Normaltica iviei new species

( Figs. 7, 8 , 11­17 , 19­22 , 25, 26, 29 , 43, 44 , 45, 46, 48 , 54 , 55, 57 , 59­65 )

Description. Body of medium size, length 1.94­2.32 mm, oval, relatively convex in lateral view. Color brown, without metallic luster, appendages paler. Eight apical antennomeres brown, darker than basal antennomeres.

Antennal calli poorly developed, their borders unclear so their shape and dimensions can not be determined. Supracallinal sulci absent. Supraantennal sulcus deep with acute borders. Vertex without small punctures. Anterofrontal ridge relatively low. Dorsal side of antennomere seven with peg­like structure, 1.1 times longer than dorsal side of antennomere eight.

Pronotum ( Fig. 19 ) 1.67 times wider than long, without impressions. Anterolateral callosity not angulate at setiferous pore. Basal dilation narrowly rounded. Punctures tiny, sparse.

Elytron ( Fig. 57 ) without humeral calli. Punctures tiny, ill developed, arranged in striae. Wing reduced in size with reduced set of veins, without two sclerites between radial cell and RP­mp2 ( Fig. 54 ), apical part of wing surrounded by long setae.

Spermatheca ( Fig. 62 ) with receptacle 1.67 times as long as horizontal part of pump. Internal side of receptacle convex, external side concave. Base of duct faces away from direction of receptacle. Tignum ( Fig. 65 ) less robust anteriorly, wider posteriorly. Vaginal palpus ( Fig. 64 ) less robust.

Median lobe ( Figs. 55 ) wider at apex than near middle, convex in lateral view.

Etymology. This species is named after Mike Ivie who brought the specimens to my attention. The species name is a noun in apposition.

Variability. Males of this species have no significant differences from females in external structures, including the mouthparts and head. The first tarsomere of the male is slightly wider than in the female, a character common to most flea beetles

Discussion. Normaltica iviei can be easily distinguished from N. obrieni with the following key.

Type material. Holotype. Labels: 1) Dominican Republic, LaVega, 53 km SE Constanza, August 9, 1979, L. B. O’Brien; 2) Holotype Normaltica iviei sp. nov. des. A. Konstantinov, 2002 ( USNM). Paratype 3, with same labels as holotype (2 USNM, 1 WIBF).
