Differential diagnosis. O. ignita  possesses similar, dense elytral sculpture of commonly anastomosing punctures as in O. iodopleura  , O. tawahka  and O. exilis  . However, males of O. ignita  immediately differ in having much wider, capitate apex of their aedeagi, in contrast to much narrower apex of the aedeagi in O. iodopleura  and O. tawahka  (and also in O. mexicana  and O. potosiana  sp. nov.); the male labrum in O. ignita  is mostly notably shorter than in males of O. iodopleura  and O. tawahka  ; females of O. ignita  can be distinguished from O. iodopleura  and O. tawahka  by their narrower pronotal disc with bright reddish sublateral areas, and more irregular and finer surface sculpture (in contrast to the pronotal disc in O. iodopleura  and O. tawahka  , which is much wider and covered with generally coarser and more regular and continuous rugae, particularly along the median line). Nevertheless, very rarely adults of O. ignita  possess wider pronotal disc and such females may cause a confusion with females of O. iodopleura  which, apart from the above mentioned difference in the surface sculpture of the pronotal disc, differ in having more distinctly multicoloured elytra.

O. exilis  is externally very similar, but can be distinguished from O. ignita  by generally larger size, generally smaller white elytral maculae, and almost subacute elytral apices in both sexes. In addition, females of O. exilis  have much darker mandibles and legs, and usually even denser elytral punctation of which the narrow intervals form almost reticulate ornamentation on the elytral disc. Males of O. exilis  are clearly recognizable by the differently shaped apex of their aedeagi ( Figs 197–207View FIGURES 193 – 207), in contrast to the capitate apex of the aedeagi in O. ignita  ( Figs 161–176View FIGURES 158 – 176); moreover, the labrum in O. exilis  is slightly but notably longer.

O. potosiana  sp. nov., apart from the very different, much narrower apex of the aedeagus, clearly differs from O. ignita  in having much more regular elytral punctation and an even much finer surface sculpture on its pronotal disc which is, moreover, bright reddish-cupreous in the middle.

O. mexicana  immediately differs in having its pronotal disc notably subglobose and almost smooth and polished.

Redescription. Body ( Figs 132–133View FIGURES 132 – 140, 141–142View FIGURES 141 – 148) medium-sized, 8.80–10.2 (LT 9.70) mm long, 2.70–3.20 (LT 2.80) mm wide, females mostly larger than males.

Head ( Figs 134View FIGURES 132 – 140, 143–144View FIGURES 141 – 148) with notably pronounced eyes, large, as wide as body or slightly smaller, 2.60–3.05 mm wide, all head portions glabrous.

Frons, vertex and clypeus basically as in O. iodopleura  with the same pattern of the striae and rugae on the surface of vertex, but vertex moderately convex in middle, and the striae and rugae somewhat coarser and deeper, and the lateral edges above the supraantennal plates very short and indistinct as formed by much smaller impression at the apices of the supraantennal plates.

Genae as in O. mexicana  , but mostly shallowly parallel-striate also on median and anterior area.

Labrum 4-setose; distinctly bicoloured; male labrum ( Figs 135–137View FIGURES 132 – 140, 145–146View FIGURES 141 – 148) with shape of teeth basically as in O. mexicana  (anterior margin either shallowly emarginate in middle, or with either indicated or small median tooth), rather short, length 0.60–0.65 mm, width 1.10–1.15 mm, female labrum ( Figs 138–139View FIGURES 132 – 140, 147View FIGURES 141 – 148) 1.00– 1.15 mm long, 1.15–1.30 mm wide, with prominent, acutely tridentate median lobe with protruding median tooth.

Mandibles ( Figs 134View FIGURES 132 – 140, 143–144View FIGURES 141 – 148) metallic-black (faded to brown in old specimens), with distinct, ivory-yellow lateral stripe (more extended in male), normally shaped (as in O. mexicana  ).

Palpi ( Figs 134View FIGURES 132 – 140, 143–144View FIGURES 141 – 148) shaped as in O. mexicana  , ivory-yellow to ochre-testaceous, terminal palpomeres in both labial and maxillary palpi metallic black; penultimate palpomeres of maxillary palpi variably yellow-ochre to brownish-darkened, or black.

Antennae ( Figs 132–134View FIGURES 132 – 140, 141–144View FIGURES 141 – 148) rather short, in male slightly reaching elytral half, in female shorter, barely reaching elytral third; scape with only apical seta, coloration of scape and antennomeres 2–4 ( Figs 134View FIGURES 132 – 140, 143–144View FIGURES 141 – 148) as in O. iodopleura  .

