Abdomen: Tergites 3-4 with deep, gray to silvery gray wedges at lateral margins; tergite 5 of male mostly to entirely gray, sometimes with posterior margin darkened. Male terminalia (Figs 101-104): Combined structures generally moderately elongate, in posterior view height about twice width; epandrium with dorsal arch narrowly connected above cerci; dorsal half more or less generally sparsely setulose, ventral half with sparse, very short setulae; in posterior view (Fig. 101) as an inverted, angulate, moderately narrow U, ventral epandrial extension narrowed to just before greatly expanded, apical third, apical portion broad as an arrow point with broad, medial incision apically, in lateral view (Fig. 102) narrowly elongate, parallel-sided except for extended base of arrow point; aedeagus in lateral view (Fig. 104) elongate, about 5

The species epithet, miguelito, is to recognize Michael W. Mathis who is also known as &quot;Don Miguel&quot; or 
<normalizedToken originalValue="“Miguelito.”">&quot;Miguelito.&quot;</normalizedToken>
Michael guided us while conducting field work in Honduras where this species was collected. We are treating miguelito as a noun in apposition.

<paragraph pageId="59" pageNumber="60">Remarks.</paragraph>
<paragraph pageId="59" pageNumber="60">Structures of the male terminalia readily distinguish this species from congeners, especially those of the incisum group. Certainly unique to this species is the greatly expanded apical portion of the ventral, epandrial process, which is like a broad arrowhead. The expanded, ventral, epandrial process can be seen in ventral and somewhat in lateral views. The rectangular hypandrium that has a moderately deep and wide posterior emargination is also characteristic.</paragraph>
