Material examined

CHILE • 1 ♀ with red eggs; Canal Ultima Esperanza SE ; -44.5909°, -74.34921667°; 25 m depth; 10 Apr. 2014; HF21; from the leather-coral Alcyonium ; ZMB 34204 ( Fig. 23 ) • 4 specs; Isla Huemules NE , -45.915550°, -73.661367°; 18.3 m depth; 30 Nov. 2011; C 285; in sponge; no depository data.

Distribution

Southern Chile ( Esquete & Aldea 2015) and material from this study.

Depth range

5–18.3 m.

Type locality

Southern Chile, Bernardo O’Higgins National Park: 51°04′04.7″ S, 74°08′29.5″ W, 5–15 m ( Esquete & Aldea 2015).

Type specimen location

Museo Nacional de Historia Natural de Chile (AMP-15038–15039).

Remarks

The specimens studied herein, collected at 18–25 m depth, lived somewhat deeper than the type material (5–15 m), but are collected in an adjacent region. Originally they were found between -49° to -51° and -74° to -75° now they also occur from -44° to -45° and -73° to -74°, thus from less southern and less western Chilean coasts.

Morphologically our material matches perfectly the detailed original drawings of L. kawesqari . Only some additional notes about the urosome are given here: in Esquete & Aldea (2015: 91, fig. 4) the labels of uropod 2 and uropod 3 were mixed up; uropod 2 has the shorter ramus allometric, as in mature animals it is 60% of the longer one and this longer ramus is longer than the peduncle, in younger specimens the difference of the rami is less clear. The shape of the telson is identical to the original drawings, but the distal end in our material has always 3 teeth and 2 setae sitting next to the tip.
