Parabonzia Smiley, 1975

Historical review.

Atyeo (1958) described Bonzia bdelliformis from a tree hole in Tennessee, USA. Smiley (1975) erected Parabonzia for Bonzia bdelliformis . Den Heyer (1975) erected Cunabdella for Cunabdella marthae . Den Heyer (1977b) synonymized Cunabdella with Parabonzia and described Parabonzia athiasae . Kuznetzov and Livshitz (1979) reported Parabonzia from Russia. Smiley (1992) described Parabonzia mumai from Florida, USA. Corpuz-Raros (1996a) described Parabonzia mindanensis from the Philippines. Lin and Zhang (1998) described Parabonzia trioxys . Later they ( Lin and Zhang 2002) described Parabonzia zhangi . Skvarla et al. (2013) reported Parabonzia bdelliformis 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 multi-branched seta present dorsally on the telofemora. Tibiotarsi terminate in two strong setae. 2 pairs of adoral setae present or absent. Subcapitulum with up to 8 pairs of setae present.

Idiosoma, dorsal. Proterosoma bears a shield complemented with 2 pairs of setae (at and pt) and 2 pairs of setose sensillae (lps and mps). Dorsal hysterosoma may bear a shield; if a shield is present it 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 smooth. Cupule im is present laterad and caudally of e1. Integument that does not bear shields or plates is striated.

Idiosoma, ventral. Coxae I-II fused or not and coxae III-IV fused or not. Genital plates with up to 9 pairs of setae; 2 pairs of genital papillae visible underneath the plates. Up to 4 pairs of setae present on the anal plates. Up to 9 pairs of setae on the integument between coxae II and the anal plates. Legs. Trichobothrium on leg tibia IV present. The ambulacral claws occur on either side of a 4-rayed empodium.
