Overview
Reprinted with permission from: Mitchell, T.B. 1960 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 141.


FEMALE—Length 4 mm.; head and thorax bluish-green, abdomen piceous, without conspicuous maculae; face slightly longer than distance between eyes; eyes parallel; cheeks subequal to eyes in width; vertex rather broad, lateral ocelli subequally distant from its hind margin and from eyes; foveae elongate, rather broad, quite deep and distinct; mandibles yellow with ferruginous tips; labrum dark ferruginous; clypeus rather narrow and elongate, protruding considerably below suborbital line, entirely piceous, with shallow, fine, well separated and rather inconspicuous punctures; facial mnculae absent; scape obscurely yellowish at extreme base anteriorly, otherwise dark, the flagellum pale brownish beneath, somewhat darker above; face and cheeks rather dull, the punctures barely evident; pubescence of head and thorax extremely short and thin, entirely white; thorax entirely dark, without maculae; tegulae yellowish-hyaline; wings subhyaline, veins pale testaceous, the stigma rather dark brownish; legs dark brownish, front tibiae yellow anteriorly and front tarsi entirely yellow; scutum and scutellum dull, almost black, the punctures very fine and indistinct, rather sparse, pleura more bluish-green, dull above, but somewhat shining below, with very fine but somewhat closer punctures; abdomen piceous, tergum 3 with a pair of very small, lateral, yellow maculations, but these sometimes absent, depressed apical margins of the terga concolorous with discs, the more apical terga with some fine, scattered, inconspicuous punctures.

MALE—Length 5 mm.; head and thorax dark greenish-piceous, abdomen entirely piceous, face with yellow maculae; face slightly shorter than distance between eyes; eyes parallel; cheeks considerably broader than eyes, without tubercles; vertex quite broad, but lateral ocelli considerably nearer its hind margin than to eyes; foveae somewhat elongated, rather deep and quite distinct, located near top of eyes; mandibles yellow, with ferruginous tips; labrum yellow; clypeus yellow except for a pair of small, lateral, brownish spots above; face marks broad and conspicuous, filling area between clypeus and lower margin of eye, extending about to level of antennae on inner margin of eye, supraclypeal area yellow; scape yellow anteriorly, dark posteriorly, flagellum testaceous beneath, slightly darker above; lower portion of face and cheeks somewhat shining, upper portion rather dull, punctures hardly evident; pubescence of head and thorax extremely short, thin, entirely white; thorax without distinct maculae, but tubercles somewhat brownish; tegulae yellowish-hyaline; wings subhyaline, veins pale testaceous, stigma somewhat more brownish; femora brownish, narrowly yellowish at tips, all tarsi and front tibiae entirely yellow, mid and hind tibiae brownish, becoming somewhat yellowish at base; scutum and scutellum dull, very dark green, punctures exceedingly minute, barely visible, rather sparse; pleura somewhat more shining, but with punctures even more indistinct; basal abdominal terga entirely impunctate, the more apical terga with barely evident, very minute and sparse punctures, surface of all somewhat shining; apical margin of sternum 6 broadly and shallowly incurved; apical margin of sternum 7 with a deep, broad, rounded, median emargination; apical portion of sternum 8 gradually narrowed to the rather abruptly and narrowly truncate tip, slightly compressed laterally, forming an obscure median longitudinal carina, tip with some short pubescence; gonostyli broad basally, rather short, somewhat curved and slender apically except for a dorsal, sharply compressed, rounded flange, penis valves slender apically, broadened toward base, slightly exceeding tips of the gonostyli, volsellae composed of a slender elongate cuspis and a considerably longer and much flattened digitus, the gonocoxites produced apically to form broadly rounded lobes.

DISTRIBUTION—Colorado to Illinois and Michigan, south to Florida; April to September.

FLOWER RECORDS—Physalis.

Timberlake (1958) in his revision of Perdita did not synonymize maura with halictoides, but indicated their close relationship, expressing the opinion that they probably are no more than forms of a single species. After his manuscript was submitted for publication, two males, apparently typical maura, came to hand which had been collected in Florida. These were sent to him, and he concurs in the opinion that they constitute strong evidence for the common identity of the two. Since these males were collected in the same general region in which typical halictoides females have been collected, it would seem that the differences between the two are due to individual variability rather than to any geographic racial distinction. The type of halictoides in the British Museum has been compared with a female collected in Florida and no differences could be found.


Identification
Extracted from: P.H. TImberlake. A Revisional Study of The Bees of the Genus Perdita F. Smith, with Special Reference to the Fauna of the Pacific Coast (Hymenoptera, Apoidea Part III). University of Caifornia Press Berkeley and Los Angeles 1958

Perdita halictoides F. Smith, 1853, Cat. Hym. Brit. Mus., 1:128, $; Cockerell, 1896, Proc. Acad. Sei. Phila., 48:77; Cockerell, 1904, Canad. Ent. 36:303; Timberlake, 1928, Proc. Hawaii. Ent. Soc, 7:155.

P. halictoides and maura have nearly identical characters of structure and color, but halictoides is considerably smaller, with three joints in the maxillary palpi, facial foveae less broad and more removed from eye margin, and head perhaps a little more distinctly longer than broad. It is perhaps doubtful that halictoides is more than a form of maura, but the two should be kept separate, until halictoides is better understood.

Female.—Dark blue-green, with a variable luster on mesonotum, the disk of which appears blackish in some aspects. No light markings but mandibles pale yellowish at base, grading through testaceous to red at apex. Abdomen blackish. Legs dark, the anterior tibiae, front and middle tarsi pale yellowish, the hind tarsi pale brown. Antenna dark, the flagellum yellowish beneath. Tegulae testaceous. Wings dusky hyaline, the nervures testaceous, the subcosta and stigma more brownish.

Head a little longer than wide because of the projecting clypeus. The latter large, the disk about as long as wide, with a little more than half in front of a line tangent to base of mandibles; lateral extensions of clypeus not visible in frontal aspect. Mandibles simple, tapering, and acute at apex. Facial foveae elongate, extending from level of middle of antennal sockets about four fifths of distance to level of anterior ocellus, slightly widened at their upper end and about their own width from margin of eyes. Proboscis moderately elongate and probably in repose would reach about the front coxae. Maxillary palpi short, thin, and three-jointed, the first joint about equal to the other two together. Labial palpi normal, elongate, and about equal in length to the galeae, which are rather slender and acute at apex. Tarsal claws very small and provided with a basal expansion. Stigma of wing rather broad but not equaling width of submarginal cells. Marginal cell rather short and broad, a little obliquely truncate at apex and with the parts beneath and beyond stigma equal. Pygidium rather broad, with the sides arcuately converging to the ogival apex. Head and thorax nearly uniformly tessellate, rather dull, and obscurely punctured, the punctures very fine except on clypeus. Pubescence moderately abundant for a Perdita, with hair erect, minutely plumose, and that of mesonotum moderately long. Front coxae with long, simple, and moderately sparse hair. Scopal hair of hind tibiae of about the usual density in most species of Perdita and twice as long as width of tibia. Length, 4.5 mm.; anterior wing, 3.2 mm.

The type locality of halictoides is North America without a more definite location. For this report one female has been examined from Coronado Beach, Volusia County, Florida, May 5, 1916 (J.C.Bradley).
