7. Biolus omeri (Koch) comb. nov.

(Figs 2G, 5C, 7B, 8G)

Eurynotus ( Biolus) omeri Koch 1954a: 277 .– Kamiński 2016: 235.

Diagnosis: Like B. granulatus, separating this species from others with similar characteristics is best done through a suite of characters. Biolus omeri is most similar to B. granulatus . In fact, specimens identified in the past as the here synonymized Eurynotus ( Biolus) norrisi are at first glance difficult to differ - entiate. The most glaring differences and distinctive traits of B. omeri are the tarsal setae (black), the sharp well -defined tuber - culation of the elytra, and lack of additional puncture types on abdominal ventrite V. See diagnoses of other species for add - itional details.

Redescription: Length 14–18 mm; width 8–9 mm. Head: Coarsely punctate, punctures closely spaced, separated by ≤1 puncture diameter to confluent. Mentum with apical notch. Eye with impressed sulcus around margin. Prothorax: Pronotum coarsely punctate, punctures separated by ≤1 punc - ture diameter to confluent. Hypomeron rugose, with large and shallow punctures. Pterothorax: Elytron not costate, with macrotubercles on disc. Microtubercles absent from elytral

disc and epipleura. Abdomen: Punctate. Abdominal ventrite V punctures separated by ≥1 puncture diameter without larger, setigerous punctures intermixed. Females without median ap - ical notch. Legs: Male and Female legs unmodified. Tarsi with black setae. Males: Pro/meso tarsi robust with large, ventral, tomentose pads. Male terminalia: Parameres weakly tapering with tips sharply tapering and directed medially. Female terminalia: Bursa copulatrix without sclerites or accessory pouch.
