TL;DR: Parsimony analyses of the molecular data base indicate that Surianaceae sensu Cronquist are paraphyletic; inclusion of Recchia rendered the family monophyletic, and suggest that the affinities of Surian Families lie in a clade comprising at least Polygalaceae, Fabaceae, andQuillaja.
Abstract: Sequence data for the rbcL locus were obtained for two of the three species of the Mexican endemicRecchia. Parsimony analyses of the molecular data base indicate that Surianaceae sensu Cronquist are paraphyletic; inclusion ofRecchia rendered the family monophyletic. This placement is corroborated by a suite of morphological characters: an apocarpous (or monocarpic), gynoecium of bi-ovulate carpels with basal-marginal placentation and a ventrobasal style, and the occurrence in all butGuilfoylia of a characteristic 3-layered endocarp. The molecular data support a closer relationship betweenRecchia and the AustralianCadellia than between the latter and any of the other Australian genera. The molecular data suggest that the affinities of Surianaceae lie in a clade comprising at least Polygalaceae, Fabaceae, andQuillaja.
TL;DR: The pollen morphology of Quillajaceae has more in common with that of Leguminosae and Surianaceae, and with Cadellia in particular, than with Polygalaceae, while that of Stylobasium and Suriana are morphologically similar.
TL;DR: Recchia simplicifolia, a new species from southern Veracruz, southern Tabasco and northern Chiapas, represents the first non-microphyllous simple-leaved New World species of Simaroubaceae, supporting the hypothesis of exchange between the wet and dry Mexican floras during the climatic cycles of the Pleistocene.
Abstract: Recchia simplicifolia, a new species from southern Veracruz, southern Tabasco and northern Chiapas, represents the first non-microphyllous simple-leaved New World species of Simaroubaceae. It differs from the other two species of Recchia in its simple leaves, cauliflory, and rain forest habitat. Its discovery may necessitate a reevaluation of the relationships of Surianaceae and Simaroubaceae. Although its distribution corresponds to a high-precipitation area which demonstrates strong affinities to the wet Central American flora and may have served as a refuge area for rain forest species during parts of the Pleistocene, its relationships are strictly with Mexican species of the dry Pacific slope, supporting the hypothesis of exchange between the wet and dry Mexican floras during the climatic cycles of the Pleistocene.
TL;DR: Four new species of Cerambycidae are described from Paraguay: Eranina tomentilla (Hemilophini), Mimasyngenes concolor (Desmiphorini), Recchia drechseli (Aerenicini); and Microibidion bimaculatum (Neoibidioini).
Abstract: Four new species of Cerambycidae are described from Paraguay: Eranina tomentilla (Hemilophini); Mi- masyngenes concolor (Desmiphorini); Recchia drechseli (Aerenicini); and Microibidion bimaculatum (Neoi- bidionini). The new species are included in known keys.
TL;DR: Antodice eccentrica, sp. n. and A. eryhronota Lane, 1970, transferred to Apagomerina, Gilmour, 1962, Trichohippopsides Breuning, 1980 (originally described in Agapanthiini) = Recchia Lane, 1966; Trichhoppersides albicans Breuning 1980 = R. albica (GuerinMeneville, 1844) is recorded for Argentina (Salta).
Abstract: New species described: Antodice eccentrica, sp. n. and A. suturalis, sp. n., from Ecuador; Apagomerina, rubricollis, sp. n., from Brazil. New synonyms proposed: Xenonta Lane, 1970 (originally included in Hemilophini) = Apagomerina, Gilmour, 1962; Trichohippopsides Breuning, 1980 (originally described in Agapanthiini) = Recchia Lane, 1966; Trichohippopsides albicans Breuning, 1980 = Recchia albicans (GuerinMeneville, 1844). The type species of Xenonta, X. eryhronota Lane, 1970, is transferred to Apagomerina. Mariliana ocularis (Hope, 1846) is recorded for Argentina (Salta).
