Swolnpes Main & Framenau, 2009: 278 View in CoL . Type species: Swolnpes darwini Main & Framenau, 2009 View in CoL , by original designation.

Diagnosis: Species of Swolnpes differ from all other Anamini by the inflated tarsus I in males ( Fig. 15F View Figure 15 ).

Description: Small nemesiid spiders. Coloration: mostly pale yellow.

Cephalothorax: Carapace ( Fig. 15A View Figure 15 ) weakly hirsute, with eight eyes in two rows; PME slightly smaller than other eyes; fovea slightly procurved. Maxilla ( Fig. 15E View Figure 15 ) with strongly produced basal heel; with numerous cuspules distributed over medial half and heel of each maxilla, not restricted to narrow band; maxillary serrula absent. Labium ( Fig. 15E View Figure 15 ) wider than long, slightly indented anteriorly, without cuspules. Coxal cuspules absent ( Fig. 15B View Figure 15 ). Sternum ( Fig. 15B View Figure 15 ) with three pairs of barely discernible sigilla; posterior pairs elongate, marginal.

Chelicera: absent; cheliceral furrow with several prominent promarginal teeth and several small granules basomesally; intercheliceral tumescence absent.

Pedipalp ( Fig. 15C, D View Figure 15 ): Male tibia uniformly setose, without patch of spinules on retrolateral face, and without asetose ventral depression; tarsus (cymbium) short and terminally blunt, without medial constriction (in lateral view); with simple pyriform bulb and tapering embolus; embolus not reflexed.

Legs: Male tibia I ( Fig. 15F View Figure 15 ) without ventral spur; metatarsus I not incrassate; scopula usually present on entire ventral tarsi of legs I and II, and lighter scopula on tarsi III and IV, and metatarsi I and II; tarsi without spines; tarsus I inflated; three claws, lateral claws each with two short rows of teeth; medial claw small and without ventral teeth.

Abdomen: Longer than wide. Two pairs of spinnerets; posterior median spinnerets unsegmented and separated by about diameter of spinneret; posterior lateral spinnerets three-segmented, apical segment elongate, digitiform.

Female genitalia ( Fig. 15G View Figure 15 ): One pair of small lobate spermathecae with accessory receptaculum.

Distribution: Species of Swolnpes are known only from the arid zone of southern Western Australia (see Main & Framenau, 2009).

Remarks: As noted above, the molecular analyses show that the genus Swolnpes is the sister group to Kwonkan . The two named species of Swolnpes and at least two undescribed species (S. MYG234 and S. MYG415) are known from museum collections ( Main & Framenau, 2009; this study).

Included species: Swolnpes darwini Main & Framenau, 2009 ; and S. morganensis Main & Framenau, 2009 .
