Peck — Leiodidae 
53 
elev., Ber 120 (dryish leaf litter at tree base, 21 pounds, 40 liters), 
1 male and female with long wings, 3 males and 3 females with 
short wings. St. Elizabeth Parish: Southfield, 16.V.1950, H. B. 
Mills, 1 long wing female (INHS). St. Thomas Parish: Corn 
Puss Gap, n.v.1950, H. B. Mills, 1 male and 1 female short wing, 
1 long wing male. Trelawney Parish: Drip Cave (1 1/2 mi SSE 
Stewart Town), 2.vi.68, Peck & Fiske, 13 males, 16 females, all 
with short wings, from moist guano. 
The data show the species to be present in caves and forest litter 
at low and middle elevations. The cave populations are all short 
winged. Forest litter populations contain long and short winged 
males and females. The sample is inadequate to compute the rela- 
tive frequency of short wings in the litter populations and any pos- 
sible relationship to sex. Wing dimorphism has not been noted 
for other members of the genus. The species is syntopic with the 
following, for both species were collected in Berlese sample 118, 
and at Corn Puss Gap. 
Aglyptinus jamaicensis n. sp. 
Holotype, male (in MCZ, type # 32003). Locality and data. 
Jamaica; St. Ann Parish, 2.5 mi S Moneague, 3.VL1968, S. Peck 
and A. Fiske, 2250' elev., Ber 118 (rotted logs in forest, 88 pounds, 
81 liters). Paratypes, 5 males and 9 females with same data; and 
2 males, 2 females, St. Thomas Parish, Corn Puss Gap, n.v.1950, 
H. B. Mills (INHS). 
Description. Length 1.1-1.5 mm. Color piceous. Eyes and wings 
normal. Head, prothorax, and elytra with fine and scattered hairs 
and punctures. Aedeagus (fig. 5) broad at base, gradually tapering 
and curving; in dorsal view (fig. 6) tip broad and narrowing 
rapidly to apex. Parameres short, thin, bent at tips. 
Diagnosis. The characters of the aedegus separate the species 
from all others. 
Variation. In some specimens the aedeagus is narrower at the 
tip and narrower in the center in the lateral view than illustrated. 
There is, nevertheless, a clear gap in shape between this and the 
preceding species. 
Habits. This and the preceding species are syntopic. This spe- 
cies was not found in caves or lowland forest litter. It may be more 
common in the higher elevation forests, where I did not extensively 
collect.
