In the bachue species group, which contains most of the species, the first antennal flagellomere is distinctly longer than the second flagellomere, the clypeus is maculated with yellow or cream, the fifth sternum bears stout spines midapically, and the seventh tergum is medially emarginate on its distal margin.
They provide an excellent opportunity to study how 2 potentially complementary sensory systems, vision and olfaction, have evolved at day/night transitions, because species in the group have distinct activity times, diverse eye and antennal morphologies and advanced sensory gene networks.
Antennal segments III, VII and VIII, base of IV and V, and all tibiae and tarsi pale brown.
Larva with robust, wide spatula with 3 to several points, and 8 short terminal papillae; antennal horns of pupa strong, broad, and serrate; female cerci of most species fused; gonostylus attenuate in male, R5 about 3/4 of the length of wing (Mohn 1964; Gagne et al.

Male-male agonistic behavior, for example, is primarily related to territoriality, and dominance is established through antennal contact, stridulation, and fights (Alexander 1961, Khazraie and Campan 1997, Prado 2006, Wilson et al.

Antennae inserted laterally near middle of rostrum, relatively short, reaching anterior margin of pronotum; scape large, elongate, weakly clavate, about 5.5 times longer than wide, 0.6 times as long as rostrum; flagellum short, compact, 4-articled (appears 3-articled), flagellomeres indistinctly visible, subequal in length, trapezoidal, widened distally, last flagellomeres wider than previous; antennal club 1-articled, ovoid with widely rounded apex, dilated apically, nearly as long as flagellum, apically subtruncate.
We measured several morphological traits of all the individuals (see Figure 1; head width (HW), head length (HL), thorax length (TL), pronotum length (PN), length of right forefemur (FF), foretibia (FT), midfemur (MF), midtibia (MT), hindfemur (HF), hindtibia (HT), width of posterior end of 1st segment of abdomen (AW), and lengths of the left antennal scape (AS) and the antennal funiculus (AF)) to 0.001mm using a freeware (ImageJ, ver.
