03C2B63C4A06FFB7FF6C6E0FFE59AF6C.taxon	etymology	Etymology. Derived from Greek ξενικός, strange, referring to the unusual male cerci, very different compared to species of other subgenera of Conocephalus, the diminutive alluding to the small body size. Gender is masculine.	en	Rubio, Lucas, Braun, Holger (2024): A new species of Conocephalus (Orthoptera: Tettigoniidae: Conocephalinae) from Argentina with extraordinarily broad-band ultrasound calling song.

03C2B63C4A06FFB7FF6C6E0FFE59AF6C.taxon	diagnosis	Diagnosis. Smaller than most South American Conocephalus species. The strongly reduced wings leave the entire abdomen exposed. Fastigium very narrow, prosternum with a pair of delicate spines, and tip of hind tibia without internal dorsal spine. Male cerci slender, with a very long internal transversal spine at the tip, male subgenital plate simple with short styli. Ovipositor long and straight.	en	Rubio, Lucas, Braun, Holger (2024): A new species of Conocephalus (Orthoptera: Tettigoniidae: Conocephalinae) from Argentina with extraordinarily broad-band ultrasound calling song.

03C2B63C4A06FFB5FF6C6900FD19AA8B.taxon	etymology	Etymology. Tuyú is of Guaraní origin, meaning mud or marshland, and is the name of the region in the very east of Buenos Aires Province where the species was found.

03C2B63C4A06FFB5FF6C6900FD19AA8B.taxon	diagnosis	Diagnosis. Very small. Mostly green, with reddish brown dorsal band along entire body from fastigium to penultimate abdominal tergite, on head and pronotum with thin white fringes, which turn slightly broader and yellowish on the abdomen, especially in males (Fig. 1, 2 A, B). Fastigium distinctly narrower than pedicellus, in diameter hardly exceeding the first flagellomere (Fig. 2 C). Tegmina in males slightly longer than pronotum, in females shorter than pronotum. All femora without ventral spines. In males fore femora more robust than middle femora and the delicate ventral spines of the fore tibiae blackish, close-fitting to the tibia and forming a line on each ventral edge. In males last tergite in the middle with a pair of small elongate lobules enclosing a narrow gap. Male cerci with moderately slender basal part with obtuse tip, just in front of this tip with a very long and acute internal spine, forming an angle of about 70 degrees to the base and reaching base of opposite cercus (Fig. 2 E, F, Fig. 3 B). Female ovipositor straight, about as long as abdomen or three-fours the length of the hind tibia (Fig. 1 C).	en	Rubio, Lucas, Braun, Holger (2024): A new species of Conocephalus (Orthoptera: Tettigoniidae: Conocephalinae) from Argentina with extraordinarily broad-band ultrasound calling song.

03C2B63C4A06FFB5FF6C6900FD19AA8B.taxon	biology_ecology	Habitat and phenology. Individuals were found in meadows and grassland in or close to sand dunes alongside the beaches of the Atlantic coast, both well preserved or modified by the introduction of exotic trees such as conifers and eucalyptus. There are also observations from Córdoba, near banks of Río Santa Rosa, indicating that it could be a species of coastal and riparian habitats. We found adults from January to March, whereas one of the Córdoba records is from May. The insects appear to be more active during night, leaving the safety of grassland to feed on the inflorescences of native herbaceous plants such as Oenothera mollissima and Solidago chilensis.	en	Rubio, Lucas, Braun, Holger (2024): A new species of Conocephalus (Orthoptera: Tettigoniidae: Conocephalinae) from Argentina with extraordinarily broad-band ultrasound calling song.

03C2B63C4A06FFB5FF6C6900FD19AA8B.taxon	description	Calling song. The male from Aguas Verdes (21. II. 2023) produced from 26. II. to 14. III. at night a continuous song with the uniform syllable trains sometimes lasting several minutes. At 26.5 ° C he made 13.4 syllables per second, although in the natural habitat with lower night temperatures the males certainly call more slowly. No calling activity could be detected during daylight. The short and very soft signal at the beginning of each syllable probably corresponds to the opening stroke of the tegmina (not present at the very end of recorded trains), followed by short crescendos of directly decaying impulses of the closing stroke, most probably corresponding to individual tooth scraper impacts (Fig. 4 A, B). The carrier frequency spectrum is entirely in the ultrasound and exceedingly broad, from around 25 kHz to 90 kHz (Fig. 4 C).	en	Rubio, Lucas, Braun, Holger (2024): A new species of Conocephalus (Orthoptera: Tettigoniidae: Conocephalinae) from Argentina with extraordinarily broad-band ultrasound calling song.
