Type locality.

ECUADOR: Pichincha: 7 km S Nanegalito [0°0.4'N, 78°40.6'W].

Type material.

Holotype male: "ECUADOR: Pichincha, Nanegalito, 7 km S on Nono Road, 1540m; 0°0'23"N,78°40'36"W 27-31 OCT 1999; Z. H. Falin, ECU1F99 070, ex: flight intercept trap" / "SM0353539 KUNHM-ENT" (SEMC). Paratypes (4): ECUADOR: Los Ríos: 1: CCRP [Centro Cientifico Rio Palenque], 21.xii.1980, S. Sandoval (CHSM); Pichincha: 1: Rio Palenque Sta., 47km S Santo Domingo, 250m, 5. v– 25.vii.1985, malaise/FIT, S. & J.

Falin (SEMC); 1: 16km E SantoDomingo, Tinalandia, 680m, 4. v– 25.vii.1985, malaise/FIT, S. & J. Peck (CMNC).

Diagnostic description.

This species is extremely similar to Operclipygus dubius   , differing mainly in the following characters: length: 1.50-1.62 mm, width: 1.15-1.22 mm; fragments of frontal stria more frequently evident; anterior submarginal pronotal stria barely recurved posterad, not reaching median pronotal gland openings which are about 8 puncture widths from anterior margin; prescutellar impression small, narrow, no longer than scutellum; lateral parts of pronotal disk with numerous very small punctures; prosternal striae more broadly separated, parallel in front; mesometaventral stria arched forward to middle of mesoventral disk, transverse in middle; propygidium sparsely covered with small deep punctures separated by about twice their diameters; pygidium with fine ground punctation very sparse, coarser punctures similarly spaced as on propygidium, sparser toward apex; pygidial marginal sulcus deep, crenulate (as in Operclipygus dubius   ). Male genitalia (Figs 31 H–K) as for group description, with the apices of S8 obliquely subtruncate, with about 4 long apical setae; T9 with apices obliquely subquadrate; T10 not divided; S9 truncate at base, with deep narrow apical emargination; tegmen more or less parallel-sided, rounded to apex.

Remarks.

The very short recurved arms of the anterior submarginal pronotal stria and male genitalia will distinguish this species from Operclipygus dubius   .

Etymology.

The name of this species refers to fact that all specimens are known from the Ecuadorian Andes.
