Aedeagus: Fig. 16 A–D. Habitus: Fig. 16E.

Variation.

Length of body: 8.4-9.8 mm; length of elytra: 6.5-7.3 mm; maximum width: 5.2-5.8 mm. Female: Eyes as large as in male; antennal club composed of three antennomeres, as long as remaining antennomeres combined.

Diagnosis.

Tetraserica fulleri sp. n. differs from all other Tetraserica species in having long parameres and a long median phallobasal lamina, and by the simple left paramere being wide for its entire length (at middle nearly as wide as apex of phallobase; lateral view).

Etymology.

The new species is named after its collector, E Fuller (noun in genitive singular).
