Eucteniza cabowabo sp. n. 'The Cabo Wabo Trapdoor Spider’Figs 1, 37-42

Type material.

Male holotype and female paratype (EU096), from Baja California Sur, Mexico, 8mi SE of La Paz, 24.0338, -110.2331 4, 287m, coll. E. L. Sleeper, F. J. Moore 13.x.1968. Male holotype and female paratype deposited in AMNH.

Etymology.

The specific epithet is a noun taken in apposition inspired by Sammy Hagar’s club and restaurant, Cabo Wabo, in Cabo San Lucas.

Diagnosis.

Male Eucteniza cabowabo specimens differ from all other Eucteniza specimens by having a very slender leg I tibia and metatarsus with thin ventral megaspines (Figs 3-40, 42); PME’s reduced in size. The single Eucteniza cabowabo female paratype lacks PME’s; due to the lack of specimens it is not clear whether this is a diagnostic feature or the specimen is aberrant.

Description of male holotype.

Specimen preparation and condition. Specimen preserved in 70% EtOH. Pedipalp, leg I, and leg II left side removed, stored in vial with specimen. Coloration faded. General coloration. Carapace dark reddish brown 2.5YR 2.5/4 (Fig. 37). Abdomen very dusky red 2.5YR 2.5/2. Cephalothorax. Carapace 5.25 long, 4.19 wide, glabrous, lacks fringe, pars cephalica low. Foveal groove deep and procurved. Tubercle absent. AER slightly procurved, PER slightly recurved. AME slightly larger in diameter than PME. Sternum moderately setose, STRl 3.04, STRw 2.48. Posterior sternal sigilla large, irregularly shaped, and contiguous, medial pair anterior sigilla more centrally positioned, irregularly shaped. Chelicerae with anterior tooth row comprising 6 teeth, posterior margin with single straight row of 4 teeth. Lacks palpal and labium cuspules, LBw 0.83, LBl 0.45. Rastellum consists of 8 spines. Abdomen. Moderately setose. Legs. Leg I: 5.44, 2.38, 3.88, 4.19, 2.31; leg IV: 5.69, 2.38, 4.69, 4.75, 3.19. Light scopulae on legs I, II, III, IV. Tarsus with 10 trichobothria, widely spread.
