Acalyptris species 29135, in Puplesis & Robinson 2000: 53–54.

Diagnosis. The new species is distinguishable from all other Neotropical Acalyptris by the combination of a densely speckled thorax and forewing ( Fig. 38 ), wide, truncated pseuduncus ( Fig. 41 ), and unique, spine-like carinae of phallus ( Figs 39, 40 ).

Description. Male ( Fig. 38 ). Forewing length about 2.3 mm; wingspan 5.1 mm (n = 1). For full description see Puplesis & Robinson 2000: 53.

Abdomen. Male genitalia ( Figs 39–42 ) with capsule much longer (ca 380 μm) than wide (ca 245 μm). Pseudun- cus large, truncated. Valva simple, with a transtilla. Phallus ( Figs 39, 40 ) about 390 μm long; maximal width at apex 75 μm, without unique carinae, without cornuti.

Female. Unknown.

Bionomics. Host plant is unknown. Adults fly in April (single male was attracted to a light trap). Otherwise, biology is unknown.

Distribution ( Fig. 1 ). This species occurs in Chiquibul Forest Reserve in Belize.

Etymology. The species is named after Jarek Jagela (Vilnius, Lithuania), with our compassion for his uncurable illness.
