Remarks

• Structure: Female test is highly convex, rounded anteriorly, tapering posteriorly. It is light brown in color with white strands of wax in spiracular furrows. Female body is pear shaped (Lambdin & Kosztarab, 1977a). The adult female of C. catenarius is characterised by the following combination of character-states: (i) anteroventral sclerotizations absent; (ii) three finely spinose setae present along inner margin of each anal lobe; (iii) dorsal fleshy setae on anal lobes bullet-shaped; (iv) posteroventral seta on each anal lobe absent; (v) dorsum with three sizes of 8-shaped pore, all quite small, larger pore restricted to near stigmatic pore bands; (vi) 8-shaped pores on dorsum randomly distributed, not in whorls or in a reticulate pattern; (vii) smallest 8-shaped pores on dorsum in a transverse band across apex of each stigmatic pore band, dividing each large apical group of spiracular disc-pores into two halves; also present on posterior abdominal segments; (viii) stigmatic pore bands with abundant spiracular disc pores, forming a large apical group that sometimes extends a short way medially; (ix) cribriform plates present in a submedial group of 5–7 on each side of abdominal segment IV; (x) leg stubs present; (xi) stigmatic pore bands bifurcated; (xii) tubular ducts of two sizes, broadest ducts restricted to medially on posterior abdominal segments, narrower ducts abundant elsewhere; (xiii) multilocular disc-pores present in broad bands across abdominal segments II–VI and medially on metathorax; (xiv) ventral 8-shaped pores extending medially well past antennae and spiracles, and (xv) antennae without either a cone-like apex or a setal cavity.

• Biology: LePelley (1968) states there is only one generation per year. The females produce an average of 900 eggs.
• Economic Importance: Le Pelley (1968) states that this scale is thought to have spread from indigenous plants to coffee and since its description in 1957 it has become a serious pest. Chemical control can be obtained with one per cent oil emulsion with soap, but better results can be obtained with Diazinon, Malathion and Parathion.
