description: Paraoaxaca cuitlateca sp. nov. Aguilar-Roldán, Gómez-Tapia, Mariño-Pérez & Sanabria-Urbán
DIAGNOSIS AND MORPHOLOGICAL AFFINITIES. Males of cuitlateca sp. nov. differ from all other Paraoaxaca species by the short, spatula-like furcula with subtriangular tips pointing forwards (Fig. 11A) in combination with the spherical subgenital plate with a tongue-like tip pointing inwards (Fig. 11C–D); or by the unilobulated lophi of epiphallus (Fig. 15A), combined with the short dorsal aedeagal valves with dorsally flattened, wrench-like apices (Fig. 15C). Other differences are shown in Table 2. Despite male genitalia of cuitlateca sp. nov. and cohni sp. nov. most closely resemble each other, key differences exist. For example, the former species has unilobulated and stout lophi of epiphallus (compared to bilobulated as in cohni). Further comparisons are made in Table 2.
SPECIES DESCRIPTION. Coloration (Fig. 5A–D) and general morphology (Fig. 8A–D): 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. 11A–D): supra-anal plate subtriangular with rounded posterior border. Furcula moderately short (but larger than in ottei) and spatula-like with subtriangular tips pointing forwards in dorsal view (Fig. 11A). Cerci conical and straight, tapering gradually towards the apex, nearly as long as the supra-anal plate (Fig. 11A–B). Subgenital plate spherical with a tongue-like tip in the posterior border pointing inwards in dorsal view (Fig. 11C) and with a concave ventral border in lateral view (Fig. 11D). Female terminalia (Fig. 11E–F): supra-anal plate triangular. Furcula not developed. Cerci conical, nearly one-half the length of the supra-anal plate (Fig. 11E). Dorsal valves of ovipositor lanceolate with tips curved dorsally (Fig. 11F). Ventral valves of ovipositor with a ventral tooth projecting posteriorly and tips curved ventrally (Fig. 11F). Male genitalia (Fig. 15A–D): epiphallus well sclerotized, bridge almost straight (Fig. 15A); ancorae short, triangular, and curved ventrally (Fig. 15A–B); anterior projections curved inwards with sharp pointy apices (Fig. 15A–B); lophi stout and unilobulated in dorsal view (Fig. 15A) with anterior-internal tooth notably developed dorsally in lateral view (Fig. 15B). Endophallus with dorsal valves short (barely surpassing the sheath of ectophallus), dorsally flattened and wrench-like apices (Fig. 15C). Ventral valves conical, nearly as long as the dorsal valves in lateral view of endophallus (Fig. 15D).
EXTERNAL VARIATION (in mm). Males (n = 26): body length: 11.22–16.72 (13.98 ± 1.4), pronotum length: 2.77–3.37 (3.06 ± 0.15), prozona length: 1.68–2.67 (2.09 ± 0.19), metazona length: 0.71–1.23 (0.95 ± 0.14), metazona/prozona ratio: 0.32–0.72 (0.46 ± 0.1), and hind femur length: 8.01–10.07 (8.75 ± 0.45). Females (n = 38): body length: 13.11–20.59 (18.27 ± 1.76), pronotum length: 3.13–4.75 (4.02 ± 0.27), prozona length: 2.26–3.18 (2.77 ± 0.23), metazona length: 0.85–1.73 (1.19 ± 0.21), metazona/prozona ratio: 0.27–0.76 (0.43 ± 0.11), and hind femur length: 8.91–11.81 (10.77 ± 0.56).

DISTRIBUTION, HABITAT AND TEMPORAL OCCURRENCE. Individuals of cuitlateca sp. nov. have been collected in five lowland (sea level— 440 masl) localities up to 127 km apart in southeastern Michoacán and northwestern Guerrero, within the Pacific lowlands and the Sierra Madre del Sur biogeographic provinces. Adult specimens of cuitlateca sp. nov. have been collected in September and November in weedy-bushy ruderal habitats surrounded by tropical deciduous forests (Fig. 17E–F).
ETYMOLOGY. This species is named after the Cuitlateca, an ethnic group that inhabited northwestern Guerrero and disappeared at the beginning of the 20 th century. The epithet cuitlatec a is a feminine noun in apposition.
