A revision of the Phelisterhaemorrhous species group (Coleoptera, Histeridae, Exosternini).

ABSTRACT: The Phelisterhaemorrhous species group is established here, revising the seventeen included species, four of which are described as new. This group is named for and contains the type species of Phelister, so represents a core around which a modern concept of the dumping-ground genus Phelister may be developed. The group includes several common and well-known species in the Americas, including some of the only Phelister to exhibit distinctive coloration. Several of these are typically found in cattle dung, and have likely expanded beyond their native ranges as cattle spread throughout the Americas. The group contains the following species: Phelisterhaemorrhous Marseul, 1854, Phelisteraffinis J.E. LeConte, 1859, Phelisterparallelisternus Schmidt, 1893, Phelistermobilensis Casey, 1916, Phelisterbrevistriatus Casey, 1916, Phelistersonorae sp. nov., Phelisterwarneri sp. nov., Phelisterpuncticollis Hinton, 1935, Phelistersubrotundus (Say, 1825), Phelisterrouzeti (Fairmaire, 1850), Phelisterrufinotus Marseul, 1861, Phelisterthiemei Schmidt, 1889, Phelisterparecis sp. nov., Phelisterbryanti sp. nov., Phelistervernus (Say, 1825), Phelisterchilicola Marseul, 1870, and Phelisterbruchi Bickhardt, 1920. We also designate the following new synonymies: Phelisterhaemorrhous Marseul (= Phelisterrubicundus Marseul, 1889, syn. nov.); Phelistersubrotundus (= Phelistercontractus Casey, 1916, syn nov.); Phelisterrouzeti (Fairmaire) (= Phelisterfairmairei Marseul, 1861; syn. nov., = Phelisterwickhami Casey, 1916, syn. nov.); Phelisterrufinotus Marseul, 1861 (= Epierusmarseulii Kirsch, 1873, syn. nov.); and Phelisterthiemei Schmidt, 1889 (= Phelisterstercoricola Bickhardt, 1909, syn. nov.).

Project description:The Agrilus occipitalis species-group is redefined and diagnosed. Two species from this group, Agrilus auriventris Saunders, 1873 and Agrilus occipitalis (Eschscholtz, 1822), are known as the serious pests of cultivated Citrus trees. Overall twenty-three taxa are included in the Agrilus occipitalis species-group. A complete list of references, type material, species examined and distribution is given for each taxon. The host plants, adult occurrence and altitude range is cited for most taxa. Habitus of all taxa and aedeagi of available males are pictured. Images of primary type specimens are provided. A character state matrix table for diagnostic characters is given for all taxa to facilitate their determination. The following new taxonomic and nomenclatural acts are proposed. New species:eight new species are described: Agrilus mucidus sp. n., Agrilus nebulosus sp. n., Agrilus picturatus sp. n., Agrilus pluvius sp. n., Agrilus pseudoambiguus sp. n., Agrilus tesselatus sp. n., Agrilus trepanatus sp. n. and Agrilus umrongso sp. n. Proposed synonyms: eight synonyms are proposed: celebicola Obenberger, 1924, syn. n. (synonym of occipitalis Eschscholtz, 1822); connexus Kerremans, 1900, syn. n. (synonym of occipitalis Eschscholtz, 1822); cupricauda Saunders, 1867 syn. n. (synonym of occipitalis Eschscholtz, 1822); evinadus Gory & Laporte, 1839, syn. n. (synonym of occipitalis Eschscholtz, 1822); nirius Obenberger, 1924 syn. reconfirmed (synonym of occipitalis Eschscholtz, 1822); oblatus Kerremans, 1900, syn. n. (synonym of occipitalis Eschscholtz, 1822); samoensis Blair, 1928, syn. n. (synonym of auriventris Saunders, 1873); tebinganus Obenberger, 1924, syn. n. (synonym of occipitalis Eschscholtz, 1822). New lectotype designations: six lectotypes are designated: Agrilus celebicola Obenberger, 1924; Agrilus cupricauda Saunders, 1867; Agrilus korenskyi Obenberger, 1923; Agrilus kurandae Obenberger, 1923; Agrilus nirius Obenberger, 1924; Agrilus nitidus Kerremans, 1898.

Project description: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.
