Diagnosis

Anthrenus (s. str.) senegalensis ( Fig. 5A View Fig ) has a single dark amber ocellus on the vertex, just below the level of top of eyes and a notch on the lower inner margin of the eye. Face covered in pale yellow scales, which in some specimens are a shade darker on the vertex. The pronotal and basal elytral integument is very dark brown. Away from the base and towards the elytral apices the integument becomes redder. Elytra are covered in dark and light brown scales. The scales on either side of the small, dark, triangular scutellum are pale brown. The scales behind and below the humerus are pale brown and pale brown scales continue from the humerus along the outer margin. At about midway, pale brown scales leave the margin and form a downward curved, narrow fascia that crosses the elytra just beyond halfway. The fasciae on each elytron meet at the elytral suture, with more pale brown scales forming a vertical line on either side of the suture that extends towards but does not reach the elytral apices. Just before the apices the pale brown scales sweep left and right along the elytra to form a sub-apical fascia. Four small spots consisting of white scales sit in the mid-fascia accentuating the downward curve of the fascia. There are a few white scales in the sub-apical fascia and at the base of the elytra. All other scales are a darker brown. The pronotum is covered in brown scales of varying hue, paler towards the lateral margins and darker on the pronotal disk, with two spots of dark brown on the posterior margin on either side of the scutellum. Ventrite ( Fig. 5B View Fig ) integument is dark red and covered in yellow-tinted scales on the disk, fading to a broad margin of yellow ochre scales. The scales on the outer, anterior corners of each sternite are marginally darker.

The 11-segmented antenna ( Fig. 5C View Fig ) is entirely red, with little to no variation in hue among the various antennomeres. All components of the legs are similarly red. The anterio-ventral faces of the femora are covered in pale brown scales.
