Pholcophora hesperia Gertsch, 1982: 102 (only specimens from 12 mi E of Manzanillo; see Remarks under T. hesperia ).

Diagnosis

Distinguished from known congeners by the combination of: male genital bulb without dorsal ridge (unlike T. jalisco ); procursus tip gradually narrowing ( Fig. 44C View Fig ; unlike T. hesperia and T. sinnombre sp. nov.); male cheliceral apophyses wide apart ( Fig. 44A View Fig ; distance between tips ~65 µm, i.e., much wider apart than in T. huahua sp. nov. and T. oaxaca sp. nov.), in lateral view with small angle against distal-frontal face of chelicera ( Fig. 44B View Fig ; unlike T. hesperia ; not checked in T. jalisco ); main epigynal plate crescent-shaped ( Fig. 45A, C View Fig ; rather than band-like as in T. hesperia and T. jalisco ); sacs in female internal genitalia ~40–50 µm long ( Fig. 55E; i.e View Fig ., longer than in T. jalisco and T. oaxaca , shorter than in T. sinnombre ).

Etymology

The species name is derived from the type locality; noun in apposition.

Description

Male (holotype)

MEASUREMENTS. Total body length 1.10, carapace width 0.45. Distance PME-PME 40 µm; diameter PME 30 µm; distance PME-ALE 20 µm; distance AME-AME 10 µm; diameter AME 25 µm. Leg 1: 2.01 (0.55 + 0.15 + 0.50 + 0.48 + 0.33), tibia 2: 0.40, tibia 3: 0.37, tibia 4: 0.60; tibia 1 L/d: 7; diameters of leg femora 0.10, of leg tibiae 0.07.

COLOUR (in ethanol). Prosoma and legs monochromous ochre-yellow; abdomen slightly darker ochre-grey, also monochromous.

BODY ( Fig. 36E View Fig ). Ocular area barely raised. Carapace without thoracic groove. Clypeus unmodified, short (clypeus rim to ALE: 120 µm). Sternum wider than long (0.36/0.30), almost round (i.e., not heart-shaped), with pair of small but distinct anterior processes (~40 µm diameter at basis, ~40 µm long) near coxae 1. Abdomen globular; gonopore apparently without epiandrous spigots ( Fig. 46G View Fig ); ALS with seven spigots each ( Fig. 46H View Fig ).

CHELICERAE ( Fig. 44A–B View Fig ). With pair of frontal apophyses pointing downwards; distance between tips of apophyses 65 µm; without stridulatory files ( Fig. 46F View Fig ).

PALPS. In general possibly indistinguishable from congeners (cf. Figs 37 View Fig , 50 View Fig ); coxa unmodified; trochanter without process; femur proximally without process, distally widened but simple, slightly curved towards dorsal; femur-patella joints not shifted to one side; tibia very short, with two trichobothria; tibia-tarsus joints not shifted to one side; procursus very simple ( Figs 44C View Fig , 46A–B View Fig ), with distal ventral process; genital bulb large, complex ( Fig. 46A–B View Fig ), in light microscope possibly indistinguishable from congeners (cf. Figs 38D–F View Fig , 51D–F View Fig ).

LEGS. Without spines and curved hairs; with slightly increased density of short vertical hairs on tibia 1 (barely visible in dissecting microscope); retrolateral trichobothrium of tibia 1 at 61%; prolateral trichobothrium absent on tibia 1; tarsus 1 with four pseudosegments, all fairly distinct.

Variation (male)

Tibia 1 in six males (incl. holotype): 0.45–0.52 (mean 0.48).

Female

In general, similar to male ( Fig. 36F View Fig ) but sternum without pair of anterior humps. Total body length: ~1.20–1.30; tibia 1 in eight females: 0.43–0.47 (mean 0.45). Epigynum ( Fig. 45A–D View Fig ) short crescent-shaped anterior plate slightly protruding in lateral view; posterior plate wide, median part slightly protruding anteriorly. With distinct knob between epigynum and pedicel. Internal genitalia ( Fig. 45E–G View Fig ) with pair of strong transversal sclerites, pair of distinct sacs (receptacles?), without (or with very small?) pore plates.

Distribution

Known from type locality and one poorly specified neighbouring locality in Mexico, Colima ( Fig. 35 View Fig ). We do not have exact coordinates for Gertsch’s (1982) specimens from “ 12 mi. E Manzanillo”, but that locality is probably within a few km from the type locality.

Natural history

The spiders were very abundant in the dry leaf litter of a low thorn forest covering a hill near the Laguna of Cuyutlán ( Fig. 56B View Fig ).
