Remarks Maurice Pic described Poecilomorpha cribricollis using material that he deposited in the Royal Museum for Central Africa in Tervuren (Pic 1951: 41). He did not specify how many specimens he reviewed, nor did he indicate that there was more than one. The Megalopodidae section at the Royal Museum for Central Africa is well curated, and within this collection, there is only one specimen labeled as the holotype (Fig. 3I). Therefore, the designation of the holotype follows the recommendations outlined in Articles 72.4.1.1 and 73.1.2 of the International Code of Zoological Nomenclature.
