description: 1. <i>Tomoglossa decora</i> (Casey, 1910), comb. nov. (Figs. 1 ­28, 31) <i>Noverota decora</i> Casey, 1910: 91. <b>Type material:</b> Lectotype (here designated),, <b>UNITED STATES:</b> “Miss[issippi].” [Vicksburg], “ <i>decora</i> Csy. ”, “Casey bequest 1925 ”, “ TYPE USNM 39100 ” (red label), “ Lectotype <i>Noverota decora</i> Casey. V.I.Gusarov des. 2002 ” (red label) (NMNH). While describing <i>N. decora</i>, Casey did not specifically state how many specimens were available. <b>Additional material: UNITED STATES: Vermont:</b>, Windsor Co., 8 km SEE Springfield, Hwy. I­91, 43º14.00'N 72 º 26.81 'W, 250m, in forest litter, <i>Acer</i>, <i>Betula</i>, <i>Tsuga</i>, <i>Quercus</i>, 21.ix. 1998 (V.I.Gusarov) (DESPU <b>); Pennsylvania:</b>, Easton, 5.x. 1917 (J.W.Green) (CAS);, ditto but 24.viii. 1917 (CAS); <b>Arkansas:</b>, Garland Co., 28.6 km NWW Hot Springs, Ouachita National Forest, Lake Ouachita, CR127, 34º 36.67 'N 93 º 20.75 'W, 300m, in forest litter, <i>Quercus</i>, 19.iii. 2000 (V.I.Gusarov) (DESPU). <b>Diagnosis.</b> <i>Tomoglossa decora</i> is close to the Palaearctic <i>T. luteicornis</i> but has lighter coloration and different shape of the aedeagus and spermatheca (Figs. 21­26 in this paper and Lohse 1989: Fig. 123). <i>Tomoglossa decora</i> differs from <i>T. ornatella</i> and <i>T. improvisa</i> in having quadrate antennal articles 4­5 (Figs. 29­31), from <i>T. arizonica</i> and <i>T. floridana</i> in having quadrate antennal articles 4­5, less transverse articles 6­10 (Figs. 31­33) and longer body. In comparison to <i>T. floridana</i> and <i>T. ornatella</i>, <i>T. decora</i> has thinner spermatheca with different shape of umbiculus (Figs. 26, 36, 45). In <i>T. decora</i> the female accessory sclerite is smaller than in <i>T. ornatella</i>, but larger than in <i>T. floridana</i> (Figs. 28, 37, 46). <i>Tomoglossa decora</i> also differs from <i>T. arizonica</i> in having longer apex of the median lobe of aedeagus (in lateral view) (Figs. 21, 40). <b>Description.</b> Length 2.0­ 2.1 mm. Head and elytra dark brown; elytra and antennal articles 2­11 and article 3 of maxillar palpus brown; pronotum reddish brown; abdominal segments III­V and VII­VIII reddish yellow; apical third of elytra, legs, mouthparts and antennal article 1 yellow. Head transverse, surface on disk glossy, without visible (at x 100) microsculpture, with strong punctures, distance between them equal to their diameter. Antennal article 2 longer than 3, 4­ 5 quadrate, 5­10 slightly transverse, last article as long as 9 and 10 combined. Pronotum transverse, width to length ratio 0.41 mm: 0.33 mm (average for 5 specimens), wider than head (pronotum width to head width ratio 0.41 mm: 0.35 mm); surface glossy, without visible microsculpture, with finer puncturation than on head, distance between punctures equals ½­ 1 their diameter. Elytra measured from humeral angle shorter than wide (0.43 mm: 0.48 mm), glossy, without microsculpture and with puncturation as on pronotum. 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 3­4 times their diameter, on tergum VII distance between punctures equal to 3­5 times their diameter. Tergum VII with white edge. Median lobe of aedeagus with narrow apex (Fig. 22). Internal sac with a deeply concave sclerite (Figs. 23­24). Copulatory piece without apical process (Figs. 23, 25). Spermatheca with wide umbilicus (Fig. 26). <b>Distribution.</b> Known from Eastern United States (Vermont, Pennsylvania, Arkansas, Mississippi) (Fig. 47). <b>Natural History.</b> Casey (1910) did not provide habitat information. I collected two specimens by sifting forest litter. Interestingly, the Palaearctic species of <i>Tomoglossa</i> for which ecological information is available inhabit various kinds of wetlands, including salt marshes.
