Sangicoccus Reyne

Haematococcus Reyne, 1961: 127 .

Sangicoccus Reyne, 1965: 180 (replacement name).

Type species Haematococcus obtusispinus Reyne, 1961 , by original designation.

Sangicoccus was introduced by Reyne as a replacement name for Haematococcus , already in use in the Protozoa. At that time Sangicoccus included two species, S. obtusispinus Reyne and S. truncatispinus Reyne , both off Cocos nucifera (Palmae) from Irian Jaya, Indonesia. Williams & Watson (1990) noted that Reyne reported much sooty mould, suggesting that they produced large amounts of honeydew, and also that they were ant attended. Below we describe two further species, one from Camiguin Is., Philippines, also off Cocos , and the other from Sulawesi, Indonesia, off rotan palm (Arecaeae).

Generic diagnosis. Body of adult female on microscope slide broadly oval, membranous. Ven te r. Antennae short, 3 segmented, gently tapering. Frontal lobes present, well developed. Labium apparently unsegmented, with minute setae on tip. Loculate disc pores, each with 5–10 loculi, scattered over most of surface, or in marginal groups; absent medially on head, thorax and anterior abdominal segments. Legs not well developed, short; trochanter and femur usually fused; hind coxa and femur with large, irregularly-shaped translucent pores on posterior surfaces. Macrotubular ducts long and narrow, each with wide sclerotized area surrounding orifice; present sparsely on abdomen, each inner ductule shorter than length of outer ductule, terminating in a circular gland. Instead of cruciform pores modified microtubular ducts present in a submedial band. Setae few, short and pointed. Dorsum. Marginal setae spine-like, conical, usually truncate, sometimes bluntly pointed; present in large groups around margin, each on an area of sclerotised derm. Dorsal setae numerous, of 2 types, one type wide spine-like, and other narrow spine-like. Anal lobe segment and anal lobes displaced onto dorsum and surrounding anal ring. Anal lobes barely discernible, each with 2 long flagellate setae and 2 spine-like setae. Anal ring sclerotized, with a small number of pores in a single row, plus 6 anal ring setae, each longer than diameter of ring. Cauda apparently represented by an undetached lobe anterior to the anal ring. Disc pores each with 5–7 loculi, few and scattered on posterior abdominal segments and forming a sparse marginal/submarginal band. Macrotubular ducts absent. Small and short microtubular ducts present, scattered.

Comments. Pedroniopsis Green , described from Sri Lanka, also possesses 3-segmented antennae and has truncate-conical setae. However, these setae are not in marginal groups as in Sangicoccus .
