Overview |
Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.
FEMALE�Length 8 mm.; head chiefly black, antennae pale testaceous, labrum and mandibles more ferruginous, and clypeus somewhat infused with ferruginous; thorax ferruginous in large part, but venter blackened and propodeum entirely black; basal abdominal tergum feruginous, following terga largely black, but more or less reddish-hyaline along apical margins; space separating lateral ocelli from margin of vertex considerably less than their diameter; cheeks extremely narrow, posterior margin subcarinate; median length of labrum only slightly less than basal width, subapical denticles small but quite distinct; mandibles simple, inner margin nearly straight; posterior margin of scutellum nearly straight, axillae robust, tips acute and extended considerably beyond margin of scutellum (fig. 110); wings with the usual three submarginal cells, subhyaline, faintly clouded apically, veins piceous; cheeks and face around and below antennae densely silvery tomentose; venter of thorax quite densely tomentose, this becoming rather thin on pleura above, pronotum with a narrow but quite dense covering of white tomentum, scutum with a pair of narrow, anterior, longitudinal lines of white tomentum on each side of midline, and metanotum densely white tomentose below scutellum; basal abdominal tergum with a basal, densely white tomentose area, and terga 1-4 with dense, white, apical, tomentose fasciae which are rather widely interrupted medially, these slightly separated from hind margin of terga toward midline, tergum 5 with an area of rather thin white tomentum on each side; punctures quite deep and distinct but rather close in general, coarse and rather close on upper part of face, becoming minute and densely crowded below antennae, slightly separated on pleura below, becoming more or less crowded above, close and rather coarse over most of scutum, becoming crowded posteriorly and crowded on scutellum and axiline; tegulae minutely and very closely punctate; punctures fine and rather close and evenly distributed on discs of the more basal abdominal terga, becoming finer on the slightly depressed apical margins, but extending nearly to the yellowish rims, minute and close over most of tergum 5; pseudopygidium quite small and narrow, median length almost equal to apical width.
MALE�This sex agrees in most respects with descrition of female, but front of the face is more densely silvery tomentose, and usually there is a shining impunctate area near top of each eye on inner margin; pygidial plate rather broadly rounded, margin carinate, surface very obscurely and shallowly punctate.
TYPES � Holotype: Female, Arcadia, Desoto Co., Fla., Apr. 27, 1955. Allotype: topotypical (both M. A. & H. E. Evans) [Cornell University]. Paratypes: FLORI DA: 5 ♀♀, 4 ♂♂, topotypical; 1 ♀, 4 ♂♂, Levy Co., July 13, 1954 (H. V. Weems, Jr., on Eriogonurn tomentosum). [Fla. Plant Board].

Extracted from: Onuferko TM (2018). A revision of the cleptoparasitic bee genus Epeolus Latreille for Nearctic species, north of Mexico (Hymenoptera, Apidae). ZooKeys 755: 1–185. https://doi.org/10.3897/zookeys.755.23939
Diagnosis. The following morphological features in combination (excluding any that
are specific to the opposite sex of the one being diagnosed) can be used to tell E. floridensis apart from all other North American Epeolus: the axilla is large, with the tip extending
as far back as or beyond the posterior margin of the mesoscutellum, dilated laterally, and
like the mesoscutellum ferruginous; the mesopleuron is closely (i≤1d) and evenly punctate; T1 is (with few exceptions) ferruginous and with a distinct, although sometimes
medially-interrupted, basal fascia; the mesoscutum and metasomal terga have bands of
pale gray to white short appressed setae; at least the T1–T3 apical fasciae are distinctly
interrupted medially; and the pseudopygidial area of the female is lunate with the apex
<2 × the medial length. Epeolus floridensis is similar to E. howardi, but in E. howardi the
mesoscutum and metasomal terga have bands of bright or pale yellow short appressed
setae and the metasomal terga (including T1) are black. Epeolus floridensis is also similar
to E. packeri, but in E. packeri the T1 basal fascia is absent or reduced to a pair of small
patches of pale tomentum, the metasomal terga (including T1) are black, and the pseudopygidial area of the female is lunate with the apex >2 × the medial length.
