The genus Platynectes (Coleoptera: Dytiscidae: Agabinae) in Central America, with the discovery of the northernmost Neotropical species in Oaxaca, Mexico, and nomenclatural notes on the subgenus Agametrus
Original language description
Platynectes (Agametrus) zoque sp. nov. is described from Oaxaca State, Mexico. It is externally similar to the sole Central American member of the subgenus Agametrus Sharp - P. nitens (Sharp) from Panama and Costa Rica, but can be recognized by the shape of the median lobe of aedeagus. Analysis of the cytochrome oxidase I gene fragment confirmed that the new species is closely related to P. nitens, but undoubtedly different with genetic distance of 6.8% between them. Diagnostic characters of both species are illustrated. The present finding of Platynectes in Mexico extends the known distribution of the genus in the Americas by about 1,300 km to the northwest. Thirteen species of the subgenus Agametrus are currently known, occurring in Cordilleras from Chile to Mexico; a list of all species is provided including ten formal new combinations resulting from the phylogenetic analysis of Toussaint et al. (2017): Platynectes (Agametrus) boliviensis (Régimbart, 1899) comb. nov., P. (A.) humilis (Sharp, 1882) comb. nov., P. (A.) labratus (Sharp, 1882) comb. nov., P. (A.) nitens (Sharp, 1887) comb. nov., P. (A.) peruvianus (Laporte, 1835) comb. nov., P. (A.) rotundatus (Brinck, 1948) comb. nov. (all from Agametrus); P. (A.) curtulus (Régimbart, 1899) comb. nov., P. (A.) darlingtoni (Guéorguiev, 1971) comb. nov., P. (A.) gaudichaudii (Laporte, 1835) comb. nov., and P. (A.) muelleri (Kirsch, 1865) comb. nov. (all from Leuronectes Sharp). Platynectes (Gueorguievtes) darlingtoni Guéorguiev, 1972, a junior homonym of P. (A.) darlingtoni (Guéorguiev, 1971), is replaced with its junior subjective synonym Platynectes multimaculatus Watts, 1978.
