Tomoglossa floridana Gusarov , sp. nov. ( Figs. 33 , 43­ 46 ) Type material: holotype ,, UNITED STATES : Florida : Highlands Co. , W Archbold Biological Station , [ 27 º 11 'N 81 º 20 'W ], “ sphagnum ex pond ”, 21 .i. 1975 ( W. Suter ) ( FMNH ) . Diagnosis. Compared to all other Nearctic species of Tomoglossa , T. floridana is the smallest and has shorter antennae with more transverse articles 4­10 ( Figs. 29­33 ). Tomoglossa floridana also differs from T. decora and T. ornatella in having different shape of spermatheca (especially the umbiculus) ( Figs. 45 , 27 , 36 ) and smaller female accessory sclerite ( Figs. 46 , 28 , 37 ). Description. Length 1.6 mm . Body and appendages reddish yellow; head and abdominal tergum VI dark brown; elytra brownish yellow with apical third yellow. Head transverse, surface on disk glossy, with weak reticulate microsculpture, with strong punctures, distance between them equal to their diameter. Antennal article 2 longer than article 3, 4­ 10 transverse, last article shorter than 9 and 10 combined ( Fig. 33 ). Pronotum transverse, width to length ratio 0.37 mm : 0.27 mm , wider than head (pronotum width to head width ratio 0.37 mm : 0.30 mm ); surface glossy, with weak reticulate microsculpture, puncturation finer than on head, distance between punctures equals their diameter. Elytra measured from humeral angle shorter than wide ( 0.33 mm : 0.37 mm ), surface glossy, with weak reticulate microsculpture, puncturation finer and denser than on pronotum, distance between punctures equals ½­ 1 their diameter. Abdominal terga glossy, without microsculpture, and with fine and sparse puncturation, puncturation becoming finer towards abdominal apex, on terga III­V distance between punctures within rows equal to their diameter and between rows 2­3 times their diameter, on tergum VI distance between punctures within rows equal to 1­2 times their diameter and between rows 2­4 times their diameter, on tergum VII distance between punctures within rows equal to 2­3 times their diameter and between rows equal to 4­6 times their diameter. Tergum VII with white edge. FIGURES 43­46. Details of Tomoglossa floridana Gusarov , sp. nov.
