Abstract A new type of stridulatory organ is described and figured occurring in three species of Mallinella Strand from Thailand and Singapore. In one species there are four stridulatory organs, with the ridges on femora I and II and the pegs in the shape of granulations on femora II and III. In both the other species an additional pair occurs, with ridges on femora III and pegs on femora IV. To date no more than four stridulatory organs have been recorded on a single spider. Examples of… 

On Melchisedec, a New Genus of the Spider Family Oonopidae (Araneae, Dysderoidea)

TLDR
A new genus, Melchisedec, is established for two new Afrotropical species, M. thevenot and M. birni, which are unique among oonopids in having a crest on the ventral pedicel sclerite, and in having very short, scepterlike setae on the distal metatarsi I and II.

Two new species of Pamphobeteus Pocock 1901 (Araneae : Mygalomorphae : Theraphosidae) from Brazil, with a new type of stridulatory organ

TLDR
Two new species of Pamphobeteus Pocock 1901 are described from Brazil and a new type of stridulatory organ is described from legs III and IV of P. crassifemur sp.

Three new species and a new record of the spider genus Mallinella Strand, 1906 from Brunei (Araneae, Zodariidae).

TLDR
This article is the first formal record of the genus Mallinella Strand, 1906 in Brunei Darussalam and the females of M. bigemina Dankittipakul, Jocqué & Singtripop, 2012 are here recorded from Brunei for the first time.

The goblin spider genus Xyphinus (Araneae; Oonopidae).

The goblin spider genus Xyphinus Simon 1893 presents several peculiar characters, such as spines and spikes on carapace and abdomen in different sizes and shapes, strongly modified male palps with

Revalidation of the spider genus Citharoceps Chamberlin, 1924 (Araneae, Segestriidae)

TLDR
Citharoceps is revalidated and redescribed based on the occurrence of the stridulatory apparatus in CitharoCEps fidicina and Segestria cruzana Chamberlin & Ivie, and also on the presence of distinguishable characters, such as the length of the labium-sternum junction.

Three new species of comb-tailed spiders (Araneae: Hahniidae) from a Mexican oak forest with comments on their natural history and sexual behavior

TLDR
Three new hahniid species are described from a total of 1,131 individuals collected during spider inventories in Veracruz, Mexico, from leaf litter using active searching, sifted litter processed with Berlese funnels and pitfall traps and sexual behavior and the natural history of N. aspembira sp.

The new Southeast Asian genus Cambonilla gen. nov. (Zodariidae, Araneae): ‘bis repetita placent’

TLDR
A cladistic analysis based on morphology showed that the new genus is the sister-group of Heliconilla Dankittipakul, Jocqué & Singtripop, 2012 with which it shares the granulated carapace with branched setae and the marbled ventral abdominal pattern, but differs by the abdominal, tubular sclerotized protrusion around the pedicel in males and the absence of posterior ventrals abdominal spines in the female.

Stridulation by cosmetid harvestmen (Arachnida: Opiliones)

TLDR
Comparative morphological data supports the hypothesis that there are cosmetid harvestmen that may use surface features on the chelicerae and pedipalps to produce vibrations which may function as a secondary defense mechanism.

A new ant-eating spider genus Suffascar (Araneae : Zodariidae) endemic to Madagascar: a considerable extension of the dual femoral organ clade

TLDR
Using a morphology-based phylogenetic analysis, it appears that SF and DF constitute clearly monophyletic entities with a sister-group relation, and these groups may be considered as distinct subfamilies and, together, they may turn out to be sister to the Storeninae.

Morphology of setae on the coxae and trochanters of theraphosine spiders (Mygalomorphae: Theraphosidae)

TLDR
Mygalomorphae spiders have several cuticular structures, such as stridulating, sensory and urticating setae, which offer great potential for phylogenetic studies, which are examined using scanning electron microscopy to sample and describe the diversity of setae and code morphological characters useful for phylogenetics.

A review of the Chilean spider genus Olbus, with notes on the relationships of the Corinnidae (Arachnida, Araneae)

TLDR
A particular arrangement of enlarged cylindrical gland spigots, at least three on posterior median spinnerets, and two on posterior laterals, is proposed as a synapomorphy of Corinnidae.

Sound Production and Associated Morphology in Male Jumping Spiders of the Habronattus agilis Species Group (Araneae, Salticidae)

TLDR
Stridulating male jumping spiders in the Habronattus agilis species group have a file on the back of the cephalothorax and stout, curved setae on the front of the abdomen and stridulation may have evolved from the common salticid behavior o f abdomen twitching.

Morphological phylogeny of cobweb spiders and their relatives (Araneae, Araneoidea, Theridiidae)

TLDR
The results suggest the monophyletic origin of both kleptoparasitism and araneophagy in the lineage leading to Argyrodinae, negating hypotheses that either arose from the other.

TLDR
This chapter discusses the relationships between Theridiid Interrelationships and Familial Placement, and some examples of such relationships can be found in the work published in “Theridiid Families: Foundations of a Biochemical Family, 2nd Ed.” (2003).

GENITALIC POLYMORPHISM—A CHALLENGE FOR TAXONOMY

TLDR
It explains why genitalic polymorphism is rarely observed, and why cases of atavism with loss of behavioral adaptations through deleterious mutations or reversions and reappearance of ancestral genital characters, are expected to occur regularly.

A generic revision of the spider family Zodariidae (Araneae). Bulletin of the AMNH ; no. 201

TLDR
The Zodariidae are filter feeders of the Hetaerica stream, which in turn filters out the Hetalia of the Tournaisian stream, whose waters are filter fed by the Heterosexual stream.

Female control : sexual selection by cryptic female choice

TLDR
Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating.
