Abstract:
Ficus watkinsiana (sub-genus Urostigma , Section Stilpnophyllum ) is endemic to Australia, growing in two disjunct populations, one in north-eastern Queensland and the other in south-eastern Queensland and north-eastern New South Wales. Schistonchus molochi sp. n. is described from F. watkinsiana in Queensland, Australia, and differentiated from other species of Schistonchus by a combination of morphological characters including having the excretory pore opening near the nerve ring, a broad head, a large, strongly sclerotised, stylet, a distinct lip sector disc with raised edges, a long post-uterine sac, rose-thorn-shaped spicule, no gubernaculum, three pairs of subventral papillae on the tail (one pair pre-cloacal on the anterior lip, one pair adcloacal on the posterior lip, and one slightly posterior to mid-tail) and bluntly rounded tail tip, and apparent biogeographical range. Presence of the lip sector disc suggests that it is closest to S. macrophylla . Schistonchus athertonensis sp. n. is also described from F. watkinsiana in Queensland and is characterised by a combination of morphological characters, including having the excretory pore opening near the nerve ring, a medium length post-uterine sac, presence of vulval flap in some specimens, rose-thorn-shaped spicule, no gubernaculum, and three pairs of subventral papillae on the tail (one pair adcloacal on the posterior lip, one at three to four-fifths of the tail length and one near the tip), a narrowly rounded tail tip, and apparent biogeographical range. Morphospecies 8, originally collected from F. obliqua , was also collected from F. watkinsiana in Queensland, and S. altermacrophylla was found with it in South Australia. These collections are further evidence of host-switching within Schistonchus .
