Taxonomy of the Neotropical Genus Americabaetis,New Status (Insecta: Ephemeroptera: Baetidae)

Americabaetis (Insecta: Ephemeroptera: Baetidae), previously considered synonymous with Acerpenna, is reinstated and given generic rank. The genus differs from Acerpenna in lacking hindwings, gills on abdominal segment 1, and a conical process between the male genital forceps, and in possessing apically rounded gills on abdominal segment 7. The genus has a general Neotropical distribution with a northern limit in east-central Mexico. Five new species of Americabaetis are described from South America: A. alphus, new species, from Argentina, Bolivia, Brazil, Chile, and Paraguay; A. labiosus, new species, from Brazil, Paraguay, and Uruguay; A. longetron, new species, from Brazil, Paraguay, and Uruguay; A. maxifolium, new species, from Paraguay; and A. titthion, new species, from Brazil. Americabaetis boriquensis, new combination; A. intermedius, new combination; A. naranjoi, new combination; A. pleturus, new combination; and A. robacki, new combination, are reviewed.

A new species of Agrostis (Gramineae) in the A. alpina complex

A new species of Agrostis L. (A. barceloi ) is described from the northern mountains of Mallorca (Balearic Islands). The new taxon belongs to sect. Agtush and is mainly related to A. alpina Scop. and A. schleicheri Jord. & Verl. on morphological grounds. However, A. barceloi differs from A. alpina by its narrowly-lanceolate inflorescence, with panicle branches erect during and after anthesis, non-scabrid leaves, and by smaller lemmas and others. The new species is distinguished from A. schleicheri by the smaller spikelets, lemma, palea, and anthers. In addition, A. barceloi is tetraploid (2n = 28), and differs cytologically from the diploid A. alpina (2n= 14) and the hexaploid A. schleicheri (2n = 56).

The first phylogenetic analysis of Lamprosomatinae based on adult morphological caharacters is conducted. Comparisons are made among lamprosomatine tribes and genera. A key to tribes is provided.

Taxonomy and phylogeny of a new Central American beetle genus: Catrachia (Coleoptera: Scarabaeidae)

A new genus and two species of Melolonthinae from Honduras and Nicaragua are described. A phylogenetic analysis, carried out using morphological characters, suggests that Catrachia is a strongly supported monophyletic group. Catrachia is therefore established as a new genus, constituted by two new species, Catrachia mariana and Catrachia nica.     

A new species of Arenaria subgenus Odontostemma from Tibet, with a review of the status of the genus Gooringia (Caryophyllaceae)

A specimen collected in southern Tibet in 1928, hitherto identified only as "Arenanu sp.", is found to represent a new species of the subgenus Odontostemma . The new species resembles A. littledalei , the species that forms the basis of the monotypic genus Gooringia , characterized by a dwarf habit, a tetramerous perianth and only two or three stamens. Several other species of Arenaria subgenus Odontostemma resemble A. littledalei in habit and one ( A. saginoides ) is tetramerous, but hitherto none has been found with its extremely reduced androecium. The new species has an identical androecium to A. littledalei and its discovery leaves no doubt that Gooringia should not be recognized taxonomically at any rank. The new species is described as A. pharensis McNcill & Majumdar and a table compares its diagnostic features with those of A. littledalei and five other dwarf Arenaria species of sibgrnus Odontostemma from the mountains of Sikkim, Tibet, Yunnan and Tsinghai.
