Recognition

A provisional key to the genera of Cenchreini is here.

Pale, robust; frons compressed but not extremely; lateral margins of pronotum weakly modified, pustules along claval vein; clavus closed, media and cubitus each with 2 branches; pygofer with medioventral process.

Subgenus Persis: Vertex markedly produced before eyes, acutely angulate in profile (vs. Eritalaena Fennah 1952); antennal fovea absent

Subgenus Eritalaena Vertex not produced, forming with frons an obtuse angle in profile (vs. s.g. Persis)
Head without a subantennal process ; tegmina fully three times as long as broad; a distinct Sc+ R + M stalk ; Sc + R fork at least distad of basal third, M3 and M4 united in a common stalk as far as subapical cross-veins (vs. Goneokara Muir)

Subgenus Anapersis (vs Eritalaena  and Persis): Lateral pronotal carinae and ventral margins of pronotum foliate, forming an antennal fovea; (vs. Neocenchrea); Tegmina with papillate portion of anterior margin distinctly shorter than smooth basal portion (node distad of middle); pygofer with a medioventral process

Persis arizonensis (Patagonia, Santa Cruz County, Arizona 31.540307, -110.731207 Sept 17, 2018)

Persis (Persis) stali and Persis (Persis) novacula from Fennah 1952

Description of subgenus Persis from Fennah 1952

Head compressed, in profile more or less acutely angulate at apex; vertex elongate, narrow, tapering distally; lateral margins elevated ; frons elongate, narrow, with lateral carinae subparallel and raised; eyes excavate posteroventrally ; antennae short,  subglobose.  Pronotum very short, laterally wider, with a low curved ridge behind eyes and  lateral margin shallow but definitely laminate, bounding an extremely shallow antennal fovea. Tegmina long, narrow, almost parallel-sided; Sc+R fork slightly basad of  middle, M forked about level with apex of clavus, Cu1 forked about level with Sc+R fork, R and both branches of M forked near apex.

Persis (Anapersis) spreta from Fennah, 1952

Persis (Anapersis) gegaria from Fennah 1952

Description of subgenus Anapersis from Fennah (1952), with comments

Head with eyes narrower than pronotum; vertex about l.5 times as long as broad, with straight sides narrowing anteriorly; width at apex about half width at base; anterior margin carinate, transverse; posterior margin subrectanugulately excavate, disc  moderately  depressed; lateral margins in profile horizontal, meetmg those of frons subangulately; frons moderately narrow, medially ecarinate; lateral margins raised, not quite parallel, gradually widening from base to apex; subantennal process absent; antennae with first  joint short, ringlike, second short, obovate; clypeus about as long as frons, tricarinate, rostrum just attaining post-trochanters. Pronotum widely angulately excavate posteriorly; median carina prominent, elevated; sublateral areas strongly inclined away from it to lateral margins; lateral marginal carinae forming a fovea, with the dorsal margin foliate, not merely carinate; mesonotum slightly broader than long, feebly tricarinate. Tegmina long, costal and commissural margins parallel, apical margin anteriorly rounded, then straight and obliquely truncate. Sc + R + M fork at basal fifth, Sc+R
forking basad of, and M forked about level with, apex of clavus, Cu1 forked about level with union of claval veins, Sc and R together with three branches at apical margin, M with 4, Cu1 with 2.  Wings ample, only a little shorter than commissural margin of tegmina; R simple to
apex, M simple, Cu1 with two branches.  Anal segment of male relatively long and narrow with anal style near apex. Pygofer with a well-developed medio-ventral process.
Anal segment of female short, broader than long. Pregenital sternite broadly produced and rather deeply rounded on posterior margin, in profile shallowly sinuate.

This subgenus is distinguished from typical Persis by the prominent pronotal foveae, which are obsolete in Persis, and by the narrow form of the medioventral process of the pygofer. The profile of the head is considerably different. The subgenus differs from Neocenchrea, to which its type species was originally referred, in shape of head, in the presence of a carina between vertex and frons, in the more strongly developed dorsal margin of the pronotal foveae, in the relatively broader mesonotum, in the shape of the tegmina, in the presence of a medioventral process on the pygofer and in the pattern of the aedeagus and genital styles.

Description of Persis (Eritalaena) from Fennah, 1952
Vertex with lateral margins in profile horizontal, little produced beyond level of eyes, rounding into base of frons; frons moderately narrow, medially ecarinate, lateral margins elevated, subparallel; no subantennal process on genae; antennae with first segment short; ring-like, second short subovoid; clypeus about as long as frons. Pronotum with marginal carinae obsolete, no antennal fovea developed.  Tegmina long, costal and commissural margins parallel, apical margin rounded Sc+R+M fork at basal fifth, Sc+R forking basad of, and M forked about level with, apex of clavus; Cu, forked almost level with union of claval veins, Sc and R together with 3 branches at margin, M with 4 and Cu1 with 2.  Anal segment of male relatively long and narrow with anal style near apex. Pygofer
with a short triangular medioventral process. Anal segment of female short, broader than long. Pregenital sternite produced on hind margin in a large deeply rounded lobe which is longer than basal part of sternite.

This subgenus is distinguished from the typical subgenus and from Anapersis by the shape of the head in profile, by the absence of distinct lateral carinae on the pronotum, by the shape of the medioventral process of the pygofer and of the posterior lobe of the pregenital sternite.
