Curicta johnpolhemi Keffer,2000, 107:145–148 (Original description); Moreira et al., 2011: 48–49 (List of species and distribution).
Diagnosis – This species can be recognized by the following characteristics: It is the smallest species within the genus, featuring two profemoral teeth (Fig. 4D), and the prominent carinae on abdominal tergum VII are connected, forming a dome (Fig. 4A–B) (Keffer, 2000).
Supplemental description – Specimens examined: 39 females and 31 males including the holotype: Body length, 16.1; profemur length, 5.0; siphon, 8.5 (Fig. 4A). Additional females: Body length, 16.0–17.3; profemur length, 5.0–6.3; siphon, 8.5–9.5.Female genitalia. Gonapophysis-1 elongate, with dorsal angles formed more anterior than posterior, well-sclerotized.In lateral view, gonapophysis-1 subtriangular, also well-sclerotized. Gonapophysis-2 dorsomedially convex, lanceolate (Fig.4F), flattened basally, slightly convex medially, projecting posteriorly beyond posterior margin of gonapophysis-1 (Fig.4F). Description of male (Fig. 4 B-E): Body length, 15.0–16.5 (Fig. 4B); length profemur, 5.0–5.8; siphon, 8.0–9.0. Color dark-brown. Head: Eye width 0.3× interocular distance. Vertex broadly convex; without median longitudinal carina. Lobe of antennal segment II less than 0.5× length of segment III. Thorax: Elongate pronotum; lateral length 1.7× posterior width.Lateral margins parallel at middle and diverging posteriorly and anteriorly. Transverse furrow incomplete. Median longitudinal furrow very shallow; obsolete in posterior 2/3. Median longitudinal ribs rounded. Lateral longitudinal furrows shallow. Lateral longitudinal ribs rounded. Granulations on median furrow and humeral lobes.Posteroventral extension of pronotum located on ventral midline at junction of prosternum and mesosternum. Width of scutellum less than its length with indistinct tridentate pattern; longitudinal section of lateral serrations appears convex medially. Procoxa 0.50× profemoral length. Two profemoral teeth (Fig. 4D); distance from base of femur to tip of anteroventral profemoral tooth 0.52× total length of profemoral. Profemur moderately convex beyond profemoral teeth. Single row of cusps in profemoral groove in distal two-thirds, with no teeth in groove distally (Fig. 4E). When extended posteriorly, metafemur extends only to posterior margin of sternum VI. Lateral margins of hemelytra subparallel from apex of scutellum to base of membranes, narrower anteriorly and posteriorly. Metathoracic wings fully developed with Mp and CuA veins converging in posterior third of wing. Prominent carina on bilateral plates of last abdominal tergum (VII), forming a convex arc in distal two-thirds, reaching its highest elevation along midline, and appearing tomentose distally. Abdomen: Parasternum of last segment without distal processes. Posterior margin of operculum extending beyond distal margin of parasternum. Male genitalia: Parameres elongate and curved inward apically.
Note – The species C. johnpolhemi was previously known from only a single female; the holotype was described from the state of Minas Gerais, Brazil.Through the collection of both sexes from various streams and by correlating them with the previously described female, as well as comparing them with the holotype, it became feasible to describe the male.

Distribution – Brazil: Minas Gerais (Keffer, 2000), Maranhão (this work) (Fig. 5).
Note – This represents the first record of Curicta johnpolhemi outside the type locality and the first records from the state of Maranhão and northeastern Brazil. This species appears to inhabit the Cerrado biome but remains poorly collected in other sites.
