Lectotype female at MHNG ( Ratcliffe 2004 ), examined. Type locality: “Brasilia” on the specimen label but “ Mexique ” in the original description. Gory and Percheron did not indicate in their description how many specimens they had. The lectotype does not have the same markings as the specimen illustrated in their monograph, thus suggesting there was more than a single specimen. This was my rationale for designating a lectotype rather than a holotype . I was unable to locate any of the presumed paralectotypes . Gymnetis smaragdinea Gory and Percheron, 1833: 70 , 341 ( New synonymy ). Lectotype female at MHNG, examined. Type locality: “ Brasilia ” on the specimen label but “ Mexique ” in the original description. Gymnetis klugi Gory and Percheron, 1833: 70 , 342 (synonym). Type not seen. Type locality: “Brés. mérid.” (central Brazil ). Cotinis nitidicollis Moser 1907: 144 ( New synonymy ). Holotype male at ZMHU, examined. Type locality: “Brasilia”. Figs. 41–44. Heterocotinis terminata . 41) Habitus; 42) Mesometasternal process, lateral view; 43–44) Parameres. Description. Length 15.7–21.1 mm ; width across humeri 8.8–12.3 mm . Color dorsally and ventrally dark green, weakly shiny, with chalky white, cretaceous marks as follows: head with short, longitudinal band on frons and clypeus either side of middle; pronotum with narrow band on lateral margins mesad of bead; epimera each with narrow band on posterior margin; elytra with slender bands on lateral margins, a short transverse band at about middle next to suture (this band occasionally broken into 2 or 3 spots), a short transverse band behind middle next to lateral margin, and with subapical, transverse band behind and mesad of prominent apical umbones; pygidium with broad band on each lateral margin or nearly covering entire surface except at middle; metasternum and metepisterna each partially covered; metacoxae covered on lateral half; pro- and mesofemora each with band on posterior margin, metafemora each with band on both anterior and posterior margins; abdominal ventrites 2–6 each with broad band nearly covering all of each sternite except at middle. All cretaceous markings may be variably reduced, especially in males. Head : Lateral margins weakly elevated. Clypeus slightly concave either side of median, longitudinal tumescence. Frons and clypeus with moderately large, dense punctures. Clypeus with apex broad, center reflexed upwards and arcuately produced. Eyes small, interocular width 5.0–6.0 transverse eye diameters. Antenna with 10 antennomeres, scape as long as next 4 antennomeres, club distinctly longer than antennomeres 2–7 in both sexes. Pronotum : Surface on disc with moderately large, moderately dense, ocellate punctures, punctures becoming large on sides. Sides with thick marginal bead. Elytra : Surface with 5 longitudinal rows of small, ocellate, C-shaped punctures between suture and humerus; 2 low, discal costae on posterior half, costae coalescing at apical umbone. Apices at suture subacutely produced. Pygidium : Surface in both sexes densely, transversely strigulose in area not covered by cretaceous tomentum, slightly depressed either side of middle on apical half. In lateral view, profile weakly convex. Venter : Setae moderately long. Mesometasternal process broadly rounded, slightly protuberant and parallel to ventral axis of body in lateral view ( Fig. 42 ). Abdominal ventrites nearly smooth on non-cretaceous areas and with small, sparse punctures. Legs : Protibia tridentate in both sexes, basal tooth removed from others. Parameres ( Figs. 43–44 ): Parameres subrectangular in caudal view, apices broadly rounded, each with small angulation or tooth on lateral margin before apex. Distribution. Heterocotinis terminata is known from Brazil . Locality Records. 18 specimens from DEIC , MHNG , and MNHN . BRAZIL (7): PARANÁ (2) : Curitiba, No data. NO DATA (5). NO DATA (11) . Temporal Distribution. All the specimens examined were without temporal data. Diagnosis. Heterocotinis terminata is distinguished from H. semiopaca by the equally shiny pronotum and elytra (shiny pronotum and opaque elytra in H. semiopaca ); a few small punctures behind the apical umbones of the elytra (with dense punctures in H. semiopaca ); a strigulose pygidium (nearly smooth in H. semiopaca ); and slightly protuberant mesometasternum (not protuberant in H. semiopaca ) (compare Figs. 38 and 42 ). The parameres of H. terminata are proportionately longer and with a smaller apicolateral tooth than H. semiopaca (compare Figs. 39–40 and 43–44 ). Nomenclature. After examining the type specimens of Gymnetis smaragdinea Gory and Percheron at MHNG and Cotinis nitidicollis Moser at ZMHU, I concluded that they were conspecific with H. terminata . Burmeister (1842) transferred Gymnetis klugi Gory and Percheron to his newly created Cotinis . Schaum (1844) , noting that G. klugi was unknown to Burmeister, then placed it in junior synonymy with C. terminata Gory and Percheron. Natural History. Nothing is known of the natural history of this species.
