Tachi, Takuji & Shima, Hiroshi, 2023, Systematic study of the subgenus Aphantorhaphopsis of the genus Siphona in East Asia and the Oriental Region (Diptera: Tachinidae), Acta Entomologica Musei Nationalis Pragae (Acta. Ent. Mus. Natl. Pragae) 63 (1), pp. 213-247 : 228

Siphona siphonoides group

Diagnosis. Male postabdomen: pregonite with one weak seta on dorsal portion ( Figs 42 , 46 , 51 , 56 , 60 , 65 ); epiphallus absent or present; distiphallus subrectangular in lateral view.

Remarks. Monophyly of this group is provided by one short seta on the dorsal part of the male pregonite. The seta of the S. siphonoides group is distinctly different from that of Ceranthia which is strong and long. According to ANDERSEN (1996), among the European Aphantorhaphopsis species, S. (A.) brunnescens (Villeneuve) , S. (A.) siphonoides (Strobl) , S. (A.) starkei (Mesnil) and S. (A.) verralli (Wainwright) have the seta on the pregonite. The following East Asian and Oriental species are included in this group: S. (A.) alticola (Mesnil) , S. (A.) crassulata (Mesnil) , S. (A.) curta sp. nov., S. (A.) laticornis (Malloch) , and S. (A.) orientalis (Townsend) .
