Coyle — Genus Aliatypus 
461 
Females: Carapace. Fig. 49. Thoracic groove a deep circular or 
longitudinally oval pit. Three or four large postocular setae form 
single, moderately long, row; sometimes additional tiny setae. AME’s 
relatively large and separated by less than diameter. Sternum. 
Fig. 69. Posterior sigilla small and far apart. Peripheral setae 
slender. Longest setae less common centrally than toward the pe- 
riphery. Genitalia. Figs. 149- 150. Seminal receptacle stalks ex- 
tremely weakly sclerotized, weakly sinuous (1-4 weak bends), and 
same diameter throughout length. Bulbs almost transparent and 
proportionately small to medium sized. Coloration. Pars thoracica 
pale yellow. Pars cephalica and chelicerae a darker pale brown. 
Distribution. Known only from the type locality (Map 2).

Aliatypus gulosus new species 
Figures 25-26, 59, 70, 85, no, 151-154. Map 2. 
Type specimens and etymology. Holotype male from Salt Creek, 
1.5 miles north of Dana Point, Orange Co., California, 6 December 
1968 (W. R. Icenogle). Three males and 17 female paratypes. The 
species name is a Latin adjective meaning gluttonous. 
Diagnosis. Males: The palpus (Fig. no) of A. gulosus is dis- 
tinctively different from that of all other species. The very loosely 
looped sperm reservoir, the closeness of the embolus base to the ICS 
base, the jagged, serrate inner (concave) edge of the OCS, and the 
evenly tapered conductor tip are some of the more distinctive palpus 
features. The distinctive, long banana shape of the pedipalpal tibia 
(Fig. 85) is expressed quantitatively by the excellent diagnostic 
ratios (Table 1) PTX/PTL and PTL/PPL. Females: The semi- 
nal receptacles (Figs. 1 51-154) of i. gulosus are distinctively dif- 
ferent from those of all other species. The stalks are short and 
straight and the bulbs are relatively large. The appropriate ratio 
selected from among the following will clearly distinguish A. gulosus 
from any other species (Table 2) : CL/IFL, CL/IML, CL/PSS, 
SW/PSS, SW/PSL, PSL/PSS, and IMS/PSS. Any of the last 
five ratios distinguish A. gulosus , with its small, widely spaced pos- 
terior sigilla, from the other southern California species (A. thomp- 
soni, A. plutonis, and A. torridus) .
