Tobochares sp. C: Short et al. (2021)

Type material examined.

Holotype (male): "Brazil: Goiás: Cristalina: -16.87004, -47.61716; 947 m; Cristalina Balneario Lajes; seepage on rock next to river; 4.iii.2018; Benetti and team; BR18-0304-02B." (INPA). Paratypes (26 exs.): Brazil: Goiás: Same data as holotype (26, INPA, SEMC including DNA Voucher SLE1505).

Differential diagnosis.

Tobochares goias can be easily recognized from most species in the Tobochares sulcatus species group by its elytral punctures seemingly uniformly distributed, not forming clear longitudinal rows, therefore completely lacking elytral striae (Fig. 4D). This character makes it similar to T. benettii, from which it can be distinguished by its dark brown coloration, with paler (yellowish to orange) lateral margins of pronotum and elytra (Fig. 4D, E), the posterior elevation of the mesoventrite forming a low and uniform curved transverse ridge (Fig. 4F), and by characters of the aedeagus (Fig. 11B).

Description.

Dorsal surfaces of body dark brown with paler outer margins of pronotum and elytra (Fig. 4D, E); head slightly darker; mouthparts and antennae yellowish; legs yellowish to brown with paler tarsi (Fig. 4F). Ground punctation on head, pronotum and elytra moderately marked. Head: Eyes in dorsal view with anterior margin oblique, posteriorly directed, and outer margins continuous with outline of head; in lateral view, eyes emarginate to about half the length of eye (Fig. 2A, B). Maxillary palps slender, slightly shorter than width of head, uniformly yellowish in color (Fig. 2A). Thorax: Elytra with slightly defined rows of punctures, not forming grooves (Fig. 4D). Elevation of mesoventrite with a low transverse ridge (Fig. 4F). Metaventrite with distinct median, broad, ovoid glabrous area extending along posterior two thirds (Fig. 4F). Abdomen: Abdominal ventrites uniformly and very densely pubescent. Aedeagus (Fig. 11B) with basal piece 0.2 × the length of a paramere; widest point of parameres (near base) nearly as wide as basal width of median lobe, with outer margins very slightly sinuate, and rounded apex; median lobe fusiform, with widest point slightly apicad of midpoint, broadly rounded at apex; gonopore situated at apex of median lobe.

Etymology.

Named after the Brazilian state of Goiás, from which the species is known.

Distribution.

Only known from the type locality in the central Brazilian state of Goiás . This is the first and currently only species of Tobochares reported from south of the Amazon River (Fig. 12).

Life history.

This species was collected on wet rock along the margins of the Ribeirão das Lejas. See Fig. 14C.
