Redescription

(Female lectotype, Fig. 4) Body surface granulated. Head. Lateral view (Fig. 4A, B): protuberant and slightly conical eyes with a flattened base; vertex and fastigium visible between eyes; antennal groove situated between lower margin of compound eyes; frontal costa elevated. Frontal view (Fig. 4D). Fastigium of vertex slightly conic; frontal costa bifurcation placed between compound eyes with narrow scutellum; fascial carinae between both superior ocelli; median ocelli placed between fascial carinae and frontal carina, but not touching on the base by frontal carina; antennal groove situated between lower margin of compound eyes and medial ocelli. Dorsal view (Fig. 4C). Vertex with distance between eyes as long as horizontal diameter of eyes; medial carina conspicuous and continuing towards frontal costa; area of fastigium to occiput granulated; occipital area visible and anterior margin of pronotum distant from the eyes. Pronotum. Macropronotal and flattened dorso- ventrally. Lateral view (Fig. 4A, B). Anterior margin of pronotum truncated and slightly elevated; median carina slightly undulated, prozonal carina and humero-apical carina visible and short, not reaching the sulci; extralateral carina inconspicuous; ventral sinus present; lateral lobe with anterior margin truncated and without spine; tegminal sinus present; length of infrascapular area shorter than length of fore tibiae; two deep sulci between prozona and humero-apical carina; paranota granulated and triangularly shaped; humero-apical carina continuous to external lateral carina and both parallel to median carina. Frontal view (Fig. 4D). Lateral lobes of pronotum projected and directed sideways. Dorsal view (Fig. 4C). Dorsum granulated; prozonal carina visible and short, not reaching the sulci; median carina continuous; humero-apical carina conspicuous; anterior and posterior margin of pronotum truncated; lateral lobe directed sideways. Sternomentum. The sternomentum could not be checked due to it being glued on card. Wings. (Fig. 4A, B). Tegmina and hindwings visible; tegmina oval, sublanceolated shape; hindwings dark brown and surpassing pronotum apex. Legs. Fore legs (Fig. 4A, B, D). Fore femur flattened laterally, dorsal and ventral margins of femur carinated with three undulations in the dorsal margin and one in ventral margin; tibia as long as femur. Middle legs (Fig. 4A-C). Middle femur shieldlike shape, flattened laterally and strongly foliaceous; dorsal and ventral margin slightly undulated; ventral margin expanded, with rounded teeth (crenated) near tibia; femur longer than tibia. Hind legs (Fig. 4A, B). Dorso-external and ventro-external of femur granulated; antegenicular tooth conspicuous; dorso-external carina and ventro-external carina conspicuous; transversal ridges visible on external surface; tibia not visible and hidden behind the femur. Abdomen. (Fig. 4A, B). Sternites not visible due to specimen glued on card; ovipositor valves short and robust, superior margin of dorsal and ventral valve with teeth. Measurements (in Hancock, 1907). Total length of female body: 16.5 mm; pronotum: 14.5 mm; hind femur: 7 mm.

Male (paralectotype, Fig. 5)

Similar to female, except: Head. Frontal view (Fig. 5D). Fastigium straight. Pronotum. Lateral view (Fig. 5A, B). Humero-apical carina not continuous to external lateral carina. Measurements (in Hancock 1907). Total length of male body: 15 mm; pronotum: 13 mm; hind femur: 6 mm.

Comments

Eomorphopus granulatus Hancock 1907 has been recorded from Guyana, French Guyana, Suriname, and Brazil. E. granulatus is the only species of Eomorphopus with type species housed at ANSP. Both specimens of the museum have labels, with the female labeled as “Type” and the male labeled as “Allotype”/”Paratype” . As the author did not designate the holotype in the original description, we designated the female as the lectotype and, consequently, the male specimen became the paralectotype. We believe that this redescription will facilitate species recognition in the future. In his description, Hancock (1907) indicated that the body was subtly granulated and cinereous or fuscus-cinereous (ash-colored; gray tinged with blackish), see Smith (1906). Actually, this type has overall brownish-yellow and brown color.
