Diagnosis of Coccinella transversoguttata species group

Species of Coccinella with body ovoid, usually acuminate at apex, medium- to large-sized, slightly to moderately convex. Ground colour of elytra red, black pattern composed of 11 spots arranged in a pattern of ½, 1, 1, 1 and 2. Elytral suture sometimes bordered with black stripe, transversal (½ +1, 2+3, 4+5) and/or longitudinal (1+2) fusions of spots frequent and species-specific. Pale markings of fore legs always present in male. Apices of hind femora reaching or usually surpassing outer margin of epipleura. Median lobe of aedeagus composed of two portions: basal portion simply rectangular; distal portion, arising dorsally from the basal one, hastate and specific, at base always less than half as wide as basal portion. Basal piece of aedeagus quadrangular, truncate distally, and bearing large triangular appendix. Sipho with large elongate siphonal capsule, armed with strong inner hook-shaped branch, outer rib large, nearly semicircular. Basal portion of siphonal tube not dilated laterally. Preapical portion of sipho moderately enlarged, bearing at least two inequal membranose swellings. Spermatheca densely annulate, infundibulum large but slender, equally dilated at both ends.
