Strumigenys moreauviae

Strumigenys moreauviae is known only from the holotype worker collected by a student, E. R. Millard, on a riparian island of the Rio Grande in late spring.

Identification
Of western species, S. moreauviae shares a similar dentition pattern with Strumigenys chiricahua and Strumigenys reliquia (tooth one and four of similar size and much shorter than similarly long teeth two, three, and five) but can be distinguished from these two species by head pilosity. Strumigenys moreauviae has no flagellate setae on head whereas S. chiricahua and S. reliquia have a pair at apicoscrobal position and a pair straddling the midline just anterior of the posterior margin of head. Strumigenys reliquia also has another pair about midlength of the upper scrobal margin and is the only western species with a fringe of simple fine and elongate setae on the anterior margin of clypeus. Otherwise, general head and clypeal pilosity is similar to western species Strumigenys arizonica, Strumigenys californica and Strumigenys mendezi, but dentition differs. The diastema is absent or shorter than the length of the first basal tooth in S. arizonica, S. californica and S. mendezi; in S. moreauviae it is longer.

The holotype is missing some body parts (the last funicular segment of the right antenna, the left foreleg beyond the trochanter, the right hind leg, and the left tarsal segments, and likely some pilosity). However, complementary body parts or setae are present to appear to represent a full description.
