Figs. 28, 31, 40  
 This is the most distinctive of the 3 new species of the M. velasquezi group from Brazil and unlikely to be confused because of its elongate, spine-like endophallic spines.   
Adult. Length of forewing: male 2.5–2.9, female 2.6–3.3 mm. Forewing with forks I, II, and III present, hind wing with fork II only. Spur formula 0:3:4. Overall color dark brown. Legs brown, tibial spurs somewhat darker in color, but not strongly contrasting with legs, apices of tarsi whitish. Wing bar at anastamosis marked with white, contrasting setae.  
Male genitalia. Ventral process of segment VI posteriorly projecting, elongate, narrow, length more than 2 times width at base (Fig. 28E). Segment IX moderately rounded anterolaterally, length greatest in ventral 1/2, posterolateral margin nearly linear; segment deeply excised dorsomesally and ventromesally, forming lateral lobes, lobes separated dorsomesally by about 1/2 width of segment. Tergum X moderate in length, simple in structure, with deep, broad, U-shaped mesal excision; apical lobes, as viewed laterally, distinctly projecting, rounded to subacute apically. Inferior appendages almost completely fused to phallic ensemble, basally with short, setose, anteriorly-directed lobes, apically with elongate narrow lobes. Mesal pockets of fused inferior appendages very bulbously enlarged, with elongate, spine-like, posteriorly-directed apicoventral projections. Paramere appendages very narrow, elongate, slightly dorsally curved, about as long as dorsal phallic spine. Phallotheca very short; ventral rod-like appendages elongate, with widely flared apices. Dorsal phallic spine, as viewed dorsally, broad in middle, gradually narrowed and rounded apically; as viewed laterally, relatively narrow, sharply upturned at about apical 1/3rd. Phallicata with lightly sclerotized, slightly scabrous, rounded lateral lobes. Endophallic membrane relatively simple in structure, dorsally with small, rounded sclerite, apparently articulating with ventral margin of dorsal phallic spine; laterally, on either side, with very prominent, sclerotized, anteriorly-directed spine-like processes.

Etymology. We take great pleasure in naming this species for Dr. Claudio Froehlich, both in recognition of his long career of working with aquatic insects in Brazil and also for his personal assistance during our collecting efforts in the country.
