Ilyocryptus brevidentatus Ekman, 1905

Ilyocryptus brevidentatus Ekman 1905, p 5 –7, Plate 1: Figure 1 ; Kotov et al. 2002, p 2 –12, Figures 1 –72.

Syntypes: five parthenogenetic females and six exuvia, from localities 3–5 and 6–7, mixed in tube SMNH 5297 . It is not possible to select a lectotype, because Ekman, or a subsequent investigator, mixed all specimens from all localities in one tube .

Type locality

Not reported accurately; the species was described based on samples collected from South Georgia (localities 3–5 of Ekman 1905) and the Falkland Islands (localities 6–7).

Comments

This valid species was redescribed recently, and also found in the southernmost portion of the continental South America ( Kotov et al. 2002).
