Diagnosis
Paridea (Paridea) costata is recognized by the black vertex, presence of one black spot on the pronotum, the metallic blue elytra, and the swollen first tarsomeres of front and middle legs of males.
Males
Length 4.5–4.7 mm, width 2.2–2.4 mm. General color (Figs 34–36) yellowish brown; antenna blackish brown but three basal antennomeres paler; vertex with one big black spot; pronotum with a moderate black spot near center; scutellum and elytra bluish black; metathoracic ventrites black; tibia and tarsi dark brown; femora darkened except bases and apices. Elytra with one longitudinal costa arising from humerus, reduced in some individuals. Median lobe at fifth abdominal ventrite deeply depressed. Eighth abdominal tergite (Fig. 51) weakly sclerotized but apex well sclerotized, transverse and wide, apical margin emarginate at middle, with dense long setae along apical margin. First tarsomeres of pro- and mesotarsi swollen (Fig. 49). Penis (Figs 44–45) wide, apically tapering, apex truncate, slightly curved near based from lateral view; with one pair of elongate processes extending from near apex to middle, base curved upwards from lateral view; external process large and wide, lateral margin irregular from middle to apex, with a small process at middle of lateral margin; endophallus without visible sclerites.
Females
Length 4.7–4.9 mm, width 2.5 mm. Similar to male; apical margin of last abdominal ventrite smooth, not modified. Gonocoxae (Fig. 46) slender, apex of each gonocoxa with seven or eight setae from apical 1/7 to apex; connection of gonocoxae extremely slender, base slender. Sternite VIII (Fig. 47) weakly sclerotized; apex wide, apical margin emarginate at middle, surface with dense long setae on apical margin, spiculum short. Spermatheca (Fig. 48) strongly sclerotized, disk with dense transverse grooves; receptaculum narrower than pump; pump short and wide, strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.
Distribution
China (Gansu, Jiangxi, Sichuan, Zhejiang), Taiwan. It is uncommon but widespread in Taiwan (Fig. 20).
Host plants
Cucurbitaceae: Thladiantha nudiflora Hemsl. ex Forbes & Hemsl.
