Remarks

• Systematics: The adult female of C. reticulolaminae can be diagnosed by the following features: (i) presence of numerous subcircular sclerotic pores arranged in a reticulate pattern, (ii) dorsal setae sharply to bluntly spinose, with a swollen or spatulate apex, (iii) dorsal microducts heavily sclerotized, with a deep outer ductule broadened near duct opening, (iv) preopercular pores absent, (v) presence of about 4 setae on surface of each anal plate, (vi) marginal setae not differentiated from dorsal setae, (vii) stigmatic sclerotization each with 3 stigmatic setae, (viii) antennae 1 segmented, reduced to a small round sclerotized plate (ix) ventral microducts with a swollen inner ductule, (x) multilocular disc-pores restricted to a small group on each side of vulva, (xi) legs vestigial, setose, and (xii) ventral tubular ducts absent. (Kondo, 2010b) The first-instar nymph of C. reticulolaminae can be diagnosed by the following combination of features: (i) dorsal setae present in 2 longitudinal rows of 5 pairs, (ii) each anterior stigmatic cleft with 3 stigmatic setae; each posterior cleft with 4 or 5, (iii) with 9 or 10 marginal setae between anterior and posterior stigmatic setae, (iv) antennae 5 segmented, (v) with pairs of submedian abdominal setae on last 3 abdominal segments, (vi) anterior stigmatic furrows each with 4 or 5 pores, posterior furrows each with 5-7 pores, (vii) ventral microducts with a long inner ductule, and (viii) dorsal surface of anal plates of a shingled texture. C. reticulolaminae is the only species in the genus with first-instar nymphs that have ventral microducts with a very long inner ductule. (Kondo, 2010) Despite the resemblances of adult female C. reticulolaminae to those of Myzolecanium, the first-instar nymphs of C. reticulolaminae are typical of Cryptostigma, with 5-segmented antennae (5- or 6-segmented antennae in Cryptostigma, and always 6-segmented antennae in Myzolecanium); absence of setae near each coxa (a seta always present next to each coxa in Myzolecanium); presence of 1 or 2 membranous folds just anterior to anal plates and with folds showing some sign of sclerotization (no membranous folds just anterior to anal plates in Myzolecanium); and with 3 pairs of ventral submedian setae posteriorly on abdomen (usually 3 pairs in Cryptostigma but always 6 pairs in Myzolecanium). (Kondo, 2010b)
• Structure: "Specimens varying in size and shape, average length 5 mm., width 4.5 mm., height 2.5 mm., deeply invaginated beneath in the abdominal region; color of alcoholic specimens dark reddish brown with blackish infusion along margin and anterior to anal plates; body surface smooth, rather shining, bearing numerous tiny pits corresponding in position to sclerotic plates of derm" (Morrison, 1929).

• Biology: Attended by the ant Azteca longiceps in Panama (Morrison, 1929).
• General Remarks: Good description and illustration of the adult female given by Morrison (1929).
