A taxonomic synopsis of Virola (Myristicaceae) is presented for Mesoamerica. Fourteen species are recognised, amongst them six are described and published as new, based on morphology: V. allenii D.Santam. & Aguilar, sp. nov. from Costa Rica, V. otobifolia D.Santam., sp. nov. from Panama and V. amistadensis D.Santam., sp. nov., V. chrysocarpa D.Santam. & Aguilar, sp. nov., V. fosteri D.Santam., sp. nov. and V. montana D.Santam., sp. nov. from both Costa Rica and Panama. Additionally, a lectotype is designated for V. koschnyi, accompanied by an epitype in view of the fragmentary material. Finally, we recognise V. laevigata and V. nobilis as morphologically distinct species, though these are frequently considered synonymys of V. guatemalensis and V. surinamensis, respectively. Of the fourteen accepted species, twelve of them are endemic to Mesoamerica, while the remaining two species (V. elongata and V. sebifera) extend into South America. Illustrations, species diagnoses and distribution maps for each species are provided, as is an identification key to all species.

Background and aims – As “islands in the sky” of northern South America, the isolated ecosystems of the Pantepui province include a distinct flora with high levels of endemism and which are ancestral areas for many angiosperm lineages. About one fifth of Pantepui angiosperm species are distributed in Poales, a highly diverse angiosperm order.Methods – Recent field trips were carried out on two Brazilian tepuis, by foot and helicopter. Herbarium collections were consulted and compared with the proposed new species. Key results – Four new species of Poales, three Navia Schult. & Schult.f. (Bromeliaceae) and one Paepalanthus Mart. (Eriocaulaceae) were found. Descriptions, illustrations, and distribution maps of the new species, as well as an identification key to Brazilian Navia species, are provided.

The wasp genus Liosphex Townes 1977 is revised and twelve new species are described: Liosphex achuar sp. nov. (Costa Rica, Ecuador, Panama and Peru), L. atratus sp. nov. (Costa Rica and Mexico), L. boreus sp. nov. (Mexico, Kentucky and Mississippi, USA), L. bribri sp. nov. (Costa Rica, Panama and Peru), L. darien sp. nov. (Panama), L. guanabara sp. nov. (Brazil), L. guarani sp. nov. (Brazil and Argentina), L. longicornis sp. nov. (Costa Rica), L. maleku sp. nov. (Costa Rica and Mexico), L. micropterus sp. nov. (southern Brazil and Paraguay), L. quechua sp. nov. (Peru), and L. tupi sp. nov. (Brazil). The male of L. trichopleurum Townes, 1977 is described for the first time. A redescription of L. varius Townes, 1977, including new diagnostic characters, is provided since the original description was based on a heterogeneous type series of specimens from different species. The revision includes images of all fourteen species, illustrations of the main diagnostic characters, an identification key to species and distribution maps for all species.

Taxonomic Descriptions

Seringia J.Gay and Keraudrenia J.Gay are widely spread in Australia, and one species occurs in Madagascar. Revision of these closely related genera suggested that neither genus is monophyletic on the basis of morphological or preliminary molecular data. As a result, Keraudrenia is subsumed into Seringia. There are now 20 species of Seringia, including the currently accepted type species Seringia platyphylla J.Gay (=Seringia arborescens (W.T.Aiton) Druce). Five new species S. adenogyna C.F.Wilkins, S. cacaobrunnea C.F.Wilkins, S. elliptica C.F.Wilkins, S. undulata C.F.Wilkins and S. saxatilis C.F.Wilkins are described. Four species of Keraudrenia initially described as Seringia and recognised as the latter by F. J. H. von Mueller are reinstated (S. adenolasia F.Muell., S. corollata Steetz, S. lanceolata Steetz, S. nephrosperma F.Muell.). Five previous combinations of Keraudrenia and Seringia as Seringia are recognised (S. hermanniifolia (J.Gay) F.Muell., S. hillii (Benth.) F.Muell., S. hookeriana (Walp.) F.Muell., S. integrifolia (Steud.) F.Muell., S. velutina (Steetz) F.Muell.) and five new combinations are made (S. collina (Domin) C.F.Wilkins & Whitlock, S. denticulata (C.T.White) C.F.Wilkins & Whitlock, S. exastia (C.F.Wilkins) C.F.Wilkins & Whitlock, S. katatona (C.F.Wilkins) C.F.Wilkins & Whitlock, S. macrantha (Baill.) C.F.Wilkins & Whitlock. Keraudrenia collina var. multiflora Domin is placed in synonymy under S. nephrosperma F.Muell. Keraudrenia corollata var. denticulata C.T.White is recognised as a distinct species, S. denticulata (C.T.White) C.F.Wilkins & Whitlock. Anatomical studies, taxonomic descriptions, distribution maps, illustrations and identification keys are presented for Seringia, and an identification key to genera of the tribe Lasiopetaleae is provided.

ABSTRACT The taxonomic revision of Amorimia (Malpighiaceae) is presented, including typifications, and descriptions for all accepted species. The genus is endemic to Seasonally Dry Tropical Forests and Rainforests of South America, and its species can be distinguished by morphological details of leaves, indumenta, inflorescences, flowers, and fruits. This study includes an identification key for the subgenera and species of Amorimia, illustrations, distribution maps, conservation risk assessments, and comments on ecology, nomenclature, and taxonomy for all species. Additionally, I provide a key to differentiate Amorimia from the remaining genera of the Malpighioid clade.

Subjective Synonym

The old genus Libitia Simon, 1879 of small Andean harvestmen is revisited. The monotypic genus Libitiella Roewer, 1947 is herein considered a junior subjective synonym of Libitia. Accordingly, Libitiella bipunctata (Sørensen, 1932) is restored to the combination Libitia bipunctata. The species Libitia cordata and Libitia bipunctata comb. nov. are redescribed and the new species Libitia gandalf sp. nov. and Libitia iguaque sp. nov. are herein described from Cordillera Oriental of Colombian Andes (Chingaza Natural Park and Iguaque Natural Park, respectively). The species Gonyleptes multimaculatus Wood 1869, currently under the synonymy of L. cordata, is revalidated and transferred to Paecilaemella Roewer, 1925 forming Paecilaemella multimaculata comb. nov., and the species Cynorta itacoaiensis H. Soares, 1970 is herein considered a junior subjective synonym of it. In addition, the second current species of the genus, Libitia fusca (Simon, 1879), is transferred to Metalibitia. Libitia is diagnosed based in genital and external morphology, an identification key of the four species and distribution maps are offered.

A New Species

AbstractCopris incertus Say, 1835 (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini) has been described as a New World coprophagous scarab distributed from Mexico to Ecuador with large discontinuities in its range between the Yucatán province and Costa Rica. The C. incertus species complex of the Copris minutus (Drury, 1773) species group consists of C. incertus, Copris laeviceps Harold, 1869, and Copris lugubris Boheman, 1858. Based on external morphology and male genitalia, we discovered that multiple species have been classified as C. incertus. Of these species, five are new: Copris amazonicusnew species, Copris brevicornisnew species, Copris davidinew species, Copris moroninew species, and Copris susanaenew species. Herein, we revise the organisation of the C. incertus species complex and propose a new species complex, the C. laeviceps species complex, which includes: C. davidi, Copris igualensis Warner, 1990, and C. laeviceps, formerly included in the C. incertus species complex. We provide an identification key along with species distribution maps, images of habitus, and diagnostic characters.

An illustrated identification key to all species of the group is provided. The Clistopyga isayae species group is composed entirely of previously undescribed species mainly from Andean forests of tropical South America.
