Micropagurus devaneyi McLaughlin, 1986: 794 , figs. 3a–i, 4a–e.— Haig & Ball, 1988: 184 — Gunn & McLaughlin, 1988: 67.

Material examined. Holotype, ♀, SL = 1.1 mm, from its base of a Pocillopore meandrina, stn. 6B of Hawaiian Electric Company Survey, Kahe Point, Oahu, Hawaii, 22°22'N, 158°08'W, 5 Aug. 1977, coll. S. L. Coles, BPBM . Paratypes: 1♀, SL = 1.1 mm, stn. 7c, Kahe Point, Oahu, Hawaii, 14 Oct. 1977, BPBM ; 1♀, SL = 1.2 mm, stn. 5B#, Kahe Point, Oahu, Hawaii, BPBM ; 2♂, SL = 1.2, 1.3 mm, Kahe Point, Oahu, Hawaii, BPBM . Other material: 1♀, SL = 1.1 mm, 2 ov. ♀ SL = 1.2, 1.2 mm, all specimens with brown ocular peduncles, 18 m, algae wash, "Marty's reef" off Hahuna Point, Maui, Hawaii, coll. Cory Pittman, 27 Apr. 2002, USNM 1073324 ; 1♀, SL = 1.4 mm, specimen with red ocular peduncle, same locality, collector and date, USNM 1073325 .

Diagnosis. Shield longer than broad; ocular peduncles 0.7–0.8 length of shield; corneas dilated; pair of interocular lobes prominent; ocular acicles each with 3–6 spines on distal margin; antennular peduncles reaching nearly to bases of corneas; antennal peduncles not reaching to bases of corneas, third segment with minute spinule at ventrodistal margin or unarmed, second segment with dorsolateral distal angle produced and terminating in simple or bifid spine, dorsomesial distal angle with small spine; antennal acicle with mesial margin bearing small spine in distal half and frequently additional spine basally, lateral margin usually with basal spine.

Third maxilliped with merus and carpus each bearing strong dorsodistal spine.

Right cheliped stout; dactyl with row of small corneous teeth distally and 2 calcareous teeth proximally on cutting edge, dorsomesial margin with row of spines; palm with dorsal surface only weakly convex, with single row of spines proximally becoming double rows distally but not extending onto fixed finger, dorsomesial margin with irregular single or double rows of spines, dorsolateral margin with row of strong acute spines extending onto fixed finger, cutting edge of fixed finger with row of small calcareous teeth; carpus with dorsomesial and dorsolateral margins each with row of strong spines; merus with ventromesial margin bearing strong spine in distal half, ventrolateral margin usually with distal spinule.

Left cheliped slender; cutting edge of dactyl with row of small corneous teeth; palm with dorsal surface bearing 1 or 2 rows of spines in midline but not extending onto fixed finger, dorsomesial margin with short row of acute spines, dorsolateral margin with row of small spines extending onto fixed finger only proximally, cutting edge of fixed finger with row of moderately strong corneous teeth; carpus with dorsomesial and dorsolateral margins each with row of strong spines; merus with ventromesial margin bearing acute spine in proximal half and smaller subdistal spine.

Second and third pereopods similar; ventral margins of dactyls each with 2–4 corneous spines; propodi with ventrodistal margins each bearing corneous spine or spinule; carpi with dorsal surfaces each bearing 2 or 3 spines.

Male with coxa of left fifth pereopod bearing well­developed sexual tube; no gonopore on right coxa.

Telson with terminal margin rounded, unarmed, or with few spinules.

Coloration. In life, ocular peduncles red or brown (field note by Cory Pittman).

Distribution. Known only from the type locality, Oahu, and Maui, Hawaiian Islands.
