Partial sequences (681 bp) of the mitochondrial gene, cytochrome c oxidase subunit II (COII), were used to assess the genetic diversity among populations of the Oriental butterfly, Kallima inachus (Doyére 1840) (Lepidoptera: Nymphalidae: Kallimini), distributed through the southeastern Asian tropical and subtropical areas. Two haplotypes from Tibet and the Hainan Island are deeply divergent from each other, as well as from all other haplotypes (5.43%–7.05%, uncorrected), implying cryptic species might exist in the present morphological species K. inachus. Haplotypic divergences within the range north from Guangxi and within southern Yunnan are quite shallow. Phylogenetic analysis show the population in southern Yunnan should be an evolutionary significant entity distinct from the inland China populations, while those in the Sichuan Basin, southeast mainland China and the Taiwan Island are not genetically subdivided, suggesting the status of subspecies K. i. formosana Fruhstörfer, 1912 should be reconsidered. The rapid uplift of the Qinghai-Tibet Plateau as well as dramatic climatic changes from the late Pliocene in the region could have served as main driving forces of the allopatric divergences within K. inachus, as well as among probable cryptic sibling species.

A one year study of abundance and flight periods of adult Copaxa lavendera (Westwood), 1853, collected with Malaise trap and black light, from Sierra de Las Navajas, a small mountain chain subsidiary to the Sierra Madre Oriental, in Hidalgo state, Mexico, is presented. Activity of the species was during rain season (March through August), with peaks of abundance in June and August. From published records, as well as specimens in the National Insect Collection of the Instituto de Biología, Universidad Nacional Autónoma de México, a general description of the species distribution in Mexico is presented. New records are presented for the states of Estado de México, Hidalgo, Michoacán, Puebla, Querétaro, and Tamaulipas.

Se presenta un estudio anual de la abundancia y períodos de vuelo de adultos de Copaxa lavendera (Westwood), 1853, recolectados con trampa Malaise y luz negra en la Sierra de las Navajas, una pequeña cadena subsidiaria de la Sierra Madre Oriental, en el estado de Hidalgo, México. La actividad de la especie fue durante la estación lluviosa (marzo a agosto), con picos de abundancia en junio y agosto. A partir de registros publicados, así como de ejemplares en la Colección Nacional de Insectos del Instituto de Biología, Universidad Nacional Autónoma de México, se presenta una descripción general de la distribución de la especie en México. Se presentan nuevos registros para el Estado de México, Hidalgo, Michoacán, Puebla, Querétaro y Tamaulipas.

We report new records for eight aquatic insect taxa in Alaska, each representing a North American range extension. The new records, collected primarily from non-wadeable streams and lentic habitats, consist of four mayflies (Ametropus neavei McDunnough 1928, Caenis amica Hagen 1861, C. youngi Roemhild 1984, and Labiobaetis dardanus McDunnough 1923), three caddisflies (Philarctus bergrothi McLachlan 1880, Sphagnophylax sp. and Triaenodes injustus Hagen 1861), and one stonefly (Malenka sp. Ricker 1952). Our surveys throughout Alaska suggest that the distribution and diversity of aquatic insects in non-wadeable streams and lentic habitats is poorly documented compared to that in wadeable streams. Samples from 85 lakes, ponds, and non-wadeable streams produced seven of the new records while samples from 450 wadeable streams produced only one (i.e., Malenka sp.). Further, our sampling shows that two of the taxa, C. youngi and L. dardanus, are common and abundant within their respective habitats throughout the geographic extent of our sampling.

A new species of Novantinoe Santos-Silva & Hovore 2007 is described from Panama. Modified key couplets including the new species are included.

We report Prolixocupes lobiceps (LeConte) from Baja California, México. This is the first record of the family Cupedidae and the suborder Archostemata from México, as well as Middle America. Two recent specimens collected at El Berrendo represent the most southern distribution for the species. A review of museum collections yielded four additional northern Baja California records based on a total of 10 specimens. The known distribution of the species for the United States (California and Arizona) is illustrated.

Reportamos a Prolixocupes lobiceps (LeConte) para Baja California, México. Este es el primer registro de la familia Cupedidae y del suborden Archostemata para México, así como para Centroamérica. Dos especímenes recientes recolectados en El Berrendo representan la distribución más sureña de la especie. Una revisión de colecciones de museo proporcionó cuatro registros adicionales del norte de Baja California con un total de 10 especímenes. Se ilustra la distribución conocida de la especie en los Estados Unidos (California y Arizona).
