Sleeping Chironomid

Note on citation 1: Hinton (1960a) states that P. vanderplanki is found in arid regions of northern Nigeria and Uganda, which is surprising, since the two countries are far apart and Uganda has few arid regions. I consulted gbif (gbif.org, accessed 5/22/19), a global database for species occurrence records. There are only two records for P. vanderplanki; the holotype specimen (a specimen stored in a museum to represent the taxa (species, genus, family etc.) so researchers can compare any organisms they’ve found that they think might be undescribed) stored in the British Natural History Museum, originally found in Nigeria, and another specimen from the Institute of Research and Development in France, found in Burkina Faso, a country much more arid and closer to Nigeria than Uganda. I could not find any other sources stating that the midge was found in Uganda which did not cite Hinton’s paper, and so have decided to use those two occurrences.
