SEVEN NEW LEPIDOPTEROUS LEAF-MINERS
ASSOCIATED WITH QUERCUS AGRIFOLIA
(HELIOZELIDAE, GRACILARIIDAE)
Paul A. Opler
Division of Entomology University of California, Berkeley
During the course of a study of the bionomics of Microlepidoptera associated with Quercus agrifolia Nee (Fagaceae) in California, it was found that a number of the species are undescribed. In order to provide names for use elsewhere, one new heliozelid and six new gracilariids are herein described. Because the genitalia of the Nearctic members of these families have not been previously studied, the works of Kumata (1963), Kuroko (1961), and Vari (1961) provided bases of homologies and diagnostic features in the genitalia of these moths.
Descriptions in this paper use the holotype and allotype as exemplars. The holotype and allotype of each species are deposited in the California Academy of Sciences, San Francisco, on indefinite loan from the California Insect Survey, University of California, Berkeley. Paratypes are deposited in the American Museum of Natural History, New York; California Academy of Sciences; California Insect Survey; Canadian National Collection, Ottawa; Los Angeles County Museum; and U.S. National Museum, Washington, D.C.
Coptodisca powellella Opler, new species
Male. Length of forewing 1.5 to 1.7 mm (reared).
Holotype male. Length of forewing 1.6 mm. Forewing: Basal half metallic silver; distal half with pattern as follows: a basal orange patch extending from costa almost to inner margin; followed distally by two opposing triangular patches of silver, one on costal margin, one on inner margin, apices not quite joining; these patches narrowly margined with black basally and distally; costal area orange distal to triangular patches except for subapical black margined silver patch and black apex. Dorsal area black distal to silver patch on inner margin. Abdomen: Blackish dor-sally, silver ventrally. Genitalia: As in Figs. 9, 10, 12, 14, 15 (drawings from para-type, PAO prep. 323); uncus shallowly bilobed at tip.
Female. Length of forewing 1.6 to 1.9 mm (reared).
Allotype female. Length of forewing 1.7 mm. External features as described for male. Genitalia: As in Figs. 28, 29, 30. Comparison with genitalia of other oak-feeding Coptodisca was not made. Thus, the included drawings serve only to portray the structures which may later prove to be of diagnostic value.

The only previously described western oak-feeding member of this genus is C. querciella Braun. In her description of C. querciella, Braun (1927) delineates only the maculation features of the adult and states that the host is an evergreen species of Quercus. Through Dr. Braun's courtesy I was able to examine leaf mines as well as a male paratype from Cornville, Yavapai County, Arizona, the type locality. The leaf which harbored the mines of C. querciella proved to be Quercus emoryi, a species which is consubgeneric with the hosts of C. powellella.
C. powellella differs from C. querciella in features of forewing maculation. The former has extensive orange markings and restricted black markings, while the latter has less extensive orange and more extensive black (Figs. 2, 4).
The most obvious differences in the male genitalia are in the aedeagi and apparent aedeagal sheaths of the two species. The "aedeagal sheath" of C. powellella is proportionately larger than that of C. querciella and

Acrocercops insulariella differs from A. affinis Braun (1918), the only previously described oak-feeding species which occurs in the west, by features of forewing macula tion and the male genitalia. Through the courtesy of Dr. Braun I was able to examine male and female paratypes from Camp Baldy, San Bernardino County, California, the type locality.
Although the two species are closely related there; are slight but constant differences. The forewing of A. affinis has a pale white patch on the inner margin two-fifths from the base which has quadrate darkened patches to either side. These features are not present in individuals of A. insulariella.

Neurobathra bohaHieUa is apparently the only representative of the genus in California. Neurohathra strigifinitella (Clemens), the only other described species in the genus, occurs in eastern North America. The genitalia of IV. bohartiella differ from that of N. strigifinitella as figured by Vari (1961) as follows: the costal margin of the valva of N. bohartiella is straight while that on N. strigifinitella is slightly concave. Additionally the upper tooth on the distal margin of the valva is relatively smaller for IV. bohartiella than for IV. strigifinitella.
Volume 25, Number 3

The life cycles of the two species differ in that pupae of N. strigifinitella undergo an obligatory pupal diapause (fide T. N. Freeman), while the life cycle of N. bohartiella lacks any form of diapause.

