Erymanthus flavonotatus Pic, 1932

( Figs 16–17 , 39 E)

Pic 1932: 5; Pic 1933: 116; Pic 1950: 160.

Specimen examined: Lectotype (designated here): Mayumbe, Cabra, Musée du Congo Belge, (MRAC). Comment on type specimen: Pic (1932: 5) does not mention the number of specimens, the specimen of Cabra is therefore considered a syntype ICZN 1999: Article 73.2) and available for lectotype designation (ICZN 1999: Article 74.1).

Diagnosis: Erymanthus flavonotatus can be confused with E. belzebuth , E. variolatus , and E. maculaticeps . Erymanthus maculaticeps has the abdomen dark brown to black. Erymanthus belzebuth and E. variolatus have dark markings basally and around the middle of femora.

Length: (1 specimen measured) 10mm.

Head: Light brown; frontal umbo with two grooves and posterior extension; with anteriorly directed flavous pilosity.

Pronotum: Pronotal length to width ratio 1.05:1; light brown; gibbosities and pronotal groove inconspicuous; with dense fine punctation; with isolated flavous pilosity.

Scutellum: Black; vested with white setae.

Elytra: Elytral length to width ratio 2.01:1; lighter brown than head and pronotum, one black spot on each side in anterior half; punctation circular, coarse, first 2–4 rows slightly rasp-like, interstices half as wide as diameter of punctation, irregularly distributed; with isolated flavous pilosity; all gibbosities with white setal tuft, E not distinct, with dense fine punctation.

Legs: Light brown, tibiae darker; indication of dark spot on pro- and mesofemora, metafemora basally towards middle dark; coxae except for procoxae (with light spot) dark.

Lower surface: Dark brown to black, last two abdominal segments light brown, other abdominal segments with light spot laterally; meso- and metathorax with dense white pilosity.

Male genitalia, pygidium, ventrite VI: Tips of tegminal lobes pointed, tegminal lobes very short; tegminal struts broadened until three-sevenths length and tapering lanceolate until tip; phallic tip hooklike in lateral view; posterior side of pygidium rather angular; processes of ventrite VI pointed.

Distribution: DR Congo.

Seasonal occurrence: Not specified.
