Name
Denheyernaxoides Smiley, 1992 – Wikispecies link – Pensoft Profile
Historical review
Canestrini (1885) described Eupalus brevirostris. Berlese (1894[1], 1897[2]) redescribed Eupalus brevirostris and provided illustrations of the dorsal idiosoma, chelicera, and palp. Baker and Hoffmann (1948)[3] proposed Cunaxoides as nomen novum as Eupalus was preoccupied. Smiley (1992)[4] erected Denheyernaxoidinae and Denheyernaxoides for Denheyernaxoides martini. Lin (2001)[5] moved transferred Cunaxoides brevirostris to Denheyernaxoides and redescribed the species based on specimens from China. Den Heyer (2009)[6] considered Denheyernaxoidinae as a junior synonym of Cunaxoidinae. Den Heyer and Castro (2009)[7] considered Denheyernaxoides to belong to Cunaxoidini. Sergeyenko (2011) reported Denheyernaxoides brevirostris from Ukraine and erected Denheyernaxoidini for 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 4 pairs of setae (hg1–4); setae hg4 often the longest. Adoral setae absent. Chelicera without seta.
Idiosoma, dorsal. Proterosoma lacks a shield, complemented with 2 pairs of setae (lps and mps) and 2 pairs of setose sensillae (at and pt). Dorsal hysterosoma lacks a plate. Setae c1–h1, c2, and f2, h2 present. Cupule im present laterad and posterior of e1. Integument not covered in shields or plates is striated.
Idiosoma, ventral. Coxae I–II connected by small apodemes. Coxae III–IV 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. 5 pairs of setae present on the integument between the coxal and genital plates. Cupule ih present ventrally laterad the integumental setae associated with the anal plates. Integument not covered in shields or plates is striated. Legs. Femora I and II not divided. Trichobothrium on tibia IV absent. Tarsi never constricted apically so as to end in lobes. Ambulacral claws on either side of a 4-rayed empodium present.
