The penile morphologies of nocturnal prosimians are complex and vary considerably between genera and species. Accordingly, comparative morphology can be useful in taxonomic studies, particularly when assessing the status of newly discovered species. I measured features of penile morphology—surface area of the glans penis; shape and size of the keratinized spines on the glans—for populations representing 14 species within the subfamily Galagoninae. Intraspecific variations in penile morphology… 
Comparative penile morphology of East African galagos of the genus Galagoides (family Galagidae): implications for taxonomy
TLDR
The results support other recent morphological and behavioral studies that consider these five galagos to be distinct species, and are probably phylogenetically distinct.
Characterizing cryptic species: A morphometric analysis of craniodental characters in the dwarf galago genus Galagoides.
TLDR
Galagoides demidoff and G. thomasi can be distinguished relatively reliably, and are broadly sympatric across western and central Africa, and neither species showed evidence of sexual dimorphism in craniodental size or shape.
Morphological Correlates of Speciation in Bush Babies
AbstractMorphology is not a reliable specific indicator in nocturnal animals. Nevertheless, because species are genetically independent, appropriate analytic methods should reveal subtle and
Taxonomy of the Genus Perodicticus
TLDR
Previously undescribed features present in the population assigned to the genus Perodicticus have been found, including a bowed fin on the mesial margin of the lower (caniniform) anterior premolar in most of the specimens conforming to the descriptions for P. ju-ju and P. p.
Taxonomy of the Bornean Slow Loris, With New Species Nycticebus kayan (Primates, Lorisidae)
TLDR
Differing facemask patterns, particularly influenced by the amount of white on the face, significantly clustered together by geographic regions, separated by notable geographic boundaries support the recognition of four species of Bornean lorises.
A giant among dwarfs: a new species of galago (Primates: Galagidae) from Angola.
TLDR
This discovery points to the importance of Angolan forests as refuges for endemic biodiversity and there is an urgent need to establish conservation measures and designate protected areas.
Intraspecific Variation in the Vocalizations and Hand Pad Morphology of Southern Lesser Bush Babies (Galago moholi): A Comparison with G. senegalensis
TLDR
It is demonstrated that vocal and volar pad characteristics can be used as consistent measures of difference between species that look almost identical, and provide a practical means of distinguishing between cryptic species, whether in the field, in captivity, or, in the case of volar pads, of preserved specimens.
Taxonomy, Distribution, and Conservation Status of Three Species of Dwarf Galagos (Galagoides) in Eastern Africa
Abstract This paper reviews the complicated nomenclatural history for the Kenya coast galago, Galagoides cf. cocos, and examines whether ‘cocos’ is the valid species name for this recently
Remarkable ancient divergences amongst neglected lorisiform primates
TLDR
The results obtained in this study suggest that lorisiform diversity remains substantially underestimated and that previously unnoticed cryptic diversity might be present within many lineages, thus urgently requiring a comprehensive taxonomic revision of this primate group.
All Features Great and Small-the Potential Roles of the Baculum and Penile Spines in Mammals.
TLDR
It is observed that the presence of both the baculum and penile spines is correlated with residual testes size, suggesting a potential role in sexual selection for these traits.

  • A. Dixson

TLDR
Data indicate that variation in baculum length among primates is related to taxonomic and behavioral differences, and suggests that similar copulatory patterns may occur in species with elongated bacula, for which behavioral data are lacking at present.
Observations on the evolution of the genitalia and copulatory behaviour in male primates
Comparative studies of genital anatomy and sexual behaviour in male primates show that penile morphology and copulatory patterns tend to be more specialized in species which have a multimale or
Sexual Selection and the Evolution of Copulatory Behavior in Nocturnal Prosimians
TLDR
It will be argued that many of these animals have “dispersed” mating systems in which females are able to mate with a number of males during the peri-ovulatory phase of the ovarian cycle.

TLDR
Distribution patterns suggest that the silenus-sylvanus group probably dispersed earliest, the sinica group next, and the fascicularis group most recently; successively more recent dispersals probably contributed to reduction and disjunction of ranges of species groups that dispersed earlier.
Species Diversity Among Galagos with Special Reference to Mate Recognition
TLDR
It is argued that the number of species of nocturnal primates has been seriously underestimated and that similarlooking populations frequently belong to different species which have yet to be investigated.

TLDR
The available evidence indicates that both sexual selection and natural selection may have influenced the evolution of copulatory patterns, which are confined almost exclusively to arboreal primates.

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.

TLDR
An analysis of variability in body mass indicates that the coefficient of variation for body mass increases with increasing species mean mass.
