Morphology, phylogeny and classification of adult Endomychidae (Coleoptera: Cucujoidea)

— The cucujoid family Endomychidae is characterized. Detailed morphology of 36 exemplar genera representing 12 recently recognized subfamilies is presented. Cladistic analy­ sis was accomplished based on 50 taxa (47 genera from Endomychidae and Coccinellidae the ingroup, and 3 genera from Helotidae, Brachypteridae and Protocucujidae the outgroups) coded for 40 adult, morphological characters. Based on the analysis, a phylogeny of the family is hypothesized. Results of the analysis suggest that the Endomychidae form a monophyletic taxon, which maybe divided into 12 subfamilies: Danascelinae (subfam. nov.), Xenomycetinae, Endomychinae, Anamorphinae, Merophysiinae, Lycoperdininae, Stenotarsinae, Epipocinae, Eupsilobiinae, Pleganophorinae, Mycetaeinae and Leiestinae. Short diagnoses for the family and subfamilies, as well as a key to the subfamilies are provided. The following two new, sub­ family synonyms are proposed: Anamorphinae Strohecker, 1953 (=Acritosomatinae Pakaluk and Ślipiński, 1995) and Merophysiinae Seidlitz, 1872 (=Holoparamecinae Seidlitz, 1888). Adamia gen. nov. (type species: A. mexicana sp. nov.) and Erotendomychus lawreneei sp. nov., are described. Type species are designated for the following genera: Niteta Weise, 1890 {N. quatuordecimpunctata Weise, 1890), Oediarthrus Gerstaecker, 1858 ((). natalensis Gerstaecker, 1858) and Stenotarsoides Csiki, 1900 (S. quadrimaculatus Csiki, 1900). History of classification and known facts concerning the biology of the family are provided.
