Megalostrata bruneri ( Bryant, 1936) View in CoL

Figs 14 View FIGURE 14

Chemmis bruneri Bryant, 1936: 331 , pl. 23, fig. 9 (♀ holotype from Loma del Gato , Sierra del Cobre, Cuba, MCZ 20592 About MCZ , examined by photographs).

Megalostrata bruneri View in CoL ; Bonaldo 2000: 118 (by genus synonymy).

Diagnosis. Females of M. bruneri are similar to those of M. paludosa spec. nov. and M. monistica by the short, bulbous secondary spermathecae ( Figs 12A, B View FIGURE 12 , 22C, E View FIGURE 22 ). They differ from those of M. monistica by the straight posterior margin of the epigynal plate, without a median invagination (posterior margin of epigynal plate strongly invaginated in M. monistica , Fig. 12A View FIGURE 12 ) and from those of M. paludosa spec. nov. by the small primary spermathecae (diameter similar to posterior atrium height), positioned anteriorly to the posterior atrium (primary spermathecae larger than the atrium height, positioned at the level of posterior atrium in M. paludosa spec. nov., Figs 22A View FIGURE 22 , 23C View FIGURE 23 ) ( Fig. 14C View FIGURE 14 ).

Description. See Bryant (1936).

Distribution. Only known from the type locality ( Fig. 25 View FIGURE 25 ).
