Silhouettella loricatula (Arachnida, Araneae, Oonopidae): A Haplogyne spider with complex female genitalia
TLDR
During a copulation in the laboratory the ejection of a secretory sac that most probably contained spermatozoa was observed, indicating sperm dumping in S. loricatula.
Potential and limitations of X-Ray micro-computed tomography in arthropod neuroanatomy: A methodological and comparative survey
TLDR
This study shows that micro‐CT is highly suitable for analyzing arthropod neuroarchitecture in situ and allows specific neuropils to be distinguished within the brain to extract quantitative data such as neuropil volumes, and data acquisition is considerably faster compared with many classical histological techniques.
Extreme convergence in egg-laying strategy across insect orders
TLDR
A novel egg-deposition mode for Phasmatodea is reported performed by an undescribed Vietnamese species of the enigmatic subfamily Korinninae that produces a complex egg case (ootheca), containing numerous eggs in a highly ordered arrangement.
The male genital system of the cellar spider Pholcus phalangioides (Fuesslin, 1775) (Pholcidae, Araneae): development of spermatozoa and seminal secretion
TLDR
Spermatogenesis begins weeks before maturity and takes place continuously in the long-lived males of P. phalangioides, with special emphasis on its development and seminal secretions.
Record breaking achievements by spiders and the scientists who study them
TLDR
A list of 99 record breaking achievements by spiders, compiled in a world-record style format, to provide an entryway for teachers and students—as well as scientists themselves—into the biology of spiders (the “Spider World Records”).
A Comparative Analysis of the Morphology and Evolution of Permanent Sperm Depletion in Spiders
TLDR
It is corroborated that sperm depletion in the golden orb-web spider Nephila clavipes is permanent by uncovering its mechanistic basis using light and electron microscopy and suggested that PSD may be an energy-saving adaptation in species where males are limited to monogamy.
Effects of starvation on reproduction of the predacious mite Neoseiulus californicus (Acari: Phytoseiidae)
TLDR
Findings suggest that gravid females maintained an oocyte in the dorsal region after laying two eggs during starvation, the oocyte was not absorbed during starvation and the oocytes advanced vitellogenesis and the fusion of two nuclei, and the viteLLogenic oocytes was not enveloped with an eggshell and had not started embryogenesis.
Ultrastructure of spermatozoa of orsolobidae (Haplogynae, Araneae) with implications on the evolution of sperm transfer forms in Dysderoidea
TLDR
The synspermia of species of Tasmanoonops and Hickmanolobus were not covered by a secretion sheath suggesting a previously unknown strategy of transferring sperm that is possibly related to sperm residency time or female triggered processes after copulation.
