Type material examined: Holotype: ♂ “ Burundi Ngozi ” ( ZFMK) . Paratypes: see Appendix S1.

Description: Body length: 10.3 mm, elytral length: 7.1 mm, maximum width: 4.6 mm. Angle between lateral margins of labroclypeus and ocular canthus indistinct; anterior margin of labroclypeus medially weakly sinuate; margins of labroclypeus strongly reflexed; smooth area in front of eyes twice as wide as long; ratio of eye diameter/interocular width: 0.7. Pronotum with dense and thick erect setae; unicoloured; basal margin of pronotum complete; larger punctures on pronotum very coarse. Hypomeron not carinate. Elytra with dark spots; erect dorsal pilosity on elytra dense (more than ten setae per interval); sutural interval in apical declivity of elytra flat and not delimited by a sharp carina; white, fine pilosity condensed to transverse patches; intervals punctate at least laterally; adpressed white pilosity long, 1/3 to 1/2 of width of elytral intervals; external apical elytral angle evenly convex. Mesosternal process short. Ratio of length of metepisternum/ metacoxa: 1/1.33. Metatibia, ratio of width/length: 1/4. Metatarsi dorsally smooth; first metatarsomere as long as subsequent one. Aedeagus: Fig. 2U – W View Figure 2 . Habitus: Fig. 2X View Figure 2 . Female genitalia: Fig. 5E View Figure 5 .

Diagnosis: Pleophylla burundiensis sp. nov. resembles P. pilosa in external shape; however, the punctures on the dorsal surface are denser and coarser, and the sutural interval is flat and not limited by a sharp carina in the apical declivity of the elytra. This new species is in genital shape similar to P. maculipennis ; however, the right paramere is basally tooth-like and extended, and the basal dorsal portion of the left paramere bears two small teeth.

Variation: Body length: 8.0 – 10.3 mm, elytral length: 6.5 – 7.1 mm, maximum width: 4.2 – 4.8 mm. Density of dark spot may vary slightly, but never completely without spots. Female: antennal club of female straight, composed of five antennomeres, as long as the remaining antennomeres combined; sixth antennomere very short, less than 1/5 of club length. Eyes smaller than in male: ratio of eye diameter/ interocular width: 0.52.

Etymology: The new species is named after its occurrence in Burundi.

Remarks: In a previous publication we referred to this species as ‘SpM-21’ (Ozg € ul-Siemund € & Ahrens, 2015).
