Palp
Cymbium with a projection; prolateral side of paracymbium unpigmented and unsclerotized, numerous setae and spines at the tip of paracymbium (
Fig. 6F, G
). Contrategulum has two marginal apophyses with smooth margin and blunt distal end (
Fig. 6H
). Tegulum with a dentate, wide edge (
Fig. 6F, G
). Conductor with a spiniform apex and a small apophysis at posterior part, parallel with embolus (

Female genitalia
Posterior part of genital area rectangular (
Fig. 6B– E
), with pair of receptacular clusters with genital stalks (
Fig. 6B, C
), or with paired receptacular clusters fused into a big cluster (
Fig. 6D, E
).
Variation
Female receptacular clusters show considerable intraspecific variation, with the pair of receptacular clusters fused.
