Bouchardium chillygonzalesi & B. mariae - Red-edged White-legged Quadrate Toktokkies (newly described species)

The well-known White-legged Toktokkie Dichtha cubica has been split into three species and a new genus was erected for them in:
Kamiński MJ (2024) New taxa of Afrotropical toktokkies (Coleoptera: Tenebrionidae: Molurina) from the Natural History Museum of Basel. Zootaxa 5446(1): 77–87.
OPEN ACCESS.
https://doi.org/10.11646/zootaxa.5446.1.4.

Three species are now known and described:

Bouchardium cubicum (Guérin-Méneville, 1845) - Common White-legged Quadrate Toktokkie

  • Shiny blackish, only antennae and legs with whitish tomentum
  • Underside: Prosternal process (1) rounded (in lateral view).
  • Elytra ampliated: Elytral disc relatively wide covering sides of epipleura in dorsal view. Elytral disc relatively flat. Elytra entirely black.
    Distribution: Northern South Africa, Botswana, Zimbabwe

Bouchardium chillygonzalesi Kamiński 2024 - Narrow Red-edged Quadrate Toktokkie

  • Elytra with two red stripes along the sides of the disc, red edges of disc with corrugated margins.
  • Underside: Prosternal process with elongate appendages.
  • Elytra narrow: Elytral disc relatively narrow leaving sides of the epipleura exposed in dorsal view. Elytral disc relatively flat.
    Distribution: South Africa (North West), Zimbabwe,
    Type locality: Hartebeestpoort dam

Bouchardium mariae Kamiński 2024 - Wide Red-edged Quadrate Toktokkie

  • Elytra with two red stripes along the sides of the disc, red edges with almost smooth margins
  • Underside: Prosternal process rounded (in lateral view).
  • Elytra ampliated: Elytral disc relatively wide covering sides of epipleura in dorsal view. Elytral disc distinctly convex.
    Distribution: Botswana, South Africa (Limpopo), Zimbabwe, Mozambique
    Type locality: Francistown, Botswana

(1) The prosternal process is a part in the middle of the prosternum, a posterior projection between the insertion of the forelegs. It has appendages on the tip only in B. chillygonzalesi

Key to the species of Bouchardium (was in Dichtha)

1' Prosternal process with elongate appendages. Elytral disc relatively narrow dorsally exposing sides of the epipleura. C4 ovipositor plates short ... B. chillygonzalesi
1" Prosternal process rounded. Elytral disc relatively wide dorsally concealing the epipleura. C4 ovipositor plates elongate ... goto 2

2' Elytra entirely black. Elytral disc relatively flat ... B. cubicum
2". Elytra with 2 red stripes along disc sides. Elytral disc convex ... B. mariae
