Remark: See Le Bail et al. (2000:244, fig.) for a complementary description with biological observations and geographical distribution, also Nijssen & Isbrücker (1990:tab. 1) and Muller & Isbrücker (1993:75) for morphological data of types.
Comments: Inhabits stony rivulets (Ref. 6868); has been collected in little forest tributaries (3 to 4 m wide) with shallow depth, rocky bottom, strong current, often with cascades.  Likewise, during the dry season, it has been found in a split brook with very little water input, where only 2 species of <i>Rivulus</i> (<i>R. igneus</i> and <i>R. cladophorus</i> were present, thus suggesting that <i>Lithoxus</i> is a pioneer species which is capable of colonizing difficult environments which are nutritionally poor (Ref. 35381).
