Material examined.

Holotype: ECUADOR, Orellana: Yasuni Research Station, 228m, 0.67°S, 76.40°W; 1-5 Dec 2009, D. Forero, EC09_L5, Berlese. MGPhD-E369. Male, Brachypterous.


Body dark brown to blackish; cephalic spines long and thin; anterior edge of paranota not reaching the eyes; discoidal area biseriate and subcostal area irregularly quadriseriate.


Body oval; mostly dark brown, or blackish; collar, paranota, and lateral edge of costal area and hemelytral membrane white; tip of cephalic spines, scape and pedicel light brown (basi- and distiflagellomere missing); occipital spines lighter in color.

Head with numerous, small, curved hairs and seven spines: clypeal pair non-erect; jugal spine slightly erect; frontal pair divergent; occipital pair short, strongly divergent; frontal and occipital pairs erect. Antenniferous processes spine-like, projected forward, subequal to scape in size. Scape slightly longer than pedicel, basi- and distiflagellomere missing. Interocular distance almost three times width of eye. Rostrum light brown, surpassing posterior margin of metanotum. Bucculae white, areolate; open in front, with an acutely projected antero-inferior edge; widely open posteriorly, width same as anterior region.

Pronotum mostly flat, posterior projection absent, leaving small portion of scutellum exposed. Median carinae whitish, uniseriate, composed of small cells, extending throughout pronotum. Collar biseriate and slightly elevated. Paranota slightly reflexed, broad, with four cells at widest part; anterior edge not reaching eyes. Sternal membranes whitish, areolate, uniseriate, and concave. Hemelytra ovate, inner border conspicuously concave posteriorly; clavus large, 2-seriate at widest part, inner vein straight, outer edge convex; discoidal area biseriate; cubitus whitish posteriorly after R+M junction; radius-media (R+M) white for most of length, raised, stout; subcostal area mostly 3-seriate, four rows of areolae at widest part; costal area wide, with as many as six rows of areolae, widening posteriorly; membrane shortened (specimen brachypterous); hypocosta dark brown, areolate anteriorly, but light brown, rim-like for most of length, ending at membrane. Scent-gland opening round, auricular-like, dark. Legs light brown, coxae and trochanters stout; longer, spine-like setae at posterior edge of tibiae; second tarsi long and slender. Claws long, slender, well developed.

Pygophore conspicuously narrower than abdomen; dorsal rim strongly curved, almost sinuous, forming small depressions laterally and dorsally. Paramere stout at base, abruptly but consistently narrowing to very slender tip, pronounced elbow at base.

Measurements: body length, 2.01; body width, 1.19; head length, 0.39; head width, 0.31; interocular width, 0.18; pronotum length, 0.35; pronotum width, 0.86; scape length, 0.06; pedicel length, 0.05.


Of the three known species of Zetekella  , Z. henryi  sp. n. is more morphologically similar to Z. zeteki  because of the broader paranota and hemelytra, and the long clypeal, jugal and frontal cephalic spines. It differs from Z. zeteki  by the thinner cephalic spines, the anterior edge of paranota not reaching the eyes, the narrower discoidal and subcostal area, and by its color pattern.


This species is named after the outstanding heteropterist and dear friend Thomas Henry, on the occasion of his 70th birthday and his remarkable career and countless contributions to the study of Heteroptera  .
