TL;DR: A putative new genus of the Oligacanthorhynchidae and a new species of Mediorhynchus differs from all congeners by a suite of characters, including a proboscis armature of 125–156 hooks arranged in 24–26 longitudinal rows of 24– 26 hooks and 30 rows of 5–6 spines.
Abstract: Forty-seven individuals comprising 4 species of birds, Tockus leucomelas, Crecopsis egregia, Turdus smithi, and Bubo africanus; 4 species of mammals, Otolemur crassicaudatus, Gerbilliscus leucogaster, Mus minutoides, and Mus sp.; and 1 species of reptile, Varanus albigularis, all from South Africa were examined for acanthocephalans. Centrorhynchus clitorideus, Mediorhynchus mokgalongi n. sp., Masticophis taeniatus, Moniliformis acomysi, Moniliformis sp., Plagiorhynchus (Prosthorhynchus) cylindraceus, and a putative new genus of the Oligacanthorhynchidae were found. Additional characters of C. clitorideus were described. The new species of Mediorhynchus differs from all congeners by a suite of characters, including a proboscis armature of 125–156 hooks arranged in 24–26 longitudinal rows of 24–26 hooks and 30 rows of 5–6 spines. The putative new genus has a total of 24 hooks arranged in 12 longitudinal rows of 2 hooks. All are new host and locality records.
TL;DR: The spring field trip with the herpe tology class into Kane County, east of Kanab, produced 18 specimens of this heretofore rare species, and in all three localities the snakes were found in rocky patches in the juniper-piny on pine community.
Abstract: Tantilla utahensis Blanchard. The spring field trip with the herpe tology class into Kane County, east of Kanab, produced 18 specimens of this heretofore rare species. They were found under rocks along the base of the Vermilion Cliffs 8 miles east of Kanab, at a small rocky hill 17 miles east of Kanab, and near the north end of Five Mile Valley, just two miles above Catstairs Canyon, 38 miles east of Kanab. The elevation of these localities is approximately 5000 feet, at least 2000 feet higher than previous records for this species in the State of Utah. In all three localities the snakes were found in rocky patches in the juniper-piny on pine community. Other reptiles associated with this community are as follows: Crotaphytus (collaris and wislizenii), Scelo porus {undulatus and magister), Uta {stansburiana and ornatus), Cnemi dophorus tigris, Phrynosoma platyrhinos, Hypsiglena torquata, Masticophis taeniatus, Pituophis catenifer, and Crotalus viridis. A recently ingested centipede (Scolopendra polymorpha Wood), measuring 44 mm., was regurgitated soon after one of the larger specimens (BYU 11279) was collected.
