A taxonomic review of the marine littoral genus Iotarphia Cameron is presented. Three species are recognized, one of which is described as a new species (I. magna Song & Ahn, sp. n.) based on morphological and molecular characters. Genetic divergence of COI using uncorrected p-distance among Iotarphia species ranged from 10% to 11.6%, while intraspecific divergence ranged from 0% to 1.3%. All three species were strongly supported as a single lineage on both neighbor-joining and parsimony trees. The genus Iotarphia and I. australis Cameron are redescribed with illustrations of diagnostic characters. The female of I. rufobrunnea is characterized for the first time. A key and comparison table for similarities and differences among the species are presented.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

A taxonomic review of species and intraspecific taxa of the Astragalus L. section Helmia Bunge is presented. We treat the section Helmia in a traditional, narrow scope, including only 9 species and subspecies: A. helmii Fisch. ex DC., A. tergeminus (Knjaz., Kulikov et E. G. Philippov) Knjaz., A. permiensis C. A. Mey. ex Rupr., A. depauperatus Ledeb. (= A. chakassiensis Polozhij), A. kasachstanicus Golosk. subsp. kasachstanicus, A. kasachstanicus subsp. coloratus Knjaz., A. gregorii B. Fedtsch. et Basil. (= A. tuvinicus Timokhina), A. heptapotamicus Sumnev., A. ionae Palib. ex Gontsch. et Popov. With regard to the other 16 species of sect. Helmia in its widest sense, as accepted in the monograph by D. Podlech and Sh. Zarre (2013), we believe it more correct to attribute them to other sections. The rank of A. helmii var. tergeminus Knjaz., Kulikov et E. G. Philippov is raised to the species, A. tergeminus (Knjaz., Kulikov et E. G. Philippov) Knjaz. It is shown that A. gregorii is a priority name of A. tuvinicus. The epitype of A. permiensis C. A. Mey. ex Rupr. is designated. An identification key and a map of distribution for all species and subspecies of Astragalus sect. Helmia are presented.

Generic boundaries of the South American species Panicum longipedicellatum Swallen are explored and compared with allied genera of the tribe Paniceae. On the basis of morphological, anatomical, and molecular characters a new genus, Cnidochloa Zuloaga, is proposed. The phylogenetic position of the new genus within the Paniceae is evaluated.

The family Myriangiaceae is relatively poorly known amongst the Dothideomycetes and includes genera which are saprobic, epiphytic and parasitic on the bark, leaves and branches of various plants. The family has not undergone any recent revision, however, molecular data has shown it to be a well-resolved family closely linked to Elsinoaceae in Myriangiales. Both morphological and molecular characters indicate that Elsinoaceae differs from Myriangiaceae. In Elsinoaceae, small numbers of asci form in locules in light coloured pseudostromata, which form typical scab-like blemishes on leaf or fruit surfaces. The coelomycetous, “Sphaceloma”-like asexual state of Elsinoaceae, form more frequently than the sexual state; conidiogenesis is phialidic and conidia are 1-celled and hyaline. In Myriangiaceae, locules with single asci are scattered in a superficial, coriaceous to sub-carbonaceous, black ascostromata and do not form scab-like blemishes. No asexual state is known. In this study, we revisit the family Myriangiaceae, and accept ten genera, providing descriptions and discussion on the generic types of Anhellia, Ascostratum, Butleria, Dictyocyclus, Diplotheca, Eurytheca, Hemimyriangium, Micularia, Myriangium and Zukaliopsis. The genera of Myriangiaceae are compared and contrasted. Myriangium duriaei is the type species of the family, while Diplotheca is similar and may possibly be congeneric. The placement of Anhellia in Myriangiaceae is supported by morphological and molecular data. Because of similarities with Myriangium, Ascostratum (A. insigne), Butleria (B. inaghatahani), Dictyocyclus (D. hydrangea), Eurytheca (E. trinitensis), Hemimyriangium (H. betulae), Micularia (M. merremiae) and Zukaliopsis (Z. amazonica) are placed in Myriangiaceae. Molecular sequence data from fresh collections is required to confirm the relationships and placement of the genera in this family.
