A review of the genus Platynectes from the Solomon Islands (Coleoptera: Dytiscidae: Agabinae)

Seven new species of the genus Platynectes Régimbart, 1879 from Solomon Islands are described: barana sp. nov., P. mbaole popomanaseu nov. (all Guadalcanal), lunga (Guadalcanal and Savo), malaita (Malaita), makira (Makira) owaraha (Makira Owaraha). insularis J. Balfour-Browne, 1939, described Vanuatu Solomons, currently considered a junior subjective synonym semperi 1899, is reinstituted as valid based on its morphology molecular analysis by Toussaint et al. (2017). The paratypes Solomons shown to belong – and, thus, distribution restricted Vanuatu. Habitus male genitalia illustrated for all seven insularis. A checklist Dytiscidae so far recorded appended.
