BOYKO, CHRISTOPHER B., 2002, A Worldwide Revision Of The Recent And Fossil Sand Crabs Of The Albuneidae Stimpson And Blepharipodidae, New Family (Crustacea: Decapoda: Anomura: Hippoidea), Bulletin of the American Museum of Natural History 2002 (272), pp. 1-396 : 56-57

LEPIDOPINAE , new subfamily

TYPE GENUS: Lepidopa Stimpson, 1858 , designated herein.

INCLUDED GENERA: Lepidopa Stimpson, 1858 ; Austrolepidopa Efford and Haig, 1968 ; Leucolepidopa Efford, 1969 ; Paraleucolepidopa Calado, 1996 .

DIAGNOSIS: Carapace front broad, unarmed or weakly toothed; outer­ocular spines present (except in Lepidopa haigae ); hepatic anterolateral spine present; branchiostegite unarmed. Rostrum present. Distal peduncular segment flattened; cornea absent. Antennule segment I unarmed; dorsal flagellum with 46–250 articles, ventral flagellum with 0–4 articles. Antenna acicle present, short; flagellum with three to nine articles. Maxilliped III carpal projection long; crista dentata absent. Pereopod I dactylus dorsal margin smooth; propodus cutting edge smooth; distodorsal carpal spine absent. Pereopod III male pore present (except in Lepidopa cali­ fornica). Abdomen with pleura on somites II–V. Telson sexual dimorphism weak.

REMARKS: Although Lepidopidae Stammer (1936) ( Crustacea: Mysidacea) is a senior family­level homonym of this new taxon, that name was placed on the ‘‘Official index of rejected and invalid family­group names in zoology’’ as name no. 398 (a family name based on a junior homonym of a genus) ( ICZN, 1964).

The genera that comprise this new subfamily have always been considered to form a natural grouping within the Albuneidae (Efford and Haig, 1968; Efford, 1969), but that group was never formally named. The only genus that was questionably referred to this group was Zygopa ( Holthuis, 1961) , but as shown herein, that genus is allied to Albunea rather than to Lepidopa .
