Touroultia swifti Nearns and Tavakilian , sp. nov.

( Figures 4b, d )

Description. Male. Length 14.0 mm (measured from vertex to elytral apices), width 5.8 mm (measured across humeri). Habitus as in Fig. 4b . General form elongate-ovate, moderate-sized. Integument dark brown or black, with pale testaceous and dark brown variegated pubescence; pedicel, base of scape and antennomere III with grayish pubescence; base of antennomeres IV-XI with golden-yellow pubescence; elytra with predominantly dark brown pubescence, with two feebly defined regions of pale testaceous pubescence near middle.

Head with frons elongate, about width of 1 lower eye lobe (as in Fig. 4d ). Eyes with lower lobes distinctly large, oblong; narrowest area connecting upper and lower eye lobes about 4 ommatidia wide. Genae transverse, about 1/3 as tall as lower eye lobes.

Antennae about 1.5 times longer than body; antennal tubercles prominent, moderately separated; tubercles armed at apex with short blunt tooth; scape robust, clavate; antennomere III sinuate. Antennal formula based on antennomere III: scape=0.67; II=0.16; III=1; IV=0.85; V=0.82; VI=0.7; VII=0.55; VIII=0.56; IX=0.63; X=0.65; XI=0.71.

Pronotum subcylindrical, transverse, about 1.25 times as wide as long, sides feebly sinuate; disk with three moderately elevated tubercles, median tubercle oval, lateral tubercles more prominent; one basal transverse sulcus, and a more distinct oblique sulcus laterally which continues down the side.

Scutellum transverse, apex rounded.

Elytra about 1.6 times as long as width at humeri ( Fig. 4b ), about 3.75 times as long as pronotal length, about 1.6 times broader basally than pronotum at widest (at base); lateral margins slightly sinuate, gradually rounded to apices at apical 1/3, apices individually rounded; base of each elytron with a moderately-elevated gibbosity; basal 1/3 of elytra with dense punctation, surface finely granulatepunctate; humeri prominent, anterior margin oblique, angle with moderate sized, obtuse tubercle.

Venter with procoxae large, globose, with small, acute tubercle; narrowest area of prosternal process between procoxae distinctly narrow, about 1/10 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about 0.75 times as wide as mesocoxal cavity; mesosternal process feebly emarginate. Fifth sternite slightly longer than IV, apex feebly emarginate.

Legs moderate in length; profemora robust; meso- and metafemora feebly clavate apically; tibiae slightly expanded apically; metafemora about 1/3 as long as elytra.

Female. Length 17.0 mm (measured from vertex to elytral apices), width 7.5 mm (measured across humeri). Similar to male except antennae about 1.25 times as long as body; procoxae without tubercle; fifth sternite about 1.5 times as long as IV, with a median triangular impression.

Type Material. Holotype, male ( Fig. 4b ), “ Ecuador, Napo Prov., 24km E. Atahualpa, 450m, Sept 20- 22, 1996, E. Giesbert, coll.” ( EFGC) . Allotype, female, “ Ecuador, Napo Pr., 1 km W Coca , 08 Oct 1997, F. T. Hovore, coll.” ( ENPC) .

Etymology. We are pleased to name this species for Ian Patrick Swift, with appreciation of his friendship, encouragement, and camaraderie in the field. The epithet is a noun in the genitive case.

Diagnosis and Remarks. This species is distinguished from its congeners by the combination of the following characters: genae transverse, about 1/3 as tall as lower eye lobes; base of antennomeres IV-XI with golden-yellow pubescence; base of elytra with surface finely, shallowly, granulate-punctate; elytra with basal gibbosities moderately elevated. Touroultia swifti , sp. nov. is described from two specimens: one male and one female. Nothing is known about the habitat and behavior of this species; however, both specimens were collected in Ecuador and the male specimen was collected at 450 m elevation .
