Figure 12

Lubbockia squillimana Claus, 1863:164, 165, pl. 25: figs. 1–5.—Giesbrecht, 1892:606–611, pl. 4: fig. 6, pl. 48: figs. 1, 2, 4–8 17–19, 21.

Lubbockia minuta.—Marukawa, 1927:1237, fig. 2384. [Not L. minuta Wolfenden, 1905.]

Lubbockia marukawai Mori, 1937:122, 123, pl. 67: figs. 10–13.

Specimens that we studied from different areas varied as little as did ones from within the same sample, and all specimens agreed with Giesbrecht's (1892) excellent description. We have supplemented this description of L. squillimana, because of the additional Lubbockia species that have been added since Giesbrecht's study.

MATERIAL STUDIED (Tables 1, 2).—MEDITERRANEAN SEA, Gulf of Naples: 20 females, 1.29–1.67 mm, M 47, USNM 168505; 3 males, 1.98–2.09 mm, M 47, USNM 168505. Western Mediterranean: 3 females, 1.33–1.48 mm, M 46. ATLANTIC OCEAN, near Florida: 82 females, 1.22–1.44 mm, TA 45; 3 males, 1.75–1.86 mm, TA 45, USNM 168506. Off Bahamas: 1 damaged male, TA 44.

FEMALE.—Body and all appendages with unusually thick exoskeleton, with complex sclerotized pattern in some areas (Figure 12a,b).

Antenna 1 as in L. wilsonae.

Labrum (Figure 12c) with free margin divided into 2 posteroventral lobes, each margin with a row of processes on under surface; short medial hood over apex.

Maxilla 2 (Figure 12d) with armature similar in number to that of L. carinata.

Legs 1–4 armature similar to that of L. aculeata; legs 2 and 3 (Figure 12e,f) and leg 4 endopods terminate with a vent between spines.

DISTRIBUTION.—Lubbockia squillimana, like L. aculeata, has a definite tropical distribution, although a few specimens have been collected just outside tropical waters. Principal records and summaries are from the Pacific Ocean (Giesbrecht, 1891; Farran, 1936; Mori, 1937, 1942; Wilson, 1950); Indian Ocean and Indo-Pacific (Scott, 1909; Krishnaswamy, 1953); Atlantic Ocean (Giesbrecht, 1892; Marques, 1958; Owre and Foyo, 1967; Vives, 1972); and the Mediterranean Sea (Razouls, 1974).
