Funaxopsis Den Heyer & Castro, 2009

Historical review.

Den Heyer (1981b) described Cunaxoides passerinae , Cunaxoides vaneedeni , and Cunaxoides visci . Den Heyer and Castro (2009) erected Funaxopsis and transferred Funaxopsis passerinae , Funaxopsis vaneedeni , and Funaxopsis visci to the genus.

Diagnosis.

Gnathosoma. Pedipalps 3-segmented. Femurogenua at least twice as long as wide, complemented with 5 setae. Tibiotarsi at least twice as long as wide, usually complemented with 6 setae. A small apophysis occurs basally and a pointed process occurs near the terminal tip; a ridge runs between the apophysis and pointed process. Subcapitulum with 6 pairs of setae (hg1 - 4 and 2 pairs of adoral setae); setae hg4 is often longest. Chelicera without seta.

Idiosoma, dorsal. Proterosoma bears an ill-defined and weakly sclerotized shield complemented with 2 pairs of setae (lps and mps) and 2 pairs of setose sensillae (at and pt). Dorsal hysterosoma may or may not bear a plate; if plate present, it is ill-defined and weakly sclerotized, may be complemented with a variable number of setae, and may or may not be fused with the proterosomal shield. Setae c1 - h1, c2, and h2 present. Cupule im present laterad and posterior e1. Integument not covered in shields or plates striated.

Idiosoma, ventral. Coxae weakly sclerotized and ill-defined; they can be recognized by possessing somewhat denser striations than the surrounding integument. Coxae I-II may be fused and may coalesce medially to form a sternal shield. Coxae III-IV may be fused. Each coxa complemented with 2-4 setae. Genital plates each bear 4 setae (g1 - 4); 2 pairs of genital papillae visible underneath the plates. Anal plates bear 1 pair of setae; 1 pair of setae present ventrally on the integument near the anal plates. Up to 7 pairs of setae present on the integument between the coxal and genital plates. Cupule ih present ventrally laterad integumental setae associated with the anal plates. Integument not covered in shields or plates striated. Legs. Tibia III complemented with 1 bsl and 3, 4, or 5 sts. Tibia IV complemented with 3 sts (2 short, 1 long) and lacks a trichobothrium. Tarsi never constricted apically so as to end in lobes. Ambulacral claws on either side of a 4-rayed empodium present.
