Description of the neotype of D. miersii .

Length: 78 mm, without antennae and anal legs.

Color: dark brown. Head and first tergite reddish brown; last two tergites pale brown. Legs yellow, middle portion greenish gray.

Cephalic plate: with fine punctuations, without furrows or depressions ( Fig. 1 ).

Antennae: with 17 antennomeres, the first three ones with some scattered strong bristles and without short hairs. Fourth antennomere with a few hairs on the ventral side. The other antennomeres with yellow hairs and some long scattered bristles.

Forcipular coxosternum: anterior margin straight or just a little convex, with light lateral depressions from which at each side originates an elongated transversal depression, which is directed towards the midline and almost reaches the transversal furrows. A longitudinal furrow joined to a branched transversal furrow. A small round depression at the posterior border. Prefemoral process with strong internal appendix, whose apex forms a wide dorso­ventrally flattened lobe ( Fig. 2 ).

Dental plates formed by two long, narrow, chitinous lobes, more elevated on the sides than in the middle, but lacking typical teeth; anterior margin slightly granulated ( Fig. 2 ).

Tergites: First tergite with anterior semicircular pit (the cephalic plate hides the pit sometimes). Paramedian sutures reaching from tergite III (or V) to XXII. Last tergite (XXIII) with a light depression in the posterior border and without furrows ( Fig. 3 ). Sides of tergite VI to XX with a light depression. Lateral carinas reaching from tergite VI to XXI (or XXII). Lateral carinas of tergite VI and XXI (or XXII) noticeable only at their anterior border. Last tergite without carinas, presenting only a membranous line that separates tergite from coxopleura.

Sternites: with fine punctuations, without furrows or depressions. Last sternite with a simple median depression, posterior margin with median concavity ( Fig. 4 ).

Coxopleura: Dorsal margin curved outward, its posterior corner ending at a strong, sclerotized point. Porous field almost reaching the lateral borders of the tergite ( Fig. 5 ). Coxopleural appendices long, parallel and pointed.

Legs: Legs I to XVIII (or XIX) with two tibial spurs, XX and XXI with one, XXII and XXIII without tibial spurs. Legs I to XXI with one tarsal spur, XXII and XXIII without tarsal spur. Last two pair of legs (XXII and XXIII) long, with biarticulated tarsus. Prefemur of the right anal leg with a strong ventral spine and a smaller dorsolateral spine (left anal leg teratologically modified) ( Fig. 6 a, 6b).

Range of character variation in the examined Neotropical material. ­ Body length of adult specimens varies from 56 mm to 85 mm. Some specimens are pale brown, with head, first and last two tergites brownish red. Specimens from Paraná (Foz do Jordão) present color like neotype, but the last two legs with middle portion greenish gray. Other specimens greenish brown. Head, first and last two tergites brownish red. Legs yellow except for the last two (or three) pairs with middle portion of femur, tibia, and two tarsus grayish. Forcipular coxosternum like neotype, in all specimens there is a light roundish depression in the middle of coxosternum. This character is hard to see in alcohol­preserved specimens. Tergites and sternites like neotype, but the posterior margin of the last sternite can be straight (some specimens) or with a more or less distinct median concavity.
