Morphological evidence for resolving relationships among arachnid orders was surveyed
and assembled in a matrix comprising 59 euchelicerate genera (41 extant, 18 fossil) and …

The harvestmen subfamily Hernandariinae is reviewed and a new classification is proposed
based on cladistic analysis using 67 morphological characters. The subfamily is composed …

Goniosomatine harvestmen have strongly armed pedipalps, generally large bodies and,

The large Neotropical family G onyleptidae comprises nearly 820 species divided into 16
subfamilies. The majority of publications on harvestman ecology, behaviour and scent gland …

Most chelicerates operate the world with two kinds of visual organs, the median and lateral
eyes of the arthropod ground plan. In harvestmen (Opiliones), however, members of the …

Abstract Two alkylated 1, 4-benzoquinones were identified from the defensive secretion
produced by the neotropical harvestman Goniosoma longipes (Gonyleptidae). They were …

The lines of defense in the harvestman Hoplobunus mexicanus are reported including the
complete chemical characterization of defensive secretion, a morphological description of …

The arachnids of the order Opiliones (harvestmen) produce substances used in defense. In
