Pinkaew leg.; np8493 (♂, genitalia slide NP3078); KKIC .

Diagnosis. The forewing of Loboschiza martia is distinguished by a rather straight costal margin and a distinct transverse sinuate band medially. The male genitalia of L. martia are most similar to those of L. lunata ( Anan & Pinkaew, 2016) , sharing a crescent shape cucullus but the ventral process of the cucullus has a single spine at the apex in L. lunata that is absent in L. martia . These two species also differ in the shape of the tegumen (ovate in L. martia but subtriangular in L. lunata ) and phallus (cylindrical in L. martia but flask-shaped in L. lunata ).

Redescription. Head ( Fig. 7 ): Lower frons orange white, upper frons and vertex orange; labial palpus porrect, first segment orange white, second segment dilated apically, slightly darker, from light orange at base to orange at apex, apical 1/2 sparsely mixed with brownish grey small spots, third segment orange. Antenna brown, basal segments covered with orange scales.

Thorax: Pronotal collar orange; tegulae orange red, interior 1/3 with longitudinal greyish band, apical 1/3 light orange; mesonotum orange mixed with grey, posterior crest indistinct; hindlegs without modified scales. Forewing subrectangular, wingspan 8.1–8.5 mm in male (n = 3) ( Fig. 2 ), costal margin rather straight, except at wing base and apex; termen rather straight and oblique; costal strigulae well developed especially in basal 1/2, yellowish orange separated by blackish streaks; wing pattern two-toned, basal 2/3 with greyish brown ground color, with various shape of well-defined oblique orange red bands, a distinct transverse band beyond middle of wing, interrupted medially, apical 1/3 of wing with transverse, irregular, sinuous orange striae on blackish ground, inner margin edged with a sinuate silvery band, fringe scales blackish; underside light greyish brown with white spots along costa and termen between R 5 and M 1 and between M 1 and M 2. Hindwing rather narrow, brown, slightly paler basally; underside light greyish brown.

Abdomen: Male genitalia ( Fig. 22 ) with tegumen subtriangular, moderately wide, with moderately dense scale sockets laterally; uncus absent; socii small, pendulous, membranous lobes, densely setose; gnathos composed of two lateral widened bands, moderately sclerotized basally, arising from near mid-length of tegumen; vinculum moderately wide laterally; juxta subtriangular; caulis rather long; anellus surrounding basal 1/2 of phallus; phallus long, wide, basal 1/2 wider, slightly sinuate, with dense cornuti sockets; valva subtriangular, with elongate basal opening, sacculus with a rather small subtriangular projecting lobe of dense, long and narrow spiniform setae ventromedially; neck indistinct; cucullus large, crescent-shaped, dorsal portion distinctly curve, slightly narrowed to apex, densely setose except on rounded apex, ventral process subtriangular pointing outward, rounded apex, densely setose.

Distribution. Australia and Thailand. New record to Thailand.

Remarks. Laspeyresia martia Meyrick, 1911 was transferred to Loboschiza martia ( Meyrick, 1911) by Horak (2006). Identification of adult specimens of L. martia ( Meyrick, 1911) from Thailand is based on comparison with original description by Meyrick (1911), and their genitalia are compared with genitalia illustrations (figs. 569–570) of L. martia that presented in Horak (2006).
