Etymology
. The specific name
makua
is a noun in apposition refers to a human ethnic group living in
Mozambique
.
Diagnosis
. Chitinous joints passing across gymnocyst and below opesia in outer zooids at bifurcation (zooids C and D); zooids with 3 outer and 1–2 inner distal spines; scutum slender and flattened, branched twice, sometimes forked at tips, occupying half to two thirds of zooidal length; distolateral avicularia absent; frontal avicularia variable in size, aquiline; ovicell with small pseudopores linked by internal sutures.
Description
. Colony erect, with branches comprising 5–11 zooids. Internodes with alternating zooids, slightly curved, with new branches directed inward. Chitinous joints passing across gymnocyst in both outer (zooids C and D) and inner zooids (F and G) at bifurcation. Autozooids almost cylindrical, tapering proximally. Oval opesia occupying half to three fifths of zooidal length; cryptocyst deep and smooth, forming a very narrow strip around opesia. Scutum slender, flattened, branched twice, sometimes forked at tips, inserted at midline of inner opesial border and spreading over half to one third of frontal membrane. Distal spines unbranched; 3 outer and 1–2 inner; proximalmost spines directed slightly forward; axial zooid with 5 spines: 2 lateral pairs and 1 mid-distal. Distolateral avicularium absent. Frontal avicularia monomorphic, of variable size, aquiline with slightly curved rostrum directed forward; mandible triangular, curved, hooked distally. Vibracular chamber sometimes present on basal surface of zooid, inconspicuous in frontal view; chamber of vibraculum almost trapezoidal, with rhizoidal foramen at its outer proximal corner; setal groove transverse to internode axis, straight, with smooth seta longer than one autozooid. Single axial vibraculum without rhizoidal foramen. Rhizoids tubular, smooth. Ovicells almost globular, with regularly spaced pseudopores linked by internal sutures; ovicelled zooids with 2 outer and 1 inner distal spines.
Remarks
.
Cradoscrupocellaria makua
n. sp.
resembles
C. lagaaiji
n. sp.
in the shape of the autozooids, position of joints and number of distal spines, but differs in the shape of the frontal avicularia and size of the scutum.
Distribution
. Indian Ocean:
Mozambique
