Psyche

Aglyptinus dimorphicus n. sp. 
Holotype, male (in MCZ, type #32002). Locality and data. 
Jamaica; Trelawney Parish, Windsor Great Cave (at Windsor, 10 
mi S Falmouth), 5.iv.68, S. Peck & A. Fiske. Paratypes, 34 with 
same data. 
Description. Length 1.3- 1.5 mm. Color rufotestaceous to piceous. 
Epipleuron often light in dark specimens. Eyes normal. Head, 
prothorax, and elytra with fine and scattered punctures, and hairs. 
Wings dimorphic; of normal length and apparently functional, or 
reduced to 3/4 the length of the elytra and functionless. Aedeagus 
(fig. 3) long, thin, curved, sinusoidal at tip; in dorsal view (fig. 4), 
tip thin and pointed. Parameres thin, straight, about 2/5 length of 
aedeagus. 
Diagnosis. The wing dimorphism and characters of the aedea- 
gus separate the species from others. 
Variation. The aedeagus in some specimens is sometimes slightly 
broader in the middle and not quite so curved as illustrated in the 
lateral view. Wing dimorphism data are below.
