Subfamily Catopinae 
Dissochaetus jamaicensis n. sp. 
Holotype, male (in Museum Comparative Zoology, Harvard, 
MCZ type #32005). Type locality and data. Jamaica; St. An- 
drew-Portland Parishes, Hardwar Gap, 4000' elev., 31.iii-9.iv. 
1968, S. Peck, A. Fiske leg., carrion trap. Paratypes, 104 with 
same data. 
Description. 2. 3-2. 8 mm long. 1 .2-1.5 mm wide. Winged. 
Color dark brown, lighter on antennal base, legs, and anterior cen- 
ter of elytra. Eyes large. Antennae normal, reaching first 1/5 of 
elytra when laid back. Pronotum coarsely granulate; transverse, 
widest 1/3 from base, 1.5 times as wide as long; posterior angles 
obtuse. Elytra regularly rounded. Aedeagus (fig. 1) elongate, 
drawn out at apex, shorter than parameres, no lateral hairs. Para- 
meres thin, slightly enlarged and flattened at ends which curve to- 
ward each other, bearing 2 terminal setae. Internal sac armed, 
ligules absent. Genital segment (fig. 2) complete, longer than 
broad, sternite lobes thin and curved ; pleurite lobes thin, with a 
few long setae. 
Diagnosis and relationship. The species can easily be distinguished 
from all others by the characters of the aedeagus and the genital 
segment. The species belongs to the spinipes group of Jeannel (1936) 
because of its major metatarsal spur which is longer than the first 
metatarsomere, and of the characters of the aedeagus. This group 
contains the other known West Indian species of the genus. How- 
ever, since the group is distributed through all the lands bordering 
the Caribbean Sea, and the Gulf of Mexico, and the Dissochaetus 
fauna of most of this land is inadequately known, little about re- 
lationships or time or direction of migration can be said. 
Collections and habitat data. Most of the specimens came from 
carrion-baited pitfall traps set in the cloud forest of Hardwar Gap. 
This is a moist to wet forest at 4000' elevation, set aside as a forest 
reserve by the Jamaican Forest Service. Big trees are present on 
level ground, but much of the forest has a somewhat reduced stat- 
ure. Epiphytes and tree ferns are abundant. The litter appeared 
rich but was not sampled with Berlese funnels. The following traps 
were set in various parts of this forest along a new road that was 
under construction, leading down to the north shore. T 309, along
