Stenolechiodes Elsner

Stenolechiodes Elsner, 1995 [1996]: 74.

Type species: Stenolechiodes pseudogemmellus Elsner, 1995 [1996].

Description. Imago. Labial palpus with third segment shorter than second. Clypeus with ventral margin rounded. Antenna simple, longer than half forewing length. Ocellus absent. Posterior area of sitophore with four campaniform sensilla not arranged in a trapezoid; anterior area with four campaniform sensilla ( Fig. 6 ). Forewing (length/width ratio 4.3) with small tufts of raised scales; R4 and R5 stalked, R4+5 and M1 stalked, M2 and M3 connate, CuA1 and CuA2 present; median fascia directed from apex of costa toward posterior margin. Hindwing (length/width ratio 5.8) with M1, M2, and M3 separate, M3 and CuA1 connate. Male with pair of hair pencil between abdominal segment II and III; sternum VIII with two broad posterolateral lobes; tergum VIII small, lingulate.

Male genitalia: uncus rounded apically, subequal in length with gnathos; ventral part of gnathos cushionlike, apex with dentate projections, without basal articulation, dorsal part absent; tegumen slender, narrower mesially than basally, longer than length of valva; valva divided into distally curved costa and setose, elongate, lightly sclerotized sacculus; tegumen basal width/length ratio 0.4; vinculum strongly projecting; saccus strongly fused with ventrobasal part of phallus; phallus without cornuti.

Female genitalia: apophyses anteriores about 2 x length of abdominal segment VIII; ostium bursae membranous, funnel shaped; antrum indistinct; ductus bursae extending to apices of apophyses anteriores; corpus bursae small; signum absent.

Larva. Undescribed.

Pupa. Undescribed.

Diagnosis. Stenolechiodes resembles Parastenolechia in the wing pattern and some male genital characters, but can be distinguished by the presence of CuA 1 in the hindwing and the absence of a signum in the female genitalia.

Hosts. Fagaceae : Quercus spp. ( S. macrolepiellus , S. pseudogemmellus ). ( Elsner 1995 [1996]; Huemer and Karsholt 1999).

Diversity and distribution. The two species of Stenolechiodes occur in Europe ( Huemer and Karsholt 1999; Huisman and Koster 2000).
