Ordo: Coleoptera
Familia: Dytiscidae
Name
Copelatus sp. 1 – Wikispecies link – Pensoft Profile
Material examined
Guadalcanal: 1 ♀, 0.5 km N Mbaole, 09°37.69'S, 160°06.69'E, 2799 feet, 2007, K. Mailautoka leg. (ZSMG).
Diagnosis
Medium sized (TL: 6.3 mm), elongate, oblong-oval species. Head testaceous, with dark band posterior to eyes; pronotum brown blackish, with testaceous sides; elytra brown blackish, with broad transverse testaceous basal band and testaceous apical part. Pronotum with short longitudinal strioles laterally. Elytra with ten discal striae and a submarginal stria: striae 1, 3, 5, 7, 9, and 10 almost complete and well impressed; striae 2, 4, 6, and 8 present only as a series of short strioles between odd striae; submarginal stria short, split to several strioles on one side (Fig. 13).
Comments to classification
Based on presence of ten discal and a submarginal stria on elytra, the species can be included in the C. erichsonii species group. It could not be associated with any species currently known from the Solomon Islands. Without a male available for the study, we leave this taxon unidentified to species level.
Distribution
The species is known only from a single medium altitude locality in north-central Guadalcanal.
