Rhipidia (Rhipidia) septentrionis Alexander, 1913

( Fig. 68 )

Rhipidia pulchra septentrionis Alexander, 1913: 206 . Type locality: Tokyo ( Japan).

Diagnosis. Male antenna not pectinate ( Alexander 1920). Wing pale grey with numerous small and faint grey spots and some dark spots; Sc1 ending just distad of midlength of Rs, basal section of CuA1 proximad of fork of M. Lobe of gonostylus with three rostral spines ( Alexander 1966).

Description. Male. Wing length 7.5 mm.

Wing (fig. 68) pale grey; all cells with numerous small and faint grey spots; some dark spots at origin of Rs, fork of Rs, fork of R1 and sub-tip of A2, no larger spot on costal region; veins pale yellow, darker in clouded areas. Venation: Sc1 ending just distad of midlength of Rs, Sc2 near its tip; basal section of CuA1 proximad of fork of M.

Female. Unknown.

Specimens examined. Holotype male (USNM), Japan: Tokyo, 1912. IV. 25, S. I. Kuwana and assistants. One wing is mounted on a similarly labeled microscope slide. The rest of the specimen was not found.

Distribution. China (East, Jiangxi); Russia, Japan.

Remarks. For description and illustration of this species, also see Alexander (1920, 1966). This species is similar to R. (R.) pulchra de Meijere, 1904 from Indonesia, but it can be easily distinguished from the latter by the unusually long rostral spines near midlength of rostral prolongation ( Alexander 1966). In R. (R.) pulchra , the rostral spines are shorter and placed near the tip of rostral prolongation (de Meijere 1911; Alexander 1966).
