Holotype. ♀ CANADA, ONTARIO, Lambton Co., N43°13.981′ W081°51.90′, 20.vi.2008 (A. Taylor); [PCYU: ANT
5667]
Diagnosis. Females of L. taylorae can be recognised by the diagnostic combination of an elongate head
(length/width ratio = 1.001.07), sparse mesoscutal punctures between parapsidal lines (i=12.5d), incomplete
metapostnotal rugae reaching only 2/33/4 distance to posterior margin, metasomal terga polished
brown, T1 fan with wide dorsal opening, T2T3 with small basolateral patches of tomentum, and apical
impressed area of the T2 punctate. They are most similar to L. planatum which have the apical impressed area
of T2 impunctate.
Male unknown.

forewing length 3.874.05 mm.
Colouration. Head and mesosoma green with blue and gold reflections. Clypeus with apical margin
blackish brown, remainder and supraclypeal area brassy. Antenna dark brown, F8F10 with ventral surface
yellow-orange to brown. Tegula reddish amber. Wing membrane subhyaline, venation and pterostigma pale
amber. Legs brown, medio- and distitarsi reddish brown. Metasoma dark brown, terga and sterna with apical
margins reddish brown.
Pubescence. Dull white. Sparse. Head and mesosoma with moderately dense woolly hairs (11.5 OD),
longest on genal beard, metanotum and mesopleuron (22.5 OD). Gena with very sparse subappressed hairs.
Propodeum with moderately dense plumose hairs on lateral and posterior surfaces (22.5 OD). Metasomal
terga with sparse, fine setae. T1 acarinarial fan with dorsal opening equal in width to lateral hair patches. T2
T3 basolateral areas with sparse tomentum. T4 with tomentum sparsely scattered across disc.
Surface sculpture. Face imbricate. Clypeus polished, weakly imbricate, punctation strong (i=13d). Supraclypeal
area polished or weakly imbricate medially, punctation moderately sparse (i=12.5d). Lower paraocular
area punctation dense (i≤1d). Antennocular area punctation moderately sparse (i=11.5d). Upper
paraocular area and frons reticulate. Ocellocular area distinctly punctate (i=d). Gena lineolate. Postgena polished.
Mesoscutum imbticate anteromedially, remainder weakly imbricate to moderately polished, punctation fine, sparse between parapsidal lines (i=12.5d), close laterad of parapsidal lines (i≤d), contiguous on anterolateral
portion. Mesoscutellum polished, submedial punctation moderately dense (i=12d). Axilla punctate.
Metanotum imbricate. Preλpisternum rugulose. Hypoepimeral area weakly ruguloso-imbricate. Mesepisternum
rugulose dorsally, weakly ruguloso-imbricate ventrally, sometimes with obscure punctation throughout.
Metepisternum with dorsal half striate, ventral half imbricate. Metapostnotum rugoso-striate reaching 2/33/4
distance to posterior margin, posterior portion imbricate. Propodeum with dorsolateral slope rugulose, lateral
surface rugulose-tessellate, posterior surface imbricate. Metasomal terga polished, weakly coriarious, punctation
on basal halves sparse (i=12d), apical impressed area punctate laterally.
Structure. Head moderately wide (length/width ratio = 1.001.07). Eyes convergent below (UOD/LOD
ratio = 1.231.28). Clypeus projecting 1/22/3 below suborbital line, apicolateral margins convergent. Antennal
sockets close (IAD/OAD ratio < 0.5). OOD less than IOD. Gena narrower than eye. Inner metatibial spur
pectinate with 34 teeth. Metapostnotum moderately elongate (MMR ratio = 1.081.25). Propodeum with
oblique carina virtually absent, lateral carina not reaching dorsal margin.
MALE: Unknown.
Range. Ontario south to the District of Columbia (Fig. 219).

Lasioglossum (Dialictus) taylorae Gibbs, 2010b: 321. ♀.
Holotype. ♀ CANADA, Ontario, Lambton Co., N43°13.981′ W081°51.90′, 20.vi.2008 (A. Taylor); [PCYU: ANT 5667]
Diagnosis. Female L. taylorae can be recognised by the following diagnostic combination: head long (length/width ratio
