Tribe Garciaitettigini Cadena-Castañeda , trib. nov.
Type genus: Garciaitettix n. gen., here designated.
Description. Body small to medium size and slender (6–12 mm.) ( Figs. 86A View FIGURE 86 , 93 View FIGURE 93 ). Head exserted above pronotum; the upper margin of the vertex lower than the level of the upper margin of the compound eyes ( Figs. 88A View FIGURE 88 , 89A View FIGURE 89 , 91A View FIGURE 91 , 92A View FIGURE 92 , 93A View FIGURE 93 ). In frontal view, face rectangular, noticeably taller than wide; fastigium concave; medial carinae of the vertex slightly elevated or not; lateral carinae surrounding the inner margin of the eyes and extending into a horn on each side, which exceeds the elevation of the medial carina; vertex approximately 1 to 1.5 times wider than the eye ( Figs. 87C View FIGURE 87 , 89C View FIGURE 89 , 90C View FIGURE 90 , 92D View FIGURE 92 , 94B View FIGURE 94 ). In lateral view, medial carina not protruding beyond the eyes ( Figs. 89A View FIGURE 89 , 90A View FIGURE 90 , 91A View FIGURE 91 , 92B View FIGURE 92 ) (only moderately in Stalitettix gen. nov. ( Fig. 93A View FIGURE 93 )). Anterior margin of the vertex concave, fastigium of the vertex not forming a longhorn, and dorsum without fossulae. Antennae groves located lower than the lower margin of the eyes, about half the height of the rostrum and scutellum; antennae mid-sized with 10–15 segments. Scutellum narrow or moderately widened, not exceeding the width of the scape; frontal costa mid-sized, and bifurcation generally at the level of the lower margin of the eyes ( Figs. 87C View FIGURE 87 , 89C View FIGURE 89 , 91C View FIGURE 91 , 92D View FIGURE 92 ). Eyes rounded in frontal and lateral views, medium to small in size, protruding from the upper section of the head, occupying a quarter or a fifth of the cephalic capsule ( Figs. 86A View FIGURE 86 , 89A View FIGURE 89 , 91A View FIGURE 91 , 92A View FIGURE 92 ). Lateral ocelli placed between the middle part or between the inferior part of the eyes, near the base from where each branch of the fascial carinae diverges; medial ocellus located close to the lower margin of the scutellum; palpi with last three segments flattened, first two segments short and nearly cylindrical ( Figs. 87C View FIGURE 87 , 89C View FIGURE 89 , 91C View FIGURE 91 , 92D View FIGURE 92 ). Thorax. Pronotum generally slender, reaching or exceeding the tip of the abdomen ( Figs. 87A View FIGURE 87 , 92B View FIGURE 92 , 93 View FIGURE 93 ) (except Garciaitettix gen. nov. ( Fig. 96 View FIGURE 96 )). Pronotal disc with a straight anterior margin and a pointed posterior margin, dorsally almost flat ( Figs. 85C View FIGURE 85 , 88B View FIGURE 88 , 92C View FIGURE 92 , 94A View FIGURE 94 ); median carina with moderate or conspicuous undulations, distributed mainly in the anterior half of the pronotum ( Figs. 85A View FIGURE 85 , 86A View FIGURE 86 , 91A View FIGURE 91 ). Lateral lobes of pronotum rectangular in lateral view, lower margin well projected to the sides, directed slightly sidewards, with rounded or acute apex ( Figs. 85C View FIGURE 85 , 87B View FIGURE 87 , 88B View FIGURE 88 , 92C View FIGURE 92 , 94A View FIGURE 94 ); humeral angle wide, obliquely concave; infrascapular area thin, and projecting over half the length of the abdomen, over the third or fourth segment ( Figs. 86A View FIGURE 86 , 92B View FIGURE 92 , 93A View FIGURE 93 , 95A View FIGURE 95 ) (widened only in Garciaitettix gen. nov. ( Fig. 96A View FIGURE 96 )); lateral area narrow or poorly developed, arising over the dorsal undulation of the infrascapular area. Wings. Most species winged, with lanceolate tegmina and hind wings reaching the apex of the pronotum or surpassing it ( Figs. 85A View FIGURE 85 , 87A View FIGURE 87 , 92A View FIGURE 92 ). Legs. Fore and mid-femora compressed, elongated, and thin, with undulations on the dorsal and ventral margins, forming small extensions or not. Mid femur carinated above. Hind femur variying in some taxa, usually with smooth dorsal and ventral margins, but tubercles and lappets on the external face of the femur may occur; genicular and antegenicular teeth moderately or well-developed (noticeably developed in Trigonofemora ( Figs. 90B View FIGURE 90 , 91A View FIGURE 91 )). Hind tibia scarcely ampliated near the apex; the first and third segments of the hind tarsi equal in length. Abdomen. Male: eighth and ninth segments moderately constricted, compared to other Neotropical tribes of the subfamily. Subgenital plate cupuliform, as long as or longer than the last abdominal sternite; apex of the subgenital plate rounded (rarely with a small incision). Cerci conical and reduced. Female: Epiproct triangular or oblong, with or without medial groove. Subgenital plate mainly rectangular, with a small extension or notch at the apex. Ovipositor valves narrow, both the lower and upper ones with similar thickness; inferior valve not conspicuously covered by the lateral edges of the subgenital plate; valves armed with teeth of medium or small size.
MAP 6. Distribution of Garciaitettigini trib. nov. species.
Genera included. Chiriquia Morse, 1900 , Trigonofemora Hancock, 1906 , Devrieseium gen. nov., Stalitettix gen. nov., and Garciaitettix gen. nov.
Distribution. Mainly in South America, with Chiriquia serrata Morse, 1900 , found between Panama and Nicaragua (Maps 4 and 6).
Remarks. This new tribe is proposed once it does not fit the diagnostic characters of Metrodorini and Otumbini trib. nov. The known genera are monotypic, except Chiriquia .According to observations in iNaturalist, most species of this new tribe are camouflaged among bryophytes.
