BACKGROUND: Dermal melanocytic neoplasms are common in some even-toed ungulates (Artiodactyla), yet this entity has not been reported in the pygmy hippopotamus to date. Concurrent occurrence of multiple benign and malignant melanocytic neoplasms is unusual. Malignant transformation occurs in a small percentage of benign melanocytic tumours in people but this phenomenon has not been well documented in animals. OBJECTIVES: To report the diagnosis and treatment of concurrent dermal melanocytomas and malignant melanomas in a pygmy hippopotamus...

F Gary Stiles, Vitor DE Q Piacentini, J V Remsen
The generic classification of the Trochilidae is unusually complicated because early authors, faced with a deluge of specimens with little or no data, often based species and genus names on superficial plumage characters derived from figured plates of varying artistic quality and reproduction. Working independently and with little knowledge of species distributions and with the fixation of type species for genera inconsistent or ignored, these authors produced a bewildering array of generic synonyms. The generic nomenclature of the largest and most recently derived clade of hummingbirds, the tribe Trochilini or "emeralds", presents an unusually tangled web...

Discussions of current issues of broad interest in zoological taxonomy are encouraged in Zootaxa (Zhang 2007). One recent topic examines species names based on photographs without preserved specimens. This is not a new topic: as Ceríaco et al. (2016) correctly noted, this topic was previously discussed about a decade ago in Zootaxa (Dubois & Nemésio 2007; Donegan 2008), and was soon followed by a series of opinions and rebuttals when the critically endangered species Galápagos pink land iguana-Conolophus marthae Gentile & Snell, 2009-was named without a preserved holotype (Donegan 2009; Nemésio 2009a,b; Dubois 2009; Gentile & Snell 2009; Minelli 2009)...

The work of Meigen 1800 was suppressed by the ICZN Commission in 1963 for the purposes of zoological nomenclature. The work as such is still to be treated as having been published and it remains available as a source of published descriptions and illustrations. Therefore, while the names in Meigen (1800) are deemed unavailable, a subsequent usage of any of the names may be considered a novel proposal. We review the first post-Meigen 1800 occurrence of each name, its first date of availability and authorship, and determine status and synonymy...

Since the catalogue of Buprestoidea was published (Bellamy, 2008-2009) we have been adding new taxa into the printed copy in the National Museum, Prague. During this work we have found some questionable descriptions which were published in the electronic publication "Procrustomachia" which has no official status and does not meet the requirements for the publication of scientific names in zoology; the names published in this way are unavailable according to the Code (ICZN, 1999, 2012). The situation is discussed in the following text...

A recent series of papers, and rebuttals, regarding Photography-based taxonomy (PBT) (Pape et al. 2016, Krell et al. 2016, Ceríaco et al. 2016, Thorpe 2017) has raised much controversy and discussion about the practice of describing new species without preserved type specimens. Although there has been thoughtful discussion upon this issue, there is still much misunderstanding, especially regarding the idea of changing parts of the International Code of Zoological Nomenclature (ICZN 1999) to regulate this practice...

Wolfgang Zeidler
The generic name Euscelus was originally proposed by Schoenherr (1833: 205) for a genus of Leaf Rolling weevils (Insecta: Coleoptera: Attelabidae). It is a valid name, in current use, for a relatively large genus of weevils, widespread in northern South America and central America, including the West Indies and the Caribbean (e.g. Hamilton 2007; Legalov 2007). Euscelus Claus, 1879 was established as a monotypic genus of pelagic amphipod (Crustacea: Amphipoda: Hyperiidea: Parascelidae). It is a very rare genus, still monotypic, with the only species, E...

BACKGROUND: In a recent paper, we described a new sponge species named Hemimycale mediterranea Uriz, Garate & Agell, 2017. However, we failed to designate a holotype and a type locality, as required by the International Commission on Zoological Nomenclature (ICZN). Although the validity of the previous conclusions remains unchanged, the species name cannot be considered available according to ICZN regulations until a holotype is designated. RESULTS: The present work fulfills the requirements of the ICZN by designating a holotype, three paratypes and the type locality for the new species Hemimycale mediterranea and has been registered in ZooBank...

