“…A total of 323 specimens were dissected. Data from Gaza compta Simone and Cunha, 2006, Lithopoma tectum (Lightfoot, 1786), Calliostoma tupinamba Dornellas, 2012, C. adspersum (Philippi, 1851), Solariella obscura (Couthouy, 1838), Carolesia blakei and Omphalius nigerrimus (Gmelin, 1791) were compiled from the literature (Monteiro and Coelho, 2002; Simone and Cunha, 2006; Simone, 2011; Dornellas, 2012; Dornellas and Simone, 2013, 2015; Güller and Zelaya, 2014; respectively), complemented by novel photographic material. The last two species listed were crucial in improving ingroup taxonomic coverage as there was no material available for dissection; they were analyzed in a separate analysis.…”

Morphological phylogeny of the Tegulinae (Mollusca: Vetigastropoda) reinforces a Turbinidae position

2019

A cladistic analysis of the Tegulinae (Turbinidae) is presented using 132 morphological characters and 41 taxa. Tegulinae is recovered and is sister to Prisogaster niger (Prisogasterinae) within the family Turbinidae. This scenario, with Tegulinae as a subfamily within Turbinidae, corroborates with the most molecular analyses. Tegulinae comprises >40 extant species, belonging to eight genera. Morphological studies have not resolved the placement of Tegulinae within Trochoidea sufficiently, and the systematic positions of the genera have never been investigated as a primary objective. The present morphology‐based analysis of genus‐level relationships within Tegulinae provides a robust, phylogenetic diagnosis of each group, rooted on a firm hypothesis of evolutionary relationships. An additional search was performed to include the tegulines Omphalius nigerrimus and Carolesia blakei terminals using unweighted and implied weighting. Our morphological data provide a solid foundation for ensuing systematic research on Tegulinae, as well as Trochoidea, and evidence facilitating the diagnosis of generic and suprageneric groups.

“…Nowadays, detailed studies on squid anatomy are scarce, even though morphological data have proved to be very useful in producing phylogenetic hypotheses and defining relationships within mollusk groups (e.g., Simone, 2011;Couto et al, 2015;Dornellas & Simone, 2015). There are more recent papers about molecular analyses than morphological studies.…”

Morphological comparison between Doryteuthis pleii and D. sanpaulensis (Cephalopoda, Myopsida, Loliginidae) from Brazil

2020

The distinction of squid species in the genus Doryteuthis is not easy due to their morphological similarity, lack of conspicuous specific characters, and overlap geographical occurrence. This difficulty has leading to an almost exclusive molecular approach, and a premature neglect of the morpho-anatomy. To emphasize that the squid phenotypic features can be useful to identify, as well as to perform any comparative analyses (such as taxonomy and phylogeny), two close species were selected as outset. Doryteuthis pleii and D. sanpaulensis are common sympatric squids in Brazilian waters, commonly used in fisheries, not so difficult to distinguish by external features of the adult specimens. The samples were analyzed from biometric data to dissections, and the found most expressive characters to distinguish them are the mantle-fin ratio; morphology of the tentacle club, its ratio compared to the mantle length; hectocotylus morphology and nidamental gland morphology.

“…Alguns dos caracteres radulares foram incorporados ou modificados de Hickman & McLean (1990) que classificaram as subfamílias dos trocoideos baseado em características radulares. Já os caracteres de partes moles foram criados juntamente com estudos morfo descritivos de demais trocoideos (Fretter & Graham, 1962;Righi, 1965;Simone & Cunha, 2006;Dornellas, 2012;Dornellas & Simone, 2013;Dornellas & Simone, 2015). Trabalhos prévios de filogenia morfológica de grandes grupos (p.e., Simone, 2011;Sasaki, 1998;Collin, 2003) foram pouco úteis no levantamento da maioria dos caracteres, uma vez que os caracteres utilizados são aqueles de variação morfológica em grupos hierarquicamente altos (suprafamiliares).…”
