Crown ( Fig. 1 ) with a black median macula at anterior margin, three pairs of brown maculae: first pair larger, adjacent to anterior margin, closer to midline than eyes, second pair elongated anterior and adjacent to ocelli, third pair smaller, adjacent to outer posterolateral margin of ocelli.

Pronotum ( Fig. 1 ) with a pair of black spots behind eyes; disk and apical half with several dark punctures. Proepimeron ( Fig. 3 ) with a black stripe below pronotal carina. Mesonotum ( Fig. 1 ) with a pair of large dark brown maculae adjacent to posterior margin of pronotum and a pair of small median dark brown spots near scutoscutellar suture. Forewing ( Fig. 4 ) dull yellow; clavus and apical portion of wing mottled with small brown maculae; region between anal vein 1 and claval suture, brachial cell, and costal region with larger dark brown mottled maculae; veins yellow, apex of anal veins and crossveins dark brown; appendix with a narrow brown basal band and a large brown macula near apex. Legs dull yellow with dark brown areas, metatibia with cucullate bases of setae dark.

Description. Head ( Fig. 1 ), in dorsal view, crown with median length approximately one-third of interocular width, transocular width eight-tenths of pronotal humeral width, texture with irregular transverse striae, except oblique between ocelli; anterior margin rounded, slightly projected over the anterior margin of the eyes; ocelli closer to posterior than anterior margin and closer to midline than to compound eyes. Head ( Fig. 2 ), in ventral view, slightly wider than tall; frons 1.6 times longer than wide, dorsal region with thin irregular transverse striae; frontogenal suture distant from eye margin 2 times the diameter of the antennal scape; antennal ledge carinated and oblique, slightly extended over frons; clypeus 1.6 times longer than maximum width, lateral margins straight and parallel, slightly divergent apically, apex emarginated medially. Head ( Fig. 3 ), in lateral view, with transition crown-face defined, thin, with transverse striae weakly defined. Pronotum ( Fig. 1 ), in dorsal view, lateral margins longer than length of eye. Forewing ( Fig. 4 ) with clavus slightly coriaceous; outer discal cell with inner apical accessory vein; m-cu1 crossvein closer to the m-cu2 crossvein than to the R+M fork, m-cu2 equidistant from r-m1; appendix well developed, wider than first apical cell width. Metatarsomere I pecten with 6–8 platellae. Metatarsomere II with pecten with 3 platellae and a spine on each side.

Male terminalia. Sternite VIII ( Fig. 5 ), in ventral view, subtrapezoidal; 1.4 times wider than long; lateral margins straight, slightly converging towards apex; posterolateral angles rounded; posterior margin almost straight. Valve ( Fig. 6 ), in ventral view, 2.6 times wider than long; posterior margin deeply excavated medially. Pygofer ( Fig. 7 ), in lateral view, subtriangular; high at base and narrowing towards apex; 1.2 times longer than high; posterodorsal margin slightly excavated preapically; posteroventral margin rounded; macrosetae dispersed medially and apically; apex rounded; in dorsal view ( Fig. 8 ), posterodorsal margin with a long, slightly sclerotized subtriangular projection directed internally. Anal tube membranous. Subgenital plate ( Fig. 7 ), in lateral view, long, almost reaching apex of pygofer; in ventral view, ( Fig. 9 ), elongated and ligulate; 4.5 times longer than maximum width; outer lateral margin almost straight, with small setae, on apical half; inner lateral margin widely rounded; apex narrowly rounded. Connective ( Fig. 10 ), in dorsal view, transverse; with two small projections on posterior margin; stem absent; dorsal keel absent. Style ( Fig. 10 ), in dorsal view, with outer lobe rounded; blade abruptly curved laterally posterior to outer lobe; in lateral view ( Fig. 11 ), blade sinuous, slightly constricted preapically; ventral margin serrated; apex rounded with dorsal preapical spiniform process. Aedeagus ( Figs 12, 13 ) with preatrium underdeveloped; dorsal apodeme developed, dorsal margin slightly straight, lateral margins projected laterally; atrium with a pair of elongated processes, each as long as shaft, strongly expanded dorsally at middle third, dorsal margin subapically excavated, anteriorly curved near apex, apex acute; shaft elongated, thin, and tubular, symmetrical, basal portion, in lateral view, U-shaped, apical portion expanded laterally with a pair of short lateral processes, each less than onefifth length of shaft, ventrally directed, acute at apex.

Female terminalia. Female unknown.

Etymology. The new species is named in honor to a friend and harvestmen specialist Andrés Felipe García Rincón, who participated in one of the expeditions to Parque Nacional do Itatiaia. He left us too early, but left a legacy for science and the world of harvestmen.

Material examined. Holotype male: “ Brazil. RJ. Itatiaia. PNI\ 01.XI.2014, S22°25’59.6’’ W\44°37’39.7’’, 1280m, Ponto\ 2, Monteiro et al.” ( DZRJ) . Paratypes: 1 ♂, “with the same label data as holotype ( DZRJ)” . 1 ♂, “ Brazil, RJ, Itatiaia, PNI\ 04.IX.2014, S22°25’59.6” W\44°37’39.7”\ 1280m, Ponto \ 2, Monteiro et al.” ( MNRJ). 1 ♂, “ Brazil, RJ, Itatiaia, PNI\ 04.X.2014 \ S 22°25’59.6’’ W\ 44°37’39.7’’, 1280m, Ponto\ 2, Monteiro et al.” ( MNRJ) .

Taxonomic notes. Curtara (Curtara) andresi sp. nov. resembles the type-species Curtara (Curtara) samera DeLong & Freytag, 1972 by its pronotum with dark punctures ( Fig. 1 ); forewing outer discal cell with inner apical accessory vein ( Fig. 4 ); subgenital plate with apical portion narrowed ( Fig. 9 ); connective ( Fig. 10 ) transverse; and aedeagus shaft with a pair of apical processes ( Figs 12, 13 ). However, Curtara (Curtara) andresi sp. nov differs from Curtara samera and other species of the genus by the following set of characteristics: pygofer with posterodorsal margin with a long, slightly sclerotized subtriangular projection ( Fig. 8 ); style with blade abruptly curved laterad, with ventral margin serrated and apex rounded with dorsal preapical spiniform process ( Figs 10, 11 ); and aedeagus with a pair of elongated atrial processes, expanded at middle third and dorsal margin subapically excavated ( Fig. 12 ).

Curtara (Curtara) andresi sp. nov. was collected at PNI only at 1,260 m a.s.l.
