Genus Pseudoleptonema Mosely, 1933 View in CoL

Pseudoleptonema Mosely, 1933: 8 View in CoL [Type species: Macronema ceylanicum Hagen, 1858 , by original designation].

Diagnosis. This genus can be distinguished from other Macronematinae genera by forewing Rs base entire. Head with five setal warts; two anterior, two posterior and one anteromesal setal wart ( Fig. 256 View Figs ). Wing pattern dark brown in alcohol with white patterns varying in every species.

Remarks. Mosely (1933) established the genus Pseudoleptonema based on the type species Leptonema ceylanicum Hagen, 1858 . It was originally described as Macronema ceylanicum Hagen, 1858 but Ulmer transferred it in Leptonema (1907) . Mosely (1933) established the genus Pseudoleptonema based on the type species Leptonema ceylanicum Hagen, 1858 because the generic characters of L. ceylanicum such as number of spurs, venation, genitalia, and maxillary palps do not fit those of the genus Leptonema . Mosely (1933) initially characterised the genus Pseudoleptonema as possessing 1.4.4 spurs, maxillary palpi with second segments slightly longer than the third, forewings with upper R branch running into the first apical sector, and forked Sc. However, P. quinquefasciatum Martynov, 1935 has 0.4.4 tibial spurs, and the forewing Sc of P. supalak Malicky & Chantaramongkol, 1998 is not forked.
