The new species Bucephalus damriyasai n. sp. is described from Caranx heberi (Bennett) from off Bali, Indonesia. It can be distinguished from other Bucephalus spp. recorded from carangid hosts by its narrow elongate body shape and the relatively long distance between the rhynchus and the vitellarium, as well as other features distinguishing it from individual species. The most similar species are differentiated from B. damriyasai n. sp. as follows: B. carangis Yamaguti, 1970 has a much greater length, the rhynchus is smaller and the cirrus-sac is small, not always reaching to the posterior testis; B. fragilis Velasquez, 1959 is a tiny species, the pre-vitelline distance is short and the caecum is saccular; B. gorgon (Linton, 1905) is much longer and relatively broader, the uterus reaches distinctly anterior to the vitellarium and the rhyncheal tentacles appear more complex; B. labracis Paggi & Orecchia, 1965 is distinctly longer, slightly broader, with a slightly larger rhynchus, and has shorter pre-uterine and pre-mouth distances; B. paraheterotentaculatus Velasquez, 1959 is much longer, relatively rather broad, the rhynchus is said to bear 21 tentacles, the post-testicular region and cirrus-sac reach are longer and the caecum is described as saccular; B. sphyraenae Yamaguti, 1952 is longer, slightly broader, the uterus reaches anteriorly to the vitellarium and the caecum is claviform and oriented anteriorly; B. margaritae Ozaki & Ishibashi, 1934 (syn. B. varicus Manter, 1940) is relatively squat, has shorter pre-vitelline and pre-mouth distances and a longer post-testicular distance and cirrus-sac reach; B. yamagutii Gupta & Singh, 1985 is broader, with a relatively short pre-vitelline distance, the caecum extends anteriorly to the pharynx, but not posteriorly and the rhynchus is said to carry five tentacles. The distinctive features of B. damriyasai n. sp. are compared with those of all other marine Bucephalus spp. in a table. The number of bucephalid trematodes known from Indonesian waters is now 13, two of them await further identification. They have been described from the fish families Carangidae, Platycephalidae, Sciaenidae, Serranidae and Sphyraenidae.
新物种达姆里亚赛布氏吸虫（Bucephalus damriyasai n. sp.）是从印度尼西亚巴厘岛附近的赫氏鲹（Caranx heberi，贝内特）中描述的。它可以通过其狭窄细长的体型、吻部与卵黄腺之间相对较长的距离以及其他将其与个别物种区分开来的特征，与从鲹科宿主记录的其他布氏吸虫物种区分开来。最相似的物种与达姆里亚赛布氏吸虫的区别如下：1970年的卡氏布氏吸虫（B. carangis Yamaguti）体长更长，吻部较小，贮精囊较小，并不总是延伸到后睾丸；1959年的脆弱布氏吸虫（B. fragilis Velasquez）是一种微小的物种，卵黄前距离短，盲肠呈囊状；1905年的戈耳工布氏吸虫（B. gorgon，林顿）更长且相对更宽，子宫明显延伸到卵黄腺前方，吻触手显得更复杂；1965年的布氏布氏吸虫（B. labracis Paggi & Orecchia）明显更长，稍宽，吻部稍大，子宫前和口前距离较短；1959年的拟异触手布氏吸虫（B. paraheterotentaculatus Velasquez）长得多，相对较宽，据说吻部有21条触手，睾丸后区域和贮精囊延伸更长，盲肠被描述为囊状；1952年的尖吻鲈布氏吸虫（B. sphyraenae Yamaguti）更长，稍宽，子宫延伸到卵黄腺前方，盲肠呈棒状且向前定向；1934年的玛格丽塔布氏吸虫（B. margaritae Ozaki & Ishibashi，同物异名1940年的多变布氏吸虫B. varicus Manter）相对矮胖，卵黄前和口前距离较短，睾丸后距离和贮精囊延伸较长；1985年古普塔和辛格描述的山氏布氏吸虫（B. yamagutii Gupta & Singh）更宽，卵黄前距离相对较短，盲肠向前延伸到咽部，但不向后延伸，据说吻部有五条触手。达姆里亚赛布氏吸虫的独特特征在一个表格中与所有其他海洋布氏吸虫物种的特征进行了比较。已知来自印度尼西亚水域的布氏吸虫吸虫数量现在为13种，其中两种有待进一步鉴定。它们已从鲹科、鲬科、石首鱼科、 Serranidae科和尖吻鲈科鱼类中被描述。
