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 : 251-255

Coryssocnemis guatopo , new species Figures 995 –1000

TYPE: Male holotype from 28 km N Altagracia, Guatopo Nat. Park , Dept. Miranda, Venezuela ; 700 m elev., ‘‘ El Lucero, ravine,’’ May 31–June 7, 1987 (S. & J. Peck), in AMNH .

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

DIAGNOSIS: Closely related to C. callaica ; easily distinguished by the epigynum (compare figs. 993–996). Distinguished from oth- er congeners by the sclerotized cones frontally on the male chelicerae in arches and the additional pair of pointed apophyses closer to the median line (fig. 997), and by the short apophyses on the bulb (figs. 998–999).

MALE (holotype): Total length 2.2, carapace width 1.0; leg 1 missing, tibia 2: 3.7, tibia 3: 2.7, tibia 4: 3.5. Habitus and prosoma shape as in C. simla (cf. figs. 980, 982–983); carapace brown, darker medially, ocular area dark brown; distance PME-ALE about 70% of PME diameter. Sternum ochre, darker anteriorly; chelicerae ochre and brown, with several cone-shaped sclerotized apophyses in lateral arches, pair of pointed apophyses medially, and pair of rounded, upward-facing apophyses distally (fig. 997). Palps in general as in C. simla (cf. figs. 984–985), procursus as in fig. 1000, bulb with several short apophyses and semitransparent projection (figs. 998–999). Legs light brown, femora with subdistal dark rings and light tips, tibiae with faint proximal and more distinct subdistal dark rings, and light tips; femora 2 not thicker than others; legs without spines, without curved and vertical hairs. Opisthosoma greenish-gray, dorsally covered with dark spots; genital plate wide, dark brown; black band behind genital plate halfway to spinnerets.

VARIATION: Three of the other four males examined had spines in two rows ventrally on femora 2. In two of these males, femora 2 were slightly thicker than the others. The fourth male lacked spines on both femora 1 and 2. Measurements of two other males: tibia 1: 8.8, 9.6; tibia 2: 5.6, 6.0; retrolateral trichobothrium on tibia 1 at 3.4%; tarsus 1 with ~ 30 pseudosegments (difficult to count).

FEMALE: Similar to male, but legs much thinner and shorter (tibia 1 in 2 females: 5.7, 6.4), without spines. Epigynum dark brown plate with shallow anterior indentation (fig. 995); internal genitalia with small pore plates (fig. 996).

DISTRIBUTION: Known only from Guatopo Nat. Park, Miranda, Venezuela.

MATERIAL EXAMINED: VENEZUELA: Miranda: Guatopo Nat. Park : type above ; Guatopo Nat. Park, Agua Blanca , 400 m elev., forest streamside, June 7–14, 1987 (S. & J. Peck), 13 in AMNH ; same locality, ravine, May 31–June 7, 1987 (S. & J. Peck), 13 in AMNH ; Guatopo Nat. Park, Santa Cruzita , 450 m elev., Feb. 14, 1984 (J. Coddington), 23 2♀ (2 vials) in USNM .

Coryssocnemis monagas , new species Figures 1001–1004

TYPE: Male holotype from 27 km SW Caripe , Monagas, Venezuela ; 300 m elev., ‘‘forest over coffee,’’ July 19–31, 1987 (S. & J. Peck), in AMNH .

ETYMOLOGY: Named for the Venezuelan state Monagas. The specific name is a noun in apposition.

DIAGNOSIS: Distinguished from congeners by the shape of the bulbal apophyses (figs. 1002–1003), and the armature of the male chelicerae, which are equipped with proximal humps and two pairs of distal apophyses, but lack sclerotized cones (fig. 1001).

MALE (holotype): Carapace width 1.3, opisthosoma missing; leg1: 26.8 (6.3+0.5+6.5 +11.5+2.0), tibia 2: 4.0, tibia 3: 3.2, tibia 4: 3.9; tibia 1 l/d: 65. Habitus and prosoma shape as in C. simla (cf. figs. 980, 982–983); entire prosoma light brown, only ocular area slightly darker; distance PME-ALE only ~ 45% of PME diameter. Chelicerae light brown, with blackish proximal hump, and two pairs of distal apophyses, one rather pointed, one round (fig. 1001). Palps in general as in C. simla (cf. figs. 984–985), procursus as in fig. 1004, embolar division with characteristic projections, one bifurcated and rather sclerotized, the other rather membranous (figs. 1002–1003). Legs light brown, femora with subdistal dark rings and light tips, tibiae with light tips; femora 2 not significantly thicker than others; femora 1–3 with spines ventrally (cf. fig. 981), on femora 3 spines almost look like ‘‘normal’’ hairs; all legs without curved and vertical hairs; retrolateral trichobothrium of tibia 1 at 4%; tarsus 1 with over 20 pseudosegments.

FEMALE: Unknown.

DISTRIBUTION: Known only from type locality.

Coryssocnemis aripo , new species Figures 1005–1013

TYPES: Male holotype, 2♀ paratypes from

El Cerro del Aripo (Mt. Aripo), ‘‘ Cave No. 1,’’ Trinidad ; 2200 ft elev., no date (P.C.J. Brunet), in AMNH .

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

DIAGNOSIS: Distinguished from congeners by the 2–3 sclerotized cones frontally on each male chelicera (fig. 1005), by the absence of upward-bent apophyses on the male chelicerae, and by the shape of the bulbal apophyses (figs. 1008–1009).

MALE (holotype): Total length 2.6, cara- pace width 1.3; leg 1: 40.3 (9.2+0.5+9.3 +17.7+3.6), tibia 2: 6.0, tibia 3: 4.7, tibia 4: 5.9; tibia 1 l/d: 78. Habitus and prosoma shape as in C. simla (cf. figs. 980, 982–983); carapace pale ochre with dark median stripe, ocular area slightly darker; distance PME- ALE about 90% of PME diameter. Sternum pale ochre-yellow; chelicerae light ochrebrown, with blackish cones frontally (fig. 1005). Palps in general as in C. simla (cf. figs. 984–985), femur as in fig. 1007, procursus and bulb as in figs. 1006, 1008–1009. Legs monochromous pale ochre-yellow; without spines, without curved and vertical hairs; retrolateral trichobothrium of tibia 1 at 3%; tarsus 1 with over 30 pseudosegments. Opisthosoma greenish, with dark spots as in C. simla (cf. fig. 980).

FEMALE (paratypes): Tibia 1: 6.9, 7.6. In general very similar to male, but darker. Epigynum flat, brown to dark brown, with blackish spot behind epigynum and pair of brown spots in front of epigynum (figs. 1010–1011); dorsal view as in fig. 1013, dorsoposterior view as in fig. 1012.

DISTRIBUTION: Known only from type locality.
