Type species: Odopoea signoreti Stål, 1864 , here designated.

Included species.— Dyticodopoea azteca ( Distant 1881) , new combination; Dyticodopoea diriangani ( Distant 1881) , new combination; and Dyticodopoea signoreti ( Stål 1864) , new combination.

Diagnosis.—The genus Dyticodopoea n. genus can be distinguished from all genera of Zammarini except Odopoea , Adusella and Pygmaeodopoea n. genus by a combination of the three tarsomeres, the separate attachment of the median and cubitus anterior veins on the basal cell, and the width of the pronotum being less than 1.5 times the width of the head which Goemans (2010) determined to be the characters separating Odopoea from all other Zammarini . Species of Odopoea can be distinguished by the timbal cover that clearly exposes the dorsal timbal, lobate lateral branches of the uncus, recurved posteroventral margins of the pygofer, the transverse posterior margin in the female opercula, and the posterior extension at the posterior notch in female sternite VII, while species of Dyticodopoea n. genus possess a timbal cover that almost completely covers the timbal, a flattened median uncus lobe that is bent when viewed from the side, posteroventral margins of the pygofer are flat, the posterior extension of the female opercula, and the posterior extension of the posterior notch beyond the transverse posterior margin in female sternite VII. The head being not as wide as the mesonotum, the postclypeus being as wide as the frons when viewed from above, trochantin 1 being split obliquely, the male opercula overlapping on the midline, fore wing cubitus anterior 1 being longer beyond the crossvein than proximal to the crossvein, the radial and radiomedial crossveins are parallel, the tripartite uncus formed from the thin, extended, and laterally arching median uncus lobe with lateral branches extending near the base of the median uncus lobe, the very small dorsal beak not extending to the length of the dorsal pygofer shoulders, the semicircular female opercula, and the lack of a posterior extension at the posterior notch in female sternite VII distinguish species of Adusella from Dyticodopoea n. genus. In addition, species of Odopoea are distributed in the Greater Antilles of the Caribbean, species of Dyticodopoea n. genus are distributed in Central America, species of Pygmaeodopoea n. genus are known only from Mexico, and species of Adusella are found in Argentina, Bolivia and Peru ( Sanborn 2019). The most similar genus is Pygmaeodopoea n. genus but the timbal cover is triangular with a straight dorsal margin rather than semicircular or triangular with a concave dorsal margin, the opercula has a transverse posterior margin, the lateral pygofer has a sinusoidal margin rather than a smoothly curved margin, the pygofer dorsal shoulders are pointed rather than smoothly curved, and the dorsal beak is short, barely longer than the dorsal shoulders, instead of being elongated well above the dorsal shoulders of the pygofer, the uncus has a bifurcated terminus rather than a single semicircular or transverse terminus, and the uncus lacks the semicircular indentation when viewed from the side found in Dyticodopoea n. genus.

Description.—Medium to small sized cicadas, body size similar in both known species; length of body 22.50–25.30;

length of fore wing 32.80–36.80; width of fore wing 9.20–12.30; length of head 3.00–4.00; width of head including eyes 7.75–9.70; width of pronotum including suprahumeral plates 10.10–13.70; width of mesonotum 7.65–9.50. Head ( Figs. 1– 2 ): Head including eyes slightly wider than base of the mesonotum. Frons and anteromedial vertex strongly inclined, forming a right angle with the dorsal head, vertex at area of ocelli about as long as frons. Ocelli closer to each other than to eyes. Postclypeus apex flaccidly curved when viewed from above, anterior of frons not as wide as the postclypeus apex visible from above. Postclypeus roof-shaped (flatly arched) ventrally, central sulcus very small only near ventral apex, the transverse ridges prominent, rostrum reaching to hind coxae. Seven segmented antennae. Pronotum ( Figs. 1–2 ): Shorter than mesonotum with lateral expansions extended much further than eyes, not prominently angulated but angularly rounded, the anterior margin curved very slightly, the posterior margin straight. Mesonotum ( Figs. 1–2 ): Longer than pronotum, cruciform elevation with open V-shaped posterior margin covering dorsal metanotum, metanotum extends laterally beyond wing groove. Trochantin 1 not split obliquely into two truncated, humpbacklike distensions, with a notch on either end of the split. Legs: Fore femur primary spine finger-like adpressed to femur, secondary spine smaller, wider at base, upright or slightly angled distally, tertiary spine very small. Hind tibiae with two tibial spurs laterally and two tibial spurs medially. Opercula: Male opercula large covering tympanal cavity, semicircular with rounded posterior margin, not extending medially to the midline, female opercula similarly shaped but smaller reaching medially only to middle of meracanthus, meracanthus triangular, elongated and tapering to a point, female meracanthus of similar shape to male for each species extending beyond middle of female opercula. Wings ( Fig. 1 ): Fore wings narrow, with rounded apex, fore wing length to width ratio 2.99–3.26, narrow costal membrane widening only near the base, with eight apical cells, the origins of the median vein and cubitus anterior veins are separated by slightly more than the vein width at the basal cell, basal cell longer than broad, pterostigma present, cubitus anterior 1 shorter beyond crossvein than proximal to crossvein, radial and radiomedial crossveins not parallel. Hind wing with six apical cells, anal vein 3 curved at distal end, anal lobe broad, slight infuscation in anal cells. Abdomen ( Figs. 1, 5 ): Roof-shaped, about as long as the distance between the apex of the postclypeus and the cruciform elevation, lateral margins parallel at base until the abdomen begins narrowing posteriorly to the genitalia, tympana concealed by opercula. Timbal cover roughly triangular in D. azteca new combination or roughly semicircular with concave or convex upper margin exposing the dorsal timbal, timbal almost completely covered in D. signoreti new combination ( Fig. 9 ), anterior apex semicircular not bent mediad, timbal extending below wing bases. Male sternite VIII V-shaped. Female sternite VII with a posterior extension of the notch beyond the transverse posterior margin adjacent to the notch and a curved posterolateral margin. Female abdominal segment 9 with dorsal beak well defined, posterior margin sinuate ovipositor sheath extending slightly beyond the length of the dorsal beak. Male genitalia ( Figs. 7–8 ): Pygofer dorsal beak elongated, broadly triangular, distal shoulders rounded, upper pygofer lobe absent, posteroventral margins of the pygofer flat, basal pygofer lobe extending about half the length of the pygofer with pointed tip, median uncus lobe bent at right angle at half length, smoothly rounded apex, lateral uncus curving to middle of median uncus lobe forming a semicircular notch when viewed from the side, male aedeagus simple, curving in a gentle arc with terminal membrane.

Etymology.—The name is in reference to the western distribution (Gr. dytikos, western) of the species classified in the new genus compared to the distribution of the true species of Odopoea in combination with the previous genus in which the species were classified.

Distribution.—Species of the genus have been recorded previously from Honduras, Mexico, and Nicaragua ( Metcalf 1963; Duffels and van der Laan 1985; Sanborn and Maes 2012; Maes et al. 2012; Sanborn 2013). The first records for Guatemala are reported here.
