Neobonzia Smiley, 1992

Historical review.

Berlese (1910) described the first species of Neobonzia , Scirus parvirostris . Thor and Willmann (1941) moved Scirus parvirostris to Cunaxa . Baker and Hoffmann (1948) described Cunaxa snowi . Heryford (1965) described Cunaxa reticulata . Smiley (1975) erected the genus Pseudobonzia , with Cunaxa reticulata as the type species. Den Heyer (1977c) redescribed Pseudobonzia , moved Coleoscirus parvirostris to Pseudobonzia , and described six new species from South Africa: Pseudobonzia argillae , Pseudobonzia nona , Pseudobonzia lootsi , Pseudobonzia themedae , and Pseudobonzia saaymani . Pseudobonzia parilis was described by Chaudhri (1977). Den Heyer (1980b) described Pseudobonzia smileyi and transferred Cunaxa snowi to Pseudobonzia . Chaudhri (1980) described Pseudobonzia numida . Luxton (1982) described Pseudobonzia breviscuta from New Zealand peat moss. Liang (1983) reported Pseudobonzia themedae from China. Pseudobonzia shanghaiensis was described by Liang (1984). Smiley (1992) described Pseudobonzia newzealandicus , Pseudobonzia landwehri , and Pseudobonzia summersi ; reported Pseudobonzia saaymani from the USA and Canada; and erected a new monotypic subfamily, Neobonzinae , and genus, Neobonzia , for Neobonzia moseri . Corpuz-Raros and Garcia (1996) described two species from the Philippines, Pseudobonzia gruezoi and Pseudobonzia longispina . Hu (1997) reported Pseudobonzia shanghaiensis and Pseudobonzia themedae from China. Sergeyenko (2005) described Pseudobonzia kuznetzovi . Pseudobonzia clavata was described by Corpuz-Raros (2008). Den Heyer and Castro (2008b) split a new genus, Coleobonzia , from Pseudobonzia ; They retained 6 speciesin Pseudobonzia ( Pseudobonzia clathratus , Pseudobonzia delfinadobaakerae , Pseudobonzia landwehri , Pseudobonzia neoreticulata , Pseudobonzia reticulata , and Pseudobonzia yini ) and transferred all other species to Coleobonzia and described Coleobonzia clava and Coleobonzia moraesi . Bashir and Afzal (2009) described Pseudobonzia bakari , Pseudobonzia malookensis , and Pseudobonzia shamshadi . Den Heyer (2011) synonymized Coleobonzia with Neobonzia and moved Neobonzia to Coleoscirinae , effectively disregarding Neobonzinae .

Diagnosis.

Gnathosoma. Pedipalps 5-segmented and reach beyond the subcapitulum by at most the distal half of the last segment. Simple setae present on the basi- and telofemora. Pedipalp tibiotarsi long and S-shaped (as opposed to short and cylindrical as in Neoscirula ). Subcapitulum with 4 pairs of setae (hg1-4). 2 pairs of adoral setae present. Chelicera with seta usually present. Extensive reticulated pattern absent from the gnathosoma, though a row of single cells may be present caudally.

Idiosoma, dorsal. Plates lightly sclerotized and may not be well defined or demarcated. Proterosomal plate bears 2 pairs of setae (lps and mps) and 2 pairs of setose sensillae (at and pt). Extensive reticulated pattern absent, although a pair of rows of up to 6 cells may be present. Proterosomal plate may be covered with random dots or papillae. Hysterosomal plate absent. Setae c1 - h1, and usually c2 and f2 present dorsally; h2 present or absent. Cupules im present laterad and sometimes caudally of e1. Integument striated.

Idiosoma, ventral. Coxae usually restricted to the trochantral bases, though sometimes coxae I-II may nearly touch medially. Coxae I-II fused. Coxae III-IV fused. All coxae lightly sclerotized and may be ill-defined. Extensive reticulated pattern absent from the coxae, though a row of cells or reticulated pattern may be present near the edges. Coxae may be covered with random dots or papillae. Coxae I-IV usually have the simple setal formula 3-3-3-3 ( Neobonzia parilis is the exception with 2-2-3-2). Genital plates each bear 3-4 setae; 2 pairs of genital papillae visible underneath the plates. 2 pairs of setae (ps1 - 2) usually occur on the anal plates and 1 pair of setae (pa) occurs on the integument near the anal plates. However, at least one species ( Neobonzia clavata ) has 3 pairs of setae present on the anal plates and 0 pairs of setae on the integument. Cupules ih present ventrally near the anal plates. Legs. Tarsi never constricted apically so as to end in lobes. The apices of solenidia cylindrical, not swollen as in Coleoscirus and Scutascirus . Trichobothrium on leg tibia IV present. Ambulacral claws rippled and occur on either side of a 4-rayed empodium.

Key to adult female Neobonzia

As suggested by Den Heyer (2013) Pseudobonzia bakari , Pseudobonzia malookensis , and Pseudobonzia shamshadi are transferred to Neobonzia .

Neobonzia parvirostris (Berlese, 1910) is known only from the male and so is not included in the key. Neobonzia breviscuta (Luxton, 1982) is not included in the key as an insufficient number of characters are given in the original description.
