NEW SYNONYMY. Type material. Type material of Lycaea bovallii is in the Musée Océanographiqe de Monaco, Monaco (MOM). A holotype was not designated but a male from Hirondelle stn. 16 is illustrated by Chevreux (1900). Specimens were collected by the L’Hirondelle from the N.E. Atlantic, near the Azores [38°06’N 29°18’W], stn. 16, surface, 3 August 1885 (MOM 37 0019, 2 females, 3 males, in alcohol) and the N.E. Atlantic [48°19’N 19°30’W], stn. 30, surface, 27 August 1885 (MOM 37 0025, one juvenile, in alcohol) and [42°50’26”N 45°25’W], stn. 148, surface, 28 July 1887 (MOM 37 0025, one juvenile, in alcohol). Type material of synonyms. The type material of Lycaea bajensis is in the USNM: the holotype male (USNM 52361) and 8 paratypes, 1 female, 7 males (USNM 52462). The type locality is the N.E. Pacific, Gulf of California. The holotype male (7 mm) and 8 paratypes are from off San Josef Island (“Isla San José”). Shoemaker also lists additional material from this locality and from off Cape San Lucas (5) and from off Carmen Island (3) but most of these specimens could not be found in the USNM. However, there are two lots amongst the general collection, one male from Carmen Island (USNM 52463) and three poorly preserved specimens from Cape San Lucas (USNM 52464) that should be considered paratype material. Unfortunately, the latter lot has only one specimen, a male that could be referred to L. bajensis; the remaining two specimens are females that are more readily identified with L. pulex and L. vincentii. An examination of this material has confirmed the above synonymy. Several syntypes of Lycaea gracilis are in the Naturhistorisches Museum Wien, in alcohol (NHMW 20163). Several specimens were collected from the Red Sea; Pola stns. 22–25, 64, 82, 108, 118, 136, and a male is illustrated by Spandl (1924). The long dactylus of P4, the relatively long peduncle of U1, the morphology of G1 and G2, and of the male A1 are all characteristic of L. bovallii. Several syntypes of Lycaea bovallioides (4–5 mm) are in the NHMD, all labelled “Type”, in alcohol. Specimens were collected by the Thor from surface waters in the Mediterranean Sea, stn. 163 [37°52’N 26°22’E], 3 August 1910 (1 female, NHMD-83719, previously CRU-5875) and stn. 718 [36°13’N 13°53’E], 17 May 1913 (1 female, NHMD-86792, previously CRU-9293), and from the N.E. Atlantic, near Madeira, stn. 398 [36°48’N 14°22’W], 26 October 1911 (1 female, 1 male, NHMD-86789, previously CRU-9290); stn. 399 [34°23’N 15°31’W], 26 October 1911 (3 females, 3 males, NHMD-86790, previously CRU-9291) and stn. 400 [32°10’N 17°20’W], 30 October 1911 (12 males, NHMD-86791, previously CRU-9292). The figured male is from stn. 400 (Stephensen 1925) and is here designated the lectotype, the remaining syntypes become paralectotypes. An examination of this material has confirmed the above synonymy. Material examined. Type material of Lycaea bajensis and L. bovallioides as detailed above and the following. In NHMD: N.
