The ‘ red-tailed’ Lasioglossum (Dialictus) (Hymenoptera: Halictidae) of the western Nearctic
Fig. 1. Colour variation in the metasoma of Lasioglossum (D.) hudsoniellum (Cockerell, 1919). A. Yellow-orange. B. Red-orange. C. Reddish brown. D. Black. “Red-tailed” Lasioglossum (Dialictus) are considered to be any species with natural colour matching A or B.
Fig. 42. Georeferenced collection records of Lasioglossum (D.) hudsoniellum (Cockerell, 1919) (black squares) and predicted distribution by maximum entropy ecological niche modeling in Maxent (colour shading). Warmer colours indicate higher cloglog probability of occurrence.
Fig. 90. Male genitalia. A. Lasioglossum (D.) arenisaltans sp. nov. B. L. (D.) clastipedion sp. nov. C. L. (D.) clematisellum (Cockerell, 1904). D. L. (D.) hudsoniellum (Cockerell, 1919). E. L. (D.) julipile sp. nov. F. L. (D.) lilianae sp. nov. G. L. (D.) mesillense (Cockerell, 1898). H. L. (D.) meteorum sp. nov. I. L. (D.) miltolepoides sp. nov. J. L. (D.) minckleyi sp. nov. K. L. (D.) pallidellum (Ellis, 1914). L. L. (D.) pictum (Crawford, 1902). M. L. (D.) rufornatum sp. nov. N. L. (D.) spivakae sp. nov. O. L. (D.) testaceum (Robertson, 1897).P. L. (D.) vierecki (Crawford, 1904). Q. L. (D.) zephyrus (Smith, 1853). Genitalia are illustrated in dorsal view and positioned such that the gonostylus is parallel to the plane of vision. Retrorse lobes are also illustrated separately to the bottom left of each figure in lateral view, positioned parallel to the plane of vision.
Fig. 107. Pronotal angle (arrow and outline). A. Lasioglossum (D.) hudsoniellum (Cockerell, 1919), ♀, nearly 90 degrees. B. L. (D.) minckleyi sp. nov., ♀, obtuse. Scale bars: 0.5 mm.
Fig. 116. Metasomal sterna, ♂. A. Lasioglossum (D.) zephyrus (Smith, 1853), with hair concentrated in apicolateral areas of S3–5. B. Typical red-tailed Lasioglossum (Dialictus), with hair evenly distributed and S5 straight. C. L. (D.) hudsoniellum (Cockerell, 1919), with S5 concave.
