          Abstract

          Forty-nine new species of Neotropical Exosternini are described in this work, representing the newly recognized Phelister blairi species group, within the large, heterogeneous taxon Phelister . Eight previously described species are also assigned to this group. Relationships within are indicated with several informal subgroups: P. blairi subgroup: ( P. blairi Hinton, 1935, P. erwini sp. nov., P. fimbriatus sp. nov., P. stellans sp. nov., P. sparsus sp. nov., P. pretiosus sp. nov., P. trigonisternus Marseul, 1889, P. globosus sp. nov., P. serratus sp. nov., P. geminus sp. nov., P. parana sp. nov., P. asperatus sp. nov., P. uniformis sp. nov., P. miscellus sp. nov., P. inbio sp. nov., P. sculpturatus Schmidt, 1893, P. tunki sp. nov., P. praedatoris Reichensperger, 1939, P. ifficus sp. nov., P. genieri sp. nov., P. marginatus sp. nov., P. vazdemelloi sp. nov., P. dilatatus sp. nov., P. spectabilis sp. nov., P. pervagatus sp. nov.); P. amazoniae subgroup: ( P. morbidus sp. nov., P. annulatus sp. nov., P. sphaericus sp. nov., P. geijskesi Kanaar, 1997, P. fraternus sp. nov., P. conjunctus sp. nov., P. chabooae sp. nov., P. striatinotum Wenzel & Dybas, 1941, P. notandus Schmidt, 1893, P. amazoniae (Lewis, 1898) comb. nov., P. arcuatus sp. nov.); P. gregarius subgroup: ( P. gregarius sp. nov., P. praecisus sp. nov., P. rudis sp. nov., P. incongruens sp. nov., P. congruens sp. nov., P. praesignis sp. nov.); P. umens subgroup: ( P. umens sp. nov., P. almeidae sp. nov., P. chicomendesi sp. nov., P. microdens sp. nov., P. matatlantica sp. nov.); P. curvipes subgroup: ( P. curvipes sp. nov., P. vilavelha sp. nov.); P. rio subgroup: ( P. rio sp. nov., P. semotus sp. nov., P. uncinatus sp. nov., P. inscriptus sp. nov.); incertae sedis – unplaced to subgroup: ( P. incertus sp. nov., P. okeefei sp. nov., P. blairoides sp. nov., P. pirana sp. nov.). Lectotypes are designated for the following species: P. trigonisternus Marseul, P. sculpturatus Schmidt, P. praedatoris Reichensperger, P. notandus Schmidt, and Discoscelis amazoniae Lewis. Preliminary phylogenetic analyses of the broader Neotropical Exosternini do not support the monophyly of the P. blairi group, nor of all of these subgroups, but the majority do fall within one large clade (which is potentially paraphyletic with respect to some other Neotropical exosternine genera). More work on the phylogeny and taxonomy of this diverse fauna is needed.

          A systematic revision of Operclipygus Marseul (Coleoptera, Histeridae, Exosternini)

          Abstract We revise the large Neotropical genus Operclipygus Marseul, in the histerid tribe Exosternini (Histeridae: Histerinae). We synonymize 3 species, move 14 species from other genera, sink the genus Tribalister Horn into Operclipygus , and describe 138 species as new, bringing the total to 177 species of Operclipygus . Keys are provided for the identification of all species, and the majority of the species are illustrated by habitus and male genitalia illustrations. The species are diverse throughout tropical South and Central America, with only a few species extending into the temperate parts of North America. The majority of species can be recognized by the presence of a distinct stria or sulcus along the apical margin of the pygidium, though it is not exclusive to the genus. Natural history details for species of Operclipygus are scant, as most specimens have been collected through the use of passive flight interception traps. Many are probably generally associated with decaying vegetation and leaf litter, where they prey on small arthropods. But a small proportion are known inquilines, with social insects such as ants and termites, and also with some burrowing mammals, such as Ctenomys Blainville. The genus now includes the following species groups and species: Operclipygus sulcistrius group [ Operclipygus lucanoides sp. n., Operclipygus schmidti sp. n., Operclipygus simplistrius sp. n.,
