Spermiotaxonomy of the tribe Rhodniini (Hemiptera, Triatominae)
(Funpec-editora, 2016-01-01)
The tribe Rhodniini is a monophyletic group composed of 22 species, with 19 in the Rhodnius genus and three in the Psammolestes genus. These insects are morphologically very similar (cryptic species), and new tools are ...
Comparative analysis of germ cells and DNA of the genus Amblyomma: adding new data on Amblyomma maculatum and Amblyomma ovale species (Acari: Ixodidae)
(2017-11-01)
Among tick species, members of the subfamily Amblyomminae have received special attention, since they serve as vectors for pathogens such as Rickettsia spp. and display cryptic species complexes that make their taxonomical ...
Reproductive apparatus of the male giant hermit crab Petrochirus diogenes (Anomura, Diogenidae): morphology and phylogenetic implications
(INTER-RESEARCHOLDENDORF LUHE, 2012)
We describe the male reproductive apparatus of the giant hermit crab Petrochirus diogenes, with morphological and biometric analyses of the spermatophore, the gonopore and the ultrastructure of the spermatozoa. Specimens ...
Reproductive system of the male hermit crab Clibanarius sclopetarius: gonopore, spermatophore, and spermatozoal morphologies
(INTER-RESEARCH, 2011)
In the present study, the morphology and biometry of the spermatophores of the western Atlantic hermit crab Clibanarius sclopetarius (Herbst, 1796) are described, and the results are placed in the context of the Paguroidea, ...
Spermatozoon' structure of the ghost crab Ocypode quadrata (Fabricius, 1787) (Crustacea, ocypodidae) and comments on other Ocypodid spermatozoa
(2011-01-01)
The mature spermatozoon of the ghost crab Ocypode quadrata (Fabricius, 1787) wasdescribed and illustrated at ultrastructural level as a part of a wider program of studies onocypodid crab reproduction carried out in Brazilian ...
Male reproductive system of the red brocade hermit crab Dardanus insignis (Diogenidae) and its relationship to other family members
(Springer, 2014-06-01)
The reproductive system of hermit crabs shows species-specific morphology, which can be used in phylogenetic analysis. Here, we describe the male reproductive system of the hermit crab Dardanus insignis, including morphological ...
Ultrastructure of spermatophores and spermatozoa of intertidal crabs Pachygrapsus transversus, Pachygrapsus gracilis and Geograpsus lividus (Decapoda: Grapsidae)
(2017-07-01)
Pachygrapsus transversus, P. gracilis, and Geograpsus lividus are intertidal crabs, whose ultrastructure of spermatophores and spermatozoa are unknown. In this work, we characterized the ultrastructure of the spermatophores ...
Comparative analysis of spermatids of Rhipicephalus sanguineus sensu lato (Ixodidae) and Ornithodoros rostratus ticks (Argasidae): morphophysiology aimed at systematics
(Springer, 2015-10-19)
The phylogenetic relationships among tick species (Acari: Ixodida) have been revisited by several researchers over the last decades. Two subfamilies, Rhipicephalinae (Ixodidae) and Ornithodorinae (Argasidae), deserve special ...
