Natural hosts.—Anaplecta sp., Venezuela, Caracas (Thaxter, 1905, 1908); Trinidad (Thaxter, 1931): On antennae.
Cockroach, Sumatra (Thaxter, 1931).
Herpomyces appendiculatus Thaxter
Natural host.—Platyzosteria scabra, Australia, N.S.W. (Thaxter, 1931): On antennae.
Herpomyces arietinus Thaxter
Natural hosts.—Ischnoptera sp., U.S.A., Georgia (Thaxter, 1908).
Parcoblatta uhleriana, U.S.A., Massachusetts (Roth, unpublished data, 1957): The nymphs were in a culture of Parcoblatta virginica which was infected with this fungus; it is possible that these P. uhleriana became infected by contact with P. virginica. Fungus identified by Dr. R. K. Benjamin.
Parcoblatta virginica, U.S.A., Massachusetts (Roth, unpublished data, 1957): Fungus determined by Dr. R. K. Benjamin. Fungus found on antennae, palpi, legs, body surface (pl. [27], A).
Parcoblatta sp., U.S.A., Kentucky, Massachusetts (Thaxter, 1902, 1908): On antennae.
It is likely that Thaxter's host records (certainly those assigned to Temnopteryx and possibly those assigned to Ischnoptera) were species of Parcoblatta. Hebard (1917) has shown that all the species referred to Ischnoptera in the United States, except I. deropeltiformis, now belong in the genus Parcoblatta. All species originally referred to the genus Temnopteryx in the United States are now synonymized with species of Parcoblatta.
