Amphipsyche magna Banks, 1939

( Figs. 22–25 )

Amphipsyche magna Banks, 1939: 58 [Holotype male; Philippines; MCZ]; Barnard, 1984: 102 (description of female).

Diagnosis. Male. Forewing with no markings; median cell very obvious formed by M2–M3+4. Mesoscutellum with pair of dark circular markings ( Fig. 23 ).

Male genitalia. Inferior appendages slender and segmented; harpago blunt and shorter than coxopodite ( Fig. 22 ). Phallus apex with three pairs of endothecal spines ( Fig. 25 ), dorsal pair directed ventrally, mid and ventral pairs directed dorsally.

Distribution. Philippines (Luzon).

Remarks. The species has never been collected in our fieldwork in the Philippines therefore, no other individual was examined. However, Barnard (1984) provided a clear description of the species that was used as a reference for the diagnosis of this species. The genitalia ( Figs. 22, 24, 25 ) and thorax ( Fig. 23 ) were also redrawn from Barnard’s revision of the genus Amphipsyche (1984: Figs. 78–83 , 87 ).
