DIAGNOSIS

Calamotropha was revised by Błeszyński (1961) and the genus was redescribed by Landry (1995). The combination of forewing Rs4 vein stalked with Rs2+Rs3 and the open hindwing cell characterize the genus ( Landry, 1995; Léger et al., 2019). Forewing white or brown, generally with a median and a subterminal fascia, margin with several small dots (W. Li & Li, 2012a; pers. obs.). Male genitalia with hairs at base of uncus; tegumen usually with short dorsal roof; valva relatively short; pseudosaccus present; vinculum subtriangular, conspicuously protruding anterad, saccus blunt ( Landry, 1995; W. Li & Li, 2012a). Female genitalia with papillae anales coalesced dorsally and ventrally; posterior apophyses roughly as long as tergite VIII; anterior apophyses short or absent; antrum often sclerotized; ductus bursae usually slender; corpus bursae usually without signum.

DISTRIBUTION

Known from the Afrotropical, the Palearctic, Oriental, and Australasian regions ( Błeszyński, 1961). Seven species are reported here from the Philippines, of which five can be confidently named: Calamotropha anacantha sp. n., Calamotropha atkinsoni Zeller, 1863 , Calamotropha obliterans (Walker, 1863) , Calamotropha philippinensis sp. n., Calamotropha unicolorellus (Zeller, 1863) .

PHYLOGENETIC RELATIONSHIPS

Calamotropha is part of the Calamotrophini, also including Pseudocatharylla Błeszyński, 1961 and Vaxi Błeszyński, 1962 ( Léger et al., 2019).
