Type locality. United States, area including Virginia, North Carolina, South Carolina , eastern Tennessee, Georgia, Alabama, Mississippi, Florida, Arkansas, Louisiana.

Type information. Holotype. Elytroleptus floridanus ( MCZC, ♀) labeled: ‘[orange disc = Southern States; Gulf States; Va., N.C., S.C., eastern Tenn.?, Ga., Ala., Miss., Fla., Ark.? La.]/ Pteroplatus ? floridanus Lec. /Type 3896/ Elytroleptus floridanus Lec. ’

Diagnosis. This species is distinguished from all other species of Elytroleptus by the following combination of characters: 1) elytral margins subparallel, greatest width <1.5 × humeral angle width, 2) pronotal lateral margins broadly rounded 3) pronotum with two longitudinal lines of dense, appressed, testaceous pubescence overlying testaceous integument, and 4) pronotum and elytra with deep, moderate to large punctation. This species most closely resembles E. immaculipennis and is distinguished by the longitudinal lines of dense pronotal pubescence testaceous overlying testaceous integument instead of white to pale yellow pubescence overlying red integument.

Description. Male. TL 6.7–9.5 mm, GW 2.0– 3.3 mm. Body elongate, subparallel, dorsoventrally flattened.

Head. HL 0.5–0.7 mm, HW 1.0– 1.5 mm, DBE 0.6–0.8 mm, DBA 0.4–0.6 mm. Piceous, except labrum, anteclypeus, and vertex with triangular area testaceous. Finely punctate with short, sparse, suberect to erect, black pubescence, except testaceous pubescence over testaceous integument areas; gular region glabrous; rugose posterior to lower eye lobe. Antennal tubercles slightly raised and separated by approximate width of four antennal emarginate at antennal insertion, with 1–3 facets at greatest emargination point. Antennae black, extending to approximately 2/5 elytral length, scape and antennomere III, IV, and V subequal; pedicel about 1/2 × scape length; antennomeres V and VI subequal; antennomeres V–IX decreasing in length; antennomere XI subequal to VII and weakly appendiculate.

Thorax. PL 1.0– 1.6 mm, PW 1.2–1.9 mm. Pronotum piceous, width slightly greater than length, apical width subequal to basal width; lateral margins broadly rounded, widest medially. Pronotal disc shining, punctate, with short, recumbent, black pubescence arising from punctation; laterad to center, two (one on each side) distinct longitudinal, arcuate lines of dense, appressed, testaceous pubescence overlying areas of testaceous slightly raised integument, each of similar width throughout and occupying ¼ of pronotal disc area; punctation on shining areas deep, individual punctures moderately sized in diameter, evenly spaced and each individual puncture strongly delimited; oval, more densely punctate areas dorsad of lateral margin indicative of sexually dimorphic gland pores; pronotal disc flat to slightly convex; sides impressed in dorsal aspect, margin apparently elevated, calli absent. Pro-, meso-, and metasternum piceous, shining, with sparse, suberect to erect, pale setae. Scutellum piceous, small, subtriangular, length subequal to width, medially impressed, with short, moderate, black pubescence.

Wings. EL 5.2–7.2 mm. Elytron with basal 1/5 testaceous, apical 4/5 piceous extending anteriorly to obliquely meet suture, margin irregular. About 4.5 × pronotal length, width at humeral angles subequal to greatest width of pronotum. Elytron subparallel, greatest width <1.5 × width at humeral angle. Elytron with 3 distinct costae; from suture, costa I arising from anterior margin and extending to 3/5 elytral length, costa II arising from anterior margin and extending to 4/5 elytral length, costa III arising from humeral angle and extending to 4/5 elytral length; elytron with distinct punctation, 3–4 punctures medially between suture and costa I, distinct apically, subequal basally; elytron with sparse, short, recumbent pubescence, one seta per puncture, testaceous on pale-colored areas, black on dark-colored areas, outer elytral margins with pubescence more dense. Metathoracic wing completely darkly tinted.

Abdominal Sternites. Piceous, shining, finely punctate with short, sparse, suberect, pale pubescence. Legs. Piceous. Femora and tibia sparsely punctate and covered with short, erect, black pubescence. Tarsi covered with short, recumbent, black pubescence. Metatibia straight, not sinuate. Genitalia. Sternite VIII sides gradually tapering towards apex, four slightly sinuate anterolateral areas (two on either side), often with slight concavity medially. Tergite VIII gradually tapering towards apex, lacking sinuate areas, often with slight concavity medially. Female. TL 6.8–10.7 mm, GW 2.1–3.8 mm, HL 0.5–0.6 mm, HW 1.1–1.5 mm, DBE 0.7–0.9 mm, DBA 0.5–0.6 mm, PL 1.0– 1.7 mm, PW 1.4–2.2 mm, EL 5.3–8.4 mm. As male, except elytra about 5 × as long as pronotal length; sexually dimorphic oval area of dense punctation dorsad of pronotal lateral margins absent.

Intraspecific variation. Elytral coloration varies from above description to only humeral angles testaceous.

Remarks. Though this species is extremely similar in form to E. immaculipennis , it appears to be a valid species given the consistency of the color differences coupled with its unique geographic distribution and flight period.

Phylogenetic relationship. This species is sister to E. immaculipennis supported by the male 8 th sternite lateral sides each with two strongly sinuate areas (Character 20) ( Figs. 31 , 32 ).

Distribution. Eastern to southwestern USA (Arkansas, Florida, Georgia, Kansas, Maryland, Massachusetts, Mississippi, New Jersey, New York, North Carolina, Oklahoma, Rhode Island, South Carolina, Tennessee, Texas) ( Fig. 34 ).

Natural history. Flight period February through June. Adults have been collected by beating oak ( Quercus spp. including Quercus alba L., Quercus laevis Walter , and Quercus nana Willd. ). Two specimens have label data indicating that they were found washed up on the beach shore. Linsley et al. (1961a) suggested that the lycid model for this species is Lycus lateralis (Melsheimer) .
