The subspecies " Megachile campanulae wilmingtoni " ( Mitchell ) is characterized by larger size, dark pubescence present on the 6th tergum, and darker wings with a brownish tinge.
32.
The 2 % percent of " S . grandis " that overlapped with " S . convallis " were determined by density of the punctation in colour of the first tergum against the second.
33.
The abdomen's 1st tergum is black; 2nd tergum yellow except for small basomedial triangular maculae; 3rd tergum is yellow, with indistinct dark medial vitta; 4th tergum is brownish black and light yellowish brown laterally.

The abdomen's 1st tergum is black; 2nd tergum yellow except for small basomedial triangular maculae; 3rd tergum is yellow, with indistinct dark medial vitta; 4th tergum is brownish black and light yellowish brown laterally.

The abdomen's 1st tergum is black; 2nd tergum yellow except for small basomedial triangular maculae; 3rd tergum is yellow, with indistinct dark medial vitta; 4th tergum is brownish black and light yellowish brown laterally.
37.
The upperside of its abdomen is a dark olive-green, with a darker dorsal line prominent on running down the midline, which widens into a roughly triangular pattern at the rear end of each segment ( tergum ).
38.
Mesally it articulates anteriorly ( f ) with the posterior end of the second axillary, and posteriorly ( b ) with the posterior wing process of the tergum ( PNP ), or with a small fourth axillary when the latter is present.
39.
In addition, two autapomorphies ( a differently shaped petiolar tergum and sternum, and the eyes at or close to the apex of the antennal scrobe ) separated " Tatuidris " from all other extant ant genera included in their study.
40.
Mesally, it articulates anteriorly ( f ) with the posterior end of the second axillary, and posteriorly ( b ) with the posterior wing process of the tergum ( PNP ), or with a small fourth axillary when the latter is present.
