Description of males (alive). General color green ( Figs. 32 , 33 ), postocular band delicate, whitish-creme extending onto sides of pronotum; antennae’s scape mostly green, pedicel whitish-creme, flagellum basal half light brown-orange, distal half greenish, with white annuli; fastigium of vertex (in dorsal view) broad, sub-conical, profusely sulcate, almost touching the sub-conical frontal fastigium which is distally more produced; occiput with a posterior sub-triangular blackish-gray mark. Pronotal disc ( Fig. 34 ) sub-pentagonal (in dorsal view), anterior margin light brown-orange with blackish-gray shadow underneath, posterior margin light-brown-orange with blackish-gray shadow above, both margins slightly emarginated; carina media green and moderately prominent; typical sulcus on pronotal disc conspicuous, green, shallow wide u shape, cutting the lateral carinae and extending to middle of lateral lobes; lateral lobes of pronotum ( Fig. 33 ) sub-rectangular (lateral view). Stridulatory area (Fig. 35) green with blackish-gray and light brown-orange edge, extending to the apex. Stridulatory file ( Fig. 36 ) with ca 76 teeth, 8 mm in length and 9 teeth/mm (8–12). Tegmina ( Figs. 32 , 33 ) ovate and elongated, surpassing the terminalia, almost completely overlapped, in some specimens tergites 8th– 10th may be slightly exposed when at rest; venation prominent, upper margin whitish with light brown-orange above; lower margin whitish-creme; hind wings vestigial. Terminal tergite ( Figs. 37a , 38 ) projected posteriorly into a stout process, divided by a deep sulcus, v-excised distally forming two broad distal angles. Cerci ( Figs. 37a , 38 , 39 ) made up of two processes, the main shaft is broader basally, then tapers gradually towards the acute apex, about 1/4 of the distal portion bends abruptly inwards; about mid length of the main shaft originates a secondary arm or process which bends inwards and tapers gradually towards the spike-like apex; epiproct ( Fig. 37 b) sub-circular, shallow truncated distally; internal genitalia as shown in Figs. 40 –41. Measurements (mm) males. Body length from vertex to end of abdomen: 18.9 ± 0.8 (18.0–20.0). Pronotum length: 3.3 ±0.2 (3.0–3.5). Tegmen length: 11.0 ± 1.5 (11.1–12.1). Fore femur length: 4.9 ± 0.2 (4.7–5.2). Mid femur length: 5.9 ± 0.5 (5.2–6.4). Hind femur length: 13.3 ± 1.1 (11.6–14.3). Description of females. Similar to the males ( Figs. 42 , 43 ), almost completely green. Tegmina ventral margin whitish-creme with feeble light-brown spots above. Ovipositor (Fig.45) longer than head and pronotum together, evenly curved upward, lower margin straight on basal 3/4, distal fourth spinulated on upper and lower margins; basal lobe of ovipositor (Figs. 45, 46) robust, sub-trapezoidal; subgenital plate (Fig. 47) represented by a large subrectangular structure projected distally and divided by a median suture, proximal portion sculptured with transversal grooves; basal sclerites sub-triangular. Measurements (mm) females. Body length from vertex to end abdomen: 20.5 ± 2.5 (18.7–22.2). Pronotum length: 3.4 ± 0.4 (3.1–3.7). Tegmina length: 11.9 ± 0.6 (11.5–12.8). Cephalic femur length: 5.2 ± 1.2 (4.3–6.0). Mid femur length: 6.0 ± 1.4 (5.0–7.0). Caudal femur length: 13.5 ± 2.4 (11.8–15.2). Ovipositor: 8.1 ± 0.2 (7.9–9.0).
diagnosis · Plazi
Diagnosis. P. tuliensis n. sp. , is morphologically similar to P. cieloi . However, it may be distinguished by the different shape of males’ stridulatory file ( Fig. 36 vs. 21) and different acoustic signals (Barrientos-Lozano et al . in prep.); the terminal tergite distal projection is less produced than in P. cieloi ( Fig. 37a vs. 22a); the cerci ( Figs. 37a , 38 , 39 vs. 22a, 23, 24), the epiproct ( Fig. 37 b vs. 22b) and the subgenital plate ( Fig. 39 vs. 24) are different from P. cieloi analogous structures. In females the subgenital plate is sub-rectangular (in P. ci eloi is sub-quadrate) (Fig. 47 vs. 31). Females may also be differentiated by association to the collection site.
