Bottom Line: Taiwanese species of Mandarella Duvivier are compared on the basis of morphological and molecular evidence.Taiwanese records of Stenoluperus tibialis Chen, 1942, Stenoluperus nipponensis Laboissière, 1913, and Stenoluperus potanini (Weise, 1889) were based on misidentifications and represent Mandarella uenoi.The Taiwanese population previously erroneously identified as Stenoluperus pallipes Gressitt and Kimoto, 1963 is here described as a new species, Mandarella tsoui sp. n., Stenoluperus esakii Kimoto, 1969, Stenoluperus matsumurai Takizawa, 1978, and Mandarella taiwanensis Medvedev, 2012 are synonymized with Mandarella flaviventris (Chen, 1942).

ABSTRACT
Taiwanese species of Mandarella Duvivier are compared on the basis of morphological and molecular evidence. Only three of eleven morphospecies are considered to be valid. Mandarella uenoi (Kimoto, 1969) is transferred from the genus Luperus Geoffroy. Stenoluperus taiwanus Kimoto, 1991 and Stenoluperus kimotoi Döberl, 2001 are synonymized with Mandarella uenoi. Taiwanese records of Stenoluperus tibialis Chen, 1942, Stenoluperus nipponensis Laboissière, 1913, and Stenoluperus potanini (Weise, 1889) were based on misidentifications and represent Mandarella uenoi. The Taiwanese population previously erroneously identified as Stenoluperus pallipes Gressitt and Kimoto, 1963 is here described as a new species, Mandarella tsoui sp. n., Stenoluperus esakii Kimoto, 1969, Stenoluperus matsumurai Takizawa, 1978, and Mandarella taiwanensis Medvedev, 2012 are synonymized with Mandarella flaviventris (Chen, 1942).

Mentions: 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.

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.
