چکیده
The Neotropical genus Costitachys Erwin 1974 is revised. Newly discovered specimens of a new species of Costitachys from Ecuador provide comparative genitalic characters of males for the genus and extend its range 2900 km west of its previously known distribution into an additional center of species radiation in South America, the "North Andean Slope." A new species, Costitachys tena Erwin and Kavanaugh sp. nov. (type locality: Ecuador, Napo Province, Tena, 598 m, 0°59'S, 077°49'W) is described. One additional locality for Costitachys inusitatus Erwin is recorded from Brazil and another noted from French Guyana. A key to facilitate identification of adults of the two species is included.

The classification of the carabid subtribe Tachyina (Trechitae: Bembidiini) is reviewed in light of newly discovered diversity from Central and South America. Described herein are three new genera (Tachyxystagen. n., Stigmatachysgen. n., Nothoderisgen. n.), two new subgenera of Meotachys (Scolistichussubgen. n., Hylotachyssubgen. n.), and two new subgenera of Elaphropus (Ammotachyssubgen. n., I...
متن کاملFossil carabids from Baltic amber--III--Tarsitachys bilobus Erwin, 1971 an interesting fossil ground beetle from Baltic amber (Coleoptera: Carabidae: Trechinae): Redescription and comments on its taxonomic placement.
Tarsitachys bilobus (Coleoptera, Carabidae) is a fossil species described by Erwin from Baltic amber. Its description was based on only one known specimen, and thus, part of its anatomical structures were unknown as they were poorly preserved in the Holotype. In this paper we complete the description with a second specimen. A new placement among Tachyina and a new status for the genus are propo...
متن کاملPhylogeny of minute carabid beetles and their relatives based upon DNA sequence data (Coleoptera, Carabidae, Trechitae)
The phylogeny of ground beetles of supertribe Trechitae is inferred using DNA sequences of genes that code for 28S ribosomal RNA, 18S ribosomal RNA, and wingless. Within the outgroups, austral psydrines are inferred to be monophyletic, and separate from the three genera of true Psydrina (Psydrus, Nomius, Laccocenus); the austral psydrines are formally removed from Psydrini and are treated herei...
