LXXXVII.—A preliminary note on two Strongylata from Swine in the Pacific

Abstract

Incisors a little larger than in lateralis, the whole row 10 mm. in length, about as in hachetti, as compared with about 9 mm. in lateralis. Secator also slightly larger than in lateralis, much smaller than in hachetti.

Globocephalus urosubulatus (Alessandrini, 1909) (Nematoda: Ancylostomatidae) in Brazil: a morphological revisitation

“…Worldwide, there are few species proposed for Globocephalus and its well-defined biogeographic distributions: G. longemucronatus Molin, 1861 (Germany and Japan), G. connorfilii Lane 1922 (India, Samoa, China and Taiwan), G. samoensis (Lane, 1922) (Samoa, New Guinea, India, China and Japan), G. sichuanensis Wu 1984 (China), G. amucronatus (Smit & Notosoediro, 1926) (Netherland), G. versteri Ortlepp, 1964, G. madagascariensis Chanaid 1966 (Madagascar), G. urosubulatus (Alessandrini, 1909) (Austria, turkey, New Zealand, French, Germany, Bulgaria, Zaire, Iran, Guyana, Africa, New Guinea, India and America) (Ahn et al, 2015) and G. marsupialis Freitas & Lent, 1936 (America), the last two being recorded in Brazil (Vicente et al, 1997). G. marsupialis the latter being described as a parasite of the small intestine of Philander opossum (Linnaeus, 1758) (Syn.…”

“…There are few taxonomic studies for the genus Globocephalus. Even the original descriptive articles have limitations in their morphological and morphometric data, which makes it necessary to update these data again (Lane, 1922;Cameron, 1924;Freitas & Lent, 1936), as in studies by Nanev et al (2007) for G. urosubulatus collected from wild boars in Bulgaria and Ahn et al (2015) to provide morphological features, and measurements of various parts of the adult nematodes by both light and scanning electron microscopies from G. samoensis in wild boars from South Korea. This is the first study to describe ultrastructural aspects of G. urosubulatus in Brazil, in the world most studies for this species were based on ligth microscopy, but in this study the use of SEM made it possible to observe the mouth opening, distribution of cephalic papillae, deirids, vulva and a panorama of the male's tail, in addition to the presence of a pair of papillae present in the female's tail.…”

On the Nematode genus Globocephalus Molin, 1861

“…GLOBOCEPHALUS SAMOENSIS (Lane, 1922). Synonyms :-Crassisoma samoense Lane, 1922. Raillietostrongylus samoensis (Lane, 1922), Lane, 1923 The material for the study of this form consisted of specimens from Dr. Heydon, New Guinea, some of Dr. O'Connor's material and Lane's types.…”

“…Globocephalus connorfilii Lane, 1922. The material of this species available consisted of specimens from British Guiana, West Africa and New Guinea, in addition to the type material of Lane's Globocephalus connorfilii from Samoa now in the London School of Tropical Medicine.…”
