FIGURE 3 in Review of the genus Chagasia (Diptera: Culicidae: Anophelinae)

FIGURE 3. Scutum (dorsal view) of (A) Chagasia bonneae and (B) Ch. fajardi. The acrostichal scales (red arrows) are entirely pale in Ch. bonneae and dark posteriorly in Ch. fajardi (some scales have been lost in specimen shown); pale para-supraalar scales (yellow arrows), absent in the former species, are often present in the latter species. Note that the dorsocentral scales on the anterior promontory are distinctly yellow in Ch. bonneae but more or less unicolorous with the other dorsocentral scales in Ch. fajardi.
