Remarks

• Systematics: Ben-Dov (1993: 97,98) erroneously regarded Cryptostigma jamaicensis Qin & Gullan, 1989: 225, and Lecanopsis jamaicensis Qin & Gullan, 1989: 225 as nomina nuda that are placed with Cryptostigma inquilinum (Newstead). However, in accordance with Article 12.3 of ICZN (Fourth Edition, 2000), the mention by Qin & Gullan, 1989 of the above-mentioned names, as printed on a label, should not be regarded nomina nuda. The orbicular pores on the adult female C. inquilinum are often overlooked because they are inconspicuous, and the borders of the membranous areas do not show signs of sclerotization as in other species with orbicular pores. Hodgson (1994) and Qin and Gullan (1989) redescribed C. inquilinum, but neither study mentions the presence of orbicular pores in this species. In the study by Qin and Gullan (1989), the species is described as having no orbicular pores (as compound pores). Kondo (2010b) believed that he examined the same material, or material from the same collections as Hodgson (1994) and Qin and Gullan (1989), and that the orbicular pores were overlooked in these studies. The orbicular pores of C. inquilinum were noticed after collecting fresh material in Mexico on Acacia paniculata, and later carefully reexamining the type material listed above. (Kondo, 2010b) The ending of the specific epithet "inquilina" was changed to "inquilinum" in order to match the neuter gender of the generic ending -stigma, in accordance to the ICZN code (article 30.1.2.) in ondo, 2010b.
• Structure: "Color in life of different shades of light reddish or yellowish brown, often varying to hint of lavender purple brown; color of alcoholic specimens dorsally pale grayish brown, with somewhat distinct linear transverse mottling of dark brown, tiny blackish flecks along margin, brown area around anal plates, small white spots at stigmatic area, ventrally with marginal band of dull brown, anterior 2 thirds of surface yellow cream, shading off to brown at edges, ventral abdominal segments about same color as dorsum; whole venter variously mottled, flecked with dark color" (Morrison, 1922). Specimens collected in Mexico with a rugose dorsum with clearly visible dorsal segmentation; color ranging from yellow to pink, with anal plates darker, orange brown to red brown, with a conspicuous white wax on each stigmatic area. (Kondo, 2010b) The first-instar nymph of C. inquilinum can be diagnosed by the following combination of features: (i) dorsal setae present in 2 longitudinal rows of about 5 pairs, (ii) anterior and posterior stigmatic clefts each with 1 stigmatic seta, (iii) with 7-9 marginal setae between anterior and posterior stigmatic setae, (iv) antennae 6 segmented, (v) with 1 pair of ventral submedian setae on posterior 3 abdominal segments, (vi) each anterior stigmatic furrow with 7-8 pores, each posterior furrow with 7-9 pores, and (vi) ventral submarginal setae flagellate. (Kondo, 2010b)
• Biology: Living on bark of the host plant beneath a blackish shelter constructed by the ant Crematogaster brevispinosa Mayr (Newstead, 1920). Attended by the ant Azteca longiceps in Panama (Morrison, 1929). Attended by the ant, Pseudomyrmex viduus (F. Smith), on the internodes of Triplaris weigeltiana branches, and cohabiting with the pseudococcid Farinococcus multispinosus Morrison (Ward, 1999).
