Mathis, Wayne N. Studies of Ephydrinae (Diptera: Ephydridae), I I I : Revisions of Some Neotropical Genera and Species. Smithsonian Contributions to Zoology, number 303, 50 pages, 77 figures, 1980.—The systematics phylogeny, classification, and natural history of four genera, three subgenera, and one species of a fourth subgenus of Neotropical Scatellini are revised. Other taxa of Scatellini no...

All of the known species of the Chinese endemic subgenus Pterostichus (Circinatus) are revised, keyed, and illustrated. Eleven new species and one new subspecies are described: Pterostichus adelphus sp. n. (Sichuan: Meigu, N28.66°, E103.06°); Pterostichus ailaoicus sp. n. (Yunnan: Xinping, N23.94°, E101.50°); Pterostichus camelus sp. n. (Sichuan: Mianning, N28.97°, E102.16°); Pterostichus dimor...

Crematogaster ants are diverse, widespread and abundant in tropical, subtropical and warm-temperate climates throughout the world. The species diversity of this genus has been notoriously difficult to manage based upon morphology alone, and former attempts have generated a vaguely defined subgeneric system. I propose an improvement of the previous subgeneric classification and recognize two sub...

Systematic investigations and phylogenetic analyses have indicated that Astelia, as currently circumscribed, is paraphyletic, with Collospermum nested within it. Further, AsteliasubgenusAstelia is polyphyletic, and Astelia subgenera Asteliopsis and Tricella are paraphyletic, as currently circumscribed. Revision of the subgeneric classification of Astelia is warranted to ensure classification ac...

Linaria Mill. (Plantaginaceae) with about 160 spp. is the largest genus of the tribe Antirrhineae. We conducted phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer region (ITS) and chloroplast DNA (rpl32-trnL) sequence data to test the monophyly of currently recognized sections in Linaria. For this purpose 86 species representing seven sections of Linaria and one species ...

BACKGROUND AND AIMS Anthurium is an important horticultural crop from the family Araceae, order Alismatales, a lineage considered to have diverged from other monocots prior to the cereals. Genome size and its distribution in Anthurium were investigated to gain a basic understanding of genome organization in this large genus and to forge a firm foundation for advancement of molecular approaches ...

Scutellaria with about 360 species is one of the largest genera of Lamiaceae. The Iranian highlands accommodate about 40 Scutellaria spp., and is considered as one of the main centers of diversity of the genus. Here, we present a phylogenetic study for 44 species of Scutellaria especially from Iranian highlands, representing major subgeneric taxa, based on nuclear rib...
