( Fig. 3J )

Eurynotus ( Biolus) thermarum Koch 1954a: 282 .– Koch 1955: 423; Kamiński 2016: 236.

Diagnosis: Similar to E. barbosai and E. graniderma , can be separ - ated from other species using size, microtuberculation, and male hind tibia structure (see respective diagnoses for separating this species from E. barbosai and E. graniderma ).

Redescription: Length 10–13.25 mm; width 5.25–7.5 mm. Head: Finely punctate, punctures closely spaced, separated by ≤1 puncture diameter. Mentum without apical notch. Eye with circumocular groove. Prothorax: Pronotum finely punctate, punctures separated by ≥1 puncture diameter; interstices with microtubercles. Hypomeron shallowly and finely punctate and lightly sculptured/wrinkled. Pterothorax: Elytral interval X terminating between hind coxae and elytral base. Elytra with microtubercles. Epipleuron narrower than width of elytral inter - vals 9 + 10. Elytral intervals not obscured by epipleuron in ventral view. Abdomen: Punctate. Abdominal ventrite V finely punctate, punctures separated by ≥1 puncture diameter without larger, setigerous punctures intermixed. Females without me - dian apical notch. Legs: Tarsi with black or dark setae. Female terminalia: Bursa copulatrix sac -like and without sclerites, spermatheca thick and coiled, accessory pouch present.
