Etymology: Andeancistrus: Derived from 'Andean', a reference to the mountains from which this genus originates, and 'ancistrus', a root name for many Hypostominae genera that have clusters of enlarged evertible cheek; eschwartzae: Named for Ms. Eugenia Schwartz, an artist and benefactor whose generous support through the Coypu Foundation made this research possible.
Eponymy: Eugenie ‘Ersy’ Chavannee Schwartz (1951–2015) was a New Orleans-based artist and benefactor – a surrealist sculptress – who financially supported the expedition that collected the holotype of Hyphessobrycon eschwartzae and whose support through the [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 8; Anal soft rays: 3 - 4. Andeancistrus eschwartzae is distinguished from its only congener, A. platycephalus, by possessing black to dark gray base color of head and body (vs. light gray), irregularly shaped round to vermiculate yellow-gold spots smaller than half naris diameter evenly distributed across head, lateral and dorsal surfaces of body and fin rays (vs. white to blue uniformly round spots), and by the absence of enlarged clusters of odontodes (keels) at posteromedial apex of most lateral body plates (vs. presence of odontode clusters) (Ref. 104644).
