Platytettix uniformis Bruner, 1910: 100. Lectotype: male, BRAZIL. Depository: ANSP.
Metrodora uniformis: Günther, 1939: 297.
Material examined. Lectotype. 1 Male, Pará (ANSP). 1 Male. BRAZIL, Pará, Belém, Museu Paraense Emílio Goeldi—Campus de Pesquisa [the museum research campus]; 01°27’07”S, 48°26’38”W. [40m]; 09-13.I.2014. Pitfall; R. S. Sovano leg. (MPEG).
Emended description. Male. Robust and tiny-sized (6 mm). Body granular, and moderately rugose (Figs. 5A, 5B, 6). Coloration. Generally dark brown with some scattered black spots on the pronotum and femora, except for the antennae, distal part of the tibiae, and tarsomeres, which are ocher (Figs. 5A, 5B). Head. Medial carina moderately protruding in the middle of the eyes in lateral view (although more conspicuous than in other species of the genus, not as conspicuous as in other genera of the tribe Metrodorini) (Figs. 7A). Antennae with 14 segments; lateral ocelli located near the fork of the frontal costa (Figs. 5C, 7B, 7C). Thorax. Pronotal hump moderately elevated and curving regularly backward (Figs. 5A, 6A, 7B); apex of the pronotal disc acuminated (Fig. 6B); lower margins of the lateral lobes rounded (Figs. 6B, 7C). Legs. Fore femur moderately dilated, basally constricted, and then expanding, rectangular with gently undulating dorsal and ventral margins; outer surface of the fore femur with two long and thin bristles arising near the ventral margin (Fig. 7D); mid-femur rectangular, longer than wide and not as dilated as the fore femur, dorsal margin slightly curving throughout its length, ventral margin undulating, and with two short extensions (Fig. 7E). Hind femur conspicuously robust compared to other species, antegenicular and genicular teeth poorly developed; hind tibia armed with six small spines on each dorsal margin (Figs. 5A, 6A). Abdomen unmodified. Epiproct triangular, dividing the tenth tergite, and with subdivisions, a pentagonal section at the base, where the last tergite is divided, another subtriangular division at the apex, and on each side an ovoid or subrectangular division (Fig. 8A). Cerci cylindrical, but distally conical, thinner and diverging to the sides (Figs. 8A, B). Pallial plates ovoid, divided in the middle into a less sclerotic structure, delimited by the two furrows contiguous with the pallial hooks (Fig. 8C). Subgenital plate short and slightly divided at apex; penultima sternite quadrangular and longer than the subgenital plate (Fig. 8D).
Measurements (in mm). CFP: 6. PL: 5. PLB: 3.4. FF: 1.3. FL: 1.2. MFL: 1.6. MTL: 1.2. HL: 3.2. HW: 1.6. HTL: 2.7.
Remarks. This species was originally described from two specimens from an unknown locality in Pará State and two from Benevides, also in Pará State (Brazil) (Fig. 5). One of the specimens from the latter locality was considered an immature male, the remaining three were females (Bruner 1910). Later, Günther (1939) transferred this species to Metrodora and reported additional specimens from Nouveau Chantier (French Guiana) and Paramaribo (Suriname). Subsequently, Grant (1957) designated a female from Pará (with no precise locality) as the lectotype (Fig. 5) and the male from Benevides as the lectoallotype (i.e., paralectotype), which he claimed to be an adult male, not a nymph, as Bruner (1910) had thought. Recently, Cadena-Castañeda & Cardona-Granda (2015) recorded the species for the Colombian Amazon, marking the westernmost record for this taxon.
