Distribution. Costa Rica, Panama, Ecuador, Venezuela. Bonatto (2001) listed Central America (except Mexico) and Trinidad. A single female specimen, labeled “ Brazil ”, Santa Catarina 1 ♀, Nova Teutonia, 27°11ʹS 52°23ʹW, 300–500 m, 19.iv.1965, F. Plaumann ( CNC) was examined, which clearly belongs to S. facialis . This is far from the known range this species and may be an example of mislabeling.

Remarks. Three specimens were successfully barcoded, from Costa Rica ( TLW 260, TLW 262) and Venezuela ( TLW 264). All sequences clustered together ( Fig. 488 View FIGURE 488 ). They formed a distinct group with some genetic variation between sequences. The genetic distance between sequences from Costa Rica and Venezuela was more than 3%, whereas between the two sequences from Costa Rica it was more than 5% ( Fig. 488 View FIGURE 488 ). This species is very distinctive and no significant morphological differences were seen between specimens from different areas.
