Diagnosis. Female. Body, including pronotal plate, sparsely haired; in front view, pronotal corner distinctly projecting; in lateral view, upper anterior margin with short, straight carina, and with pit just low end; scrobe smooth; its upper part with few scattered hairs (Fig. 3). Ovipositor sheath about 0.66 times as long as hind tibia, and about 7.7 times as long as width at midpoint (Fig. 5).
Male. Similar to female, but flagellomeres with long erect hairs; tyloids small, circular, found on segments 2–8.
Distribution. Palaearctic Region: Japan, new record (Kyushu and Ryukyus); Oriental Region: Taiwan.
Host. Unknown.

Remarks. According to Lin (1988), all paratypes should have been deposited in TARI. However, we found that some of the paratypes are stored at CNCI. Although the label data are incomplete, we have examined one male and one female paratypes. According to Lin (1988), Ph. chikoi has numerous grooves at the base of the syntergite: a median groove and five grooves on each sides of it. However, the number of these grooves sometimes vary in Japanese specimens. One of these grooves is incomplete or lacking in some specimens (Fig. 7). The type series was collected in the alpine zone at altitudes of 2150–2560 m, but the specimens treated intreated in this paper were collected in the plains (Kyushu University, Motooka, Nishi-ku, Fukuoka Prefecture, Japan) and in the low altitude zone at altitudes about 200–500 m from Japan. The Taiwanese samples werewere collected between April to December, while the Japanese ones were collected between December to April.
