Triepeolus georgicus Mitchell 1962: 469–470, Fig.112 [Holotype: U. S. National Museum of Natural History No. 400192; female, Fort Gordon, Richmond Co., Georgia; 24 September 1958].
Triepeolus floridanus Mitchell 1962: 468–469 [Holotype: Florida State Collection of Arthropods; male, Gainesville (Alachua Co.), Florida; 28 October 1956]. new synonymy
Description.—Length ca. 11 mm; ITW 2.2–2.3 mm. Integument black, with red on distal half of mandible and sometimes on F1; dorsum of mesosoma and metasoma with bands of pale gray to white setae. Tegula more or less transparent on apical margin. Clypeus with weak midline, lacking or with weak larger punctures, nearly or entirely asetose. Paramedian band connected laterally to diffuse white setae on anterior margin of mesoscutum, or barely distinct in some females. Scutellum moderately to strongly bigibbous; axillar spine reaching or slightly surpassing scutellar midpoint, weakly incurved apically. Mesepisternum lacking erect, simple setae; punctures spaced up to two puncture diameters apart, integument between flat; with dense, white, branched setae mostly restricted to dorsal half or fourth. T1 discal patch transversely ovate; T2 with LLB of pale setae forming weakly acute angle with ATB (mostly on lateral margin of T2). Female: Pseudopygidial area ovate, with distinct basal shining setae; S2–S4 with white setae on apical, or only apicolateral, margins (sometimes faint on S2); S5 weakly downcurved apically. Male: Pygidial plate moderately wide, weakly keyhole shaped, with distinct basal transverse ridge; S2–S3 with white setae apically; S4–S5 with brown apical fringes (sometimes with small patch white setae on apicolateral margin of S4).
Comments.—This species is very similar to T. donatus, but T. georgicus lacks erect, simple setae on mesepisternum and the clypeus is not elongate. Triepeolus georgicus is also similar to T. atripes, except in T. georgicus the clypeus is more convex in profile, with a modest midline (as opposed to a relatively flattened clypeus with a strong midline), the integument of the ventral half of the lateral surface of the mesepisternum is relatively flat, with punctures separated by up to a puncture diameter (as opposed to almost contiguous, with the integument between the punctures raised, slightly tuberculate in appearance), and in females, the paramedian bands reach the anterior margin of the mesoscutum, the pseudopygidial area has a basal crescent that is shorter than that of T. atripes, and S5 is slightly less downcurved. Triepeolus georgicus is less likely to be confused with T. cressonii, but can be distinguished from that species by the pale gray to white band coloration and black integument except for the mandibles and F1 (as opposed to pale yellow band coloration, usually with at least some areas of red integument on the legs and face in T. cressonii).
As in T. obliteratus, the number of submarginal cells in this species appears to be labile: there is a tiny “fourth” submarginal cell in one wing of the holotype of T. floridanus.
Distribution.—USA: Florida, Georgia, Mississippi.
Seasonal Records.—24 September to 28 October.
Specimens examined.—6 female, 3 male (GAINESVILLE, STARKVILLE, WASHINGTON D.C.).

FEMALE—Length 11.5 mm.; entirely black, including labrum, mandibles, tubercles, tegulae and legs; basal segment of flagellum ferruginous in part, considerably shorter than segment 2, median segments somewhat longer than broad, piceous beneath, black above, the scape and pedicel black; space between margin of vertex and lateral ocelli less than half their diameter; cheeks very narrow, little more than one third width of eye, carinate posteriorly; median length of labrum slightly more than half the breadth, apical margin with a submedian pair of very minute denticles; posterior margin of scutellum broadly outcurved, slightly impressed medially, free part of axillae short, but reaching mid transverse line of scutellum (fig. 112) ; wings subhyaline basally, becoming very faintly infuscated apically, with the usual three submarginal cells, veins piceous; face above clypeus and around bases of antennae quite densely silvery tomentose, cheeks rather thinly tomentose, area just below ocelli with more elongate, erect, thin, whitish pubescence; margin of pronotum with a narrow, white tomentose band that continues as a marginal fringe around tubercles; pleura above rather densely whitish tomentose; scutum with a submedian pair of elongate, tomentose patches anteriorly, lateral margins thinly tomentose, and scutello-mesothoracic suture with a very fine line of whitish tomentum; metanotum and adjacent margin of scutellum whitish tomentose, with a tuft of elongate, whitish hairs at each end posterior to wing bases; posterior face of propodeum rather thinly white tomentose, becoming more densely so at extreme sides, triangle completely bare; basal abdominal tergum whitish tomentose on anterior face, and with a subapical tomentose band which is slightly interrupted medially, these rather narrowly united at each extreme side, the resulting black tomentose patch very broad; tergum 2 with a subapical, tomentose fascia which is subinterrupted medially, and a somewhat oblique patch at extreme side which unites with the fascia and reaches the basal margin; terga 3 and 4 with transverse, whitish tomentose fasciae that on 3 slightly removed from rim, that on 4 nearly apical; tergum 5 with a whitish tomentose patch on each side of pseudopygidium; tegulae very minutely and closely punctate along inner margin, becoming rather narrowly impunctate laterally, more broadly so posteriorly; punctures of face below ocelli deep, distinct, quite coarse and well separated but hardly sparse, becoming more sparse between ocelli and eyes above, minute and slightly separated on the shining cheeks; anterior and median areas of scutum with deep, distinct, slightly separated punctures which are not very coarse, becoming somewhat more finely and densely punctate posteriorly, the scutellum rather finely rugoso-punctate, axillae with fine, slightly separated punctures; pleura below shining between rather fine but distinct punctures, interspaces slightly greater than diameter of punctures in general, but becoming densely and finely rugoso-punctate above; discs of abdominal terga beneath the black tomentum with fine and regular but quite distinct, slightly separated punctures throughout; pseudopygidium about as broad as the median length, broadly outcurved apically, covered with short, fine, suberect, fuscous setae, but lateral basal areas becoming more densely fuscous tomentose; sternum 5 broadly convex as seen from beneath.
TYPE—Holotype: Female, Fort Gordan, Richmond Co., Ga., Sept. 24, 1958 (R. R. Snelling). [author’s coll.].
