This is an attempt, to characterize the genus Citharacanthus Pocock, 1901, with todays knowledgement. For this, we look at the historic developement within the systematic. A key to the today known species will be developed. Citharacanthus longipes niger FRANGANILLO, 1931 will be revised and get the status of a own kind. The future name is Citharacanthus niger FRANGANILLO, 1931, and Cyrtopholis sargi STRAND, 1907 is in future Citharacanthus sargi (STRAND, 1907). Also we discuss the position of Citharacanthus spinicrus (LATREILLE, 1818) this species has to be categorized as "nomen dubium incertae sedis". At the end we talk about the close relationships within their kind, for future work there is a key to easier identify both sexes.
A new species of Acanthopelma (Araneae: Theraphosidae)
from northern Belize is described, and is among the smallest
theraphosid spiders known. The new taxon is distinguished
from congenerics by an incrassate palpal tibia, preapical
embolar process and unmodified tibial spur in males, and a
unique abdominal pattern in females. Both sexes possess
unusually short medial segments of the posterior lateral
spinnerets. Data on meristic and morphometric character
variation and natural history notes are also presented.
The new Tapinauchenius species, T subcaeruleus n. sp. , is very similar to T
elenae Schmidt 1994, but differs in some peculiar features of its coloration. As in T elenae the receptacula seminis terminate in some ovoid structures instead of a knob as in other species of this genus.
The new theraphosid Pseudhapalopus spinulopalpus n. sp. described in this paper from Colombia, is closely related to Pseudhapalopus aculeatus (Strand 1907) from Bolivia, but differs in size and spinulation of palps and legs. The epigynum is similar to that of Cyclosternum.
A new species of Theraphosidae, Crypsidromus gutzkei, is described (from the male only )
from northern Belize . Unique coloration in combination with pedipalps of intermediate length distinguishe s
C. gutzkei from all congeners . Character states proposed as diagnostic for males of Crypsidromus Ausserer
1871 and Metriopelma Becker 1878 are combined in the male of this new species, supporting the maintenance
of Metriopelma in the synonymy of Crypsidromus.
The genus Holothele KARSCH, 1879 is revised. Stichoplastoris gen. nov. is established to Substitute Stichoplastus SIMON, 1889 which will not be available in future. Schismatothele KARSCH, 1879 will be revaluated as a genus of Theraphosidae. Euthycaelus SIMON, 1889 is also revaluated but placed into the family of Barychelidae. Proshapalopus MELLO-LEITAO, 1923 is removed from synonymy with Stichoplastus SIMON, 1889. Hemiercus SIMON, 1889 and Schismatothele KARSCH, 1879 are removed from synonymy with Holothele KARSCH, 1879. A key is added to all actually known species of Holothele as well as detailed descriptions of Holothele sericea SIMON, 1903 and Schismatothele lineata KARSCH, 1879. Diagnosis and drawings are given to qualify even non-specialists for identifying these taxa.
A new Chaetopelma-species from north-cyprus (Besparmak-mountain) is discribed.
It differs from other species of this genus by two very seperate receptacles
who thickin at the end, the structure of palpal bulb and a extrem short bodysize.
Ischnocolus gracilis (AUSSERER, 1871) is transfer to the genus Chaetopelma
(AUSSERER, 1871) and Chaetopelma aegyptiacum (AUSSERER, 1871) is
synonymy with Chaetopelma gracile.
n.sp. and Brachypelma hamorii
n.sp. (Mexico) show morphological differences with B. smithi
although visually closer to the latter. Spermathecae and copulatory organs of males are food for thought. Indeed, if the spermathecae of hamorii
are distinct, those of annitha
are not. On the other hand, in the copulatory organs and tibial apophysis, the opposite is true: where the bulbs and tibial apophysis of annitha
are distinct from smithi
, in contrast those of hamorii
are similar to the latter making it possible to consider including these as a subspecies in the genus.
Two new species of Aphonopelma from the Mojave Desert are described, A. joshua and
A. mojave. Four nominal species, Aphonopelma iodium (A. iodius), A. melanium (A. melanius), A. angusi, A. nevadanum, described from the Mojave Desert and the Great Basin are treated as a single species ;
Aphonopelma iodium (Chamberlin 1939) is proposed as the species name since it is one of two possible
senior synonyms (the other, A. melanium (A. melanius) in the same publication) and is the specific nam e
of the first Theraphosidae to be described from the Mojave Desert ; A. iodium is redescribed. Generic,
subgeneric, and specific characters previously used to separate Aphonopelma are reviewed. Aphonopelma
is redefined; Clavopelma is removed from the synonymy of Aphonopelma. The status of the following
eight species described prior to 1939 with type localities either in the United States or in Baja, Californi a
is discussed: Aphonopelma californica, A. leiogaster (Doleschall), A. steindachneri (Ausserer), A. rusticum, A. marxi, A. helluo (Simon), A. rileyi (Marx), and A. pseudoroseum (Strand). Aphonopelma steindachneri , A. rusticum, A. marxi, and A. helluo are considered as valid species ; A. californica, A. leiogaster, A. rileyi,
and A. pseudoroseum are considered as nomina dubia.
A new species of the genus Haplopelma
from Burma is described. Two other closely related species, Haplopelma minax
(Thorell) and Haplopelma albostriatum
(Simon), are redescribed.
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.
Chilobrachys huahini sp. n. from Thailand can be identified by its size and
by a spermatheca of "C.luteolus"-type. Maxillary lyra with 3 rows of paddle
setae, fourth leg shorter than first.
A monotypic theraphosid spider genus, Crassicrus
new genus, and a new species Crassicrus lamanai
new species, are described from the tropical dry forest of north-central Belize . Natural history and biogeographical notes are given.
The species up to now named Avicularia magdalenae
(Karsch 1879) is an undescribed one. Both sexes differ in their markings. In the female the spermathecae consists of two thickly and long tubes. In the male the embolus is bend apically only (similar to Avicularia bicegoi
Mello Leitao, 1923)
