First report of Paelopatides (Synallactida, Synallactidae) for the SW Atlantic, with description of a new species from the deep-sea off Argentina
Publication date: Available online 5 November 2018Source: Zoologischer AnzeigerAuthor(s): Mariano I. Martinez, Francisco A. Solís-Marín, Pablo E. PenchaszadehAbstractThe present study describes a new species, Paelopatides shumel n. sp., from Argentinian deep-sea waters. This is the first report of the order Synallactida for Argentina, the fifth for southern hemisphere and the deepest report for the Argentinian holothuroid fauna (almost 3000 meters). The species has up to 330 mm length, light brown color and around 19 pairs of dorsal appendages. The ventral side has one ventral ambulacra, with two rows of tube feet. Ossic...

Comparative morphology of selected foretibial traits of Asopinae (Hemiptera: Heteroptera: Pentatomidae)
Publication date: Available online 2 November 2018Source: Zoologischer AnzeigerAuthor(s): Ricardo Brugnera, Kim Ribeiro Barão, Talita Roell, Augusto FerrariAbstractLegs structures are very diverse among Heteroptera groups and usually, these are related to life habits. In the family Pentatomidae, the foretibia is usually cylindrical and little variable among taxa, but the predatory stink bugs of the subfamily Asopinae shows pronounced structures. Using light and scanning electron microscopy the foretibial expansion and the foretibial apparatus of 87 and 42 species (respectively) of Asopinae were studied, representing about...

Wing Vein Shape Signal In Culicoides oxystoma (Schultzei Group) In Nigeria - Tool For Discrimination (Diptera: Ceratopogonidae) Using Geometric Approach
This study utilized landmark-based geometric morphometric approach in differentiating wing venation patterns of C. oxystoma, C. enderleini, C. schultzei and C. subschultzei, thus providing baseline data for classification of biting midges in Nigeria. The wing shape of C. oxystoma revealed specific variability with at least two morphologic variants that were hitherto unclassified. Landmarks on the first dorsal and cubital veins contributed 68% and 92% of all variations and distinguished C. oxystoma from others in the group; both shape and size elements were found responsible for species discriminations. Only one morpho-typi...

Associating larvae and adults of the Neotropical caddisfly genus Synoestropsis Ulmer (Trichoptera: Hydropsychidae) using morphology and DNA mitochondrial sequences
Publication date: Available online 23 October 2018Source: Zoologischer AnzeigerAuthor(s): Patrik Barcelos-Silva, Ana Maria Pes, Vanderly Andrade-Souza, Ralph W. HolzenthalAbstractSynoestropsis is the only Neotropical representative of the Macronematinae tribe Polymorphanisini. Adults of Polymorphanisini are recognized by the absence of maxillary and labial palpi. Currently, Synoestropsis contains 10 described species recorded from northeast Argentina to southern Mexico. Until now, the larval stages of only one species were described, Synoestropsis furcata Flint. The goals of the present work are to associate larvae and adu...
