CONCLUSION

The Oriental fauna of Aulacidae appears to be poorly investigated although very rich in species ( Turrisi 2017). As highlighted by Turrisi (2013) and Smith (2017), Aulacus is poor in species in the Oriental Region and very rarely collected. The recent investigations, containing descriptions of many new species (see introduction) show a consistent number coming especially from Laos, Vietnam, and Laos. A significant contribution to improve the aulacid material from poorly investigated and rich-species areas has been done by Oberosterreichisches Museum, Linz ( Austria), and by the Thai Inventory, the former especially in Laos (Turrisi, unpub.), the latter in Thailand. With regard to Thailand, the aulacid fauna currently includes only eight species, most of them being only recently described ( Smith 2001, Turrisi and Smith 2011, Turrisi and Watanabe 2011, Turrisi and Nobile 2016). Visitpanich (1994) recorded an undetermined Pristaulacus species reared from Coffee stems together with the host Xylotrechus quadripes Chevrolat ( Coleoptera , Cerambycidae ). According to the data from literature and the new species and records in this paper, the aulacid fauna of Thailand includes 14 species, and an additional undetermined Pristaulacus ( Table 1 ).
