A recent publication in Biology Letters added a new family, Eleutherodacytlidae, to the list of frogs known to possess defensive, toxic alkaloids in their skin— the so-called ‘poison frogs’ [1]. The alkaloids have attracted much attention since they are not synthesized by frogs de novo, but rather are obtained from dietary sources and subsequently sequestered in the frogs’ skin [2]. These ‘clep...

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 litter green moss in Arsi Mountains National Park. Adults differ praestantissimus (Berlese, 1916) having fusiform, distally pointed bothridial seta, absence prolamella, presence well-developed notogastral setae ...

In this paper the differentiation of external morphology and ontogeny of Oribatulidae were investigated, on the basis of Phauloppia lucorum (C. L. Koch, 1841), Lucoppia burrowsi (Michael, 1890), and Oribatula tibialis (Nicolet, 1855), which ontogeny is described and illustrated here for the first time. The juveniles of these species have smooth cuticle, a clavate sensillus with barbed head, and...
