Chrysomela serpentina Rogers was one of the earliest species of Calligrapha to be described and it was well known to entomologists in the late XIXth Century, who considered the range of the species to reach from the southern United States to Venezuela (e.g., Stål 1865; Jacoby 1882; Weise 1916). It took several decades until Julien Achard (1923b) noticed that the specimens previously classified as C. serpentina from Venezuela in fact belonged to a different species, which was described under Polyspila sallei. The confusion between the two species for such a long time was understandable considering that C. sallei (Achard) really looks like a small version of C. serpentina (Rogers), with a remarkably similar pattern of dark markings on the elytra, so characteristic of this species. The description of this species does not indicate whether it was based on a single type or a syntype series; it simply mentions Sallé as the source of the specimen(s). For simplicity, I will consider that he used a single specimen, the holotype labeled by the author that is preserved in the National Museum in Prague (Czech Republic), and will be redescribed below.

Hypomera triangular, convex on disc and transversally depressed basally, alutaceous and unpunctured; hypomeral suture impressed, but not neatly defined, nearly obsolete at both ends, gradually diverging from pronotal margin from posterior angle towards base of anterior angle. Prosternum relatively long in front of procoxae, surface microreticulate, nearly unpunctured on anterior half with large, oblique punctures posteriorly near procoxae; anterior border regularly concave, finely margined; process narrow, slender, widened posteriorly, rather convex in transverse section, feebly carinated longitudinally at middle, sparsely punctured, with few semierect yellow setae. Scutellum large, 1.4x longer than wide at base, with sides weakly curved toward broadly round apex; surface very finely microsculptured, unpunctured. Mesepimera and mesanepisterna finely microreticulate; mesanepisterna with scattered shallow round punctures, restricted to anterior angles in mesepimera. Metanepisterna finely, superficially microreticulate, moderately densely impressed with longitudinally elongate punctures, becoming rugose in posterior third; punctures on frontal half anteriorly with short, very small whitish seta directed posteriorly. Metaventrite longer than combined prosternum and mesoventrite, with broad, short subtrapezoidal anterior process and round anterior angles; posterior border between metacoxae broadly concave; surface nearly smooth on disc, with fine transverse impressions and delicately longitudinally impressed discrimen in posterior half, finely microreticulate at sides with sparse and fine small punctures and larger shallow punctures near anterior angles. Elytra long, 0.8x as long as body, rather regularly convex, wider at base than base of pronotum, with humeral angles broadly round, sides very weakly curved, widest at middle, and regularly curved in apical third; surface very finely microsculptured, with small punctures, larger and deeper around and within dark markings, with scutellar row of nine slightly confused punctures, and regular premarginal row of tight small punctures from sutural angle to humerus, slightly irregular through dark markings; elytra with slightly explanate dark margin from humeral area to sutural angle, invisible from above due to lateral convexity of elytra. Dark markings of elytra (Fig. 7e) consisting of: (i) sutural stripe narrow, parallel to suture, reaching base of elytra narrowly surrounding scutellum, gradually thining at apical declivity to reach sutural angle; (ii) subsutural stripe narrow, with basal end at level with apex of scutellum, divergent from sutural stripe basally for six punctures, and entirely confluent beyond, gradually narrowing posteriorly, but slightly enlarged at apical declivity of elytra before abruptly disappearing preapically, completely delimited by punctures, with few interstitial isolated punctures in apical area; (iii) arcuate band entire, weakly concave externally, parallel to and completely separated from subsutural stripe by pale interval as wide as arcuate band; apical fifth prolonged laterally as slightly oblique anteriorly concave and posteriorly irregular transverse stripe, ending at lateral declivity of elytra close to premarginal row of punctures, at same distance as space from this row to margin of elytron; (iv) internal humeral depression at basal margin of elytron with small dark spot; (v) humeral marking separated from base of elytra and consisting of completely fused narrow elongate humeral spot and humeral lunule forming long humeral stripe curved toward suture, weakly sigmoidal in apical quarter and completely fused laterally with basal fifth of arcuate band; punctures associated to humeral marking distant from perimeter, and marking with relatively numerous interstitial punctures; (vi) spot enclosed by humeral lunule medium-sized, longer than wide and reniform, free and equally distant from humeral lunule and subsutural stripe; (vii) subhumeral spot small, elongate and irregular, free, covering about four punctures of premarginal row of punctures; (viii) midlateral spot small, broadly elliptical, about twice as long as wide, covering some six punctures of premarginal row, externally fused completely with dark margin of elytron; (ix) spot of apical declivity and apical spot subequal, elongate, about twice as long as wide, convergent posteriorly directed to sutural angle at apical declivity of elytron, equidistant between subsutural stripe and spot of apical declivity, between spots, and apical spot and elytral margin, with external margin of apical spot reaching premarginal row of punctures; (x) four additional spots on disc, one medium-sized, roundish, at lateral declivity of elytra and posterior to humerus, at level with midpoint between subhumeral and midlateral spots, equidistant from lateral border of elytron and posterior end of humeral marking, with punctures near periphery and within spot; one large, roundish spot in apical third of lateral declivity of elytron, placed at concavity of posterior transverse prolongation of arcuate band; one medium sized elongate transverse and slightly oblique spot on disc, slightly behind level of midlateral spot; and one irregularly ovoid spot, smaller than midlateral spot, at lateral declivity of elytron, aligned with posthumeral additional spot and outer end of transverse stripe, placed slightly behind midlateral spot.

I have not seen many representatives of this species and they tend to be rather constant in their appearance, apart from occasional confluence of elytral markings, specially the additional spots, with surrounding features. Distribution. This species, closely allied to C. serpentina and relatives, is the only species in this group occurring in South America, and based on the limited information we have available, it is allopatric with every other species of Calligrapha. In particular, it occurs in coastal areas of the Colombian and Venezuelan Caribbean, in two xeric biomes: the Guajira-Barranquilla Xeric Scrub and La Costa Xeric Shrublands (Fig. 11, black circles).Published as part of Gómez-Zurita, Jesús, 2021, Systematic revision of Calligrapha s. str.
