Carposina sasakii Matsumura, 1900 View in CoL

Material examined. The deposition of the type is unknown. Eight specimens of C. sasakii from a rearing colony in Yokohama, Japan and four wild-caught specimens from Hokkaido, Ishikari, Japan were examined ( NMNH).

Male genitalia ( Fig. 1c View Figures 1–4 ). The terminal spines of the gnathos are uniform in diameter and length, and all project posteriorly. The harpe is long and tapering to an abrupt upturned point, with a narrow, sclerotized structure that continues anterior-ventrally to the margin of the valva. The juxta is reduced to a small brace-like structure that is narrowly sclerotized on the posterior margin. The uncus has the posterior margin strongly sclerotized, covered with long thin setae (removed in illustration) that are half the length of the arms of the gnathos. The basal process of the valva is straight and slightly longer than the harpe in length. The transtilla is very narrow, and the saccus is reduced to a small knob.

Female genitalia ( Fig. 2b, 3b View Figures 1–4 ). In the ductus bursae the basal third of its length has a large area that lacks sclerotization, and there is a distinct bend half way between the sinus vaginalis and corpus bursae. In situ, the corpus bursae has two-forked signa positioned laterally (one left, one right). The posterior margin of A8 barely projects posteriorly, with the opening of the ostium bursae located on the posterior margin ( Fig. 3b View Figures 1–4 ). The ventral surface of sternite 8 has sclerotized folds that produce a valley extending anteriorly from the ostium.

Larva ( Fig. 4b View Figures 1–4 ). The prothoracic pinaculum of the L group is large (four times the diameter of the spiracle along its longest axis) and extends below the spiracle. The spiracle is positioned on its own well defined pinaculum. The thoracic shield has granulated integument extending to the edge of the sclerotized plate. The pinacula of the meso- and metathorax are large and conspicuous (three times the diameter of spiracle on the prothorax), and all D and SD setae are on separate pinacula. On the abdomen, the pinacula of SD1 on segments A1–6 are noticeably larger than those of C. ottawana . Lateral seta L3 is widely separated from L1 and L2 and positioned close to the SV setae. The SV pinacula of segments A3–A6 are small but present. All abdominal spiracles are surrounded by a concolorous, unpigmented, unsclerotized ring that is free of granulation.
