Crepis longipes, the type species, is redescribed and stabilized by typification. The description of Crepis verticillatais amplified. Three new species are described, all of them previously identified as C. longipes: Crepis harmelini n. sp. from the Strait of Gibraltar, Crepis sidneyi n. sp. from the Indo-Pacific region, and Crepis sinensis n. sp. from the South China Sea. A new genus, Mourellina n. gen., is erected for Crepis decussata, which is split into two species: Mourellina decussata n. comb, and Mourellina gonzaloi n. sp. This genus is placed in its own family, Mourellinidae n. fam., of uncertain affinities. Thediagnosis of the family Chlidoniidae, which up to now included the genera Chlidonia and Crepis, is modified by excluding the latter genus.

The original specimens of its type-species—S. illibatus Sellnick, 1918—were lost and the genus has received no further empirical study. For many years Strieremaeus was included in the family Eremaeidae, but recently this placement was questioned. Herein we redescribe S. illibatus based on the study of 31 non-type adult specimens from both Baltic and Rovno ambers. Among these are four Baltic specimens identified by Sellnick and currently deposited in the Kaliningrad Museum of Amber (KMA), which we designate as neotype (KM A 197-36) and paraneotypes (KMA 197-34, 197-35, and 197-37). Six immature specimens were associated with this species, of which three—one deutonymph, two tritonymphs—could be studied in detail and their characters are included in the redescription. The type specimens of a second species of Strieremaeus proposed by Sellnick—S. cordiformatus Sellnick, 1918—are also lost and two non-type specimens in the KMA seem to have been misidentified by Sellnick; therefore, we treat S. cordiformatus as a species in-quirenda. A new diagnosis of Strieremaeus is presented, and the Cretaceous fossil genus Archaeorchestes is considered a junior subjective synonym, based on examination of the holotype of the type-species, A. minguezae Arillo & Subias, 2000. As a consequence, Strieremaeus is currently the sole genus in Archaeorchestidae. Strieremaeus minguezae(n. comb.) is only tentatively maintained as a distinct species, as no certain distinguishing traits could be found. Two families are reported from the fossil record for the first time: Zetomotrichidae from Baltic amber and Zetorchestidae from Rovno amber. In ancillary discussion we note how the specialized tarsal structure of S. illibatus is consistent with its likely arboreal habitat. We also discuss preservation properties and artifacts, note the dimensional discrepancy between cuticular remnants ofthe mite and its larger imprint in amber, and strongly recommend measuring more than the cuticular remnants themselves. Further, we provide information on different methods to observe amber inclusions, and for the first time report birefringence of fossil cuticular remnants in thin, airless preparations.

Two species, Otacilia hengshan (Song, 1990) comb. nov. and O.foveata (Song, 1990) comb, nov., are transferred from the genus Phrurolithus. The male of O.foveata is reported for the first time. A distribution map of those three species is provided.
