O. nitidicollis is immediately distinguished from all other taxa of the species-group related to O. rutilans (Klug, 1834) , and O. fulgens (Klug, 1834) by the absence of whitish elytral maculae. Moreover, the labrum in O. nitidicollis is metallic-black in both sexes (very rarely in some males with testaceous narrow area at the anterior margin). The immaculate elytra are shared with O. microptera nom. nov. which, however, immediately differs in having its elytra in both sexes conspicuously ovaliform. The adults of O. nitidicollis are strong fliers having normally developed thoracic wings ( Fig. 22 ) as in all other Odontocheila (when the foldable wings are stretched, they are approximately as long as the whole body). In contrast, the flightless O. microptera nom. nov. has uniquely atrophic thoracic wings and its labrum is in male strongly bicoloured, ivoryyellow on more than half of anterior labral area. Female labrum ( Figs 17–18 ) is mostly entirely metallic black, but bicolored labra also occur in both species. Moreover, the elytral apices in O. nitidicollis are generally blunter, less acute towards the sutural spine. The aedeagi in these two species have hooked apex as in O. rutilans , O. fulgens and others of the O. rutilans species-complex, but in most males of O. nitidicollis the ventral edge of the aedeagus apex is straighter and with an indentation. However, the shape varies to the extent that the indentation in the lectotype ( Fig. 25 ) and some other males ( Fig. 26a, 29 ) is so distinct that it may resemble the aedeagus apex of O. trilbyana Thomson, 1857 (as in fig. 8tr by Rivalier 1969 and fig. 131 by Moravec 2015a ), which is otherwise a very different species, while in some other males the aedeagus apex is ventrally almost rounded ( Figs 27–28 ) as in the speciescomplex of O. rutilans , and in most males of O. microptera nom. nov. The male antennal scape ( Figs 20–21 ) is in O. nitidicollis and O. microptera narrower than that in O. rutilans and others of the species-complex, which all have the scape more distinctly dilated (the spatulate-dilated apex in O. rutilans was overlooked by Huber (1999) when he described O. suareziana Huber, 1999 , and the error was adopted by Pearson et al.(1999) who obviously did not examine the holotype of Cicindela rutilans Klug, 1834 in MFNB). The bright coloured, subglobose pronotal disc, as well as the mandibles and palpi, are in O. nitidicollis shaped as in O. fulgens , but the pronotal disc is in O. nitidicollis covered with shallower rugae, the antennal scape is less markedly dilated. Pearson et al. (1999) misleadingly mentioned that O. nitidicollis lacks rugae on its pronotum, but in fact, the wide median area of the pronotal surface is covered with shallow or deep, wide and rather distinct, mostly transverse rugae, which are shallower or effaced only on lateral areas. Redescription . Body ( Figs 1–3 ) medium-sized (of a very variable size independent of sex) 9.30–11.3 (LT 11.0) mm long, 2.90–3.60 (LT 3.30) mm wide, dark coppery except for shiny reddish-cupreous pronotum or also head, with faint green-blue lateral iridescence. Head ( Figs 10–12 ) with notably large eyes, but always at least slightly narrower than body, width 2.90–3.20 mm ; all head portions glabrous. Frons steeply sloped towards clypeus, with distinctly convex median area, dorsally bluntly triangular, deep violaceous-blue with gold-bronze and blue-green lustre on lateral areas and reddish-cupreous in middle, sharply delimited from clypeus and confluent with vertex over bluntly triangular, median frons-vertex fold, but with rather distinct lateral edges reaching orbital margins and thus delimiting the frons from vertex laterally; supraantennal plates flat and with strong metallic-violaceous lustre; frons surface smooth except for the median area of fronsvertex fold ornamented with distinct, vermicular or mostly transverse-wavy rugae forming a distinct ornament passing on anteromedian area of vertex. Vertex with only one juxtaorbital sensory seta (on each side), anteromedian area rather distinctly convex, dark coppery or brighter reddish cupreous in middle delimited with usually iridescent green-blue sublateral areas; fronsvertex fold and anteromedian convex area transversely wavy and arcuate rugulose (sculpture passing from frons), large juxtaorbital areas and lateral areas distinctly and deeply longitudinally parallel-striate, distinct striae on moderately impressed sublateral and lateral areas divergent posteriad, passing on temples, while the posteromedian moderately convex area is notably finely longitudinally striate, passing posteriad to irregularly finely vermicular to asperate sculpture; posterior and occipital area moderately convex, finely irregularly vermicular-rugulose to asperate. Clypeus iridescent reddish cupreous with either narrow or prevailing iridescent green or blue lateral areas, surface usually almost smooth or coriaceous, often with few wrinkles mostly on lateral areas.

