Diagnosis. Surface spinules fully covering cells r 1, r 2, m 1, m 2, cu 1 and cu 2; covering cells up to veins apically. Paramere, in lateral view, clavate, strongly expanded apically; apex irregularly straight; sclerotised ridge in most of posterior half. Aedeagus complex unipartite; in lateral view, ventral process with apical expansion larger than dorsal lobe.

Description. Colouration. Body with white striped-pattern; variation: mesopraescutum with lateral stripes fused to lateral spots on posterior margin; mesoepisternum with markings inconspicuous. Head and thorax pale orangeyellow, light yellow to yellow; genal process light straw-coloured to white. Eye grey to dark red; ocelli colourless to orange. Antenna light yellow, segments 1–2 slightly darker. Clypeus concolorous or slightly lighter than head, slightly lighter medially and slightly darker along edges; rostrum light yellow to light orange-yellow. Thorax with margins of sclerites slightly darker. Mesopraescutum rarely with posterior half irregularly coloured. Forewing yellowish, yellow around Cu 1b and seldom around M 3+4 and Cu 1a and slightly on M 1+2; veins light yellow; pterostigma concolorous with veins. Hindwing colourless. Fore- and midleg yellow, sometimes with tarsi slightly darker, hindleg light yellow. Abdomen light yellow to pale orange-yellow; intersegmental membranes light straw-coloured; spiracular sclerites concolorous with tergites. Male terminalia concolorous with abdomen, paramere and subgenital plate sometimes slightly darker. Female terminalia concolorous with abdomen, darker apically.

Structure. Body length ♁ 2.5–2.6 mm (2.55± 0.01 mm), ♀ 2.5–2.8 mm (2.68± 0.09 mm) (2 ♁, 4 ♀). Genal pro-cess ( Fig. 150View FIGURES 148–162) expanded, evenly or irregularly narrowing towards broadly rounded apex, 0.5–0.7 times as long as vertex along midline. Antenna 2.4 times as long as head width; longest terminal seta slightly shorter than segment 10. Apical labium segment 0.1–0.2 times longer than head width and 0.1–0.7 times longer than median segment. Forewing ( Fig. 180View FIGURES 173–182) 2.9–3.0 times as long as head width, 2.2–2.3 times as long as wide, obovoid or suboval, narrowly or broadly rounded apically; vein M+Cu 1 0.3–0.4 times as long as Cu 1; ratio a/b 1.7–2.0; ratio c/d 0.8–0.9; ratio e/f 0.5–0.7. Surface spinules distinctly spaced, forming rhomboids ( Fig. 38View FIGURES 38–43), sometimes densely spaced in cell r 1, forming irregular groups somewhat separated from each other ( Fig. 41View FIGURES 38–43); fully covering cells r 1, r 2, m 1, m 2, cu 1 and cu 2; leaving spinule-free spaces along veins ( Fig. 42View FIGURES 38–43), covering cells up to veins apically ( Fig. 43View FIGURES 38–43). Radular spinules sometimes present in r 2 but inconspicuous. Metatibia 0.6–0.7 times as long as head width.

Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with short, weakly tapered, weakly down-curved posterior lobe. Paramere, in lateral view ( Figs 244View FIGURES 238–246 ‾246) 0.7–0.8 times as long as proctiger; clavate, strongly expanded apically; anterior margin expanding in apical third, irregularly concave basally; posterior margin expanding in apical third, weakly to strongly convex in basal two thirds; apex irregularly straight, with sclerotised ridge in most of posterior half ( Fig. 245View FIGURES 238–246); inner surface ( Fig. 245View FIGURES 238–246) covered with long setae, longer basally and along posterior margin, with row of thick setae along apical anterior margin, several thick setae below sclerotised ridge, and group of stout setae on apical posterior margin; in dorsal view ( Fig. 300View FIGURES 283–312), sclerotised ridge irregularly straight, bearing posterior tooth. Aedeagus ( Fig. 246View FIGURES 238–246) complex unipartite; in lateral view, dorsal lobe subtriangular; ventral process weakly upturned, with apical expansion larger than dorsal lobe, irregularly globular, bearing long, conical tubercle.—Female ( Fig. 330View FIGURES 325–330). Proctiger, in lateral view, 1.0 times as long as head width; dorsal outline weakly concave distal to circumanal ring, apical extension sinuous, apex straight to slightly upturned, smoothly transversally truncate to obliquely rounded; circumanal ring 0.4 times as long as proctiger. Subgenital plate, in lateral view, 0.6 times as long as proctiger; apex well-developed; ventral outline almost straight to slightly sinuous, sometimes slightly notched subapically; covered with medium long setae in median third and ventrally throughout, short and medium long setae in apical third, long setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view ( Fig. 360View FIGURES 343–362), lateral margins evenly, strongly narrowing at about half towards narrow, rounded apex.

Measurements (in mm) (2 ♁, 3 ♀). HW ♁ 0.64–0.70 (0.67±0.04), ♀ 0.65–0.66 (0.66±0.01); AL ♁ 1.55–1.65 (1.60±0.07), ♀ 1.53–1.56 (1.55±0.02); LAB2 ♁ 0.17–1.50 (0.84±0.94), ♀ 0.15–0.17 (0.16±0.01); LAB3 ♁ 0.10, ♀ 0.10; FL ♁ 1.84–1.99 (1.91±0.1), ♀ 1.97–2.01 (1.99±0.02); TL ♁ 0.42–0.46 (0.44±0.03), ♀ 0.42–0.44 (0.44±0.01); MP 0.27–0.30 (0.29±0.02); PL 0.22; DL 0.26; FP 0.62–0.64 (0.63±0.01).

Distribution. Brazil (Bahia) (Tavares 1920, 1922, as ‘Psyllídeo’; Crawford 1925, as Psylla itaparica  ; Costa Lima 1942). New state record for Brazil: Paraná, Santa Catarina.

Host-plant. Sophora tomentosa  L. (Leguminosae, Papilionoideae  , Sophoreae  ).

Habitat. Coastal vegetation, close to the beach.

Comments. Mitrapsylla itaparica (Crawford)  resembles M. cujabensis  sp. nov., M. soror  sp. nov. and M. villosi  sp. nov., but differs from them in the surface spinules fully covering all cells and the paramere, in lateral view, with apex irregularly straight (rather than weakly or strongly indented) and anterior margin never expanded dorsally. See comments under M. soror  sp. nov.
