Integrative taxonomy: Morphology and ancient DNA barcoding reveals the true identity of Astyanax taeniatus, a tetra collected by Charles Darwin during the Beagle's voyage
In this study, in order to retrieve taxonomic data and to warrant an accurate identification for A. taeniatus henceforth, we integrated molecular and morphology data obtained from syntypes and new specimens collected in the type-locality. Additionally, information from Darwin's journal and from a Brazilian project to retrieve Darwin's travels in Brazil ("Caminhos de Darwin"), allowed to accurately locate the A. taeniatus type-locality at Conceição de Macabú municipality, northern Rio de Janeiro State. The two syntypes of T. taeniatus were examined and a tissue sample was extracted from one of them to compare genetically...

Atemelia casimiroae sp. nov. (Lepidoptera: Yponomeutoidea: Praydidae): a new pest species on white sapote (Casimiroa edulis) in California, United States, reveals unique morphology of spinneret and ventral eversible gland
Publication date: Available online 12 January 2019Source: Zoologischer AnzeigerAuthor(s): Jae-Cheon Sohn, Marc E. EpsteinAbstractA new species of Praydidae: Atemelia casimiroae sp. nov. is described from California, United States, based on adults and larvae. This species is regarded as a potential pest on white sapote, Casimiroa edulis. Rutaceae is recorded as a host plant family of Atemelia for the first time. Larval characteristics of the spinneret and ventral eversible prothoracic gland of Atemelia were observed via SEM photography. Convergence of Atemelia spinnerets to those found in Limacodidae, Dalceridae and Bombyco...

Putative mating plugs of harvestmen (Opiliones, Laniatores)
Publication date: Available online 29 December 2018Source: Zoologischer AnzeigerAuthor(s): Victor R. Townsend, Abel Pérez-González, Daniel N. ProudAbstractIn many species of scorpions (Order Scorpiones) and spiders (Order Araneae), mating plugs (gel-like or sclerotized) are deposited in the female reproductive tract, minimizing the possibilities of further matings. Although harvestmen (Order Opiliones) have direct sperm transfer via copulatory organs (penis or spermatopositor in the male and ovipositor in the female), prior studies of the reproductive anatomy of these arachnids have not reported the occurrence of these s...

The forewing of Cacopsylla mali (Schmidberger 1836) (Hemiptera, Sternorrhyncha) – a morphological and histological study
Publication date: Available online 21 December 2018Source: Zoologischer AnzeigerAuthor(s): Barbara Franielczyk-Pietyra, Piotr WegierekAbstractThe forewing surface of Cacopsylla mali (Schmidberger 1836) was examined using scanning electron microscopy. Spines and campaniform sensilla on the vein course and small spines on wing membrane cells were described. Cross-sections of the material were performed using histological methods. A two-layered membrane with convex circular or triangular foramens on the dorsal wing surface was revealed. Both, the course of veins and the places of their bifurcation were followed. Three veins, ...

The morphology of the vesica spermalis is described and the relation between the Basalis, Connata and Nigricans groups is analyzed. Erythrodiplax chromoptera is easily distinguished from the other congeners by the shape of the basal spot of the hind wing and the shape of the median process of the vesica sper...

Comparative morphology of second and third instar larvae of Palaeostigus bifoveolatus (Boheman, 1851) (Coleoptera: Staphylinidae: Scydmaeninae)
Publication date: Available online 20 December 2018Source: Zoologischer AnzeigerAuthor(s): Paweł Jałoszyński, Aleksandra KilianAbstractExoskeletal morphological structures of all extant genera currently included into Mastigitae are very well studied, whereas the larvae are poorly known. Larval morphology provides a valuable character system for phylogenetic reconstructions, and as all hitherto carried out analyses of Mastigitae were based on adult characters only, it is important to fill this major gap by studying immature stages. We here describe in detail the second- and third-instar larvae of the South African ant-li...

Notes on the morphology and histology of the ovarioles of Gerris lacustris (L.) (water strider) (Insecta: Hemiptera: Heteroptera: Gerridae)
Publication date: Available online 13 December 2018Source: Zoologischer AnzeigerAuthor(s): Nurcan Özyurt Koçakoğlu, Selami Candan, Zekiye SuludereAbstractThe morphology and histology of the female reproductive system of Gerris lacustris water strider (Linnaeus 1758) (Heteroptera: Gerridae) are described using both light and scanning electron microscopy (SEM). Based on histomorphology, the adult female reproductive system of G. lacustris consists of a pair of ovaries, a pair of lateral oviducts, a common oviduct. The ovaries are connected to a genital aperture by oviducts. Each adult ovary is composed of four telotrophic...

Is the Phasmatodea male genitalia useful for systematics? A case study in Creoxylus and Prexaspes (Insecta: Phasmatodea) from the Brazilian Amazon Basin
Publication date: Available online 2 December 2018Source: Zoologischer AnzeigerAuthor(s): Raphael Aquino Heleodoro, José Albertino RafaelAbstractThe male genitalia have been neglected in Phasmatodea studies over the years. There are few works describing and illustrating this organ and no studies demonstrating its usage. Concerned by this matter, this paper aimed to investigate whether the male genitalia of Phasmatodea is useful for systematics. First, by describing a new species of Creoxylus Audinet-Serville (C. duckei sp. nov.) and including the description of its male genitalia, along with the differentiation from the m...

On the identity of Hyla zernyi Ahl 1933 (Anura: Hylidae) from Taperinha, Pará, Brazil
Publication date: Available online 22 November 2018Source: Zoologischer AnzeigerAuthor(s): Marinus S. HoogmoedAbstractRe-examination of the holotype of Hyla zernyi showed it to be a recently metamorphosed juvenile of Dryaderces inframaculata, and not a synonym of Trachycephalus typhonius, a species with which it had been incorrectly synonymized in 1971. Synonymization of H. zernyi with D. inframaculata was only possible after juveniles of D. inframaculata were collected recently in an area relatively close to the type locality of H. zernyi in Brazilian Amazonia near Santarém. Examination of the holotype of Hyla auraria sh...

Communication, behaviour, and decision making in crayfish: A review
Publication date: Available online 9 November 2018Source: Zoologischer AnzeigerAuthor(s): Jan Kubec, Antonín Kouba, Miloš BuřičAbstractAnimals exhibit behavioural patterns characterized by responses to information received from internal and external stimuli. The ultimate response or decision is based on physical, chemical, or biological factors and their analysis by the nervous system, and may be influenced by previous experiences, stressors, and limitations. This review summarizes behavioural patterns connected with decision making in crayfish, and includes similarities to vertebrates and other invertebrates that may ...
