In the genus Blaptica the preputial spines are small and occur in 
multiple rows in obscura (Fig. 56) and dubia (Fig. 62) but are 
reduced in number and arranged in a single row in interior (Fig. 
59). According to Hepper (1965), Blaptica pereyrai Hepper is 
near B. dubia , but Hepper noted that the preputial spines of pereyrai 
are fewer in number than in dubia. The number of spines shown 
in Hepper’s (1965) figure 11 closely approximate those found in 
B. interior. The number of preputial spines in species of Blaberus 
is variable (Roth, 1969) and this is probably also true for the 
genus Blaptica. 
Rehn (1930, p. 62) stated that Styphon “. . . is a distinctive 
genus occupying an isolated position and not closely related to any 
of the other previously known genera.” The genus is found in the 
Dutch Leeward Islands and Rehn (1930, p. 67) further stated “It 
is most unexpected to find on these semiarid islands off the north 
coast of South America an entirely unrecognized genus which has 
no known close relative on the adjacent mainland. The genus jPara- 
hormetica , which is in some respects the nearest relative, is an 
inhabitant of regions widely removed in South America.” The L2d 
and prepuce of Styphon (Fig. 64) indicate a closer relationship to 
Blaptica (Fig. 59) than to Parahormetica (Figs. 199, 202, 203); 
the latter is a member of the Brachycolini (see below). 
Generic Group 2. Aspiduchus (Figs. 21-23), Byrsotria (Figs. 
24, 25), Eublaberus (Figs. 15-16), Hemiblabera (Figs. 17-20). 
In this group L2d is strongly hookshaped. The genera Aspiduchus 
(Figs. 97, 100, 103, 106), Byrsotria (Figs. 75, 78, 81), and Hemi- 
blabera (Figs. 84, 87, 90, 93, 96) all have very similar L2d’s and 
the preputial spines are somewhat elongated and arranged principally 
in a single row. Bonfils’ (1969, p. 132) drawing of the L2d and
