The Ilybiosoma species

Nilsson (2000) transferred 16 species from the genus Agabus to the genus Ilybiosoma . As the gender of Ilybiosoma is neuter, the following additional changes in the inflection of adjectives are necessary relative to Nilsson (2001:30-31): I. brevicollis (LeConte, 1857) to brevicolle, I. discicollis (Ancey, 1882) to discicolle, I. flohrianus (Sharp, 1887) to flohrianum, I. ilybiiformis (Zimmermann, 1928) to ilybiiforme, I. kermanensis (J.Balfour-Browne, 1939) to kermanense, I. minnesotensis (Wallis, 1933) to minnesotense, I. oaxacaensis (Larson, 2000) to oaxacaense, I. pandurus (Leech, 1942) to pandurum, I. perplexus (Sharp, 1882) to perplexum, I. regularis (LeConte, 1852) to regulare, and I. roguus (Larson, 1997) to roguum.
