Material examined. RMNH Por. 9770, Guyana, ‘Luymes’ Guyana Shelf Expedition, station 95, 6.9°N 57.5°W, depth 23–24 m, mixed hard bottom, 3 September 1970 GoogleMaps .
Description. A mass of creeping encrusting branches ( Fig. 17 View FIGURE 17 a) consisting of a series of connected lobes, each provided with an oscule. Size of the mass of branches about 6 x 4 cm, thickness of individual branches 3–5 mm, lobes up to 8 mm high, oscules 2–3 mm in diameter. At several places there are creeping tendrils. Surface optically smooth. Color (in alcohol) pale beige. Consistency soft.
Skeleton. The ectosomal reticulation ( Fig. 17 View FIGURE 17 b) is triangular to polygonal. At the nodes there are often protruding spicules. The choanosomal skeleton ( Fig. 17 View FIGURE 17 c) is uni- to paucispicular, with occasional thicker (4–5 spicules) meandering spicule tracts.
Spicules. Oxeas only.
Oxeas ( Fig. 17 View FIGURE 17 d), curved, short and fat, with sharp points, 76– 83 – 91 x 3.5– 4.9 –6 µm.
Distribution and ecology. Guyana Shelf, Colombian Caribbean, shallow-water down to 24 m (holotype 1 m).
Remarks. The Guyana specimen is not growing on seaweeds like the type, but in most other aspects the similarity is convincingly large. No other species in De Weerdt’s (2000) monograph of the Caribbean Chalinidae shows the same match.
