Thrixopelma lagunas sp. n. is the
fourth species of the genus distributed
in Peru. It is characterized by
a prolonged embolus in the male
(fig.4-5) and very simple receptacula
seminis in the female (fig.
9). The scopula of metatarsus III
extends over a third of the segment
only. In T. pruriens Schmidt,
1998 it covers 2/3, in T. cyaneolum
Schmidt, Friebolin & Friebolin,
2005 and in T. ockerti Schmidt,
1994, 1/2 of the metatarsus III. It
differs by its dark brown colour
from T. cyaneolum which shows
a cyan brightness of carapace and
extremities and from T. ockerti by
its spermathecae which are pointed-
caplike. The new species is
closely related to T. pruriens also
distri-buted in Peru.
Chilocosmia barenst9ineraels a new species of the genus and the first species
of this genus from Kalimantan. hi adult female could be c:cllected In the
South of Kalimantan, the Indonesian part of Borneo. It moulted on 20"
August 2009. The male of this species is unknown.
The exuvia has been studied by SCHMIDT who dissected the stridulation
bristles and the sperrnathecae. The new species differs from all other spa...
des of the genus by two additional rows of paddle and peglike strXluialing
setae on the maxillae, one medium-sized and one very small. The differ·
ences to C. p6erbooml SCHMIDT. 1999 from the island of Negros (Philippines)
are besides two additional rows of paddle and peglike setae on maxillae,
scopula of metatarsus IV the base of the segment not reaching, Tibia IV
not thickened, distance ALE-PLE considerably larger, unpaired third claw
absent, three pairs of sternal slgillae. hair red brown . Colour after moulting
deep black. The biotope Is the tropical rain forest. whictt is very humid during
the monsoon time. Ch//ocosmia SCHMIDT & VON WIRTH, 1992, in 2000
synonymized with Sel9nocosmia by RAVEN is a genus of its own and quite
different from Selenocosmia AUSSERER,1871 .
-Selenocosmia bom908nsis- nomen nudum (non vidimus) is probably an
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
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
The female of a new Haplopelma sp. from South-East Asia is described. It belongs to the H. minax group. Its simple fused spermathecae (fig. 1) cannot be distinguished from those of H. minax (THORELL, 1897) and H. Iividum SMITH, 1996. Leg IV is a little longer than leg I. The position of the thorn-like coxal spines on the prolateral face of the palp and their size are quite different from those of the other species of the H. minax-group (fig. 2). The male is known, but could not be studied. The species name H. vonwirthi sp. n. is proposed.
The male of Aenigmarachne sinapophysis from Costa Rica is described. It is a small theraphosinae species belonging to the group where type VI urticating hairs are present. These spiders are distributed in Mexico and Central America. A. sinapophysis is the only species where the urticating hairs of that type are distally bent. In A. sinapophysis tibial spurs are absent. This species has a very long and bent embolus. The female is unknown. Therefore the relationship to other Central American genera of Theraphosinae has to remain vague for the time being.
A well known Brachypelma
sp. often mistakenly called Aphonopelma pallidum
(F.O.P.-CAMBRIDGE, 1897) by some tarantula keepers and arachnologists, portrayed by VERDEZ in 2001 and by KLAAS in 2003 has proved being undescribed up to now. Males and females are almost entirely black with red and red orange setae on the dorsal face of the opisthosoma and the legs. In the females one can see a quite black triangle on the anterior face of the carapace as in B. emilia (WHITE, 1856). The species here described is named B. verdezi in honour of the French arachnologist J.M.VERDEZ who recognized the first that it is an undescribed Brachypelma
The genus Stenotarsus gen. nov. closely related to Aphonopelma Pocock, 1901 is established for South American species formerly desgnated as Eurypelma group A according to SIMON 1892 where metatarsus I containing many spines is as long as or not as long as tibia I. It differs from Aphonopelma by a procurved fovea (fig. 13), urticating hairs of type 1 and 3, a distally widened embolus (fig. 3) and spermathecae widely fused (fig. 19 - 21) with two little heads of different shape. S scissistylus is a medium-sized species. It's embolus appears deeply rutted (fig. 4) The relations to other species living in the Guyanas, North Brazil and Venezuela are discussed.
