Opitz // [large red label] HOLOTYPE ♂ Thisiomorphus curticornis Pollock ”, in FSCA. Derivation of specific epithet. From a combination of the Latin “ curtus ” (short) and “ cornu ” (horn), in reference to the distinctly short antennae of the holotype. Diagnosis. The single specimen of this new species possesses very short antennae, not extending past half length of pronotum; this is unique in the genus. Description. Measurements (mm, N = 1): HL = 0.88; PL = 0.88; EL = 3.16; GHW = 1.16; GPW = 1.24; GEW = 1.92; TL = 4.92. Ratios: EL/GEW = 1.65; GPW/PL = 1.41; TL/GEW = 2.56; GPW/GHW = 1.07. With characters of Thisiomorphus, and the following: Body narrowly oval (TL / GEW 2.56), lateral elytral margins slightly arcuate. Color. Antennae rufotestaceous; maxillary palpi uniformly rufous; head, pronotum and scutellum concolorous, dark brown; elytra dark brown, slightly lighter in color than forebody; femora and tibiae brown, femora slightly lighter distally; tarsi dark rufous; venter uniformly brown. Antennae very short; antennomeres 3–7 subfiliform; antennomeres 8–10 short, nearly moniliform, only slightly widened distally. Pronotum moderately wider than long (GPW / PL 1.41), subequal in width to head (GPW / GHW 1.07); lateral margins subparallel basally, arcuate in anterior half, maximum width near midlength; dorsal surface evenly convex, without depressions. Male genitalia. Parameres distinctly shorter than lateral margin of basale, inner margins very slightly sinuate basally; basale with anterior margin slightly curved, lateral margins straight for their entire lengths. Distribution. The only known specimen is from northeastern ECUADOR (Sucumbíos).Published as part of Pollock, Darren A., 2016, Revision of Thisiomorphus Pic (Coleoptera: Mycteridae: Eurypinae) with descriptions of eleven new species from Central and South America and a key to genera of Neotropical Eurypinae, pp. 301-322 in Zootaxa 4093 (3) on page 315, DOI: 10.11646/zootaxa.4093.3.1, http://zenodo.org/record/26410
