Priscula limonensis
González-Sponga, 1999: 141
, figs 29–37 (♂ only, see Notes below).
Notes
González-Sponga (1999)
did
not
separate the male
holotype
from the other specimens, i.e., there is no MAGS 1214a and 1214b. In addition, the vial MAGS 1214 contains two males rather than just one, so it is
not
obvious which specimen is the
holotype
. Since there is no reasonable doubt that both males are conspecific, there is currently no need for selecting a
lectotype
and they are simply treated as types.
González-Sponga (1999
: figs 36–37) obviously used a juvenile for his drawings of the ‘female’. The female has a highly distinctive rounded process on the epigynum (
Figs 876
,
915
,
921
) that reminds of
P. lagunosa
González-Sponga, 1999
(cf.
Figs 909
,
917
) but is larger and rounder. Females of two further similar undescribed species are available in collections: The MIZA has two females of a species with similar epigynal process, but in that case the process is directed more towards the front (MIZA 105757, MAGS 1389, from Pico Codazzi); the ZFMK has a female with a similar but much lower epigynal process (ZFMK, Ven20-182, from El Ávila National Park, near La Julia, trail to Rancho Grande).

Description of female
Habitus as in
Figs 875–876
. Carapace with dark median mark and lateral bands, without radial marks; sternum dark brown, medially slightly lighter. AME either tiny (diameter in
paratype
:
20 µm
), or with dark pigment but without lenses (one of the newly collected females). Legs with dark rings on femora (incomplete ring proximally, complete rings at half-length and subdistally), on tibiae (proximally, at half length, and subdistally), and metatarsi (proximally). Tibia
1 in
two newly collected females: 3.8, 4.2. Epigynum with distinctive rounded process (
Figs 914–915
,
920–921
), with dark transversal band separating anterior hairless area from hairy rest of epigynal plate. Internal genitalia (newly collected female;
Figs 911
,
922–923
), with pair of oval pore plates, simple evenly rounded anterior ‘valve’.
Distribution
Known from El Limón area only, in
Venezuela, La
Guaira (Fig. 1061).
Natural history
The
types
were collected from overhanging road cuts composed of grasses, leaf litter and soil, in a secondary forest with coffee and banana plants (
González-Sponga 1999
). The newly collected specimens were found in small holes and cavities in the ground in a well preserved humid forest fragment.