This new species differs from all other Theraphosinae by the following combination: labium
with long setae, cuspules almost on the front edge only, scopula of tarsus IV divided by a
band of setae, pad of feathered hairs retrolaterally on femur IV, in females urticating hairs of type I (fig. 1)containing barbs that change their direction twice, in males urticating hairs of type III. Palpal bulb similar to that of Lasiodorides SCHMIDT & BISCHOFF, 1997 (fig. 3), tibial spurs (fig. 4), receptacula seminis with twin receptacles (fig. 6), habitus 8fig. 2 and fig. 5).
A new species of Eucratoscelas POCOCK, 1898, E. lenuitibialis sp. nov., is described. It differs from the two other species of this genus by a normal, not thickened tibi a IV and rounded secondary receptacula seminis instead of more or less elongated ones. lt is very
similar to species of Pterinochilus Pocock, 1897. A revised key of the Harpactirinae
The new genus Haplocosmia differs from all other genera of Selenocosmieae by an undivided
spermatheca resembling that of Haplopelma and the following combination : Third unpaired claw on tarsus IV, thornlike setae on chelicerae prolaterally, scopula on tarsi I,II parted, III divided by thin hairs, IV divided by setae, procurved fovea, procurved front row of eyes and butterknife?like stridulating setae on prolateral surface of maxillae.
The new Citharacanthus species differs from C. sclerothrix VALERIO, 1980 by its larger size and oblong PME. The receptacula seminis converge. Plumose stridulating bristles also on trochanter and femur of leg II.
The new theraphosid Megaphobema velvetosoma
n. sp. described in the paper from Ecuador is very closely related to Megaphobema robustu (Ausserer, 1875)
but differs by velvet-brown (female) respectively brown-blackish (male) colour. The ventral tibia spur bears a long spine spine-shaped process. the spermatheca is regurarly rounded.
Chaetopelma anatolicum is the first known Theraphosid spider from Turkey. It differs from all other species of this genus by its apically divided receptacles and by a comb on the tibial spur containing 17 longer spines in one row.
The new species belongs to the new genus Thrixopelma which differs from
Paraphysa Simon, 1892 by denticulated tarsal claws, absence of spikes on all
coxae which are present in Paraphysa manicata Simon, 1892 and absence of
basally situated spines on Metatarsus I, also present in Paraphysa manicata and
in the female of P. pulcherrimaklaasi Schmidt, 1991. T. ockerti sp. n. has a small
stripe builded by white plumose urticating hairs on femur of palps prolaterally
situated. Its spermatheca consists of two pointed-cap-like receptacula seminis.
The new Tapinauchenius species can be distinguished from T. gigas DI CAPORIACCO, 1954 by its shorter legs, other dentition of chelicera and the front row of eyes less weakly procurved. The spermathecae differs from that of T. plumipes (C. L. KOCH, 1842) by thicker receptacula seminis which end with 5 or 6 small ovoides instead of one knob as in other species of this genus.
The new species P. horrida differs from P. manicata by size, short teeth on
some of the paired claws and the shape of the spermathecae. Paraphysa
phrixotrichoides STRAND, 1907 and P. pulcherimaklaasi SCHMIDT,
1991 are transferred to Phrixotrichus.
The new species Brachypelmides klaasi
differs from all the species of the Brachypelma
genus by its sharply pointed embolus, its bipartite spermathecae and its fine bearing of plumose setae on femur IV. It is the first representative of a new genus.
On 1 July 1991, Klaas P. G. Schmidt was sent to a package containing South America and Central spiders (preserved in alcohol) and exuviae, among which also included two males of an unknown species of Brachypelma.
Since the beginning of 1989 a tarantula from New Guinea is imported to Germany, here and in England is sold under the name Selenocosmia lanipes Ausserer 1875. It differs
from the species of the genus by the Selenocosmia stridulations organ, the eye position
and the relative eyes Grobe. This is an undescribed species of the previously monotypic
Genus Selenotypus Pocock 1895, of which only the genotype, Selenotypus plurnipes Pocock 1895, the groBte Australian spider species from Queensland, was known.
Due to the finding of a second type, the genus diagnosis Mmust be extended.