ETHNOPHARMACOLOGICAL RELEVANCE: Bhutan has two traditional healing systems: a folklore medicine and the Bhutanese Sowa Rigpa medicine (BSM). Three different types of ingredients namely plants, animals (and their derived products) and minerals are used for the preparation of various formulations in combined form. Animals and their derived products are vital ingredients in the preparation of numerous traditional remedies. Unlike medicinal plants, research on medicinal animals has remained largely untouched...

The recently discovered variegated squirrel bornavirus 1 (VSBV-1) caused the death of three squirrel breeders in Germany. Subsequent first screening of squirrels with in vivo collected swab samples and a VSBV-1-specific RT-qPCR revealed not only variegated squirrel infections (Sciurus variegatoides), but also Prevost's squirrels (Callosciurus prevostii) as positive for VSBV-1 genome. In this study, 328 squirrels were tested using the established RT-qPCR assays. In 16 individual animals VSBV-1 RNA could be detected; 15 individuals were from small breedings and zoological gardens in Germany, with the remaining individual being from a zoological garden in Croatia...

In the last years, studies on captive greater flamingos have increased. Research on zoo animals is important to improve the knowledge on these species and to improve their ex-situ and in-situ conservation. The aim of the present study was to investigate the parental behaviour of a captive colony of greater flamingo hosted at Parco Natura Viva, an Italian zoological garden, to improve the knowledge on this species in zoos. In particular, the present study investigated and compared the parental care of females and males in 35 breeding pairs of greater flamingos...

Intensely eosinophilic and glassy intracytoplasmic inclusions were present in the neurons of the peripheral autonomic ganglia, Meissner's and Auerbach's plexus, and spinal ganglia in 20 aged white-nosed coatis ( Nasua narica, 7-19 years old) and in 4 of 7 brown-nosed coatis ( Nasua nasua, 2-21 years old) from multiple zoological institutions. Inclusions were single to numerous, sometimes distorting the cell. Pheochromocytomas were present in 5 of 16 white-nosed and 2 of 6 brown-nosed coatis, although no inclusions were present in the adrenal glands...

James L Gutmann
The use of microscopes in dentistry has become quite popular since the late 1980s. However, its origin for dental applications can be traced to the early 20th century, when a microscope, invented by an American biologist named Greenough, working in the Zeiss Company, was adapted for use in dentistry. Initially it had been used in botany, metallurgy, and zoology, in addition to revolutionizing the study of coral and entomology.

It is the central thesis of this paper that the "biological perspective" (Lynn Nyhart) typical for Germany, with its interest in living animals, not only influenced natural history practices in many ways during the second half of the 19th century, rather also shaped the illustrations of popular zoology publications, as for example those in Brehms Thierleben. The illustrators of this period preferred to use live animals as models, which they studied in zoos. These animals were often depicted in their "natural" habitats...

Advanced reproductive technologies (ART's) are often employed with various taxa to enhance captive breeding programs and maintain genetic diversity. Perivitelline membrane-bound (PVM-bound) sperm detection has previously been demonstrated in avian and chelonian species as a useful technique for breeding management. In the absence of embryotic development within an egg, this technique can detect the presence of sperm trapped on the oocyte membrane confirming breeding, male reproductive status, and pair compatibility...

Animal welfare monitoring is an essential part of zoo management and a legal requirement in many countries. Historically, a variety of welfare audits have been proposed to assist zoo managers. Unfortunately, there are a number of issues with these assessments, including lack of species information, validated tests and the overall complexity of these audits which make them difficult to implement in practice. The animal welfare assessment grid (AWAG) has previously been proposed as an animal welfare monitoring tool for animals used in research programmes...
