AbstractThree new species of beetles in the genus Loxandrus are described: L. straneoi from the southern United States, L. icarus from the Eastern United States, and L. quinarius from central Bolivia. Loxandrus icarus, inhabitant of wet lowland habitat, is unique among eastern North American species in having reduced flight wings. The only other North American species with reduced flight wings, L. omiltemi Allen & Ball, is known from temperate cloud forest habitat in Mexico. Loxandrus quinarius…

A new Brazilian species of Loxandrus LeConte, 1852, with description of immatures and notes on natural history (Coleoptera: Carabidae: Loxandrini)

The larva differs from the known larvae of Loxandrus species mainly by being eruciform, glabrous and depigmented, its small head and legs, and the lack of stemmata and urogomphi, representing an unusual last instar type among the Carabidae.

A New Tribal Placement for Glyptolenus mirabilis (Straneo) (Coleoptera: Carabidae), comb. n., and Description of G. straneoi, sp. n. from Ecuador

Modifications to Whitehead's (1974) key are provided to permit identification of both newly recognized species of Glyptolenus.

A new species of Loxandrus LeConte (Coleoptera:Carabidae: Loxandrini) from South america

This large and robustly–built South American species is distinguished from all other loxandrines by the unequal widths of the elytral intervals, in which odd–numbered intervals are as much as twice as wide as even–numbered ones.

New Synonymies and Notes on North American Loxandrus LeConte (Coleoptera: Carabidae)

The following new synonymies within the genus Loxandrus are proposed: L. parvicollis Casey, 1918 and L. proximus Chaudoir, 1868 could not be associated with any species treated by Allen (1972) and are likely valid species.

Catalogue of Geadephaga (Coleoptera, Adephaga) of America, north of Mexico

All scientific names of Trachypachidae, Rhysodidae, and Carabidae (including cicindelines) recorded from America north of Mexico are catalogued and five new genus-group synonymies and 65 new species-groupsynonymies, one newspecies-group status, and 12 new combinations are established.

Phylogeny and classification of the genus-group taxa of Loxandrina (Coleoptera, Carabidae, Abacetini)

Bayesian and parsimony phylogenetic analyses of combined and partitioned datasets of molecular and morphological data for exemplar taxa of five outgroup and 76 ingroup abacetine carabids resulted in a monophyletic Loxandrina Erwin & Sims, 1984 that is split into Australian and American clades.



Chemical Defense in Carabids and Its Bearing on Phylogeny

The existence of chemically based defensive mechanisms in Carabidae has been known for many years, and reasonably detailed descriptions of the secretory systems and associated twin pygidial reservoirs were published at the turn of the century, although some rather wild guesses were made on the basis of odor or other uncritical data.


The compatibility of the phylogenetic species concept with various biological needs for species and its use at the exclusion of alternative species concepts are discussed.
