(Figs 1–14)

Measurements (in mm). Mean ± SD (range) of 8 males / 14 females. Total length: 11.1 ± 1.25 (9.5–12.6) / 11.1 ± 1.11 (9.6–12.7); length of pronotum: 1.8 ± 0.22 (1.5–2.1) / 1.9 ± 0.16 (1.6–2.1); width of pronotum: 2.9 ± 0.31 (2.6–3.3) / 2.9 ± 0.26 (2.6–3.4); length of forewing: 9.4 ± 1.18 (7.8–10.6) / 9.3 ± 1.02 (7.8–10.6); width of forewing: 3.4 ± 0.35 (2.9–3.9).

Diagnosis. Head, pronotum, scutellum, and basal third of forewing, red; median and apical third of forewing, black.

Description. Head (Figs 1–5) red. Postclypeus not laterally inflated, obtusely and regularly rounded in profile; medial carina and lateral horizontal ridges distinct; antenna black, third antennal segment short, with subcylindrical basal body and short arista. Rostrum extending to level of mid coxae; third segment black. Eye black. Pronotum and scutellum (Figs 1–5) red. Forewing (Figs 1–2) with basal third red, median and apical third black; apical third reticulated; slender; slightly less than 2.8 times width at level of clavus apex; M and Cu1 fused at basal third; A1 vein distinct and percurrent, A2 obsolete. Wing with Cu1 thickened at base. Hind tibia with basal spine very small, distal large, with 10 distinct apical spines in one row; hind metatarsus with nine distinct apical spines in one row; subungueal process present. Abdomen dark brown; legs red, except prothoracic tibia and tarsi black.

Male subgenital plate (Fig. 6) more than twice as long as basal width, apex acute. Paramere (Figs 10–11) simple, slender; apical and dorsal setae very long; apex narrowly rounded; apical spine heavily sclerotized, directed posteroventrally. Aedeagus shaft (Figs 8–9) upright, lateral and posterior surfaces covered with tooth-like spines extending throughout apical 2/3; small process ventrally at apex; gonopore apical.

Female first valvula of ovipositor (Figs 12, 14) with one basal ventral curved spoon-like process. Second valvula of ovipositor (Fig. 13) long.

Type material. Holotype male: “ ECUADOR: Morona / Santiago Province / 5 km south of Macas / 02°19´S, 78°07´W // 18 December 1995 / E.S. Ross, collector / California Academy Sci.” (CASC) . Paratypes: 3 males (MCTP 57440, DZUP, BMNH) and 7 females (1- MCTP 57441, 1 - DZUP, 1- BMNH, 4 CASC), same data as holotype; 4 males, “ ECUADOR: Napo Prov. / 20 km E Puerto Napo, / Alifiahui, elev. 450 m / 1°00´S, 77°25´W // December 1995 / E.S. Ross, collector / California Academy Sci.” (MCTP 57442, DZUP, BMNH, CASC) ; 6 females “ ECUADOR: Napo Prov. / 20 km E Puerto Napo, / Alifiahui, elev. 450 m / 1°00´S, 77°25´W // December 1995 / E.S. Ross, collector / California Academy Sci.” (1- MCTP 57443, 1 - DZUP, 1- BMNH, 3 CASC) ; 1 female “ ECUADOR: Napo Prov. / 20 km E Puerto Napo, / Alifiahui, elev. 450 m / 1°00´S, 77°25´W // 2 January 1995 / E.S. Ross, collector / California Academy Sci.” (CASC) .

Remarks. The new species habitus is similar to Sphenorhina melanoptera, but differs by the non-acute posclypeus and the shape of the male and female genitalia. The populations examined are different in body size. Those from Napo Province are shorter in length than those from Santiago Province.

Etymology. The specific name - “ tiobino ” - is a noun in apposition in honor of Professor Albino Morimasa Sakakibara, who the first author (GSC), his graduate student, affectionately called "Tio Bino".
