FEMALE—Length 4.5 mm.; head and thorax dark bluish-green, abdomen piceous, maculae absent; length of face very slightly greater than distance between eyes; eyes sub- parallel; cheeks narrower than eyes; vertex rounded, its hind margin indefinite, lateral ocelli subequally distant from eyes and each other; foveae elongate, narrow, quite deep and distinct; mandibles pale yellow, tip piceous; labrum, clypeus and entire face greenish, without maculae, face and cheeks shining, very minutely and obscurely punctate; pubescence of head and thorax very short and thin, entirely white; thorax entirely dark, without maculae; tegulae yellowish-hyaline; wings whitish-hyaline, veins nearly colorless and very obscure, stigma somewhat more testaceous; legs dark, tarsi becoming yellowish apically; scutum and scutellum shining, sparsely and very minutely punctate; pleura rather dull, punctures even more obscure; abdomen entirely dark, without maculae, apical rims narrowly depressed, the more basal terga impunctate, the more apical terga becoming very minutely, sparsely and obscurely punctate.
MALE—Length 4 mm.; head and thorax bluish-green, abdomen piceous to almost black, without maculae; face almost as broad as its median length; eyes very slightly convergent below; cheeks subequal to eyes in width, with a ventral, rounded tubercle or protuberance; vertex rounded, its hind margin indefinite, lateral ocelli subequally distant from eyes and each other; foveae small, shallow and obscure; mandibles pale yellow, tips becoming pale ferruginous, not greatly elongated; labrum pale testaceous, subtriangular with cylindrical apex, length about equal to basal width; face entirely greenish, without maculae, clypeus short and very broad, width fully twice its median length; scape dark brown, becoming somewhat yellowish toward base, flagellum testaceous beneath on the more apical segments, piceous above; face below ocelli shining, punctures very minute and sparse on clypeus where they are distinct, hardly evident on other areas of face; pubescence of head and thorax rather short and thin, entirely white; thorax entirely green, without maculae; tegulae whitish hyaline; wings whitish-hyaline, veins and stigma nearly colorless and very obscure, stigma narrowly margined with brown, first intercubitus forked to form a small intercalary cell; legs piceous in large part, front tibiae yellow anteriorly, and all tarsi yellow; scutum and scutellum shining, punctures sparse and exceedingly minute and inconspicuous, hardly visible; pleura somewhat shining, punctures quite sparse and obscure; abdominal terga somewhat shining, apical rims rather narrowly depressed but dark, the more apical segments with very minute, sparse punctures; sterna 7 and 8 much as in floridensis (fig. 79); gonostyli short, compressed, more or less rounded apically, not equalling in length the slender penis valves, cuspis of volsellae compressed, nearly equalling the gonostyli in length, digitus slender, well developed.
DISTRIBUTION—North Carolina, Florida, Alabama and Mississippi, in June.

Identification | |
Extracted from P. H. Timberlake. 1947. NEW SPECIES OF PERDITA FROM THE SOUTHERN STATES
(Hymenoptera, Apoidea). University of California Citrus Experiment Station,' River-side, California This is a member· of the subgenus Allope1'difa Viereck.
and is easily distinguished from the other species by the entire
lack of light markings on the face, thorax, and abdomen . FemaZe.-Head and thorax dark green, the underparts nearly black.
Abdomen black, the apical margin of tergites tinged with tes~aceous.
Antennae and legs black, the tarsi testac~ous,. with outer margin of hind
basitarsus, and the front 'and middle basi tarsi, especially toward base,
dusky or blackish. Mandibles yellow testaceous at base, more reddish
at middle, and piceous at apex. Tegulae pale testaceous: Wbigs whitish
hyaline. Stigma testaceous, the nervures nearly colorless, except for the
brownish subcosta. Head a little broader than long, with inner orbits
slig~tly' diverging above. Head and thorax weakly, very finely tessellate,
. shining, the tessellation faint on disk of mesoscutum and on scutellum
and basal area of propodeum, and absent on clypeus and supraclypeal
area. Clypeus With well-separated,fine punctures. Remainder of face
and sides of frons with a 'f~w remote punctures. Mesonotum with fine,
widely spaced punctures. Pubescence sparse, 'vhitish. Fore wing with
a small supernumerary submarginal cell as in other Alloperdita. Length,
5 mm.; anterior . wirig, 3.3 mm~ Male.-Similar to female. Head and thorax dark blue. Apical tergite
of abdomen brownish testaceous. Labrum testaceous, prominent,
convex, tapering, blunt at apex, an~ thus nasiform. Mandibles, yellow
testaceous, becoming red at apex. Tarsi yellow testaceous. Tegulae
whitish hyallile. Wings as in female, except that' the stigm~ has a
hrownish margin. Head a little more transverse than in female, /its
anterior margin truncate except for the projecting labrum and supporting
apical middie of clypeal margin. Cheeks about as wide a~ width of
eye, hardly wider behind and abruptly truncate in front, with the outer
corner a little produced and sh~rp. Antennae reaching about apex of
tegulae; the flagellum stout, cy~indrical; the scape very short. Sculpt~
re about as' in female. Pubescence sp~rse, erect, whitish. Length,
4, mm.; ante~ior wing, 3.3 mm. Described from. 12 females (holQtype and paratypes), Hattiesburg,
. Mississippi, collecting pollen at :flowers of Oyrilla,
J \IDe 4, 1944 (C. D. Michener), in the Michener collection;
1 male (allotype), sandhills near Lillington, North Carolina,
June 13, 1941 (T. B. Mitchell), in collection of U. S. National
Museum, Cat. _ No. 58140. The Alloperdita group now includes four species: Perdita
novae-angliae Viereck, P. ,obsc1trata Cresson, P. floridensis
Timberlake, and P. mitchelli, n. sp. P. bradleyi Viereck also
belongs here, but is, I am sure, the male of obscurata Cres-son
(new synonymy) . .A.Uoperdita is restricted to the Atlantic
Coast and Gulf States,· from Massachusetts to Mississippi.
