AbstractAmong Permian smaller foraminifers, the genus Dagmarita is one of the most studied due to its worldwide distribution. The detailed study of the Zal (NW Iran) and Abadeh (Central Iran) stratigraphic sections led to redescription of the genus Dagmarita and its taxonomic composition. In Dagmarita, a peculiar generic morphological character, represented by a secondary valvular projection, has been detected for the first time among globivalvulinid foraminifers. The phylogeny of Dagmarita, and in particular its ancestor Sengoerina, is discussed and the new species, D. ghorbanii n. sp. and D. zalensis n. sp., are introduced. Analogies and differences among all the species belonging to Dagmarita are highlighted and morphological features of the new taxa are shown in 3D reconstructions, useful for understanding differently oriented sections of the specimens in thin section.UUID: http://zoobank.org/3d8eb14c-7757-4cbd-877c-4bacd2d156da

The Captorhinomorpha consists of two families, the Captorhinidae and the Protorothyrididae. The distribution of morphological character states of the skeleton permits reevaluation of currently accepted theories of the relationships of captorhinomorph reptiles. Identification of characters states that are primitive for reptiles (amniotes) has been made through outgroup comparison. The Captorhinidae, Protorothyrididae, and Diapsida form a natural group that share such derived characters as reduced supratemporal, reduced tabular, narrow supraoccipital with anteriorly directed crista alaris, loss of supratemporal–postorbital contact, loss of opisthotic–tabular contact, and loss of the medial centralia pedis. These shared derived character states indicate that captorhinomorphs are not the sister taxon of all other reptiles but are advanced relative to pelycosaurs, pareiasaurs, and procolophonids. Protorothyridids share with diapsids such derived characters as short postorbital region of the skull, keeled anterior presacral pleurocentra, slender limbs, and long, slender feet. This distribution of character states indicates that protorothyridids are more closely related to diapsids than either of these taxa is to captorhinids.The morphological pattern of small, lightly built, agile insectivores, represented by protorothyridids and early diapsids, is no longer considered to be the primitive amniote condition. Available evidence indicates that the most primitive amniote adaptation was, instead, that of a small, relatively slow carnivore that probably fed on primitive, terrestrial annelids and arthropods.

Osmanthus (Oleaceae) is considered one of the most confusing genera with regards to circumscription and phylogenetic placement of taxa within the subtribe Oleinae of Oleaceae, with controversies mainly focused on the attribution of section Leiolea. In the present study, we analyzed 71 samples that represent the broad taxonomic, biogeographic, and morphological patterns in the subtribe Oleinae. Based on concatenation of four plastid genes (trnL-F, trnT-L, trnS-G, and matK) and comparison with the ITS region, Bayesian Inference, Maximum Likelihood and Maximum Parsimony phylogenies were inferred. Morphological character traits and geographical distributions of taxa were also studied. These results provide strong support for the segregation of the Leiolea clade (Osmanthus marginatus, O. matsumuranus and O. minor) of sect. Leiolea from Osmanthus. Therefore, the Leiolea clade is instated as the new genus Chengiodendron, with a taxonomic treatment provided. This study provides a clearer understanding of the phylogenetic relationships of genera in the subtribe Oleinae.
