Fig. 5E–G

Discodon nigrocephalum Pic, 1949: 6 .

Discodon nigrocephalum – Delkeskamp 1977: 255 (catalogue).

Diagnosis

Similar to D. obscurior and D. tenuecostatum sp. nov. by the general coloration. It differs from these species by the wider head (Fig. 5F), apparently nearly as wide as the pronotum, the antennae black, and the elytra coriaceous, rough, without costulae (Fig. 5E).

Type material

Lectotype (here designated) BRAZIL • ♂; São Paulo, Vale do Rio Pardo; Dec. 1898; E. Gounelle leg.; “ Museum Paris Coll. M. Pic ”; MNHN, Paris EC13556 (Fig. 5E–G).

Remarks

We were not able to examine the type specimen of D. nigrocephalum nor found similar specimens that could be attributed to this species. However, the photographs of the lectotype, deposited at the MNHN, Paris, enable the distinction between D. nigrocephalum on the one hand and D. obscurior and D. tenuecostatum sp. nov. on the other hand.

Distribution

Brazil (São Paulo state) (Fig. 16).
