The female subgenital plate is very short, expanded laterally and rectangular, with retractable emarginations, these stay hidden when the subgenital plate is not lowered. The male cercus is very short, with the compressed projection greatly reduced and broadened; the inner margin is dark and denticulate.   Description. Chromatic standard.( Fig. 1A–B) The entire body is covered with reddish brown or dark brown macules. A distinct black or dark brown band extends dorsally from the fastigium of vertex to the IX abdominal tergite. Two order slightly lighter and irregular bands appear in each side of abdomen.  Head.Fastigium of vertex with truncate apex, continuous with fastigium of front and dorsal area smooth; the eyes are little and rounded; the frons and genae smooth, but the multiple irregular macules make them appear rough ( Fig. 1C).  Thorax.Pronotum produced posteriorly, covering most/all of the short wings. Cephalic margin of pronotal disk truncate, caudal margin sub-rounded. Cephalic margin of lateral lobes of pronotum obtuse, ventro-cephalic angle a little obtuse, caudal margin sinuous, covering most of the humeral sinus. Prosternum bearing two long spines.  Legs.All genicular lobes of the anterior and the external mid femora without spines, provided with a blunt tooth. All of the others are armed with little spine. Lower margin of anterior femur has two spines internally and none externally. Lower portion of fore tibia presents six spurs (articulate spines) on each margin. Mid femur has three spines on ventro-external border and unarmed internally. Middle tibia with 8–9 spurs on ventro-external margin and six internally. Dorsal portion bearing a single minute spine internally, externally smooth. Lower portion of hind femur armed with 2–4 spines internally and 6–7 externally. Hind tibia above with 12 spines internally and 14–16 externally, ventrally with 6–8 little spurs on external margin and 4–5 on the inner one.   FIGURE 1.  Uchuca almeirina  sp. nov.male. 1A) Dorsal view of body; 1B) Lateral view of body; 1C) Frons; 1D) Left tegmen; 1E) Stridulatory file; 1F) Dorsal view of X tergite; 1G) Ventral view of subgenital plate; 1H) Dorsal view of left cercus, Arrow) Digitate process; 1I) Lateral view—left; 1J) Lateral view—right.   FIGURE 2.The phallus of  Uchuca almeirina  sp. nov.everted. 2A) Posterior view; 2B) Colorful scheme of posterior view; 2C) Anterior view; 2D) Colorful scheme of posterior view.  Wings.Tegmina extremely short, rudimentary, reaching only the beginning of the first abdominal tergite, almost or completely covered by the caudal margin of pronotal disk, with a few veins and dark brown coloration for all the border ( Fig. 1D). The stridulatory file on the left tegmen has 275 microscopic teeth ( Fig. 1E). The posterior wings are very delicate and extremely reduced, with hyaline coloration and stay completely covered by the little tegmina.  Abdomen.Tenth tergite emarginated and bifid ( Fig. 1F). The subgenital plate is long, basally broad, and narrower at apex, which is deeply emarginated, provide with two little styles apically. The emarginations are very close to each other ( Fig. 1G). Cerci very short ( Table 1). The cercus compressed projection is very reduced and broad, with the inner border darker than the rest of the cercus and denticulate ( Fig. 1H–J); the basal digitate process of the cercus is short, slender and hyaline, formed by two segments (Arrow Fig. 1H). Phallic complex provided with a pair of very slender and up curved titillatory processes, each one ending in a titillator’s sclerite provided with a unique spine; and two sclerites of ventral fold of dorsal lob longer than broad ( Fig. 2A–B)—in Montealegre-Z & Morris (2003)this structure was called sclerotized area. Ejaculatory vesicles are ovoid. On the anterior portion of dorsal lobe there are two slender and membranous processes that here we call membranous processes of dorsal lobe(Fig; 2C–D).   Comments.This species resembles  Uchuca pallida( Caudell, 1918)e  Uchuca peruviana( Caudell, 1918)because all three are micropterous. However, it is easily distinguished from the Caudell species by the black or dark brown band that extends dorsally from the fastigium of vertex to the IX tergite, once neither of the Caudell’s species have this band, especially on the abdomen, where Caudell affirms that the lateral is darker than the dorsum.   Female.Females are morphologically similar to male, but are slightly more robust ( Table 1). The coloration is also similar ( Fig. 3A–B). The ovipositor is strongly up curved ( Fig. 3D). The X tergite is slightly shorter than the male but the general form is similar ( Fig. 3C). The subgenital plate is very short, rectangular, expanded laterally and with retractable emarginations, which stay hidden under the subgenital plate (Arrow Fig. 3E) and only are projected when the plate is lowered (Arrow Fig. 3F). Meso-posterior portion of plate without sulci or invaginations. The cerci are simple, conic ( Fig. 3C). The legs are similar to male, but the middle tibiae have two spines on the upper internal portion. The hind tibiae are dorsally armed with 12 spines internally and 15–17 externally and ventrally with five little spurs on external margin and 5–6 on the inner border.  Body Size.  Uchuca almeirina  sp. nov.is a very delicate and small species. The anterior and mid legs are very short and the wings are very reduced, mainly in females. The male cerci are also very reduced. The measurements of body are given in Table 1.   Etymology.The specific epithet refers to typelocality, the city of Almeirim.   Distribution.This species is known only to the typelocality: Monte Dourado, Almeirim, Pará, Brazil. 1288040403 2005-04-30 MPEG A.
