Diagnosis.

This species is similar to Paridea (Paridea) costata with the metallic blue elytra but differs in possessing a yellowish brown lateral margin of each elytron, the yellowish brown head and pronotum, and the unmodified first tarsomeres of males.

Males.

Length 4.9 mm, width 2.4 mm. General color yellowish brown (Figs 52-54); antennomeres IV-XI darkened; elytra metallic blue, but basal margin, base to apical 1/3 of lateral margin yellowish brown; metathoracic ventrites metallic blue. Elytra with one longitudinal costa arising from humerus, reduced in some individuals. Eighth abdominal tergite (Fig. 62) weakly sclerotized but apex well sclerotized, transverse and wide, apical margin rounded, with dense long seta along apical margin. Penis (Figs 58-59) wide, apically tapering, apex slightly asymmetric and pointed, slightly curved near apex and apex narrowly rounded from lateral view; endophallus with two visible sclerites, apically curved and pointed, one smaller.

Females.

Length 5.5-6.1 mm, width 3.0-3.2 mm. Similar to male; apical margin of last abdominal ventrite smooth, not modified. Gonocoxae (Fig. 60) slender, apex of each gonocoxa with seven setae from apical 1/7 to apex; connection of gonocoxae extremely slender, base slender. Sternite VIII (Fig. 61) weakly sclerotized; apex wide, apical margin emarginate at middle, surface with longer setae near apical margin and shorter setae on apical margin, spiculum long. Spermatheca (Fig. 63) weakly sclerotized; receptaculum slightly swollen; pump short and wide, strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.

Distribution.

The species occurs in eastern and southern Taiwan (Fig. 64).

Host plant.

Cucurbitaceae : Momordica cochinchinensis (Lour.) Spreng.
