Description. Male (Holotype). General coloration gray and brown with black and white spots. Fastigium with a small depression. Pronotum in dorsal view slightly longer than wide, with lateral carinae compressed and convergent in the metazona; the posterior margin emarginated with the incision slightly pointed ( Fig 2 ); the ventral border in lateral view with one emargination in the middle. Prozona as long as metazona. Tegmen reaching the margin of the first tergite of abdomen; tenth (10th) tergite in middle semicircular, excised. Cerci approximately twice as long as wide, slender and conical pointed apically; inner tooth placed in the apical third. Cerci straight between the apex and the inner tooth ( Fig. 5 ). Epiproct elongate and narrow rounded at the apex. Titillators in dorsal view with apical branch shorter than basal branch; basal branch elongate, four times longer than the width, the apical branch robust, narrow in all its length and pointed at the apex ( Fig 8 ). Subgenital plate almost square with the posterior margin slightly emarginated.

Femal e ( Fig 12 ). Cerci short, broad-conical. Seventh (7 th) sclerite with a median protuberance situated near the anterior margin. This protuberance is not rounded in lateral view, with the anterior margin truncate. Subgenital plate almost trapezoidal carinate in the middle with two thickenings in the apical part ( Fig. 11 ) separated transversely. Ovipositor elongate almost straight, three times as long as pronotum.

Sonogram of male ( Fig 13 ). The male could be located while singing very close to the ground among the vegetation during the day. The song is composed by a long scheme lasting up to about 40 s and consisting of about 60 syllables repeated at the rate of about 1,5 s in which the sound is virtually continuous ( Fig 13 ), recorded on 17.V.2018, 20 oC. Oscillographic analysis shows that the hemisyllables last about 700 ms and the intervals between them about 60 ms.

Etymology. This species is named in loving memory of Xavier Ribes and David Iglesias, two Rural Agents died in 2017, for their love to Nature and commitment to protect it.

Measurements. See Table 1 .
