Explanation of Names
Brachinus (Neobrachinus) elongatulus Chaudoir, 1876
Identification
It differs from very similar B. texanus, B. elongatulus in that it has notably a
limited southwestern range;
elytra distinctly broader (but equally elongated) and with
more prominent costae (glabrous longitudinal ridges);
color of elytra with bluish reflection (may not be visible at all angles, not grey-greenish);
tarsi more likely to be darker.
The styli of the female ovipositor are rounded apically ending in obtuse points, not acutely narrowing as in female B. texanus.
