description
Saether (1977 a: 87) mentions that several species of the Cryptochironomus fulvus agglomerate until now have not been separable as imagines. However, their pupae are quite distinct. One new species and a variety, which may be an additional species, are described below. In addition, drawings of Cryptochironomus ponderosus (Sublette) and a pupa of C. eminentia Mason are given. Sublette (1964: 131) redefines C. fulvus (Johannsen) and takes Chironomus sp. C of Malloch (1915: 529) to represent the pupa. However, Sublette (1964: 132) states that the frontal tubercles in all his material are distinct while Townes (1945: 99) states that the frontal tubercles are absent or perhaps sometimes present and very small. As it will appear from the key to male imagines, the frontal tubercles are a specific character usually, and Townes' material must have contained more than one species. It is quite likely that one or two species will fall as a synonym of Cryptochironomus mallochi (Kieffer) (Kieffer 1919: 191), new name for C. abbreviatus (Malloch) (Malloch 1915: 451) or Cryptochironomus parvilamellatus (Malloch) (Malloch 1915: 479).
