T. concavus vs. T. remigatus
 T. concavus - Thorax, scutum, the entire anterior border of the scutum is covered in small prone white hairs, lacks band of black integument like T. remigatus - In direct comparison LARGER - Nest parasite of Svastra (1)
 T. remigatus - Thorax, scutum, with stripe of black integument that runs up the center to anterior edge, bordered by prone white hairs, the shape of the overall black portions of the integument on the scutum is anchor-shaped - In direct comparison SMALLER - Nest parasite of Peponapis, Xenoglossa, possibly Dieunomia (1)
T. concavus vs. all
 All - Abdomen, pseudopygidial area, type of hair, mostly APPRESSED OR SUBERECT (22)
 T. concavus - Abdomen, pseudopygidial area, type of hair, RANGES from SHORT near apical rim TO LONG towards the base of the pseudopygidium, all hairs slanting up and back towards the tip forming an unique 3-dimensional structure that, looking from the rear, looks like a slanting slope of densely packed pin heads or the REAR-END OF A PORCUPINE (1)
T. cressonii vs. T. helianthi vs. T. monardae
 T. cressonii - Abdomen, T5, hairs lateral to the pseudopygidial area are white and allow roughly 50 percent of the integument to show between them - Thorax, mesepisturnum, upper portion, with a SMALL PATCH to thin stripe of white appressed hairs near its rear suture that doesn t always reach the pronotal lobe - In direct comparison, smaller (1)
 T. helianthi - Abdomen, T5, regiona lateral to the pseudopygidial area covered in light hairs usually with a slight yellowish tinge, these hairs so dense as to completely obscure the integument - Thorax, mesepisturnum, upper portion, with a strong WIDE BAND of white appressed hairs running from the pronotal lobe to the rear suture (1)
 T. monardae - Thorax, mesepisturnum, upper portion, ENTIRELY COVERED with white appressed hairs (1)
T. helianthi vs. T. micropygius
 T. helianthi - Thorax, mesepisturnum, amount and pattern of hair, upper half with a TRANSVERSE BAND of matted, short, thick, white appressed hairs, and lower half with such hairs absent or with only a FEW HAIRS near the edges of the segment - Compartively, not as hairy as T. micropygius (1)
 T. micropygius - Thorax, mesepisturnum, amount and pattern of hair, integument of the upper half almost ENTIRELY HIDDEN by a dense mat of short, thick appressed white hairs, and the lower half with a lower density of similar white hairs through in which the integument is visible - Comparitively, hairier than T. helianthi (1)
T. mitchelli vs. all
 All - DEFAULT option - Species for which the female is KNOWN, always choose this option first (23)
 T. mitchelli - Species for which the female is currently UNKNOWN (1)
T. quadrifasciatus atlanticus vs. all
 All - Thorax, pronotal collar, length at midpoint, NORMAL, about one lateral ocellar diameter in length (23)
 T. quadrifasciatus - Thorax, pronotal collar, length at midpoint, LONG, about 1.5 - 2 lateral ocellar diameters in length - Note - T. concavus also may have a collar of the same length (2)
Thorax, integument color of scutellum
 Entirely black to dark brown (23)
 Black to dark brown with some red, orange, or amber (3)
 Entirely and distinctly red, orange, or amber (2)
Thorax, lower half of mesepisternum, appearance of integument between pits - Caution, see explain
 Flat or nearly so (19)
 Raised, rough, as if covered with rounded, projecting lobes (17)
 Not applicable - Hair in this area exceptionally dense obscuring view of surface (2)
Thorax, mesepisternum lateral -not ventral- surface, length of erect simple hairs - Caution, see explain
 LACKING hairs of this type (17)
 Length LESS than 0.5 lateral ocellar diameter (13)
 Length GREATER than 1 lateral ocellar diameter (5)
Thorax, primary integument color of pronotal lobe
 Black to dark brown (21)
 Red, orange, or amber (10)
Thorax, primary integument color of tegula
 Black to dark brown (19)
 Red, orange, or amber (14)
Thorax, scutum, PRESENCE or ABSENCE of a PAIR of distinct NARROW STRIPS OF PALE HAIR running longitudinally from the anterior margin of the scutum

 Indistinct, NOT distinguishable from pale hair on apical half of scutum (3)
