Halacarid mites (Acari: Halacaridae) from Esperance, Western Australia: Notes on taxonomy and faunal distribution of non-Copidognathinae

Abstract

-A recent survey on the halacarid fauna of Esperance (Western Australia) resulted in records of more than 40 species. The genera, and in parentheses the number of species, are: Actacarus

First record of Atelopsalis pacifica (Acari: Halacaridae) from Turkey

“…However, A. atlantica bears an areola on OC which is not on A. pacifica, and has costae on PD almost twice broader than that found on A. pacifica. The species were identified following the description of (Bartsch, 1985), Sarma &(Chatterjee, 1990 and(Bartsch, 2007). The general morphology of our specimens agree with the studies.…”

“…The species of Atelopsalis pacifica was first time found at 15 m depth, in the shallow subtidal zone of Philippines (Mactan Island) by Bartsch (1985). After that, the species recorded from India (Bay of Bengal) by Sarma & (Chatterjee, 1990) and Western Australia (Rottnest Island and Esperance) by Bartsch (2007). The present study constitutes the fourth record of this species from the world seas and stand as the first report of the genus from the Turkish coastal waters.…”

“…The characters of that single female are: length of idiosoma 340 µm, width 239 µm, anterior margin of AD with lamellar, almost rectangular projection, 22 µm wide; AD with pair of porose costae and anteriorly with median ovate porose areola; OC with two porose areolae, one immediately medial to two corneae, one halfway between corneae and medial corner of plate; porose longitudinal costae of PD separated from transverse posterior costa; AE with pair of garland-like areolae and a median areola, circular in outline and adjacent to posterior margin of plate; GA with two pairs of porose areolae, anterior one crescentic, posterior pair ovate; rostrum slightly shorter than gnathosomal base; ventral margin of telofemur I with two apically dentate spines and short rounded lamella. The species is most similar to Agauopsis calidictyota Bartsch, 2007, A. decorata Otto, 1999and A. inflata Newell, 1984, the first mentioned species is known from the southern coast of Western Australia, the second from Queensland, eastern Australia and the third from Chile (Newell 1984;Otto 1999;Bartsch 2007). The AD of Agauopsis inflata bears a similar almost rectangular lamellar projection, but in contrast to the specimen from Singapore, the costae on the PD extend to the posterior transverse porose areola, there is no median porose areola adjacent to the posterior margin of the AE, and the rostrum is longer than the gnathosomal base.…”

“…Characters (according to Otto 1994and Bartsch 2005b, 2007a. Length of females 278-437 µm, of males 382-424 µm.…”
