Remarks

• Systematics: The adult female of C. chacoensis can be diagnosed by the following combination of characters: (i) dorsum with 25-33 complex orbicular pores, (ii) unilocular and bilocular dorsal microducts present, (iii) with about 18 setae on surface of each anal plate, (iv) preopercular pores absent, (v) marginal setae sharply spinose, often with swollen bases, and (vi) presence of ventral tubular ducts. C. chacoensis appears most similar to C. saundersi Laing, but the following features separate the two species (characters on C. saundersi in brackets): (1) only 22-23 complex orbicular pores present (60 or more); (2) multilocular pores absent near antennae (a multilocular pore present next to each antenna); and (3) ventral microducts arranged randomly (arranged in transverse rows). (Kondo, 2010b) The first-instar nymph of C. chacoensis can be diagnosed by the following features: (i) dorsal derm rugose, (ii) dorsal setae present in 2 longitudinal submedian rows of about 11 pairs of setae, (iii) stigmatic setae totalling 1 or 2 per stigmatic cleft, (iv) 8-10 marginal setae present between anterior and posterior stigmatic setae, (v) antennae 6 segmented, (vi) with 5 pairs of ventral submedian setae on abdomen, (vii) spiracular disc-pores with 3-8 loculi, and (vii) each anterior and posterior spiracular furrow with 6-9 pores. (Kondo, 2010b)
• Structure: Young adult females reddish orange, becoming purplish brown at maturity; anal plates and surrounding area distinctly darker than rest of dorsum. Mounted material: body outline oval to elongate oval, constricted at stigmatic areas. (Kondo, 2010b) Immature insects yellowish. (Kondo, 2010b)
• Biology: Cryptostigma chacoensis found inside nests of Plebeia sp. and Schwarzula timida Camargo and Pedro (D.W. Roubik, pers. comm. in Kondo, 2010b).Cryptostigma chacoensis together with C. melissophilum are the only species of Coccidae known to be tended by stingless bees and harboured within their nests. (Kondo, 2010b).
