Most similar to C. franclemonti ; see diagnosis under that species. Description . Sexes externally alike, except females slightly larger than males. FW length averages 18 mm in males, 19 mm in females. Head, thorax, abdomen – as for C. franclemonti , with following differences in wing markings: Forewings slightly paler grey overall, particularly distal third; medial dark area slightly paler; hindwing with slightly paler yellowish base, dark marginal band on average slightly wider than in C. franclemonti . Male genitalia (Fig. 24) – structurally very similar to that of C. franclemonti , with following differences: valve tip slightly more triangular (more squared in C. franclemonti ); base of vesica with two large, thorn-like cornuti positioned adjacent to each other on left-sublateral area. Female genitalia (Fig. 31) – as in C. franclemonti , with following differences: antevaginal plate with broad Ushaped medial notch and two short, broadly-rounded triangular lobes, not extending beyond margin of sternum; ductus bursae with a more pronounced ventral twist of right lateral margin. Distribution and biology. The known distribution of C. tapa is limited to the Chiricahua, Huachuca, and Santa Rita Mountains of southeastern Arizona, although the species probably occurs in adjacent parts of Mexico . Th e main flight period is from September to October; a single specimen from early May indicates there may be spring flight. Larvae have been reared on Gambel Oak ( Quercus gambelii ). Remarks . Although previously treated as such, neither C. tapa nor C. franclemonti is referable to C. pata , as pointed out in the ‘remarks’ section of C. pata .