Mandibles ( Figs 10–12 ) in male mostly metallic-black (slightly faded to black-brown in old specimens), in female usually almost black, in both sexes with ivory-yellow lateral stripe (much more extended in male) and usually with limited, brownish-testaceous juxtamolar area; normally shaped (lateral margins including terminal teeth arcuate), subsymmetrical, inner teeth rather variable in shape and size: left mandible with second tooth simple, while it is in right mandible notably dilated or variably moderately or distinctly bilobed ( Figs 10–11 , but in LT ( Fig. 10 ) the bilobed part broken); third and fourth teeth in left mandible either gradually smaller towards basal molar, or of almost same length and slightly or more notably smaller than second tooth, while in right mandible the third and fourth teeth are usually much smaller than the second tooth; sometimes, mostly in female, the third tooth is usually somewhat smaller than the fourth. Palpi ( Figs 10–12, 19 ). Maxillary palpi ivory yellow to ochre, terminal palpomeres in male ochre-testaceous with metallic black apical half, in female entirely black and often also penultimate palpomere blackened or black, moderately or more distinctly dilated, in male usually spatulate-dilated ( Fig. 19 ), width 0.20–0.22 mm ; labial palpi ivory-yellow to ochre-testaceous except for black terminal palpomeres; penultimate (longest) palpomeres rather wide, cylindrical, only gradually dilated towards apex.

Thorax. Pronotum ( Figs 23–24 ) rather variably coloured, shiny metallic reddish-cupreous or golden-cupreous, with narrow or prevailing iridescent green lateral areas, but also blackened on disc in middle or on its lateral areas, as long as wide or very slightly longer, length 1.90–2.30 mm , width 1.85–2.25 mm ; sulci clearly pronounced (anterior sulcus deep only laterally, posterior sulcus deeper); anterior lobe distinctly wider than the posterior, but narrower than dorsally visible proepisternal margins, its anterior margin in middle often notably prolonged anteriad, mostly reddish-cupreous with green lateral margins, very irregularly and mostly very shallowly wrinkled; disc almost subglobose, notopleural sutures indistinct, running parallel with the convex lateral margins; median line distinct; discal surface covered with shallow, but wide and distinct, irregular or mostly transverse rugae which are coarser on median area and become shallower and effaced on lateral areas; prosternum, mesosternum and metasternum smooth and glabrous, metallic black, usually with faint or strong greenish, cobalt-blue, or violaceous lustre; proepisterna and mesepisterna smooth and glabrous, shiny metallic black, usually with diffusing metallic lustre; female mesepisternal coupling sulci indistinct, with only sinuous, longitudinal median furrow, only slightly deeper and sharper in dorsal area than in male; metepisterna shiny metallic black, finely wrinkled.

Aedeagus ( Figs 25–29 ) shaped as in most other species of the genus, moderately voluminous in middle, 3.00– 3.50 mm long, 0.80–0.95 mm wide, with variably shaped apex which is hooked, but its ventral edge is mostly nearly straight and with an indentation forming almost a “hammer-like” apex ( Figs 25–26a ), or the ventral edge is ventrally rounded forming almost simply hooked apex ( Figs 27–28 ); in its ventral view ( Fig. 26b ) the apex appears with the ventral edge running centrally upwards, then clavate-dilated, and the very apex terminated by a rounded knob; internal sac ( Fig. 29 ) as in most other species of the genus with long convoluted flagellum of which the flagelliform part usually protrudes from the dorsoapical orifice and its voluminous base is large and normally shaped with arcuate dorsal margin as in others of the species-group related to O. rutilans . Variability . As emphasized in the “Differential diagnosis” and partly also in the “Redescription” above, the most important variability is in the shape of the aedeagus apex, occurring also in syntopic males. Biology and distribution . O. nitidicollis has a large distribution. It is known from Venezuela where it was recently caught in the Canaima National Park in the district of Bolivar , and it spreads to the central-western Brazilian state of Mato Grosso . It also spreads to the Brazilian Highlands in the province of Goyas , all characterized by diverse ecosystems, including the cerrado vegetation of savannah, but also penetrating to Amazonas (found in the area of Rio Solimões, one of the largest Amazon tributaries), towards Obidos on the northeastern coastal areas of the state of Pará . It also occurs in the south-eastern states of Sao Paulo and Minas Gerais , and