Cirrothaumatia Razowski & Becker, 1986

Type species: Phalonia tornosema Clarke, 1968 , by original designation.

Diagnosis. Wing expanse range: 11.8–16.2 mm. The genus is distinguished by two features of the male genitalia: the lateral position of the socii and the presence of a tuft of androconial scales from the base of the valval sacculus; and two features of the female genitalia: a simple ostium and a large accessory bursa originating from the anterior portion of the bursa, proximate to the induction of the ductus seminalis ( Razowski and Becker, 1986) (however, one species lacks an accessory bursa). In the related genus Parirazona the saccular scale tuft is absent, and the socii do not originate from such a lateral position (Razowski 1984).

Biology. Unknown. Typical habitats for Cirrothaumatia species are tropical submontane forests ( Figs. 10–17 ), 600 to over 2000 m. The site in Venezuela (Rancho Grande) differs somewhat in being super-humid, while the site in northern Peru (Huembo Reserve) is a forest and bush dry habitat.

Distribution. Southern Mexico (Veracruz) to central Peru ( Fig. 18 ). Species of the genus must also be present in Colombia and possibly Bolivia, but the very few specimens known thus far from Mexico to Peru would indicate they are rarely encountered, or possibly are not particularly attracted to lights.

Discussion. An addition to the cryptic generic description of Razowski and Becker (1986) involves the presence of a cestum represented by a narrow, linear, carina-like sclerite extending from the caudal end of the bursa ( Figs. 4–5 , 7, 9 ), where it is slightly enlarged, along the ductus bursae caudally to near the colliculum-like band anterior to the antrum. When Razowski and Becker (1986) described the genus for C. tornosema , the linear carina-like cestum was not mentioned. Razowski (1994) also noted no cestum in his notes on C. tonocarpa (Meyrick) , a species he added to the genus which has a semicircular signum ( Fig. 8 ). Clarke (1968) also did not mention a cestum for the two species he described. Further study is needed to determine whether C. tornocarpa should be included in Cirrothaumatia because it has female genital features anomalous for the genus in its absent cestum and lack of a secondary bursa. The male genitalia appear similar to those of the two species for which males are known ( Fig. 7a, 9a ), so the male of C. tornocarpa needs to be re-examined to verify its generic assignment. The female genitalia of the three new species are very similar to those of C. tornosema and C. vesta , so they are undoubted members of Cirrothaumatia . All the new species of Cirrothaumatia have very similar wing maculation and head features ( Figs. 1–3 ), as do the three species known previously.
