Desognaphosa finnigan , new species Figures 271–274 ; Map 11

TYPE: Male holotype taken in a pitfall trap at an elevation of 850–950 m on Mount Finnigan, via Helenvale , 15 ° 49 ̍ S, 145 ° 17 ̍ E, Queensland (Dec. 3–5, 1990; D. Cook, G. Thompson, Roberts), deposited in QMB ( S28761 ) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males of this smaller species, found in the same general region as the preceding one, can easily be recognized by the prolateral projection at the tip of the terminal palpal elements (fig. 271); females resemble those of D. halcyon but have a much narrow­ er and smaller epigynal atrium (fig. 273).

MALE: Total length 4.6. Coloration as in D. malbon . Leg spination: tibiae: III v2­1p­ 2; IV v2­2­2, r0­1­1; metatarsi: III v2­0­2; IV v2­2­2, r0­1­0. Retrolateral tibial apophysis with subequal ventral, dorsodistal, and dorsoproximal prongs, paracymbial apophysis long, with recurved tip (fig. 272); embolus short, tip of twisted terminal palpal elements narrow, with prolaterally directed tubercle (fig. 271).

FEMALE: Total length 4.2. Coloration as in male. Leg spination: tibiae: III v2­0­2; IV v2­1p­2, r0­1­1; metatarsi: III v2­0­2; IV p0­ 1­0, v2­2­2, r0­1­0. Epigynal atrium with sinuous posterior margin (fig. 273); median epigynal ducts extending almost to sides of atrium (fig. 274).
