Description. Head. Clothed brownish cream ochreous scales. Ocellus well developed. Vertex and dorsal part of frons clothed with anterior and forward projected cream brownish scales, base of the frons with small appressed upwardly projected light brownish coloured scales. Labial palpi brownish; first segment brownish ochreous scale; 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 dark brown interspersed with dark gray scales; middle legs with a pair of tibial spurs; hind tibia covered with dense, brownish grey scales in male, inner margin with a tuft of long, brownish orange coloured long hair pencil, originating from base of hindtibia. Wings: Forewing (wingspan 14–16 mm; n=8) subrectangular, pale brownish grey ground color with deep dark brownish band medially and subapically, tinged with dark greyish scales; costal fold broad, clothed with brownish ochreous scales; 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; socii small; 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, lateral lobes of vinculum rather long, pointed. Phallus broad with curved, slender ventral termination with apical spine, with bunch of deciduous cornuti.
Female. Unknown.

Distribution. India (Karnataka), Sri Lanka (Maskeliya) (Meyrick, 1908).
Remarks. In the present study, D. ferruginimixta Razowski, 2009 and D. operosa (Meyrick, 1908) are new additions to the Indian Diplocalyptis fauna. D. operosa is similar to D. ferruginimixta Razowski but the uncus is longer in D. ferruginimixta. Eight species of Diplocalyptis species are currently known worldwide (Gilligan et al., 2018), with only one species (Diplocalyptis congruentana (Kennel, 1901)) previously recorded from India (Pathania et al., 2020). This study increases the number of Indian Diplocalyptis species to three.
