Parlatoria Targioni Tozzetti

Parlatoria Targioni Tozzetti, 1868: 735.

Type species.

Parlatoria orbicularis Targioni Tozzetti, subsequently designated by Leonardi (1899: 208).

Generic diagnosis.

Female scale. Various colors, oval to elongate, with exuviae terminal, often occupying greater part of scale.

Male scale. Elongate and smaller than the female.

Adult female. Female body nearly round or broadly ovate, and the widest at metathorax or abdominal segment I. The body free segments distinct but not strongly produced, and membranous except for the pygidium. Antennae with one or two setae. Prosomatic tubercles present or absent. Anterior spiracles with disc pores, the posterior spiracles without disc pores. Derm pocket present or absent between the posterior spiracle and body margin. Peribuccal granulations present or absent. The pygidium rounded or rather triangular. Three pairs of lobes well developed, unilobate, usually notched, median lobes not yoked; marginal macroducts of pygidium, one present or absent between the median lobes, one between the median and second lobes, and also between the second and third lobes. Two or three fimbriate plates present between lobes, then extend to the whole lateral margin of the pygidium, and each with one microduct. The fourth and fifth lobes often present, sclerotized or replaced by a membraneous fimbriate plates. Submarginal dorsal ducts usually present, scattered in a broad, continuous, irregular row on each side of the abdomen. Submedian dorsal ducts present or absent. Anal opening positioned about centre of pygidium. Four or five groups of perivulvar pores present (Adapted from McKenzie 1945, Takagi 1969, Williams and Watson 1988, Henderson 2011).

Remarks.

This genus Parlatoria , like other groups of the subfamily Aspidiotinae has an ovate body, and the second lobes are not divided into two lobules. Fringed plates are present between the lobes. Parlatoria is distinguished from other genera, especially Parlagena McKenzie, 1945, and Parlatoreopsis Lindinger, 1912, by having fringed plates across two sides of the prepygidial abdominal segments.
