Aglyptinus puertoricensis n. sp. 
Holotype, male (in MCZ, type #32004). Locality and data. 
Puerto Rico; Toro Negro Forest, Cerro Dona Juana, 1000 m elev., 
28.xii. 1 966-4^.1967, S. Peck, yeast bait trap. Paratypes, 1 male 
and 2 females with above data; 1 male and 2 females, Puerto Rico, 
Luquillo Experimental Forest, 300 m elev., 26.xii. 1966-1.1.1967, 
S. Peck, yeast trap; 1 male, Puerto Rico, Maricao State Forest, 
i.vii.1958, M. W. Sanderson, beating and sweeping (INHS). 
Description. 1.4- 1.7 mm. Color piceous. Eyes and wings nor- 
mal. Head, prothorax, and elytra with fine and scattered punc- 
tures and hairs. Aedeagus (fig. 7) broadest at base, narrowing and 
curving to middle, from middle to tip straight, gradually narrowing 
to tip; in dorsal view (fig. 8), tip pointed, narrowing towards mid- 
dle. Parameres straight, with constriction near middle, 1/3 length 
of aedeagus. 
Diagnosis. The characters of the aedeagus separate the species 
from all others. 
Habits. The species is undoubtedly more widely distributed in 
Puerto Rican forests and would be frequently found by using Ber- 
lese funnels, which I did not use in Puerto Rico. It was not found 
in the 11 caves I visited. 
Genus Creagrophorus Matthews 
Diagnosis. Body hemispherical; darkly colored; smooth and shin- 
ing. Size 1. 2-1. 75 mm. Eyes large. Antennal grooves distinct. An- 
tennae short; 11 segmented; club 5 segmented, compact, incrassate; 
club segments wider than long; segment eight patelliform, more 
short and narrow than seven and nine. Mesosternum vertical in 
front; without keel. Mesofemur broad, with or without hook on 
posterior margin. Mesotibia broad at apex, with excavation, more 
pronounced in male. Metafemur broad, normal in female, male 
with one or two hooks or teeth on posterior edge. Metatibia nor- 
mal. Tarsal formula 4-4-3, or 3-3-3. Abdomen with five ster- 
nites, the first forming a long, smooth, subtriangular plate. 
The genus is thoroughly described by Matthews (1888) who rec- 
ognized two species from Mexico and Panama. The following is 
the third known species. Matthews noted the close similarity of 
this genus to the eyeless Scotocryptini, which are inquilines in Meli- 
ponine bee nests. Only the Scotocryptini share with Creagrophorus 
the unusual shape of the first abdominal sternite. Matthews de- 
scribed Creagrophorus with a 4-4-3 tarsal formula and noted that
