FIGURE 2. Comparison of head shields and head pores of sympatric Anthalona acuta n. sp. from type locality (F–I) and Anthalona verrucosa verrucosa (Sars, 1901) (A–E). Parthenogenetic females of A. verrucosa verrucosa were raised from dried mud from temporary dune pool at the Lençóis Maranhenses, Brazil. A, F. Complete head shields. B–E., G–I. Variation in head pore morphology. Note the differences in distances between large and small pores, especially in A. verrucosa (B–E).
