Cunaxatricha Castro & Den Heyer, 2008

Historical review.

Castro and Den Heyer (2008) erected Cunaxatricha for Cunaxatricha tarsospinosa .

Diagnosis.

Gnathosoma. Pedipalps 5-segmented and end in a strong claw. They extend beyond the subcapitulum by at least the last segment; apophyses absent. Basifemora complemented with a long simple seta; telofemora complemented with a short simple seta. These two segments fused, although a line remains visible and they can thus be differentiated. Subcapitulum complemented with 6 pairs of setae (hg1-4 and 2 pairs of adoral setae). Setae hg4 located between hg2-3 instead of in the coxal region. Chelicera with seta present.

Idiosoma, dorsal. Female dorsal idiosoma bears a sclerotized shield that bears 2 pairs of setose sensillae (at and pt) and 2 pairs of simple setae (lps and mps). Idiosomal shield reticulated. 7 pairs of setae, c1-2, d1-h1, present. Cupule im present, usually posteriolaterad of e1. Integument striated.

Idiosoma, ventral. Coxae I and II fused, as are coxae III and IV. 6 pairs of setae present between and posterior to the coxae. Genital plates each bear 4 setae; 2 pairs of genital papillae not visible underneath the plates. Integument between plates striated and bears 4 pairs of additional setae. Legs shorter than the body. Leg 4 longest. Famulus on tarsi I normally shaped and set in a deep depression. Tarsi slightly constricted apically, resulting in small tarsal lobes. Basifemora and telofemora of legs I and II partially fused. A trichobothrium on leg tibia IV absent. Ambulacral claws on either side of a 4-rayed empodium present.
