description: Ichthyotettix inexpectatus n. sp.
Examined material and type depository. Mexico, Morelos, Tepozteco, 26.V.1976, 1 male Holotype (CNIN); Michoacan, Sta. Maria Almaoatitlan, Morelia, 14.IX.1980, 1 male paratype (CFP).
Diagnosis. Male tenth abdominal tergite produced into a broad, inflated process, as long as wide, covering the epiproct, wide more than half the total width of same tergite; male cerci robust, straight, without inner tooth at inner margin and apex flattened dorso-laterally; epiproct in form of a triangle; prosternal tubercle asymmetrically pyramidal, with caudal surface almost vertical, with subquadrate apex; epiphallus with bridge forming with its lophi an anchor like structure; aedeagal valvae of penis sinuose, short, regularly subconical, with finely squamous surface. Processes arising from ramus of cingulum distant and diverging from dorsal view.
Description. General colour brown-gray; lower third of lateral lobes of pronotum whitish. The green form unknown. Body smooth, cylindrical in male. Antennae filiform, triangular in section. Head conical, not distinctly triangular in dorsal view, especially in male (Fig. 28). Eyes prominent, round-ovate; frontal profile strongly oblique, nearly straight, median and lateral frontal carinae distinct. Vertex very slightly convex or almost horizontal in profile, median carinae present. Fastigium of vertex shorter than wide, somewhat elliptical. Pronotum cylindrical in male, rugose, with small dense granules present in metazona as well in prozona; disc with anterior and posterior margins truncate and very slightly excised, median and lateral carinae present, extremely reduced, transverse sulci not strong. Lateral pronotal lobes with anterior margins oblique, inferior margin slightly sinuous, with a small tooth right before posterior angle and posterior margin straight and vertical, the infero-posterior angle a right angle (Figs.
28, 31). Prosternal tubercle asymmetrically pyramidal, with caudal surface almost vertical, apically subquadrate. Mesosternal interspace just narrower than a mesosternal lobe in male and as wide as a lobe in female. Tegmina, hind wings and tympana absent. Tenth abdominal tergum of male produced into a broad, inflated process, as long as wide, covering the epiproct, wide more than half the total width of same tergite; it can be apically emarginated, forming two closed rounded swellings (Figs. 36, 37). Epiproct elongated, subtriangular, with acutely rounded apex, restricted at base. Male cerci robust, straight, without inner tooth at inner margin and apex flattened dorso-laterally (Figs. 19, 22). Male subgenital plate rounded and rather inflated (Fig. 36). Epiphallus as in I. mexicanus (Fig. 46), with bridge forming with its lophi an anchor like structure. Aedeagal valvae of penis sinuose, short, regularly subconical, with finely squamous surface. Processes arising from ramus of cingulum distant and diverging from dorsal view (Figs. 49, 52). Female unknown.
males (2) range average st. dev. body length 19.23–20.0 19.62 0.54 pronotum length 2.40–2.80 2.60 0.28 prozona 1.90–2.20 2.05 0.21 metazona 0.50–0.60 0.55 0.07 hind femur length 9.23 9.23 0.00 Etymology. From the Latin word inexpectatus (= unexpected) being this new species identified within the material of I. mexicanus during the description of the previous new species.
Distribution. Ichthyotettix inexpectatus n. sp. is to date known only from Michoacan and Morelos states in Mexico (Fig. 57).