Caloptilia agrifolia can be distinguished from Caloptilia reticulata (Braun), the only other described oak-feeding species of the genus occurring in California, on the basis of life cycle features, larval shelter, maculation, and genitalia. C. agrifaliella is normally single-brooded, but is facultatively double-brooded, feeds only on young foliage, and has a pupal diapause which usually lasts through the summer, fall and winter. The larval shelter is a rolled leaf. C. reticulata is homodynamically multiple-brooded, feeds on older foliage, and lacks any type of diapause. The larval shelter consists of a singly folded leaf. The vestiture on the dorsum of the thorax and tegulae of C. agrifoliella is unicolorous; and the fore-wing is variously colored orangish, tan, or rust colored with faint light areas and black marks. The male genitalia is distinguished by the long acuminate saccus, rounded valvae, and triangulate tegumen. The vestiture on the dorsum of the thorax of C. reticulata is reddish-orange, while that of the tegulae is straw-colored, and the forewing is reddish-orange with numerous straw-colored splotches. The male genitalia are distinguished by the short saccus, truncated valvae, and rounded tegumen.
The names Gracilaria sanguinella Beutenmiiller, Gracilaria nigristrigella Beutenmiiller, Gracilaria ruptistrigella Beutenmiiller, Gracilaria shasiella Beutenmiiller described in 1888, and Gracilaria fuscoochrella Beutenmiiller described in 1889 were synonymized by Ely (1917) under Gracilaria alnivorella Chambers. McDunnough (1946) restricted the name alnivorella to an alder feeding species of eastern North America and did not include Beutenmiiller's names in the synonymy of that species.
Remnants of the Beutenmiiller holotypes are located in the U.S. National Museum and were examined by J. A. Powell. The present state of these types is as follows:
G. sanguinella—"1358 California/' No abdomen. No host given.
G. nigristrigella—"1333 California." All that remains of the type is one
hind wing. Collected on oak tree. G. ruptistrigella—"1327 California." The specimen is broken in half.
No host given. G. shastella—No abdomen. No host given. G. fuscoochrella—No abdomen. No host given.
These names could apply to any of a number of Californian Caloptilia species which feed on Acer, Alnus, Lithocarpus, or Quercus. Because features of the genitalia and host plant are the main criteria for assigning specific status to the moths of this genus and because the above listed Beutenmiiller names cannot be evaluated on either basis, I treat them as nomena dubia.

Its life history, maculation, and genitalic features set Lithocolletis antiochella apart from all other members of the genus. Among the species treated by Braun (1908) in her revision of the North American Lithocolletis, Lithocolletis diaphanella Frey and Boll appears to be most closely related in external appearance to L. antiochella. L. antiochella differs from L. diaphanella in that the vestiture of the palpi, antennae, and vertex are brown, not white; that there are three dorsal white streaks instead of two; and that the forewings are brown in color as opposed to

golden brown. A comparison of the genitalia of these species was not carried out.
The male genitalia of L. antiochella have a well sclerotized diaphragma, asymmetrical valvae which are broader distally than basally. The eighth abdominal segment of the female is completely membranous.
The larvae feed on young foliage in the spring and then undergo a pupal diapause of about ten months.

with which L. sandraella should be compared. Both L. sandraella and L. inusitatella have Quercus agrifolia and Q. wislizenii as their only hosts. L. sandraella lacks the metallic bronze sheen and apical black spot displayed by the forewings of L. inusitatella. L. sandraella differs strikingly from L. inusitatella in genitalic features as well. The valvae of L. sandraella are symmetrical while those of L. inusitatella are asymmetrical. Additionally, L. sandraella is bivoltine, while L. inusitatella is univoltine.

Among described species of the genus, the closest relative of Cameraria wislizeniella is Cameraria medio dor sella (Braun). These moths are very similar in maculation and are difficult to separate on that basis, but the two have distinctive male genitalia. The male genitalia of C. wislizeniella differs by the distally expanded valvae, the relatively uncurved aedeagus, and the attenuate flap of the ninth sternite.
The life cycle of C. ivislizeniella is typified by the absence of diapause while that of C. medio dor sella has a pupal diapause over the winter months.

ANTONIE JOHANNES THEODORUS JANSE 1877-1970
On June 12th, 1970, at the age of ninety-three, Dr. A. J. T. Janse, a great Lepidop-terist and a man of remarkable learning and ability, passed away. For almost seventy years he collected, reared, studied, and described Lepidoptera, a privilege given to very few. All by himself, he built up a unique collection of the Heterocera of southern Africa.
