Contribution to the knowledge of the family Nemonychidae (Coleoptera) with descriptions of new taxa

Abstract

<p>Two new tribes, the Zimmiellini Legalov, trib. n. (type genus: <em>Zimmiellus</em> Kuschel, 2011), which differs from the tribe Rhinorhynchini by the mandible exodontous, maxillary palpi barely extending forward beyond the prementum and position of rostrum base, and the Argentinomacerini Legalov, trib. n. (type genus: <em>Argentinomacer</em> Legalov, gen. n.) that differs from the tribe Rhynchitomacerini by having the pronotum narrowed before the basal fourth, antennae inserted subbasally and club 4-articled. Also erected is a new subtribe Bunyaeina Legalov, subtrib. n. (type genus: <em>Bunyaeus</em> Kuschel, 1994) that differs from the subtribe Mecomacerina by procoxae hemispherical, mesonotum with one coarsely ridged stridulatory file and forehead distinctly wider than apex of rostrum. Two new genera, <em>Nothofagomacer</em> Legalov, gen. n. (type species: <em>Rhynchitomacer</em> <em>apionoides</em> Kuschel, 1959) that differs from the genus <em>Rhynchitomacer</em> by the mandibular sockets not being visible in dorsal view, elytral striae regular, postmentum deeply emarginate and vaginal vestiture absent; and <em>Argentinomacer unicus</em> Legalov, gen. et sp. n. from Argentina, are described. A key to subfamilies, tribes, subtribes, genera and subgenera of Recent Nemonychidae with a list of species is provided. The distribution of some Palaearctic species is specified.</p>
