A New Species

Water striders (pond skaters) occur worldwide and are conspicuous in most aquatic environments, but the taxonomy of many groups remains unresolved. Here we revise the South American species of the Palaeo- and Neotropically distributed Cylindrostethus Mayr, 1865, a genus characterised by its long, cylindrical body and fast jumping-gliding locomotion. Using a cladistic analysis of morphological characters, we confirm the subdivision of Neotropical Cylindrostethus into two major groups. Nine species of Cylindrostethus are recognised from South America, one of which was recently discovered in Amazonian Brazil and Peru: C. bassleri Drake, 1952; C. bilobatus Kuitert, 1942; C. drakei, sp. nov.; C. hungerfordi Drake & Harris, 1934; C. linearis (Erichson, 1848); C. meloi Floriano & Cavichioli, 2013; C. palmaris Drake & Harris, 1934; C. podargus Drake, 1958; C. regulus (White, 1879). Two species are placed in synonymy: (C. podargus = C. stygius Drake, 1961, syn. nov.); (C. linearis = C. erythropus (Herrich-Schäffer, 1850), syn. nov.). A key to the nine species is provided, along with detailed descriptions and illustrations.

Young Sporophytes

The South American species of Desmarestia are revised using morphological features of field sporophytes and reproductive and ontogenetic characters obtained from laboratory culture of gametophytes and young sporophytes. Ten entities including a new species are recognized: D. chordalis, D. confervoides comb.nov., D. distans, D. firma, D. gayana, D. ligulata, D. muelleri sp.nov., D. patagonica, D. peruviana, and D. tropica. Although the taxa were distinguished in part using features of the life history in culture, most field thalli can be identified using morphological characters. A key to the South American species of Desmarestia is provided. Key words: culture study, Desmarestia, Desmarestia confervoides comb.nov., Desmarestia muelleri sp.nov., Phaeophyceae, South America, taxonomy.

The Creation

AbstractIn this study Parorphula is re-described based on characters from the external morphology and genitalia. This genus comprised two species: P. pallidinota and P. latipennis, that were described based mostly on characters from external morphology. The morphological analysis conducted in this study plus the support of results from a cladistic analysis showed that external morphological characters justify the creation of a new genus for P. latipennis. Therefore, the genus Neorphula is proposed and the new combination is established.

A New Species

A new species of the diverse augochlorine bee genus Chlerogella Michener (Halictinae: Augochlorini) is described and figured from southwestern Colombia.  Chlerogella anchicaya Engel, Gonzalez, & Hinojosa-Díaz, new species, is similar to C. agaylei Engel and C. materdonnae Engel, both occurring on the eastern slopes of the Andes in Ecuador.  There are also some similarities with C. eumorpha Engel from the western Andean foothills in northern Ecuador, but differences in rostral length and male terminalia can distinguish these species.  Revised couplets are provided to the South American species of Chlerogella to permit identification of the new species.

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.

In the present work based on material from several areas in Brazil, the species of Americabaetis represented in the country are revised. A new species, A. mecistognathus, sp. nov., is described based on nymphs from Santa Catarina, the male adult of A. labiosus Lugo-Ortiz & McCafferty is described, a key to the nymphs of the South American species is provided, whereas comments regarding the taxonomy and habitat distribution of the Brazilian species are presented.

A New Species

A new species of Chysis sect. Chysis is described from the Central-West region of Brazil. It is similar to C. aurea and C. bruennowiana, the other two South American species of the genus, but differs in the pale pink perianth with magenta stripes or dots on the labellum and on the abaxial surface of the column, and by a labellum that is wider than long with the mid-lobe not surpassing the length of the lateral lobes. The species, which confirms the presence of the genus in the Brazilian plateau, had been previously misidentified as C. laevis. Photographs, an illustration, and a key to the South American species are provided.

We report here for the first time horsehair worms (Nematomorpha) from Hong Kong (China). Most specimens belong to the genus Chordodes, and can be assigned to C. bipilus, C. caledoniensis and to C. cf. moutoni. Two specimens have a cuticular pattern resembling the South American species C. peraccae or C. bouvieri, but for Southeast Asia this pattern is new. These two specimens are reported here as Chordodes sp. Additionally, Gordionus chinensis was found. One new species, Acutogordius koljai, is described from Malaysia. It has a characteristically-structured region posterior to the postcloacal crescent which sets it apart from previously described species in this genus.
