|Cat-eLog Data Sheet|
|Scientific Name||Chaetostoma lexa (Salcedo, 2013)|
|Type Locality||Mariano Dámaso Beraun, vicinity of Tingo María, Cueva de las Pavas, Quebrada Luconyupe, 9°22'15.1"S, 75°58'32.7"W, Provincia de Leoncio Prado, Departamento de Huánuco, Peru.|
|Pronunciation||KATE oh STOW mah - lex ah|
|Etymology||Greek, chaite = hair + Greek, stoma = mouth. The species lexa is in recognition of Alexandra Keane, sustainability activist. At the time of the publication of the species description was a Political Sciences student at the College of Charleston, USA.|
|Size||49mm or 1.9" SL. Find near, nearer or same sized spp.|
|Identification||The genus Chaetostoma is not straightforward to identify, but as a general rule, the species has spines behind the gill-cover (interopercular odontodes), no plates on the abdomen, and aside from C. platyrhynchus also lack plates on the snout edge. Different from Ancistrus by not having fleshy tentacles on the snout.|
|Sexing||The males have however a larger and broader head, slimmer ventral sides and disproportionately large pelvic fins. Perhaps the over-sized pelvic fins play a large role in the fertilization of the eggs. By inverting these over the clutch of eggs, they prevent the sperm cells being carried away by fast water current.|
|Distribution||Only known from clear water tributaries of the Río Huallaga near Tingo María (725–780 m), Departament of Huánuco, Peru.
