Tagalis inornata inornata Stål, 1860

Gil-Santana, Hélcio R., 2011, Three new species of Tagalis Stål (Hemiptera: Heteroptera: Reduviidae: Saicinae) from Brazil, Zootaxa 2996, pp. 33-48 : 40-46

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.
