Plataspidae (Hemiptera: Heteroptera) is a moderately species-rich family within Pentatomoidea comprising about 59 genera and nearly 500 described species restricted to the Old World (Davidova-Vilimova and Stys, 1980; Ahmad and Moizuddin, 1992; Lin and Zhang, 1993; Ren, 2000; Xue and Liu, 2002; Davidova-Vilimova, 2006), with one species introduced to the Hawaiian Islands (Beardsley and Fluker, 1967) and another to North America (Eger et al.
DIAGNOSIS: Recognized within Plataspidae based on the combination of the following characters: body of medium size (6-9 mm), ochraceous with black pattern, broad, dorsally and ventrally convex (Fig.
ETYMOLOGY: Derived from the Latin noun labrum, referring to the enlarged labrum of the included species, and the Greek adjective [pi][lambda][alpha][tau][zeta] (Latinized as platys) meaning "wide, broad", a compontent occurring in several generic names in the family Plataspidae.
SYSTEMATIC PLACEMENT" The single attempt to define higher categories within Plataspidae in global perspective was presented by Jessop (1983), who recognized three supposedly monophyletic "genus groups" without assigning subfamilial or tribal status to them.
COMPARISON WITH SIMILAR GENERA: The highly elevated labrum is a peculiar apomorphy of the new genus which only occurs in very few genera of Plataspidae, and is also exceptional in other heteropteran families.
The specialized female terminalia possibly represent a synapomorphy supporting sister group relationship between these two genera; we did not see similar modification in any other genera of Plataspidae known to us.
as is indicated by the presence of an unpaired dorsal and a pair of ventral conjunctival appendages of the phallus and the plesiomorphic structure of female terminalia (valvifers VIII, laterotergites IX as usual in Plataspidae, not produced posteriorly) (Ahmad and Moizuddin, 1992).
