Lanceola loveni subsp. grossipes Shoemaker 1945

Description

Lanceola loveni grossipes Shoemaker

(Fig. 1C, D)

Lanceola loveni grossipes Shoemaker, 1945: 209, fig. 16 g, h. Vinogradov 1957: 191; 1960a: 206. Vinogradov et al. 1982: 63–64, fig. 12.

Type material. Shoemaker (1945) described this variety from eight specimens collected near Bermuda, at depths between 600 and 1000 fathoms. He states that “the length of the type female is 29 mm ”. The USNM has three female specimens, the type (109450) and two paratypes (109451 & 2). The whereabouts of the other five specimens is unknown.

Material examined. Types. Holotype female (USNM 109450) and two paratype females (USNM 109451 & 2) from the North Atlantic, near Bermuda [32º12’N 52º36’W]; William Beebe Oceanographic Expedition, col. 7 Sept. 1931, 22 Jun. 1929 & 30 Jun. 1930 respectively: in spirit.

Other material examined. Female 25 mm, semi-mature (SAMA C6252), N. E. Pacific, off Alexander Archipelago, British Columbia [53º59’N 138º46.12’W]; ex M. Galbraith, 250– 150m, 26 Sept. 2001.

Diagnosis. Like typical form except for the following. Length of sexually mature females 27–30 mm. Pereopod 6 is relatively longer with propodus expanded distally into rounded club-shape, housing retractile dactylus. Pereopod 7 is slightly shorter than half-length P6.

Remarks. Described as a mere variety of L. loveni by Shoemaker (1945) it was elevated to sub-specific rank by Vinogradov et al. (1982) and according to them the features characteristic of L. loveni grossipes are only exhibited by sexually mature females.

Distribution. This subspecies has been recorded from the North Atlantic, near Bermuda [32º12’N 52º36’W] by Shoemaker (1945); the North–west Pacific, S.E. of Japan [30º52’N 153º16’E & 30º53’N 153º09’E] by Vinogradov (1957 & 1960a) and N.E. of Marshall Is [16º08’N 173º10’E] by Vinogradov (1960a). The SAMA specimen (Fig. 1) is the first record from the North-east Pacific.
