Penises of two species of opisthobranch mollusks of Philine were first examined with use of a scanning electron microscope: Ph. aperta (Linnaeus, 1767) and P. finmarchica M. Sars, 1858. This study revealed significant morphological differences. The morphology of male copulatory apparatus of these species is discussed

Two deep-sea polyclad species are described. Both species were found in association with wood-boring bivalves on oak and fir wood blocks that had been deployed on heavy sediment in the Cascadia Basin and Escanaba Trough in the North Pacific Ocean. Anocellidus profundus n. gen. n. sp. warrants erection of Anocellidae, n. fam. because of the unique position and orientation of the male copulatory apparatus. A. profundus lacks eyes but has long, nuchal tentacles and a ventral, arrowhead-shaped organ of putative sensory function. The male copulatory apparatus is located posterior to the male gonopore and is directed anteriorly. Highly muscularized spermiducal bulbs are present, a prostatic vesicle is lacking. A large Lang’s vesicle characterizes the female reproductive system. Oligocladus voightae n. sp. is defined by the presence of a mouth located anterior to the brain. Few and minute tentacular eyes are present. The seminal vesicle is connected to an auxiliary sperm storage vesicle, and a posterior anal pore is present in the main median branch of the intestine. All type material is deposited at the Field Museum of Natural History, Chicago, Illinois, USA.

AbstractDrawings are reproduced of the male copulatory apparatus in a number of Macaronesian Aphanarthrum. Lectotypes are designated for the Wollaston species of the genus. The following new taxa are described: A. wollastoni n.sp., A. glabrum nudum n.ssp., A. subglabrum n.sp., A. canescens polyspiniger n.ssp., and A. canariense longipes n.ssp.

Salminus Brasiliensis

AbstractA new species of Kritskyia Kohn, 1990 (Monogenea, Dactylogyridae, Ancyrocephalinae) is described from the urinary bladder of Salminus brasiliensis (Cuvier, 1816) (Characiformes, Characidae) from the Cuiabá River, the Pantanal wetlands, Brazil. The male copulatory apparatus of the new species differs from those of other species of the genus by the presence of a bipartite accessory piece (distally and proximally linked), one part grooved, serving as guide for distal portion of the MCO. Moreover, the vagina of the new species differs from those of congeners by possessing distal digitiform processes.

A New Species

Cryptocellus luisedieri sp. nov. is described from a male specimen obtained from leaf litter in the Kofán Territory, southwestern Colombia. The new species exhibits a series of interesting morphological features including the presence of cuticular pits and a unique shape of the male copulatory apparatus. The new species, which is the first ricinuleid found in the southern Colombian Andes, brings to seven the number of species of Cryptocellus Westwood, 1874 known to occur in Colombia and to 66 the number of extant species of this rare arachnid order. A male-based key to the identification of the Colombian ricinuleid species and a map showing their known distribution are included.
