(Figs 116, 146, 176, 232 ‾234, 296, 326, 356, 376)
LSID: urn:lsid:zoobank.org:act: 97830469-07F2-40FB-B8BF-8E1BF7C44F10
Material examined. Holotype ♁, Brazil: Mato Grosso do Sul, Ponta Porã, Fazenda Mariana, Conflora, -22.0085, -55.5828, 590 m, 9.xii.2008 (D.L. Queiroz) (DZUP 215413, dry).
Paratypes. Mato Grosso do Sul: 2 ♁, 2 ♀, 12 immatures, same data as holotype (D.L. Queiroz) (DZUP, NHMB, dry, slide mounted, 70% ethanol).
Diagnosis. Paramere, in lateral view, clavate, weakly expanded apically; posterior margin relatively straight in basal two thirds, forming small lobe in apical third; inner surface lacking group of stout setae on apical posterior margin. Aedeagus complex tripartite; in lateral view, lateral lobule slightly shorter than dorsal lobule, irregularly rounded apically; membranous pouch small; ventral process strongly upturned, with apical expansion larger than dorsal lobe, oblong-oval.
Description. Colouration. Body with white striped-pattern. Head pale orange to yellowish-orange; genal process lighter than head. Eye grey to dark red; ocelli orange. Antenna yellow, segments 1–2 darker. Clypeus dark yellow, slightly lighter medially; rostrum dark yellow to yellowish-brown. Pronotum dark yellow to dark orange. Mesopraescutum dark yellow to dark orange, sometimes with posterior half irregularly coloured. Forewing yellowish, yellow around Cu 1b and slightly around rest of veins apically; veins light yellow to yellow; pterostigma concolorous or slightly lighter than veins. Hindwing colourless. Fore- and midleg dark yellowish, hindleg light yellow. Abdomen dark yellow to orange, sometimes darker ventrally; spiracular sclerites concolorous with sternites. Male terminalia irregularly light yellow. Female proctiger dark yellow, usually darker apically, subgenital plate light yellow to yellow.
Structure. Body length ♁ 2.3 mm, ♀ 2.5 mm (1 ♁, 1 ♀). Genal process (Fig. 146) expanded, irregularly nar-rowing towards subacute or narrowly rounded apex, 0.6 times as long as vertex along midline. Antenna 2.5 times as long as head width; longest terminal seta slightly shorter than segment 10. Apical labium segment 0.2 times longer than head width and 0.6 times longer than median segment. Forewing (Fig. 176) 2.8 times as long as head width, 2.4 times as long as wide, obovoid, narrowly rounded apically; vein M+Cu 1 0.4 times as long as Cu 1; ratio a/b 1.5; ratio c/d 0.8; ratio e/f 0.6. Surface spinules moderately spaced, forming rhomboids (Fig. 39); fully covering all cells; leaving spinule-free spaces along veins (Fig. 42). Metatibia 0.7 times as long as head width.
Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with long, blunt or weakly tapered, weakly down-curved posterior lobe. Paramere, in lateral view (Figs 232 ‾234) 0.8 times as long as proctiger; cla-vate, weakly expanded apically; anterior margin weakly sinuous; posterior margin relatively straight in basal two thirds, forming small lobe in apical third; inner surface (Fig. 233) covered with long setae, longer along posterior margin, with row of thick setae along apical anterior margin, several thick setae below sclerotised ridge and on apical posterior margin; in dorsal view (Fig. 296), sclerotised ridge bearing sclerotised posterior tooth. Aedeagus (Fig. 234) complex tripartite; in lateral view, dorsal lobe with slightly flattened, elongate median lobule; lateral lobule slightly shorter than median lobule, irregularly rounded apically; membranous pouch small; ventral process strongly upturned, with apical expansion larger than dorsal lobe, oblong-oval, bearing long, blunt tubercle.—Female (Fig. 326). Proctiger, in lateral view, 1.0 times as long as head width; dorsal outline moderately to strongly concave distal to circumanal ring, apical extension sinuous, apex moderately upturned, smoothly obliquely truncate; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.6 times as long as proctiger; apex well-developed; basal half of ventral outline strongly expanded, apical half almost straight; covered with medium long setae in median third, ventrally throughout and in apical third, long setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view (Fig. 356), lateral margins evenly, strongly narrowing at half, apical third narrow, weakly narrowing towards rounded apex.
Measurements (in mm) (1 ♁, 1 ♀). HW ♁ 0.66; AL ♁ 1.64; LAB2 ♁ 0.16; LAB3 ♁ 0.10; FL ♁ 1.88; TL ♁ 0.48; MP 0.26; PL 0.22; DL 0.30; FP 0.60.
Etymology. Dedicated to Susan E. Halbert for her valuable contribution of material.
Distribution. Brazil: Mato Grosso do Sul.
Host-plant and habitat. Unknown.
Comments. Mitrapsylla halbertae sp. nov. resembles M. domahovskii sp. nov. in the paramere, in lateral view, with posterior margin forming a small lobe in apical third; but differs in the paramere bearing a group of stout setae on apical posterior margin, and the aedeagus, in lateral view, with dorsal lobe bearing elongated membranous pouch (rather than small) and ventral process oval (rather than oblong-oval).
