Colemanus contortus (Brues, 1933) comb. n.

Remarks.

Two other fossil ichneutines have been described, both from Baltic amber of the lower Oligocene ( Brues 1933): Ichneutes stigmaticus and I. contortus . The illustration of I. stigmaticus ( Brues 1933: pl. 10 fig. 58) is not similar to Colemanus . However, the description for I. contortus ( Brues 1933: pg. 89-90; pl. 10 fig. 50) is consistent with Colemanus in having "coarsely crenulated" notauli (pg. 90) and a fore wing (pl. 10 fig. 50) with recurved 3RSb and nearly vertical (RS+M)b. Further, fore wing 3RSb appears to be tubular as it reaches the wing margin (unlike Cardiochilinae ); a carapace is absent (unlike Cheloninae ); and 1M is evenly curved (consistent with Proteropini ). Therefore, we suggest the new combination Colemanus contortus (Brues, 1933).

The material Brues (1933) examined is part of the Königsberg collection. Most of this collection was rescued and is housed at the Geowissenschaftliches Museum ( Göttingen, Germany), though some of Brues's collection, which included some of the Königsberg collection, remains at Harvard University, his old institution. However, neither the Museum of Comparative Anatomy (Harvard), nor the Geowissenschaftliches Museum could locate Brues's 1933 material, including Ichneutes contortus . The problem is exacerbated by the fact that Brues did not include catalog numbers in his description or any other information regarding deposition. Therefore, the holotype of I. contortus should be considered lost.
