Teleiopsis Sattler

Teleiopsis Sattler, 1960: 66 .

Type species: Recurvaria diffinis Haworth, 1828 , by original designation.

Description. Imago (Fig. 64). Labial palpus with third segment subequal in length or shorter than second. Clypeus with ventral margin sinuate. Antenna simple, longer than half forewing length. Ocellus present. Posterior area of sitophore with four campaniform sensilla not in trapezoid; anterior area with eight or twelve campaniform sensilla. Forewing (length/width ratio 4.1) with tufts of raised scales, sometimes prominent; M1, M2, and M3 separate, CuA1 and CuA2 present; median fascia transverse or directed from base of costa toward posterior margin. Hindwing (length/width ratio 3.1) with R5 and M1 stalked, M2, M3, and CuA1 separate, CuA2 present. Male sternum VIII with posterolateral margin rounded; tergum VIII with two pairs of hair pencils, one pair on anterolateral margin and one pair on posterolateral lobes ( Fig. 23 ). Female abdominal segment VIII weakly sclerotized, with or without lateral pouches toward anterior margin of ostium bursae.

Male genitalia: uncus as long as length of tegumen, tapered at apex, subequal in length with gnathos; gnathos weak, lingulate, reduced to pair of basal arms in some species; valva divided into digitate shaped costa and variably shaped sacculus; tegumen basal width/length ratio 1.2; saccus reduced; phallus longer than length of tegumen, slender, base articulated with anterodorsal margin of vinculum, without cornuti.

Female genitalia ( Fig. 42 ): apophyses posteriores two-thirds to subequal length of abdomen; apophyses anteriores about 2– 3 x length of abdominal segment VIII; antrum large, well developed, funnel shaped to tubular; ductus bursae well differentiated from wider corpus bursae; signum diamond shaped or in form of cross with obtuse angles forming parallel sided extensions, with serrate margins and transverse median ridges.

Larva. Undescribed.

Pupa. Less than 6 mm in length; maxillary palpi touching or adjacent to genae; antenna adjacent to each other for about 3 x greater distance than length of visible ends of metathoracic legs; pronotum weakly narrowed, or narrower at middle by at least 1/3 than its greatest length; prothoracic legs separated from oculi; abdomen usually lacking setae ( Patoèka and Turcáni 2005).

Diagnosis. Teleiopsis species are relatively large sized relative to other genera in Teleiodini . This genus is superficially similar to Xenolechia , but it is easily distinguished by having both the costal and saccular parts of valva, the apex of uncus not bifid, and the ductus bursae without microtrichia.

Hosts. Anacardiaceae : Rhus coriaria L. ( T. latisacculus , T. terebinthinella ), Pistacia terebinthus L. ( T. latisacculus , T. terebinthinella ). Polygonaceae : Rumex spp. ( T. diffinis , T. rosalbella , T. albifemorella ), Oxyria digyna (L.) ( T. bagriotella ). ( Burmann 1977; Emmet 1988; Klimesch 1950, 1968; Mann 1862; Sattler 1982; Stainton 1854).

Diversity and distribution. Teleiopsis has nine species with one in North America and the remainder in Europe and Asia ( Hodges 1983; Huemer and Karsholt 1999; Pitkin 1988; Sattler 1982).
