Neotibilis (Neotibilis) ecuadorensis sp. nov.

( Figs. 3 and 4 )

Type locality: Ecuador, Napo Province, San Rafael

Type material. Holotype male, labeled: a) Equador, Napo, Sn Rafael , V/1986, L. Duque ( QCAZ)

Etymology. The species name refers to the type locality.

General shape ovate elongate. Dorsal surface dark castaneous. Jugae only slightly deflected dorsally. First antennal segment ochraceous, with dark punctures; remaining segments lacking in the specimen examined. Rostrum not reaching mesocoxae. Pronotum densely puncturedon dark castaneous; anterolateral margins reddish, bordered on light ocher. Scutellum: basal angles with 1+1 reddish ochraceous calli, smaller than those of other species of the subgenus; apex slightly deflected. Punctures on basal third of scutellum coarser than the remaining. Legs ochraceous, with reddish castaneous punctures on femora. Mestasternal carina flat. Abdominal venter light brown; abdominal tubercle stout, broader than those of N. (N.) claviformis sp. nov. and N. (N.) manauara sp. nov. Connexivum with asmall yellowish rounded spot occupying the median fifth of each segment, along outer lateral margin.

Male. Measurements (n = 1). Total length 14.69; head length 1.40; head width 2.41; eye width 0.66; interocular distance 1.09; anteocular length 0.50; length of antennal segments I – 0.93; II - V, lacking; pronotum length 2.84; pronotum width 7.04; scutellum length 6.01; scutellum width 4.4; abdominal width 7.04.

Pygophore ( Figs. 3, 4 ) subquadrangular, moderately open in dorsal view; dorsal rim sinuous, U-like along proctiger ( Fig. 3 ). Proctiger rounded apically. Parameres with fingerlike portion short, almost aslong as auriculate portion, which is concave dorsally. Posterolateral angles rounded. Ventral rim sinuous, more elevated on posterolateral angles and at apices of the narrow U-like mesial excavation ( Fig. 4 ). Laminar flaps of ventral rim complex, with two different portions: one, projected dorsad, and another sagitally disposed visible through excavation of ventral rim. Inner processes of ventral rim of pygophoretriangular, contiguous.

Female unknown.

Comments. Neotibilis (N.) ecuadorensis can be distinguished from the remaining species of the subgenus by the complex laminar flapsof the ventralrim of pygophore. The narrowly U-shaped excavation of ventral rim is also unique among the species of Neotibilis .
