CHERAX (CHERAX) SUBTERIGNEUS, A NEW CRAYFISH (DECAPODA: PARASTACIDAE) FROM WEST PAPUA, INDONESIA

Cherax (Cherax) subterigneus n. sp., is a crayfish endemic to the Aitinjo Lake of West Papua, Indonesia. This species is one of the field-captured species from this region that are exploited for ornamental purposes. Its commonly used commercial name in the pet trade is Black Orange Tip Crayfish, Orange Tip Crayfish, or Red Tip Crayfish. The new species is genetically and morphologically similar to Cherax holthuisi, however, both species can be easily distinguished by certain morphological characteristics or by using sequence divergence, which is substantial, for considering C. subterigneus n. sp. as a valid species. We have also added a note about the probable incorrect subgeneric assignment of the Cherax peknyi and mandatory change of incorrect original spelling of recently described C. gherardii as C. gherardiae.
