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).
