Figs 6, 7, 8, 19
Diagnosis.
The black postalar macrosetae (Fig. 6 B), the epandrium strongly excavated at mid-inner dorsal margin (Fig. 7 A, F, H), and the subepandrial sclerite somewhat trapezoidal at middle (Fig. 8 D) should promptly distinguish this species from its congeners.
Description.
Male (Fig. 6 A). Body Length: 13.2 mm; wing length: 7.1 mm. Head (Fig. 6 A – D). Similar to C. aysu sp. nov. except as noted: Thorax (Fig. 6 A, B, D) postalar macrosetae black. Legs (Fig. 6 B). Leg I. Tibia with posterior row of four long black macrosetae from basal 1 / 4 to apex. Leg II. Femur with anterior row of four strong black macrosetae (basalmost white). Tibia with macrosetae wholly black. Leg III. Femur with anteroventral row of short, strong, and sparse black macrosetae (basalmost white). Terminalia (Figs 7, 8). Similar to C. aysu sp. nov., except as noted: Epandrium strongly excavated at mid-inner dorsal margin (Fig. 7 A, F); subepandrial sclerite somewhat trapezoidal at its middle (Fig. 8 D).
Female. Unknown.
Type examined material.
Holotype • ♂ (MZUSP) labelled: “ BRASIL: MS [state of Mato Grosso do Sul]: Porto Murtinho | Faz. São Fernando – km 12 | 21°36'30"S, 57°49'02"W | 19–31.I.2008 | Nihei, S., Figueiredo, R. & Almeida, J. | (col.) ” “ HOLOTYPE | Cardiasilus dangeloi | Soares, Camargo & Lamas [red label] ”. Holotype condition: Good, left postpedicel broken off, abdomen glued to thorax with remains of glue obscuring pruinosity of tergites one to three, terminalia dissected and stored in microvial at the same pin.
Remarks.
The new species is remarkably similar to C. aysu sp. nov., differing only in the color of postalar macrosetae black (Fig. 6 B), anterior row of macrosetae on mid femur wholly black, only the basalmost macroseta white (Fig. 6 A), epandrium strongly excavated at mid-inner dorsal margin (Fig. 7 A, F, H) and subepandrial sclerite somewhat trapezoidal at middle (Fig. 8 D). In C. aysu sp. nov. the postalar macrosetae are yellow (Fig. 2 C), the anterior row of macrosetae on the mid femur is white, the mid-inner dorsal margin of the epandrium is weakly excavated (Fig. 3 A) and the subepandrial sclerite is somewhat diamond-shaped (Fig. 4 D). The epandrium strongly excavated medially at inner margin and the lack of a dorsal preapical process also differs C. dangeloi sp. nov. from C. ruda sp. nov.
Distribution.
Brazil (state of Mato Grosso do Sul) (Fig. 19).
Etymology.
The new species is named after Gio D’Angelo (INPA), an artist, photographer, and myrmecologist who is the partner of the first author and deeply passionate about scientific illustration. Gio also kindly created the illustration for Fig. 20.
