Lasioglossum (Chilalictus) eremaean Walker, K. 1995. Revision of the Australian native bee subgenus Lasioglossum (Chilalictus) (Hymenoptera: Halictidae). Memoirs of the Museum of Victoria 55: 1–423 [115].
Type data: Holotype QM T-13855 ?, 30 km S Alice Springs NT [24º12'S 133º52'E].
Diagnosis. Most like L. metallicum. Both sexes head and propodeum black, mesoscutum metallic green/blue, metasoma black suffused with brown. Female with frons punctate, mouthparts with glossa moderately long, and hirsute, mesoscutum densely punctate, dorsal surface of propodeum ruguloso-striolate, not defined by carina, BP apically pointed, T1 with mesolateral hair bands, metasomal tomentum across T2-T4. Male with antennae moderately long (FL 2.34 x UID), AS4 equal to AS2+3, glossa moderately long and hirsute, T1 with mesolateral hair tufts, sternal vestiture sparse, forewings with 2nd r-m as strong as 1st r-m.
Remarks. This species is commonly collected throughout the arid and semi-arid areas of Australia. To minimise variation within the paratype series, only those specimens taken at the same time, in the areas surrounding the type locality, were chosen. (See Remarks on L. metallicum for discussion of metallic mesosomal colour).
