Diagnosis. This species is somewhat similar to L . magnipalpis in the patterns of abdominal tergites ( Fig. 4 J), but can be distinguished from the latter by having the mesonotum yellow ( Fig. 3 A), and the pleura yellow, with brown patches above ( Fig. 3 B). Description. Male and female: Frons yellow to yellowish brown. Pedicel mostly yellowish brown; first flagellomere yellow. Palpus dark brown in male, black in female. Acrostichal setulae in ca. 14–16 irregular rows ( Fig. 3 A). Postpronotal lobe yellow ( Fig. 3 B). Scutellum brown along basal margin, brownish yellow medially, pale along distal margin ( Fig. 3 A). Halter white ( Fig. 3 B). Abdominal tergites yellow, with brown patches ( Fig. 4 J). Male terminalia: Epandrium with 3 setae near posterior margin and 5 setae on ventral corner per side ( Fig. 8 A). Paramere with ca. 5 sensilla subapically ( Fig. 8 B). Aedeagus slender basally, with pubescence on distal 1/3 ( Fig. 8 B). FIGURE 7. Leucophenga magnipalpis Duda, 1924 , male: A.
