In an effort to understand the limits of leech (Hirudinea) fauna distribution in western North America, a geographical study defined by hydrological basins was undertaken and is still in progress. The report herein describes a taxonomic problem with Haemopis marmorata (Say 1824) in western North America, a species known to be difficult to distinguish by external characteristics from H. grandis (Verrill 1874) (Sawyer 1972) and H. lateromaculata. Four populations of Haemopis were found without teeth and these populations were initially identified as H. grandis (Hovingh 1993). Examination by dissection revealed that the penis sheaths of these populations were H. marmorata and that these specimens had jaws. As a result of this identification problem, the penis sheaths of all mature Haemopis were examined.In examining the reproductive organs of Haemopis, it became apparent that H. lateromaculata specimens in museum collections had often been misidentified as H. marmorata. A study of Utah (Beck 1954) and Al askan (Moore and Meyer 1951) Haemopis vouchers deposited in the United States National Museum (USNM) contained several lots identified as H. lateromaculata. Three lots of specimens that were collected from British Columbia and Newfoundland, two of which were identified by J. Madill as H. lateromaculata plus one unidentified due to poor conditions are deposited in The Canadian Museum of Nature (CMN) in Ottawa, Ontario, Canada. The two lots at CMN are the first observations of H. lateromaculata outside of the type localities of Minnesota and Iowa (Mathers 1963). A specimen from Michigan was utilized in a leech phylogenetic studies (Borda and Siddall 2004).The reproductive organs of Haemopis marmorata and H. lateromaculata specimens collected from western North America examined are presented in this paper. Based on accurate diagnosis of the species, the external characteristics (pigmentation patterns) were determined to distinguish these two species from one another. The results herein describe the geographical distribution of H. lateromaculata, and support some taxonomic and paleogeographic hypotheses concerning the family Haemopidae. MethodsSpecimens of Haemopis were collected during the last 20 years from localities in western North America. The surveys consisted of visual encounters and hand picking from the underside of stones, logs, and aquatic vegetation. The specimens were relaxed with 10% ethanol, blotted by paper towel to removed the mucous excreted from the relaxation process, fixed with 10% formalin in phosphate buffered saline between two sheets of paper towels overnight, and placed in 70% ethanol for preservation.Identification of all large Haemopis specimens was determined by examining the reproductive organs through a mid-dorsal cut from the annulus with the female gonopore posteriorly approximately 20 annuli. If the penis sheath was not located with this examination, the dorsal cut was extended anteriorly for some 10 annuli. Teeth and jaws were examined by a midventral cut of the lower lip. Posterior...

Morphological and ultrastructural features of the salivary glands and proboscises of Placobdella ornata, Placobdella parasitica, and Desserobdella picta were studied by light and electron microscopy. Chemical composition of the salivary cells was investigated using a variety of histochemical techniques. Placobdella ornata and P. parasitica have compact salivary glands with discrete pairs of anterior and posterior glands, while the salivary cells contain one mucous and three proteinaceous secretions. Salivary glands of D. picta are diffusely arranged and contain two mucous and two proteinaceous secretions. A cobalt-lysine forward-filling technique revealed that individual salivary cells consist of a roughly spherical soma and an elongated ductule. The majority of the internal space in a salivary soma is densely packed with spherical secretory granules which displace the cytoplasm to the periphery of the cell. Bundles of individual ductules enter the base of the proboscis on opposite sides and extend anteriorly. The ductules, also packed with secretory granules, are surrounded by microtubules associated with agranular endoplasmic reticulum, and merge with deep invaginations of the proboscis cuticle. The secretory granules are released at the end of these invaginations or pores. Pores were found on the tip, along the body, and on the luminal wall of the proboscises in all three species.
