Material examined

Holotype

WASHINGTON STATE • 1 ♂; San Juan Island , North Bay , Argyle Lagoon ; 48°31′ N, 123°01′ W; 1 m b.s.l.; 9 Aug. 1975; E. Kozloff leg.; muddy sand gravel, rich in organic matter; USNM-53337 . Specimen mounted for LM.

Paratypes

WASHINGTON STATE • 4 ♀♀, 1 ♂; same collection data as for holotype; USNM-53339 . Specimen mounted for LM GoogleMaps .

The description by Higgins (1977a) does not state clearly from which habitat the type material was collected, but sampling was done by E. Kozloff who probably collected the species from muddy sand gravel, rich in organic matter ( Kozloff 1972).

Additional material

CANADA – British Columbia • 2 ♀♀, 1 ♂; Vancouver Island, Clover Point ; 48°24′14″ N, 123°21′04″ W; 0 m b.s.l.; May 2015; M. Herranz leg.; intertidal brown algae (see Herranz & Leander 2016); NHMD- 100304 to 100305 and NHMD-616637 GoogleMaps 1 ♀; Archaeology Beach ; 51°39′52″ N, 128°05′50″ W; 0 m b.s.l.; July 2015; M. Herranz leg.; intertidal brown algae (see Herranz & Leander 2016); NHMD-100306 GoogleMaps .

All specimens mounted for LM. Numerous additional specimens from the same localities, mounted for LM and SEM, are stored in Herranz’ personal reference collection. See Table 1 View Table 1 for an overview.

Description

The species was recently redescribed by Herranz & Leander (2016), and the specimens follow this rather accurate description. The only details that should be added regard the intracuticular substructures related to the female papillae on segments 6 to 8, and middorsal spine length. Female papillae are present in ventrolateral positions on segments 6 and 7 ( Fig. 8E View Fig ), and they have a short, somewhat rhomboid intracuticular tube leading to the rounded outlet. Female papillae on segment 8 are ventromedial ( Fig. 8E View Fig ), and the intracuticular substructures are crescentic with a small protuberance in the curved part of the structure. Middorsal spine of segment 8 extends well onto segment 9, but never reaches posterior margin of segment ( Fig. 8B View Fig ). It was furthermore confirmed that laterodorsal glandular cell outlets type 2 are present on segment 8 only ( Fig. 8B View Fig ).
