Original description translated from German:
Henosepilachna tricolorata spec. nov.
At first glance, similar to H. natalensis [now Chnootriba natalensis], but slightly broader and, above all, with a different position of the spots: 2, 2, 2, 1. Basic and marginal coloring of the elytra, of the head and pronotum exactly as in H. natalensis. Spots, however, very regularly arranged in three rows of 2 round yellow spots and at the apical end there is a spot like that of H. natalensis. Punctuation, pubescence and femoral lines as in H. natalensis. Claw tooth small and rounded. [...]

Quite rare earwig species, endemic to Cape, South Africa (other species of Esphalmenus genus known from South Africa and Andes region of South America only according to Steinmann 1989).
Originally described as Gonolabis peringueyi by de Bormans in 1900. Type and syntypes were collected from Caledon, Cape Colony.
Type stored in NHM, London, UK (no pictures available):

Key to differentiate from other Esphalmenus species in South Africa (based on adult males only):

1. Black species; forceps without a dorsal process at the base of each branch, and branches less strongly curved; penultimate sternite
   not excised apically. . . .ecarinatus

2. Reddish-brown or dark reddish-brown species; forceps with a dorsal process at the base of each branch of the forceps, and branches strongly curved; penultimate sternite excised apically. . . .3
3. Abdomen very strongly widened posteriorly, ninth tergite nearly twice as wide as second; each branch of forceps with a large dorsal process at base. . . . capensis
4. Abdomen less strongly widened posteriorly; each branch of forceps with a small dorsal process at base . . . . peringueyi

Head yellowish. Antennse entirely yellowish except for the last segment, which is black; all flagellar segments unusually short, the last two not longer than the others, terminal segment (thirteenth) somewhat stouter and more pubescent; verticils shorter than usual, the whole antenna resembling that of the Chironomid genus Tanypus. Palpi mainly dark brown, but second segment largely yellowish. Thorax pale whitish yellow; pronotal lobes dark brown; four brownish-yellow stripes on scutum. Abdomen yellowish. Legs whitish; femora and tibise without dark rings, even at the tip, but with numerous minute brown dots at the bases of the hairs; tarsi with tips of segments darkened. Wings whitish, with small black dots at the bases of the three forks, at the base of Rs, over the cros-veins, and at tips of all veins except R1 and R3. A small adventitious cross-vein (covered by a black dot) connects R1 with the costa near its tip, the actual tip of Rx being faint. Rs longer than in most species of this subgenus, with short spur at basal angle. Cell R, less than twice as long as its stem, its base level with or slightly beyond that of cell M1. M2 angled and slightly spurred at the base. Spur of Cu2 shorter than in most species of the subgenus.. Halteres chalk-white. Wing-length 3,5 mm.

Translated from French:
Subhemispherical. Prothorax flavous, adorned with a basal border with five teeth, the medial of which forms the foot of an almost cup-shaped spot, black. Elytra decorated with a sutural border, and a marginal and each with a longitudinal black band: the latter without curvature at its base, extended up to three-quarters; adorned on each side of it with a testaceous-red band on a yellow background. Black belly. Femora partly black.

Differential diagnosis by Fürsch:
https://www.zobodat.at/pdf/MittMuenchEntGes_077_0005-0031.pdf
Smaller than D. uncifera and D. olivieri, broadly oval. The black elytral stripe is bordered on both sides with yellow and then red stripes. This black longitudinal stripe reaches the base of the elytra. Reticulation and punctuation on pronotum and elytra clearly pronounced.
