Revision of the Nearctic species of the Lasioglossum (Dialictus) gemmatum species complex (Hymenoptera: Halictidae)
Fig. 83. Mesonotum. A. Lasioglossum gloriosum sp. nov., ♀, with dense tomentum on metanotum and margins of mesoscutum. B. L. tegulare (Robertson, 1890), ♀, with sparse tomentum. Scale bars = 0.5 mm.
Fig. 85. Metasomal terga. A. Lasioglossum coactus (Cresson, 1872), ♀, with T2–T3 each slightly convex and apical rim downcurved in lateral view.B. L. tegulare (Robertson, 1890), ♀, with T2–T3 each flat and apical rim continuous with contour of disc in lateral view. Scale bars = 0.5 mm.
Fig. 98. Mesepisternum. A. Lasioglossum diabolicum sp. nov., ♀, shiny with distinct round punctures. B. L. tegulare (Robertson, 1890), ♀, dull and rugulose. Scale bars = 0.5 mm.
Fig. 101. Face. A. Lasioglossum puteulanum Gibbs, 2009, ♀, slightly longer. B. L. tegulare (Robertson, 1890), ♀, slightly shorter. Scale bars = 1 mm.
Fig. 118. Face. A. Lasioglossum puteulanum Gibbs, 2009, ♂, slightly longer. B. L. tegulare (Robertson, 1890), ♂, slightly shorter. Scale bars = 1 mm.
Fig. 117. T2. A. Lasioglossum egulare (Robertson, 1890), ♂, with dense punctures up to premarginal line sharply contrasting with impunctate apical rim. B. L. diabolicum sp. nov., ♂, with punctures becoming more sparsely punctate near and on premarginal line and not sharply contrasting with apical rim. Scale bars = 0.5 mm.
