Heriades (Neotrypetes) micheneri Timberlake, 1947. Two new species of bees from Arizona (Hymenoptera, Apoidea). The PanPacific Entomologist. Vol. XXIII. No. 1:26.
Type locality: Patagonia, Arizona, on damp sand, August 8, 1940 (Timberlake).
Holotype female: UCRC.
Diagnosis. Small-sized bees (males 5.5–5.8 mm, n=5; females 5.6–6.1 mm, n=3), ocelli medium-size (Fig. 3B); punctation large along the whole body (Fig. 3F); dorsolateral angles of pronotum with tuft of plumose, short, whitish to yellowish hairs; tergal fasciae with row of thick, whitish hairs (Fig. 25C, D); body with plumose hairs in well-defined tufts; frons, disc of scutum, mesepisternum and terga with bare areas. Male: outer surface of mandible without tubercles; clypeus covered by plumose, long, white hairs directed medially (Fig. 25A); hypostomal area with plumose, long, white hairs, length surpassing mandible; S1 with strong ventral process, in profile when sides of process projected forming a right angle (Fig. 2 Aa), in posterior view with top semi circled (Fig. 2 Ac); S5 with two quadrangular lobes with acute strong angles on sides, and a few lines of simple, short thick hairs, increasing length outwards, with one transverse line of capitate hairs increasing in length outwards (Fig. 25E); S6 with two tufts of simple, short, thin hairs, directed downward, all hairs the same length (Fig. 25F). Female: similar to male, but without plumose hairs on clypeus (Fig. 25C), this species is similar to H. danuncia sp. nov (Fig. 23B, D).

Distribution. This species is present in the states of Arizona and New Mexico in the United States, and in Mexico in the states of Chihuahua, Sonora and northern Sinaloa, mostly in xeric areas of the Sonoran, Sierra Madre Occidental and Chihuahuan biogeographic provinces (Morrone et al. 2022). Altitudinal range: sea level to 1426 m (Fig. 24).
Comments. The size of ocelli varies but seems to be always bigger than the surrounding punctures on the vertex. The color on tufts of dorsolateral angles of pronotum and others varies from a yellowish white to orange but more frequently they are orange on H amanda sp. nov.
