= Aurelianus Błeszyński, 1962 d: 2 . Type species: Chilo discellus Walker, 1863

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).
