Bonzia Oudemans, 1927

Historical review.

Oudemans (1927) erected Bonzia for Bonzia halacaroides . Willmann (1939) described Bonzia sphagnicola from Germany. Willmann (1950) described Bonzia rufofusca . Bonzia brownei was described by Turk (1972). Den Heyer (1977) provided a detailed redescription of type material of this genus. Kuznetzov and Livshitz (1979) reported Bonzia from Russia. Michocka (1987) reported Bonzia halacaroides from Poland. Smiley (1992) described Bonzia woodi and Bonzia yunkeri and synonymized Bonzia rufofusca and Bonzia brownei with Bonzia halacaroides . Skvarla et al. reported Bonzia yunkeri from the Ozark Mountains in Arkansas.

Diagnosis.

Gnathosoma. Pedipalps 5-segmented and reach beyond the subcapitulum by at most the distal half of the tibiae. Apophyses absent. A dorsal multi-branched seta present on the telofemora. The tibiotarsi terminate in a stout claw. 2 pairs of adoral setae present or absent. Subcapitulum with 4 pairs of setae (hg1 - 4) present. Setae hg1 are geniculate.

Idiosoma, dorsal. proterosoma bears a shield complemented with 2 pairs of setae (at and pt) and 2 pairs of setose sensillae (lps and mps). The dorsal hysterosoma bears a shield that may be complemented with a variable number of setae depending on the extent of the shield. Setae c1 - h1, c2, f2 and h2 present, and are smooth or spiculate. Cupule im present laterad and caudally of e1. Integument that does not bear shields or plates is striated.

Coxae I-II fused and coxae III-IV fused. Genital plates bear 4 setae; 2 pairs of genital papillae visible underneath the plates. 4 pairs of setae present on the anal plates. Trichobothrium on leg tibia IV present. Ambulacral claws occur on either side of a 4-rayed empodium.
