Treatment

Diaphorina teucrii Burckhardt View in CoL , sp. nov.

( Figs 1, 2, 5 View FIGURES 1 – 6 , 7–14 View FIGURES 7 – 12 View FIGURES 13 – 16 )

Material examined. Holotype ♂, Israel: Borot Loz, 30°29’N 34°33’E, 12.v.2013, Teucrium capitatum (N. Dorchin) , ( TAUI, dry mounted).

Paratypes. Israel: 2 ♂, 3 ♀, 2 immatures, same data as holotype but ( TAUI, NHMB, dry and slide mounted).

Diagnosis. Adult body covered in long conspicuous setae. Genal processes 0.5–0.6 times as long as vertex along mid-line, asymmetrical. Forewing with semitransparent membrane bearing well defined dark brown pattern, widest in the middle, fore margin relatively evenly curved. Paramere clavate, weakly dilated in apical third, apex blunt. Ventral margin of female subgenital plate with distinct angle in the middle. Last instar immature with antennal segment 3 bearing each a lanceolate seta near the two basal rhinaria. Margin of abdomen with 22+22 to 25+25 lanceolate setae along caudal plate and 2+2 lanceolate setae cephalad of caudal plate. Outer circumanal ring consisting of a single row of pores.

Description. Adult. Colour. General body colour yellowish to light ochreous. Antenna yellowish, segment 8 brown, segments 9 and 10 dark brown or black. Eyes grey, margins reddish, ocelli red. Tip of labium black. Mesoscutum with four longitudinal light brown stripes; thorax brown ventrally. Forewing with semitransparent membrane bearing well defined dark brown pattern as in Fig. 5 View FIGURES 1 – 6 , forming a narrow irregular band along apical wing margin; veins ochreous; surface spinules whitish. Hindwing whitish, semitransparent; veins C+Sc and R+M+Cu ochreous. Metacoxa brown, metafemur ochreous. Abdomen reddish yellow dorsally, terminalia light brown. Head and thorax dorsally ( Fig. 1 View FIGURES 1 – 6 ) densely, and thorax laterally sparsely covered in powdery white waxy secretions.

Structure. Head dorsally, thorax dorsally and laterally, and abdomen ventrally covered in long conspicuous setae. Genal processes 0.5–0.6 times as long as vertex along mid-line, asymmetrical, obliquely truncate apically, outer margin, in dorsal view, strongly curved, inner margin almost straight, curved only at base, apex subacute ( Figs 1, 2 View FIGURES 1 – 6 ). Antenna 0.7–0.8 times as long as head width. Forewing ( Fig. 5 View FIGURES 1 – 6 ) 2.6–2.7 times as long as head width, 2.4–2.5 times as long as wide, widest in the middle; fore margin relatively evenly curved; surface spinules irregularly spaced and variable in shape and size. Metatibia 0.7–0.8 times as long as head width. Male terminalia as in Figs 7–9 View FIGURES 7 – 12 ; proctiger, in profile, produced posteriorly, widest in basal third; paramere clavate, weakly dilated in apical third, apex blunt, inner face densely covered in long, thick setae; inner margin of basal segment of aedeagus, in profile, lacking thorn-like tubercle in the middle of the straight part. Female terminalia as in Figs. 10, 11 View FIGURES 7 – 12 , cuneate, proctiger 0.4–0.5 times as long as head width, dorsal margin, in profile, concave, apex subacute; subgenital plate 0.8 times as long as proctiger, ventral margin with distinct angle in the middle.

Measurements (1 ♂, 1 ♀, in mm). Head width 0.49–0.51, antenna length 0.36, forewing length 1.30–1.36, metatibia length 0.39–0.41, male proctiger length 0.21, paramere length 0.20, female proctiger length 0.43.

Fifth instar immature. Colour. Dorsal sclerites and wing pads light ochreous, membranes whitish. Eyes greyish red. Antennal tip brown. Bacteriome discernable at abdominal base as reddish patch.

Structure. Body ( Fig. 13 View FIGURES 13 – 16 ) 1.2–1.3 times as long as broad. Antenna ( Fig. 12 View FIGURES 7 – 12 ) 3-segmented, segment 2 with 1 lanceolate seta, segment 3 with each a lanceolate seta near the two basal rhinaria; antenna 0.5 times as long as forewing pad. Humeral lobe of forewing pad short, reaching anteriorly posterior eye margin, blunt; outer margin of forewing pad weakly curved, bearing a few large and a few small lanceolate setae. Margin of abdomen with 22+22 to 25+25 lanceolate setae along caudal plate and 2+2 lanceolate setae cephalad of caudal plate. Caudal plate broadly rounded posteriorly, 0.6–0.7 times as long as wide. Outer circumanal ring consisting of a single row of pores 0.3 times as broad as caudal plate, distance from anterior to posterior margin of circumanal ring longer than distance from its posterior margin to that of caudal plate ( Fig. 14 View FIGURES 13 – 16 ).

Measurements (1 specimen, in mm). Body length 1.33; length of antennal segment 3 0.29; forewing pad length 0.57; caudal plate length 0.37.

Etymology. Named after its host plant Teucrium .

Distribution. Israel.

Host plant. Teucrium capitatum L. ( Lamiaceae ).

Discussion. Diaphorina teucrii sp. nov. differs from other congeners in the combination of the shape of genal processes, forewing shape and colour pattern, and male and female terminalia in the adult as well as number of lanceolate setae on antenna and abdominal margin and the number of pores on the circumanal ring in the immature. The new species resembles the palaearctic Diaphorina chobauti Puton from which it differs as indicated in the key given below.
