Subgenus Jorama Otte, 1988

Otte, 1988: 316; Gorochov, 1996: 40; Ma et al., 2015: 445; Gorochov, 2016: 26 Remarks. This subgenus is characterised by the head moderately depressed dorsoventrally; male anal plate with widely rounded or widely truncate apex and without strong setae directed upwards at apex or on dorsum along median part of its posterior edge; the male genitalia with posterolateral epiphallic lobes not widened and having numerous small denticles or tubercles ( Gorochov, 2016). Eight species are known from the Philippines, New Guinea, Taiwan and Lesser Sunda Islands ( Cigliano et al., 2020). These species are typically differentiated by the shape of male metanotal gland and male genitalia (particularly the shape of posterolateral epiphallic lobes and ectoparameres). Three species are known in the Philippines ( Cigliano et al., 2020): Duolandrevus (Jorama) curtipennis Chopard, 1937 of Palawan and Mindoro; Duolandrevus (Jorama) isagorensis ( Otte, 1988) of Camarines Sur; and Duolandrevus (Jorama) palawanensis ( Otte, 1988) of Palawan.
