2. Tegmina present as subtriangular lateral pads; male subgenital 
plate simple, without styli (Fig. 2) ; dorsum of male abdomen 
unspecialized. (Canary Islands, Azores } Europe, North Africa, 
western Asia; other Old World records subject to change with 
revised definition of genus) Loboptera Brunner 
Tegmina short, subquadrate, attingent or slightly overlapping; 
male subgenital plate complex, with styli (Fig. 6) ; tergum 7 of 
male abdomen with 2 small pores without associated setae (Fig. 
21). (Africa to Hawaii, other Pacific islands) 
Lobopterella Princis 
3. Dorsum of male abdomen specialized on tergum 7 (Figs. 15, 
20) ; posterior margin of female subgenital plate weakly cleft 
(Fig. 19). (Known only from Buenos Aires, Argentina) 
Agmoblatta , new genus 
Dorsum of male abdomen unspecialized; posterior margin of 
female subgenital plate entire. (Known only from San Sebastian 
Island about 60 miles east of Sao Paulo, Brazil) 
Isoldaia, new genus 
Princis (1957) stated that the male tergum is unspecialized in 
Lobopterella ; perhaps the pores on segment 7 were hidden under 
the 6th tergum in his museum specimens. 
Several genera of Old World Blattaria have been described to in- 
clude species appearing by traditional generic characters to be related 
to Loboptera. Specimens of most of these genera are not available to 
us at present to permit us to study the characters shown by McKit- 
trick (1964) to have special significance in higher classification. 
When such a study eventually becomes possible, the resulting realign- 
ment of genera may reveal which are most closely related to Agmo- 
blatta and Isoldaia and may suggest what the lines of evolutionary 
development have been. Brief characterizations of Loboptera and 
3 European species are included in Princis (1965). An illustration 
of the paraprocts of Loboptera decipiens similar to our Fig. 1, is in 
Bei-Bienko (1950, p. 169, fig. 67). The description of Lobopterella 
is in Princis ( 1957) . 
The present investigation tests the applicability of McKittrick’s 
higher categories and particularly her separation by genitalia and 
other characters of 2 groups of genera which for many years have 
been regarded as a single group, the Pseudomopinae. Our studies 
indicate that there is a basis for a fundamental distinction between
