Increasing our knowledge on direct-developing frogs: the ontogeny of Ischnocnema henselii (Anura: Brachycephalidae)
Publication date: Available online 14 November 2019Source: Zoologischer AnzeigerAuthor(s): Javier Goldberg, Pedro P.G. Taucce, Silvia Inés Quinzio, Célio F.B. Haddad, Florencia Vera CandiotiAbstractDue to the difficulty in finding newly fresh spawn in natural environments, few embryonic developmental studies have been carried out in anurans with direct development. Here we provide detailed data on the embryonic ontogeny of Ischnocnema henselii, and compare some morphological aspects related to its developmental mode within and outside of the brachycephaloid clade. Embryonic development in I. henselii is characterized by ...

Female sexual maturity as a determining factor of size-assortative pairing in the protandrous spider Manogea porracea (Araneae, Araneidae)
Publication date: Available online 15 November 2019Source: Zoologischer AnzeigerAuthor(s): Rafael Rios Moura, João Vasconcellos-Neto, Marcelo Oliveira GonzagaAbstractProtandry occurs when males mature prior to females in the breeding season. There may be a fitness benefit for males if they are able to copulate and defend virgin and more fecund females. Therefore, fitness benefits can be investigated by studying assortative mating during mate guarding of virgin females before and after female sexual maturation. The asynchrony of female development in the protandrous spider Manogea porracea (Araneidae) provides an opportuni...

Middle East Caridina (Decapoda: Atyidae): Redescription of C. fossarum Heller, 1862, description of three new species, and remarks on the status of C. syriaca Bouvier, 1904 and C. babaulti basrensis Al-Adhub & Hamzah, 1987
Publication date: November 2019Source: Zoologischer Anzeiger, Volume 283Author(s): Werner Klotz, Thomas von Rintelen, Magdalini ChristodoulouAbstractThe most species-rich genus, Caridina, of the shrimp family Atyidae is broadly distributed throughout five biogeographic realms, with the Indo-Malayan realm being the centre of its distributional range. Due to the scarcity of studies, very little is known regarding the Middle East species, which are placed on the north-western edge of the genus’ distribution. Numerous museum specimens from across the entire range of Caridina in the Middle East were thus analysed using morpho...

Antennal sensilla in male gall-wasps (Hymenoptera: Cynipidae) and insights on the evolution of sexual dimorphism in cynipoid sensory equipment
Publication date: Available online 23 October 2019Source: Zoologischer AnzeigerAuthor(s): Alberto Jorge, Carlo Polidori, José L. Nieves-AldreyAbstractThe diversity of insect antennal structures involved in communication is still poorly known because of the limited number of comparative studies and as such studies often exclusively focus on one sex. Within Cynipoidea, a recent study on female gall-wasps (Hymenoptera: Cynipidae) and some of their non-gall associated relatives (Ibaliidae and Figitidae) showed a great diversity of the antennal sensillar equipment both between and within lineages. In order to better understand...

Interspecific larvae competence and mandible shape disparity in cutworm pest complex (Lepidoptera: Noctuidae)
In this study, we analyze whether the shape of the mandibles is a contrasting trait between seven cutworm species, and we discuss whether this morphological trait can be an influential factor in the abundance and predominance of species within the complex between the southern and northern part of the Pampean region. Using geometric morphometrics tools, the results evidenced that cutworms complex differs in this functional trait. Closer phylogenetically species of Agrotis were widely different between them, while species phylogenetically distant belonging to Feltia and Peridroma were lightly similar. These results showed th...

