Cerci of male with tricholiths, ventral view.—Species: A: Euthyrrhapha pacifica, Cap Verden, Cv 35/7; B: Tiviella inconspicua, Bo 612; C: Homoeogamia mexicana, Bo 1180; D: Polyphagina algerica, Bo 1376; E: Arenivaga bolliana, Bo 1407; F: Eremoblatta subdiaphana, Bo 1415; G: Ergaula cf. capensis, Bo 1185; H: Therea cf. petiveriana Bo 1378; I: Polyphaga aegyptiaca, from Lesbos, ex. cult.; J: Anisogamia tamerlana, Bo 1401; K: Psammoblatta livida, Bo 1334.—Number of tricholiths per anulus: A: one or two (at the base few anuli); B–F: two; G,H: three; I–K: more than five.—Enlargements: Scale in B 0.1 mm, in all others 0.25 mm.

FIGURE 19. A–C. Cerci of male with tricholiths, ventral view, all species with more than five sensilla per anulus.—Species: A: Eupolyphaga spec. 2, Bo 1367; B: Heterogamisca bolivari, Syntype, Bo 1356; C: Mononychoblatta semenovi, Bo 1391; D: Heterogamisca cerverae, Bo 1404.—E–H.
