Three arachnid orders, Amblypygi, Uropygi, and Palpigradi share a narrow pedicel with Araneae, but the pro/ opisthosoma
connection in spiders is especially flexible, probably to promote mobility of the spinnerets.
These spiders were killed and then the entire opisthosoma
was extracted, fixed and contrasted.
The arthrodial membrane between the prosoma and the opisthosoma
of each horseshoe crab was exposed, and the hinge joint was sterilized with 70% ethanol.
oval prosoma and opisthosoma
, chitinized carapace) across all developmental stages and life forms, body shapes vary, e.g., in the ratio prosoma-opisthosoma or the ratio body-leg size.
Larvae were examined daily at 40-45X using stereoscopic microscopy and the number of dead larvae was counted 10 days post-treatment; indication of death included lack of movement, curled legs, and deflated opisthosoma
. Each spore inoculum experiment was replicated 10 times on 10 tubes of larvae (n = 100 larvae for each treatment).
with 6 pairs of lateral setae with setae f2 absent (Fig.
En este caso es posible reconocer a los juveniles de la especie por las proporciones de su caparazon junto con la coloracion caracteristica de su opisthosoma
(que son similares a las de las hembras adultas), como lo senala Edwards (2006) en la diagnosis que proporciona para esta especie: "Generally the three pair of large spots on the abdominal dorsum of both sexes will distinguish this species." (Fig.
with vivid pattern consisting of partly fused patches along heart and -more distinctly- along posterior midline, with irregular dots laterally.
This plate is characteristically displayed by elevating the opisthosoma
during often elaborate courtship and sometimes agonistic behaviours (Girard et al.
MATERIAL: Specimen NBMG 11012 consists of a part and counterpart of an articulated partial preabdomen of the opisthosoma
with irregular broken striations and a few reticulate elements mediolaterally, striations mediolaterally, fading away marginally.
