Type species. Glyphuchus sculpturatus Stål, 1860, by monotypy. Diagnosis. Glyphuchus can be recognized by its curved, swollen labrum, head longer than wider, with a short acute preocular projection, pronotum with flattened, lateral expansions and a small projection in the anterolateral angles, and abdominal segments with serrated aspect, pronounced laterally. Redescription. General morphology and color. Body oval, longer than wide. General body color mostly green when alive (fig. 1), mottled, with markings varying from dark brown to black on head, pronotum, scutellum, hemelytra, and connexival segments; scutellum with 1+1 yellowish calli on either side of disk and four spots of same color on pronotal cicatrices. Preserved specimens (figs. 2, 3) green-yellowish; dark and yellowish markings present. Head. Subrectangular, longer than wide, with dark punctures scattered throughout; eyes rounded, globose, ocelli closer to eyes than to each other.Acute preocular projection present, not exceeding half the length of scape.Mandibular plates longer than clypeus, convex in outline, apices rounded, contiguous in front of clypeus. Labrum large, thick, strongly curved forward (fig. 3D). Bucculae elevated, rounded anteriorly and posteriorly, widened posteriorly, much shorter than rostral segment I. Rostrum reaching base of abdominal segment III (2 nd visible segment). Antennae 5-segmented, segments I-III cylindrical, segment IV claviform, segment V fusiform. Antennal segment I shorter than mandibular plates. Antennal segments I and II yellowish with black dots, antennal segment III dark brown at basal two thirds and lighter at apex, segment IV dark brown, segment V basally yellow and apically dark brown. Thorax. Pronotum subrectangular, declivent anteriorly (fig. 3D), laterally expanded (expansions flattened); anterior angles projecting acutely laterad, lateral margins sinuate. Transversal line behind the cicatrices of pronotum elevated (fig. 3D), with four light spots (fig. 2A) slightly elevated. Scutellum long, reaching almost to apex of abdominal segment VI (fig. 3A), with lighter outlines in the lateral margins of the frenal lobe. Scutellar fovea depressed, scutellar disk more elevated than the postfrenal lobe. Apical margins of scutellum elevated on both sides, but not in the middle. Mesosternum slightly depressed medially, metasternum flat, hexagonal. Spout-like peritreme short, not reaching middle width of evaporatorium (fig. 3B, per). Hemelytra. Lateral margins convex, longer than scutellum. Dark punctures scattered across coria, forming three dark patches on each corium: one near the scutellar fovea, one in the middle of corium, and one at apex of the radial vein. Membrane short, not reaching the apex of connexival segment VII, darker in live specimen. Legs. Yellow in preserved specimens, with many large brown dots on femora and tibiae. Forecoxae much closer to each other than middle and hindcoxae. Tibia strongly sulcate, excavated dorsally. Femora with a subapical dark brown annulus. Tarsi 3-segmented, middle segment shortest, apical segment longer than basal; middle and apical segments dorsally yellow, ventrally apex of middle segment and apical segment dark brown. Claws dark brown with yellowish base. Abdomen. Spiracles II partially concealed by metaepimeron, spiracles III–VII oval with black outline. Abdominal venter light yellow with many dark scattered punctures, most of which bear a thick brownish seta; middle portion of venter almost unpunctured. Middle of sternite VII with a dark brown longitudinal patch, occupying the whole sternite length in male, and restricted to a small anterior semilunar area in female. Sternites III–VII projected laterally, serrated. Connexival segments III–VII yellow, with black markings on anterior and posterior portions; same color pattern on lateral margins of sternites. In male, abdominal segment VIII (fig. 2D, VIII) bearing spiracles VIII, these circular with black outline (fig. 2D, sp), smaller than spiracles III–VII. Male genitalia. (figs. 2C–E) Genital capsule subquadrangular, laterally sinuous. Dorsal rim (dr) concave, darker than adjacent dorsal area; posterolateral angles (pla) strongly projected posteriorly, apically rounded, slightly sinuous in posterior view (fig. 2C). Ventral rim (vr) with deep, U-shaped, median excavation, presenting brownish bristles along the rim (figs. 2D, E). Segment X (X) longer than wide, projected posteriorly but not reaching apex of posterolateral angles. Parameres (par) apically dark, acute, not projecting beyond posterolateral angles. Female genital plates. (fig. 3C) Valvifers 8 (vf8) trapezoidal, base larger than apex, mesially contiguous from base to apex.Apical portion of valvifers 8 almost straight, angulated to each other, edges rounded.

Impicticollis have unique colouration within the genus Dinidor; see text for explanation. ** Except for D. jograziae, body length measurements based on Durai (1987). Comments. The study of the specimens allows us to conclude that the correct identification of the species cited in Genevcius et al. (2016) is actually D. saucius. Some diagnostic characteristics pointed out by Durai (1987) in her key to separate D. mactabilis and D. saucius, for instance the colouration of the costal margin of the corium, are incongruent with the type specimens of both species, and the additional material examined. Indeed, the costal margins of hemelytra in red, orange or light brown is a characteristic seen in every species of the genus Dinidor, and cannot be used to separate the species. Some of the other characters used to diagnose the species, such as the width of the median coloured stripe along the pronotum, showed great variation within the species, and are not reliable for the correct identification of both species, D. mactabilis and D. saucius. Diagnostic characters for the five species of Dinidor with similar colouration (excluding D. braziliensis and D. impicticollis) are presented in Table 1. Prior to this work, the distribution of D. saucius has been scarcely addressed. St��l (1870) described the species from Rio de Janeiro (Brazil).Although Durai (1987) only mention Brazil for the distribution of D. saucius, additional material examined by the author were collected in the neighbouring State of Esp��rito Santo (dashed in the map), expanding the distribution of the species. Rolston et al. (1996) only cited Rio de Janeiro, and as the two previous works, no specific locality information was provided. Genevcius et al. (2016) recorded D. saucius (as D. mactabilis, see above) from the state of S��o Paulo (S��o Bernardo do Campo). Aside from the new locality records from the states of Rio de Janeiro and S��o Paulo, we extend the known distribution of D. saucius southwards by at least 600km, to the state of Santa Catarina. The distribution pattern of D. saucius seems to include only the Atlantic Rain Forest region, in southern and southeastern Brazil (Fig. 9).
