Material examined
COLOMBIA: Santa Marta, Punta de Betín, 11.2503° N, 74.2207° W, 20 m deep, SCUBA, coll. M. Kielman, field number SM 132, 1991 ( ZMA Por. 21962).
Description
Small fragment, approximately 2 × 2 × 1 mm in size. Color in alcohol dark brown. Consistency soft.
SKELETON. Confused, a largely unispicular reticulation of oxeas. Few microscleres.
OXEAS ( Fig. 17 View Fig A–A1). Straight, relatively thin, sharply pointed, 232– 289 –315 × 8– 10. 2 –13 μm.
FLAGELLOSIGMAS ( Fig. 17 View Fig B–C). Only six were found; these are circular to ovoid in outline, with long endings with short straight apices, with short endings widely curved. Length of long endings ( Fig. 17B View Fig 1 View Fig ) 70– 82 –95 μm, of short endings ( Fig. 17B View Fig 2 View Fig ) 50– 58 –63 μm, width 55– 61 –75 μm, thickness 2– 2. 4 –3 μm.
NORMAL SIGMAS ( Fig. 17D View Fig ). Robust, symmetrical, strongly incurved apices, 39– 46. 1 –53 × 1.5– 2. 6 – 3.5 μm.
Distribution and ecology
Colombian Caribbean, reef environment at a depth of 20 m (Marine Ecoregion Southern Caribbean). Possibly Cuba (Marine Ecoregion Greater Antilles), 5–9 m depth (see Remarks below).
Remarks
Although the shapes of the flagellosigmas and the sigmas clearly differ from those of the above described H. (F.) hajdui subgen. et sp. nov., this material is not named here because it is too small to allow proper study. Only a few flagellosigmas were found, leaving open the possibility that larger spicules with upturned apices and a more elliptical outline might have been missed. Future study is necessary to delimit the characters of this species against those of H. (F.) hajdui subgen. et sp. nov.
Alcolado (2002) cited Haliclona sp. 2 based on a description of Kaminskaya (1971) of a specimen named Sigmadocia flagellifera from Northwestern Cuba, soft bottom at 5–9 m depth. Oxeas were 115– 220 × 3–5 μm, well below the above measurements, sigmas were cited as 16–64 μm, not differentiated

into flagellosigmas and normal sigmas. These data are insufficient to determine if this record were conspecific with the Colombian specimen.
