Unusual penis morphology among cosmetid harvestmen (Arachnida: Opiliones) from Mesoamerica

  title={Unusual penis morphology among cosmetid harvestmen (Arachnida: Opiliones) from Mesoamerica},
  author={Daniel N. Proud and Victor R. Townsend},
The harvestmen family Cosmetidae contains more than 700 described species distributed from Argentina to the USA. The monophyly of the family remains undisputed; however, the majority of cosmetid genera are poorly defined and have not been revised using modern systematic approaches. This can be partially attributed to the paucity of information regarding genitalic morphology for most cosmetid species. A better understanding of the diversity of genitalic forms in this family will facilitate more… Expand

Morphology of the male reproductive tract of the harvestman Mischonyx cuspidatus (Roewer, 1913) (Gonyleptidae: Opiliones: Chelicerata)
Abstract. Arachnida evolved different reproductive strategies in the terrestrial habitats. Knowledge of the morphology of reproductive systems varies depending on the group, and for Opiliones only aExpand


Key to the Species of Cosmetidae (Arachnida, Opiliones) of Central America, with Notes on Penis Morphology and Sexual Dimorphisms
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 thisExpand
Description of a new species of Eucynorta (Opiliones, Cosmetidae) from Cortés, Honduras.
A new species, Eucynorta rooneyi sp. nov. (Opiliones, Cosmetidae), is described from Parque Nacional Cusuco, Cortés, Honduras, a tropical montane cloud forest habitat. This is the thirty-fifthExpand
Revision of the genus Ferkeria Roewer, 1947, with the description of a new species (Opiliones: Laniatores: Cosmetidae).
A new diagnosis for the cosmetid genus Ferkeria Roewer, 1947 is proposed and a new species, Ferkaria flavicoxae sp. Expand
A fresh look over the genital morphology of Triaenonychoides (Opiliones: Laniatores: Triaenonychidae) unravelling for the first time the functional morphology of male genitalia
This study improves upon the original genitalia descriptions for two Chilean Triaenonychidae species and provides corrections to several original mistakes and misinterpretation, and describes for the first time the mechanical eversion of the penis' glans. Expand
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. Expand
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.

Taxonomic revision and cladistic analysis of the genus Metalibitia Roewer, 1912 (Opiliones, Cosmetidae, Cosmetinae)
The genus Metalibitia Roewer, 1912, is revised for the first time, and a cladistic analysis revealed that it is a monophyletic clade. This cosmetid harvestmen genus is restricted to open forests andExpand
A Review of Roquettea, with Description of Three New Brazilian Species and Notes on Gryne (Opiliones, Cosmetidae, Discosomaticinae)
The genua Roquettea Mello-Leitão, hitherto monotypic and known from Brazilian state of Pará, is rediagnosed, the type species, Roquettea singularis is redescribed, including a report on two maleExpand
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.

Genital morphology of the species is described for the first time and an effort has been made to detect diagnostic characters for the genus Cynorta, which was used in many different senses in the past and includes a large number of unrelated Neotropic species. Expand
