The nomenclatural status of Trogoderma yunnaeunsis Zhang and Liu is clarified. T. yunnaneunsis Zhang, Liu, and Jing is found to be a junior synonym of T. yunnaeunsis. The adult is distinguished from 7 different eastern Palearctic species of Trogoderma and from the European T. versicolor (Creutzer). The mature larva of T. yunnaeunsis is described and distinguished from larvae of other Eastern Palearctic Trogoderma for which information is available.

A key to the species of adventive sap beetles of Hawaii is provided to assist in the separation of adventive species from endemics, and includes the following species: Cybocephalus nipponicus Endrödy-Younga, Conotelus mexicanus Sharp, Carpophilus (Urophorus) humeralis (F.), Carpophilus hemipterus (L.), Carpophilus (dimidiatus) dimidiatus (F.), Carpophilus (dimidiatus) freemani Dobson, Carpophilus (dimidiatus) maculatus Murray, Carpophilus (dimidiatus) mutilatus (Erichson), Carpophilus marginellus Motschulsky, Carpophilus oculatus Murray, Epuraea (Haptoncus) luteola Erichson, Epuraea (Haptoncus) munda (Sharp), Epuraea (Haptoncus) ocularis Fairmaire, Aethina (Idaethina) concolor (Macleay), Omosita discoidea (F.), Stelidota geminata (Say), Stelidota chontalensis Sharp, Phenolia (Aethinodes) attenuata (Reitter), and Phenolia (Lasiodites) limbata tibialis (Boheman). For each adventive species, general habits, island distributions within Hawaii, new collection records, and worldwide distribution are noted.

A history of taxonomic descriptions of tiger beetles (Cicindelidae) is presented from 1758, when the first species were described by Carl von Linné, to present day. The number of new species over 50 year periods shows an irregularly increasing species number that soon will exceed 2,600. Possible causes of these irregular patterns include economic and political upheavals that affected collecting and the near monopoly of descriptions by one or a few researchers during several periods. The growing influence of tiger beetles as models for patterns of use in biology, conservation, and general biodiversity are also discussed.

Illustrated descriptions of the male genitalia and notes on the spermathecae are provided for the Phanaeus vindex species group: P. vindex (Macleay), P. difformis (LeConte), and P. igneus (Macleay). These represent the first descriptions of the internal sac (aedeagus) for these species. Examination of the genital capsule (i.e., phallobase and parameres) and the sclerites within the internal sac (aedeagus) revealed only slight differences in shape and sclerotization. No differences were observed among the spermathecae of the three species.

The genus Ancistronycha Märkel is reviewed. Atalantycha, new genus, is described. Ancistronycha rufidens Marseul is transferred to Cantharomorphus Fiori as Cantharomorphus rufidens (Marseul), new combination. Ancistronycha bilineata (Say), A. dentigera (Leconte) and A. neglecta (Fall) are transferred to Atalantycha as Atalantycha bilineata (Say), new combination, Atalantycha dentigera (Leconte), new combination, and Atalantycha neglecta (Fall), new combination. Ancistronycha taygetana Pic, new synonym, is synonymized with Ancistronycha occipitalis (Rosenhauer). Keys to the species of Ancistronycha and Atalantycha are provided.

The larval stages of the Neotropical species Derallus paranensis Oliva, 1981 and Hemiosus dejeanii (Solier, 1849) are described and figured for the first time. Notes on the bionomics of these two species are included. Larvae of D. paranensis and H. dejeanii are compared to those of other Derallus Sharp and Hemiosus Sharp species. Comparative notes to differentiate larvae of two genera related to Derallus, Allocotocerus Kraatz and Regimbartia Zaitzev are provided.

The California species Eurypogon confusus Fall is redescribed and made the type of Brevipogon new genus. Generic relationships within the family are discussed, based on a cladistic analysis of all artematopodid genera, with Brachypsectra as the outgroup. Based on the cladistic analysis, the tribe Allopogonini Crowson is elevated to subfamily rank (Allopogoninae Crowson new status). A key to artematopodid genera is provided.

Two endogean carabid species of Typhlocharis in the T. gomezi species group are described, Typhlocharis passosi, new species and Typhlocharis fozcoaensis, new species. This is the first record for Portugal of species belonging to the gomezi group. We provide diagnostic characters for these species, descriptions of the new species, affinities to putative relatives and a key for the identification of the gomezi species group.

Primary types were examined for eurypine Mycteridae described by Maurice Pic. The following new synonyms are proposed [senior synonym first]: Cleodaeus rugiceps Champion 1889 = Physcius grandis Pic 1930 and Physcius crassicornis Pic 1933; Conomorphus brevicornis Champion 1889 = Conomorphus lineatus Pic 1920 and Conomorphus brevevittatus Pic 1931; Eurypus kirbyi Champion 1916 = Eurypus longipennis (Pic 1933); Eurypus rubens Kirby 1818 = Eurypus lagrioides (Pic 1920); Falsopedilus elongatus (Pic 1921) = Falsopedilus modestus Pic 1924; Microconomorphus rufipes (Pic 1907) = Microconomorphus curticollis (Pic 1907); Mimophyscius breviscutata (Fairmaire 1898) = Mimophyscius madecassus Pic 1935; Omineus Lewis 1895 = Pseudothisias Pic 1930; Phaeogala Fairmaire 1896 = Falsostictodrya Pic 1931. The following new combinations are proposed (original combinations in square brackets): Eurypus infasciata (Pic 1933) [Polypria lagrioides var. infasciata Pic]; Falsopedilus elongatus (Pic 1921) [Eurypinus elongatus Pic]; Mimophyscius breviscutata (Fairmaire 1898) [Phaeogala breviscutata Fairmaire]; Omineus bicolor (Pic 1930) [Pseudothisias bicolor Pic]; Phaeogala biimpressa (Pic 1931) [Falsostictodrya biimpressa Pic]; Trichosalpingus gracilicornis (Pic 1927) [Physcius gracil

A comparison of syntypes and a large series of specimens of Xyleborus impressus Eichhoff with specimens of X. ferrugineus (Fabricius) clearly showed the distinct validity of these two species that were previously considered synonyms. Specimens of X. impressus from 14 states in the US were examined, along with syntypes located in museums in Poland and Washington, DC. A lectotype for X. impressus is designated.

Cyclocephala magdalenae Young and Le Tirant new species is described from Huila Division, Colombia. The holotype is illustrated. Parameres of Cyclocephala magdalenae and its most similar congener Cyclocephala sexpunctata Castlenau are illustrated and a diagnosis is given to separate these two species.

Germarostes (Germarostes) carltoni, new species, keys to the subgenus Germarostes Paulian in Howden and Gill (2000). It has ten-segmented antennae, rounded anterior clypeal edge and slightly thickened outer hind tibial apices typical of the nominate subgenus but differs from all known species in the genus in being flightless and possessing very long, slender legs. This new species is described, figured and a brief discussion of its placement in the genus is given.
