Comments on identification. Seriously damaged piece of amber (broken into 5 small pieces), one of which contains the posterior half of the body of the holotype. A dark and thin dorso-lateral ridge is clearly visible on the left metatibia along its entire length, which is identical to that in Baltimorda ?undescribed species A. Metatarsal segments are not visible and likely absent. Because of the presence of the dorso-lateral ridge, this species cannot be attributed to Mordella and is transferred here to Baltimorda new collective group.
