A new scarab beetle genus and species, Puelchesia gracilis, is described based on specimens collected in the Monte biogeographic province of west central Argentina. This genus is placed in the tribe Pachydemini based on an evaluation of the characters within the context of the current classification of the subfamily Melolonthinae. The distribution and natural history of the taxon is also discussed.

The taxonomic status of Metrosideros queenslandica, and related species from New Guinea, is reassessed on the basis of fundamental morphological and anatomical characters and these species are found to be more closely allied to Tristanin sens. str. than to Metrosideros sens. lat. The current classification of this group of species as Metrosideros subg. Mearnsia sect. Adnatae J. W. Dawson is rejected and a new genus, Thaleropia, is described and the new combinations T. queeirslandica, T. iteophylla and T. hypargyrea made.

An unusual new genus of Scenopinidae is described and figured from Namibia. Cyrtosathe kirkspriggsi gen. et sp. nov., represents the first record of a non-scenopinine window fly from subSaharan Africa. This monotypic genus does not fit well into the current classification of Scenopinidae and is likely an intermediate form between the subfamilies Proratinae and Scenopininae. The phylogenetic position of Cyrtosathe kirkspriggsi gen. et sp. nov. is discussed with respect to previous studies on Scenopinidae relationships and classification.

The current classification ofPristoceradoes not have taxonomic or cladistic support, which results in mistakes during the allocation of its species, especially within the generaDicrogenium,Kathepyris,NeodicrogeniumandDiepyris. This study aimed to verify the monophyly and to present a cladistic hypothesis for the genus. The analyses were based on 147 characters of 50 terminal taxa. Parsimony analyses under both equal and implied weightings were performed. All cladograms obtained by the implied weighting recoveredPristoceraand all four related genera as polyphyletic. A monophyletic group withPristoceraand the other genera of the inner group was formed. This group was supported by 13 synapomorphies, with one of them exclusive, as follows: the presence of a hypopygium that was divided into two parts. Based on our results, the following new genus-group synonyms were established:Dicrogenium,Kathepyris,NeodicrogeniumandDiepyrissyn.n. forPristocera, and their 39 species were combined with the latter. The following new names are proposed to avoid homonyms:Pristocera zatanom.n. forDicrogenium bequaertiBenoit,Pristocera zelanom.n. forKathepyris katangensisBenoit,Pristocera zinticanom.n. forKathepyris uelensisBenoit,Pristocera zontanom.n. forNeodicrogenium bequaertiBenoit andPristocera zuncranom.n. forNeodicrogenium tuberculatum(Turner). Therefore,Pristoceranow comprises 124 species from the Old World.

 Recent molecular phylogenies of the Lepidoziaceae indicate that the current classification is incongruent with the phylogeny. Although substantial uncertainties remain, an interim classification is needed. The classification proposed includes a broader definition of the Lembidioideae, reinstatement of Neolepidozia and Tricholepidozia and the recognition of the new genus Ceramanus. While the Zoopsidoideae are unlikely to represent a monophyletic group, it is not yet possible to provide a phylogenetically accurate revision of this subfamily.

Abstract Background Commelinaceae (Commelinales) comprise 41 genera and are widely distributed in both the Old and New Worlds, except in Europe. The relationships among genera in this family have been suggested in several morphological and molecular studies. However, it is difficult to explain their relationships due to high morphological variations and low support values. Currently, many researchers have been using complete chloroplast genome data for inferring the evolution of land plants. In this study, we completed 15 new plastid genome sequences of subfamily Commelinoideae using the Mi-seq platform. We utilized genome data to reveal the structural variations and reconstruct the problematic positions of genera for the first time. Results All examined species of Commelinoideae have three pseudogenes (accD, rpoA, and ycf15), and the former two might be a synapomorphy within Commelinales. Only four species in tribe Commelineae presented IR expansion, which affected duplication of the rpl22 gene. We identified inversions that range from approximately 3 to 15 kb in four taxa (Amischotolype, Belosynapsis, Murdannia, and Streptolirion). The phylogenetic analysis using 77 chloroplast protein-coding genes with maximum parsimony, maximum likelihood, and Bayesian inference suggests that Palisota is most closely related to tribe Commelineae, supported by high support values. This result differs significantly from the current classification of Commelinaceae. Also, we resolved the unclear position of Streptoliriinae and the monophyly of Dichorisandrinae. Among the ten CDS (ndhH, rpoC2, ndhA, rps3, ndhG, ndhD, ccsA, ndhF, matK, and ycf1), which have high nucleotide diversity values (Pi > 0.045) and over 500 bp length, four CDS (ndhH, rpoC2, matK, and ycf1) show that they are congruent with the topology derived from 77 chloroplast protein-coding genes. Conclusions In this study, we provide detailed information on the 15 complete plastid genomes of Commelinoideae taxa. We identified characteristic pseudogenes and nucleotide diversity, which can be used to infer the family evolutionary history. Also, further research is needed to revise the position of Palisota in the current classification of Commelinaceae.

Controversial Aspect

Hemocytes, the cells present in the hemolymph of insects and other invertebrates, perform several physiological functions, including innate immunity. The current classification of hemocyte types is based mostly on morphological features; however, divergences have emerged among specialists in triatomines, the insect vectors of Chagas’ disease (Hemiptera: Reduviidae). Here, we have combined technical approaches in order to characterize the hemocytes from fifth instar nymphs of the triatomine Dipetalogaster maxima. Moreover, in this work we describe, for the first time, the ultrastructural features of D. maxima hemocytes. Using phase contrast microscopy of fresh preparations, five hemocyte populations were identified and further characterized by immunofluorescence, flow cytometry and transmission electron microscopy. The plasmatocytes and the granulocytes were the most abundant cell types, although prohemocytes, adipohemocytes and oenocytes were also found. This work sheds light on a controversial aspect of triatomine cell biology and physiology setting the basis for future in-depth studies directed to address hemocyte classification using non-microscopy-based markers.
