Author Kalúz, S. text Acarologia 2012 2012-06-22 52 2 165 172 http://dx.doi.org/10.1051/acarologia/20122046 journal article 10.1051/acarologia/20122046 2107-7207 5403938 Genus Ceratorchestes Balogh and Mahunka, 1969 Type species: Ceratorchestes setosus Balogh and Mahunka, 1969 Generic characters were proposed by Balogh and Mahunka (1969a) , by J. Balogh and P. Balogh (1988) , and also summarized by Balogh (1972) , J. Balogh and P. Balogh (1988 , 1992 ). The diagnosis is presented with our additions and changes below. Generic diagnosis — Peloppiidae with the following combination of characters: prodorsal setae and sensilli well-developed, setiform; lamellae thin, long, with minute cusp; translamella present or absent; rostrum incised, pointed or truncate; tutoria long, with short point, free tip; lateral sides of prodorsum with tooth; notogaster with 10 pairs of setiform notogastral setae (nine pairs long, one pair c minute or represented by alveoli); dorsal notogastral setae inserted in two subparallel rows; dorsophragmata and pleurophragmata present; epimeres III + IV unusually elongated or normal; sejugal apodeme interrupted medially; epimeral border IV transverse; epimeral setal formula 3-1-3-5; adanal setae setiform, ad 1 and ad 2 in paraanal position, ad 3 in preanal position; chelicerae chelate-dentate; legs with three claws. Remark — Balogh and Mahunka (1969a) have proposed also following generic character - legs IV are jumping legs. In our opinion, this statement is an assumption and requires evidence, therefore we have not included it in the generic diagnosis.
