| Comment | |
| Etymology | Named after Professor Andrzej Kruk (born 1971), the current Dean of the Faculty of Biology and Environmental Protection at the University of Łódź, Poland, for his friendship and his influential contribution in enhancing the quality of research at the University of Łódź. The name is a noun in the genitive case. The generic name is derived from the river name “Paikwa” (referring to the type locality) and the Greek ‘ophis’ (meaning snake). |
