a distinct protrusion of the cuticle...
Taxonomic remark "In the original description, H. isaitshikovi Filipjev, 1927 is unique in possessing
a distinct protrusion of the cuticle around the cloaca; however,
none of the later redescriptions refers to this character. Furthermore, H.
isaitshikovi as described by Allgén (1932) and Schuurmans Stekhoven Jr
(1935) lacks lateral alae; the specimen described by Bresslau and Schuurmans
Stekhoven (1940) also lacks lateral alae and has a precloacal sensillum
(not described by Filipjev 1927). The redescription provided by Allgén
(1946) is entirely insufficient to identify the species. In the redescriptions
by Platt and Warwick (1983) and Zhang and Huang (2005), ornamented
caudal alae are present. Since none of these features were recorded by
Filipjev (1927), we consider all these redescriptions species inquirendae." [details]
