03C987C8FFA6FFAFFF1CFC57FD0CFA62.taxon	diagnosis	Diagnosis. Members of the L. tegulare group can be distinguished from most other Dialictus by the presence of an enlarged and punctate tegula. In North America, there are two exceptions; L. marinum and L. megastictum (Cockerell) both have enlarged tegula but additional morphological data do not support a close relationship to L. tegulare (Gibbs, unpublished data). Both of these latter species are larger than members of the tegulare group and have dense punctation on the mesoscutum. In contrast, species within the tegulare group are small to at most medium-sized Dialictus and have close but distinctly separated punctures on the central disc of the mesoscutum. In addition, L. marinum has metallic reflections on the metasoma that are absent in the tegulare group. Lasioglossum megastictum lacks punctures on the mesepisternum that are a common feature of many tegulare group species.	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

03C987C8FFA6FFB2FF1CF99DFCA2F909.taxon	diagnosis	Diagnosis. Females of L. tegulare can be recognized by the following combination of characters: head and mesosoma pale to golden green, paraocular area with sparse, subappressed hairs which do not obscure the surface, distinct microsculpture between punctures of mesoscutum and mesepisternum, and three or four teeth on the inner hind tibial spur (not including apex of rachis). Females of L. puteulanum have the head and mesosoma deep blue. Females of L. lepidii have dense subappressed hairs on the paraocular area which obscure the surface adjacent to the inner eye margin and lower paraocular area. Females of L. ellisiae have the integument of the mesoscutum (particularly adjacent to parapsidal lines) and mesepisternum smooth, with at most faint microsculpture which gives these areas a shiny appearance. Females of L. carlinvillense have only two teeth on the inner hind tibial spur. Males of L. tegulare can be recognized by the following combination of characters: ventral surface of flagellum pale, appressed hairs of face mostly limited to paraocular areas and not obscuring clypeus, and T 2 – T 3 punctures uniformly dense on disc basal to the premarginal line. Males of L. ellisiae have the ventral surface of the flagellum dark to ferruginous and T 2 – T 3 punctures dense on basal half but sparse approaching premarginal line. Males of L. lepidii have the ventral surface of the flagellum bright yellow and appressed hairs of the face dense, obscuring the majority of the clypeus. Males of L. puteulanum have appressed hairs more uniformly distributed on face with less than half of the clypeal surface obscured. Redescription. Female. Length: 4.7 (4.0 – 4.9) mm, fore wing length: 3.3 (2.8 – 3.5) mm head width: 1.4 (1.2 – 1.4) mm, head length: 1.3 (1.1 – 1.3) mm, n = 20	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

03C987C8FFA6FFB2FF1CF99DFCA2F909.taxon	discussion	Comments. The range of L. tegulare is evidently more restricted than previously reported (Moure & Hurd 1987). Northwestern and southeastern records likely correspond to one or other of the species described below. Some records from Texas could be misidentifications of L. coactum (Cresson), which differs in having deeply impressed marginal zones of T 1 and T 2 in both sexes.	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

03C987C8FFBBFFB6FF1CF925FE04FCF5.taxon	diagnosis	Diagnosis. Females of L. ellisiae are unique in having the integument of the mesoscutum (especially adjacent to the parapsidal lines) and mesepisternum smoother and more reflective than those of other species of the tegulare group in eastern North America. The remaining four species each have the integument in these areas roughened and dulled due to microsculpture. Females of L. ellisiae can be further distinguished by the following characters: head and mesosoma primarily bluish-green, paraocular area with sparse subappressed hairs, and inner hind tibial spur with 3 or 4 teeth (not including apex of rachis). Females of L. puteulanum are deep blue in colour. Females of L. lepidii have dense subappressed hairs on the paraocular area which obscure the surface adjacent to the inner eye margin and lower paraocular area. Females of L. carlinvillense have only 2 teeth on the inner hind tibial spur. Males of L. ellisiae can be distinguished from the other species by the sparsely punctate zones of T 2 and T 3 anterior of the premarginal line. The males of L. tegulare, L. lepidii, and L. puteulanum all have uniformly dense punctation basal to the premarginal lines of T 2 and T 3. Redescription. Female. Length: 5.25 (4.6 – 5.5) mm, fore wing length: 3.5 (3.1 – 3.7) mm, head length: 1.3 (1.1 – 1.4) mm, head width: 1.4 (1.2 – 1.4) mm, n = 9	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

