Tagalis inornata inornata stål, 1860

description: Tagalis inornata inornata Stål, 1860
As mentioned above, T. inornata was described based on the holotype female from Rio de Janeiro (Stål 1860), Brazil. However, “Rio de Janeiro” has been used to designate both the city and the state within which the city is located. Thus, it is not possible to be sure about the exact locality where the holotype could have been collected in the nineteenth century. In an attempt to prevent confusion, the specimens selected to be studied here, were from three localities within this state, not far from the city of Rio de Janeiro.
Morphological remarks. Female. (Figs. 44–46). Total length (in mm): to tip of abdomen: 4.9–5.4; to tip of forewings: 5.4–6.5. General color: testaceous to yellowish with darkened regions (Fig. 44). HEAD: Brownish black in dorsal region, with brighter areas adjacent to eyes and antennal insertions in some specimens. Posterior lobe more darkened, with yellowish longitudinal median furrow; ventral region brighter, testaceous or darkened to variable extent, or with brownish spots or short straight stripes in variable positions. Clypeus darkened to brownish in all but one specimen in which it was clear. Eyes of medium size. Strong and long setigerous brownish spines inserted anteroventrally and posteroventrally in relation to eyes, and another pair ventrally, in space between eyes and neck. Antennal segment I yellowish, with sub-basal faint and incomplete darkened ring in some specimens; blackish apically; one specimen with large brownish ring in sub-basal third; segments II–IV blackish; segment IV with preapical dilatation and pale apex. Rostrum testaceous or variably brownish, specially laterally; segment I slender, elongated, curved, reaching posterior margin of eyes, with pair of darkened stout spines approximately at midpoint; PLATE 5.

THORAX: Anterior lobe yellowish to orange with two faint rounded dorsal swellings anteriorly (Fig.45) and posteriorly; integument of hind lobe of pronotum somewhat rugous; humeral rounded angle showing somewhat large and prominent blackish stripe that reaches midpoint of lateral portion of posterior lobe; in some specimens, humeral apex is yellowish with pair of darkened spots on adjacent lateral and medial areas. Lateral shallow ridge not prominent, becoming almost imperceptible in its posterior third. Prosternal processes with an anterodorsal setigerous spine and posteroventral seta. General color of metathorax brownish-black, sometimes brighter in dorsal and/or sternal area, and almost entirely testaceous in few specimens; whitish in area just above middle and hind coxae. Scutellum spine, tubercle and metanotum spine completely blackish or variably clear over their extent (Fig. 45). Legs yellowish, femora with faint straight subapical brownish rings that may be somewhat incomplete or imperceptible in some legs; tibiae with faint sub-basal variably darkened rings. Extremities of tibiae and distal half of first and second tarsal segments faintly darkened in some specimens. Procoxae elongated, with long darkened spine in basal third of anterior surface, and two short spines on inner face; one in middle and other apically. Middle and hind coxae ovoid; trochanters triangular, tapering; protrochanter with four spines on inner side. Profemora swollen, armed on ventral surface with a row of spines of different interpolated sizes, including four to six longer ones intermixed; on inner side, another row of four bigger spines that may be accompanied by another two to four smaller ones in basal third. Protibiae covered with long and short hairs, more numerous in apical portion, where small spines stand out, with three curved, darkened and very strong spines on inner surface; two of these in basal half and third approximately at or just distal to midpoint of tibia. Forewings (Fig. 44) extending beyond tip of abdomen; grayish, enfuscated, somewhat darkened at base, especially in anal cell area (nomenclature follows Villiers 1943a); veins brighter in basal third of wing; pterostigma brighter at apex, where it is almost whitish in some specimens, as well as in small adjacent area, forming short stripe directed anteriorly; another two small clear to whitish spots of variable size may be evident: 1—in area adjacent to proximal portion of M in distal cell; and 2—in middle of area between R, R+M and C+ Sc. Hind wing hyaline. ABDOMEN: Sternite I and basal half of sternite II somewhat darkened, sometimes blackish, except median carina which is always testaceous; in some specimens, narrow irregular median transverse faint reddish stripes, interrupted in middle portion of segment, in sternites II–VI; these may just be irregular reddish spots, or may be absent in some or all segments.
