Holotype, ♂, Western Australia, Perth , 14.x.2001, ( WAMP) . Paratypes

- 1 ♂, 4 ♀, same data as holotype, (4 JHAC, 1 WAMP) ;

- 1 ♂, 1 ♀, Western Australia, Yellowdine [400 km E of Perth], 16.x. 2001, ( JHAC) .

Description of the holotype

Body. – Measurements (in mm):TL 2.3, EW 1.4. Body short, oval (Fig. 22); head black; pronotum black, with intermixed, long yellow and brown setation; elytra black with brown, apical part, covered with sparse brown and yellow setation; antennae black; legs brown.

Head. – Coarsely punctate, sparsely covered with intermixed yellow and brown setation. Palpomeres dark brown. Eyes large, with yellow microsetae. Ocellus present on front. Antennae filiform, black, with short, yellow setation, composed of 11 antennomeres (Fig. 23).Antennal club with 5 antennomeres.

Pronotum. – Shiny, covered by long brown and yellow setation, yellow setation forming small spots, laterally coarsely punctate, black, lateral margins of pronotum smooth.

Scutellum . – Black, shiny, triangular, without setation.

Elytra. – Shiny, black, with brown apical part, covered by sparse brown setation with multiple narrow transverse bands of yellow setae.

Ventralsurface. – Epipleuron black, covered by short, yellow setation. Mesosternum and metasternum covered with yellow setation, finely punctate.

Variability. – The two specimens from Yellowdine are slightly different by the lighter cuticle and large brown apical part of the elytra. Measurements (in mm): male: TL 2.3; female: TL 3.0.

Differential diagnosis. – The new species is similar to Trogoderma koy (Ślipiński & Zhou,2023) ,based on the lmultiple transverse bands of light setae on the elytra. but differs from it by the structure of the black antennae and male genitalia.

Etymology. – Toponymic, named according to the type locality, Perth city.