in the north-eastern states of Bahia and Pernambuco . Mandl (1960) reported it from the northern Brazilian state of Acre on the border of Bolivia . It is rather common in Bolivia ; apart from the examined specimens caught mostly by the third author and listed above, other records from the districts of Beni and Santa Cruz were published by Pearson et al. (1999) . O. nitidicollis is obviously much rarer in Paraguay as only one exact record from Paraguay was published by Wiesner (2000) based on one female (JWCW, see above) caught in Villarica, and he also cited the record from Mborero (province of Guairá ) published by Schade (1933) . Two recent records from Paraguay are the male caught by the first author in the Estancia Terrado in the department of Conception (CCJM), and the three males caught by the third author near Barrio San Pedro (DBCN). Regarding the occurrence in Argentina , Wiesner & Bandinelli (2014) only refer to general records in literature ( Salta , Tucuman by Bruch 1911 , Jujuy and Formosa by Erwin & Pearson 2008 ), without any exact or recent record. Two specimens (males) were labelled as if from French Guiana : one syntype ( paralectotype here) with the large, additionally attached collection label: “ nitidicollis / Dej. / Cayenne / C. Gory”, and one other specimen (both listed above) labelled: “ Guyane Fr.” and with ambiguous “Passaura”. Within this revision, no other specimen of O. nitidicollis from French Guiana was found in collections, but because this species radiates from Venezuela to Brazil , its occurrence in French Guiana is possible. Most of the old specimens listed in the “Other material examined”, as well as records in literature, do not specify the biotopes of O. nitidicollis . According to Pearson et al. (1999) and Erwin & Pearson (2008) who listed a great number of Bolivian localities (most of them examined here), and experience gained by the third author, this species is ecologically distinctive as it inhabits dry uplands and scrubby grasslands, at nights also attracted to lights, but it also occurs on edges of secondary forests, together with Odontocheila chrysis (Fabricius, 1801) . The area of Pernambuco , Bonito comprises remaining Atlantic Rainforest and the Caatinga biome (xeric shrubland and thorn forest) in the north-eastern Brazilian State of Pernambuco (André Silva Roza pers. com.). As discussed by Roza and Mermudes (2015) , the Atlantic Rainforest is one of the most threatened biomes of the world, with only 11−12 % of its original cover. The Mato Grosso area of Barra do Carcas is in the State Park of Serra Azul with predominant Cerrado biome. In Bolivia , O. nitidicollis sometimes was found by the third author together with Pentacomia ( Mesochila ) discrepans (W. Horn, 1893) , P. ( Poecilochila ) cupricollis (Kollar, 1836) and P. ( Poecilochila ) rugipennis (Kollar, 1836) ; in the department of Santa Cruz it is sympatric, but probably not syntopic with Odontocheila camuramandibula Huber, 1999 , which mostly inhabits different biotopes. The males from the Paraguayan Estancia Terrado ( CCJM ) and Barrio San Pedro ( DBCN ) were caught on bare soil of the grassy cattlepastures with termite mounds. Remarks . Only the male sex of Cicindela nitidicollis was described by Dejean (1825) , but he did not mention the number of the males. Besides the male designated here as the lectotype to increase stability of the taxon, two other males, also originally from the Dejean-Chaudoir collection (MNHN), are obviously syntypes , therefore considered paralectotypes here, although one of them bears the large, originally a common collection label with “Cayenne” (see “ Type material” above), obviously written in error. The collecting label was attached to this syntype subsequently when the specimens were moved from the historical Dejean-Chaudoir collection, and arranged in the box of the MNHN “Collection Géneralle” (together with the syntype designated here as the lectotype ). It must be noted here that when Rivalier arranged the specimens in MNHN, he, as in many of other taxa, had not recognized most of the type specimens by Dejean, because old authors mostly did not label their types by a “ type ” label. The name “ Cicindela Auricollis ” was mentioned by Dejean (1825) as a synonym of his O. nitidicollis . Dejean simultaneously cited Germar as if he attributed the name “ auricollis ” to him, but Germar never mentioned the name. Notwithstanding, C. auricollis is a nomen nudum, listed without a description also by Sturm (1826) and as a “synonym” of O. nitidicollis by Sturm (1843) and Fleutiaux (1892) . Sherborne (1928) attributed the unavailable name (as nomen nudum ) to Sturm (1826) .
