Metrodora concinna View in CoL : Bolívar, 1887: 249.

Otumba concinna View in CoL : Cadena-Castañeda & Cardona-Granda, 2015: 479.

Material examined. Neotype. The neotype hereby designated contains the following data: “ Coll. Br. v. W. Ob. Mayali u. Urubamba, Peru, Staudinger ” identified as Chiriquia concinna by K. Günther; deposited in NHMW.

Remarks. This species was originally described as Metrodora concinna based on a male from Paramaribo, Suriname, deposited in the collection of NHMW Vienna, Austria ( Bolívar, 1887). Then, Hancock (1907) placed this species in Chiriquia , a classification maintained in entomological literature until Cadena-Castañeda & Cardona-Granda (2015) moved it into Otumba . Following this combination, Itrac-Bruneau & Doucet (2022), in their study of Tetrigidae from Guyana, recorded a probable presence of this species in that country. D. concinnum comb. nov. has a wide distribution, being reported in many localities in Suriname (type locality), in Peru without mentioning additional specimens to the type specimen ( Hancock, 1907), in Brazil, Pará, in a locality also named Pará ( Rehn, 1916), this locality refers to the current city of Belém ( Levi, 1964), in Taperihna, Pará, Brazil (we were not able to determine this locality precisely) and Bucay, Ecuador ( Günther, 1939), Esmeraldas, San Lorenzo, Ecuador ( Buzzetti & Devriese, 2007). Although several specimens have been recorded since its description, the type specimen is lost.

A neotype specimen is designated as the name-bearer of the species ( Fig. 92 View FIGURE 92 ). It is supported by the following reasons ( ICZN 1999 Art.75): 1. The location of the only type specimen is Paramaribo, Surinam. It was deposited in NHMW, but Paris (1994) mentions that the type specimen is lost (she visited that collection but did not find the type specimen). The holotype male specimen could not be traced from its original description (Arts. 75.3.1., 75.3.4.), but K. Günther (1939), studied several specimens, among them, the male here selected as a neotype. Günther was an academic authority on the study of tetrigids, so his identification is reliable, as it fits the original description of the species. 2. Not having specimens from the type locality, a male from a nearby and available locality of similar geological characteristics was designated (Arts. 75.3.5, 75.3.6; recommendation 75A ICZN). 3. A detailed description is written of the neotype that is in agreement with the general idea of the identity of this species, differentiating itself from other taxa, ensuring the recognition of the designated specimen, and conveying a consensus in identifications and wide distribution that characterizes the species, ensuring that most identifications from the past are correct (Arts. 75.3.2, 75.3.3, 75.3.5; recommendation 75B). 4. The neotype is deposited in NHMW, a collection of a recognized scientific institution, which maintains adequate facilities to preserve the types and makes them accessible for study (Art. 75.3.7).

Genus Stalitettix Cadena-Castañeda & Tavares , gen. nov.

Type species: Tettix spinifrons Stål, 1861 , here designated.

Description. Slender and elongated body, moderately granulate ( Fig. 93 View FIGURE 93 ). Head slightly compresso-elevated ( Fig. 93 View FIGURE 93 ). In frontal view, vertex almost as wide as 1.5 times the width of an eye, anteriorly concave; medial carinae short and moderately elevated; frontal costa bifurcation at the middle of the eyes; lateral carinae surrounding the upper inner margin of the eyes, and protruding gently upwards from the eyes, like two small horns; scutellum moderately widened; fascial carinae moderately elevated, with ramification of fascial carinae divergent, especially on the lower section; antennae groves much lower than the ventral margin of eyes, in the middle length of each branch of the fascial carinae, almost at middle of the frons; antennae with 14 segments; lateral ocelli between the lower margin of the eyes, near the base from where each branch of the fascial carinae diverges; medial ocellus located close on the lower margin of the scutellum; palpi with last three segments yellowish and flattened, first two segments short and nearly cylindrical ( Figs. 94B View FIGURE 94 , 95C View FIGURE 95 ). In lateral view, face subvertical; carinae of the vertex little produce between the eyes; fastigio-fascial angle little convex; fascial carinae slightly emerging between the antennae and rounded, above and below slightly sinuate; eyes rounded, with a rounded dorsal surface, straight ventral margin and slightly elevated than vertex ( Figs. 93A View FIGURE 93 , 95A View FIGURE 95 ). Thorax. Pronotum elongated, surpassing the tip of abdomen and hind femora ( Figs. 93 View FIGURE 93 , 95A View FIGURE 95 ); pronotal disc almost straight anteriorly and acute apically; pronotal disc granulated, with post humeral spots ( Figs. 94A View FIGURE 94 , 95B View FIGURE 95 ); median carina with an undulation in the anterior section of the pronotum ( Fig. 95A View FIGURE 95 ). Lateral carinae undulated in dorsal and lateral views; humeral angles concave; lower margin of lateral lobes flattened and projected to the sides, with apex pointed; posterior margin of lateral lobe with a mid-undulation ( Figs. 94A View FIGURE 94 , 95B View FIGURE 95 ); infra-scapular area mid-sized and moderately wider, ending at the level of the first to second abdominal segments; lateral area extending to the apex of the pronotum and as wide as the infrascapular area is in lateral view ( Figs. 93 View FIGURE 93 , 95A View FIGURE 95 ). Wings. Tegmina narrow and lanceolate, black in color, and with yellowish venation ( Fig. 93 View FIGURE 93 ). Hind wings reaching the apex of the pronotum ( Fig. 95A View FIGURE 95 ). Legs slender. Fore and mid-femora dorsally and ventrally undulated; fore and mid-tibiae sulcated above. Hind femora with a lappet in the middle of the external surface ( Fig. 95B View FIGURE 95 ); antegenicular and genicular teeth poorly developed. First and third segments of the hind tarsi equal in length.

Female. Unknown.

Species included. Stalitettix spinifrons ( Stål, 1861) , comb. nov. only.

Distribution. Brazil, Amazon (between Pará and Rodônia states), and Mata Atlântica (Atlantic Forest, between Rio do Janeiro and Bahia States) (Map 6).

Comparison. Stalitettix gen. nov. differs from the other genera of the tribe by the medial carina of the vertex protruding slightly in the middle of the eyes, and the tegmina being narrow and lanceolate. This new genus resembles Devrieseium gen. nov. because both with the lower margin of the lateral lobes of the pronotum acute and the external surface of the hind femur without tubercles or lappets, distinguishing them from Trigonofemora , with conspicuously developed genicular and antegenicular teeth. Lappets are present in both Garciaitettix gen. nov. and Trigonofemora , and moderately developed in Chiriquia .

Etymology. This genus is dedicated to the memory of the naturalist Carl Stål in recognition of his significant contributions to orthopteroids and other insects. The ending - tettix, common in the genera of pygmy grasshoppers, is added. The gender of the name is femenine.
