Prochristianella cairae n. sp. is described from the spiral intestines of two species of bamboo sharks, Chiloscyllium
punctatum Müller & Henle and Chiloscyllium indicum (Gmelin) (Hemiscyllidae) off the coast of Malaysian Borneo. The
species is distinguished from congeners by enlarged microtriches covering the whole scolex peduncle, a unique
arrangement of hooks on the basal swelling, a dissimilar number of hooks in each principle row in the metabasal armature
and hook files 1 and 1’ not being distinctly separated. Prochristianella jensenae n. sp. is described from the spiral
intestines of three species of whiptail stingrays, Pastinachus solocirostris Last & Manjaji-Matsumoto, Pastinachus atrus
(Macleay) and Pastinachus gracilicaudus Last & Manjaji-Matsumoto (Dasyatidae) from coastal waters off Indonesian
and Malaysian Borneo and Western Australia, from Himantura uarnak (Gmelin) (Dasyatidae) off Nickol Bay, Western
Australia and from Rhinoptera neglecta Ogilby (Myliobatidae) off Weipa, Queensland, Australia. This species lacks
gland-cells within the tentacular bulbs, one of the most distinctive features of this family. Prochristianella kostadinovae
n. sp. is described from the spiral intestines of Himantura uarnak 2 (Dasyatidae) (sensu Naylor et al. 2012) from the Gulf
of Carpenteria. It differs from congeners in its metrical data, a metabasal tentacular armature with 10 hooks per principle
row, hooks 1(1’) being uncinate with an elongate base and widely spaced and hooks 4(4’) smaller than neighbouring hooks
3(3’) and 5(5’). Prochristianella scholzi n. sp. is described from specimens of the Taeniura lymma species complex
(Dasyatidae) (sensu Naylor et al. 2012) from three localities in Malaysian and Indonesian Borneo. This species has arrays
of billhooks on the basal swelling, but differs from similar congeners in having very few, tiny gland-cells within the
tentacular bulbs and a metabasal tentacular armature with 9–10 hooks per half spiral row and hooks 4(4’) being much
smaller than the neighbouring hooks 3(3’) and 5(5’). Examinations of new material from northern Australia and
Indonesian and Malaysian Borneo provided additional information on Prochristianella aciculata Beveridge & Justine,
2010, Prochristianella butlerae Beveridge, 1990 and Prochristianella clarkeae Beveridge, 1990. In total, 17, 7 and 29
(respectively) new host records and 14, 9 and 28 (respectively) new locality records are added. These records extend the
geographical range of all three species in the Australasian region and also represents the first record of P. aciculata from
Australian waters and the first record of P. butlerae from the Indo-Malayan region. Prochristianella clarkeae is the least
host specific taxon within Prochristianella, infecting 43 different host species.
