Type material.

Holotype. ♂, Korea: Wanju-gun, 14.xi.2014, 35°49'45.64"N, 127°02'27.20"E, leg. H.S. Shim, genitalia slide no. 15315, DNA barcode GenBank accession no. MT447100 (NAS). Paratypes. 3♂, Korea: Tongyeoung, 17.i.2020, 34°50'58.58"N, 127°26'51.79"E, leg. J.-H. Song, genitalia slide no. 21366-21968, DNA barcode GenBank accession no. MT447101, MT447102, and MT447103 (NAS).

Diagnosis.

Galleria similis sp. nov. (Figs 2 , 4 , 6 ) is very similar to G. mellonella (Figs 1 , 3 , 5 ) but can be distinguished by a square discal cell of its hindwing venation (Fig. 6 ) and the different shape of male genitalia (Fig. 4 , G. similis : valva shorter and wider, concave at outer margin). Galleria similis sp. nov. had 15, one and four diagnostic characters from 658 bp of partial COI, 613 bp of partial CAD and 423 bp of partial wg gene region, respectively (Table 4 ). Our study showed that morphological and molecular characters can be used to resolve the status of cryptic species, G. mellonella and G. similis . A cryptic species was suggested by the unusually high genetic distances within specimens originally identified as G. mellonella .

Description.

Adult. Male (Fig. 2 ). Head: vertex densely clothed with gray hair-like scales; labial palpus three-segmented. Thorax: Light brown; notum covered with gray scales. Legs with femora, tibiae, and tarsi clothed with light gray piliform scales; tarsi apical and medial spurs covered dark-brown scales. Wingspan 21.5-32.0 mm. Forewing (Fig. 6 ) narrow, costa straight at base and gently curved beyond 4/5, termen concave; tornus pointed, 9 separate veins originating at the discal cell; Sc terminating at 4/5 costa; R5 originated at R4, M1 and M2 parallel; M2, M3 originating at distal corner of discal cell; Cu1 and Cu+A1 parallel, ground color yellowish white with gray and some dark overscaling. Hindwing (Fig. 6 ) discal cell square, L/W ratio 1.72; costa straight, apex straightly curved to termen; Sc straight to 3/5 costa; R1, R2 and R3 present; R1 and R2 terminating at apex; M2 originating at 1/5 M3; CuA1 and CuA2 parallel; A1 originating at 4/5 Cu2. Hindwing covered with dark-brown scales; postmarginal part present with short light brown hairs. Abdomen: Male genitalia (Fig. 4 ) with uncus concave and hooked; tegumen wide at base; gnathos long; valva short and wide, costa straight, termen relatively concave, small setae present sparsely on outer and inner surface; vinculum narrower than gnathos; juxta heart shaped; saccus very short and slender; phallus slightly short and thick, vesica with short setae, ductus ejaculatorius present.

Female. Unknown.

Distribution.

Korea.

Etymology.

Named from the Latin similis meaning “similar”, which refers to the similar morphological characters with G. mellonella .
