Description. Measurement [mm] as in table 1.

Male: Figs. 1 A–D, 2 A–G, 3 A–F, 4. Head dark brown to black, with big yellow spots over antennal socket (the spots may touch).Antennal sockets, anteclypeus and proximal part of labrum yellow ( Figs. 1 B, D ). Compound eyes dark; intraocular space large; ocelli not visible. Antennae short, reached at most half the body. Scapus, and meriston longer than wide, glossy; following 10–13 segments near square-shape, dark brown and glossy, nearly without se- tae; next 21–24 segments smaller, pale brown, dull, densely cover by small setae.

Pronotum big, yellowish-red, very obvious, front and lateral parts bordered with elevated narrow strip; surface between margin and pronotal disc sparsely cover relatively big pits; elevated border of pronotal disc brick red, inner part of disk black, but centrally with four big near circled-shape, elevated, yellowish spots, two at the bottom smaller than two at the top ( Figs. 1 A, C ).

Legs dark brown to black, glossy; trochanters and adjacent parts of coxae, and surrounding of genicular joints yellowish-brown; tibiae short, armed with long and strong spines, especially on outer ridge; arolia and pulvilli welldeveloped, yellow; claws simple and symmetrical. Front femur type C1.

Tegmina broad, coriaceous, yellowish-brown; left tegmen overlapped largely right one ( Figs. 1 A, C ); vena- tion very dense with number of cross-veins; anal field separated by a conspicuous claval furrow. Membranous hind wings relatively short, greyish-brown except for pale base, veins generally pale brown; venation plentiful with numerous cross-veins; some veins associate and subsequently diverge; anterior part of wings darker as posterior one ( Fig. 4 ); anal lobe folded at rest between CuP and 1A.

Abdomen dark brown to black, glossy; T2–T7 with yellowish band on lateral and distal margins; S4–S5 cen- trally with yellowish irregular spots ( Figs. 2 A, B ). Supra-annal plate symmetrical, distal part pale, posteriorly with a superficial V-shaped incision in the middle. Cerci ±10-segmented, on its bases narrow pale-brown line; ventral side very densely haired, dorsal side plain ( Figs. 2 C, E ). Subgenital plate slightly asymmetrical ( Fig. 2 D ); styli small; pale plate around right stylus markedly bigger than left one and its distal margin concave ( Figs. 2 F, G ).

Genitalia ( Figs. 3 A–F).

Genital hook (L3’) with five inexpressive folds in the inner margin of membranous part.

Preputial spines very numerous, but mostly short (L2vm).

Female: Figs. 5 A, B . Very similar to male. Pronotum distally angustate; disc black with four simple unelevated circle spots, two at the bottom smaller than the two at the top; disc is not bordered by elevation ( Fig. 5 A ). Tegmina shortened, reaching to T7. Hind wings relatively short, but partly protruded from under tegmina. Supra-anal plate very similar to male. S6 longer as other sternites. Subgenital plate symmetrical, relatively short and broad; distal border rounded, but opposite to cerci are indistinctive concave cuts ( Fig. 5 B ).

Etymology. The new species is named in honour of Dr. Giovanni Onore, missionary, entomologist, President of the Otonga Foundation in Ecuador and first collector of this species.

Distribution. Ecuador (Sucumbios Province) ( Fig. 12 ).

Remarks. We assume that described paratype represents the female of the species Quadrihormetica onorei . This specimen comes from same locality as holotype male (Lumbaqui), proportionally corresponds to described male. Shape of pronotum and four yellow spots on pronotum are similar to male and the drawing on head is almost identical as in male.

A very similar view of female pronotum as described here in case of Quadrihormetica female was illustrated based on specimens from Colombia (1 ♂, Antioquia: Medellin and 1 ♀, Cundinamarca: Mesitas del Colegio) by Salazar (2001). No other description was mentioned. Although Salazar (2001) assigned these two females into the genus Hormetica they might belong to the new, here described, genus Quadrihormetica. Until now, two species from the genus Hormetica ( H. marmorata Saussure, 1869 and H. apolinari Hebard, 1919 ) and two related species of the genus Lucihormetica ( L. subcincta (Walker, 1868) and L. verrucosa (Brunner v. W., 1865)) were documented from Columbia. Females of above mentioned species have different view of pronotum, likewise all other species from genera Hormetica and Lucihormetica .
