Isophya sonora sp. n.
Holotype: Male - Turkey: Trabzon, Çaykara, Uzungöl-Demirkapı road, 07.08.2020, 40°34’20.453″ N, 40°23’19.289″ E, 1611m (coll. H. Sevgili & O. Sevgili). GoogleMaps
Examined materials: The same locality with holotype ( Fig 1 View FIGURE 1 ). 2 males, (coll. H. Sevgili & O. Sevgili). All materials are preserved in ethanol .
Description: Male. Fastigium verticis slightly narrower than scapus, distinctly narrowing distally, slightly depressed and sulcate dorsally ( Fig. 2A View FIGURE 2 ).
Lateral keels of pronotum distinct, almost parallel in prozona and very strongly diverging backwards on metazona up to caudal margin ( Fig. 2B View FIGURE 2 ); frontal and caudal margin of the disk almost straight ( Fig. 2B View FIGURE 2 ). Pronotum with concave margin in profile and distinctly elevated at metazona ( Fig. 2C View FIGURE 2 ); paranota with frontal margin oblique, caudal margin long and oblique ( Fig. 2C View FIGURE 2 ).
Tegmina elongate, about more than 1.5 times the length of pronotum ( Fig 2D View FIGURE 2 ); tegminal “disc” longer than wide, right margin of disc not projecting; speculum distinctly large, costal area of tegmen broadened ( Fig. 2B View FIGURE 2 , 3 View FIGURE 3 A–B, D).
Stridulatory file about 2.82 mm, with about 66 teeth, each gradually widening and becoming progressively sparse towards the apex ( Fig. 4 View FIGURE 4 , 5 View FIGURE 5 A–D). The shape and width of the teeth in the distal and proximal part of the file are distinctly different from each other ( Fig. 5 View FIGURE 5 C–F). The distance between tegmina edge and apex of the file is 0.60 mm.
Fore femora 1.53 and hind femora 3.78 times as long as pronotum and without spines on ventral margins.
Epiproct wide and long ( Fig. 3C View FIGURE 3 ), extending to the middle of the cerci; cerci moderately long, proximal 3/4 narrowing distally; distal ¼–⅕ incurved into and wide angle, slightly narrowed subapically, with narrowly rounded apex and with a distinct denticle ( Fig. 2 View FIGURE 2 D–E). Subgenital plate large at base, tapering posteriorly, with a deep rounded or “V” shape incision ( Fig. 2F View FIGURE 2 ).
Coloration as in Figures 3 View FIGURE 3 A–D.
Female: Unknown.
Etymology: “ sonora ” is a Latin word, it means loud and noisy. The new species has loud male calling song.
Measurements (Average, Standard Deviation, mm, n= 3 males): Body length: 26.12 (0.51), Pronotum: 4.31 (0.29), Tegmina: 6.65 (0.09), Fore femur: 6.6 (0.41), Hind femur: 16. 30 (0.49).
Calling Song. The songs were recorded in the evening, while the air temperature was 27°C. The calling song is very loud and consists of a series of irregular syllables repeated at the approximate rate of 0. 362 s ( Fig. 6A View FIGURE 6 ). The syllables consist of 5–6 spaced crescendo impulses and nearly 34 densely formed decrescendo impulses ( Fig. 6 View FIGURE 6 C–D). There are also some songs that produce 1–3 impulses right after the main syllables ( Fig. 6D View FIGURE 6 ). The major part of each syllable lasts about 0.162 s. The carrier wave of the song has its intensive signals between 15–25 kHz, but the frequency components with detectable sound pressure spread over the frequency range of 5kHz–45kHz ( Fig. 7 View FIGURE 7 ). Some other measurements of the male calling song are shown in Table 1 View TABLE 1 .
