Dryocalamus subannulatus is reported for the first time from Myanmar. A single individual was found on the Thayawthadangyi Island Group in the Myeik Archipelago, Tanintharyi Region. Morphological features and a maximum likelihood analysis of the 16S mitochondrial gene confirm its identity. This specimen represents the first record of D. subannulatus north of the Isthmus of Kra.

We here transfer an euptychiine taxon hitherto placed in the polyphyletic genus Magneuptychia Forster, 1964, to Caeruleuptychia Forster, 1964. Caeruleuptychia francisca (Butler, 1870), n. comb. is reclassified based on a morphology-based maximum likelihood analysis, which is consistent with ongoing analyses of molecular data. Two putative synapomorphic characters are identified for the “Caeruleuptychia umbrosa clade”, one of which appears to be an unusual characteristic of euptychiine butterflies and is tested by optimizing onto the maximum likelihood tree. We also discuss the systematic placement of three additional enigmatic Caeruleuptychia species. A lectotype is designated for Euptychia francisca, and the genitalia of this species are illustrated here for the first time.

The new delphacid genus Akemetopon gen. n. (Delphacinae: Delphacini) is described and illustrated with 3 new species from Arizona and Mexico: Akemetopon inornatum sp. n., A. politum sp. n., and A. ainigma sp. n. A key to species is provided. The barcoding portion of the mitochondrial gene Cytochrome Oxidase I (COI) was sequenced for A. politum sp. n. A maximum likelihood analysis places this genus in the basal Delphacini.

ABSTRACT Statistical techniques are presented for the analysis of geographic variation in allelic frequencies. Likelihood ratio test criteria are derived from a multinominal sampling distribution, and are used to answer three questions. (1) Are there geographic differences in allelic frequencies? (2) Are population differences in allelic frequencies associated with environmental differences? (3) Is there any residual "lack of fit" variation among populations, after accounting for that variation associated with environmental differences? The two- and three-allele cases are explicitly treated, and the extension to more alleles is indicated.

Postweaning liveweight gain records of 1610 young bulls obtained both in feedlot and under pasture were used to estimate (co)variance components using a multivariate restricted maximum likelihood analysis. The pedigree file included 3477 animals. Heritability estimates for liveweights and gain in both environments correspond to most previously reported estimates. The genetic correlation of gain between the 2 environments was -0·12, suggesting a large genotype testing environment interaction and re-ranking of animal breeding values across environments. Results of this analysis suggest the need for environment-specific breeding values for postweaning gain.
