Treatment

Cornitermes longilabius Silvestri, 1901: 5 ; Silvestri 1903: 59 –60, 127 [imago (text Fig. 13 View FIGURES 13 , Pl. Fig. 103), soldier (Pl. Fig. 105), worker (Pl. Fig. 105)]; Desneux 1904: 37 ( Termes ); Holmgren 1912: 50 ( Cornitermes subgenus Labiotermes ); Emerson & Banks 1965: 20 –24 ( Labiotermes ) [imago ( Fig. 5 View FIGURES 5 ), soldier ( Fig. 6 View FIGURES 6 )].

Syntypes: Imagos, soldier, workers (DEZA, AMNH and MCSN), not examined.

Typelocality: Brazil: Mato Grosso, Cuiabá.

Imago. Described and illustrated by Emerson & Banks 1965: 20–22.

Soldier ( Figs. 7 View FIGURES 7 A–B, 11G). Described and illustrated by Emerson & Banks 1965: 22–23. Additional measurements are presented in Table 2 View TABLE 2 .

Comparisons. See L. brevilabius and L. leptothrix .

Worker ( Figs. 7 View FIGURES 7 C–F, 13G, 15M–N, 16G). Head capsule and postclypeus with numerous bristles. Pronotum with numerous bristles on anterior lobe and a row of bristles on posterior margin. Mesonotum with a few bristles near lateral sides. Front coxa with a rounded hump near base. Front and middle trocanters and tibias with numerous short and thick bristles. Antenna with 15 articles. Fontanelle large and rounded. Enteric valve 6 fingerlike ridges of unequal sizes, covered with fine spines. Mixed segment with two mesenteric lobes; large lobe oval; small lobe very small and narrow. Measurements in Table 3 View TABLE 3 .

Comparisons. The worker of L. longilabius can be recognized by the presence of short and thick bristles on the front and middle trocanters. In all other species, these spinelike bristles are present only on the femur and coxa. The enteric valve is also distinct ( Fig. 16 View FIGURES 16 G).

Geographical distribution. L. longilabius occurs in Brazil and Paraguay ( Fig. 19 View FIGURES 19 ), and most records are located in the Cerrado biome.
