“…For general measurements, the helminths were fixed with AFA, under slight cover slip pressure, following the protocols established by Amato et al (2007) and Seixas et al (2010). The specimens were stained with Delafield's hematoxylin or aceto-carmine/fast green, cleared in cedar oil, and mounted as permanent slides on Canada balsam.…”

SEIXAS, S.A., DAMETTO, N., PÉRICO, E. New species of Temnocephala (Platyhelminthes, Temnocephalida) ectosymbiont on vulnerable species of aeglids (Crustacea, Anomura) from the Neotropical Region. Biota Neotropica. 18(4): e201704725. http://dx.doi.org/10.1590/1676-0611- BN-2017-0475 Abstract: A new species of the genus Temnocephala Blanchard, 1849 from southern Brazil was found on two species of anomuran crustaceans, Aegla spinipalma Bond-Buckup & Buckup, 1994 and Aegla grisella Bond-Buckup & Buckup, 1994, the latter classified as a vulnerable species by the "Lista de Referência da Fauna Ameaçada de Extinção no Rio Grande do Sul. Decreto no 41.672, de 11 junho de 2002". The crustaceans were collected from a tributary creek of the Forqueta river, Perau de Janeiro, Arvorezinha and a tributary creek of the Fão river, Pouso Novo, Rio Grande do Sul, Brazil; both localities belong to the Sub-Basin of Forqueta River. The new species differs from seven other temnocephalans epibionts on Aegla Leach, 1820, by having the following characters: 1. a long and slightly curved cirrus, 2. two vaginal sphincters, one proximal, big and asymmetric, and one distal, smaller and symmetric, and; 3. longer than wide, elongated epidermal 'excretory' syncytial plates (EPs), with a almost horizontally central excretory pore, displaced to the anterior portion of the plate. The new species' EP is the largest in total length among epibionts temnocephalans in crustaceans already registered. Regarding the similarities with the male reproductive system of Temnocephala axenos Monticelli, 1898, the new species has important differences in the female reproductive system. It has a larger proximal vaginal sphincter, located in the middle of the vagina, while the smaller distal one is at the extreme end of the organ. Besides that, the vaginal portion between the proximal and distal sphincters is conspicuous, with a strong muscular wall. This is the first record of a species of Temnocephala in the Taquari Valley, as well in the 'Perau de Janeiro', which is an area with a rich endemic fauna.

“…In this context, Temnocephala species (Platyhelminthes) have been recorded associated with invertebrate and vertebrate hosts, including insects (Amato & Amato 2005;Amato et al 2007;Vianna & de Melo 2002), molluscs (Damborenea 1998;Seixas et al 2010), crustaceans (Damborenea 1998) and turtles (Volonterio 2010). As for temnocephalan-host associations, interactions between chironomids and their host have been recorded involving a great array of animals (Roque et al 2004;Marques et al 2008), mainly insects, such as megalopteran larvae (Callisto et al 2006).…”

“…Some of the helminths taken from live hosts were studied and photomicrographed alive or fixed and stained according to SEIXAS et al (2010a) for internal morphometry. To preserve the red pigmentation of the eyespots and the shape of the body, and for the purpose of scanning electron microscopy studies (SEM), some specimens were flooded in hot phosphate buffered 10% formalin (HF) (AMATO et al , 2006.…”
