Oaxaca (Paraoaxaca) ottei sp. nov. Aguilar-Roldán, Gómez-Tapia, Mariño-Pérez & Sanabria-Urbán

DIAGNOSIS AND MORPHOLOGICAL AFFINITIES. Males of this species are distinguished from other Paraoaxaca species by their strongly reduced furcula with rounded tips pointing sidewards ( Fig. 9A View FIGURE 9 ), in combination with a subtriangular subgenital plate with rounded posterior border pointing dorso-posteriorly ( Fig. 9C–D View FIGURE 9 ); or by their paddle-shaped lophi of epiphallus ( Fig. 13A–B View FIGURE 13 ), in combination with short dorsal aedeagal valves with laterally flattened and bilobulated apices ( Fig. 13C–D View FIGURE 13 ). Further comparisons are made in Table 2 View TABLE 2 . Interestingly, the lophi in ottei sp. nov. approaches the shape seen in tlapaneca sp. nov. ( Fig. 16A–B View FIGURE 16 ), but the curvature of the bridge of epiphallus notably differs among them, being only slightly curved in ottei sp. nov. Moreover, these two species occupy opposite ends of the subgenus range ( ottei sp. nov. in the north, tlapaneca sp. nov. in the south; Fig. 6 View FIGURE 6 ). While ottei sp. nov. also shares the short dorsal aedeagal valves with cohni sp. nov. and cuitlateca sp. nov. (which are regionally closer), the forms of these structures are unique among the taxa ( Table 2 View TABLE 2 ; Figs. 13–15 View FIGURE 13 View FIGURE 14 View FIGURE 15 , C–D).

SPECIES DESCRIPTION. Coloration ( Fig. 4C–D View FIGURE 4 ) and general morphology ( Fig. 7A–D View FIGURE 7 ): similar in variation as described for the subgenus, except for the coloration of central and dorsolateral light stripes of the dorsal surface of the body that in this species ranges from white to ivory. Male terminalia ( Fig. 9A–D View FIGURE 9 ): supra-anal plate triangular with rounded apex. Furcula nearly touching dorsally and strongly reduced with rounded tips pointing sidewards ( Fig. 9A View FIGURE 9 ). Cerci conical and straight, tapering gradually towards the apex, nearly as long as the supra-anal plate ( Fig. 9A–B View FIGURE 9 ). Subgenital plate subtriangular in dorsal view ( Fig. 9C View FIGURE 9 ) with rounded posterior border pointing dorso-posteriorly and ventral border slightly concave ( Fig. 9D View FIGURE 9 ). Female terminalia ( Fig. 9E–F View FIGURE 9 ): supra-anal plate triangular. Furcula not developed. Cerci conical, nearly one-half the length of the supra-anal plate ( Fig. 9E View FIGURE 9 ). Dorsal valves of ovipositor lanceolate with tips curved dorsally ( Fig. 9F View FIGURE 9 ). Ventral valves of ovipositor with a ventral tooth projecting posteriorly and tips curved ventrally ( Fig. 9F View FIGURE 9 ). Male genitalia ( Fig. 13A–D View FIGURE 13 ): epiphallus well sclerotized, bridge slightly curved anteriorly ( Fig. 13A View FIGURE 13 ); ancorae short, triangular, and curved ventrally ( Fig. 13A–B View FIGURE 13 ); anterior projections curved inwards with rounded apices ( Fig. 13A–B View FIGURE 13 ); lophi prominent, paddle-shaped and developed posteriorly with anterior-internal tooth moderately developed dorsally in lateral view ( Fig. 13A–B View FIGURE 13 ). Endophallus with dorsal valves short (barely surpassing the sheath of ectophallus) with apices laterally flattened and bilobulated ( Fig. 13C–D View FIGURE 13 ); the dorsal and ventral lobules are slightly curved backwards or forwards, respectively ( Fig. 13D View FIGURE 13 ). Ventral valves conical and nearly slightly shorter than the dorsal valves in lateral view of endophallus ( Fig. 13D View FIGURE 13 ).

EXTERNAL VARIATION (in mm). Males (n = 15): body length: 13.74–16.96 (15.34 ± 0.83), pronotum length: 2.63–3.88 (3.21 ± 0.4), prozona length: 1.86–2.67 (2.27 ± 0.28), metazona length: 0.59–1.19 (0.89 ± 0.19), metazona/prozona ratio: 0.25–0.61 (0.39 ± 0.09), and hind femur length: 8.02–9.34 (8.65 ± 0.36). Females (n = 16): body length: 15.08–19.87 (18.29 ± 1.36), pronotum length: 3.97–4.7 (4.25 ± 0.23), prozona length: 2.7–3.39 (3.01 ± 0.18), metazona length: 0.87–1.63 (1.16 ± 0.18), metazona/prozona ratio: 0.31–0.56 (0.39 ± 0.07), and hind femur length: 8.46–10.84 (10.05 ± 0.59).

DISTRIBUTION, HABITAT AND TEMPORAL OCCURRENCE. This species has been only collected in two geographically closed (less than 10 km apart) and lowland (L08 and L07, 396–481 masl) localities around central Colima within the Pacific lowlands biogeographic province. So far, ottei seems to be allopatrically distributed in the most septentrional portion of the subgenus range. Adults ( Fig. 4C–D View FIGURE 4 ) and mating pairs ( Fig. 17A View FIGURE 17 ) of this species have been found at the end of the rainy season in different years (in September 1959 and 2024) in weedy-bushy ruderal habitats at the edge of tropical deciduous forests ( Fig. 17 A–B View FIGURE 17 ).

ETYMOLOGY. The specific epithet is a patronym in honor of Daniel Otte for his great contributions to the taxonomy of Melanoplinae grasshoppers in Mexico, including some of the material revised here was collected by him.
