Two New Species

In this paper we re-evaluate Cyanallagma Kennedy 1920, which currently includes 15 species, and we address another five species that share diagnostic characters with some of them but are currently placed within Leptagrion Selys 1876, Mesamphiagrion Kennedy 1920, and Telagrion Selys 1876. A new genus, Oreiallagma, is described to include five species originally placed in Acanthagrion Selys 1876, Cyanallagma, and Telagrion. These species are O. thelkterion (De Marmels 1997) (type species), O. acutum (Ris 1918), O. oreas (Ris 1918), O. prothoracicum (Kimmins 1945), and O. quadricolor (Ris 1918). The last stadium larva of O. quadricolor is described. The remaining species currently includedin Cyanallagma are allocated to two separate genera: Cyanallagma sensu stricto and Mesamphiagrion. Cyanallagma sensu stricto comprises southern South American species including the type species, Cyanallagma interruptum (Selys 1876). Mesamphiagrion Kennedy 1920 includes a cluster of species from northwestern South America that are considered congeneric with the type species Mesamphiagrion occultum (Ris 1918). Two new species from Ecuador, M. dunklei and M. ecuatoriale, are described and Argia hebdomatica Navás 1934 is found to be a junior synonym of M. ovigerum (Calvert 1909). Synonymic lists, diagnoses, illustrations, keys, and distribution maps for the three genera are provided.

Urticating Hairs

A new genus Ami Pérez-Miles is proposed for six new species: A. caxiuana Pérez-Miles, Miglio & Bonaldo, from Caxiuanã National Forest, Pará, Brasil, the type species; A. yupanquii Pérez-Miles, Gabriel & Gallon, from the area of Puyo, Equador; A. bladesi Pérez-Miles, Gabriel & Gallon, from Isla Colón, Panamá; A. pijaos Jimenez & Bertani, from Ibagué, Tolima, Colombia; A. amazonica Jimenez & Bertani, from Leticia, Amazonas, Colombia; and A. weinmanni PérezMiles, from La Azulita, Apure, Venezuela. Avicularia obscura (Ausserer 1875) is transferred to Ami and re-diagnosed. Diagnostic characters of Ami are the modification of Type I urticating hairs, with unusually longer area b, and one or two subconical processes on retrolateral face of male palpal tibiae. Females of Ami differ further from those of other theraphosid genera by their highly characteristic spermathecae: paired ventral receptacles attached to an almost discrete, semicircular, sclerotized back-plate.

Species Study

The bee fly genus Hemipenthes Loew in the New World reflects a heterogeneous assemblage of species. Study of species attributed to Painter & Painter’s 1962 Villa “celer” group (the species were later transferred to Hemipenthes) from the southern United States, and Central and South America shows a suite of characters that separate it from Hemipenthes s. str. and it is here described as the new genus Ins Evenhuis, n. gen. with its type species Anthrax ignea Macquart. Eight described species are here transferred to Ins: Ins celeris (Wiedemann, 1828), n. comb., Ins constituta (Walker, 1852), n. comb.; Ins curta (Loew, 1869), n. comb., Ins ignea (Macquart, 1846), n. comb.; Ins leucocephala (Wulp, 1886), n. comb., Ins martinorum (Painter, 1962), n. comb., Ins minas (Macquart, 1848), n. comb., and Ins pleuralis (Williston, 1901), n. comb. Two new species, Ins pectorcolumbo Evenhuis, n. sp. from El Salvador and Ins zanouts Evenhuis, n. sp. from Panama and Costa Rica are described and illustrated. The holotype of Anthrax divisa Walker, 1852, has been examined and found to be conspecific with Ins minas (Macquart, 1848), n. syn., and Anthrax galathea Osten Sacken, 1886 is found to be synonymous with Ins constituta (Walker, 1852), n. syn. Two other South American species currently in Hemipenthes, H. melaleuca (Wiedemann), and H. ruficollis (Bigot) are here transferred to Chrysanthrax, n. combs. A key to species in the genus is given.

World Distribution

The araneid genus Larinia Simon currently includes 56 species, eleven of them with New World distribution (World Spider Catalog, 2016). North American species of the genus were revised first time by Levi (1975) and South American species by Harrod et al. (1991). According to these authors there are four species known from subtropical South America (Larinia bivittata Keyserling 1885; L. montecarlo (Levi, 1988); L. t-notata (Tullgren, 1905); L. tucuman Harrod, Levi & Leibensperger, 1991) and also four species known from tropical South America (L. ambo Harrod, Levi & Leibensperger, 1991; L. directa (Hentz, 1847); L. lampa Harrod, Levi & Leibensperger, 1991; L. neblina Harrod, Levi & Leibensperger, 1991). According to Buckup et al. (2010) a total of 209 species of Araneidae are recorded for state of Rio Grande do Sul, including the three species L. bivittata, L. montecarlo and L. t-notata.

A New Species

A new genus, Drepanoneura (type species Drepanoneura loutoni sp. nov.), is described to include Epipleoneura letitia Donnelly, Protoneura peruviensis Fraser, and six new congeneric species from South America: D. donnellyi, D. flinti, D. janirae, D. loutoni, D. muzoni, and D. tennesseni. Drepanoneura is similar to Epipleoneura and Epipotoneura in venational characters, but differs from them in morphology of male cercus, genital ligula, female pronotum, and epiproct. A new species of Epipleoneura from Venezuela, E. demarmelsi, and a new species of Epipotoneura from Brazil, E. machadoi, are described, and diagnostic illustrations for the poorly known Epipotoneura nehalennia Williamson are also presented. A generic characterization, diagnoses, and keys for species of Drepanoneura are provided, as well as diagnostic illustrations and distribution maps for all involved species.

Two new species of Juncus from South America are described, illustrated, and a key is provided to separate the two species from related South American species in Juncus sect. Ozophyllum. Juncus andinus is similar to J. ecuadoriensis from Venezuela, Colombia, and Ecuador, but is different in having smaller seeds and conspicuous cataphylls; it is distributed in the Andes from southern Ecuador to southern Peru. Juncus austrobrasiliensis, from Brazil, resembles J. micranthus but differs in having smaller, castaneous flower-heads and capsules with beaks that clearly protrude from the flower; it is distributed in southern Brazil from São Paulo to Santa Catarina.

New Distribution

Nine species of the genus Dasymutilla Ashmead have been recorded from South America. One additional species, D. campogrande Manley & Pitts was erroneously recorded from Mexico but is from Brazil, and another species, D. colorado Cambra, Williams & Quintero was recently discovered in Colombia. Four of these nine Dasymutilla belong to a new genus, Quwitilla Williams, Bartholomay & Cambra, gen. nov., which includes: Q. peruviana (Suárez), comb. nov. (and its newly recognized female D. homochroma Suárez, syn. nov.; Q. bellatrix (Manley & Pitts), comb. nov. (based on female only); and Q. blattoserica (Kohl) comb. nov. (type species, already known from both sexes). Two others are actually synonyms of previously recognized Traumatomutilla André species: Dasymutilla brazilia Manley & Pitts, syn. nov. is a junior synonym of T. oculifera (Smith), and D. campogrande, syn. nov. is a junior synonym of T. inermis (Klug). One species is transferred out of Dasymutilla: Xystromutilla aequatorialis (André), comb. nov. Finally, updates and comments are provided on the distribution of D. araneoides (Smith), D. colorado, D. paradoxa (Gerstaecker), and D. pulchra (Smith), the only four South American species remaining in the genus Dasymutilla.
