(Figs. 2F, 18–19)
Heriades leavitti Crawford, 1913. Some bees from the New Brunswick, with descriptions of a new species of Heriades. The Canadian Entomologist:270. Type locality: Nerepis, New Brunswick. Type in USNM.
Heriades crawfordi Graenicher, 1928:281.
Neotrypetes truncates Robertson, 1929:131.
Diagnosis. T3 with punctation medium-sized (0.7 times DOP as on scutum), and sparse punctures (1 time DOP) (Fig. 3J); tergal fasciae with rows of thin, white hairs (Fig. 3L); wings usually dusky. Male: large ocelli (Fig. 3C); posterior side of malar area rounded, not produced to angle; posterior margin of S5 with two rectangular lobes, with two rounded tufts of capitate hairs directed inward, and simple short hairs directed outward, with transverse subapical line (Fig. 19E); S6 with posterior margin produced to right-angled apex, without blackish subapical margin, with two tufts of simple, short, thin hairs, directed downward (Fig. 19F). Female: apical margin of clypeus with two tubercles sided by others smaller and irregular shaped (Fig. 19C), similar to H. variolosa and H. cristina sp. nov., but different from first by having usually darker wings and by second for apical margin of clypeus straight, without emargination but with depression between tubercles and T3 with smaller punctation and dull integument.

Distribution. This species is mainly present in the United States and Canada; however, we found records that extend the distribution to Mexico, along the Gulf of Mexico slope and Yucatán Peninsula. The records of Quintos-Andrade, et al. (2023) of H. variolosa from Mexico, Veracruz, Coatepec and Xalapa belongs to H. leavitti. These areas correspond to the Sierra Madre Oriental, Veracruzan and Yucatán Peninsula biogeographic provinces (Morrone et al. 2022) (Fig. 18). The altitudinal range is from sea level to 1200 m.
Comments. This species is similar to H. variolosa; females of H. leavitti can be recognized by having greater DBP on scutum and dusky wings; and males can be easily recognized by having two tufts of simple, thin, short hairs on S6, not a few simple, scattered capitate hairs, and two rounded tufts of capitate hairs on S5, not one line.
