Anamixis yarrega (J. L. Barnard 1974)

Leucothoides yarrega

DIAGNOSIS.—Head evenly rounded at anteroventral corner; coxa 1 not covering anteroventral corner of head or eye; both setules of coxa 1 situated at apex; articles 5–6 of gnathopod 1 lacking gioss serrations on apposing margins, some specimens with extraordinarily minute marginal serrations on article 6; spines on article 6 of pereopods 1–2 evenly distributed; article 2 of pereopod 5 of broad form, posterior margin weakly scalloped, setules deeply inserted.

Mouthparts generally like those of L. pottsi as illustrated by Shoemaker (1933); on Figure 63 spine bases of right mandible shown as circles, inner plate of maxilla 1 broad and truncate, maxilla 2 of broad form as in L. pottsi, inner plate of maxilliped flat, spinose apical margin long as in L. pottsi, bearing three spines, outer plate as shown for L. torrida.

HOLOTYPE.—NMV, female, 2.05 mm.

TYPE-LOCALITY.—VicFish 512, Western Port, Victoria, Station 41N–2–1+2, 42 feet, 30 March 1965.

MATERIAL.—Western Port, Victoria, VicFish, 4 samples (4).

DISTRIBUTION.—Western Port, Victoria.

Leucothoides species V from Loggerhead Key

DIAGNOSIS.—Head with weak mammilliform protrusion at anteroventral corner; coxa 1 covering anteroventral corner of head and part of eye; one setule removed to ventral margin of coxa 1, other setule at apex; articles 5–6 of gnathopod 1 serrate on apposing margins; spines on article 6 of pereopods 1–2 unevenly distributed; article 2 of pereopod 5 of broad form, posterior margin weakly serrate, setular insertions deep and very weak.

Mouthparts like those shown by Shoemaker (1933) for L. pottsi.

MATERIAL.—Loggerhead Key, 10 August 1924, collected by W. L. Schmitt (2 females; f2=female, 2.22 mm; f 3=female, 2.32 mm).

Leucothoides species Q from Albatross 2406

DIAGNOSIS.—Head evenly and broadly rounded at anteroventral corner; coxa 1 not covering anteroventral corner of head or part of eye (as far as can be determined); both setules on coxa 1 situated at apex, anteroventral part of coxa 1 weakly attenuate; articles 5–6 of gnathopod 1 serrate on apposing margins; spines on article 5 of pereopods 1–2 evenly distributed; article 2 of pereopod 5 of broad form, posterior margin weakly serrate, setules unclear.

Differs from L. pottsi in uneven distribution of spines on pereopods 1–2.

Specimens are “mushy” and article 2 of pereopod 5 is covered with fibrous crystals, setules therefore poorly observed; position of head and coxa 1 also poorly observed.

MATERIAL.—Albatross 2406, Gulf of Mexico, 28° 46′00″N, 84°49′00″W, 26 fathoms, Blake trawl, coarse sand, 15 March 1885 (3 specimens; figured specimen, ?sex, 2.8 mm, denoted as “g”).

Leucothoides species 2 from Micronesia

This species is characterized by the short process on article 5 of gnathopod 1. Only one specimen is available. The characteristic may be an aberrancy but the specimen should not be destroyed by dissection in search of other characters until other material becomes available.

MATERIAL.—One specimen from Abbott 594, formerly identified as L. pottsi by J. L. Barnard (1965), specimen deposited in Smithsonian Institution. The two other specimens from this sample are apparently juveniles of Leucothoe micronesiae J. L. Barnard and are not L. pottsi as identified by Barnard (1965).
