Paratypes (2♂): Taiwan, Wushe ; 2 April 1983; Elevation: 1150m; Coll: Henry Townes; EMUS _CYN_ 0026 . Taiwan, Wushe ; 13 April 1983; Elevation: 1150m; Coll: Henry Townes; EMUS _CYN_0025 .

Diagnosis. See diagnosis for Diastrophus wushei .

Description. Female ( Fig. 9 View FIGURES 9–12 ). Holotype body length 3.3 mm.

Coloration. Antennae brown. Head brown. Mesosoma red brown, darker around mesoscutum. Metasoma red brown. Wings lightly obfuscated with slight infuscation around R1 and 2r. Legs amber brown.

Antenna ( Fig. 11 View FIGURES 9–12 ). 14—segmented. F1 equal to F2. Placodeal sensilla present on F2–F12.

Head ( Fig. 12 View FIGURES 9–12 ). In dorsal view 0.5× as long as wide; in anterior view 0.8× as tall as wide.

POL longer than OOL. Eye height to malar space ratio 1.5. Facial radiating striae weakly coarsely strigulate, not continuing to toruli. Supraclypeal area coriaceous with abundant setigenous punctures, also with apparent median carina. Clypeus subquadrate, broadly projected ventrally. Gena in frontal view curved, striate alutaceous. Vertex and upper face weakly coriaceous with abundant setigenous punctures. Upper occiput sculpture weakly coriaceous.

Mesosoma ( Figs. 13, 14, 15 View FIGURES 13–16 ). Pronotum rugose-coriaceous, with interspaces coriaceous and with abundant setigenous punctures, with dense short setae. Pronotal plate coriaceous with setigenous punctures, setae in two dorsolateral patches

Mesoscutum length and width subequal in dorsal view; smooth with large, deep setigenous punctures. Parapsidal grooves faint to indistinct. Anterior parallel lines faint to indistinct. Notauli complete, narrow anteriorly and slightly widened posteriorly.

Scutellum length and width subequal in dorsal view, broadly pointed apically, curving downward. Mesoscutellar disc strongly rugose with interspaces coriaceous; short setae scattered on dorsal area, especially concentrated on margins of disk, without depressed medial area.

Circumscutellar carina absent. Mesoscutellar foveae subtriangular, separated by a wide triangular carina anteriorly about as wide as either fovea; base glabrous. Dorsal axilla smooth with sparse setigenous punctures.

Metasoma. Shorter than combined length of head and mesosoma. Sparse short setae on T 2 in dorsal lateral patches, also sparse setae scattered on T3. Micropunctures present on T3 onwards.

Wings ( Fig. 16 View FIGURES 13–16 ). Marginal cell open, 3.8× as long as wide. Veins R1 and Rs not reaching margins. Rs straight to curved. Areolet present.

Male ( Fig 10 View FIGURES 9–12 ). Same as female except the following: Body length 2.6–2.8 mm (n = 2).

Antenna 15—segmented with placodeal sensilla present on F1–F13.

Biology. Unknown.
