Disccusion. P. venustulum is recently moved to genus Svistella by Tan & Robillard (2012), but the male genitalia is more similar to P. nitidum , ( Fig. 2 CD). Brunner von Wattenwyl (1893) described Paratrigonidium vittatum stating “antennae white with first joint black, vertex brown, pronotum black, female forewing with black longitudinal band, leg black with joint reddish”. All these features are completely consistent with female P. venustulum ( Fig. 1D ). Thus this species is synonymized with P. venustulum as the junior synonym.
