Type species: Marsipococcus proteae (Brain)
by present designation
accepted valid name
- Systematics: Proteacoccus differs from Marsipococcus as follows (character-states Marsipococcus species in brackets): (i) dorsum without radial lines extending medially from margin (radial lines present); (ii) ventral tubular ducts absent (a group of ventral tubular ducts present on either side of the genital opening); (iii) each stigmatic cleft with the 2 stigmatic spines placed at base of the cleft (with 1 spine on the anterior and other on the posterior margin of each cleft); (iv) dorsum with minute pores anterior to or on either side of anal plates, preopercular pores absent (minute pores absent from this position, preopercular pores present (M. marsupialis) or absent (M. ulubendulensis)); (v) each anal plate with a subdiscal seta (subdiscal setae absent); (vi) multilocular disc-pores mostly with 10 loculi (multilocular disc-pores, when present (in M. marsupialis), each with 5 or 6 loculi); (vii) anal sclerotization absent (anal sclerotization present, extending around anterior margin of anal cleft); (viii) marginal setae short, or bluntly pointed, shorter than stigmatic setae (marginal setae strongly spinose and pointed, subequal to or longer than stigmatic setae), and (ix) tibia and tarsus showing distinct segmentation (tibia and tarsus fused, without segmentation).Marsipococcus proteae and M. durbanensis awere therefore removed from Marsipococcus and placed in the new genus Proteacoccus by Łagowska & Hodgson., 2019.
- Structure: Slide-mounted adult female: body broadly oval, moderately convex; stigmatic clefts distinct, each with or without a sclerotized inner margin; anal cleft rather short, about 1/6th body length. Dorsum becoming sclerotized at maturity, with obscure areolations. Dorsal microducts not noted. Preopercular pores possibly absent, replaced by obscure minute pores anterior to and on either side of anal plates. Submarginal tubercles few or absent. Dorsal setae minute, bluntly pointed and sparse. Dorsal tubular ducts absent. Anal plates slightly longer than wide, each plate with 3 apical setae plus a subdiscal seta near inner margin. Marginal setae very short, cylindrical to slightly pointed, few, set far apart. Each stigmatic cleft with 2 spinose setae, each stout and slightly swollen apically, placed at the base of each cleft. Venter with multilocular disc-pores, mostly each with 10 loculi, present anterior to genital opening and across most other abdominal segments. Spiracular disc-pores, mostly each with 5 loculi, few, in narrow bands between stigmatic clefts and spiracles. Long setae anterior to genital opening reduced to 1 pair on segment VII. Ventral tubular ducts absent. Antennae 7 or 8 segmented. Legs reduced, without a tibio-tarsal articulatory sclerosis; tarsal digitules similar, both with a broadly expanded apex. Claw with a minute denticle; claw digitules both narrow. (Łagowska & Hodgson, 2019)
