“…The morphology of the reproductive organs in Gonyleptoidea has been shown to be very valuable in phylogenetic analyses (i.e., Kury & Villarreal 2015;Cruz-López & Francke 2015), and has been well explored in detail for some species (i.e., Bennett & Townsend 2013;Walker & Townsend 2014;Townsend et al 2015). In Cosmetidae, however, the genital morphology is somewhat uniform, if compared with Gonyleptidae for example.…”

The genus Eulibitia was described by Roewer including three species from Colombia and Ecuador: Eulibitia maculata Roewer, 1912, E. annulipes Roewer, 1912 and E. sexpunctata Roewer, 1914. Herein, the genus is revisited and only the type species, Eulibitia maculata Roewer, 1912 is maintained from the previous configuration. Eulibitia sexpunctata is transferred to Ambatoiella Mello- Leitão, 1943 and E. annulipes is considered as Cosmetinae incertae sedis. Acromares lateralis Goodnight & Goodnight, 1943 and Paramessa castanea (Sørensen, 1932) are here considered junior subjective synonyms of Messatana scalaris (Sørensen, 1932) and Eulibitia maculata, respectively. Brachylibitia Mello-Leitão, 1941, currently a junior synonym of Platymessa, is regarded as a synonym of Eulibitia. Platymessa Mello-Leitão, 1941, with two species, and the monotypic genera Messatana Strand, 1942 and Paramessa Mello-Leitão, 1933, are synonymized with Eulibitia Roewer, 1912, yielding the following new combinations: Eulibitia ectroxantha (for Brachylibitia ectroxantha Mello-Leitão, 1941), E. h-inscriptum (for Platymessa h-inscripta Mello-Leitão, 1941) and E. scalaris (for Libitia (Messa) scalaris Sørensen, 1932). Eulibitia is re-diagnosed and five new species are described: E. castor sp. nov., E. pollux sp. nov., E. clytemnestra sp. nov., E. leda sp. nov. and E. helena sp. nov. A key to the nine Eulibitia species is presented; the morphology of Eulibitia is compared with that of Libitia, Libitiella and Ambatoiella.

Brooks E.A., Townsend V.R., Allen E.A., Tuthill M.A. 2015. Interspecific variation in ovipositor morphology among Manaosbiid and Nomoclastid Harvestmen (Arachnida, Opiliones, Laniatores). -Acta Zoologica (Stockholm) 00: 000-000.The external anatomy of the ovipositor has generally been overlooked as a source of informative characters in systematic studies of laniatorean harvestmen. In this study, we used scanning electron microscopy to examine the ovipositors of nine species representing the families Manaosbiidae (five species) and Nomoclastidae (four species). Similar to the ovipositor morphology of many gonyleptoidean families, the distal tips of the ovipositors of these harvestmen have four external lobes, with the margins most commonly adorned with 10 large peripheral setae. In manaosbiid and nomoclastid species, these peripheral setae have undivided bases, striated shafts and undivided distal tips. There are typically three setae on each anterior lobe and two setae on each posterior lobe. The medial setae on both anterior and posterior lobes insert into sockets that are slightly more dorsal. We observed small, surface denticles, usually associated with a pore, on the external surface of the lobes. There was interspecific and intraspecific variation in the number and shape of these surface denticles. The association of pores with denticles on the ovipositor appears to be a feature common to not only both families but is also a trait that has not been observed on ovipositors in other families of laniatorean harvestmen.
