Caillardia springatei Spodek & Burckhardt , sp. nov.

( Figs 2‒7, 9 , 11, 13, 14 )

Material examined. Holotype ♂, Israel: CN: Makhtesh Ramon, Wadi Ramon, 29.iii‒5.iv.2000 (N.D. Springate) (SMNHTAU, dry mounted) . Paratypes. Israel: AV: 1 ♂, Hazeva , Wadi Shahaq, 22‒29.iii.2000 (N.D. Springate) ( NHMB, dry mounted); CN: 2 ♂, 1 ♀, same as holotype ( NHMB and SMNHTAU, dry and slide mounted).

Description. Adult. Colour. General body colour white with small orange spots. Antenna white. Eyes white sometimes with small orange flecks; ocelli orange. Tip of labium black. Pronotum, mesopraescutum and mesoscutum white with small orange spots. Forewing ( Figs 2, 7, 9 ) with white membrane and white veins; scattered brown spots uniform, sparser and darker in basal half, denser and very light in apical half, spots lacking on irregular transverse band stretching between apices of veins R1 and Cu1b; pattern in male ( Fig. 7 ) darker and more contrasted than in female ( Fig. 9 ). Hindwing white. Metacoxa and metafemur white with small orange spots; other leg segments white. Abdomen brown, terminalia light brown.

Structure. Head inclined almost 90º from longitudinal body axis; narrower than thorax. Vertex ( Fig. 5 ) flat, subrectangular. Clypeus elongate, heart-shaped, flattened. Antenna ( Fig. 3 ) filiform, shorter than half width of head, with subapical rhinarium on each of segments 4, 6, 8 and 9; scape and pedicel much thicker than flagellum, segment 3 longer than segments 4 and 5 together, segments 5 and 7 shorter and more slender than segments 4 and 6, respectively, segments 3 and 8 weakly, segments 4–7 strongly widening to apex, segments 9 and 10 more or less of the same width; longer terminal antennal seta slightly curved, slightly longer than segment 10, shorter seta straight, slightly shorter than segment 10 ( Fig. 4 ). Forewing ( Figs 7, 9 ) broad, nearly rhomboidal with almost straight fore margin distal to strong bent of vein C+Sc which is more or less in its middle, cell c+sc about 1.5 times as wide as length of vein R; pterostigma narrow, vein Rs almost straight; wing apex irregularly rounded; membrane leathery, with indistinct, densely and irregularly spaced surface spinules ( Fig. 6 ) covering membrane up to the veins. Hindwing bearing 11–13 costal setae distal to costal break which are not grouped. Hind leg with slender metacoxa bearing a knob-like meracanthus; part between base of meracanthus and trochanteral insertion straight. Female and male terminalia as in Figs 11 and 13 . Male proctiger with long posterior processes which are straight and slightly narrowing to apex which is strongly up-turned. Male subgenital plate large, irregularly subglobular, shorter than high, in profile. Paramere ( Fig. 14 ) slightly longer than proctiger, about 1.5 times as long as wide, bearing an irregularly rounded lobe at antero-apical edge, postero-apically rounded, hind margin with abrupt angle in middle; inner face with an inner, strongly sclerotised lobe on basal half and strongly sclerotised tooth in the middle of hind margin. Distal portion of aedeagus with short anterior hook and large posterior membranous saclike extension; sclerotised end tube of ductus ejaculatorius very long, weakly sinous. Female terminalia cuneate, dorsal margin of proctiger weakly sinuous, almost straight, apex strongly up-turned.

Measurements in mm and ratios (1 ♂, 1 ♀). HW 0.7–0.75; WL 1.7–2.1; WW 0.9–1.2; TL; 0.5; MP 0.3; PL 0.3; AEL 0.25; FP 0.9; CR 0.3; SP 0.7; WL/HW 2.43–2.80; WL/WW 1.75–1.89; TL/HW 0.67–0.71; MP/HW 0.43; FP/HW 1.2; FP/CR 3; FP/SP 1.29.

Immatures unknown.

Host plant. Unknown.

Comments. Caillardia springatei sp. nov. is closely related to Caillardia maroccana Loginova , based on the dotted forewing with a light transverse band in the middle and the apically up-turned female proctiger. This corresponds to species-group 1 of Loginova (1978). C. springatei differs from C. maroccana in the more rhombic forewing ( Figs 7, 9 ) (oval and narrower in C. maroccana , Figs 8, 10 ) with a wider cell c+sc (versus only about as wide as vein R long), a more irregularly rounded wing apex (evenly rounded), the straight Rs (versus weakly curved away from fore margin), the weakly narrowing posterior lobes of the male proctiger (versus with subparallel margins), the almost straight dorsal margin of the female proctiger ( Fig. 11 ) (versus strongly concave distal to the circumanal ring, Fig. 12 ), and details of the paramere ( Figs 14, 15 ).

Etymology. This species is named in honor of Neil D. Springate (U.K), who collected the type specimens.
