Type locality: Vietnam

Holotype: MNHU (♂)

Description. Head. Clothed brownish cream ochreous scales. Ocellus well developed. Vertex and dorsal part of frons clothed with anterior and forward projected cream brownish ochreous scales, base of the frons with small appressed upwardly projected light brown ochreous coloured scales. Labial upcurved covered with ochreous brown scales; first segment brownish ochreous; second segment long and curved, cream interspersed with dark brown scales along dorsal margin from base to middle apex; small third segment with pale brown, concealed within second segment. Antenna filiform covered with brownish orange scale with intersegmental short cilia. Chaetosemata present.

Thorax. Pronotal collar, tegulae, mesonotum, and posterior crest cream mixed with brown cream ochreous interspersed with brown scales; middle legs with a pair of tibial spurs; hind tibia covered with dense, whitish ochreous scales in male, inner margin with a tuft of long, brownish ochreous coloured long hair pencil, originating from base of hindtibia. Wings: Forewing (wingspan 12–14 mm; n= 13) subrectangular, pale brownish grey ground color pale with cream costal and terminal areas; in dorsal third of wing brownish; strigulation brownish grey, costal fold medium, clothed with brownish ochreous scales, costal terminal areas more cream, basal half of wing with ochreous scale; termen fairly oblique, straight; dorsal third of wing brownish; median fascia slender, uniformly broad, ferruginous medially, edged brown; subapical blotch brownish with grey brown spots; terminal suffusion weak marked by brown median veins. Cilia cream, brown at tornus. Hindwing brownish grey, cream towards base, with brownish venation; cilia paler than wing. Wing venation: Forewing with all the veins separated beyond the discal cell, CuP indistinct. Hindwing with Rs and M1 connate basally, M3 and CuA2 stalked, CuP distinct.

Abdomen. Covered with dark brownish ochreous scale dorsally, ochreous grey ventrally and tufts of hairs apically. Male genitalia. Uncus long, broad base, apex bilobed; tegumen subrectangular, dorsolaterally with small angled shoulders; gnathos strongly sclerotized bands, arising near middle of tegumen, slightly widened towards apex and gnathal hooks well developed; valva membranous, symmetrical; transtilla sclerotized, spinose plate; juxta medium, subtriangular, bilobed apex; sacculus moderately sclerotized, basely broad and narrow apex, with moderately dense sockets basally, continued as row of short setae reaching base of cucullus; vinculum membranous. Phallus broad with curved, slender ventral termination with an apical spine, with leaf-like deciduous cornuti, cornuti sockets are visible.

Female. Unknown.

Distribution. India (Karnataka); Vietnam ( Pathania et al., 2020).

Remarks. Diplocalyptis ferruginimixta looks similar to D. tennuicula Razowski from Zhejiang, China but can be distinguished by the broad uncus, the dorsal process of the labis, and the long, curved terminal process of the phallus ( Razowski, 2009). This species is newly recorded in India.
