The biodiversity of northern South American and Central American Liogenys Guérin-Méneville, 1831 (Coleoptera: Scarabaeidae: Melolonthinae: Diplotaxini) is reviewed. Four new species are described: L. clipeosetosa Cherman, new species; L. genieri Smith & Cherman, new species; L. granadina Cherman, new species; and L. schneiderae Cherman, new species. The male of L. quadridens (Fabricius, 1798) and the female of L. quadridentata Blanchard, 1851 are described for the first time. Liogenys gebieni Moser, 1921 is a new junior subjective synonym of L. macropelma Bates, 1887. The northernmost record of Liogenys is emended to Trinidad and Tobago for L. granadina Cherman, new species and L. schneiderae new species. Diplotaxis puberea cuprascens (Bates, 1887) new combination, Diplotaxis puberea puberea (Bates, 1887) new combination, and Diplotaxis pubisternis (Bates, 1887) new combination are all transferred from Liogenys to Diplotaxis Kirby, 1837. Lectotypes are designated for Liogenys gebieni Moser, 1921; Melolontha quadridens Fabricius, 1798; and Liogenys quadridentatus Blanchard, 1851. An identification key to northern South American Liogenys is presented.

A New Species

The genus Megarthrus Curtis 1829 with about 139 species described around the world, is the largest of the subfamily Proteininae (Coleoptera: Staphylinidae) (Cuccodoro 2011). Megarthrus is distributed worldwide (Cuccodoro 1999) but it is apparently more diverse in the Holartic region (Navarrete-Heredia et al. 2002). However, the South American fauna is underestimated because many of the collected specimens are not yet described (Cuccodoro 2011). Newton et al. (2005) cited the genus as probable in Colombia because some species are known from Central America and northern South America, but until now, no species has been published from Colombia. Therefore, M. andinus sp. nov. represents the first record of the genus and subfamily for this country.

A New Species

Obtusitermes Snyder is a genus endemic to the Neotropics, restricted to northern South America and southern Central America. Obtusitermes panamae Snyder was described from Quipo, Panama. Herein, we describe Obtusitermes formosulus, n. sp., from Venezuela and Trinidad and Tobago, based on the dimorphic soldier and polymorphic worker. These descriptions provide strong evidence that Parvitermes bacchanalis Mathews should not be included in Obtusitermes.

Morphological And Molecular Data

The skink genus Marisora ranges from Mexico to northern South America and occurs on some islands in the Caribbean Sea. We conducted a revision of the genus Marisora from Mexico and Central America, using new morphological and molecular data, and find support for the five previously described species (Marisora alliacea, M.aurulae, M. brachypoda, M. magnacornae, and M. roatanae) and describe four new species: Marisora lineola sp. nov., M. aquilonaria sp. nov., M. syntoma sp. nov., and M. urtica sp. nov. We show that two species previously known only from Central American islands, M. magnacornae and M. roatanae, also occur on the adjacent mainland and that two species recently placed in Alinea belong to this evolutionary clade: Marisora berengerae n. comb. and Marisora pergravis n. comb. Together with M. falconensis and M. unimarginata, these 13 species of Marisora arose mostly in the Pliocene and are largely allopatric but are sympatric and nearly sympatric at several locations in Central America where they maintain their morphological and genetic distinctiveness.

The Epicauta vittata group are commonly known as striped blister beetles and was defined by previous authors to include 32 species, 18 from North America, Central America and northern South America, and 14 from southern South America. In the present revision we revised 22 species from South America, excluding the following southern South American species: E. borgmeieri Denier, 1935; E. floydwerneri Martínez, 1955; E. franciscana Denier, 1935; E. fulginosa (Oliver, 1795); E. purpureiceps (Berg, 1889); E. rutilifrons Borchmann, 1930; and E. zebra (Dohrn, 1876) because they do not have the diagnostic characters of the group. The species of the E. vittata group from southern South America are: E. bosqi Denier, 1935; E. clericalis (Berg, 1881); E. grammica (Fischer, 1827); E. leopardina (Haag-Rutemberg, 1880); E. luteolineata Pic, 1933; E. missionum (Berg, 1881); E. monachica (Berg, 1883); E. rutilifrons Borchmann, 1930; plus two more species E. excavata (Klug, 1825); and E. semivittata (Fairmaire, 1875) until now not included in other groups. We provide a complete diagnosis of the E. vittata group from southern South America, redescribing and illustrating all included species. Detailed descriptions and illustrations of female and male genitalia are presented for the first time for these species. Finally, we provide an identification key for the ten species presently included in the E. vittata group, and update the geographic distribution of each species.

Citharexylum L. belongs to the recently circumscribed tribe Citharexyleae of the Verbenaceae, along with Rehdera Moldenke. It comprises around 50 to 60 species of trees and shrubs growing in the Neotropics. A complete taxonomic revision of Citharexylum in South America is here provided for the first time. Thirty taxa are present in South America, 27 of these are endemic, and three of them also grow in Central America. Detailed morphological descriptions are given for each taxon, as well as a key for their identification; illustrations, photographs, or iconography; updated synonymy; geographic distribution maps and ecological notes; list of selected specimens; and discussion about the relationship among closely related taxa. A new status, C. poeppigii Walp. var. anomalum (Moldenke) N. O’Leary, and a new combination, C. dentatum D. Don var. canescens (Moldenke) N. O’Leary, are proposed. Thirty-five new synonyms are suggested, and lectotypes are designated for C. fruticosum L. var. brittonii (Moldenke) I. E. Méndez, C. laurifolium Hayek, and Rauvolfia spinosa Cav.

ABSTRACT Echimyidae (spiny rats, tree rats and the coypu) is the most diverse family of extant South American hystricognath rodents (caviomorphs). Today, they live in tropical forests (Amazonian, coastal and Andean forests), occasionally in more open xeric habitats in the Cerrado and Caatinga of northern South America, and open areas across the southern portion of the continent (Myocastor). The Quaternary fossil record of this family remains poorly studied. Here, we describe the fossil echimyids found in karst deposits from southern Tocantins, northern Brazil. The analyzed specimens are assigned to Thrichomys sp., Makalata cf. didelphoides and Proechimys sp. This is the first time that a fossil of Makalata is reported. The Pleistocene record of echimyids from this area is represented by fragmentary remains, which hinders their determination at specific levels. The data reported here contributes to the understanding of the ancient diversity of rodents of this region, evidenced until now in other groups, such as the artiodactyls, cingulates, carnivores, marsupials, and squamate reptiles.

In this contribution we present updates on the taxonomy and morphology of the South American species of Amitermes. Two new species are described: Amitermes bandeirai, sp. n., from Brazil, and Amitermes lilloi, sp. n., from Argentina. Amitermes nordestinus is a junior synonym of Amitermes aporema. The imago of A. aporema is described for the first time. Detailed comparative gut anatomy of the eight species is presented for the first time. The geographic distribution of Amitermes in South America is expanded and the distribution patterns of some species are discussed.

Three New Species

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.
