D i a g n o s i s: The genus Ellipotoma SPINOLA, and its 2 previously described species, were discussed in OPITZ (2006). The available specimen of Ellipotoma makrosa superficially resembles those of E. turmalis OPITZ, from which the E. makrosa specimen differs by showing a narrower head, narrower vertex, and the posterior1/4 of the elytra are not flared as they are in specimens of E. turmalis.

Color: Forebody and pterothorax black; antennal fundus yellow, capitulum black; elytra yellowbrown, asetiferous punctures darker; legs yellow. Head: Antenna (Fig. 90) capitate, 6 th funicular antennomeres slightly expanded, capitular antennomeres 8 and 9 transverse, antennomere 10 slightly oblong; eyes large, finely facetted, ocular notch large, eye wider than frons (EW/FW 18/3). Thorax: Pronotum (Fig. 162) oblong (PW/PL 50/40), disc finely punctate, lateral tubercle absent; discal and lateral trichobothria prominent; elytral asetiferous punctures arranged into 9 striae (EL/EW 185/35); anterior margin of protibia with 10 spines. Abdomen: Lost.

N a t u r a l H i s t o r y: The available specimens were 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, makrosa, stems from the Greek macros (= long); in reference to the long narrow body form of this beetle.
