ETYMOLOGY

Derived from its host name Spondias ; Greek, geniljv spondiados.

HOST PLANT

Spondias purpurea L. ( Sapindales : Anacardiaceae ). Immatures are free living on leaves of the host.

COMMENTS

Adults of C. spondiadis diFer from all the described North and most South American species in the lack of genal processes. From C. duvauae (ScoIJ) and C. venusta (Tuthill) , the 2 South American species, which also lack genal processes, it diFers in the apically subacute rather than broadly rounded forewings and in details of the male and female terminalia. From all American species it diFers also in the host genus. Outside America, there is only 1 described Calophya species associated with Spondias , namely, Calophya spondiasae (crawford) from India and Sri Lanka associated with Spondias pinnata (L. f.) Kurz. The 2 species share the lack of genal processes but diFer considerably in details of the forewings and male and female terminalia suggesljng that they are phylogeneljcally not closely related.

Adults of C. spondiadis diFer from the other 2 known Mexican spe- cies in the completely black head and pronotum, the lack of genal processes, and the apically subangular forewings. Calophya dicksoni and C. schini have yellow or brown elements on the head and pronotum, bear narrow conical genal processes that are at least half as long as the vertex along the median suture, and possess apically broadly rounded forewings. In body size, C. spondiadis is intermediate between the slightly smaller C. dicksoni and the slightly larger C. schini . The parameres of C. spondiadis and C. schini are similar, both lamellar and apically truncate; that of the former is, however, slightly broader and stronger widening towards the apex. The paramere of C. dicksoni is, in proFle,sickle-shaped with a pointed apex. The distal porljon of the aedeagus has a short basal stalk (about half of segment) in C. spondiadis and C. dicksoni but a long one (about two-thirds) in C. schini . The dorsal outline of the female procljger, in proFle, is hardly concave in C. spondiadis , disljnctly sinuous in C. dicksoni , and strongly concave in C. schini . The female subgenital plate is long in C. spondiadis and C. schini but short in C. dicksoni ; in C. spondiadis , the subgenital plate is trunctae apically, in C. schini subacute.

Fiπh instar immatures of C. spondiadis diFer from C. schini in the straight anterior head margin (bearing lobes in C. schini ), the weakly curved antenna (s-shaped in C. schini ), the broadly rounded humeral lobe of the forewing pads (narrowly rounded in C. schini ), and the diamond-shaped marginal setae on the forewing and hind wing pads, which are absent or very small and few in numbers (always developed, large, numerous, and densely spaced so that they touch each other in C. schini ). The immatures of C. dicksoni are unknown.

The presence of diamond-shaped marginal setae on the forewing and hind wing pads seems to be correlated with the presence of very long asperate processes on the head, thorax, wing pads, and abdomen, unlike C. californica where both forms (with or without the long asperate processes) possess marginal diamond-shape setae. Nisson (2011) demonstrated that the immatures of C. californica developing on the fruits of R. integrifolia possessed very long asperate processes on head, thorax, wing pads, and abdomen whereas those developing on leaves lack these processes. It is likely that the polymorphism observed in C. spondiadis is similarly regulated, but no informaljon is currently available to conFrm this. Calophya spondiadis is only the 2nd species in Psylloidea aπer C. californica where such polymorphism has been observed.

Discussion

Many species of Calophya induce either open or closed galls on their hosts. Calophya schini induces very characterisljc pit galls that can distort the enljre leaf when their numbers are high. Several spe- cies are known, however, that are free living and do not induce galls, e.g., C. dicksoni and C. spondiadis . Calophya spondiadis shows polymorphic immatures with respect to the absence or presence of long asperate processes on the head, thorax, wing pads, and abdomen. Host-induced polyphenism is documented only for C. californica ( Nisson 2011) . Whether the polymorphism of C. spondiadis results from host-induced polyphenism requires further invesljgaljon. Immatures of other Calophya species that do not induce galls should also be examined for polyphemism.

The 3 species of Calophya reported here from Mexico probably represent only a small porljon of the exisljng fauna judging from the number of species known from the USA ( Hodkinson 1988).
