Remarks

• Systematics: urn:lsid;zoobank.org:act:D24B8607-E2C7-418D-AE73-8E73C558454B Originally described in Cermeli & Garaud-Pouey (1997:115-123) as Capulinia sp. near jaboticabae. Capulinia jaboticabae is very similar morphologically to C. linarosea, but has smaller legs, generally shorter antennae, shorter and less robust setae, even thoug some specimens of C. jaboticabae have the same body size. Also, the larger (wider) of two kinds of microducts has a squarish distal end on C. jaboticabae compared with a narrower asymmetrical end on C. linarosae. (Kondo, Gullan & Cook, 2016) First-instar nymphs share the following morphological characteristics with the nymphs of C. luma, C. orbiculata and C. sallei: (i) 6 segmented antennae; (ii) dorsal setae all of one type, spinose with rounded to bluntly pointed apex, although varying in setal shape among species, (iii) marginal setae of same type and distributed several per segment on head and thorax and in a double line on the abdomen (ie. a pair of setae on each side of each segment; (iv) anal lobes poorly differentiated and not sclerotized; (v) loculate pores restricted to cavity laterad to each priable; (vi) paired claw and tarsal digitules similar to each other. First-instar nymphs can be distinguished from the nymphs of C. luma (characteristic os C. luma in parentheses) by having (i) 2 longitudinal lines of robust spinose setae on the dorsal abdomen, excluding marginal rows (4 lines); (ii) 1 loculate pore present immediately lateral to each peritreme (2-3); (iii) 4 longitudinal lines of setae on ventral abdomen (6 lines); and (iv) microtubular ducts present on dorsum (absent). the nymphs differ from those of C. orbiculata and Cuban specimens of C. sallei (characteristics of the later 2 in parentheses) in having all dorsal setae broad for full length with a rounded apex (tapering to a rounded or bluntly pointed apex).
• Structure: Body light yellow, covered in a mass of loose white cottony wax. Mounted female body oval, becomig more rounded a maturity, 0.8-1.9 mm long, 0.6-105 mm wide. Segmmentation apparent on abdomen and usually on thorax. Unmounted first-instar nymph elongate oval; whitish just after hatching, becoming yellowish.
• Biology: Occurs on the trunk, stems and foliage of its host. Biology studies on P. guajava by Chirinos et al. (2004) showed that the female undergoes two nymph stages and the male four. They also noted that eggs lasted approximately 8 days and, in the case of the female, this completed the nymph phase (first and second nymph phase) after 14 days, while it reached approximately 56 days of longevity as an adult.
• Economic Importance: Two years after its appearance in Venezuela this pest, devastated more than 600 ha of orchard in Maracaibo’s high plain, Zulia state (Maracaibo, Mara and Páez municipalities) (Cermeli and Geraud- Pouey, 1997), considered by that time the most important guava producing area in the country. The action of parasitism by i>Metaphycus sp., combined with natural control factors such as depredators and fungi entomopathogenic (in areas where the climatic conditions favor the latter), C. linarosae/i> populations could maintain to tolerable levels. (Chirinos, 2004)