03C987C8FFBBFFB6FF1CF925FE04FCF5.taxon	discussion	Comments. Specimens that could be attributed to this species extend its range into the great plains of the United States. Additional western species that could be mistaken for L. ellisiae may co-occur in this area. Further study will be needed to test species boundaries of the western fauna and to determine the western range limits of L. ellisiae.	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

03C987C8FFBFFFBBFF1CFC0EFC72FC83.taxon	diagnosis	Diagnosis. Females of L. lepidii can be distinguished by the following combination of characters: head and mesosoma pale to golden green, paraocular area partially obscured by appressed hairs along inner eye margin, distinct microsculpture between punctures of mesoscutum and mesepisternum, and three teeth on the inner hind tibial spur (not including apex of rachis). Females of L. puteulanum have the head and mesosoma deep blue. Females of L. tegulare have sparse subappressed hairs on the paraocular area which do not obscure the surface. Females of L. ellisiae have the integument of the mesoscutum (particularly adjacent to parapsidal lines) and mesepisternum smooth, with at most faint microsculpture which gives these areas a shiny appearance. Females of L. carlinvillense have only two teeth on the inner hind tibial spur. Males of L. lepidii are unique among these species in having dense, appressed hairs that obscure large areas of the face including the paraocular area, clypeus and frons. Males of other species have more limited tomentum on the face often only obscuring the paraocular area and never obscuring the frons. Redescription. Female. Length: 4.3 (4.3 – 4.9) mm, fore wing length: 3 (3.0 – 3.2) mm, head length: 1.3 mm, head width: 1.3 (1.3 – 1.4) mm, n = 2	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

Dr. Julio Genaro, the expert on Caribbean Apoidea, is unaware of any species matching the description of this species in the neighbouring islands (J. A. Genaro; personal communication).	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

03C987C8FFB2FFB8FF1CFCBCFB0DFC28.taxon	diagnosis	Diagnosis. Females of L. puteulanum are unique among these species in having the head and mesosoma distinctly blue, whereas other species are typically pale or golden green to at most faintly bluish-green. The head is on average slightly longer (often longer than wide) (ratio = 0.95: 1.10) and the clypeus protrudes giving the face a more triangular appearance than other species. In contrast, females of other species often have the head wider than long (ratio = 0.85: 1.0) with a much rounder appearance of the face. The males of L. puteulanum can be recognized by the following combination of characters: head and mesosoma blue, ventral surface of flagellum pale, appressed hairs of face mostly limited to paraocular areas and only partially obscuring clypeus, and T 2 – T 3 punctures uniformly dense on disc basal to the premarginal line. Males of L. ellisiae have the ventral surface of the flagellum dark to ferruginous and T 2 – T 3 punctures dense on basal half but sparse approaching premarginal line. Males of L. lepidii have the ventral surface of the flagellum bright yellow and appressed hairs of the face dense, obscuring the majority of the clypeus and frons. The subappressed hairs of the face of L. tegulare are usually limited to the lower paraocular area but are more evenly distributed across the face in L. puteulanum.	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).

The blue colouration characteristic of this species should be sufficient to identify most individuals; however, colouration is sometimes variable in Dialictus and can be affected by preservation methods. Species identification of questionable specimens is possible using DNA barcodes.	en	Gibbs, Jason (2009): Integrative taxonomy identifies new (and old) species in the Lasioglossum (Dialictus) tegulare (Robertson) species group (Hymenoptera, Halictidae).
