Antennule flagella well developed, accessory flagellum at least 0.5 length of main flagellum. Mandible navicular. Maxillule palp with 2 setae. Pereopod 1 slender, basis equal to all other articles together. Pereopod 5 longer than pereopod 4 basis. Telson long, 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 short, modified clasping antenna, without penial lobes, without pleopods.
Species. Lamprops beringi Calman, 1912, L. fasciatus Sars, 1863, L. fuscatus Sars, 1865, L. korroensis Derzhavin, 1926, L. northwindae n. sp., L. pumilio Zimmer, 1937, L. sarsi Derzhavin, 1926.
Type species Lamprops fasciatus Sars, 1863, by monotypy.
Remarks. The original conception of this genus by Sars included species only with a clasping antennal flagellum in the adult male, thus all the species with a long, non–clasping flagellum in the male, and those species with unknown males, have been removed to Alamprops.
