TYPE HOST: Thylogale billardierii (Desmarest, 1822). TYPE LOCALITY: Launceston, Tasmania. SITE OF INFECTION: Stomach. SPECIMENS STUDIED: Types from T. billardierii, from Tasmania; 10 male, 14 female from Launceston, collectors D. Obendorf, I.

tion in a circular buccal capsule. The nerve ring is in the mid-esophageal position in P. tasmaniensis but is posterior and surrounds the isthmus in P. pearsoni. Popovastrongylus wallabiae, the other species occuring in Tasmania (Mawson, 1977), has a quadrangular mouth opening and a buccal capsule circular in cross-section. The submedian papillae of P. wallabiae are short, and the setae are not easily seen at low magnifications, while P. tasmaniensis has prominent papillae and setae. The dorsal lobe of the bursa of P. tasmaniensis is shorter (about the same length as the lateral lobes), not longer than the lateral lobes as in P. wallabiae. Additional characters that distinguish P. tasmaniensis from P. irma are not having the base of the buccal capsule thickened by an outer sclerotized ring and having the nerve ring in a mid-esophageal, not posterior, position surrounding the isthmus. The shape of the posterior end of the female of P. irma, constricted between vulva and anus and markedly swollen in the vaginal region, is unique to P. irma. Popovastrongylus thylogale, also occurring in pademelons, can be further distinguished from P. tasmaniensis by an annular thickening around the middle of the buccal capsule, the posterior position of the nerve ring, and the dorsal lobe longer than the lateral lobes of the bursa. Popovastrongylus tasmaniensis differs further from P. macropodis in having a relatively thinner inflation of the lining of the buccal capsule, which is expanded anteriorly but does not almost occlude the lumen as in P. macropodis. Popovastrongylus pluteus sp. n. (Figs. 22-31) Description GENERAL DESCRIPTION: Small worms; body covered with numerous fine transverse striations; mouth opening circular, surrounded by elevated, finely striated collar indented on external margin; cephalic collar present, posterior to lateral collar bearing 2 amphids and 4 cephalic papillae each with 2 setae. Buccal capsule cylindrical, circular in cross-section, longer than wide; walls sclerotized, refractile, thickened in posterior part; inner lining thick, transparent, folded in mid-region to produce irregular shelf-like projection, almost occluding lumen. Esophageal corpus long, isthmus not distinct, bulb ovoid. MALES (measurements of 2 specimens): SMALES—POPOVASTRONGYLUS FROM MARSUPIALS 55 Length 5, 6 mm; width 240, 290; buccal capsule 33, 46 long by 26, 26 wide; esophagus 0.985, 1.01 mm long; nerve ring to anterior end 402, 402; deirids to anterior end 135, excretory pore to anterior end 470, 455. Spicules 950. Dorsal and lateral lobes of bursa about equal in length, ventral lobes shorter. Ventral rays apposed, reaching margin of bursa; externolateral ray divergent, almost reaching margin of bursa; mediolateral and posterolateral rays apposed, reaching margin of bursa; externodorsal ray arising close to lateral trunk, almost reaching margin of bursa; dorsal ray dividing at midlength into 2 arcuate branches that reach margin of bursa, lateral branchlets short, arising close to bifurcation; terminating in small elevations on internal surface of bursa. Anterior lip of genital cone large and conical, with single apical papilla; posterior lip smaller, with 2 bilobed appendages. Spicules elongate, alate, tips not seen. Gubernaculum absent. FEMALES (measurements of 10 specimens): Length 7-8 (7.4) mm; width 255-375 (305); buccal capsule 35-50 (40) long by 22-30 (26) wide; esophagus 1.02-1.14 (1.08) mm long; nerve ring 345-390 (370), deirids 105-140 (125), excretory pore 400-475 (435) from anterior end; tail 470-585 (530) long, vulva to posterior end 705-885 (790); vagina 400-595 (505); eggs 95-105 (100) by 42-52 (45). Tail long, slender with conical tip; vulva immediately anterior to anus; vagina short, broad at anterior end, ovejector with vestibule and sphincters about same length, infundibula shorter; eggs ellipsoidal. Taxonomic Summary TYPE SPECIMENS: Holotype male SAM A AHC 31253, allotype female AHC 31324, paratypes 3 female, 1 male AHC 14546. TYPE HOST: Macropus robustus Gould, 1841. TYPE LOCALITY: Rivertree, New South Wales. SITE OF INFECTION: Stomach. SPECIMENS STUDIED: Types from M. robustus, New South Wales; 17 female from Rivertree, 28 August 1975, SAMA AHC 31252. ETYMOLOGY: The specific name refers to the shelf-like projection in the buccal capsule. Remarks Popovastrongylus pluteus sp. n. is 1 of 2 species with a shelf-like projection in the buccal capsule, the other being P. pearsoni.
