Comparison of the external morphology of Rhipicephalus sanguineus (Latreille, 1806) (Acari : Ixodidae) ticks from Brazil and Argentina
(Elsevier B.V., 2005-04-20)
In the present study the external morphology of semi-engorged Rhipicephalus sanguineus females ticks from Brazil and Argentina were compared by scanning electron microscopy. Many differences were detected among the R. ...

Larvae of proceratophrys melanopogon (amphibia: anura), with emphasis on internal oral morphology and comparisons with p. cururu and p. moratoi
(Herpetologists League, 2013-06-01)
We provide novel data on the biology of Proceratophrys melanopogon and describe its larval external morphology and internal oral features on the basis of specimens from the Serra do Mar, southeastern Brazil. We also review ...
A comparison of tadpoles of two populations of Leptodactylus plaumanni (Anura: Leptodactylidae), with a discussion of Leptodactylus tadpole morphology
(2018-07-17)
Of the currently known 75 species within the four recognized species groups of Leptodactylus, the L. fuscus group contains 30 species, of which tadpoles are known for 24, including L. plaumanni described based on a population ...
Farfantepenaeus subtilis (Pérez-Farfante, 1967) and F. brasiliensis (Latreille, 1817) (Decapoda, Penaeidae): Ontogenetic comparison using the combined analysis of secondary sexual characters and molecular markers
(2019-08-01)
Most identification keys of species of Farfantepenaeus use the shape of secondary sexual characters as a dichotomic character, but this approach focus only on adults. The lack of similar diagnostic tools for juveniles, ...
Ontogeny as a way to understand morphology of nasal capsule structures in Pipidae, with focus on Pipa arrabali (Lissamphibia: Anura)
(Oxford Univ Press, 2021-10-12)
After more than one-hundred years of studies, there is still no consensus regarding the names for the nasal elements in Pipidae and their correspondence to that of other frogs. Names vary depending on authors' preferences ...
Morphological description and comparison of sperm from eighteen species of cricetid rodents
(Alliance Communications Group Division Allen Press, 2018-12)
Analyses of the dimensions and morphology of spermatozoa can be useful in the identification of mammalian species. We compared and contrasted sperm morphology and dimensions in 9 genera and 18 species of the family Cricetidae. ...
Going underwater: Multiple origins and functional morphology of piercing-sucking feeding and tracheal system adaptations in water scavenger beetle larvae (Coleoptera: Hydrophiloidea)
(Oxford University Press, 2021-09)
Larvae of water scavenger beetles (Coleoptera: Hydrophiloidea) are adapted to a wide variety of aquatic habitats, butlittle is known about functional and evolutionary aspects of these adaptations. We review the functional ...
