Abstract We document the first case of a color dimorphism in a pholcid spider. Males, females and juveniles of Buitinga safura Huber 2003 either have large black spots on the abdomen or no spots, with no intermediates. At the same time, this species shows sexual dimorphism (brown prosomal marks present in males only) and continuous prosomal pattern variation in males, females and juveniles. The abdominal pigment is located in the hypodermis. 
The Inheritance of Intrasexual Dimorphism in Female Diving Beetles (Coleoptera: Dytiscidae)
TLDR
It is suggested that the female dimorphism is determined by genetics, and that the grooved morph was dominant over the smooth one, independent of environmental factors.
EVIDENCE FOR DIRECTIONAL SELECTION ON MALE ABDOMEN SIZE IN MECOLAESTHUS LONGISSIMUS SIMON (ARANEAE, PHOLCIDAE)
TLDR
Across pholcids, males consistently have longer tibiae 1 (and probably legs in general) than females than females, and behavioral data are missing and sexual selection by female choice or inter-male display might be involved.

Beyond size: sexual dimorphisms in pholcid spiders
Abstract The extreme sexual size dimorphism of some spiders has long attracted the attention of biologists and triggered countless prominent studies on the phenomenon. This, in turn, has resulted in
Coloration in relation to ecology in the Asian spiny-backed spider, Thelacantha brevispina (Araneae, Araneidae) on Moorea, French Polynesia
TLDR
The split-brood design showed that a genetic origin of coloration is likely with strong maternal effects and distinct color differences among sites, and the reciprocal transplant confirmed the lack of a plastic response to rearing habitats.

TLDR
Results from experiments designed to assess the relative importance of genetic and environmental factors as determinants of male horn morphology support recent theories on sexual selection which predict that male ornaments will evolve to be reliable indicators of male quality.
MALE DIMORPHISMS IN BEETLES AND EARWIGS AND THE QUESTION OF DEVELOPMENTAL CONSTRAINTS
TLDR
Analysis of 17 species from six families indicates that male dimorphisms in weapon design may be common, at least in homed beetles, and constitutes evidence against the idea that the forms of these animals' weapons are the result of developmental constraints.
High species diversity in one of the dominant groups of spiders in East African montane forests (Araneae: Pholcidae: Buitinga n. gen., Spermophora Hentz)
TLDR
It is argued that current estimates of species numbers may be inaccurate and that pholcids may turn out to be one of the most diverse spider families.
Evolution and ecology of spider coloration.
TLDR
It is argued that the production of color is metabolically costly and is principally maintained by the action of sight-hunting predators, and must be distinguished from true genetic variation for color to be used as an evolutionary tool.
Inventorying and Estimating Subcanopy Spider Diversity Using Semiquantitative Sampling Methods in an Afromontane Forest
TLDR
Investigating the effect of plot-based and unrestricted (plot-less) sampling on an inventory of a megadiverse taxon, spiders, in an Afrotropical forest for the purpose of species richness estimates found collector experience did affect the number of species collected per hour and thereby overall species composition of the sample but was less important than sampling methods used and time of day.
DON'T FORGET THE BIOLOGY: A REPLY TO GREEN
TLDR
The major conclusions of this paper are unaffected by the reanalysis proposed by Green (1999), even if it were more appropriate than theirs, which the authors doubt (see below).

TLDR
The morphological details of coupling between males and females in several species clearly indicated that selection favoring mechanical fit is not responsible for these trends.

TLDR
This paper is primarily a compendium of examples of a particular developmental constraint in Cerion, designed to illustrate the importance of this constraint by the fundamental criterion of relative frequency.
Phenotypic Plasticity and the Origins of Diversity
Phenotypic plasticity is the ability of a single genotype to produce more than one alternative form of morphology, physiological state, and/or behavior in response to environmental conditions.
