Fig. 128

Notes

Only one female (DEI-GISHym84691) known. 5.4 mm. Nuclear data suggests that it is different from all the other sampled species. Externally most similar to E. leptostigma , E. leucopyga , E. parviserrata , E. polaris , E. sordidiapex , and E. sulciceps . Of these, E. polaris has the most similar lancet, but DEIGISHym84691 may have somewhat longer and flatter serrulae. DEI-GISHym84691 has also a slightly matt mesepisternum which is smooth in E. polaris . A similar lancet is also found in E. poppii , which can be almost as dark as DEI-GISHym84691, but E. poppii seems to be (usually?) smaller (<5 mm) and has a smooth mesepisternum.

Host plants

Unknown.
