Princis (1967) listed 2 species of Pinaconota , viz. bifasciata (Saus- 
sure) and obliqua (Walker). Ischnoptera (?) sicca Walker was 
synonymized by Kirby (1904) with bifasciata, but I (1973a) showed 
that Kirby was incorrect in his interpretation of the species and 
placed sicca in the new genus Alphelixia. The male genitalia and 
other morphological characters of obliqua indicate that this species 
is not a Pinaconota and a new genus is erected for it (see below). 
In describing Pinaconota, Saussure (1895) simply stated that the 
hind metatarsi were very short, with a fringe of long hairs, and a 
large apical pulvillus. Shelford’s (1910) characterization of the 
genus is as follows: Form depressed. Pronotum trapezoidal, an- 
teriorly and posteriorly sub-truncate, deeply punctate. Scutellum 
exposed. Tegmina and wings fully developed, extending beyond 
the apex of the abdomen. Femora moderately spined beneath. Tarsi 
very short, fimbriate, and entirely unarmed beneath ; posterior meta- 
tarsus equal in length to the two succeeding joints, its pulvillus large. 
Arolia very large. In this generic description, Shelford was appar- 
ently influenced by his belief that Ischnoptera ( ?) obliqua Walker 
was a Pinaconota. 
Pinaconota can be recharacterized as follows: 
Pinaconota Saussure 
Type-species: Blatta bifasciata Sauss., Monotypy (1895, p. 337) 
Both sexes with tegmina and wings abbreviated, or extending 
slightly beyond the end of the abdomen. Ventro-anterior margin of 
front femur with 2 or more, small, heavy spines, followed by a row 
of small uniformly spaced slender setae, terminating in a large distal 
spine; ventro-anterior margins of mid and hind femora with 2 or 3 
widely spaced spines, with or without distal spines; hind metatarsus 
short with 2 rows of fine ventral setae; pulvilli and arolia very
