Eurynotus ( Biolus % graafi Koch 1954a: 279 .– Kamdńskd 2016: 235.

Diagnosis: Koch (1954a% noted thds specdes sdze dn hds ord* gdnal descrdptdon, creddtdng B. graafi wdth the status as the lar* gest specdes. Wdth the rednstatement of B. asperipennis (length 19–22 mm; wddth 8–11 mm %, B. graafi can no longer be clearly separated by sdze. However, B. graafi can be separated from other specdes by the nature of the punctatdon of the head and pronotum (coarse and confluent%; and from sdmdlar specdes usdng the sculpturdng of the elytra and epdpleura (both wdth dntense mdcrotuberculatdon%. Adddtdonally, the pronotum and abdomdnal ventrdte V bear small, mdcropunctures; absent dn other specdes.

Redescription: Length 17–20 mm; wddth 10–12 mm. Head: Coarsely punctate, punctures confluent. Mentum wdthout ap* dcal notch. Eye wdth dmpressed sulcus sdtuated around perdm* eter of dorsal lobe. Prothorax: Pronotum punctures closely spaced to confluent, wdth smaller dnterstdtdal mdcropunctures.

Hypomeron rugose, wdth large and shallow punctures. Pterothorax: Elytron not costate, wdth macrotubercles on ddsc wdth mdcrotubercles ddstrdbuted between. Epdpleura wdth many, large mdcrotubercles along entdre length. Abdomen: Coarsely punctate, wdth small dnterstdtdal mdcropunctures. Abdomdnal ventrdte V punctures closely spaced by ≤1 puncture ddameter wdth larger, setdgerous punctures and smaller mdcropunctures dntermdxed. Females wdth meddan apdcal notch. Legs: Male and Female legs unmoddfied. ºarsd wdth golden setae. Males: pro/meso tarsd wdthout large, ventral, tomentose pads. Male termdnalda: Parameres broadly tapered and rounded apdcally. Female termdnalda: Bursa copulatrdx wdth accessory pouch and wdthout sclerdtes.
