### Introduction

The Coleophora fauna of Mexico is poorly known. In the World Catalogue of Insects (BALDIZZONE et al., 2006) only three species are mentioned from Mexico: Coleophora decipiens Walsingham, 1914, C. mexicana Landry, 1994 and C. pelinopis Meyrick, 1933. The material dealt with in this paper mainly originated from the collection of the Essig Museum of Entomology, University of California, Berkely. It was collected during expeditions in the sixties, seventies and eighties of the twentieth century. The order in which the species are represented roughly follows Toll’s systematic group system. In spite of the fact that Toll’s system is based on palearctic species only and should be replaced by a more modern system, it is still useful. This is proven by the circumstance that most species described in this paper can be attributed to Toll’s 30th group.

All specimens treated in this paper are deposited in the Essig Museum of Entomology, The University of California, Berkely.

Material examined: MEX: Veracruz, 2 mi. W., El Joyita, 2230 m., Hwy H 140, 22-VIII-1977, E. I. Schlinger, gen.prep. ♀ Wf 12047; 1 ♀ MEX: Veracruz, 6 mi. SE Rinconada, 30-IX-[19]75 at light, J. Powell & J. Chemsak collectors, 1 ex. without abdomen; MEXICO: Veracruz, Coscomatepec NE, 9-VII- [19]75, J. A. Chemsak & J. Powell”

Diagnosis: The specimens exactly correspond with the description of Coleophora mexicana Landry, 1994, a species described after one male specimen collected at Gomes Farias, Tamaulipas, Mexico (LANDRY, 1994). According to Landry the species most likely belongs to the ramitella group of metallic-green Coleophoridae, and is closely related to C. timarella Landry & Wright, 1993. The female genitalia are here described for the first time.

Description female genitalia (Fig. 34): Papillae anales long, slender. Apophyses posteriores 1,5 times longer than anteriores. Sterigma subtrapezoid, medially excavated; caudal margin with strong bristles. Ostium bursae cup-shaped, almost as wide as sterigma, gradually narrowing into a transparent ductus bursae with central line; at 2/6 a chitinous sleeve with tiny spikes, at 5/6 a slightly chitinised convolution, at 6/6 a transparent section with very tiny spikes followed by an ovoid bursa; a thorn-like signum on an indistinct basal plate, and a small rasp-like signum.

Distribution: The specimens were collected at three different localities in Veracruz; the holotype was collected in Tamaulipas, the Mexican state north of Veracruz.

Bionomy: The early stages and the foodplant are not known.

Description: Wingspan 14 mm. Head snow-white. Labial palp white, second segment twice length third, which is tinged yellowish. Antenna without scale tuft; flagellum white, strongly ringed black. Forewing snow-white. Fringes greyish-white. Hindwing light grey. Fringes light grey.

Male genitalia (Fig. 30): Gnathos knob conical. Tegumen stretched, narrow, medially strongly constricted. Pedunculus long, broadly rounded. Valvula rounded, with strong bristles, and with a long acute process directed towards cucullus. Cucullus narrow, gradually widening towards rounded apex. Sacculus gradually narrowing towards a blunt triangular process. This process is strongly chitinized, with a strong tooth on its dorsal margin. On the border of the process and the sacculus are about 10 parallel chitinized ridges. Phallotheca broad, gradually tapering towards a blunt apex halfway the cucullus. Cornuti a sinuous bundle of long spines.

Bionomy: The species flies in September at an altitude of 2230 meters. The early stages and the foodplant are unknown.

Distribution: Only known from the type locality: The Mexican State of Coahuila.

Etymology: The name iztac refers to the colour of the forewing: Nahuatl: iztac= white.

#### Coleophora incerta van der Wolf, sp. n. (Fig. 15)

Holotype ♂: MEX., Sin[aloa], El Palmito, 15 mi. W. 18-VII-[19]64, J. A. Chemsak, J. Powell, black and white lights, gen. prep. Wf 12179.

Diagnosis: A species characterized by differently coloured streaks along the forewing. It is difficult to attribute the species to a related group.

Description: Wingspan 16 mm. Head white. Antenna white, scape white without scale tuft. Labial palp white, third segment about as long as second. Forewing light yellow with narrow white costal streak; a brown wedge-shaped streak from root to apex, and a narrow brown streak along dorsum. Fringes brown. Hindwing grey-brown. Fringes grey.

Male genitalia (Fig. 31): Gnathos knob globular. Tegumen narrow, medially constricted. Pedunculus slender. Transtilla large, rhomboid. Valvula inconspicuous. Cucullus of medium length, broad, with rounded apex. Sacculus with slightly convex ventral margin ending in a hook-shaped dorsal process, at its root a triangular flap. Phallotheca heavily sclerotized, stout, gradually tapering towards an obtuse apex. Cornuti a short bundle of spikes.

Bionomy: The species flies in July. The early stages and the foodplant are unknown.

Distribution: The species is only known from the Mexican State of Sinaloa.

Etymology: The name of the species reflects its dubious systematic position. (Latin incertus = dubious).

#### Coleophora mexicocopa van der Wolf, sp. n. (Fig. 16)

Holotype ♂: MEXICO, Puebla 2 mi SW Tehuacan, 5300, 5-X-[19]75, blacklight trap J. Powell collector, gen.prep. Wf 12142. Paratypes: 1 ♂, same data, gen.prep. Wf 12140; 1 ♂, same data, but X-4-75, gen.prep. Wf 12145.

Diagnosis: A medium-sized species with yellowish-white forewings. The systematic position of this species cannot be ascertained. In the male genitalia the species is characterized by the very short and inconspicuous cucullus, the large triangular dorsal process of the sacculus and the peculiar slender, crooked processes issuing from the transtilla.

Description: Wingspan 11-12 mm. Head whitish. Labial palp: second segment white, third segment yellowish, 1/3rd length second. Antenna: scape white, without tuft. Flagellum ringed white and black. Forewing whitish, gradually turning yellowish towards apex. Fringes beige. Hindwing greyish-white. Fringes beige.

Male genitalia (Fig. 32): Gnathos knob globular. Tegumen broad, medially not constricted. Pedunculus broad, rounded. Transtilla linear, slender, on each distal end a slender crooked process. Valvula large, rounded, inconspicuous. Cucullus transparent, rather short, gradually tapering into an acute more sclerotized apex. Sacculus broad, ventral margin convex, issuing into a triangular ventral process, at the root with a finger-like process. Dorsal process large, triangular, surpassing the cucullus, at its dorsal margin an acute triangular process. Cornutus dagger-shaped.

Bionomy: The species flies in October at an altitude of 1780 meters. The early stages and the foodplant are unknown.

Distribution: Only known from Tehuacan in the Mexican State of Puebla.

Etymology: The name mexicocopa is the Nahuatl word for “mexican”.

### Acknowledgments

I wish to express my thanks to Jerry Powell and Peter Oboyski of EMEC for allowing me to study the Mexican Coleophoridae in their collection. I also thank Dr. Cees Gielis for photographing most of the imagos. Also a word of thanks for Dr. Antonio Vives for kindly translating the abstract into Spanish. Last but not least I thank my wife Wil van der Wolf-van Dalen for helping me with the Nahuatl names.
