Furthermore, in foveate
animals, high spatial resolution is mediated by cone vision.
When we foveate
a particular cell we tend to see that as having more horizontal mortar boundaries, while those outside the fovea are perceived as having larger tilts.
Most species of Diaparsis are conspicuously larger than Aneuclis and Sathropterus species, often have a deep and strongly oblique foveate
groove in the anterior part of the mesopleuron (this groove, if present, is usually weak in Aneuclis and Sathropterus) and they frequently have a densely and coarsely punctate head and mesosoma (impunctate or finely punctate in Aneuclis and Sathropterus).
Pronotal punctures on disc fine, sparse; punctures on outer rows of elytra large and foveate
; eastern Mexico D.
Prosternum with median portion including prosternal process narrow, slightly dilated anteriorly, lateral portions relatively wide, slightly depressed, prosternal hypomeron not foveate
for antennal club (Fig.
Saccadic latency, or reaction time, typically refers to the time from onset of the non-predictable step of target movement to onset of the saccadic eye movement initiated to foveate
the displaced target.
