Psalmopoeus langenbucheri sp. n. differs from most Psalmopoeus spew
des yet known in its small size. The body length of the female (holotype) is
37,0 mm and of the male 21 ,5 mm (without chelicera and spinnerets). Its
pal pal bulb with the long and thin embolus is similar to that of some species
of Tapinauchenius , its length is 3,5 mm. In the female the length of the
receptacula seminis is 1,6 mm, the spermathecae belong to the P. reduncus-
type. There are some differences between the spermathecae of subadult and
adult females.

Avicularia hirschii is one of the smaller species of the genus. The male has instead of a tibia spur a lot of thick black spines similar to those of
Avicularia versicolor (Walckenaer, 1837) from Martinique and Guadeloupe. Tufts of red hairs on the tarsi and the opisthosoma arranged in two rows framing the black middle section are typical. The length of the urticating hairs of type II is 0,10 - 0,17 mm. The embolus is long and tapered. The spermathecae are similar to those of
A. azuraklaasi Tesmoingt, 1996 from Peru. Juvenile spiders are almost white coloured with black stripe on the opisthosoma. There is no Christmas tree pattern as in other
Avicularia species.
