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 remaine...

Askola Peters 1969 (Ephemeroptera: Leptophlebiidae: Atalophlebiinae): an updated review under cladistics approach
Publication date: Available online 8 September 2019Source: Zoologischer AnzeigerAuthor(s): Rogério Campos, Rodolfo Mariano, Adolfo R. CalorAbstractAskola Peters is a two-winged South American genus of Atalophlebiinae (Leptophlebiidae) and currently comprises five known species primarily described based on male imagos characters, while data from female and immature stages are scarce and often unknown. Herein, Askola was revised under cladistic approach for the first time in order to test the monophyly and to propose the species relationships of the genus. A matrix of 18 species and 34 morphological data was analysed ...

Comparative morphology of immature stages of Ludioctenus cyprius (Baudi di Selve, 1871) (Coleoptera: Elateridae: Agrypninae), with discussion on the monophyly of Hemirhipini
We describe and illustrate for the first time morphology of the mature larva and pupa of Ludioctenus cyprius (Baudi di Selve), and provide information on its biology. Additionally, we compare these immature stages with other genera in Ludioctenina, Hemirhipini and Agrypninae and provide the diagnostic characters for L. cyprius. Within Ludioctenina and related genera, larva of this species is distinguished mainly by the distribution of asperite-like setae and a higher number of tubercles on abdominal tergum IX. The pupa has long and strongly sclerotized prolongations on prothorax, bifurcate and sclerotized urogomphi and a d...

First report of the family Zelinkaderidae (Kinorhyncha: Cyclorhagida) for the Caribbean Sea, with the description of a new species of Triodontoderes Sørensen and Rho, 2009 and an identification key for the family
Publication date: Available online 6 June 2019Source: Zoologischer AnzeigerAuthor(s): Cepeda Diego, Sánchez Nuria, Pardos FernandoAbstractA new species of Kinorhyncha, Triodontoderes lagahoo sp. nov., is described from Tobago Island, Caribbean Sea (western Atlantic Ocean) from a coastal, sandy habitat using both light and scanning electron microscopy. The species is characterized by the presence of middorsal acicular spines on segments 1–11 (that on segment 10 crenulated in males), laterodorsal crenulated spines on segment 10 only in males, lateroventral acicular spines on segments 3–4 and 6–8 (lat...

Comparative morphology of the digestive tract of two Neotropical tree frogs (Genus Boana)
Publication date: Available online 29 May 2019Source: Zoologischer AnzeigerAuthor(s): Bruno S.L. Valverde, Lara Zácari Fanali, Lilian Franco-Belussi, Classius de OliveiraAbstractThe vertebrate digestive system, responsible for providing nutrients for maintaining body homeostasis, consists of two components in anurans: the digestive tract and the accessory glands. The digestive tract includes the oral cavity, pharynx, esophagus, stomach, and small and large intestine, ending in the cloaca. Morphological characteristics of the digestive tract are distinct between anuran species. In this work, we describe the digestive...

Altitudinal variation of community metrics in Italian small mammal assemblages as revealed by Barn Owl (Tyto alba) pellets
Publication date: Available online 30 May 2019Source: Zoologischer AnzeigerAuthor(s): Giuliano Milana, Corrado Battisti, Luca Luiselli, Giovanni AmoriAbstractA databank on the pellets of a widespread owl species (the Barn Owl, Tyto alba) was used in order to evaluate the differences in taxonomical composition and community metrics of small mammals (Rodentia and Soricomorpha) along an altitude gradient in Italy. The databank consisted of data from 292 sites, with altitudes ranging between -6 and 1292 m a.s.l. GLM models showed that the number of Rodentia species decreased significantly with elevation gradient, but increased...

The oviparous olm: analysis & refutation of claims for viviparity in the Cave salamander Proteus anguinus (Amphibia: Proteidae)
Publication date: Available online 28 May 2019Source: Zoologischer AnzeigerAuthor(s): Daniel G. BlackburnAbstractAccounts in the zoological literature commonly state that the European cave-dwelling “olm,” Proteus anguinus, can reproduce “facultatively” -- switching between oviparity and viviparity according to environmental circumstances. This paper evaluates the widespread allegations of viviparity in this salamander species, tracing their origins to ambiguous reports from more than a century ago. The sole basis for detailed claims for “facultative viviparity” lies with an unreliable (a...

The influence of habitat on olfactory organ structure in selected species of salamanders (Salamandridae, Caudata)
Publication date: Available online 28 May 2019Source: Zoologischer AnzeigerAuthor(s): Józef J. Różański, Krystyna D. ŻuwałaAbstractMorphological observations (LM, TEM, SEM) of olfactory organs were conducted on three representatives of the family Salamandridae which differ in post-metamorphic habitat: the terrestrial fire salamander Salamandra salamandra, the semiaquatic alpine newt Ichthyosaura alpestris and the semiaquatic Himalayan newt Tylototriton verrucosus which exhibit increasing specialization towards life in water. We demonstrated variability in proportional size and shape of the main olfactory ...

Partitioning of morphospace in larval and adult reed frogs (Anura: Hyperoliidae: Hyperolius) of the Central African Albertine Rift
Publication date: Available online 8 May 2019Source: Zoologischer AnzeigerAuthor(s): J.Maximilian Dehling, Ulrich SinschAbstractReed frogs of the genus Hyperolius inhabit a wide range of habitats from open savannah to montane forests in Sub-Saharan Africa with frequently sympatric population exploiting the same localities at tadpole and adult stage. Niche partitioning with respect to morphological traits related to diet and locomotion is expected to shape local Hyperolius communities. In a case study on Albertine Rift Hyperolius in Rwanda and Burundi, we analysed the partitioning of larval and adult morphospace (three-dime...

Microanatomy of the female reproductive system of the viviparous freshwater whipray Fluvitrygon signifer (Elasmobranchii: Myliobatiformes: Dasyatidae). I. The ovary
Publication date: Available online 30 April 2019Source: Zoologischer AnzeigerAuthor(s): Nittaya Somsap, Nopparat Srakaew, Kannika ChatchavalvanichAbstractThe microanatomy of the Fluvitrygon signifer ovary was investigated. The females had a single left ovary containing various stages of germ cells and follicles. Both immature and mature female ovaries contained oogonia initially observable in the germinal epithelium as solitary cells or oogonial nests. Herein, three developmental pathways for the oogonia to become primary oocytes are proposed. (1) The single oogonia developed into individual primary oocytes and, in associa...
