LSID: urn:lsid:zoobank.org:act: 63917DDC-F24B-423D-8B89-4ADADCDDAFFD
Material examined. Holotype ♁, Brazil: Roraima, Pacaraima, along RR-174 from Pacaraima to São Marcos 20 km S of Pacaraima, 4.4033, -61.1483, 490–910 m, 15.iv.2015, roadside vegetation, Cassia ferruginea (D. Burckhardt & D.L. Queiroz), #162(4) (DZUP 215423, dry).
Paratypes. Roraima: 2 ♁, 1 ♀, same data as holotype (D. Burckhardt & D.L. Queiroz), #162(4) (NHMB, dry, slide mounted); 1 ♀, Amajari, Tepequém, outside village along road, 3.7783, -61.7217, 610 m, 5.iv.2015, planted trees (D. Burckhardt & D.L. Queiroz), #159(-) (NHMB, 70% ethanol); 3 ♁, Boa Vista, Embrapa, 2.7550, -60.7300, 80 m, 1–2.iv.2015, various experimental plantations, secondary scrub, Deguelia densiflora (D. Burckhardt & D.L. Queiroz), #151(3) (NHMB, 70% ethanol).
Diagnosis. Body light straw-coloured to light yellow, with faint striped-pattern. Paramere, in lateral view, lamellar; anterior and posterior margins subparallel, weakly sinuous; apex truncate, slightly directed posteriorly; in dorsal view, sclerotised ridge bearing small anterior, median and posterior tooth. Aedeagus complex unipartite; in lateral view, dorsal lobe obovoid; ventral process with apical expansion subequal in size with dorsal lobe, oval.
Description. Colouration. Body with faint striped-pattern; variation: parapterum and mesoepisternum lacking distinct striped-pattern. Body light straw-coloured to light yellow. Vertex sometimes whitish; genal process concolorous with head. Eye grey to red; ocelli colourless. Antenna yellow, segments 1–2 concolorous with head. Clypeus concolorous with body, slightly lighter medially; rostrum yellow. Thorax with margins of sclerites slightly darker. Forewing yellowish, yellow around Cu 1b and slightly around M 1+2, M 3+4 and Cu 1a; veins light yellow; pterostigma concolorous or slightly lighter than veins. Hindwing colourless. Fore- and midleg dark yellow with tarsi darker, hindleg light yellow. Abdomen; intersegmental membranes light straw-coloured; spiracular sclerites concolorous with tergites. Male terminalia light yellow. Female terminalia light yellow, brownish apically.
Structure. Body length ♁ 1.9 mm, ♀ 2.5–2.6 mm (2.55± 0.07 mm) (1 ♁, 2 ♀). Genal process (Fig. 153) ex-panded, irregularly narrowing towards broadly or narrowly rounded apex, 0.6 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 0.2 times longer than head width and 0.6 times longer than median segment. Forewing (Fig. 183) 2.7 times as long as head width, 2.4 times as long as wide, subobovoid, narrowly rounded apically; vein M+Cu 1 0.3 times as long as Cu 1; ratio a/b 1.7; ratio c/d 0.7; ratio e/f 1.0. Surface spinules covering apical two thirds of cell r 1, apical half of cell r 2, around radular areas of cells m 1, m 2 and cu 1, m 2 basally (much reduced), and most of cell cu 2; leaving spinule-free spaces along veins (Fig. 42). Radular spinules sometimes present in r 2 but inconspicuous. Metatibia 0.6 times as long as head width.
Terminalia. Male. Proctiger, in lateral view, 0.3 times as long as head width; with long, strongly tapered, strongly down-curved posterior lobe. Paramere, in lateral view (Figs 253 ‾255) 1.1 times as long as proctiger; lamellar; an-terior and posterior margins subparallel, weakly sinuous; apex truncate, slightly directed posteriorly; inner surface (Fig. 254) covered with long setae, with row of thick setae along apical anterior margin, group of thick setae below sclerotised ridge and on apical posterior margin; in dorsal view (Fig. 303), sclerotised ridge bearing small anterior, median and posterior tooth. Aedeagus (Fig. 255) complex unipartite; in lateral view, dorsal lobe obovoid; ventral process weakly upturned, with apical expansion subequal in size with dorsal lobe, oval, bearing long, conical tubercle.—Female (Fig. 333). Proctiger, in lateral view, 1.1 times as long as head width; dorsal outline weakly concave distal to circumanal ring, apical extension almost straight, apex straight, slightly obliquely rounded; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.5 times as long as proctiger; apex well-developed; ventral outline mostly straight, weakly expanded subasally; covered with medium long setae in median third, long setae ventrally throughout, short and medium long setae in apical third, longer setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view (Fig. 363), lateral margins unevenly, weakly narrowing towards slightly broad, subtruncate apex.
Measurements (in mm) (1 ♁, 1 ♀). HW ♁ 0.60; AL ♁ 1.46; LAB2 ♁ 0.16; LAB3 ♁ 0.10; FL ♁ 1.62; TL ♁ 0.38; MP 0.20; PL 0.22; DL 0.24; FP 0.73.
Etymology. From Greek ώχρα = ochre coloured, referring to its ochreous colour.
Distribution. Brazil: Roraima.
Host-plant. Unknown.
Habitat. Roadside vegetation, various experimental plantations, secondary scrub.
Comments. Mitrapsylla ochra sp. nov. resembles M. pallida sp. nov. in the pale body colour and the lamellar paramere in lateral view; but differs in the paramere anterior and posterior margins subparallel and less sinuate, with apex truncate (rather than irregularly rounded), the surface spinules covering cells up to veins in apical half of forewing (rather than leaving spinule-free spaces along veins), and the aedeagus with dorsal lobe indented submedially on dorsal outline.
