REFINEMENT OF THE RATIO OF THE ELYTRAL SUTURE LENGTH TO THE PRONOTUM LENGTH AS A CHARACTER FOR DIFFERENTIATION OF SUBGENERA OF THE CARPOPHILUS STEPHENS GENUS, 1830 (INSECTA: COLEOPTERA: NITIDULIDAE)
The ratio of the elytral suture length to the pronotum length of the adults’ genus Carpophilus Stephens, 1830 are presented in the article. This was determined by metric measurements from the dorsal projection photographs of the sap beetles’ species in Russia and other species of various subgenus. The sap beetles’ species of subgenera C. (Carpophilus), C. (Myothorax), C. (Semocarpolus), C. (Megacarpolus) and C. (Ecnomorphus) have the ratio in the range of 0.800-1,633 was found. The sap beetles’ species of hemipterus-subgroup of subgenera C. (Carpophilus) are characterized the ratio of up to 0.950 was found. The sap beetles’ species of subgenera C. (Myothorax), C. (Semocarpolus) u C. (Megacarpolus) have cross values of the ratio in the range of 1.000-1.350 was found. Subgenera C. (Ecnomorphus) is characterized the ratio of over 1.350 was found.
