Natural host.—Leurolestes pallidus, British Guiana and Trinidad (Thaxter, 1931): On antennae.
Herpomyces lobopterae Thaxter
Natural host.—Loboptera sp., Argentina (Thaxter, 1931): On antennae.
Herpomyces macropus Spegazzini
Natural host.—Blaberus sp.?, Argentina (Spegazzini, 1917).
Cockroaches, Peru, Puerto Rico, Ecuador, and Haiti (Spegazzini, 1915, 1917): Material previously assigned by Spegazzini (1915) to H. paranensis was also placed by him in this new species. However, Thaxter (1931) believed that H. macropus may be synonymous with H. paranensis, but he provisionally retained H. macropus because he had not seen Spegazzini's material.
Herpomyces nyctoborae Thaxter
Natural hosts.—Nyctibora tomentosa, U.S.A., Texas (Thaxter, 1905, 1908): On antennae. This cockroach is not established in Texas, and the specimen may have been misidentified (Gurney, personal communication, 1958).
Nyctibora sp., Argentina (Spegazzini, 1917): On antennae.
