Mortoniella eduardoi (Rueda Martín and Gibon) : Blahnik and Holzenthal 2011: 53 [member of velasquezi group].

Mortoniella eduardoi is very closely related to M. licina , n. sp. and M. venezuelensis , n. sp. All of these species have the apical spine-like projections from the mesal pockets of the inferior appendages very elongate and fused to the ventral part of the inferior appendages to form elongate, projecting lobes. All of the species also have an endophallic membrane that is ornamented with a dorsomesal projection with minute spines, membranous lateral lobes with minute spines, and paired ventral sclerites, each with a somewhat forked apex. Among these species, M. eduardoi can be easily diagnosed by the modified apices of the paramere appendages, which are slightly widened preapically and have a spine-like apical projection. Additionally, the color is different, dark brown with a distinct white wing bar, rather than medium or light brown. Like M. venezuelensis , M. eduardoi has a distinct field of slightly darkened, upright, scale-like setae on the hind wing. The setae differ from those that parallel the major veins, both in this species and others in the subgenus Nanotrichia , which are leaflike and uniformly tapered on each end. The upright setae on the hind wings are narrow and stalklike basally, with the apices widened and flattened.

Adult —Length of forewing: male 2.6-3.0 mm; female 3.0- 3.5 mm. Forewing with forks I, II, and III present, hind wing with fork II only. Spur formula 0:3:4. Overall color dark brown, apices of tarsi paler. Tibial spurs slightly darker than legs, not or only weakly contrasting in color. Forewing with distinct white wing bar at anastomosis. Males with scale-like setae paralleling veins in forewing, hind wing with extensive field of slightly darkened, semi-erect, scale-like setae.

Male genitalia —Ventral process of segment VI posteriorly projecting, narrow basally, length about 3 times width at base. Segment IX with anterolateral margin rounded and distinctly produced in ventral ½, posterolateral margin nearly straight; segment deeply mesally excised dorsally and ventrally, forming lateral lobes, lobes separated dorsomesally by more than ½ width of segment. Tergum X, as viewed laterally, relatively short, narrowed and slightly ventrally curved apically; as viewed dorsally, short and wide, apicomesally with deep U-shaped emargination, extending more than ½ length of tergum; ventrolateral lobes slightly produced basally, obsolete apically. Inferior appendage with short digitate, setose, dorsolateral projections, fused apicoventrally to spine-like projections of the mesal pockets; composite apical structure forming prominent elongate, curved, ventral lobes. Mesal pockets of inferior appendage very large, with elongate, thick, spine-like apicoventral projections. Paramere appendage moderately elongate, narrow, extending nearly straight, slightly swollen preapically, with short spine-like apical projection. Phallobase very short, with elongate ventral rod-like projections, each strongly flared apically. Dorsal phallic spine, as viewed laterally, relatively narrow, strongly reflexed in about apical 1/3, apex rounded; as viewed dorsally, with distinct subparallel dorsolateral projections, narrowed basally and apically, reflexed apex rounded. Phallicata short, continuous with endophallic membrane apically, laterally with broadly rounded sclerotized projections, surrounding mesal pockets of inferior appendage. Endophallic membrane continuous with phallicata, dorsomesally with slightly raised projection with numerous minute spines, laterally with projecting membranous lobes with minute spines, apically with narrow projecting lobe, ventrally with pair of sclerotized projections, each with v-shaped apical notch (modified phallotremal spines?).
