Name, Location and Description

A description by Wm. T. Davis.

The description comes from Wm. T. Davis’ document A NEW VARIETY OF CICADA RESEMBLING C. DORSATA. from September, 2015, published in the Journal of the New York Entomological Society. Vol. 23: 161-164.

Markings resembling those of C. dorsata [now M. dorsatus], but marginata var. dealbata is more green in color and has less black about the central area of the pronotum. The mesonotum is marked as in dorsata but is more pruinose ; the turgum has a dorsal line of white spots as in dorsata, but the sides are broadly pruinose and the posterior margin of each segment is narrowly edged with greenish yellow. Beneath both insects may be of the same color, though dorsata is usually much darker. The opercula are about as broad as long and broadly rounded at the tips. The fore wings in dorsata are oval in shape with the inner side (radius) of the costal margin blackish ; the veins are heavy and thickened, and the W-mark is prominent, whereas in luarginata var. dealbata the fore wings are more acuminate in form, the costal margin is green, darkened beyond the middle of the wing and the W-mark is not conspicuous or is wanting. One of the greatest differences between the two insects is in the genitalia. The uncus in dorsata viewed at full face is narrow and the piece below into which it locks is broadly notched with the extremities rounded. In var. dealbata the uncus is more nearly triangular in shape and the lower piece is narrowly notched with the extremities much produced. The male type of var. dealbata is figured.

Length of body 35 mm. ; length of fore wing 46 mm. ; expanse of wings 105 mm.

William T Davis’s description from A New Cicada from Arizona:

Resembles Cicada marginata Say [now called Megatibicen pronotalis walkeri Metcalf, 1955] in size, color, and markings. Head black with an oblong greenish yellow spot each side between the eyes and a small spot of the same color on the front just above the transverse rugae. Pronotum greenish yellow with a large, conspicuous black spot occupying the fore part of its central area. The hind margin of the pronotum (collar) is entirely unicolorous as in marginata. The mesonotum is black, with a pruinose band each side at the base of the wings; the elevated x is greenish yellow, and there are two conspicuous, irregularly formed (pipe-shaped) greenish yellow spots occupying its central portion. The tergum is black, each side broadly margined with pruinose, and the segments have their posterior margins yellowish. There is also an indication of a dorsal line of pruinose spots on the tergum, which in the type have been nearly worn off. Beneath the head is blackish, the remainder of the insect being greenish yellow and more or less pruinose. The costal margin of the fore wing is entirely greenish yellow, darkened beyond the middle, and the w-mark is inconspicuous. Both fore and hind wings are greenish-yellow at base, with the veins darkened beyond the middle.

Neotibicen canicularis – the Dog Day Cicada

Neotibicen canicularis is one of the smaller Neotibicen. It’s better known as a Dog Day Cicada.

These photos come from a cicada hunt for auletes, but I found this canicularis as well.
