A TAXONOMIC REVISION OF LABIOSTRONGYLUS (LABIOSTRONGYLUS) (YORKE AND MAPLESTONE, 1926) AND LABIOSTRONGYLUS (LABIOMULTIPLEX) N SUBG (NEMATODA, CLOACINIDAE) FROM MACROPODID AND POTOROID MARSUPIALS
Lr. Smales, A TAXONOMIC REVISION OF LABIOSTRONGYLUS (LABIOSTRONGYLUS) (YORKE AND MAPLESTONE, 1926) AND LABIOSTRONGYLUS (LABIOMULTIPLEX) N SUBG (NEMATODA, CLOACINIDAE) FROM MACROPODID AND POTOROID MARSUPIALS, Systematic parasitology, 29(3), 1994, pp. 181-216
The morphological characters used to differentiate species in the genu
s Labiostrongylus Yorke and Maplestone, 1926, parasitic in macropodid
and potoroid marsupials, are discussed. The genus is divided into thre
e subgenera Labiostrongylus (Labiostrongylus), L. (Labiomultiplex) n.
subg. and L. (Labiosimplex) n. subg. on the basis of the presence or a
bsence of interlabia and the morphology of the oesophagus. A key to th
e subgenera is given and a detailed revision of two of the subgenera i
s presented. Keys to each of the subgenera are given, the species disc
ussed being: L. (L.) labiostrongylus (type-species) (syn. L. (L.) insu
laris), L. (L.) grandis, L. (L.) macropodis sp. inq. and L. (L.) nabar
lekensis n. sp., in the subgenus Labiostrongylus, and L. (Lm.) eugenii
, L. (Lm.) novaeguineae, L. (Lm.) onychogale, L. (Lm.) uncinatus, L. (
Lm.) billardierii n. sp., L. (Lm.) constrictis n. sp., L. (Lm.) kimber
leyensis n. sp., L. (Lm.) thylogale n. sp., and L. (Lm.) potoroi, n. s
p., in the subgenus Labiomultiplex.
