Breinlia tinjili sp. n. (Filarioidea: Onchocercidae) is described from
the thoracic and abdominal cavities of 4 rats, Rattus tiomanicus Mill
er, 1900, from Tinjil, an uninhabited island off the west coast of Jav
a, Indonesia. Breinlia tinjili adult worms have 12 to 13 asymmetrical
perianal papillae, a wide cup-shaped capitulum of both spicules, a 2.5
:1 spicule ratio, a thick trilobed gubernaculum, and numerous cuticula
r bosses scattered along the dorsal and ventral surface of the worm. M
icrofilaria are unsheathed, measure between 273 and 300 mu m in length
, and have 6-9 tail nuclei in a single row and a long lashlike tail. D
escriptions are most similar to B. spratti and B. booliati, but differ
in the following characteristics: the adults are smaller, the guberna
culum is trilobed, paired spicules are smaller, males have an extra pa
ir of postanal papillae, and the microfilariae are much larger in B. t
injili than in B. booliati. Breinlia spratti has a reduced number and
different arrangement of male perianal papillae, a smaller nongrooved
gubernaculum, and smaller spicules compared to B. tinjili. This new sp
ecies appears to share a number of close characters with other Breinli
a species previously described from rodents. The diagnostic value of t
hese characters is discussed.
