Material
MALAYSIA: MSL BRY016, Kampung Kuala Temoyong, Langkawi, found among fishing debris.
Description
Colony erect, rigidly calcified, bushy ( Fig. 9A View Fig ), comprising bifurcating, bifoliate, strap-like branches, about 2.2–2.5 mm wide, with approximately a dozen series of zooids across width of branch.Autozooids small, rounded hexagonal, longer than wide, 0.29–0.38 mm long by 0.19–0.24 mm wide, distinct with deep interzooidal grooves, frontal shield convex, a slight umbo sometimes developed centrally, densely granular in surface texture, with large areolar pores covering most of surface; primary orifice more or less equidimensional, about 0.08 mm long, a shallow U-shaped sinus separated from anter by small condyles ( Fig. 9E View Fig ); secondary orifice somewhat transversely elliptical, a subcircular spiramen separated from secondary orifice by a calcified bridge in mature zooids ( Fig. 9 View Fig F–G). Gonozooids larger than autozooids, with a broad, shallow orifice separated from a wide spiramen by a deep calcified bridge with a process on proximal edge.Adventitious avicularia ( Fig. 9F View Fig ) developing on frontal shield of autozooids, often laterally to spiramen but occasionally more proximally, generally one or two per autozooid, sometimes absent, orientated variously; rostrum high gothic arch-shaped; cross-bar uncalcified; opesia rounded, a little wider than rostrum. Vicarious avicularia sporadically distributed ( Fig. 9D View Fig ), longer than autozooid, about 0.57 mm long by 0.21 mm wide; rostrum elongate, spatulate with a distal shelf; crossbar uncalcified; opesia roughly semicircular with a sloping cryptocyst-like proximal edge; frontal shield with areolar pores similar to those of autozooids. Kenozooids present along some branch edges.
Remarks
Found among debris discarded from a fishing net, Adeonella lichenoides is the only rigidly erect bryozoan collected in either Langkawi or Penang during the fieldwork in October 2013. This species is distributed throughout the Indo-West Pacific region ( Hayward 1988).
