Wangaraneus Mi, Wang & Li, 2024: 324.

Type species.

Wangaraneus yequ Mi, Wang & Li, 2024 from Yunnan, China.

Diagnosis.

This genus can easily be distinguished from other genera in the family by its modified palpal tibia, which has one to five ctenidia on its dorsal ramus. It can also be distinguished from other genera by the abdomen being blunt anteriorly and truncated posteriorly, with pair of posterolateral humps.

Description.

Carapace longer than wide, pear-shaped, reflective; median ocular area wider posteriorly than anteriorly. Cervical groove conspicuous in females and inconspicuous in males; fovea somewhat longitudinal in males and depressed in females. Chelicerae with four promarginal and two retromarginal teeth. Sternum cordiform. Legs yellow with brown annuli; coxa I with hook, and femur II with corresponding groove, tibia II with several macrosetae. Abdomen longer than wide, blunt anteriorly and truncated posteriorly, with pair of posterolateral humps; dorsum with intermittent longitudinal paler bands and one or two transverse paler bands, reflective. Male palp with two patellar bristles; palpal tibia bifurcated, dorsal ramus always with ctenidia; cymbium covering most of bulb in prolateral view; paracymbium finger-like (except flattened and incised distally in W. delicatus sp. nov.); bulb elliptical; tegulum smooth, with low ridge between bases of median apophysis and conductor; median apophysis wide at base, somewhat flattened, lateral side approximately equal to edge of tegulum; embolus tapered or thread-like; conductor tongue-shaped or triangular; terminal apophysis slender and membranous or absent. Epigynal plate wider than long, convex or flat; copulatory openings located on posterior, lateral, or ventral surfaces; copulatory ducts approximately equal length to spermatheca, or even longer; spermathecae spherical or kidney-shaped, either touching each other or separated.