Comparative morphometric analysis of petioles and forewings of the European Binodoxys Mackauer species (Hymenoptera: Braconidae: Aphidiinae)
Publication date: Available online 22 October 2019Source: Zoologischer AnzeigerAuthor(s): Maja Lazarević, Saša S. Stanković, Andjeljko Petrović, Marijana Ilić Milošević, Željko Tomanović, Ana Ivanović, Vladimir ŽikićAbstractThe European fauna of Aphidiinae comprises eight species of the genus Binodoxys Mackauer, which are traditionally assigned into two morphologically distinguished groups: “acalephae” and “angelicae” morpho-groups. Here, we explored the genetic variation (based on the phylogenetic reconstruction using the barcoding COI region) and tested whether the morphological variation based on the...

High genetic diversity in an invasive freshwater fish species, Carassius gibelio, suggests establishment success at the frontier between native and invasive ranges
Publication date: Available online 18 October 2019Source: Zoologischer AnzeigerAuthor(s): Sevan Ağdamar, Ali Serhan TarkanAbstractNon-native freshwater fish introductions can have direct and indirect negative effects on native flora and fauna, ecosystems, and national economies. Although invasions are paradoxical from an evolutionary standpoint, population genetics could be useful to understand invasion scenarios of non-native species. One of the most common introduced fish in Europe and Turkey is the gibel carp Carassius gibelio, which was first introduced from East Asia in the 17th century. To find out the origin and di...

Two new species of Neotropical land flatworms (Platyhelminthes: Continenticola) occurring in ferruginous and limestone caves
Publication date: Available online 10 October 2019Source: Zoologischer AnzeigerAuthor(s): Silvana Vargas do Amaral, Ana Maria Leal-Zanchet, Rodrigo Lopes FerreiraAbstractCompared to epigean domains, subterranean natural cavities are relatively stable environments. Among other invertebrates, land planarians have been sampled from caves in the Neotropical region, where their diversity seems to be high, but almost unknown. Besides being photophobic, land flatworms depend on the moisture of their microhabitats, since they do not have water-saving adaptations and, thus, caves seem to be an appropriate refuge for them. In the pr...

Fat body morphology, but not body size, changes in forager bees of Scaptotrigona jujuyensis (Apidae: Meliponini) during foraging season
Publication date: Available online 27 September 2019Source: Zoologischer AnzeigerAuthor(s): L. Galvani Gerónimo, M. Soto Eduardo, E. Canavoso Lilian, P. Settembrini BeatrizAbstractThe morphological variation of workers is a phenomenon related to a colony context. We have studied body size and fat body morphology in foragers of Scaptotrigona jujuyensis during different periods of the foraging season. In workers which forage at the start of season the number of oenocytes was lower than that of the remaining groups. Cytological analyses of trophocytes revealed that the granules differed in the staining pattern according to t...

Comparative skull morphometrics of three sympatric opossums (genus Didelphis)
Publication date: Available online 23 September 2019Source: Zoologischer AnzeigerAuthor(s): Erick I. Bustamante, M. Amelia ChemisquyAbstractMarsupials of the genus Didelphis are an interesting model to study morphological variation, since they show constant growth throughout their life, and have a wide distribution. Having samples narrowed down in time and space gave us an opportunity to study intra-population variation, therefore having a starting point to study the variability of a species. Our aims are: to analyze the intra-population variation of D. albiventris, D. aurita, and D. marsupialis using specimens collected i...

Comparative morphology of sensilla on the antennae, maxillary and labial palps in different larval instars of Cryptorrhynchus lapathi (Linnaeus) (Coleoptera: Curculionidae)
In this study, we used scanning electron microscopy to record the number, typology, morphology, and distribution of sensilla on the antennae, maxillary and labial palps in the third, fourth, and fifth larval instars of C. lapathi. Two types of sensilla were observed on the antennae: sensilla basiconica (S.b.1) and sensilla twig basiconica (S.tb.1−4). The maxillary palps had three types of sensilla, S.b.2, S.tb. (S.tb.4−6), and sensilla digiformia (S.d.), while two types were found on the labial palps, S.b.2 and S.tb. (S.tb.4−6). The numbers and types of antennal, maxillary and labial palp sensilla remained unchanged ...
