Two new species of Rhopalovalva Kuznetsov (Lepidoptera: Tortricidae) from China Author Zhang, Aihuan Author Li, Houhun text Zootaxa 2010 2718 64 68 journal article 10.5281/zenodo.199790 9b573b6f-a10f-4a55-9a6e-8932f63c4d60 1175-5326 199790 Rhopalovalva triangulata Zhang & Li , sp. nov. Figs. 2, 5 Diagnosis. This species can be separated easily from its congeners by the nearly Y-shaped uncus, which is club-shaped in other species. Rhopalovalva triangulata shares with R. rhombea the absence of a long ventral process or spine on the cucullus, but the two can be distinguished by the shape of the cucullus: triangular in R. triangulata and rhomboid in R. rhombea . Description ( Fig. 2 ) . Head : Vertex with grayish brown scales; frons grayish white. Antenna light brown. Labial palpus gray; third segment porrect, concealed in long scales of second segment.

Forewing length 6.0 mm; forewing ground color gray, sprinkled with dark gray dots; apex protruded, falcate; fasciae ill-defined; basal fascia and subbasal fascia forming indistinct basal patch, extending from costal 1/4 to 1/3 of dorsum, protruded in middle on outer side, occupying ca. 1/4 of forewing; tornus with an elliptic gray spot; costa with nine pairs of white strigulae from base of wing to apex; strigulae 1–4 between base and the point where Sc meets costa; strigulae 5 and 6 between Sc and R1 ponits, each containing only one stria; distal three pairs distributed between pairs of veins R1–R2, R2–R3, R3–R4 respectively, confluent with each other and extending to termen; fringe grayish white. Hindwing and fringe gray. Abdomen : Male genitalia ( Fig. 5 ) with uncus somewhat Y-shaped, ca. 1/3 length of socius. Socius hairy, broad, long, gradually narrowed apically.
