  author={Victor R. Townsend and Carlos V{\'i}quez and P VanZandt and Daniel N. Proud},
To facilitate identification of harvestmen of the family Cosmetidae in Central America, we developed dichotomous keys that distinguish the 33 known genera and the 133 described species for this region. Couplets are based upon characters found in the literature and examinations of museum specimens. Important characters include the number of tarsomeres on leg I, armature of the dorsal scutum, free tergites and legs, as well as the coloration and relative length of the body and legs. In addition… 
Unusual penis morphology among cosmetid harvestmen (Arachnida: Opiliones) from Mesoamerica
Two distinct forms of genitalia exhibited by members of the genus Erginulus are described and compared to the common genitalic morphology of other cosmetid harvestmen, and the systematic implications to be addressed in a subsequent revisionary study are discussed.
Giving attention to the oldies: redescription of Meterginus basalis (Arachnida: Opiliones: Cosmetidae) with some notes on the genitalia
This work presents a redescription of Meterginus basalis Pickard-Cambridge, 1905 (type species of the genus) including the first scanning electron microscopy (SEM) images of the male genital.
Paecilaema batman, a new species of Brazilian troglophilous harvestman that exhibits a remarkable color patches variation (Opiliones: Cosmetidae)
A new species of harvestman, Paecilaema batman, from Brazilian limestone caves of the state of Goias, is described, and a remarkable intraspecific color patch variation is discussed. Paecilaema
Reproductive morphology of three species of neotropical harvestmen (Opiliones, Laniatores, Gonyleptoidea)
This study used scanning electron microscopy to examine variation in male and female reproductive morphology among three species of harvestmen that are members of the superfamily Gonyleptoidea and indicates that there are several features associated with ovipositor morphology among laniatorean harvest men that may represent potentially informative taxonomic characters.
Two new species of Manaosbiidae (Opiliones: Laniatores) from Panama, with comments on interspecific variation in penis morphology
The most variable characters were the number and relative sizes of the setae that occur on the lateral margins of the ventral plate and the shape and armature of the apex of the stylus in the Manaosbiidae species Barrona felgenhaueri and Bugabitia akini.
Four new species of Cosmetus from Panama, with comments on the systematics of the genus (Opiliones: Cosmetidae)
It is suggested that the spine of area III, sexually dimorphic chelicerae and posterior legs, and pigmentation of dorsal scutum are good diagnosti c features at species level.
Interspecific variation in the microanatomy of cosmetid harvestmen (Arachnida, Opiliones, Laniatores)
There are several microanatomical structures associated with the ocularium, dorsal scutum, male chelicera, and pedipalp that could represent informative phylogenetic characters in future taxonomic studies of cosmetid harvestmen.
Ovipositor morphology of cosmetid harvestmen (Arachnida, Opiliones, Laniatores): A new source of informative characters
Interspecific variation in the external morphology of the ovipositor for 14 species from the family Cosmetidae is investigated, suggesting that future taxonomic studies of cosmetid harvestmen, and potentially other gonyleptoidean taxa, would benefit from the inclusion of descriptions of ovipOSitor morphology.
Redescription of Platygyndes Roewer 1943, a false Gonyleptidae, (Arachnida, Opiliones, Cosmetidae)
Internal morphological characters that are useful to revealing relationships among cosmetid genera are discussed and Platygyndes seems to be closely related to Moselabius Roewer, 1956 and Caracarana Roewe, 1956.
Unveiling the diversity of Phalangodus Gervais, 1842 (Opiliones: Cranaidae): descriptions of four new species from Colombia
SEM images of the penis of Phalangodus, including the type species of the genus, P. anacosmetus Gervais, 1842, are provided for the first time and sexual dimorphism and the morphology of stylar caps and ovipositor in Cranaidae are discussed.
