Oedothorax lacteovittatus Mello-Leitão, 1944: 327  , fig. 9 (Male and female lectotypes from La Plata, Buenos Aires, Argentina, R. Costa leg., deposited in MNRJ 1963View Materials, examined). 

Glenognatha lacteovittata: Ramírez, 1996: 35  , figs. 1–10; Cabra-García et al. 2014: 1029, figs. 1M, 3C, 8D, 9K –L; World Spider Catalog 2015.

Diagnosis. Males of G. lacteovittata  resemble those of G. boraceia  and G. florezi  by the short distal portion of the paracymbium ( Figs. 22HView FIGURE 22, 23HView FIGURE 23) and the embolic medial groove limited to the inner surface of the embolus ( Fig. 23OView FIGURE 23). It can be distinguished from the two latter species by the presence of filiform projections in the embolus distal region ( Figs. 23G, NView FIGURE 23). Females are diagnosed by the presence of two posterior cheliceral bulges ( Fig. 20EView FIGURE 20, 21E –FView FIGURE 21).
