Burumoseria yuae Lee and Konstantinov , new species

( Figs. 5–8 , 12–14, 17–19 )

Description. Body length 4.50–4.90 mm, width

2.30–2.60 mm. General color dark yellowish,

except antenna, meso- and metatibiae and tarsi, protarsus, outer margin of protibia, and scutellum dark brown or black; elytra widely margined with black; meso- and metasterna and metepisternum black ( Figs. 6–8 ). Antenna ( Fig. 12 ) filiform, about 0.7 times as long as body; antennomeres 4–11 slightly flattened dorsoventrally; ratios of lengths of antennomeres 2–11 about 0.9:1.0:2.3:2.0:1.8: 1.8:1.6:1.5:1.4:1.9; ratios of length to width of antennomeres 2–9 about 1.8, 2.0, 4.0, 3.1, 2.9, 2.8, 2.7, 2.8, 2.6, 3.4. Pronotum 1.48–1.66 times wider than long; disc with scattered, fine punctures, medially reduced. Elytra about 1.48–1.51 times longer than wide; disc with dense, random punctures; lateral margins parallel. Apical margin of abdominal ventrite V emarginate in middle in male. Median lobe ( Fig. 13 ) of aedeagus slender, about 6.3 times longer than wide, parallel-sided, slightly asymmetrical near apex, slightly curved in lateral view ( Fig. 14 ). Endophallus with one elongate tube-like sclerite; apex composed of anterior and posterior pairs of forked processes, with anterior processes shorter than posterior processes; anterior disc with shallow notch; posterior disc with very deep notch; base asymmetrically pointed. Vaginal palpi ( Fig. 17 ) reduced; only apex visible and weakly sclerotized; margin with 4 or 5 longer setae on top. Ventrite VIII ( Fig. 18 ) weakly sclerotized; apex narrow; apical margin slightly emarginate in middle. Spermathecal receptacle ( Fig. 19 ) strongly swollen and transverse; pump strongly curved, with swollen apex; spermathecal duct short.

Diagnosis. Burumoseria yuae is similar to B. marginipennis in color pattern, but B. marginipennis has narrower black markings on the margin of the elytron, a yellow-brown metepisternum ( Figs. 9–11 ), a more slender median lobe of the aedeagus (7.6 times longer than wide) ( Fig. 15 ), and, in lateral view, a curved apex of the median lobe of the aedeagus ( Fig. 16 ).

Etymology. This species is named after Mrs. Su-Fang Yu who explored the biology of this new species.
