tered in medial areas of the thorax, on the abdomen two pairs are present. Bilocular pores scattered. First two abdominal spiracles also present, situated on the dorsum. Dorsum: Two pairs of umbelliform setae are at the margin of each segment. On the middle of the thoracal segments of one pair of umbelliform setae are present. On the thorax two pairs of fimbriate setae are present, and on the abdomen one pair 59 pm long fimbriate setae are present. The mid-dorsum with some broad clavate setae. Anal ring developed, with six anal ring setae. Bilocular pores scattered on the middle part of the dorsum. Comments — The three larval stages, and the female could be easily separated according to the type, and number of setae on the venter and dorsum. Key to adult females of Carayonemidae 1.

ZOOGEOGRAPHIC CONSIDERATIONS With the data presented here, and considering earlier reports, the number of Carayonema species in the Neotropical Region has increased to four. One species (M. mexicoensis) is known only from Mexico, one species (B. costaricaensis) only from Costa Rica. Two species were found in Brazil (C. orousseti, F. monikae). An unidentified larval stage was published earlier by Richard (1986) from Peru (Fig. 7). These data show that members of this family could be found in other parts of the Neotropical Region. However, in the numerous samples from other parts of the World this family was not found, it cannot be excluded, that they are present in the rain forests of other tropical regions (Ethiopian, Oriental, Pacific), too. However special collecting methods should be used that enable to collect the insects from the surface of the water covering mosses, litter and soil of the rain forests. Fig. 7.
