description: Mortoniella intervales, new species   
Fig. 9  
 This is a distinctive species within the M. albolineata subgroup, easily diagnosed by the very elongate apicolateral projections of tergum X, ventrally recurved apex of the dorsal phallic spine, and presence of a ventromesal projection on the inferior appendages.   
Adult. Length of forewing: male 3.8–4.8 mm, female 4.3–5.0 mm. Forewing with forks I, II, and III present, hind wing with fork II only. Spur formula 0:4:4. Overall color dark brown. Legs same color, apices of tarsi whitish, tibial spurs somewhat darker than leg, but not strongly contrasting in color. Wing bar at anastamosis distinctly marked with white setae, band narrow, but more or less continuous.  
Male genitalia. Ventral process of segment VI laterally compressed, ventrally projecting, subtriangular, moderately elongate, wide basally, acute apically (Fig. 9D). Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin convexly rounded, narrowing ventrally; segment deeply excised dorsomesally and ventromesally, forming lateral lobes, lobes separated dorsomesally by much less than 1/2 width of segment. Tergum X with deep, V-shaped mesal excision and projecting apicolateral lobes, basolaterally with short rounded setose lobes; lateral lobes very elongate, tapering, acute apically. Inferior appendages with prominent and somewhat asymmetrically developed ventromesal projection; laterally, on each side, with setose, tapering, dorsally-directed lobes. Mesal pockets of fused inferior appendages with apical processes short, dorsally curved. Paramere appendages short, uniform in width, apices acute and somewhat upturned. Dorsal phallic spine, as viewed laterally, more or less uniform in width, gradually upturned in apical 1/2, apex acute and distinctly ventrally recurved. Phallicata rather distinctly sclerotized, with broadly rounded dorsolateral lobes and weakly projecting, rounded ventral lobes; apicodorsally with 2 pairs additional sclerotized lobes, the anterior ones elongate and fingerlike, the posterior ones short and rounded. Endophallic membrane relatively short and simple, with ventromesal spine; ventral spine short, stout, curved, apex acute; phallotremal spines absent.  
 Holotype male: BRAZIL: São Paulo: Parque Estadual Intervales, Rio do Carmo, 24°18'59"S, 048°25'15"W, 560 m, 29.ix.2002, Blahnik, Prather, Melo & Calor (UMSP000088142) (pinned) (MZUSP).   
 Paratypes: BRAZIL: São Paulo: same locality and date as holotype — 10 males, 9 females (pinned) (MZUSP, UMSP, NMNH).   
 Etymology. This species is named M. intervales, with the epithet used as a noun in apposition, for Parque Estadual Intervales, the very beautiful park where the type specimens were collected.
