1. SCORE THIS FIRST - Subgenus

12Apis - These are Apis which nest in cavities when possible, where they build multiple combs - They are mid-sized, USUALLY averaging somewhere around 10-13mm in length and with a forewing length of 7-10mm in the worker according to Engel, 1999 - Due to human use, this subgenus is found practically worldwide although some of the species have much more restricted distributions - Distal abscissa of vein M in hind wing is variable, either present or absent    8Megapis - These are Apis which nest openly without shelter, building only a single comb in doing so - They are very large, USUALLY about 15mm or greater in length and with a forewing length of 12-15mm in the worker according to Engel, 1999 - The single species of this subgenus is found throughout much of the Pacific Islands north into Southeast Asia and west through Southern Asia and limited parts of Southern China, reaching at least as far west as Pakistan - Distal abscissa of vein M present in both sexes, meaning the closed cell which reaches farthest apically in the hind wing has TWO distinct veins coming off its tip    4Micrapis - These are Apis which nest openly without shelter, building only a single comb in doing so - They are very small, ALMOST ALWAYS averaging below 10mm in length and with a forewing length of 6-7mm in the worker according to Engel, 1999 - The two species of this subgenus are found throughout much of the Pacific Islands and more recently parts of Australia, ranging upward into Southwest and Eastern Asia as far north as Southern Russia, west through much of China at least as far as the Arabian Peninsula - The male drones may be easily differentiated from other subgenera by the presence of a thumb-like process arising from the base of the hind basitarsus - Distal abscissa of vein M absent in both sexes, if appearing present then with only ONE vein extending off the farthest apically projecting cell
