Emended Diagnosis

AbstractA new species of Dendrorchis is described and compared with others in the genus. The parasites were found in the swim bladder of the annual killifish Cynopoecilus melanotaenia. Hosts were collected from a seasonal wetland in southern Brazil. The main characteristics of D. pampae are: genital pore in the intestinal bifurcation region elongate and lobed vitellaria uterine loops limited to the acetabular region and to the rear end of the body; and wide intestinal caeca. An emended diagnosis of the genus Dendrorchis includes the characteristics of the new species. This is the first record of an adult digenean in an annual killifish from South America.

Phalacrocorax Brasilianus

A new species of the genus Andracantha Schmidt, 1975, parasite of Neotropical cormorants, Phalacrocorax brasilianus (Gmelin, 1789), is described and compared to the other six species currently placed in the genus. The new species differs from the previously known species of Andracantha by having two inflations in the anterior region of the trunk and by having the testes in tandem in the central region of the body. These differences were also responsible for the diagnosis emendation of the genus now proposed. The orange pigmentation of the acanthocephalans recently collected from the intestine is documented for the first time in a species of this genus. This is the first record of adult specimens of any species of Andracantha in South America.

The tribe Diglottini Eichelbaum, 1909 comprises two halophilous rove beetle genera Diglotta Champion, 1899, and Paradiglotta Ashe & Ahn, 2004. The tribe contains eight known species distributed in the Nearctic and West-Palaearctic regions, and also Fiji Islands and New Zealand. This tribe is recorded for the first time from South America with the description of a new species, Diglotta brasiliensis n. sp. from southern Brazil (Paraná). Characters of the mouthparts, aedeagus and spermatheca of the new species are illustrated and compared with other Diglotta species. Sexual dimorphism is reported for the first time in the genus.

A New Species

ABSTRACT A new species of Ituglanis associated to the grasslands of the Pampa biome is described from the rio Uruguai basin, southern Brazil. The new species is distinguished from its congeners by the low number of ribs and by a unique color pattern composed of an outer layer with scattered round black blotches equivalent in size to the eye circumference over a reddish brown background on the lateral surface of the body. We provide the genetic sequences of the mitochondrial gene Cytochrome c Oxydase subunit I (COI) for three of the paratypes and discuss aspects about the recent discovery of the new species.

A New Species

Cestrus itatiensis sp. nov., from the Brazilian Atlantic Forest, is described and illustrated. This is the southernmost record for the genus and the first record in Brazil. The new species is characterized by having the body reddish brown; a narrow yellow stripe along eye margin on supra-clypeal area, reaching briefly the supra-antennal area; transverse carina of propodeum complete and stout; postpetiole and T2–8 progressively dark brown towards apical margin in a somewhat triangular pattern; and apex of dorsal valve of ovipositor with nine distinct teeth. Extensive sampling suggest this is a rare species.

A New Species

Cruznema brevicaudatum is described as a new species because its lips are not distinctly set off, and it has nine pairs of tubular and one pair of pyriform bursal ribs. Two diverticula of unknown function occur at the junction of the vas deferens and seminal vesicle. This is the first record of a Cruznema as an insect associate. Indiana coimbatoriensis is recognized as a new species on the basis of size and arrangement of spines on the body and lateral field. Only females were found.

Four specimens—one male and three females—mounted in Canada Balsam were sent from Rio Javary, South America. In this condition nothing can said about their colour, and very little about the nature of their hairy covering, except that all parts of the body are apparently hairy, as usual, and that the hairs that are left on the abdomen are very long and almost recumbent.

A new species of Lamellarea (Oribatida, Lamellareidae) is described from hick twigs of southern live oak in Florida, U.S.A. (part of the Neotropical region). Lamellarea americana sp. nov. differs from most similar species, Lamellarea digitata and L. forceps by the ventrally inserted lamellar setae, the number of genital setae, the length of interlamellar setae, and the body size. Remarks on generic diagnosis and distribution of Lamellarea are presented.

Vespertilionid Bats

Pterygodermatites are parasitic nematodes found in mammals worldwide, except Australia. There are 38 described species, which are found parasitizing bats, rodents, marsupials, carnivores and primates. We present taxonomic notes on nematodes collected from the digestive tract of bats from the Atlantic Forest in southeast Brazil. Two species previously recorded in marsupials in this region, Pterygodermatites (Paucipectines) elegans and Pterygodermatites (Paucipectines) jagerskioldi, were found parasitizing molossid and vespertilionid bats, respectively. A new species Pterygodermatites (Pterygodermatites) atlanticaensis found in phyllostomid bats is here described. Despite earlier work based on females, taxonomic work on this group of nematodes is usually based on male characters, such as position and number of caudal papillae, which is a problem because males are short-lived and not easily found. Here we also describe in detail female characters, such as position of the last pair of cuticular processes relative to the posterior end. This is the first record of P. (Pterygodermatites) in South America and the first record of P. (Paucipectines) jagerskioldi in bats.
