Odontocheila tawahka Johnson, 1996 

( Figs 122–131View FIGURES 122 – 131, 208View FIGURE 208).

Odontocheila tawahka Johnson, 1996: 38  , 39, fig. 1, 40.

Type locality. Honduras: Krausirpi , Gracias a Dios, 15°03´N, 84°52´W.GoogleMaps 

Type material. Holotype ♂ and allotype ♀ in CMNC (not examined). Paratypes. Of the 41 type specimens listed by Johnson (1996), following paratypes examined  : 1 ♂ in FCCR, 2 ♂♂ in DBCN, 1 ♂, 1 ♀ in RLHC: “ Honduras, Krausirpi , Gracias a Dios, 15°03´N, 84°52´W, 23 May 1994, RD Cave Collector ”[printed]; “ Paratype, Odontocheila tawahka, W. Johhnson  ” [yellow, printed]GoogleMaps  . 1 ♀ in NHMW with same labels except for: “ 21– 24.V.1994, B. D. Gill”.

Differential diagnosis. O. tawahka  has the apex of its aedeagus very similar to the aedeagi of O. mexicana  , O. potosiana  sp. nov. and O. iodopleura  .

It can be distinguished from the closely related O. iodopleura  by its almost uniformly bright green or violaceous-blue elytra (except for the purple-violet juxtaepipleural stripe usual in all species). Moreover, the labrum and particularly the mandibles, penultimate and terminal palpomeres of maxillary palpi and legs are in O. tawahka  notably paler.

For the differences of O. mexicana  and O. potosiana  sp. nov. see under O. iodopleura  .

O. ignita  and O. exilis  can be immediately distinguished by their predominantly reddish-cupreous elytra and very different aedeagi.

Redescription (based on the examined paratypes, and with comparison to O. iodopleura  ).

Body ( Fig 122View FIGURES 122 – 131) 8.80–9.90 mm long, 2.60–3.00 mm wide.

Head ( Fig. 123View FIGURES 122 – 131) 2.65–2.90 mm wide, all head portions basically as in O. iodopleura  .

Labrum basically shaped as in O. iodopleura  , but generally paler; male labrum ( Figs 124–125View FIGURES 122 – 131) 0.70–0.75 mm long, 1.05–1.15 mm wide; female labrum ( Fig. 126View FIGURES 122 – 131) 1.10 mm long, 1.15 mm wide.

Palpi ( Fig. 123View FIGURES 122 – 131) as in O. iodopleura  , but generally paler.

Mandibles ( Fig. 123View FIGURES 122 – 131) as in O. iodopleura  , but notably paler.

Antennae ( Figs 121View FIGURES 108 – 121, 123View FIGURES 122 – 131) rather short, in male reaching only elytral third, scape with only apical seta, together with antennomeres 2–4 metallic ( Fig. 123View FIGURES 122 – 131) blue or violaceous, antennomeres 5–11 smoky black.

Pronotum ( Fig. 127View FIGURES 122 – 131) shaped and with surface sculpture as in O. iodopleura  , metallic-green with blue or violaceous lateral areas, mostly as long as wide, length 1.75–1.85 mm, width 1.80–1.85 mm.

Elytra ( Figs 129–131View FIGURES 122 – 131) shaped as in O. iodopleura  , 5.30–5.80 mm long, almost uniformly coloured (except for the common, violaceous juxtaepipleural area), metallic-green or green-blue, sometimes with extended purpleviolaceous lateral area, pattern of punctation and whitish elytral maculae as in O. iodopleura  .

Legs as in O. iodopleura  , but notably paler.

Aedeagus ( Fig. 128View FIGURES 122 – 131) as in O. iodopleura  and other species of this species-complex, 3.20 mm long, 0.85 mm wide.

Variability. The examined paratypes of O. tawahka  possessed only indistinct variability.

Biology and distribution (map Fig. 208View FIGURE 208). Odontocheila tawahka  is known only from the type series caught in Honduras. The village of Krausirpi lies on the banks of the Patuca River in the municipality of Wampusirpi, department of Gracias a Dios, a centre of indigenous Tawahka  people. According to Johnson (1996), the adults were caught along a trail within relatively undisturbed tropical forest.

Remarks. In the original description of O. tawahka, Johnson (1996)  did not describe aedeagus of his new species, and probably for that reason he considered O. ignita  and O. exilis  as its closest relatives, despite the very different shape of the apex of their aedeagi; in fact, O. tawahka  is morphologically similar to O. iodopleura  (see under that species above).
