Type species: Micraglossa scoparialis Warren, 1891 .

DIAGNOSIS

Descriptions of Micraglossa are provided in Nuss (1999) and Li et al. (2010). Micraglossa exhibits a typical scopariine pattern with the X-shaped postmedian and subterminal lines but can be separated from other related genera by the shiny golden-colored forewing markings. The absence of appendix bursae in female genitalia separates it from Eudonia and Scoparia ( Léger et al., 2019) . Male genitalia exhibit the following characters: uncus elongate, relatively narrow; gnathos usually slightly longer than uncus, with small apical tooth pointing downwards; valva with spine projection on innerside in some species, distal half of valva usually bent upwards; vesica with or without cornuti. Female genitalia exhibit the following characters: posterior and anterior apophyses shorter than in Eudonia ; colliculum long, tubular, lightly sclerotized; ductus bursae long, membranous, sometimes with loops; corpus bursae globular, membranous, without appendix bursae, with ovate or streak-like signum (W. Li et al., 2010).

DISTRIBUTION

Oriental and Australasian regions. The distribution stretches from temperate China and Japan southwards to Australia ( Nuss et al., 2003 –2023). Three species are found in the Philippines: Micraglossa tagalica Nuss, 1998 , M. polisensis sp. n., M. kianganensis sp. n.

PHYLOGENETIC RELATIONSHIPS

Micraglossa is sister to the clade formed by Eudonia and Scoparia ( Léger et al., 2019) .
