The holotype is double mounted (minuten in a block of plastic elastomer], is in good condition (some encrustation on head, especially eyes), and is deposited in the USNM. A female paratype (USNM) bears the same label data as the holotype.

We have observed this condition only in this species, and our observation is limited to the single holotype male.</paragraph>
