Pseudoleptonema tansoongnerni Laudee & Malicky, 2017

( Fig. 257 )

Pseudoleptonema tansoongnerni Laudee & Malicky, 2017: 384 [ Holotype male; Laos; PSUNHM].

Remarks. According to the figures in the original description ( Laudee & Malicky, 2017), the genitalia are quite similar to those of P. quinquefasciatum . The wing pattern of P. tansoongerni can be distinguished from that of P. quiquefasciatum by having a large transparent region subapically ( Laudee & Malicky, 2017) ( Fig. 257 ).
