Subspecies of Lunaoeps holophaeus have been erected by Timmermann 

 (1954b) to cover the forms found on small waders. The Lunaceps complex 

 is difficult to characterize at species level because they show such 

 little plasticity of shape. Even the male genitalia, an important 

 taxonomic character in most other genera, are of the same type through- 

 out the entire genus.

 Type host: Limosa haemastioa (Linnaeus) — Hudsonian Godwit. 



Timmermann (1954b) erected the species group Limosa for those 

 Lunaceps found on various godwits. He stated that, "A definite judge- 

 ment of the validity and limitation of this species can hardly be ob- 

 tained before a greater number of specimens from L. lapponica and all 

 nearer related populations have been subjected to a mathematical test 

 of their variability." 



L. limosella paschalis is a small member of the Limosa group with 

 a much shorter head and a clypeus without a dorsal preantennal suture.
