Wesmaldra , new genus

TYPE SPECIES: Wesmaldra bidgemia , new species.

ETYMOLOGY: The generic name is an arbitrary combination of letters considered feminine in gender.

DIAGNOSIS: Members of this genus resemble those of Cryptoerithus is having relatively short anterior lateral spinnerets, but lack the greatly enlarged posterior median eyes typical of that genus.

DESCRIPTION: Small to medium sized spiders, total length of males 1.7–3.9, of females 1.9–5.0. Carapace subcircular, cephalic area constricted, narrowed in front to less than half its maximum width, with or without cover of gray setae or recumbent scales; fovea longitudinal, weak. Eight eyes in two strongly procurved rows (fig. 7); PME largest, flat, situated posteriorly of other +

eyes, egg-shaped, not contiguous, silvery; AME second largest, circular, dark; ALE, PLE slightly oval, light; median ocular quadrangle slightly wider in back than in front, slightly longer than wide. Clypeus low, about J–K diameter of ALE, curved downwards. Sternum subcircular, flat, with only indistinct extensions between coxae but with long, triangular extensions to coxae; surface smooth with few long setae; posterior margin wide, separating coxae IV. Pedicel composed of one weak dorsal, one small ventral sclerite. Chelicerae with setae bordering distal, mesial margin, promargin; retromargin with 2–3 small teeth. Endites slightly convergent, obliquely depressed, rectangular, with promarginal scopula and serrula. Labium normally inverted u-shaped. Abdomen with or without weakly sclerotized orange scutum in males; cuticle normally with dense cover of gray, recumbent, stout scales or plumose setae; ALS ¹/ƽ– K of abdominal length, separated by about their diameter at base (fig. 14), tip with extremely long piriform gland spigots, triangular ventral tubercle containing few gland spigots. PMS, narrow contiguous; PLS slightly longer. Legs laterigrade, leg formula 4123, with sparse setae, few weak spines, coxae IV longest, about 1.2–1.5 times longer than III; trochanters not notched; femora I, II long, only slightly incrassate; tarsi III, IV distally with cracks; tarsi I, II with or without band of scaled, or short, bent, ventral setae, or tarsi I– IV ventrally with two rows of short, stout setae; tarsi with two relatively long claws bearing few or no teeth; claw tufts divided, consisting of few spatulate setae (figs. 21, 23), trichobothria present or absent on dorsal surface of patellae, tibiae, metatarsi, tarsi. Female palpal femur with line of 4–7 long, strong or thin, ventral setae. Male palpal cymbium long, slender, at least 2.2 times longer than wide, tip conical; conductor straight, distally situated; median apophysis reduced or cane-shaped, or longitudinal, rolled, with median pointed tip, or scoopshaped; terminal apophysis attached to median apophysis or embolus, triangular, or absent; embolus normally thin, straight, but can be with hooks or circular; sperm duct ushaped. Retrolateral tibial apophysis present or absent. Epigynal atrium normally present, anterior margin with or without epigynal hood.

DISTRIBUTION: The genus is known only from Western Australia and the Northern Territory.
