description: Carposina ottawana Kearfott, 1907, revised status
Material examined. The type specimens are lost, and the lectotype designated by Klots (1942) could not be found (AMNH). Specimens collected by C.H. Young in Ottawa, Canada the two days following the collection of the type and co-types designated by Kearfott were examined (NMNH), along with the type of C. nicholsana Forbes, 1923, which was designated a synonym of C. n. ottawana by Davis (1969). In total, 25 specimens of C. ottawana stat. rev. were examined (UMRM, FSCA, MEM, NMNH).
Male genitalia (Fig. 1b). The terminal spines of the gnathos have 2–3 spines that are significantly larger than other spines in both length and diameter. The spines spiral anteriorly (towards the tegumen) and project laterally. The harpe is 3 times as long as broad and gradually tapering to a point with no apparent teeth or striations present. The harpe continues anterior-ventrally with a strong sclerotized structure that reaches the anterior margin of the valva (hrp.ex). The juxta is reduced to a short, broad, well sclerotized plate. The uncus has the upper edge with a strongly sclerotized margin and 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 strait and shorter than the harpe. The transtilla (tra) is broad where it attaches to the pedunculi and narrows at the midpoint. The saccus is short (~0.75× length of the harpe) but well developed and larger than that of C. sasakii.
Female genitalia (Fig. 2a, 3a). The ductus bursae has a large area that lacks sclerotization in the posterior third of its length and is without a bend. The corpus bursae, in situ, has a pair of forked signa (sig) positioned dorso-ventrally (1 top, 1 bottom). The posterior margin of A8 (pm-A8) strongly projects posteriorly with the opening of the ostium bursae at the tip of the projecting lobe (Fig. 3a). The ventral surface of sternite 8 has sclerotized folds (sf) that produce a valley extending anteriorly from the ostium.
Larva (Fig. 4a). The pinaculum of the lateral setal group (L group) on the prothorax is small, round, and located anterior to and below the spiracle. The thoracic shield has a narrow band of integument lacking granulations along lateral and posterior margins. The pinacula of the meso- and metathorax are small (1 to 1.5 times the diameter of spiracle on prothorax), with the dorsal setae (D1 and D2) on a common pinaculum, and the subdorsal setae (SD1 and SD2) on a common pinaculum. On the abdomen the lateral seta L3 is widely separated from L1 and L2, and it is positioned close to the subventral setae (SV group). The subventral pinacula of segments A3–A6 are absent, and there is no granulation of the integument in the area between SD1 and the spiracle on segment A7.
