Microglanis xylographicus Ruiz & Shibatta, 2011

Family:  Pseudopimelodidae (Bumblebee catfishes, dwarf marbled catfishes)
Max. size:  2.78 cm SL (male/unsexed)
Environment:  benthopelagic; freshwater
Distribution:  South America: Brazil. Known from tributaries of the rio das Mortes and small nearby direct tributaries of the rio Araguaia such as the córrego Jaraguá and rio das Garças, in States of Mato Grosso and Goiás, Brazil (Ref. 88956).
Diagnosis:  Microglanis xylographicus is easily distinguished from its congeners by two characters related to color pattern: (1) trunk brown with horizontal light stripes that in conjunction impart a tree-bark pattern, and (2) absence of any light marks (blotch or transversal band) crossing the occipital region. The new species can be further distinguished from its congeners, except Microglanis robustus, by the neuromasts surrounded by melanophores, forming three series of aligned small black points laterally on the trunk, four series in the head, one series on the lateral of nape, and one series posterior to the nape. It is distinguished from M. robustus by having a relatively long snout 11.4-12.9% SL (vs. 9.1-10.7% SL), and five pleural ribs (vs. 6 or 7) (Ref. 88956).
