Siphona (Aphantorhaphopsis) kanmiyai sp. nov.

( Figs 16–19 , 89 )

Type material. HOLOTYPE: J ( BLKU), TAIWAN / Huanshan / Chichiawanchi / Taichung Hsien / 6 Nov. 1985 / K. Kanmiya . PARATYPES: TAIWAN: 4 JJ ( KUM), same data as holotype; 1 J ( KUM),Mt.Lishan, Taiwan, 1.vi.1971, K. Kanmiya.

Diagnosis. Fronto-orbital plate with yellowish pruinosity, bearing a row of short setae on lower part; 3 postsutural dorsocentral setae; abdominal tergites 4–5 entirely blackish, with whitish gray pruinosity on anterior part.

This species is very similar to S. (A.) coactilis sp. nov. and S. (A.) matsumotoi sp. nov., but is easily distinguished from them in having nearly straight surstylus of the male postabdomen in lateral view.

Very similar to S. (A.) matsumotoi sp. nov., but differing from it as follows:

Description. Body length 3.5–4.0 mm. Male. Head. Antenna with postpedicel blackish; arista brown. Vertex approximately 0.37 of head width; parafacial subequal in width to width of 2nd aristomere at middle height; fronto-orbital plate with row of short setae on lower part; prementum 3–4 times as long as wide and approximately 0.4 times as long as eye height; labella pad-like.

Thorax. Dorsum light gray in ground color, with whitish pruinosity; postpronotal lobe light yellow in ground color; apical half of scutellum yellowish; pleura brownish, with whitish gray pruinosity.

Abdomen. Syntergite 1+2 yellowish; tergite 3 yellowish, with whitish pruinosity on anterior margin; tergites 4–5 blackish entirely with whitish gray pruinosity on anterior 2/3.

Male postabdomen. Surstylus nearly straight in apical half in lateral view, bearing long and strong inner setae; cerci weakly curved dorsally in middle in lateral view, apex slightly curved ventrally; pregonite somewhat rounded apically, without seta; postgonite rounded apically; epiphallus absent; distiphallus mostly sclerotized in lateral view with some spinules at base ventrally.

Female. Differing from male as follows: postpedicel slender, approximately 3.5 times as long as wide.

Etymology. This species is named in honor of Dr. K. Kanmiya (Kurume City, Japan), who collected the holotype.

Host. Unknown.

Distribution. Taiwan.
