Dorsum dark brown. Eye brown with posterior internal region velvety black. Frontal plate bright black. Clypeus black, anteclypeus orange brown. Bucculae black. Labrum and rostrum orange brown. Antennomeres I-II orange brown; III-IV brown. Pronotum dark brown, with a pair of irregular bluish gray markings laterally on anterior margin, a pair of small rounded bluish gray markings near midline, and a pair of oblique bluish gray markings near lateral margins; lateral margins and center of posterior margin orange brown. Scutellum black. Forewing black; clavus with proximal and distal irregular bluish gray markings; corium with small proximal irregular bluish gray markings and distal subcircular bluish gray mark; embolium with two irregular spots on inner portion, four larger lateral bluish gray markings, and external margin yellowish or orange; membrane with a pair of lateral bluish gray markings and several irregular spots distally. Venter of body dark brown to black, covered by grayish pubescence on thorax. Margins of acetabulae lighter. Foreleg with coxae black, femur and tarsus dark brown, trochanter and tibia yellowish; middle and hind legs with coxae and tarsi brown, trochanter, femur, and tibiae yellowish.
Body oval-shaped, covered by small shining setae. Head with large eyes. Vertex dull. Frontal plate with transverse ridges along entire length; anterior portion with short low median carina; distinct longitudinal carinae adjacent to internal margins of eyes. Antennomeres I-II distinctly wider than III-IV. Rostrum elongated, surpassing middle coxae. Anterolateral angles of pronotum obtuse; anterolateral depression deep, large; lateral margins oblique, posteriorly divergent; posterior margin trisinuous; collar and disc punctate, sides impunctate. Scutellum and forewing, except membrane, weakly punctate; membrane with seven closed cells, with bright setae on veins. Legs covered by light setae, tibiae with long stout setae, more numerous on hind leg. Genitalia asymmetric; process of pygophore elongate, with apex sharp; right paramere with body sinuous and apex hook-shaped and obtuse (Plate 1, Figs. 1–4).
Macropterous female (Plate 1, Figs. 5–6). BL—6.00; BW—2.92; HL—0.90; HW—1.50; ANT I—0.15; ANT II—0.30; ANT III—0.30; ANT IV—0.36; EYE—0.60; INT—0.45; OI—0.86; PL—2.75; PW—3.40.
Color and structure very similar to male, except: pronotum with midposterior portion orange. Clavus without distal irregular bluish gray markings; corium with two parallel subcircular bluish gray markings; embolium without irregular spots on internal portion. Frontal plate and clypeus bright black. Anteclypeus dark brown. Antennomeres I-IV brown. Vertex smaller.
Type-material. BRAZIL: Piauí—Piracuruca, Parque Nacional de Sete Cidades, Olho d'água dos milagres, 04°05'32''S / 41°40'48''W, 180 m a.s.l., 8.II.2013, (A.P.M. Santos & D.M. Takiya): 1 macropterous male [HOLOTYPE] (CZMA). Piracuruca, Parque Nacional de Sete Cidades, Cachoeira do Riachão, 04°06'28''S / 41°40'13''W, 9.II.2013, (A.P.M. Santos & D.M. Takiya): 1 macropterous female [PARATYPE] (CZMA).
Distribution. Known from two water bodies on Sete Cidades National Park in northeastern Brazil (Fig. 7).
Etymology. Named in honor of Dr. Allan P. M. Santos, one of the collectors of the specimens.
Comments. Ochterus perbosci (Guérin-Méneville, 1844) differs from O. santosi sp. nov. by the presence of sharp projections (rarely underdeveloped) on the pronotum and series of yellowish spots along the exterior margin of the hemelytra. Ochterus santosi sp. nov. is distinguished from O. parvus Schell, 1943 by the dark dorsum, body length greater than 3.30 mm, and apex of right paramere without projections. Ochterus santosi sp. nov. differs from O. americanus (Uhler, 1876) by the right paramere not extended beyond the apex of the genital capsule and body length less than 6.50 mm; from O. aeneifrons surinamensis Nieser, 1975 by the black scutellum without bluish gray spots; and finally from O. tenebrosus Nieser, 1975 by the strong gray spots along the dorsum and the distinct longitudinal carinae adjacent to the inner margin of the eyes.
