dc.description.abstract"In the present report, the third in a series on Bledius, the annularis and emarginatus groups are discussed and a new species is described in the aequatorialis group. A key to the species, descriptions, diagnoses, illustrations, and distributional and habitat data for each species are presented. Bledius habrus, melanocolus, aurantius, jucundus, naius, nardus, omega, venus, viriosus, wudus, and zophus are newly described. Thirteen nominal species are recognized as synonyms. Bledius albidipennis Bernhauer and ornatus LeConte are new junior synonyms of albonotatus Mäklin; apicalis Fall is a new junior synonym of diagonalis LeConte; adjustus Casey and transitus Fall are new junior synonyms of gentilis Casey; kincaidi Hatch is a new junior synonym of parvicollis Casey; rusticus Fall is a new junior synonym of bicolor Casey; luteipennis LeConte, medialis Fall, oregonensis Hatch, and pleuralis LeConte are new junior synonyms of suturalis LeConte; and borealis Blatchley and bowronensis Hatch are new junior synonyms of turgidus Casey. The species in the United States included in the emarginatus group are cognatus LeConte, emarginatus (Say), and wudus Herman. They are found in the eastern and southeastern United States. The species are similar and not easily distinguished. Bledius albonotatus Mäklin, aurantius Herman, bicolor Casey, cedarensis Hatch, confusus LeConte, diagonalis LeConte, gentilis Casey, gracilis Casey, habrus Herman, jucundus Herman, laticollis LeConte, melanocolus Herman, monticola Casey, naius Herman, nardus Herman, newelli Hatch, omega Herman, parvicollis Casey, persimilis Fall, phytosinus LeConte, ruficornis LeConte, suturalis LeConte, tarandus Herman, tau LeConte, turgidus Casey, venus Herman, villosus Casey, viriosus Herman and zophus Herman are species from the United States and Canada included in the annularis group and which I can identify. Also included in the annularis group are nine species listed together in what I call the annularis complex: annularis LeConte, breretoni Hatch, honestus Casey, languidus Casey, mysticus Fall, nebulosus Casey, sinuatus LeConte, stabilis Casey, and washingtonensis Hatch. After years of study and collecting I have been unable to resolve the species of this complex which is widespread in Canada and the northern United States. I was unable to resolve three other species: fasciatus (Say), longipennis Mäklin, and verticalis Notman; the types of each have been lost but I discuss each of them. The annularis group species are widespread in the United States and Canada and most are found in shaded soil near fresh water. Only two, albonotatus and newelli, are associated with coastal, saline habitats. Several species, notably ruficornis, tarandus, and turgidus, have transcontinental distributions, and one, albonotatus, is found along the coast from western Alaska to Baja California. The addition of a new species, susae, to the aequatorialis group brings that group up to four. However, susae is the only one of the group known only from the United States which is found only on the mainland. It is also the sole species of Bledius in which the females have a pronotal horn; although pronotal horns are known in a number of New and Old World species, heretofore no females have been reported with such a modification. Since publication of Parts I and II of this monograph, I have examined over 6000 more specimens of 41 previously revised species. In Appendix II all the new records are included; for many species extensions of their previously known range are recorded. Lectotypes are designated for the species of Bledius described by LeConte, Casey, and Fall. For Part III, 28,408 specimens were examined"--P. 4.en_US
