Holotype: ♂ "Shan States Mandets/ 1001 Asia Sericini spec." (MNHN).

Description.

Length of body: 7.8 mm; length of elytra: 5.9 mm; maximum width: 4.8 mm. Surface of labroclypeus and disc of frons glabrous. Smooth area anterior to eye twice as wide as long. Eyes moderately large, ratio of diameter/interocular width: 0.56. Ratio of length of metepisternum/metacoxa: 1/1.64. Metatibia short and wide, ratio width/length: 1/3.08; basal group of dorsal spines of metatibia at first third of metatibial length. Ventral distal spine of metatibia inserted shortly behind middle of ventral margin of metatibia and longer than the long metatarsomere 1.

Aedeagus: Fig. 27 E–G. Habitus: Fig. 27H.

Female unknown.

Diagnosis.

Tetraserica giulianae sp. n. is similar to T. angkhangensis Kobayashi, 2017 in shape of the aedeagus, but the new species differs by the basal lobe of left paramere being as long as the ventral lobe, rather than half its length.

Etymology.

The new species is named in honour of our friend Giuliana Caturegli (Rome) (noun in genitive singular).
