Lepidepecreum Bate and Westwood 



Lepidepecreum Bate and Westwood, 1868. — Stebbing, 1906. 



Type-species: Anonyx longicornis Bate and Westwood, 1863 

 (monotypy and subsequent synonymy). See Sars, 1895. 



Article 1 of antenna 1 usually carinate {combining characteristic) 

 but occasionally not; accessory fiagellum absent (type) or present; 

 epistome broadly produced in front of upper lip; body often dorsally 

 carinate or toothed; mandibular molar a setulose, quadrate lamina, 

 palp attached proximal to molar; gnathopod 1 subchelate, articles 5 

 and 6 subequal; telson long, deeply cleft. Some species approach 

 Orchomene complex. Species: 19, bipolar, amphiboreal, littoral to 

 bathyal. 



Lysianassa Milne Edwards, provisional synonymy 



Lysianassa Milne Edwards, 1830. — Stebbing, 1906. 



Lysianassina Costa, 1867. 



Lysianax Stebbing, 1888. 



Lysianopsis Holmes, 1903; 1905. Type-species: L. alba Holmes, 1903 (mono- 

 typy). See Shoemaker, 1933b. 



Aruga Holmes, 1908. Type-species: A. oculata Holmes, 1908 (monotypy). 



Arugella Pirlot, 1936. Type-species: A. heterodonta Pirlot, 1936 (original designa- 

 tion) . 



Shoemakerella Pirlot, 1936. Type-species: Lysianassa nasuta Dana, 1853 

 (original designation). Hurley (1963) notes that Pirlot's diagnosis of Shoe- 

 makerella fits Lysianax cubensis Stebbing, 1897, and not -L. nasuta. However, 

 the latter should remain as type-species because it was so designated. 



fPronannonyx Schellenberg, 1953. Type-species: P. minimus Schellenberg, 1953 

 (monotypy). [See also in alphabetical order.] 



Type-species: L. costae Milne Edwards, 1830 (denoted by elimina- 

 tion of Milne Edwards, 1840, and selected by Boeck, 1876). Species 

 obscure. Genus based here on L. plumosa Boeck (L. costae of Sars, 

 1895, pi. 16, fig. 1). 



Upper lip strongly lobate in front of epistome or epistome pro- 

 duced forward along with upper lip; mandibular molar large, coni- 

 colaminate, unridged or nearly obsolete, palp attached proximal to 

 molar; gnathopod 1 simple, articles 5 and 6 subequal; inner ramus of 

 uropod 2 unconstricted (L. plumosa), or constricted (L. longicornis); 

 outer ramus of uropod 3 uniarticulate; telson entire, emarginate, or 

 minutely notched. Species, including synonymous genera: 24, 

 cosmopolitan, littoral (rarely in bathyal). Species with aberrant 

 maxilla 2: L. hypocrita Ruffo.
