

TYPES: Male holotype and female from Piscadera Baai, Curaçao, Netherlands Antilles ; ‘‘dump,’’ Dec. 20, 1962 (H. W. Levi), in MCZ (examined) .

DIAGNOSIS: Closely related to P. savonet , distinguished by the more slender male cheliceral apophyses (compare fig. 468 with 470; fig. 461 with 469), and the bulbal apophyses (compare figs. 467, 473); the females are apparently not distinguishable.

MALE (holotype; see also Gertsch, 1982): Carapace width 0.79; tibia 1: 1.07. Habitus and prosoma shape as in P. savonet (cf. figs. 460–463); distance PME-ALE about 40% of PME diameter. Chelicerae with long frontal apophyses and stridulatory files laterally (fig. 470; pick is a modified hair proximally on femur, not on trochanter as noted in Gertsch, 1982). Palps in general as in P. savonet (cf. figs. 464–465); procursus extremely simple, almost nonexistent (figs. 471, 475) [note that Gertsch’s (1982) fig. 14 is misleading, as it shows one of the bulbal apophyses as if it were the procursus]; bulb complex, consisting of globular part and three apophyses, one of them (‘‘a’’) easily movable, describing half circle around other apophyses (figs. 471–474). Sternum without anterior humps.

Legs without spines and curved hairs, with some vertical hairs on tibiae 1 and 2.

Measurements of another male: total length 1.6, carapace width 0.80; leg 1: 4.17 (1.20+0.22+1.12+1.24+0.39), tibia 2: 0.97, tibia 3: 0.93, tibia 4: 1.31; tibia 1 l/d: 10; retrolateral trichobothrium of tibia 1 at 60%; tarsus 1 with ~ 6 pseudosegments.

FEMALE: Total length (N = 10) 1.9–2.5 (x¯ = 2.2); tibia 1 (N = 10) 1.06–1.19 (x¯ = 1.12); without vertical hairs on tibiae. Epigynum extremely simple, as in fig. 476, internally as in fig. 477; I could not see pore plates.

DISTRIBUTION: Known only from Curaçao ( Netherlands Antilles).

MATERIAL EXAMINED: NETHERLANDS ANTILLES: Curaçao: Piscadera Baai: types above ; SE airport, Dec. 20, 1962 (H. & L. Levi & B. de Jong), 13 10♀ in MCZ ; S slope Veeris Berg , Dec. 20, 1962 (H. Levi), 13 19♀ in MCZ ; Coral Specht , 3 km E Willemstad, Feb. 9–15, 1987 (W. E. Steiner & J. M.

Swearingen), ‘‘mesquite-acacia desert scrub near coast,’’ 3 3 1♀ 1 juvenile in USNM.

REMARK: The MCZ has two more vials, from ‘‘Grote Berg’’ and ‘‘Sint-Nicolaas, St.

Martha Baai’’ (see data in Gertsch, 1982), and the USNM has one more vial from Boca San Pedro, Feb. 10, 1987 (W. E. Steiner & J. M. Swearingen); however, these contain only females, and since females of the present species and P. savonet are apparently indistinguishable, they cannot unambiguously be assigned to any of the two species.
