Cylindridia sanguinea (HUSTACHE) , comb. n.

Torcus sanguineus Hustache, 1939: 117 .

Diagnosis:

Cylindridia sanguinea ( Fig. 3, 7) can be confused with C. latisquama ( Fig. 2, 6; see diagnosis of that species) and possibly Torcus variabilis ( Fig. 4, 8), which has similar vestiture and habitus. The latter can be distinguished easily by the row of erect white setae above the eye. All male C. sanguinea from San Fernando have the prosternal spines abruptly bent at the base (the specimen from Tigre is a dwarf male without spines), but it is not known if this character varies between local populations. The specimens measured 3.5-4.7 mm (standard length 3.2-4.3 mm) and were approximately in the same size range as C. latisquama and T. variabilis .
