Diagnosis. FEMALE. The female of this species can be separated from other Dasymutilla by the following combination of characters: the lateral margin of the head behind the eye gradually curves inward, leading into tubercles on the postero-lateral margin of the head ( Fig. 5 View FIGURES 1 – 8. 1, 2 ); there are no transverse carinae anterior to the scutellar scale; the propodeum is covered with numerous small tubercles dorsally; the lateral face of the propodeum has dense silver setae that obscure the punctation; and the apical fringe of T2 is mostly silver, being interrupted by a small medial spot of black setae ( Fig. 10 View FIGURES 9 – 23 ). MALE. The male of this species can be separated from other Dasymutilla by the following combination of characters: there are silver setae on the apical terga, there is no setafilled pit on S2, and the cuspis is less than 0.7x the free paramere length ( Figs 40, 41 View FIGURES 36 – 71 ).
Description of male genitalia ( Figs 40–43 View FIGURES 36 – 71 ). Free length of paramere dorsally curved apically, with ventral brush of long dense setae basally, remainder having scattered short sparse setae; paramere laterally kinked in basal 0.3, apices slightly divergent. Cuspis roughly cylindrical, ~0.6 × free-length of paramere, having sparse short setae throughout. Densely setose basal lobe present. Digitus laterally curved internally, tapering slightly at apex, asetose, ~0.4 × free-length of paramere. Penial valve emarginated anterodorsally, ventral margin bidentate apically, teeth separated, unidentate medially; having longitudinal row of setae at apex and subapically on external margin.
Length. Females: 4.5–9.5 mm; males: 5–8 mm.
Host. Unknown.
Distribution. This species is currently known only from Florida, but because specimens have been found in the northeastern Clay and Bradford Counties, this species potentially could occur north into Georgia and South Carolina .

Remarks. Mickel (1928) synonymized this species with D. chattahoochei , because he considered the holotypes of the two species to be identical. He stated that the difference in head shape ( Figs 5, 8 View FIGURES 1 – 8. 1, 2 ) was inadequate to support species-distinction, and species identification using this character would differ based on specimen orientation. Although the distinction in head shape is subtle and difficult to recognize, we found it to be consistent for separating these species. Two additional characters separate D. arenneronea from D. chattahoochei , the lateral propodeal setae and the apical fringe of T2, but these are also difficult to use. Even so, we resurrect D. arenerronea , because male morphology and DNA sequences ( Fig. 73 View FIGURE 73 ) clearly differentiate these insects from D. macilenta (which now includes D. chattahoochei ).
Males of D. arenerronea were initially associated with D. chattahoochei by Krombein (1954) based on misidentified specimens. Krombein (1954) provided a detailed description for these males, except the genitalia, which are described above.
This species is clearly a member of the D. monticola species-group based on morphology and phylogenetic position ( Fig. 72 View FIGURE 72 ), even though the female was initially placed into the D. quadriguttata species-group. Krombein (1954) cited the D. arenneronea sex association as the second example of the combination of these two speciesgroups, after D. canella from the D. monticola species-group was associated with D. rugulosa from the D. quadriguttata species-group ( Krombein, 1951).
