Pristaulacus comptipennis Enderlein 1912

( Figs 19–27 )

Pristaulacus comptipennis Enderlein 1912: 265 ; 1913: 319, 326; Hedicke 1939: 7; Konishi 1990: 652; 1991: 564; Smith 2001: 282; Turrisi 2007: 28; Turrisi et al. 2009: 56.

Type material. According to Enderlein (1912), the type material includes eight females. Turrisi (2007) designated a lectotype and two paralectotypes ( SDEI, examined).

Material examined. See Turrisi (2007). Additional specimens: Japan, Kagoshima Prefecture, Amami-ôshima, Mount Yui-dake, 2.VII.2004, 2♀, Hiroshi Makihara leg. (Malaise trap) ( TUAE); same data, 27.VII.2004, 1♀ ( TUAE); Japan, Okinawa-hontô, Oku, Kunigami-son, 10.VII.2003, 1♀, H. Makihara leg. (at light) ( DBAC); Japan, Kohama-jima (Yaeyama Islands, Ryukyus), 24°20'N, 123°58'E, 1♂ ex larva, emerged 7.VII.2007, from Ficus superba var. japonica Miq. collected 21.II.2007, together with Olenecamptus bilobus nipponensis Dillon & Dillon ; Taiwan, Hoozan, 7.IX.1910, 1♀, H. Sauter leg. (labelled as “Cotypus”) ( NHRS); Taiwan, Keelung, 1910, 1♂, Victor Kühne leg. ( USNM); Laos, Bolikhamsai Province, Ban Nape environs, 350 m a.s.l., 18°20'N, 105°08'E, 1♀, Jendek & Sausa leg. ( OLML); China: Hong Kong, Tai Po Kau Forest, 50Q KK 094 813, 370 m, 21.VI.2006, 1♀, C. Barthélémy leg. ( DBAC).

Description. See Enderlein (1912). Redescriptions and data on intraspecific variation are provided by Konishi (1990, 1991) and Turrisi (2007).

Distribution. Japan (Amami-ôshima, Okinawa-hontô, Iriomote-jima, Kohama-jima); China ( Hong Kong), Taiwan, Laos ( Enderlein 1912, 1913; Konishi 1990, 1991; Turrisi 2007) ( Fig. 186 ).

Remarks. This species is newly recorded for Laos, extending its range considerably westward. It is also newly recorded for Amami-ôshima and Kohama-jima ( Fig. 186 ). The three females collected on Amami-ôshima differ from the specimens from Taiwan in having very reduced wing markings, with only one moderately wide brown spot below stigma. A similar colour variation was reported by Konishi (1991), who recorded reduced and paler wing markings in specimens from Okinawa-hontô Island compared with specimens from Iriomote-jima and Taiwan. He concluded that a reduction of wing markings occurs from south ( Taiwan and Iriomote-jima) to north (Okinawa-hontô). Our observations seem to confirm such clinal variation, with the northernmost specimens from Amami-ôshima Island having the extreme reduction of wing markings.

Biology. The probable host is Ceresium elongatum Matsushita ( Coleoptera , Cerambycidae ), which emerged from dead wood of an unidentified tree species ( Konishi 1991). Based on the specimen from Kohama-jima, we add a possible new host, Olenecamptus bilobus nipponensis Dillon & Dillon ( Coleoptera : Cerambycidae ), obtained from wood of Ficus superba var. japonica Miq. (Moraceae) .
