Description.

Male. Length 3.3-4.1 mm, width 1.3-1.7 mm. General color (Figs 39-41) bluish metallic; mouth parts, legs and abdomen yellowish; antennae dark brown but three or four basal antennomeres paler. Head weakly constricted behind eyes; antennae (Fig. 45) filiform and extremely slender, 1.2 times as body; ratio of length of antennomeres II to XI 0.6: 1.0: 1.3: 1.3: 1.5: 1.4: 1.3: 1.4: 1.3: 1.6; ratio of length to width from antennomeres II to XI 2.0: 3.2: 4.3: 4.2: 4.7: 4.6: 4.3: 4.4: 4.0: 5.3. Pronotum 1.3 times as broad long, quadrate, disc with scattered, coarse punctures, and with lateral depressions. Elytra 1.8 times as long as broad, parallel-sided, disc with dense, irregular, coarse punctures, and with depression at sides, and longitudinal ridge present along depression. First tarsomeres of front and middle legs swollen. Posterior margin of last abdominal ventrite rounded, with two small incisions, basal margin irregularly serrate. Penis (Figs 47-48) extremely slender, about 10.3 times as long as broad; parallel-sided; tectum membranous; almost straight in lateral view, weakly curved near apex, apex narrowly rounded; endophallus with one extremely elongate sclerite, sinuate in lateral view; base dorsally covered by one transverse sclerite.

Female. Length 4.3-4.7 mm, width 1.8-1.9 mm. Similar to male (Figs 42-44); ratio of length of antennomeres II to XI 0.6: 1.0: 1.3: 1.5: 1.4: 1.5: 1.4: 1.4: 1.3: 1.6; ratio of length to width from antennomeres II to XI 2.1: 3.6: 4.8: 5.4: 5.2: 5.4: 5.1: 4.9: 4.9: 5.0 (Fig. 46). First tarsomeres of front and middle legs normal and not swollen. Gonocoxae (Fig. 49) slender, each gonocoxa apically widened, apex with nine setae; gonocoxae connected at middle, base abruptly and extremely widened. Ventrite VIII (Fig. 50) weakly sclerotized; apical margin with several short setae, several long setae along lateral margin; spiculum extremely long. Spermathecal receptaculum (Fig. 51) extremely swollen; pump strongly curved; sclerotized spermathecal duct long, shallowly projecting into receptaculum.

Diagnosis.

This new species is similar to Mandarella pallipes but the latter lacks lateral depressions and ridges on the elytra.

Host plant. Adults are closely associated with Stachyurus himalaicus Hook. f. & Thomson ex Benth. ( Stachyuraceae ), which is sympatric with Dercetina itoi Kimoto, 1969 and Dercetina shirozui Kimoto, 1969.

Etymology.

This new species is named after Mr. Mei-Hua Tsou, a member of the TCRT and the first to collect this new species.

Distribution.

Endemic to Taiwan.
