New And Emended Descriptions Of Gregarines From Flour Beetles (Tribolium Spp. And Palorus Subdepressus: Coleoptera, Tenebrionidae), John J. Janovy Jr., Jillian Tikka Detwiler, Samana Schwank, Matthew G. Bolek, Alaine Knipes, Gabriel J. Langford

The following new gregarine taxa are described from larvae of flour beetles (Coleoptera: Tenebrionidae): Awrygregarina billmani, n. gen., n. sp., from Tribolium brevicornis; Gregarina cloptoni, n. sp., from Tribolium freemani; Gregarina confusa, n. sp., from Tribolilum confusum; and Gregarina palori, n. sp., from Palorus subdepressus. In addition, the description of Gregarina minuta Ishii, 1914, from Tribolium castaneum, is emended. Scanning electron micrograph studies of these species’ oocysts reveal differences in surface architecture. The Gregarina species have oocysts with longitudinal ridges, visible with SEM, whereas Awrygregarina billmani oocysts have fine circumferential striations; …

Evolutionary Avenues For, And Constraints On, The Transmission Of Frog Lung Flukes (Haematoloechus Spp.) In Dragonfly Second Intermediate Hosts, Matthew G. Bolek, John J. Janovy Jr.

Metacercariae survival patterns and their distribution in second intermediate odonate hosts were examined for four species of frog lung flukes. Surveys of aquatic larvae and recently emerged teneral dragonflies and damselflies indicated that prevalence and mean abundance of Haematoloechus spp. metacercariae were significantly lower in teneral dragonflies than larval dragonflies, while there was no significant difference in prevalence or mean abundance of Haematoloechus spp. metacercariae among larval and teneral damselflies. Experimental infections of dragonflies indicated that metacercariae of Haematoloechus coloradensis and Haematoloechus complexus were located in the head, thorax, and branchial basket of dragonflies, whereas metacercariae of Haematoloechus longiplexus and …
