Type material. Holotype ♀ ( CNC #540731 ): top label “ U.S.A. FL: Indian River Co., Fellsmere , St Sebastian River Preserve State Pk, 27.III.2013, CSE399, ex.”; bottom label: “ Ectoedemia hypericella on Hypericum #1, emg. 30.iv.2013, C.S. Eiseman, CNC540731 ”. Paratypes: 1 ♀ ( CNC #540729 ) and 2♂ ( CNC #540730 , 540014 ), same as holotype ; 1 ♀ ( CNC #540018 ), same as holotype, emg. 7.V.2013, CSE467 ; 1♀ ( CNC #540011 ), same as holotype, emg. 28.IV.2013, CSE367 ; 1♀, same as holotype, emg. 25.IV.2013, CSE345.

Description of holotype, ♀. Body length: 1.55 mm; fore wing length: 1.3 mm.

Color. Head and mesosoma orangish brown; mesoscutum posteriorly and scutellum dark brown; metanotum and propodeum black. Antenna dark brown with orangish brown scape. Metasoma pale brown. All legs with yellow coxa, trochanter, trochantellus and femur honey yellow to light brown, tibia and tarsi dark brown except tarsomeres 1–4 of mid-leg whitish yellow. Wings with two distinct wide fuscous bands.

Head. Length of head in dorsal view 0.6× longer than wide. Antennae about as long as body; scape 2.0× longer than wide; subapical flagellomeres not expanded ventrally, all flagellomeres longer than wide. Eye height 5.5× longer than malar space. Frons and vertex rugose-areolate; temples finely areolate-rugulose; face finely areolaterugulose; clypeus superficially rugose. Clypeus with ventral border convex, evenly curved.

Mesosoma. Mesoscutum and scutellum densely punctate to finely areolate-rugulose. Notauli absent. Scutellar sulcus deep and narrow, with 8 divisions. Mesoscutellar trough costate. Metanotum rugose-costate. Pronotum smooth and polished with fine longitudinal rugose-striation ventrally, ventral groove absent. Sternaulus shallow, extending over most of mesopleuron, mostly smooth or weakly rugose. Mesopleuron mostly smooth, weakly punctate anteriorly; mostly setose but bare dorsally; subalar groove crenulate, deep and narrow. Propodeum mostly polished with irregular surface especially at median dorsal aspect, with complete transverse carina, dorsal aspect with two pairs of longitudinal carinae, posterior aspect with a pair of carinae diverging from posterior knob. Metapleuron finely and weakly costate.

Wings. Vein r absent, veins 2RS and 3RSa directly connected with stigma, vein R1 0.16× stigma length, stigma 3.2× longer than high.

Legs. Hind tibial spurs 0.23× the hind tibia length. All legs smooth. Mid coxa with transverse sulcus dorsally. Hind tibia enlarged apically, narrower than hind femur, 5.0× longer than its maximum width

Metasoma. All terga smooth, including mid basal furrow on T1, the furrow is shallow and not delineate.

Variation. Body length 1.50–1.65 mm

Male. Virtually identical to female with antenna relatively longer, 1.2× longer than body, as compared with about as long as body in females.

Diagnosis. The new species is distinguished by the fore wing vein r absent, veins 2RS and 3RSa directly merging into stigma; body mostly dark colored, including antennae usually entirely dark brown, and wings distinctly banded; scutellum densely setose; propodeum with complete transverse carina and two pairs of longitudinal carinae; vertex entirely finely areolate-rugulose; mid-basal depression of T1 shallow and not distinctly marked. Adelius floridensis sp. n. resembles A. coloradensis in having a densely setose and punctate scutellum. The two species are readily distinguished by sculpturing of vertex entirely areolate-rugulose in A. floridensis , whereas only partially striate-rugose in A. coloradensis . The mid-basal depression in A. floridensis is relatively shallow and not distinctly marked, but in A. coloradensis the depression is deeper and well-marked, frequently partly sculptured.

Biology. All specimens in the type series were reared from mines of Ectoedemia hypericella (Braun, 1925) (Nepticulidae) in leaves of Hypericum sp. ( Hypericaceae ). The time span from collection of the leaf mine to emergence of the adult wasp was 29–39 days.

Distribution. Known only from the state of Florida, USA.

Etymology. The species is named after the state of Florida, USA.
