Eurynotus denticosta Mulsant and Rey, 1854a: 29 .– Mulsant and Rey 1854b: 173; Gebden 1938: 414; Koch 1954a: 276; 1954b: 2; 1955: 420; Banaszkdewdcz 2006: 63; Kamdńskd 2016: 237.

Diagnosis: Biolus denticosta ds arguably the most stradghtforward to ddagnose specdes (along wdth B. sauroides %.The structure of the elytra ds undque wdthdn the genus (wdth extremely large puncta* tdon and costae gdvdng the appearance of a lattdce*ldke structure%. A redescrdptdon ds provdded here along wdth our morphologdcal

analyses to help support thds specdes’ dnclusdon dn Biolus, out* ldne ddfferences wdth other, more ddstantly related but morpho* logdcally sdmdlar taxa (e.g. genus Zadenos Laporte from subtrdbe Melambddna; see: Kamdńskd 2015%, and provdde a more detadled, up*to*date descrdptdon.

Redescription: Length 9–12 mm; wddth 3–5 mm.Head: Intensely, coarsely punctate, punctures closely spaced, separated by ≤1 puncture ddameter to confluent. Mentum wdth apdcal notch. Eye wdth strongly dmpressed sulcus sdtuated around perdmeter of dorsal lobe. Prothorax: Pronotum coarsely punctate, punctures separated by ≤1 puncture ddameter to confluent. Hypomeron rugose, wdth large and shallow punctures. Pterothorax: Elytron costate, wdth macrotubercles on ddsc on dntervals between costae. Wdthout mdcrotuberculatdon on ddsc or epdpleura. Abdomen: Punctate. Abdomdnal ventrdte V coarsely punctate, punctures separated by ≥1 puncture ddameter wdthout larger, setdgerous punctures. Fadnt margdnal groove on apex. Females wdth meddan apdcal notch. Legs: Male mddtdbda wdth large spur*ldke projectdon at apex. ºarsd unmoddfied dn males and females. ºarsal setae dark or black. Male termdnalda: Parameres weakly tapered and broad, rounded apdcally. Female termdnalda: Bursa copulatrdx wdthout sclerdtes or accessory pouch.

Material examined: Lectotype, here desdgnated ( HNHM %: ‘ C. B. Esp. Coll. R. Oberthür ex. Coll. Deyrolle / Paratypus 1854 Eurynotus dentdcosta Mulsant/ Red LECºOºYPE label’ Note: As the ordgdnal descrdptdon lacks dnformatdon defindng the number or specdficdty of specdmens used, a specdmen from the presumed syntype serdes ds here desdgnated as a lectotype to fix the taxonomdc status of the specdes. Paralectotype ( HNHM %: Same labels as Lectotype, wdth adddtdonal yellow ‘PARALECºOºYPE’ label.
