Published records in Israel. CN (Burckhardt et al. 2015).
Host plant. Teucrium capitatum (Lamiaceae).
Eremopsylloides vicinus Spodek & Burckhardt, sp. nov. (Figs. 25‒31, 33)
Material examined. Holotype ♂, Israel: AV: Hazeva Wadi Shezaf, 5‒12.iv.2000, Malaise trap (N.D Springate) (SMNHTAU, dry mounted). Paratypes. Israel: AV: 1 ♂, 5 ♀, same data as holotype (SMNHTAU and NHMB, dry and slide mounted).
Description. Adult (Fig. 25). Colour. Orange-brown with dark greyish brown pattern. Vertex ochreous with dark pattern along margin and in the middle. Genae and clypeus brown. Antennal segments 3–7 yellow, segments 1, 2, 8–10 and apices of segments 4 and 6 dark brown. Pronotum dark with two whitish spots laterally; mesopraescutum yellowish with two reddish dark brown patches antero-laterally and two dark greyish patches posteriorly; mesoscutum dark brown with three yellow longitudinal lines on either side; mesoscutellum yellow with a dark spot antero-medially and dark margins laterally and posteriorly; metascutum yellow with almost black spot anteriorly and reddish brown patch posterriorly; metascutellum dark with yellow spots. Forewing (Fig. 28) whitish, opaque; brown, well defined dots present in all cells, denser and confluent apically, leaving whitish areas free along the wing margin in cells r2, m1, m2, cu1 and cu2; apex of clavus brown; veins concolourous with membrane. Hindwing whitish, semitransparent, anal cell partly brown. Legs brown, tarsi dirty whitish. Abdominal sclerites brown to dark brown, membranes reddish.
Structure. Head inclined at about 45° from longitudinal body axis; slightly narrower than mesoscutum. Body surface mat, finely punctured, with indistinct microscopic setae (hardly visible at 80 x magnification). Vertex (Fig. 29) subtrapezoidal, flat with indented foveae; evenly curved down to genae anteriorly; frons small, almost entirely covered by anterior ocellus. Antenna (Fig. 26) 10-segmented, filiform, slightly longer than head width, with a subapical rhinarium on each of segments 4, 6, 8 and 9; segment 3 slightly longer than segments 4–6 together; segments 4, 6, 8 and 9 slightly wider apically than basally; segment 10 narrower and short that segment 9; longer terminal antennal seta slightly longer than, shorter one about as long as segment 10 (Fig. 27). Clypeus flattened, pyriform. Propleurites broad, suture oblique, proepimeron small triangular, proepisternum large square. Forewing (Fig. 28) oval, apex broadly rounded; costal break developed; pterostigma short, broad, at base about as wide as adjacent part of cell r1; veins R and M+Cu subequal in length; Rs almost straight, in the middle weakly curved towards fore margin; cell m1 larger than cell cu1; branches of veins M and Cu longer than their respective stems; surface spinules present in all cells, distinct on dark patches otherwise finer or indistinct; densely spaced. Hindwing bearing (1–2) + (3–6) costal setae distal to costal break which are clearly grouped; veins R+M developed. Hind leg with big metacoxa bearing a large, pointed meracanthus; metatibia without genual spine, bearing an open crown of 5–6 more or less evenly spaced sclerotised apical spurs; metabasitarsus with two lateral sclerotised spurs. Male and female terminalia as in Figs 30, 31, 33. Male proctiger tubular, posterior margin straight, sparsely covered in medium long setae in apical two thirds. Subgenital plate, in profile, elongate, ventral margin with distinct angle in the middle; sparsely beset with moderately long setae in the middle. Paramere, in profile, broadly lamellar, narrowing in apical half, evenly rounded apically; outer face with moderately long setae in posterior half; inner face bearing peg setae along the posterior half. Distal portion of aedeagus long, slender, with flat apical inflation; sclerotised end tube of ductus ejaculatorius moderately long, strongly sinuous. Female terminalia cuneate. Dorsal margin of proctiger almost straight, apex rounded; covered with medium long setae. Circumanal ring small, oval, with a single row of elongate pores. Subgenital plate cuneate, ventral margin almost straight, densely covered with long setae. Valvula dorsalis cuneate, weakly curved; valvula ventralis curved, lacking teeth.

Host plant. Unknown.
Comments. Eremopsylloides vicinus is most similar to E. fedtschenkoi (Löw) in the oval, dotted forewing. It differs from the latter in the narrower forewing which bears whitish dot-free areas along the wing margin in cells r2, m1, m2, cu1 and cu2; the brown spots at the apex of the forewing more confluent; the slightly more elongate male subgenital plate; the narrower paramere with less peg setae on the inner face (Figs. 31 and 32) and the shorter female terminalia (Figs. 33 and 34).
Etymology. This species is named from the Latin vicinus = neighbouring, in reference to its close resemblance to E. fedtschenkoi.
