French Guiana: Subdivision Maripasoula, Massif du Mitaraka, 21°4'N- 54°27'W, 25-II-26-III-2015, La Planète Revisitée- MNHN.PNI Guyane, 2015 (APA-973-1) (MNHN, 4; WOPC, 1), Subdivision Roura, Amazon Nature Lodge, Kaw Road 6, 11-23-VIII-2017, Malaise, Morris & Wappes (RFMC, 1)..

D i a g n o s i s: The genus Epiphloeus SPINOLA was revised in 2008 (OPITZ 2008). That work included a key to Epiphloeus species. Epiphloeus mantillerii specimens key out to E. princeps GORHAM, from which E. mantillerii specimens differ by showing a predominantly black basal 1/2 of the elytral disc; a short flavotestaceous macula extends backward from the humeral angle. Also, in E. mantillerii specimens there is a much more extended phallobasic rod.

D e s c r i p t i o n: Size: Length 13.0 mm; width 3.0 mm. Form: As in Fig. 289. Color: Cranium castaneous, frontal margin, below ocular notch, with slender patch of white setae; antenna bicolorous, scape testaceous, infuscated dorsally, rest of antenna brown; prothorax black, except, middle of arch red; pterothorax testaceous; elytra bicolorous, each disc with short testaceous flavotestaceous macula at humeral angle and large angular flavotestaceous maculae behind middle; abdomen bicolorous, visible sternites I to IV yellow, sternites V and VI black; pronotal and elytral discs densely vested with recumbent white setae. Head: Antenna (Fig. 88) capitate, scape particularly elongate, funicular antennomeres tightly packed, capitular antennomeres 9 and 10 with extended angular anterodistal margin, antennomere 11 suboval; eyes large, finely facetted, ocular notch large, eye wider than frons (EW/FW 55/45). Thorax: Pronotum (Fig. 175) transverse (PW/PL 150/120), anterior transverse depression deeply impressed; arch finely transversely wrinkled, disc coarsely punctate, lateral tubercle well developed, disc concave paralaterally near pronotal collar; discal and lateral trichobothria prominent; each elytron tapered to apex; elytral asetiferous punctures large, concentrated on elytral basal 1/4 (EL/EW 125/45); anterior margin of protibia with 10 spines. Abdomen: Pygidium transverse / scutiform; aedeagus as in Fig. 220.

Variation: Length 8.0-13.0 mm; width 2.0-3.0 mm. The pronotal arch may be entirely black.

N a t u r a l H i s t o r y: The available specimen was collected during a period from 25 February to 26 March 2015.

D i s t r i b u t i o n: This species is known from French Guiana.

E t y m o l o g y: The trivial name, mantillerii, is a dedicative patronym to honor Antoine Mantilleri, MNHN, for his contributions to taxonomic Entomology.