Thorax. Pronotum ( Figs 157–160View FIGURES 149 – 157View FIGURES 158 – 176) glabrous, usually metallic green-blue in middle, iridescent reddish-cupreous on sublateral areas and iridescent blue-green on lateral areas, slightly but mostly notably longer than wide, length 1.75–2.05 mm, width 1.75–1.95 mm; sulci well pronounced; anterior lobe slightly wider than posterior lobe; surface of anterior lobe rather coarsely, irregularly but mostly transversely rugulose; disc normally shaped with only moderately convex lateral margins of dorsally visible proepisterna, while thin, clearly dorsally visible notopleural sutures are much narrower and mutually subparallel; medial line distinct; whole discal surface up to the notopleural sutures covered with rather fine, wavy to vermicular rugae which are irregularly arranged and only slightly more transverse and coarser on median area; posterior lobe with distinct basal rim, shiny metallic reddishcupreous and mostly iridescent green on distinct dorsolateral bulges, its surface mostly coarsely and irregularly rugulose; all ventral and lateral sterna glabrous; proepisterna, mesepisterna and metepisterna shiny metallic black, rarely with diffusing golden or bluish lustre, female mesepisternal coupling sulci in form of a deep, sinuous longitudinal furrow running in the middle throughout the mesepisternum, more distinctly carved than the similar but shallower furrow in male, lacking any pit; prosternum, mesosternum and metasternum smooth and polished, metallic black with strong, chatoyant, blue or blue-green lustre.

Elytra ( Figs 149–156View FIGURES 149 – 157) elongate, length 5.70–6.70 mm, in male with rounded humeri which are subquadrate in female; lateral margins as in O. mexicana  and other species of this species-complex; dorsal elytral surface and pattern of commonly anastomosing punctures as in O. iodopleura  , but the punctation and also cristulate sculpture on elytral disc is somewhat denser; elytral coloration almost uniformly dark or bright reddish cupreous on elytral disc and also sublateral areas, with narrow or more distinct, blue-green lateral stripe passing to violaceous or purple-violet juxtaepipleural area; whitish elytral maculation in both sexes as in O. iodopleura  .

Abdomen as in other species of this species complex, but ventrites predominantly metallic-blue.

Legs as in O. mexicana  , but metatrochanters in some females blackened; femora rather variably coloured independent of sex, sometimes darker, particularly metafemora almost black (faded in old specimens).

Aedeagus ( Figs 161–176View FIGURES 158 – 176) slightly more voluminous in middle than in preceding species, 3.25–3.40 mm long, 0.95–1.00 mm wide, apex conspicuously capitate; internal sac ( Figs 162, 168View FIGURES 158 – 176) as in the preceding species.

Variability. Apart from some faint differences in the brightness of the elytral coloration, O. ignita  is not significantly variable in its external characters, but in some adults (independent of locality) the pronotal disc is wider than usual and such females my cause confusion with O. iodopleura  (see “Differential diagnosis” above). Humeral macula of female elytra is either reduced and invisible from above, or entirely missing. The aedeagi are somewhat variable in the shape of the capitate apex ( Figs 161–176View FIGURES 158 – 176), but among the great number of examined specimens, only one aedeagus of O. ignita  ( Fig. 172View FIGURES 158 – 176) and one of O. exilis  ( Fig. 203View FIGURES 193 – 207) with the apex of an intermediate shape between these two species have been found.

Biology and distribution (map Fig. 208View FIGURE 208). The occurrence of O. ignita  has been verified only from Mexico (the state of Chiapas) and neighbouring Guatemala, and the occurrence in El Salvador, mentioned by Boyd (1982), has also been confirmed (two specimens in WJCM). Rivalier (1969) quite mistakenly mentioned “Venezuela and Panama” as the only occurrence for O. ignita  , partly because he obviously confused this species with O. exilis  , which was entirely unknown to him as he omitted the name in his review (see under that taxon below). Moreover, one historical specimen in MNHN from the Chaudoir collection bears handwritten labels “Venezuela” and “1543 / Rivalier”; the latter refers to the aedeagus separately mounted by Rivalier between two, underlying and cover glasses (stored in MNHN as “lames”). Examinations of the male and the “lame” with its aedeagus by the first author has confirmed that the male is conspecific with O. ignita  , but the specimen was obviously mislabelled as the occurrence in Venezuela is quite improbable (see “Map of the occurrence Fig. 208View FIGURE 208).

