Bezzia ventanensis Spinelli, a new Neotropical species, is described and illustrated based on pupae and adults. Pupae werecollected from muddy water from the edge of a stream margin in Sierra de la Ventana, Buenos Aires province, Argentina.Specimens were carried back to the laboratory and conditioned in vials until adult emergence. This new species is similarto Bezzia brevicornis (Kieffer), from which it can be mainly distinguished by the female adult bearing two well developed spermathecae, and by the pupal respiratory organ with 13–15 spiracles.

AbstractPetasiger argentinensis sp. nov. is described from material found in the intestine of the Great Grebe, Podiceps major (Boddaert) and the White-tufted Grebe, Rollandia rolland Quoy et Gaimard (Podicipediformes, Podicipedidae), from Argentina. The new species is characterized by the head collar armed with 19 spines and by the testes arranged in tandem. These characters are shared with only two Neotropical species of the genus, P. novemdecim Lutz, 1928 and P. combesi Zamparo, Overstreet et Brooks, 2005. Petasiger novemdecim differs from the new species in having a larger body, longer collar spines, larger eggs, a cirrus-sac of similar size to the ventral sucker and almost entirely anterior to it, and vitelline fields confluent ventrally posterior to the ventral sucker. P. combesi differs from the new species in most metrical characters, the shape of the body (antero-posteriorly elongate) and the location of the genital pore (dextral) and the excretory pore (dorsal). This is the first record of a member of the genus Petasiger parasitizing birds from Argentina.

The male, pupa and fourth instar larva of Ablabesmyia platensis sp. n. from La Plata, Buenos Aires province, Argentina and the pupa of A. bianulata Paggi collected in southern Argentina are described and figured. The male adult diagnosis of A. bianulata is emended, and the aedeagal complex is redescribed and photographed. Differences in the aedeagal complex and the color pattern of the pupa mainly distinguish these two species. The new species is also compared with the Neotropical A. oliveirai Oliveira et Gessner.

AbstractDolichorchis lacombeensis sp. nov., a digenean parasite of the gut of the cocoi heron, Ardea cocoi (L.), is described as a new species from Buenos Aires Province, Argentina. This new species most closely resembles D. buteii and D. tregenna in the distribution of the vitelline follicles, which reach the intestinal bifurcation in the forebody. D. buteii can be distinguished from D. lacombeensis sp. nov. by the distribution of the vitelline follicles in the hindbody, which are concentrated in midline, by the presence of a sphincter in genital pore and by the size of holdfast organ and posterior testis, which are larger, (240–400 × 176–240 and 315–464 × 240–410 µm, respectively). D. tregenna differ from the new species by their larger measurements (pseudosuckers’ length 90–100, pharynx 52–90 × 50–70 and eggs 89–104 × 48–68 µm).

Thirty-nine species of Sarcophaginae are recorded from Buenos Aires Province (Argentina). A new species, Microcerella asymmetrica sp. nov., is described. Females of Oxysarcodexia bicolor Lopes, O. marina Hall, and Sarcophaga (Lipoptilocnema) koehleri Blanchard are described for the first time. Four nomenclatorial actions are reported: Sarcohelicobia elegans Blanchard is established as a new junior synonym of Nephochaetopteryx cyaneiventris Lopes, and lectotypes are designated for Oxysarcodexia delpontei Blanchard [a junior synonym of Oxysarcodexia paulistanensis (Mattos)], Sarcophaga argentina Brèthes [a junior synonym of Sarcophaga (Liopygia) argyrostoma (Robineau-Desvoidy)], and Neobellieria brethesi Blanchard [a junior synonym of Sarcophaga (Neobellieria) polistensis Hall]. Blaesoxipha (Tephromyia) hospes (Aldrich), Peckia (Euboettcheria) florencioi (Prado & Fonseca), Ravinia advena (Walker), R. aureopyga (Hall) and Sarcodexia lambens (Wiedemann) are newly recorded from Buenos Aires Province, and Udamopyga percita is newly recorded from Argentina. A key is presented to the adult males and females of 36 of the 39 species of Sarcophaginae recorded from Buenos Aires province. Notes on distribution, biology, life history and host records are also given.

Hippomonavella charrua n. sp. is introduced based on material from the continental shelf off Uruguay. Bilaminar fragments of this species were also found in mid-Holocene deposits of Destacamento Río Salado Member, Canal de las Escobas Formation (Buenos Aires Province, Argentina), ca. 6,000 yr BP. Hippomonavella charrua n. sp. resembles H. brasiliensis Ramalho, Muricy & Taylor, 2008, but differs from this species in its more triangular and protruding avicularia occurring in just a small proportion of zooids. Hippomonavella charrua n. sp. is the third species of the genus with both fossil and Recent representatives. The tatiform ancestrula and the early astogeny are described for the first time in a species of Hippomonavella.

A New Species

A new species of Peltephilidae (Mammalia, Xenarthra, Cingulata) (early Eocene–late Miocene) is described here. Thenew taxon is based on three specimens collected from the margins of Arroyo Chasicó, Buenos Aires Province, (Argenti-na), which correspond to the Arroyo Chasicó Formation (late Miocene, Chasicoan SALMA). The new species is charac-terized by osteoderms with a very rough exposed surface showing high longitudinal and well developed crests (two lateraland one central) with deep and ample valleys among them. The new taxon is the only “relictual” xenarthran cingulate ofthe Santacrucian Age (late early Miocene) to be registered for the last time in the Chasicoan SALMA (late Miocene), and represents the youngest record of the family Peltephilidae.
