摘要

根据阿尔西山脉国家公园的枯枝落叶和青苔中采集的成虫和幼龄，描述了一种新的沙氏蝶属（Oribatida，Scheloribatidae）物种——沙氏蝶（Scheloribates）arsizonensis n.sp。新物种的成虫与S.praestantissimus praestantiassimus（Berlese，1916）的不同之处在于，它们具有纺锤形、远尖的双侧刚毛，没有前釉层，并且存在发育良好的脊背刚毛p1。本文对该新种的幼体与其他Scheloribates种的幼体进行了比较。新物种的幼崽与其他已知的S.（Scheloribates）的幼崽的区别在于，在所有龄期的胃孔上都存在两个强壮的、长的、纵向的背外侧褶皱，长的胃刚毛c3，在若虫龄明显长于其他胃刚毛，和在双节中不存在毛刚毛的情况下。

Ontogenetic instars of the oribatid mite Scheloribates arsizonensis n. sp. (Acari, Oribatida, Scheloribatidae) from Ethiopia

A new species of the genus Scheloribates (Oribatida, Scheloribatidae) — S. (Scheloribates) arsizonensis n. sp. — is described from Ethiopia, based on adult and juvenile instars, collected from litter and green moss in Arsi Mountains National Park. Adults of the new species differ from S. praestantissimus praestantissimus (Berlese, 1916) in having fusiform, distally pointed bothridial seta, the absence of prolamella, and the presence of well-developed notogastral setae p1. The comparison of juveniles of the new species with juveniles of other Scheloribates species is presented. Juveniles of the new species can be distinguished from the other known juveniles of S. (Scheloribates) by the presence of two strong, long, longitudinal, dorsolateral folds on the gastronotum in all instars, long gastronotic seta c3, which is distinctly longer than other gastronotic setae in nymphal instars, the presence of vestigial gastronotic seta h3 in larva, and in the absence of aggenital setae in deutonymph.

期刊介绍： Acarologia is a free open-access journal. Please help us by submitting manuscripts in accordance with following instructions. All manuscripts which do not conform to the instructions will be returned to authors without the benefit of review. Acarologia publishes the results of original research on all aspects of Acarology. The journal policy is that taxonomic descriptions should include several species within a same genus/family, when possible. The editors reserve the right to refuse manuscripts when authors intentionally divide individual species descriptions of the same genus/family into distinct publications. Single species descriptions should be clearly justified based on their scientific interest.