Erwin & Pearson (2008) in error have not mentioned the occurrence of O. ignita  in Mexico, although the country is the type locality of this species.

The records from other countries outside of Mexico and Guatemala by some other authors, such as from Venezuela by Fleutiaux (1892) and Horn (1910, 1926), Panama by Boyd (1982), Costa Rica, Panama and Venezuela by Cassola & Pearson (2001), partly adopted by Erwin & Pearson (2008), are based either on the mentioned mislabelled historical specimens or on the confusion with O. exilis  which occurs in Panama but was not confirmed within this revision from Colombia nor Venezuela. These localities are with question marks in Erwin & Pearson (2008).

Probably influenced by Rivalier (1969), Werner (1993) also erroneously included Panama and Venezuela as the occurrence of O. ignita  , and published ( Werner 1993: 24, plate 12, fig. 89) a colour photograph of a supposed specimen of O. ignita  from Quepos (misspelled by him as “Quopos”) in the Costa Rican province of Puntarenas; thus he obviously confused this species with O. exilis  which occurs in the nearby Manuel Antonio National Park.

The record of O. ignita  from Peru by ( Pearson 1984) was based on misidentification as later rectified by Pearson et al. (1999) that the Peruvian record belonged to “ Pentacomia pentacomioides ( W. Horn, 1900)  ”, which was restored by Moravec (2014) to its original name combination Odontocheila pentacomioides W. Horn, 1900  .

The Mexican region of Soconusco is a narrow strip wedged between the Siera Madre de Chiapas mountains (Cordillera Central) and the Pacific Ocean, along the border with Guatemala in the southwest corner of the Mexican state of Chiapas  . Mapastepek is in the same area and Union Juarez is situated eastwards, just near the border with Guatemala. Quezaltenango lies in south-western Guatemala, while El Zapote (the type locality of the synonymous O. cinctula  ) is situated in north-eastern Guatemala near the border with Belize  .

Like most of Odontocheila  species, adults of O. ignita  inhabits trails through forests, but prefer the open areas for hunting. They frequently fly ahead and land on trails, sometimes landing on low vegetation, and often fly off the trail into the forest, but usually return to more open areas. The adults recently caught by the second author in Quezaltenango, Guatemala, inhabited trails through coffee plantations.

Remarks. Examinations of the type specimens has confirmed the synonymy of O. cinctula Bates, 1881  with O. ignita  by Horn (1904), also treated it as such by Horn (1905, 1910, 1926) and subsequent authors such as Boyd (1982), Wiesner (1992) and Erwin & Pearson (2008), tentatively also by Huber et al. (2006). Lorenz (1989a, b, 2005a, b), Johnson (1996) and Cassola & Pearson (2001) mentioned or listed O. cinctula  as a separate species.

Fleutiaux (1892) treated O. cinctula  as a synonym of Odontocheila secedens Steinheil, 1875  that was described, however, from an area of the town of Muzo in the historical Nueva Grenada, 104 km north of Bogota, Colombia. The synonymy by Fleutiaux (1892) was probably based on specimens labelled “ O. secedens  ”, but those in BMNH with “ secedens  ” on their labels, have their locality label: “Zapote, Guatemala” which is the type locality of the synonymous O. cinctula  , and indeed, these specimens proved to be identical with O. ignita  . In contrast, O. secedens Steinheil  was correctly synonymized with O. salvini  by Horn (1892), and also was treated as the synonym of O. salvini  by Horn (1904), Boyd (1982) and Erwin & Pearson (2008). The synonymy is in accordance with some other specimens in collections labelled as O. secedens  , including the historical ones standing in MNHN (Fleutiaux historical Collection) under this name, and which proved to be conspecific with O. salvini  .

The nomenclature is even more complicated by O. secedens sensu Lynch Arribálzaga (1878)  , which is conspecific with Odontocheila chrysis (Fabricius, 1801)  . Lynch Arribálzaga only misidentified and redescribed the species described by Steinheil (1875), but did not describe a new homonymous species as probably considered by Horn (1905) when he “synonymized” O. secedens sensu Lynch Arribálzaga (1878)  with O. chrysis  .

In addition, Odontocheila iodopleuroides Mandl, 1972  was excluded from the genus Odontocheila (Moravec 2013)  because examination of the holotype (by monotypy) in NHMW by the first author, revealed that this species is conspecific with East Asian Prothyma heteromala MacLeay, 1825  .
