( Figs 126–127 View FIGURES 123–131 )

Oxysarcodexia titubata ssp. fraterna Lopes, 1946c: 143   ; Mexico, Morelos, Cuernavaca. Holotype male and five male paratypes in MNRJ (not examined).

Diagnosis. Male. Length 9.5 mm. Postocular plate with golden pollinosity. Ocellar bristles small, but welldifferentiated. Thorax grayish. Three well-differentiated post-sutural dorsocentral bristles. Apical scutellar bristles present. Legs blackish. Abdomen grayish with golden pollinosity more intense on T5. T4 with 1 pair of median marginal bristles. ST5 with deep median cleft with margins almost parallel. Cercus, in lateral view, with the apical portion bent slightly backwards and pointed apex. Cercus with bristles present along the ventral surface (lateral view), except in distal third. Cerci with distal third narrower than middle part in posterior view; parallel. Pregonite with expanded base, gradually narrowing to apex; unicolorous. Postgonite smaller than pregonite; unicolorous. Distiphallus with a large ventral lobe and numerous pre-apical spines, smooth ventroapical margin, long and broad ventroapical projection with serrated margin, lateroapical expansions, small dorsoapical swelling, square/oblong apex and sinuous dorsal outline. Vesica symmetrical; distal lobes well developed, squared and sclerotized, with scale-like adornment on dorsal surface.

Remarks. Features used to differentiate O. fraterna   from the similar species O. peruviana   ( Fig. 226 View FIGURES 219–227 ) and O. vittata   ( Fig. 279 View FIGURES 274–283 ) are: cercus in posterior view parallel and with enlarged apex; ventral spines more developed than in O. vittata   ( Fig. 280 View FIGURES 274–283 ), and apex of distiphallus with a long and broad ventroapical projection with serrated margin and small dorsoapical swelling in O. fraterna   ( Fig. 126 View FIGURES 123–131 ) ( Lopes 1946c). See also remarks under O. ariozanoi   sp. n. and O. augusta   . Female unknown.

Distribution. NEARCTIC. Mexico (Morelos).

Biology. The species has been collected with traps used to collect fruit flies ( Lopes 1946c).
