Notes

Identification to species level follows Isbrücker (1981), Thomas and Rapp Py-Daniel (2008) and Thomas and Sabaj Pérez (2010) based on the following characters: elongate lip filaments; three premaxillary teeth per ramus; premaxillary teeth approximately twice as long as dentary teeth; developed odontode crests on head and dorsal trunk plates; 34 lateral plates; 19 coalesced lateral plates; dorsal fin spine not elongated (24% of SL); post-orbital notch relatively well developed; abdomen mostly plated (with the exception of an anterior v-shaped naked area over the pectoral girdle); and all fins except anal fin with dark sub-distal bands (most prominent on caudal and dorsal fins). Identification of this species is tentative, as there appears to be considerable variation in the L. cataphracta group. We await the forthcoming systematic revision of the genus (as mentioned in Thomas and Sabaj Pérez 2010).

One individual was caught by hand from shallow, fast flowing water over a rocky/sandy substrate (sampling site NH05). The live specimen is pictured in Fig. 26.
