Zaratus hidekun new species

(Figs. 1, 3, 7, 8)

Diagnosis. Recognized by the characters mentioned in generic diagnosis and form of the male genitalia, especially a row of long setae on the left side of the male genital capsule (Fig. 7). This new species can be distinguished from the other congener, Z. repandus Distant, by the amber coloration, wholly shiny pronotum, different pattern of white maculae on the corium and clavus, and weakly constricted anterior part of the hemelytron.

Description. Male: Body generally amber brown, somewhat tinged with red, elongate, rather small in size; dorsal surface polished, shining, with very short, silky, semierect setae. Head shiny, rather vertical; eye small; vertex twice as wide as an eye in dorsal view. Antennae pale brown, almost linear. Labium shiny brown, slightly exceeding apex of mesocoxa. Pronotum polished, rounded, with sparsely distributed, very short, silky setae; collar broad, about as thick as antennal segment I; mesoscutum and scutellum covered with pronotum; pleura amber brown, except for darkened median protuberance of ostiolar peritreme; evaporative area ivory white. Hemelytron weakly shining, with four variable, white maculae each on anterior and posterior parts of clavus, and anterior corner and posterior part of corium (Fig. 1 F); vestiture on hemelytron very sparse and short; cuneus chestnut brown; membrane somber pale brown. All coxae and legs amber brown, except for yellowish meso- and metacoxae. Abdomen shiny amber brown; male genital segment widely darkened. Male genitalia (Fig. 7): Left lateral side of genital segment with a row of long, noticeable setae. Phallotheca L-shaped, blunt-tipped. Endosoma slender, weakly curved, with short apical spine; secondary gonopore developed. Female: Unknown.
