Abstract:
Apostolepis is a diverse neotropical snake genus, which has been historically subjected to poor taxonomic descriptions, largely based on either a small type series or subjective diagnoses. We evaluate the case of Apostolepisbarrioi Lema, 1978 and its intricate taxonomic history, suggesting its synonymization with Apostolepisdimidiata (Jan, 1862), and providing brief commentary on the taxonomic instability that has been plaguing the genus.

Abstract:
AbstractIn this note, I discuss the advantages of the usage of subgenera as a practical taxonomic rank in mammalian taxonomy. Use of this category preserves traditional usage, reduces nomenclatural instability and avoids unnecessary change of names. Subgenera are useful to label diagnosable clades of closely related species, especially in morphologically and ecologically diverse monophyletic genera, without alteration of traditional binomial usage. Contrary to informal names such as “divisions” or “groups”, subgenera are governed by the rules of the International Commission on Zoological Nomenclature (ICZN), having usage constrained (and stability promoted) by typification and priority.

Abstract:
Japanese cedar [Cryptomeria japonica (Thun. ex L.f.) D. Don. (Taxodiaceae)] cultivars have become quite popular in the U.S. landscape and nursery industries. Their popularity is expected to increase as more attractive and adaptable horticultural selections gain recognition. Taxonomic problems include an inadequate inventory of selected variants cultivated in the United States, instability of names at the infraspecific taxonomic level, poor descriptions of the cultivars, and a lack of representative specimens and identification aids to help horticulturists identify unknown specimens. A study of Cryptomeria japonica cultivated in the United States is needed to address these problems.

Abstract:
The fungal kingdom is estimated to comprise between 2.2 to 3.8 million species with only about 7% named and classified. Novel biochemical, physiological and molecular techniques have been utilized to improve the systematics of fungal taxa and estimates of their diversity. Multidisciplinary approaches should be used for resolving species and higher taxa of the fungi. However, even with all the benefits of the new techniques, they are also providing unclear results and taxonomic instability. Taxonomists should be aware of these issues and should follow pragmatic approaches. In order to overcome these taxonomic challenges, cooperation and communication among mycologists worldwide are crucial for the study of fungal diversity.

Abstract:
Aphonopelma braunshausenii Tesmoingt, 1996 is regarded as a nomen dubium due to the lack of a deposited holotype, an inadequate description which gives no stable taxonomic features to differentiate it from any other species and the absence of an exact type locality. The instability of some morphological characters which were given weight for species delineation in many earlier works is discussed and illustrated.

Abstract:
AbstractThe genera Lepidothyris, Lygosoma and Mochlus comprise the writhing or supple skinks, a group of semi-fossorial, elongate-bodied skinks distributed across the Old World Tropics. Due to their generalized morphology and lack of diagnostic characters, species- and clade-level relationships have long been debated. Recent molecular phylogenetic studies of the group have provided some clarification of species-level relationships, but a number of issues regarding higher level relationships among genera still remain. Here we present a phylogenetic estimate of relationships among species in Lygosoma, Mochlus and Lepidothyris generated by concatenated and species tree analyses of multilocus data using the most extensive taxonomic sampling of the group to date. We also use multivariate statistics to examine species and clade distributions in morpho space. Our results reject the monophyly of Lygosoma s.l., Lygosoma s.s. and Mochlus, which highlights the instability of the current taxonomic classification of the group. We, therefore, revise the taxonomy of the writhing skinks to better reflect the evolutionary history of Lygosoma s.l. by restricting Lygosoma for Southeast Asia, resurrecting the genus Riopa for a clade of Indian and Southeast Asian species, expanding the genus Mochlus to include all African species of writhing skinks and describing a new genus in Southeast Asia.

Abstract:
Although Crustacea has a long history of being recognized as a formal taxonomic group in arthropod classification, the past 30 years have witnessed repeated challenges to crustacean monophyly. Few unambiguous autapomorphic characters for crustaceans have been proposed by morphologists, and many diagnostic characters can be interpreted as symplesiomorphies of Mandibulata. More serious challenges arise from molecular phylogenetics: irrespective of the scope of taxonomic and/or character sampling or analytical methods, a pancrustacean clade in which “Crustacea” is paraphyletic with respect to Hexapoda is retrieved. However, most traditional single to multigene studies infer phylogenies that display considerable mutual conflict. Although hexapod monophyly is robust and its deep branchings have recently been recovered using large-scale transcriptomic datasets, its crustacean sister group has been contentious. To some extent, a conclusive result is still hindered by uneven taxonomic coverage, with some key groups still being undersampled in phylogenomic studies. Nonetheless, phylogenomic analyses provide some robust results: notably, Hexapoda is part of a pancrustacean clade named Allotriocarida, which includes Cephalocarida and Branchiopoda as a grade or each other’s sister group, and Remipedia as the closest relatives to Hexapoda. Neuroanatomical support for a rival malacostracan-remipede-hexapod clade is incongruent with molecular datasets, which instead group Malacostraca, Copepoda, and Cirripedia as a clade. However, cirripedes resolve either as a sister group to copepods or to malacostracans, and this instability casts doubt on the typical pattern in molecular analyses that position malacostracans unexpectedly deep within the crustacean lineage. Pancrustacean phylogeny requires critical interpretation of phylogenomic data to reveal conflict in the data and ambiguous signals within the selected set of orthologous genes.

Abstract:
Systems engineers have often paid too little attention to the nature of the so-called “users” of products under development. These are better called stakeholders, as many roles are involved, and few of those are in direct contact with the developed products. A simple and robust conceptual framework for classifying development stakeholders — a taxonomy — is proposed. The taxonomy is product centric, with concentric “circles” denoting broad categories of stakeholders. Within these, generic “slots” describe typical classes of stakeholders; these are subdivided into “roles,” which are expected to vary at least in name with the domain. Examples are given, and a popular template is reanalysed using the framework. The taxonomy has immediate value in identifying and validating stakeholder roles in requirements elicitation, helping to ensure that key viewpoints are not missed, and hence reducing the risk of instability and failure during development.

Abstract:
The sociolinguistics of language contact is known to effect levels of phonological and grammatical complexity of the languages involved, and linguistic features are known to have different levels of stability and different propensities of borrowing and diffusion. This chapter lays out basic taxonomies of demographic and geographical histories of areas, stability or instability or linguistic variables, and ages of areas, and raises hypotheses about correlations among them. Pilot studies of ten areas worldwide support the expected correlations.
