“…Non-sacculate species overwinter as eggs and reach the final instar in mid-summer or later. Significantly, those populations with the most well-developed male palps and female pregenital barriers tend to occur on mountains (e.g., Leiobunum hoffmani and L. calcar ) [54], where breeding seasons are likely to be short. There are also sacculate species in the north temperate region but most overwinter as immatures, attain adulthood in late spring and have potentially long breeding seasons (Fig.…”

“…All penes and opercula (right box) are drawn to the same scale; bar = 1 mm. The pedipalps are from male Leiobunum euserratipalpe and L.calcar [54]. Simple male pedipalps are roughly similar in shape and relative size to those of females.…”

“…3). The anterior median notch in the sclerotized sternum engages a sclerotized median septum on the genital operculum; the posterior margin of the sternum abuts the anterior margin of the levator apodeme (based on [54]). In both C and D, a barrier is formed by a sclerotized sternum wedged between anterior and posterior elements of the genital operculum.…”

Comparative Analyses of Reproductive Structures in Harvestmen (Opiliones) Reveal Multiple Transitions from Courtship to Precopulatory Antagonism

Explaining the rapid, species-specific diversification of reproductive structures and behaviors is a long-standing goal of evolutionary biology, with recent research tending to attribute reproductive phenotypes to the evolutionary mechanisms of female mate choice or intersexual conflict. Progress in understanding these and other possible mechanisms depends, in part, on reconstructing the direction, frequency and relative timing of phenotypic evolution of male and female structures in species-rich clades. Here we examine evolution of reproductive structures in the leiobunine harvestmen or “daddy long-legs” of eastern North America, a monophyletic group that includes species in which males court females using nuptial gifts and other species that are equipped for apparent precopulatory antagonism (i.e., males with long, hardened penes and females with sclerotized pregenital barriers). We used parsimony- and Bayesian likelihood-based analyses to reconstruct character evolution in categorical reproductive traits and found that losses of ancestral gift-bearing penile sacs are strongly associated with gains of female pregenital barriers. In most cases, both events occur on the same internal branch of the phylogeny. These coevolutionary changes occurred at least four times, resulting in clade-specific designs in the penis and pregenital barrier. The discovery of convergent origins and/or enhancements of apparent precopulatory antagonism among closely related species offers an unusual opportunity to investigate how major changes in reproductive morphology have occurred. We propose new hypotheses that attribute these enhancements to changes in ecology or life history that reduce the duration of breeding seasons, an association that is consistent with female choice, sexual conflict, and/or an alternative evolutionary mechanism.

This paper reviews 68 scientific names of species of Phalangiidae reported from North, Central, and South America. We found that: 1)16 species of Phalangiidae distributed across 10 genera (Leptobunus, Liopilio, Lophopilio, Mitopus, Odiellus, Oligolophus, Opilio, Paroligolophus, Phalangium, and Rilaena) are still valid; 2) up to 38% of these species have been introduced into North America from Europe and pos¬ sibly Asia; and 3) no members of this family are native to Mexico, Central and South America, or the Caribbean. An additional genus and species (i.e., Megabunus diadema) is recorded from Iceland and is to be watched for in North America. We recognize four new synonyms, one change in family status, and two other changes in status. We confirm both the statement by Levi and Levi (1955) that Opilio angulatichelis Roewer 1952 = Phalangium opilio Linnaeus 1758 and Bishop's (1949) conclusion thatLacinius ohioensis (Weed 1889a) = Odielluspictus (Wood 1868). Egaenus and Lacinius do not occur anywhere in the Americas. Range extensions (i.e., new provinces or states) are given for Liopilio glaber (1 new extension), Lophopilio palpinalis (1, introduced; new record for North America), Mitopus morio (2 new provinces), Odiellus pictus (3 new provinces; 1 new USA county), Rilaena triangularis (1, introduced), Opilioparietinus (2, possibly introduced), and Phalangium opilio (18, possibly introduced). Taxonomic changes are: lectotypes and paralectotypes are designated for Mitopus californicus Banks 1895, Odiellus pictus argentus Edgar 1966, and Oligolophus montanus Banks 1893c; Lacinius texanus Banks 1893a = Odiellus pictus (Wood 1868), new synonym; Mitopus californicus Banks 1895 = Opilio parietinus (De Geer 1778), new synonym; Mitopus dorsalis Banks 1900 = Mitopus morio Pabricius (1779), new synonym; Parodiellus projectus Goodnight and Goodnight 1942a (Phalangiidae) = Protolophus niger Goodnight and Goodnight 1942b (Protolophidae), new synonym, new family rank; Opilio chickeringi = Lanthanopilio chickeringi is placed in the "Metopilio group", new status; and Phalangium rudipalpe Gervais 1849 = Genus and species inquirenda (Sclerosomatidae: Gagrellinae), new status. Anew subgeneric name, Slimlepto, is given for the parvulus group of Leptobunus. A taxonomic key to the valid Phalangiidae of the Americas is provided.
