Siphona selecta (Pandelle, 1894)

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 : 220

Siphona selecta group

Diagnosis. Male postabdomen: surstylus with some long setae on inner side basally ( Figs 12 , 17 , 21 , 26 , 31 , 36 ); pregonite bare; epiphallus absent; distiphallus subrectangular or subtrapezoidal in lateral view.

Remarks. This group is considered monophyletic, which is supported by the presence of the inner basal setae on the surstylus. This condition is not found in other siphonines except for a few species of Actia ( A. darwini Shima, 1970 , A. destituta Tachi & Shima, 1998 and A. pokharana Shima, 1970 ). ANDERSEN (1996) redescribed two Europe- an species, S. (A.) samarensis and S. (A.) selecta , which have several inner setae on the basal portion of the male surstylus. Additionally, this character state is common to the following species: S. (A.) coactilis sp. nov., S. (A.) kanmiyai sp. nov., S. (A.) laboriosa , S. (A.) matsumotoi sp. nov., and S. (A.) selangor .
