Morphogenia: a new genus of the Neotropical tribe Jubini (Coleoptera,Staphylinidae, Pselaphinae) from the Brazilian Amazon

A new genus and species of the large Neotropical pselaphine tribe Jubini is described from Manaus, Brazil, based on material preserved in the Natural History Museum, London. Morphogenia struhligen. et sp. n. represents the possible sister taxon of the abundant and speciose genus Barrojuba Park, sharing with it the putatively derived condition of anterolaterally shifted vertexal foveae, producing a smoothly convex vertex devoid of fovea or sulci. However, unlike Barrojuba, Morphogenia retains a plesiomorphic antebasal sulcus on the pronotum in both sexes, and additionally lacks elaborate abdominal fovea-like pockets and teeth on the lateral margins of the pronotum that are typical of Barrojuba. The genus is also unusual among jubine genera in lacking the characteristic V- or Y-shaped gular carina. In contrast to the commonly-collected Barrojuba, specimens of Morphogenia are absent in extensive jubine collections housed in museums in the United States, indicating that the new taxon may be relatively scarce or localised.

Weiria australis gen. n., sp. n., the first fully myrmecoid aleocharine staphylinid from Australia (Coleoptera: Staphylinidae: Aleocharinae: Aenictoteratini)

Abstract Weiria australis gen. n and sp. n. (type locality Western Australia, Kimberley Region, CALM Site 25/1, Synnot Ck.), a myrmecoid (ant-like body form) aleocharine staphylinid, is described, and habitus and line illustrations are provided for its recognition. The species is tentatively placed in the tribe Aenictoteratini; similarities and differences to tribal characters shared by other members of the Aenictoteratini, and similarities and differences to other aenictoteratine genera are discussed. This is the first fully myrmecoid aleocharine, and the first member of the tribe Aenictoteratini, known from Australia. Association of Weiria gen. n. with the ant genus Aenictus Shuckard is postulated.
