Cephisus siccifolius [sic]: Stål, 1866 : 384 (incorrect synonymy).? Cephisus siccifolius cubanus Metcalf & Bruner, 1944 : 112 . Type locality. Unknown locality in Mexico . Diagnosis. The common species in Central America , variable in size and color, probably a species complex. Head 0.8x as wide as pronotum (lateral margins of pronotum thus longer than 3/4 length of eye); robust to rather slender, tegmina 11–15 mm long. Tawny to brown, darker on midline of crown; clypellus and lower fifth of frons blackish brown; usually with paler areas forming indefinite lineations on pronotum, and 3 crescent-shaped oblique bands across middle of each tegmen; sometimes entire dorsum tawny, contrasting with tegmina. Style with short, broadly rounded apical process and slender, strongly hooked dorsal process on inner edge ( Fig. 12 C); theca shaft slender, recurved, armed with a pair of short, recurved lateral processes and a pair of ventroapical processes 1.5x as long as lateral pair, extending nearly to base of shaft ( Fig. 12 B). Length: male 11.5–14.5 mm , female 13.5–18.5 mm . Width across head: male 3.3 mm , female 4.0 mm; across pronotum: male 4.2 mm , female 5.0 mm. Types .

Distribution. Mountains of Central America , from Panama to Mexico ; entering the southern USA in subtropical regions of Arizona and Texas. Remarks. This species is very variable in color ( Figs. 1 E–H), size, robustness and angularity of crown ( Figs. 2 D–F) and apparently represents a biological species complex. Three specimens (#CNCHB 1904–11 , from 5 km N Oaxaca, 20 June 1979 ; #CNCHB 1905–11 from 17 mi SE Teopisca, Chiapas, 3–4 June 1969 , and #CNCHB 1906–11 from Lake Catemaco, Veracruz, 1 May 1969 ) were barcoded and found to be separated by 3.5–6% divergence with the specimen from Oaxaca showing the greatest individual divergence. By contrast, other Cercopidae have a maximum 1.5% genetic divergence within a species. It will probably require biological studies to separate these species; and even then, the identity of the type of variolosus may remain in doubt. The female holotype of variolosus is 16.0 mm long, 5.1 mm across the humeral angles and has a right-angled crown (as in Fig. 2 F), which is as slender and even longer in the crown than in Metcalf's illustration of cubanus . A strikingly bicoloured form from Mexico , with the dorsum and upper half of frons ochre-yellow, contrasting with unmarked dark brown tegmina ( Figs. 1 F, 2D) and blackish venter, is represented by the single male from Cocoyac (AMNH) and the female from 20 mi N Iguala (CNCI). This may represent yet another unnamed species, but until more recent material suitable for barcoding, or an unmixed series is found, it is regarded as just another variant of a variable species. Another contrastingly marked form, with tawny dorsum and blackish tegminal bands, is known from 2 rather small females ( 13.6–14.5 mm ) from Ecuador : Rio Panlenque, 30 July–10 Aug. 1974 (J. Dryan) in FMC. The discovery of males may show that this is an additional species. The specimens taken in Cuba might be still another unrecognized species, but there is a distinct possibility that these represent an introduction of some mainland form.
