Lamprops.— Sars, 1863: 239 (in part).
Type species. Lamprops augustinensis Gerken, 2005.
Diagnosis. Carapace not dorsoventrally flattened, without marginal carina, eyelobe present, pseudorostral lobes short, blunt. Antennule flagella well developed, accessory flagellum at least 0.5 length of main flagellum. Mandible navicular. Maxillule palp with 2 setae. Pereopod 1 basis subequal to rest of appendage. Pereopod 5 longer than basis of pereopod 4, with 6 articles. Telson large, at least 2/3 length of uropod peduncles. Uropod endopod of 3 articles. Uropod exopod article 1 0.2 length of article 2, or less, rarely longer than article 2. Female with fully developed exopod on pereopod 2, rudimentary exopods on pereopods 3–4, without pleopods. Male with long antenna, extending past pereon, penial lobes absent, without pleopods.

Etymology. A meaning “not”, in combination with lamprops, to indicate that these species have been removed from the genus Lamprops sensu Sars. Gender masculine.
Remarks. All the species initially included by Sars in the genus Lamprops Sars, 1863, had males with a short, clasping antenna (Lamprops sensu Sars). However, other authors added species with males with long antennae to the genus, without addressing the disparity or discussing the dilution of the generic definition. Where known, adult males of the species in the new genus have a long antenna, extending past the pereon, necessitating their removal from Lamprops. As the majority of cumacean species have a long antenna in the male, species previously included in Lamprops sensu lato in which the adult male is unknown are also included in the new genus. It is unfortunate that the females of Alamprops and Lamprops as restricted here are indistinguishable, except by reference to the individual species descriptions. However, to maintain consistency, and in line with Sars’ (1863) original conception of the genus Lamprops, it is necessary to remove the species from the genus that have a long, or non-clasping, antenna in the adult male.
