Dear forumists,

We in Finland have some problems in determining male specimens of Ischiolepta (Sphaeroceridae) somewhere around the species crenata/micropyga. The pictures of male genitals of these species aren't illustrated in the British monograph, only some other species of this genus are included.

Does anyone know any article where there are pictures of male genitals of these two Ischioleptas?

Also other comments on differentiating these two ones are gratefully welcomed,
