4. Tomoglossa arizonica Gusarov, sp. nov. (Figs. 32, 38­42)

Type material: holotype,, UNITED STATES: Arizona: Graham Co., Roper Lake State Park, 5 miles S Safford, [32º45'N 109º42'W], 900m, 12.v.1986 (L.Herman) (AMNH) .

Diagnosis. Tomoglossa arizonica differs from T. ornatella, T. improvisa and T. decora in having transverse antennal articles 4­5 (Figs. 29­32) and shorter body. Compared to T. floridana, in T. arizonica antennal articles 4­10 are less transverse, article 11 is as long as 9 and 10 combined (Figs. 32­33) and the body is longer. Tomoglossa arizonica also differs from T. decora in having shorter apex of median lobe of aedeagus (in lateral view) (Figs. 40, 21).

Description. Length 1.8 mm. Head, elytra, abdominal tergum VI, antennal articles 2­ 11 and article 3 of maxillar palpus reddish brown; pronotum and abdominal segments III­ V and VII­VIII reddish yellow; apical quarter of elytra, legs, mouthparts and antennal article 1 yellow.

Head transverse, surface on disk glossy, without visible (at x100) microsculpture, with fine and dense punctures, distance between them equal to ½ their diameter. Antennal article 2 longer than article 3, 4­10 transverse, last article as long as 9 and 10 combined (Fig. 32).

Pronotum transverse, width to length ratio 0.37 mm: 0.29 mm, wider than head (pronotum width to head width ratio 0.37 mm: 0.31 mm); surface glossy, without visible microsculpture, with puncturation as on head. Elytra measured from humeral angle shorter than wide (0.36 mm: 0.43 mm), glossy, without microsculpture, puncturation finer and denser than on pronotum, distance between punctures equal to ¼­½ their diameter.

Abdominal terga glossy, without microsculpture, 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 3­6 times their diameter. Tergum VII with white edge. Median lobe of aedeagus with narrow apex (Figs. 41).

Distribution. Known only from Arizona (Fig. 47).
