Three new species of Cloeodes are described from Argentina (C. barituensis, C. espinillo and C. opacus), based on nymphs and from adults for the first two species. Two species, C. stelzneri and C. nocturnus, are proposed as nomen dubia. The only other species from Argentina, C. penai, is revised. The validity of the monotypic genus Bernerius is analyzed. A cladistic analysis including five species of the genus Cloeodes and Bernerius is presented and the synonymy of the latter is confirmed. A key for South American species of Cloeodes is presented.

Six new species of Paracloeodes are described: four from Brazil (P. assu, P. atroari, P. peri and P. waimiri), one from Argentina (P. yuto) and one from Bolivia (P. pacawara), based on nymphs. Three other species from South America: P. binodulus, P. eurybranchus and P. ibicui are revised. A cladistic analysis including most of the South American species of Paracloeodes and the monotypic genus Iguaira is presented. A key for all South American species is included.

Three New Species

The South American species of Pseudocanthon Bates, 1887 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini) are reviewed. In this work, 10 valid species and two subspecies are recognized for the genus. Among these species, five are recorded in South America, including three new species: P. perplexus (LeConte, 1847), P. xanthurus (Blanchard, 1847), P. vazdemelloi new species, P. pantanensis new species, and P. chaquensis new species. A lectotype is designated for P. xanthurus (Blanchard, 1847). In this revision, each species is analyzed as follows: a detailed literature review, an identification key for the South American species, a diagnosis, descriptions, illustrations of key morphological characters, list of examined material, and geographic distribution.

Three New Species

The South American species of the genera Askola and Hagenulopsis are revised. Three new species of Askola from Brazil are described based on male imagos. Askola emmerichi sp. nov. and A. paprockii sp. nov. present spotted wings, but differ in general coloration and details of genitalia; Askola cipoensis sp. nov. is easily distinguished because the male eyes being widely separated on meson of head. Three new species of Hagenulopsis are also described: H. lipeo (from Argentina and Bolivia) and H. zunigae (from Colombia), both described from imagos and nymphs, can be recognized by details of coloration and male genitalia. H. esmeralda sp. nov. from Ecuador, described from imagos, shows a distinct male genitalia and translucent male abdomen. A key to species for the the male and female imagos of Askola and Hagenulopsis species is provided.

First Time

The genus Cloeodes is poorly reported for Uruguay, until now only C. aymara was described from this region. Here we describe three new species of Cloeodes from this country: C. dialutoi, C. guenoa and C. vaimaca, all of them based on nymphs. The species C. opacus is reported for the first time in Uruguay. A discussion of each taxon is included as well as drawings of the new species. A revised and updated key for male imagos and nymphs of South American species of Cloeodes is presented.

Three new species of Senecio (Compositae: Senecioneae) from Central Peru are described and illustrated. Morphological characters are used in order to distinguish them from the closest species. Senecio crassiandinus Montesinos & Pino has succulent leaves with cuticle composed of translucid white glands, bright yellow disc florets with blotches of pale reddish-brown in the corolla throat and linear-oblong achenes covered with trichomes, which distinguish it from the other South American species of the genus. Senecio inghamii Montesinos has oblanceolate-ovate to rhombic-quadrate leaves, short-sized, with serrate-quadrate dentation, upper surface lustrous and glossy, lower surface densely covered with whitish lanuginose pubescence, capitules bear trilobulated ray florets, achenes copiously covered by fimbriate hairs which differentiates it from its closest relative, S. pensilis Greenm. Senecio roseoandinus Montesinos & R. Zárate is a unique pubescent species characterized for being a perennial rhizomatous herb, with lanuginose and arachnoid trichomes, leaves elliptic-lanceolate, thick, densely arachnoid to glabrous (lustrous, glossy, dark green), margin entire to crenate, synflorescence in racemes, capitules discoid, corolla pale yellow but turning fuchsia-pink at maturity, achenes oblong, striate, and glabrous. All three new species are distributed in the Alto Marañon river mountain slopes, at altitudes ranging from 2000 up to 4200 m a.s.l. The species are, so far, only known from their type localities in the Huánuco region.

New Synonymy

Based on specimens recently collected from Brazil, two new species of Ulmeritoides, as well as the nymph and female imago of the atypical U. flavopedes are described. A new synonymy is proposed, U. flavopedes (=U. oepa). In order to re-evaluate the relationships of the species of the Ulmeritus-Ulmeritoides group based on these new evidences, a cladistic analysis is carried out. The monophyly of Ulmeritus and Ulmeritoides is reconfirmed, and a clear differentiation between the Central and South American species of Ulmeritoides emerges from the analysis.

On comparing the figures it will be observed that all the specific characters of Tetrophthalmus titan (A in all figures) closely resemble those of T. subtitan (B in all figures), and that these two species constitute one group; also that the specific characters of T. africanus (C in all figures) closely resemble those of T. australis (D in all figures), and that these species belong to another group, which must also include T. chilensis.Judged by their parasites, the Ethiopian pelican, Neopelecanus rufescens, is more closely allied to both the Australian pelican, Catoptropelecanus conspicilatus, and the South American species, Pelecanus thagus, than it is to either Pelecanus onocrotalus or Metapelecanus roseus, both of which also occur in the Ethiopian region. Moreover, if the parasites throw any light on the phylogeny of their hosts, thagus cannot remain in the genus Pelecanus along with onocrotalus if the genera Neopelecanus, Metapelecanus and Catoptropelecanus are to remain valid.
