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.

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.

Three species of the genus Allocosa Banks, 1900 from southern South America are redescribed: Allocosa alticeps (Mello-Leitão, 1944), A. brasiliensis (Petrunkevitch, 1910) and A. senex (Mello-Leitão, 1945). The female of A. senex is described for the first time and the species is revalidated. A new species, A. marindia sp. nov. from southern Uruguay and southern Brazil is described. The new species is distinguished by the flattened terminal apophysis of the male bulb and the conspicuous pointed projections on the posterior margin of the female epigynum. The species inhabits in sandy estuarine and oceanic coasts with psammophile vegetation.

The genus Procerobaetis Kaltenbach & Gattolliat, 2020 is reported for the first time from Thailand, and Procerobaetis totuspinosussp. nov. is described as a new species based on larvae. It can be easily distinguished from other known Procerobaetis species by the presence of triangular spines at the posterior margin of tergites VI–IX. COI sequences were obtained from all known species. The genetic distances (Kimura 2-parameter) between the new species and the other species are between 20% and 23%. The morphological characters of the new species and its closely related species are discussed; larval key to all species of the genus Procerobaetis is also provided.

AbstractDuring the course of a study on the endohelminth parasites of birds, specimens of an undescribed species of Tylodelphys Diesing, 1850 (Diplostomidae) were collected from the wood stork, Mycteria americana L., from Formosa Province, Argentina. Tylodelphys brevis sp. nov. can be distinguished from the other Neotropical species of this genus, T. elongata, T. americana and T. adulta, principally by the smaller size of the body (570–851 μm), by the fewer eggs in the uterus (1–2) and by the smaller ratio of body to egg length (6–8). This is the second report of an adult of the genus Tylodelphys from Argentina and the first record of a digenean species parasitizing Mycteria americana in this country.

The oribatid mite genus Dorycranosus (Oribatida, Liacaridae) is recorded for the first time from the Neotropical region. One new species, Dorycranosus grenadaensis sp. nov. is described from ferns and mosses near lake in the forest of Grenada (Antilles). The new species differs from Dorycranosus shipitsyni (Ermilov, Rybalov & Kemal, 2011) by the body surface, length of notogastral and adanal setae.

A New Species

A new species of the genus Spinaethorax Papáč & Palacios-Vargas, 2016, recently erected for two cave species of Mexico, is described from a Vietnamese cave. It differs from the Mexican species most noticeably by the dorsal chaetotaxy of the head (number and morphology of chaetae), the shape of S-chaetae on the third antennomere, the dorsal chaetotaxy of the abdomen and the chaetotaxy of the dens. The pattern of special τ-chaetae is described for the first time in the genus. The affinities between Spinaethorax and the other genera of Neelipleona are discussed. Spinaethorax is probably closely related to Neelus Folsom, 1896. A table of the differential characters is provided for the three known species of Spinaethorax. Spinaethorax appears to be restricted to caves, but its presence in Vietnam indicates that this genus has a much larger distribution than previously recognized.
