We describe two new species of Cypricercus, Cypricercus alfredo sp. nov. and Cypricercus tiao sp. nov., and briefly redescribe the female of Cypricercus centrurus (Klie, 1940) from Brazilian floodplains. Both new species have the elongated carapace which is characteristic of the genus. Cypricercus alfredo sp. nov. was found as both sexual and asexual populations and has a posterior spine on the right valve and differs from the Brazilian C. centrurus by the position and the size of spine and the size and shape of the carapace. Cypricercus tiao sp. nov. was found as one asexual population only and lacks a posterior spine on the right valve. Cypricercus populations in Brazil mostly consist exclusively of asexual females, but some sexual populations and populations with mixed reproduction can also be found. This genus occurs primarily in the Southern Hemisphere, but some species can also be found in the southern part of North America and in India. We also present a re-appraisal of all species presently allocated to the genus, primarily based on original descriptions.

Abstract Two new species of Labidocera from Indonesian waters are herein described. Labidocera baliensis n. sp. is distinguishable in the female by the posterior corners of Pdg5 being rounded and equipped with a sub-posterior spine, the left side of Ur1 with a stout spine-like process, and the form of the P5; in the male by the Ur1 smooth and the very slender shape of P5. Labidocera gagensis n. sp. is distinguishable in the female by having 7 spine-like processes on Ur1, the structure of 6 spine-like processes on the posterior end of Ur2 and the form of P5; in the male by the long spine at the right posterior part of Ur1; and the 5 spine-like processes on the right posterior corner of Pdg5 as well as the form of P5. The relationships between the “detruncata” and “kroyeri” groups are discussed and defining characterizations of the species and of the species groups are provided.

AbstractEight species of Epidamaeus of arctic western North America and extreme northeast, U.S.S.R. are discussed. Two new species, Epidamaeus hammerae and E. tritylos, are proposed and E. arcticolus, E. kodiakensis, E. mackenziensis, E. bakeri, E. coxalis and E. fortispinosus, previously described by Hammer, are redescribed.

Two new species of Bimastos Moore are described based on morphological and molecular data. Bimastos nanae n. sp. resembles B. lawrenceae Fender, B. zeteki (Smith and Gittins) and B. welchi (Smith). Bimastos nanae n. sp. differs from these species in the position of the clitellum, size and number and position of thickened septa. Bimastos magnum n. sp. is similar to B. schwerti Csuzdi & Chang and B. palustris Moore in having a fully annular clitellum and male pores on huge porophores. Bimastos magnum n. sp. differs from both species by having a more posterior position of the clitellum (in xxiv-xxxiii, xxxiv) and larger body size. With the description of these new species, the number of Bimastos species is raised to 14.

AbstractMonelliopsis Richards is composed of small, pale aphids that occur mainly on the Juglandaceae and only in North America. The five known species are: caryae (Monell), nigropunctata (Granovsky), pleurialis Richards, bisetosa new species, and tuberculata new species. The new species were discovered in Chihuahua, Mexico. Monelliopsis nigropunctata is redescribed because the cotypes are a mixture of two species. A key to the known species is given.

The milliped genus Amplaria Chamberlin 1941 was synonymized with Striaria Bollman 1888 by Hoffman (1980). Examination of a much wider range of materials of nominal Striaria species both from eastern North America and the Pacific coastal states shows that some species occurring from California to Washington (state) represent a distinct phyletic line, for which Amplaria Chamberlin 1941 is the oldest available generic name. Speostriaria Causey 1960 is a synonym of Amplaria. Amplaria muiri n. sp. and A. adamsi n. sp. are two new, recently discovered species from caves in Sequoia and Kings Canyon National Parks, California. Illustrations are provided of a specimen that may represent the type species, Amplaria eutypa (Chamberlin) 1953.
