Detailed comparative anatomy of the Pinnidae (Mollusca, Bivalvia) reveals further unusual mantle specializations
Publication date: March 2020Source: Zoologischer Anzeiger, Volume 285Author(s): Jorge A. Audino, José Eduardo A.R. MarianAbstractPinnids are semi-infaunal bivalves with several unusual morphological features, some of them regarded as adaptations to environments with high concentration of suspended particles. The presence of a waste canal on the mantle wall, for example, helps rejecting surplus particles from the mantle cavity. Despite being such anatomically intriguing bivalves, detailed comparative morphology studies on pinnids are still scarce. To gain further insights into the functional anatomy of pinnids, we have tho...

Review of the genus Dinelytron Gray (Prisopodidae: Prisopodinae: Prisopodini), with a phylogenetic analysis of the genera of the Prisopodini, including the description of a new genus
Publication date: Available online 4 February 2020Source: Zoologischer AnzeigerAuthor(s): Raphael Aquino Heleodoro, José Albertino RafaelAbstractThe taxonomy of Dinelytron Gray (Prisopodidae: Prisopodinae) is controversially discussed in the literature, as well as the delimitation between Prisopodini genera. The phylogenetic relationships between Prisopodini genera were never studied. Attempting to resolve these problems, Dinelytron was reviewed and a phylogeny was conducted to test the monophyly of the genus and better delimitate the limits of the tribe genera. Resulting, Prisopoides gen. nov., with four species was desc...

Sympatric sister species with divergent morphological features of psammophilic catfishes of the south-eastern Brazilian genus Microcambeva (Siluriformes: Trichomycteridae)
Publication date: Available online 20 January 2020Source: Zoologischer AnzeigerAuthor(s): Wilson J.E. M. Costa, Paulo Vilardo, Axel M. KatzAbstractAn undescribed species of Microcambeva, a genus of small psammophilic catfishes from the Atlantic Forest of south-eastern Brazil, was found together the congener M. ribeirae inhabiting the same sand stretch of a stream, in the Rio Ribeira do Iguape basin. The new species and its sympatric congener exhibit highly divergent morphological features, but a multigene phylogeny support them as sister taxa. The new species, M. filamentosa sp. nov., is readily distinguished from all othe...

Sexual dimorphism and variability of craniomandibular morphology in the Japanese giant flying squirrel, Petaurista leucogenys (Rodentia: Sciuridae)
We examined sexual dimorphism and variability of craniomandibular morphology in the Japanese giant flying squirrel (Petaurista leucogenys) using different statistical analyses. Among 31 measurements using 33 adult skulls (19 males and 14 females), females showed slightly larger mean size for all traits. Univariate analysis revealed that females were significantly larger than males for the greatest length of skull, zygomatic breadth, and mandibular length. Discriminant functions indicated well distinctiveness between the sexes. Moreover, six additional mandibular measurements were taken for estimating the mechanical advanta...

Can a shade shed light on the monophyly of Cycloramphidae (Lissamphibia: Anura)?
Publication date: Available online 16 January 2020Source: Zoologischer AnzeigerAuthor(s): Gustavo Colaço, Gabriela Bueno Bittencourt-Silva, Helio Ricardo da SilvaAbstractWe studied the morphology, development, and the terminology of a lobe over the iris present in three genera of South American cycloramphid frogs (Cycloramphus, Thoropa, and Zachaenus). This research is based on dissections and a macroscopic survey of the eyes of tadpoles, post-metamorphosed, and adults of all six species of Thoropa, nine species of Cycloramphus (3 with adults only, and 6 with tadpoles and adults), and Zachaenus parvulus and Z. carvalhoi (...

The comparative morphology of adult pregenital abdominal ventrites and trichobothria in Pyrrhocoroidea (Hemiptera: Heteroptera: Pentatomomorpha)
Publication date: Available online 2 December 2019Source: Zoologischer AnzeigerAuthor(s): Vladimír Hemala, Petr Kment, Igor MalenovskýAbstractPyrrhocoroidea (including Largidae: Larginae, Physopeltinae, and Pyrrhocoridae) constitutes the second-smallest superfamily of the true bug infraorder Pentatomomorpha (Insecta: Hemiptera: Heteroptera). Although this group includes several taxa widely used as models in experimental studies, as well as a number of economically important pests (inc. cotton stainers), it has received very little attention from the viewpoints of comparative morphology and phylogenetics. To improve this ...

Morphology of mouthparts poorly resolves the phylogeny of Sericini chafers (Coleoptera: Scarabaeidae)
Publication date: Available online 3 December 2019Source: Zoologischer AnzeigerAuthor(s): Jujina Frings, Paul K. Lago, Dirk AhrensAbstractMorphological homogeneity within Sericini has resulted in great difficulties with respect to generic classification primarily due to lack of diagnostic characters and significant levels of homoplasy of many traits used to establish and diagnose generic groups. Recently, new morphological structures have been studied within sericines to determine their systematic utility. Reported here are the results of a comparative study of sericine mouthparts. The data gathered was used to reconstruct...

Cladistic analysis of Cnemalobus (Coleoptera: Carabidae), fossorial adaptations and description of a new species
Publication date: Available online 2 December 2019Source: Zoologischer AnzeigerAuthor(s): Sergio Roig-Juñent, Violeta Ayelen Silvestro, Germán H. CheliAbstractThe genus Cnemalobus Guérin-Ménéville can easily be distinguished from other southern South American carabids by its large number of umbilicate setae. Recent expeditions reveal the existence of a new species that has more than 170 umbilicate setae in the margin of pronotum and 180–240 in the umbilical elytral series. In addition, it has a second medial protibial tooth unique in the genus. These characters would be related to a strong fossorial adaptation by th...

The influence of locomotion and habitat use on tendo-muscular units of an anuran clade (Anura, Diphyabatrachia)
Publication date: Available online 16 November 2019Source: Zoologischer AnzeigerAuthor(s): Jéssica Fratani, María Laura Ponssa, Marco Rada, Virginia AbdalaAbstractTendons have unique mechanical properties, contributing to the transmission, amplification, and recycling of muscle energy. In this light, anuran tendons are especially interesting due to their highly mechanically demanding locomotor modes. Herein we aim to investigate the relation between tendons and muscles from two perspectives: (1) the tendinous area in relation to the potential force produced by associated muscles, and how this relation varies for differen...

Delimiting species of water mites of the genus Hydrodroma (Acari: Hydrachnidiae: Hydrodromidae) from North America and Europe: integrative evidence of species status from COI sequences and morphology
In this study, we use multiple statistical approaches, including Automatic Barcode Gap Discovery (ABGD), K2P distances, Neighbor-Joining (NJ) clustering and statistical parsimony (SP) based on mitochondrial cytochrome c oxidase subunit I (COI), and morphology to explore diversity among Hydrodroma species from North America and Europe. The results of ABGD confirmed species status of H. despiciens.(Müller, 1776), H. pilosa Besseling, 1940, H. torrenticola (Walter, 1908) from Europe and identified three species-level taxa from Canada, here provisionally called Hydrodroma sp. A, Hydrodroma sp. B and Hydrodroma sp. C. This out...
