Comprehensive Description

Cameraria tildeni

DIAGNOSIS.—This species resembles C. sempervirensella closely in genital morphology and biology, but differs markedly in adult maculation. In C. tildeni the dorsum of the thorax is golden brown (versus white in C. sempervirensella), and the white transverse fasciae of the forewings are more irregular and discontinuous than those of C. sempervirensella. The male genitalia of the two species appear to differ slightly, with the sacculus being more reduced in C. tildeni.

MALE.—Length of forewing: 4.2 mm.

Head: As described for C. sempervirensella except labial palpus with black more extensive. Vertex with orange-brown scales anteriorly and white scales posteriorly.

Thorax: Dorsum bronzy golden brown; tegula golden brown with some white scaling posteriorly.

Forewing: Ground bronzy golden brown; four irregular, partially broken, transverse fasciae present at base, antemedian, median, and postmedian positions; all four fasciae white, distally edged by a thin line of dark scales, and partially invaded basally by ground color; median fascia the most acute; postmedian fascia incomplete, broken at middle with costal portion confluent with crescent-shaped subapical white streak; a subapical patch of black-tipped white scales immediately distad to postmedial fascia.

Hind Wing and Abdomen: As described for C. sempervirensella.

Genitalia: As in Figure 95 (drawn from PAO 176). Valvae with sacculus reduced, gradually tapering to long, narrow, and slightly curved cucullus; a prominent digitate lobe arising from outer third of valvae. Eighth sternite with caudal lobes less rounded than in C. sempervirensella.

FEMALE.—Length of forewing: 3.8–4.2 mm. As described for male except genitalia as in Figure 130 (drawn from DRD 3014). Genitalia as described for C. sempervirensella.

TYPE MATERIAL.—Holotype: , King Mt., San Mateo Co., California; 26 mar 1946, J.W. Tilden, slide PAO 176; deposited in the California Academy of Sciences on indefinite loan from the University of California, Berkeley.

Allotype: , same data as holotype except: 13 Apr 1946 (em. 19 Apr 1946), reared Castanopsis (= Chrysolepis chrysophylla). UCB.

Paratype: 1 specimen. Same data as holotype except: 1, 13 Apr 1946 (em. 24 Apr 1946), reared Castanopsis, slide DRD 3014. UCB.

HOST.—Chrysolepis chrysophylla (Douglas ex Hooker) Hjelmquist.

MINE.—Shape oblong-ovoid; epidermis opaque, yellow green; most mines cross midrib (4 of 6); only mature mine with a single fold; dimensions with respect to leaf axis are: longitudinal, 2.88 cm; latitudinal, 1.80 cm.

LIFE HISTORY.—The seasonal timing of Cameraria tildeni's life cycle is unknown, but is presumed to be very similar to that of Cameraria sempervirensella, whose host is congeneric with that of C. tildeni.

ETYMOLOGY.—This new species is named in honor of Dr. J. W. Tilden of San Jose, California, who has been the only entomologist to collect this insect thus far.

Cameraria tildeni

provided by wikipedia EN

Cameraria tildeni is a moth of the family Gracillariidae. It is known from California, United States.[2]

The length of the forewings is 3.8-4.2 mm.

The larvae feed on Chrysolepis chrysophylla. They mine the leaves of their host plant. The mine is oblong to ovoid and the epidermis is opaque, yellow green. Most mines cross the midrib and only mature mines have a single fold.

Etymology

The species is named in honor of Dr. J. W. Tilden of San Jose, California, who has been the only entomologist to collect this insect when it was described.
