Alguns nematodeos do genero Aplectana Railliet & Henry, 1916

A new species of Aplectana (Nematoda, Cosmocercidae) in Platymantis boulengeri (Anura, Ceratobatrachidae) from Papua New Guinea

“…Only 2 other species have been reported with 5 precloacal pairs of papillae, A. membranosa (Schneider, 1866) and A. travassosi (Gomes et Motta, 1967). Aplectana membranosa has 5 precloacal, 2 adcloacal, 4 postcloacal and 1 median papillae (Miranda 1924); A. travassosi has 5 precloacal, 1-2 adcloacal, 4 postcloacal and 1 median papillae (Dyer 1990). …”

Aplectana artigasi n.sp. (Nematoda: Cosmocercidae) from the Frog Eupsophus calcaratus (Anura: Leptodactylidae) in Southern Chile

“…Compared with descriptions of the above mentioned species by Miranda (1924), Travassos (1931), Lent andFreitas (1948), da Silva (1954), Pallarés and Maciel (1974) Baker (1980), Baker and Vaucher (1986) and Dyer (1990), the new species can be distinguished from A. membranosa, A. micropenis, A. vellardi, A. hylambatis, A. lopesi, A. elenae, A. paraelenae, A. pudenda, A. travassosi, and A. macintoshii because it does not have a gubernaculum.…”

On a New Species of Oxysomatium Railliet and Henry, 1913 and Some Notes on the GeneraOxysomatium andAplectana

“…The present species differs from the following species of Oxysomatium and Aplectana in the number and arrangement of the caudal papillae, size of spicules and gubernaculum and the body size:-Oxysomatium americanum and 0. longicaudatum Walton, 1929, 0. baylisi Walton, 1933, 0. georgianum Reiber, Byrd and Parker, 1940, 0. mexicanum Caballero, 1933, 0. ranae Walton, 1931, Aplectana brumpti Travassos, 1931, A. flindersi Johnston and Mawson, 1943, A. incerta Caballero, 1949, A. micropenis Travassos, 1925, A. pusilla Miranda, 1924, A. chameleonis Baylis, 1929, A. hamatospicula Walton, 1940, A. hoffmanni and A. itzocanensis Bravo Hollis, 1943 (Schneider, 1866) Miranda, 1924, A. unguiculata (Rud., 1819) Miranda, 1924, A. vellardiTravassos, 1926and A. raillieti Travassos, 1925. From the last eight species of Aplectana the present species also differs in having a relatively small pharynx.…”

“…They accordingly renamed Schneider's species as Oxysomatium longespiculum and placed Zeder's species in a new genus Aplecta (subsequently found to be pre-occupied and amended to Aplectana, and made Ascaris acuminata Schrank, 1788 as its type. Skrjabin (1916) recognized Zeder's species 0. brevicaudatum as the type of the genus Oxysomatium and included four other species, 0. contortum (v. Linstow, 1906), 0. unguiculatum (v. Linstow, 1906, 0. perezi (Gendre, 1911) and 0. dogieli Skrjabin, 1916. Miranda (1924 regarded Aplectana as the valid genus and included in it his species A. pusilla, together with Ascaris unguiculatus Rudolphi, 1819 and Leptodera membranosa Schneider, 1866.…”
