Eulimnadia graniticola n. sp. from Stone Mountain, Georgia, and the Florida Keys, USA, is defined primarily on molecular characters and egg morphology. Ecological, reproductive and life history data are provided. This species is the second species of branchiopod crustacean reported from Stone Mountain more closely related to the South American fauna than to its North American congeners.

A new species of Sphaerephesia is described from Mamala Bay, south shore of Oahu, Hawaii. Sphaerephesia mamalaensis sp. nov., differs from its congeners by the absence of microtubercles and number and arrangement of body and parapodial papillae. This species is commonly found in low abundance in shallow (20 m) and deep-waters (500 m) adjacent to ocean outfall diffusers or dredge dump sites and has been resilient to the waste water treatment plume of the outfalls for the last 25 years. A comparative table with morphological characteristics of all seven recognized species of Sphaerephesia is provided. Copyright © 2011 - Magnolia Press.

A new species, Monokalliapseudes guianae, is described from French Guianese estuaries. It is distinguishable from its only congener most notably by lacking an exopodite on pereopod 1 and by the nature of the basal article of the uropod. The inner distal corner of the basal article is only slightly produced and lacks a rounded lobe. The bases of pereopods 2 and 3 lack numerous long setae. Sexual dimorphism is observed in the antennule, cheliped, and pereopod 1. Depending on size, males can exhibit two forms of chelae. A new diagnosis is presented for the genus Monokalliapseudes. © 2015 Proceedings of The Biological Society of Washington.

Multiple specimens of the rusty crayfish (Orconectes rusticus) collected from the Susquehanna River in Pennsylvania exhibited Rheotanytarsus sp. (Diptera: Chironomidae) living on their carapaces and chelipeds. Although chironomid larvae have been reported as living on many aquatic organisms, this is the first record of chironomids living phoretically on crayfish. © 2012, American Midland Naturalist.

We present a checklist of the large branchiopod crustaceans of Idaho, Oregon and Washington, USA. New distributional records are presented for most species, including the first records of Branchinecta constricta Rogers, 2006 and Lepidurus cryptus Rogers, 2001 from Idaho, the first record of B. oriena Belk and Rogers 2002 from Oregon, the first record of B. mackini Dexter, 1956 and Artemia franciscana Kellogg, 1906 co-occurring, and the first record of L. cryptus from Washington. Furthermore, we present the first record of Eulimnadia diversa Mattox, 1937 from west of the continental divide, which we interpret as an accidental introduction. In 1959, Lynch collected a new fairy shrimp species from Washington, deposited that material in the US National Museum, labeled "muddy fairy shrimp, Branchinecta lutulenta", but never described it. Numerous efforts have been made to rediscover extant populations since 1999. We rediscovered this species in 2011, from two small pools from the vicinity of Lynch's original collection site, which appears to have been destroyed. Branchinecta lutulenta sp. nov. is most closely related to B. lindahli Packard, 1883 and B. oterosanvicentei Obregón-Barboza et al., 2002. Branchinecta lutulenta sp. nov. is readily separable from all other Branchinecta species by the form of the male second antennal distal antennomere and the ornamentation of the female dorsum.
