diagnosis
Diagnosis. Carapace without lateral ridges, antennal notch absent, pseudorostrum pointed, eyelobe small. Telson 1.0 length of uropod peduncles, 0 pairs lateral setae, 5 terminal setae. Uropod peduncle with 1 medial seta. Adult male entire antenna including flagellum only as long as uropod. Depth. 0 – 92 m.
discussion
Remarks. There is only one other species of Lamprops with a single lateral ridge on the carapace, L. beringi; however, L. beringi and L. sarsi can be differentiated by the telson setation. In L. beringi the telson has 3 terminal setae, while in L. sarsi the telson has 5 terminal setae. The most similar species in Alamprops is A. pseudosarsi, which has three ridges on the carapace, although the posterior ridge may be quite weak. The placement of this species in Lamprops is quite clear, as the male is without pleopods and the antenna 2 is quite short. However, uropod exopod article 1 is distinctly longer than article 2, which suggests that the use of uropod exopod article ratios is not an exceptionally useful character to differentiate genera.
