Diagnosis
Female
- empodia I-IV = stout claw, half the length of the tenent hairs on the true claws (Figs 1-3)
- true claws I-IV = short pad with two tenent hairs (Fig. 3)
- peritreme ending in simple expansion
- prodorsum with fine longitudinal striae, forming a broad U-shape posteriorly (Fig. 4)
- dorsal opisthosomal cuticle with fine striae, transverse medially becoming longitudinal laterally (Fig. 5)
- dorsal setae short, blunt and barbed, much shorter than distance to next setae (Figs 5-7)
- pregenital striae longitudinal (Fig.8 )
- legs shorter than body (Fig. 9)
- tarsus I solenidion long, tarsus II solenidion short and slightly swollen at base (Figs 10-13)
- ft setae on tarsi I-IV with spatulate/fimbriate tips (Figs 11-13)
- palp solendidion short, spindle-shaped (Fig. 14)
- brownish yellow when alive, with large brown spherical inclusions
Male as per female plus:
- body slightly more tapered posteriorly than female (Fig. 15)
- prodorsum with strong longitudinal striae, forming a broad U-shape posteriorly (Fig. 16)
- dorsal opisthosomal setae f1 inserted more lateral than e1, inserted just anterior to f2 (Fig. 17)
- tarsus I solenidion ω″ long (Figs 18, 19), tarsus II-IV solenidia all short (Figs 19, 20)
- ft setae on tarsi I-IV with spatulate/fimbriate tips (Figs 19, 20)
- palp with solenidion short, spindle-shaped (Fig. 21)
- aedeagus directed dorsally, with no anterior or posterior projection; dorsal margin of shaft at 30° angle to ventral margin; dorsal projection short stout finger-like, bent dorsally at 45-50° angle, weakly tapering, with tip curving posteriorly (Fig. 22)
