Description: The genera Paralithoxus has been reserected in a new paper (2018) by Lujan et al. and redescribing L. bovallii based on recently collected specimens from the upper Ireng River. Paralithoxus bovallii can be diagnosed from P. pallidimaculatus and P. surinamensis by having an adipose fin (vs. adipose fin absent), from P. boujardi, P. jariensis, P. planquettei, P. raso and P. stocki by having five or more predorsal plates (vs. four or, rarely, three), from P. boujardi, P. planquettei, and P. stocki by having paired fins irregularly banded (vs. paired fins uniformly coloured), from P. jariensis, P. planquettei, P. raso and P. stocki by having typically eight (rarely seven) interdorsal plates (vs. typically seven), from P. boujardi, P. raso and P. pallidimaculatus by having a uniformly or mottled brown body lacking white spots (vs. body having small, distinct white spots in P. boujardi and P. pallidimaculatus, or large indistinct spots in P. raso), from P. boujardi and P. stocki by lacking a marginal white caudal-fin band (vs. band present), and from P. boujardi and P. stocki by lacking enlarged odontodes on the anterodistal margin of the pectoral-fin spines (vs. enlarged pectoral-fin spine odontodes present on males and females). Colouration: Mottled light to dark brown dorsum, fins indistinctly and irregularly banded, no more than five indistinct bands on light brown base, abdomen and ventrum of anteromedial caudal peduncle translucent white, with melanophores dispersed around outer margin and concentrated around anal-fin origin, oral disc pale yellow. Aquarium Care: Quite a demanding genera which need pure, oxygen rich water. They need plenty of hiding places and the aquarium to be very strongly filtered. Diet: Insectivores that feed in their natural habitat from insect larvae on rocks. Feed Frozen mosquito larvae, brine shrimp and Daphnia. They will also except tablet foods. Remarks: Still found on some online sources as Lithoxus bovallii.
