Diagnosis. Female L. albipenne can be recognised by the following diagnostic combination: head and mesosoma bluish; wings white, pterostigma and venation pale yellow; hypostomal carinae parallel, unreflexed; mesoscutal punctures coarse, sparse between parapsidal lines (i=1�3d); mesepisternum coarsely reticulate-rugose; propodeum strongly carinate; T1 acarinarial fan large without dorsal opening; and metasomal terga brown with dense tomentum, distinctly punctures throughout. They are most similar to L. cressonii, L. disparile, and L. nymphaearum. Female L. cressonii have the head and mesosoma golden green, mesoscutal punctures relatively dense (i=1�1.5d) and wings faintly dusky. Female L. disparile have a distinct glabrate band on the declivitous surface of T1 separating the acarinarial fan from a dorsal hair band. Female L. nymphaearum have hypostomal carina reflexed distally and propodeal dorsal and posterior surfaces separated by uninterrupted transverse carina.

Male L. albipenne are similar to females except for the following: head elongate (length/width ratio = 0.99�1.08); face obscured by abundant white hairs; flagellomeres short (length/width ratio = 1.21�1.31), bright yellow ventrally; and mesepisternum punctate-reticulate. They are most similar to L. pruinosum and L. nymphaearum. Male L. pruinosum have the clypeus with distal yellow maculation. Male L. nymphaearum have tegula distinctly punctate.

DNA Barcode. Available. Multiple sequences.

Comments. Common.

Variation in the strength of the female propodeal carinae can be seen in long series. Individuals with weaker carinae have been treated as separate species (Knerer & Atwood 1966a).

The specimen of Halictus albipennis indicated above is designated herein as the lectotype to ensure future stability in the application of the name. Some of Robertson�s syntype series include more than one species, which could potentially lead to taxonomic confusion. An invalid lectotype led Gibbs (2010b) to treat the name Halictus nymphaearum as a junior subjective synonymy of L. albipenne (for discussion see Gibbs 2010b, below). Other subjective synonymies have also recently been made (Gibbs 2010b). The specimen of Halictus nubilis indicated above is designated herein as the lectotype to ensure future stability in the application of the name.

Diagnosis. Females of L. albipenne can be recognised by the diagnostic combination of a bluish green head and mesosoma, white wings with very pale yellow pterostigma and venation, coarse mesoscutal punctures which are sparse medially (i=1–3d), coarsely reticulate-rugose mesepisternum, strongly carinate propodeum, large and dense T1 acarinarial fan, and metasomal terga brown with dense tomentum and distinct punctures throughout. Females of this species are most similar to L. cressonii, L. disparile (Cresson), and L. oceanicum. Female L. cressonii are golden green on the head and mesosoma, have relatively dense mesoscutal punctures (i=1–1.5d) and faintly dusky wings. Female L. disparile have a distinct glabrate band on the declivitous surface of T1 separating the acarinarial fan from a dorsal pubescent band. Female L. oceanicum have a complete transverse carina separating the dorsal and posterior surfaces and distinctly reflexed hypostomal carina. Males of L. albipenne are similar to females but may be further distinguished by their elongate heads (length/width ratio = 0.99–1.08) with abundant white hairs obscuring the face, hyaline wings, relative short flagellomeres (length/width ratio = 1.21–1.31) which are bright yellow ventrally, and punctate-reticulate mesepisternum. Males of this species are most similar to L. pruinosum and L. oceanicum. Male L. pruinosum have a yellow apical maculation on the clypeus. Male L. oceanicum have a distinctly punctate tegula.
