Estimating phenotypic heritability of sexual and unisexually reproducing rock lizards (genus Darevskia)
Publication date: Available online 21 February 2020Source: Zoologischer AnzeigerAuthor(s): D. Tarkhnishvili, N. Barateli, M. Murtskhvaladze, G. IankoshviliAbstractThe difference between phenotypic and genotypic differentiation of conspecific populations is commonly used for detecting natural selection. However, phenotypic variation integrates both genetic and non-genetic components, and this may lead researchers to false conclusions. To avoid bias, the analysis of the heritability of individual phenotypic characters is important, but the means are labor–intensive and require controlled crosses. In this paper, we trie...

Cocoons of cuckoo wasps (Hymenoptera: Chrysididae): first overview of morphology reveals unexpected traces of taxonomy
Publication date: Available online 19 February 2020Source: Zoologischer AnzeigerAuthor(s): Kateryna V. MartynovaAbstractCocoons of cuckoo wasps (Hymenoptera: Chrysididae) are complex and diverse formations. They usually bear various specific structures: patches, coverings, arches, coasters, pores, nipples, internal discs and transverse opercula. These are named and thoroughly described for the first time in this contribution. Presence of specific structures distinguishes cuckoo wasps of different genera and species-groups, while species can be differentiated by location, shape and appearance of these characteristic formati...

Here, we investigate the morphology of the first-instar larva of the two-tailed hanging-fly Bicaubittacus longiprocessus (Huang and Hua, 2005) using light and scanning electron microscopy. The larva is eruciform and possesses three pairs of thoracic legs and eight pairs of abdominal prolegs. The head bears a median ocellus on the frons and a pair of compound eyes with sev...

Population history of a social spider reveals connection between South American tropical forests
In this study we investigated the population history of A. eximius using a spatiotemporal framework. Focusing on biogeographic history, we used sequences of the mitochondrial gene cytochrome oxidase subunit I (COI), to investigate population structure, diversity and time to the most recent common ancestor of the sampled individuals. We aimed to generate ecological niche models to estimate the distribution of the species from the last interglacial to the present. Our results revealed three major clusters in A. eximius (Trans-Andean, Cis-Andean, and French Guiana-Brazil) sharing common ancestors in the Late Pleistocene, c.a....

Similar to many Termitidae, this species contains a mixed segment in the intestine, an anatomic distinct region composed of both mesenteric and proctodeal tissues. In Neocapritermes spp., a pair of intestinal protrusions referred to as mesenteric sacs are associated with the mixed segment. In the present study, with the aid of ...

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 ha...

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 wa...

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...
