03DE87F0FFBC7D09EAECFDA30EA4FDFD.taxon	etymology	Etymology. This is named after the family name of the host species, Tetrigidae, plus the Greek suffix, myia, meaning fly.	en	Shima, Hiroshi, Takahashi, Hajime (2011): Tetrigimyia minor, a new genus and species of Tachinidae (Diptera) parasitic on Formosatettix larvatus (Orthoptera: Tetrigidae) in Japan.

03DE87F0FFBC7D09EAECFDA30EA4FDFD.taxon	discussion	Remarks. Tetrigimyia is similar in general appearance to the Central and South American genus Calodexia Townsend. It differs from Calodexia in possessing a wide frons in both sexes, wing veins R 4 + 5 and M ending at wing apex, fore tibia with 2 posterior setae, female 5 th abdominal tergite conical and terminalia curved ventrally, instead of rounded apically with the terminalia directed forward as in Calodexia. The new species of Tetrigimyia lays unincubated eggs with a hard chorion on the host exoskeleton. In this respect it is also different from ovolarviparous Calodexia species. First postsutural supra-alar seta is slightly longer than 1 st postsutural intra-alar seta in the type species. This appears to conflict with one of the main blondeliine character states, but it may be due to the unusually fine and short 1 st postsutural intra-alar seta in this species. The first postsutural supra-alar seta is smaller than the notopleural seta and other characteristics, such as long and divergent subapical scutellar setae, wing vein M rounded and obtuse at the bend, and wing veins R 4 + 5 and M ending near wing apex, correspond well to the criteria of the Blondeliini (Wood 1985). In the key to genera of the Palaearctic Tachinidae (Tschorsnig & Richter 1998), this genus keys to Paracraspedothrix. However, the female of Paracraspedothrix has a short, globose abdomen, lacking a telescopic ovipositor, and lays embryonated eggs with transparent chorion, while the male is peculiar in having a large antenna and an arista thickened on its basal 2 / 3. Paracraspedothrix is also different from Tetrigimyia in the wide gena and wing with crossvein dm-cu attached to vein M closer to crossvein r-m than to bend of vein M. In both genera veins R 4 + 5 and M end at or near the wing apex, but in Paracraspedothrix these veins end much far apart.	en	Shima, Hiroshi, Takahashi, Hajime (2011): Tetrigimyia minor, a new genus and species of Tachinidae (Diptera) parasitic on Formosatettix larvatus (Orthoptera: Tetrigidae) in Japan.

03DE87F0FFBE7D0DEAECFF710F88F962.taxon	biology_ecology	Biology. Formosatettix larvatus is apterous and its adults and larvae are found in dark undergrowth of elm woods eating dead and decaying leaves. Tetrigimyia minor is oviparous; females lay planoconvex elliptical eggs (0.5 mm long, 0.25 mm wide) on the ventrolateral portion of host abdomen. Parasitized adults or larvae were found in April (Akagawa, Oita Pref.), May (Karasawa River, Hanno City and Mt. Daisen, Tottori Pref.), and June and October (Akagawa). This tachinid appears to have at least two generations a year, adults appearing in late spring and again in summer. It is possible that the tachinid overwinters as a 2 nd or 3 rd instar in the host’s body. Percentages of parasitism of this fly were high at Akagawa, but rather low at Karasawa and Mt. Daisen (Table 1). The first instar tachinid larva emerges through the operculum of the egg within a week after oviposition and penetrates into the host haemocoel through the abdominal intersegmental membrane, moving at least 1.6 mm apart from the egg. Second and third instars form a respiratory funnel attached to a host abdominal spiracle. Dissection of dead hosts revealed that there were more than one (up to five) tachinid larvae per host. Usually only one mature larva emerged from a host and pupated, but in some cases two successfully emerged and eclosed.
