Head: Frons mostly brownish black to black, sparsely brownish microtomentose, more so on anterior portion, subshiny, ocellar triangle extended to anterior margin of frons, some specimens with grayish red areas along anterior margin just dorsad of antennal bases, parafrons with narrowly oval, densely microtomentose areas at anterolateral corner. Antenna mostly black, only basal flagellomere with ventrobasal area with some yellowish to yellowish orange coloration. Face narrow, mostly shiny black, especially over greater medial portion, extreme lateral margin adjacent to parafacial yellowish, narrow whitish gray, transverse band just ventrad of antennal base and through dorsal portion of antennal grooves, ventral half of face slightly receded; bearing2 larger facial setae, dorsal seta at about midfacial height, dorsomesoclinate; ventral seta just dorsad of epistomal margin, slightly dorsoclinate; parafacial thin, yellow dorsally, adjacent to eye, black ventrally and extended to gena. Gena short, gena-to-eye ratio 0.04-0.06. Thorax: Mesonotum uniformly sparsely microtomentose, brownish black to black, subshiny; presutural supra-alar seta well developed; pleural region black; dorsal 2/3 of anepisternum finely granulose, subshiny, anteroventral portion smooth, shiny. Wing hyaline, lacking any pattern or markings; costal vein ratio 0.80-0.81; M vein ratio 0.61-0.64. Legs, except tarsi, black; tarsi yellow; apical 1-2 tarsomeres darker, tan to brown; forefemur with sparse row of 4-5, stouter, spine-like setae along apical half of posteroventral surface. Abdomen: Generally black, subshiny to mostly shiny, dorsum of tergites very sparsely and finely microtomentose, faintly whitish gray; sternite 3 of male rectangular, parallel sided, length twice width; sternite 4 of male rectangular, length almost twice width; sternite 5 of male as 2 sternites, length nearly twice greatest width, anterior margin narrow, becoming slightly wider on anterior 1/3, thereafter tapered to a posterolateral point, lateral margin straight, medial margin angulate. Male terminalia (Figs 45-48): Epandrium in posterior view (Fig. 45) robustly oval, arched and thin dorsally, gradually becoming wider ventrally than narrowed on apical 1/3, in lateral view (Fig. 46) with dorsal 2/3 thirds narrow, strap-like, thereafter ventrally abruptly widened with anterior, pointed extension, ventral margin broadly rounded; cerci in posterior view (Fig. 45) elongate, narrowly semicircular, ventral apex more acutely pointed than more widely produced dorsal margin, in lateral view (Fig. 46) irregularly, narrowly semihemispherical, wider subdorsally than ventrally; gonite in lateral view narrowly rod-like, arched, only slightly wider toward aedeagal base than toward hypandrium, in ventral view (Fig. 47) robustly hook-like with shank of hook narrow and rounded portion very robustly developed; phallapodeme in lateral view (Fig. 48) L-shaped, arm extended to aedeagal base slightly more robust, length of botharms about equal, in ventral view (Fig. 47) as a dog bone, expanded at each apex; hypandrium in lateral view (Fig. 48) elongate, robust, sinuous, more or less parallel sided, in ventral view (Fig. 47) as a very robust H with long posterior arms, lateral marginsconspicuously sinuous, anterior emargination shallowly concave, posterior emargination deep, broadly U-shaped.  Figures 43-44. Lamproclasiopa ecuadoriensissp. n.

Baptista, M. Kotrba/ USNM ENT 00118307 [plastic bar code label]/HOLOTYPE ♂ Lamproclasiopa ecuadoriensisCosta, Mathis & Marinoni USNM [red]." The holotype is double mounted (minuten pin in a plastic block), is in excellent condition, and is deposited in the USNM. Four paratypes (3♂, 1♀; DZUP, USNM) bear the same label data as the holotype.  Type locality. Ecuador. Orellana: RioTiputini Biodiversity Station ( 0°38.2'S, 76°8.9'W).  Distribution (Fig. 104). Neotropical: Ecuador (Orellana).  Etymology. The species epithet, ecuadoriensis, refers to the country of Ecuador, where this species was collected.  Remarks. This species is similar to Lamproclasiopa laeviorand Lamproclasiopa polita, although it can be distinguished from congeners by the densely microtomentose anterolateral, narrowly oval black velvet spots on the frons; the narrow, shiny black face; the comparatively elongate costal section III (section III slightly less than section II); and the shape of structures of the male terminalia (Figs 45-48).
