Chorizococcus McKenzie, 1960

Chorizococcus McKenzie 1960: 692; 1967: 86; Miller and Mckenzie 1971: 569; Williams 1970: 124; Williams, 1985: 75; Williams 2004: 106; Williams and Watson 1988: 31; Williams and Granara de Willink 1992: 100; Ben-Dov 1994: 82.

Diagnosis.

Body elongate oval to broadly oval; membranous. With 1-5 pairs of cerarii present on posterior segments of abdomen and sometimes a pair on head also, each cerarius bearing 2 conical setae; auxiliary setae present on anal lobe pair only. Oral rim ducts, sometimes of 2 sizes, present on dorsum and commonly also on venter. Oral collar tubular ducts present, at least on venter; if present on dorsum, then restricted to marginal areas. Antennae each with 7 or 8 segments. Legs well developed, with translucent pores on hind coxae, sometimes absent. Claw stout, without a denticle. Claw digitules knobbed. Tarsal digitules minutely knobbed. Multilocular disc pores present on venter, rarely found on dorsum. Circulus present or absent, when present usually divided by intersegmental line. Anal ring normal, bearing 6 setae. Anterior and posterior ostioles present.

Comments.

Chorizococcus McKenzie comes close to Vryburgia De Lotto in possessing dorsal oral collar tubular ducts. Oral collar tubular ducts on dorsum in Chorizococcus occur on margin only, whereas in Vryburgia , those ducts occur in transverse rows on dorsum ( Williams 2004). Spilococcus Ferris is almost identical with Chorizococcus McKenzie but possesses 6-17 pairs of cerarii, six or more of which present on the abdomen. Miller and Mckenzie (1973) discussed the difficulties of assigning species to either Chorizococcus or Spilococcus . Danzig (1998) did not accept Chorizococcus and included all species with 1-17 pairs of cerarii in Spilococcus sensu lato. Here we follow the definition of Wiliiams (2004) and accept the usage of Chorizococcus McKenzie.
