 Records from literature. Enderlein (1912, 1913), Konishi (1990, 1991).   
 Type locality. “ Formosa: Hoozan ” (Enderlein 1912).   
 Notes on type material. According to Enderlein (1912: 265) the type material consists of 8 females stored in ZMHB and in DEI. In the latter Museum I found only three specimens surely belonging to the type series, and 20 additional specimens (10 females and 10 males, see material) collected by H. Sauter in Taiwan. No type specimen was found in ZMHB. According to Huflejt (1996), other four type specimens (not examined) are stored in the collection of Museum and Institute of Zoology of the Polish Academy of Sciences in Warsaw. For this taxon Enderlein (1912) did not indicate an holotype, thus, the examined three type specimens are here considered as syntypes. Megjaszai T. in the year 1999 (original handwritten labels) designated, among these syntypes, one lectotype and two paralectotypes (unpublished), which I here formally establish (ICZN 1999: article 74). The lectotype lacks most of the antennae (except A1–A5 of left antenna and A1–A6 of right antenna), tarsi of right mid leg, and of left hind leg, and valvulae 3 of ovipositor. With regard to these lacking parts of the body, a description is provided on the basis of the other examined specimens (in brackets).

 Distribution. China (*), Japan (Iriomote-jima Island, Okinawa-hontô Island), Taiwan.   
 Remarks. Pristaulacus comptipennis is recorded from China for the first time. It is easily identified, together with two other eastern Palaearctic species, by the presence of a deep median occipital groove and the entirely blackish metasoma, without red marks; the differences among those species are given in the key to species.   
 Biology. Host: Ceresium elongatum Matsushita, 1933 (Coleoptera, Cerambycidae) (Konishi 1991).
