A new species of Urginea Steinhill. located in Andhra Pradaah and Tamilnadu (India), namely Urginea negarjunae Hemadri et Swaharl which produces the thickest scape coupled with the largest and closely arranged flowers and nonreflexed tepals among all the Indian species so far recorded under Urginea Steinhill, is described with illustrations. Chromosomal study revealed that the new taxon is not ...

A new species of brachypterous, flightless, jumping alpine Thyrocopa moth, T. kikaelekea, is described from Hawaii Island. This new species is similar to T. apatela (Walsingham), another flightless species from Maui Island. Thyrocopa kikaelekea is hypothesized not to be the sister taxon to T. apatela, instead representing an independent loss of flight.

The family Jacobsoniidae Heller () is newly recorded from China upon the discovery of Sarothriassinicus Bi & Chen, sp. n. () from Motuo, Southeast Xizang. Description and illustrations of the habitus and major diagnostic features of the new taxon are provided. A key to the species of Sarothrias and some ecological notes on the new species are presented.

Based on genetic and morphometric differences, Dietzen et al. (2003) [1] proposed to separate the Gran Canaria Robin from E. r. superbus of Tenerife as a new taxon in a nomenclaturally invalid way. Here, we provide a formal description of the new subspecies (Erithacus rubecula marionae subsp. nov.) in accordance with the rules of the International Commission of Zoological Nomenclature.

Most organisms experience competition for resources, probably most of the time. As the structure and requirements of closely related species are generally liable to be more similar than in distantly linked species, Darwin suggested that the potential for competition was greater in the former. Since that time, studies have concentrated on interactions of either conspecifics or congeneric species...

The presence of rogue taxa (rogues) in a set of trees can frequently have a negative impact on the results of a bootstrap analysis (e.g., the overall support in consensus trees). We introduce an efficient graph-based algorithm for rogue taxon identification as well as an interactive webservice implementing this algorithm. Compared with our previous method, the new algorithm is up to 4 orders of...

The family Amphipithecidae is one of the two fossil primate taxa from Asia that appear to be early members of the anthropoid clade. Ganlea megacanina, gen. et sp. nov., is a new amphipithecid from the late middle Eocene Pondaung Formation of central Myanmar. The holotype of Ganlea is distinctive in having a relatively enormous lower canine showing heavy apical wear, indicating an important func...

The concept of a "potential taxon" as a nameand literature-related data area in botanical databases is introduced. A potential taxon is a name with taxon circumscription information attached to it by means of one or more literature references. As a compromise solution between linking information in database systems entirely to specimen data or only to accepted names, using potential taxa can ef...
