For further (already published) data, see Gerstmeier (2018, 2019). This concerns the “species” Eucymatodera sp. 1 till Eucymatodera sp. 3 ., all paratypes, here.

Diagnosis. Head and pronotum with conspicuous punctation.Antennae more-or-less reaching base of pronotum (when laid back), antennomeres dilated from A5 onwards, longer than wide. Elytral base margined, punctation with a basal seta. Prosternal length more-or-less like procoxal diameter. AMP not rectangular, bulging only in front. Gular pads large, separated or adjoined.

Description. Length: 4.5–9.9 mm.

Head black, with dense, conspicuous punctation; labrum slightly and broadly emarginate or broadly rounded; clypeus with coarse punctation (diameter larger than punctation on head), not emarginate. Antennae more-or-less reaching base of pronotum (when laid back), antennomeres dilated from A5 onwards, longer than wide, A11 conspicuously shorter than A9+A10, not bulbous, more-or-less narrow, only very slightly constricted towards tip.

EyW: 0.16–0.38 mm; EyD: 0.52–1.06 mm; EyD/EyW: 2.78.

Pronotum black, subparallel in front, conspicuously constricted towards base, slightly sinuate before middle; with dense, conspicuous, more-or-less deep punctation.

PL: 1.04–2.36 mm; PW: 0.8–1.7 mm; PL/PW: 1.35.

Elytra totally black or with an orange (yellow-brown) transverse fascia (sometimes double banded) or an orange fascia more-or-less triangularly extended towards base (but far away from scutellum) and narrowly along the suture towards apex, apex broadly orange. Elytral base margined, elytra subparallel, slightly to conspicuously dilated towards apex. Punctation in 10 rows, extending beyond the middle, diameter of punctation conspicuously smaller than interstices, becoming smaller behind the orange transverse fascia, disappearing at apex or becoming irregular; punctation with a basal seta; interstices with microsculpture.

EL: 3.04–6.92 mm; EW: 1.36–3.21 mm; EL/EW: 2.19.

Legs yellow-brown to red-brown (or dark brown), tibial base sometimes darkened.

Lower surface. Head and thorax dark brown to black brown, abdomen yellow-brown to red-brown. Gula transversely wrinkled or smooth (in one case), gular pads large, separated or adjoined. Prosternal length more-or-less like procoxal diameter. AMP not rectangular, bulging only in front. Mesoventrite very coarsely, deeply (with variable diameter) and densely punctate. Metaventrite finely and diffusely punctate.

Genitalia. See Fig. 25 . Same genitalia in all variations.

Distribution: Namibia, Republic of South Africa.

Etymology. In honor of my friends Doris, Ralf († 2024) and Jochen Schindler, who have always given me a warm welcome and extensive support during all my trips to Namibia.
