Male and female reproductive morphology in the inseminating genus Astroblepus (Ostariophysi: Siluriformes: Astroblepidae)
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
The structure of the reproductive organs of males and females of four species of Astroblepus were studied by light microscopy and TEM. In females, the gonadal and urinary orifices are separated. The urinary pore opens at ...

The evolutionary implications of hemipenial morphology of rattlesnake Crotalus durissus terrificus (Laurent, 1768) (Serpentes: Viperidae: Crotalinae)
(Public Library of ScienceSan Francisco, 2013-06)
Most amniotes vertebrates have an intromittent organ to deliver semen. The reptile Sphenodon and most birds lost the ancestral penis and developed a cloaca-cloaca mating. Known as hemipenises, the copulatory organ of ...

The rise of internal fertilization in the Anablepidae (Teleostei, Cyprinodontiformes): Two new genera and species from the Miocene of Tucumán, Argentina
(Wiley Blackwell Publishing, Inc, 2018-05)
Two new genera and species of Cyprinodontiformes from the Miocene of Tucumán, Argentina, are described: Tucmanableps cionei and Sachajenynsia pacha. Both exhibit sexual dimorphism, indicated by the modification of the male ...
A review of the genus Anisodiscus Gaud & Mouchet (Acari, Proctophyllodidae) from Madagascar sunbirds (Passeriformes: Nectariniidae), with observations on male genital morphology
(2013-09-19)
In the present article, we review the feather mites of the genus Anisodiscus Gaud & Mouchet, 1957 associated with sunbirds of Madagascar (Passeriformes: Nectariniidae). Anisodiscus goodmani sp. nov. is described from ...

Ultrastructure of spermatozoa of orsolobidae (Haplogynae, Araneae) with implications on the evolution of sperm transfer forms in Dysderoidea
(Wiley, 2014-11)
Haplogynae are highly diverse with respect to the primary male genital system and sperm characteristics. Additionally, all sperm transfer forms (STF) known for spiders are present. Besides individually transferred sperm ...
Phylogenomics and genital morphology of cave raptor spiders (Araneae, Trogloraptoridae) reveal an independent origin of a flow-through female genital system
(Wiley Blackwell Publishing, Inc, 2019-11)
The monotypic family Trogloraptoridae was only recently described from caves and old-growth forest of Oregon and California (Western USA). These enigmatic spiders are characterized by striking raptorial claws, and based ...