Redescription. FEMALE: Length 7.5 mm; head length 2.1 mm; head width 2.7
mm; fore wing length 5.5 mm.
Integument coloration. Black in part, at least partially ferruginous on mandible,
labrum, clypeus, antenna, pronotal collar, pronotal lobe, tegula, axilla, mesoscutum,
mesoscutellum, metanotum, mesopleuron, metapleuron, propodeum, legs, T1, T5,
pygidial plate, and metasomal sterna. Mandible with apex darker than rest of mandible; preapical tooth slightly lighter than mandibular apex. Antenna brown and orange
in part. Pronotal lobe and tegula pale ferruginous to amber. Mesoscutum almost entirely reddish brown. Wing membrane subhyaline, apically dusky. Legs more extensively reddish orange than brown or black.
Pubescence. Face with tomentum densest around antennal socket. Tomentum
slightly sparser on clypeus; upper paraocular and frontal areas, and vertexal area mostly
exposed. Dorsum of mesosoma and metasoma with bands of off-white to pale gray
short appressed setae. Mesoscutum with paramedian band. Mesopleuron sparsely
hairy, but tomentum moderately dense along margins. Metanotum with tomentum
uninterrupted, uniformly off white. T1 with discal patch quadrangular and very wide,
the basal and apical fasciae only narrowly joined laterally by few sparsely scattered pale
hairs. T1–T4 with apical fasciae interrupted medially and somewhat broader laterally,
T2 with fascia without anterolateral extensions of tomentum. T5 with two patches of
pale tomentum lateral to and contacting pseudopygidial area. T5 with pseudopygidial
area lunate, its apex less than twice as wide as medial length, indicated by silvery setae
on impressed disc of apicomedial region elevated from rest of tergum. S5 with apical
fimbria of coppery to silvery hairs not extending beyond apex of sternum by more than
1/4 MOD.
Surface sculpture. Punctures dense. Labrum with larger and sparser punctures (i=1–
2d) than clypeus (i<1d). Upper paraocular and frontal areas, and vertexal area with
punctures equally dense. Impunctate spot lateral to lateral ocellus absent in holotype,
but shiny spot present in non-type specimens. Mesoscutum, mesoscutellum, and axilla coarsely and densely rugose-punctate. Tegula densely punctate mesally (i≤1d), less so
laterally (i=1–2d). Mesopleuron with ventrolateral half densely punctate (i≤1d), the interspaces shining; mesopleuron with punctures more or less equally dense throughout.
Metasomal terga with punctures very fine, dense (i=1–2d), evenly distributed on disc;
the interspaces shining somewhat.
Structure. Preapical tooth inconspicuous, blunt and obtuse. Labrum with pair of
small subapical denticles not preceded by carinae. Frontal keel not strongly raised.
Scape with greatest length 1.8 × greatest width. F2 noticeably longer than wide (L/W
ratio = 1.6). Preoccipital ridge not joining hypostomal carina, from which it is separated by about 1.5 MOD at its terminal (difficult to see in holotype; described from
non-type specimens). Mesoscutellum weakly bigibbous. Axilla large, its lateral margin
(L) more than half as long as mesoscutellar width (W) (L/W ratio = 0.6) and tip extending as far back as apex of horizontal dorsal portion of mesoscutellum; axilla with
tip clearly visible, but unattached to mesoscutellum for less than 1/3 the medial length
of axilla; axilla with lateral margin arcuate. Fore wing with three submarginal cells.
Pygidial plate apically truncate.
MALE: Description as for female except for usual secondary sexual characters and
as follows: upper paraocular area very finely and sparsely punctate in part, the interspaces shining; F2 shorter, but still longer than wide (L/W ratio = 1.3); S4 and S5 with
much longer coppery to silvery subapical hairs; pygidial plate apically rounded, with
large deep punctures closely clustered basomedially and sparser apically and laterally,
with the interspaces shining.
