( Figures 2, 7 , 12 , 17 )

1922. Lumaria exalbescens Meyrick , ( Capua ), Zool. Meded. 7: 81.

Type Locality: India, Palni Hills, Travancore, Coorg ( probolias ); Indonesia, Java, Tegal ( exalbescens ) ( Pathania et al., 2020).

Material examined: INDIA: Himachal Pradesh: Berthin (31.4188° N, 76.6427° E, 300m), 1♂ and 1♀, 21.ix.2018, Light trap coll. Santhosh.

Description: Ocellus well developed. Vertex and apex of the frons with anteriorly projected light yellow scales. Rest of frontal region covered with small appressed, upwardly projected, pale yellow scales. Labial palpi small, covered with loose pale yellow scales; second segment bigger than rest of two, terminal segment small. Antenna thread like filiform, clothed with light yellowish brown scales.

Thorax: Covered with pale brown scales, three pairs of legs clothed with pale brown scales

Wings: Wing span 9 mm. Forewing not expanding posteriorly, fairly broad, costa weakly convex, termen rather straight, weakly oblique; costal fold absent. Ground color creamy suffused pale ochreous fromanal regionto termen, strigulated and dotted brown especially along dorsum, black-brown spot at end of median cell. Dorsobasal blotch elongate, brown; median fascia ochreous brownish; subapical blotch brownish. Cilia concolorous with ground color. Subcosta reached to the median of costal margin. R1 arises from 1/3 discal cell. R1, R2 and R3 parallel to each other. R4 and R5 stalked. R5 and M1 parallel to each other. M2 and M3 connate basally. CuA1 arises from the apex of discal cell. CuA2 arises from ¾ discal cell. CuP absent. 1A+ 2A present. 3A absent. Hindwing pale brownish grey, paler basally; cilia whitegrey.Hindwing Rs and M1 are stalked and CuP present.

Abdomen: Clothed with pale yellow and brown scales.

Male genitalia: Uncus expanded and slender in distal half, broad apex. Gnathos rather long, valva tapered terminally; costal margin highly convex. Socii reduced. Sacculus slender with several thorns in distal half and group of long hairs ventromedially.Aedeagus slender, curved, with long dorsal slit, cornuti absent.

Distribution: India (Himachal Pradesh, Tamil Nadu, Karnataka). Elsewhere: Indonesia (Java), Sri Lanka and Vietnam ( Pathania et al., 2020)

Remarks: Lumaria probolias is closely similar to Lumaria petrophora (Meyrick, 1938) but is distinct by dark yellowish brown while L. petrophora is pale yellowish. Broader, subtriangular forewing with narrow median dark band in L. probolias compared to broad band in L. petrophora . The costal spot on L. Probolias of forewing is smaller than that of L. petrophora . In male genitalia of L. probolias , apex of tegumen strongly curved and highly sclerotized with narrow gnathos. Sacculus is medium, slender throughout the length with highly sclerotized bristles and aedeagus is weakly curved in L. probolias compared to L. petrophora . Razowski and his co-workers (2010) studied and discussed different Lumaria species.
