Type locality. Brazil: Rio San Francisco near Villa Nova in the state of Bahia.

Type material. Lectotype (designated by Naviaux 2008), ♂ in SDEI, labelled: “ Rio S. Francisco / Bahia ” [ochre-tarnished, handwritten] // “ Garbe coll. / Melzer det.” [yellowish, handwritten] // “ Villa Nova / b. Donzeiro ” [ochre-tarnished, handwritten, the last word illegible] // “ Syntypus ” [dark red, printed] // “ Coll W. Horn / DEI, Eberswalde” [printed] // “Lectotype / Phaeoxantha / epipleuralis Horn, 1923 / R. Naviaux dét. 2008” [red, printed] .

Paralectotypes. 1 ♂, 7 ♀♀ in SDEI with same label data and: “leg. Garbe und Melzer” (see also Döbler (1973); only the paralectotypes illustrated here were examined by us.

Differential diagnosis. Phaeoxantha ( P.) epipleuralis is obviously morphologically close to P. ( P.) nocturna and P. ( P.) n. crassipunctata, but it may be distinguished by its differently shaped elytra ( Figs 85–86 View FIGURES 85–88 , 95, 97 View FIGURES 95–97 ) which are widest below the middle or with outer lateral margins slightly dilated towards apices (as in male LT, Fig. 86 View FIGURES 85–88 ); elytral surface is coarsely punctate, but the large punctures are present only on anterior two thirds; almost each puncture on the anterior elytral half is surrounded with a shadowed aura-like circle giving the punctures almost fovea-like appearance ( Fig. 96 View FIGURES 95–97 ). Body 9.50–11.0 (LT 10.0) mm long, 4.10–4.40 (LT 4.15) mm wide.

Distribution. Phaeoxantha ( P.) epipleuralis is known only from the nine type specimens from the type locality.
