Diagnosis.

Head broad, with lateral vertexal foveae deep, non-setose, closer to eyes on each side than to each other; antennal bases slightly swollen but not set off by striae; antennae rather short, antennomere III slightly longer than wide, IV – VII short and beadlike, VIII slightly transverse, IX – XI forming a loose club, IX transverse, X (in male) with flattened densely setose upper surface, terminal antennomere bluntly acuminate, with small setose depression on anterior surface; pronotum subangulate laterally, widest just basad of middle, lateral and median basal foveae present; male pronotal disk (Fig. 7 G View Figure 7 ) with simple small, round depression in anterior 1 / 2, glabrous within, with just a few posteriorly directed setae along anterior margin; each elytron with three dorsobasal foveae, one at base of sutural stria, other as a closely set pair near humerus; most male ventrites (Fig. 5 G View Figure 5 ) flattened at middle, first visible sternite with dense patch of setae along posterior margin, slightly clustered to sides, posterior marginal fringes of setae on 2 nd and 3 rd visible ventrites thinner but also evident; last visible ventrite short, shallowly depressed, with small median cluster of convergent setae; last abdominal tergite strongly curved ventrad, surface matte, slightly emarginate apically. Aedeagus (Fig. 8 H View Figure 8 ) broad and somewhat inflated at base, with strongly sclerotized ventrobasal bridge, the bridge with rounded, separate setose lateral lobes and triangular posterolateral lobes, connected by membrane to separate, irregular setose sclerites; median lobe broadly emarginate apically, dorsally on each side with elevated setal base, and very thick apically directed seta; venter of median lobe with long, laterally and apically fimbriate median plate; apical ventral margin with bilateral lobes bearing tufts of long setae as well as expanded, membraneous microdentate flaps. TL 1.48 mm, EW 0.38 mm.

Distribution.

This species is known only from the El Pahuma Orchid Reserve, northwest of Quito in Pichincha province, Ecuador.

Etymology.

The name of this species mean ‘ lost’ or ‘ outcast’ due to the fact that it seems to be a phylogenetic outlier (and maybe interloper) in this genus.
