Holotype ♂ and allotype ♀ in CMNC (not examined). Paratypes. Of the 41 typespecimens listed by  Johnson(1996), following paratypesexamined: 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]. 1 ♀ in NHMW with same labels except for: “ 21– 24.V.1994, B. D. Gill”.   Differential diagnosis.  O. tawahkahas 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. iodopleuraby 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. tawahkanotably paler. For the differences of  O. mexicanaand  O. potosiana  sp. nov.see under  O. iodopleura.   O. ignitaand  O. exiliscan 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 122) 8.80–9.90 mmlong, 2.60–3.00 mm wide. Head ( Fig. 123) 2.65–2.90 mmwide, all head portions basically as in  O. iodopleura. Labrum basically shaped as in  O. iodopleura, but generally paler; male labrum ( Figs 124–125) 0.70–0.75 mmlong, 1.05–1.15 mmwide; female labrum ( Fig. 126) 1.10 mmlong, 1.15 mmwide. Palpi ( Fig. 123) as in  O. iodopleura, but generally paler. Mandibles ( Fig. 123) as in  O. iodopleura, but notably paler. Antennae ( Figs 121, 123) rather short, in male reaching only elytral third, scape with only apical seta, together with antennomeres 2–4 metallic ( Fig. 123) blue or violaceous, antennomeres 5–11 smoky black. Pronotum ( Fig. 127) 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 129–131) shaped as in  O. iodopleura, 5.30–5.80 mmlong, 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. 128) as in  O. iodopleuraand other species of this species-complex, 3.20 mmlong, 0.85 mmwide.  Variability. The examined paratypesof  O. tawahkapossessed only indistinct variability.   Biology and distribution(map Fig. 208).  Odontocheila tawahkais known only from the typeseries 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 Tawahkapeople. 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. ignitaand  O. exilisas its closest relatives, despite the very different shape of the apex of their aedeagi; in fact,  O. tawahkais morphologically similar to  O. iodopleura(see under that species above). 1434647477 [151,879,649,671] Honduras 15.05 Krausirpi 1286 -84.86667 29 480 1 Gracias a Dios holotype 1434647465 Johnson 29 480 41 paratype 1434647460 1994-05-23 RLHC RD Cave Collector Honduras 15.05 Krausirpi 1286 -84.86667 29 480 1 1 Gracias a Dios paratype
