DESCRIPTION: (CIECR007601): Length 8.12 mm, pereon length 4.58 mm, maximal width 6.2 mm, head length 0.94 mm, head width 1.87 mm, distorted 36 ° (fig. 1A, B). All segments distinct. Head with narrow frontal lamina, anterior edge of head deeply bilobate (fig. 1A), eyes lacking. Antennule of three articles, antenna of five articles, terminally setose. Maxilliped (fig. 1C, D) with setose palp, plectron sharp, anterior article two times larger than posterior article. Barbula with two pairs of smooth falcate lateral projections on each side (fig. 1E).

Pereon broadest across third pereomere (fig. 1A). Coxal plates very reduced, only visible on first three pereomeres of long side. Dorsolateral bosses on first three pereomeres of longer side, and first four pereomeres on shorter side. Tergal projections on longer side extended, tapeing distally to sharp tip. Brood pouch open (fig. 1B). Oostegite 1 (fig. 1F, G) with nearly smooth internal ridge, posterolateral point lacking. Posterior pereopods larger than anterior pairs, ischium with enlarged tubercular lobe, dactyli blunt (fig. 1H, I). Pleon of six pleomeres, first five pleomeres with lateral plates and uniramous pleopods. Sixth pleomere without lateral plates, with uniramous uropods (fig. 1B).

DESCRIPTION: Male (CIECR007601): Len‐ gth 2.26 mm, maximal width across pereomere 4, 0.71 mm, head width 0.43 mm, head length 0.20 mm, pleonal length 0.55 mm. (fig. 1K, L). Head elliptical, separated from first pereomere (fig. 1K). Black eyes near posterior edge of head (fig. 1K). Antennule of three articles, antenna of four articles, terminally setose (fig. 1M). Pereomeres distinct, subequal in width, midventral projections lacking (fig. 1L). Dactyli of first pereopod larger others (fig. 1N). Pleon fused into single ovate piece, pleopods and uropods lacking; anal cone usually lacking (occasionally present) (fig. 1O).

VARIATIONS: The head of some females is so deeply biobed it looks like a pair of spheres united. One female specimen (CIECR530401) with an extremely bulging head, very extended, terminally sharp tergal projections (fig. 1J) and the surface of the lateral plates are crenulated. One male (CIECR510401) with anal cone on the terminal end of the pleon (fig. 1O).

REMARKS: This species has an extremely wide range, occurring in both the northeast and northwest Pacific on at least 23 crangonid hosts. Specimens from Japan, Korea, and China have been well described, but northwestern Pacific specimens are much more poorly known. Richardson (e.g., 1905b) described the species in some detail, but a fuller redescription, especially of characters now known to be informative at the species level, is needed. An example of a possible difference between northwestern and northeastern Pacific specimens, based on literature review, is that the northwestern specimens appear to have moderate to pronounced bilobation of the head, while northeastern specimens have a nearly flat head in dorsal view (see, e.g., Gifford, 1934). Additionally, given the wide geographic range of the species, a molecular analysis of specimens from both sides of the Pacific should be undertaken to test the possibility of cryptic species.

There are three hosts of this species in China and one of these, Crangon cassiope , is the type host for Argeia pingi Yü, 1935 , which was only very briefly described, not illustrated, and never reported subsequent to its original description. Markham (1977) thought A. pingi might be a synonym of A. pugettensis . Because this host has now been recollected and is infested with Argeia specimens that do not differ from A. pugettensis as currently defined, A. pingi is here considered a synonym of A. pugettensis . However, if future moleculer and/or morphological analyses show any differences warranting recognition of the northeastern and northwestern populations as distinct species, A. pingi would likely be the valid name for northwestern Pacific specimens, assuming that all northwestern Pacific specimens are conspecific. However, the type specimens of A. pingi appear to be lost and a neotype would be required.
