Lasioglossum (Dialictus) weemsi (Mitchell)

Dialictus weemsi Mitchell, 1960: 431 . Ƥ.

Holotype. Ƥ USA, North Carolina, Wake Co., 16.vi. 1955 on Melilotus officinalis (H.V. Weems, Jr.) ; [ FSCA]. Examined.

Taxonomy. Krombein, 1967: Lasioglossum (Dialictus) weemsi , p. 467 (catalogue); Dialictus weemsi , p. 1973 (catalogue); Moure & Hurd, 1987: Dialictus weemsi , p. 140 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) weemsi Ƥ, p. 355 (redescription, key).

Diagnosis. Female L. weemsi can be recognised by the shape of the clypeus, which has the distal margin beyond the preapical fimbriae extending laterally making it noticeably wider than the preapical margin ( Figs. 21 View FIGURE 21 B). The distal portion of the clypeus has a rectangular appearance as a result. They may be further distinguished by the following combination: head wide (length/width ratio = 0.93–0.96); mesoscutum weakly tessellate, punctures moderately dense between parapsidal lines (i= 1–2 d); mesepisternum rugulose; tegula pale; tibiae mostly brown; and T 1 acarinarial fan with dorsal opening. They are most similar to L. mitchelli and L. weemsi , both of which have a similarly shaped clypeus. Female L. mitchelli do not have a dorsal opening on the T 1 acarinarial fan (or the opening is very narrow). Female L. leviense have extensive pale colouration on legs and slightly narrower heads (length/width ratio = 0.95–0.97).
