Introduction
. According to Rule 10a, the name of a genus is a substantive, or an adjective used as a substantive, in the singular number and written with an initial capital letter. The name may be taken from any source and may even be composed in an arbitrary manner. It is treated as a Latin substantive.
. Rule 65 of the Bacteriological Code (1990 Revision) states (i) that a Latin or Greek word adopted as a generic name retains the classical gender of its language of origin; (ii) that generic names which are modern compounds from two or more Latin or Greek words take the gender of the last component of the coumpound word; and (iii) that arbitrarily formed generic names or vernacular names used as generic names take the gender assigned to them by their authors.
. An adjective used as a substantive may be in the masculine, in the feminine or in the neuter gender. For example, Rhodoferax is in the masculine gender, Propioniferax is in the feminine gender and Haloferax is in the neuter gender.
A specific epithet or a subspecific epithet, treated as an adjective, must agree in gender with the generic name [Rules 12c and 13b]. For the correct formation of specific and subspecific epithets treated as adjectives, it is therefore necessary to know the gender of the genus name or of its last component.
See the file Latin and neo-Latin adjectives or participial adjectives used as specific or subspecific epithets (J.P. Euzéby & B.J. Tindall).

Last components in compound generic names of masculine or feminine gender
. The Latin noun incola (an inhabitant) may be either masculine or feminine. So generic names which end in -incola or -cola (abbreviation of incola) may be in the masculine or in the feminine gender.
For example, Aestuariicola, Alkalilimnicola, Biostraticola, Gallicola, Haloincola, Hwanghaeicola, Marmoricola, Mycetocola, Nitrincola, Pelagicola, Subtercola... are in the masculine gender; Algicola, Echinicola, Glaciecola, Halostagnicola, Litoricola, Marisediminicola, Thermincola ... are in the feminine gender.
. Many other Latin nouns may be either masculine or feminine: advena, alienigena, bos, canis, conviva, dies, exsul (or exul), haeres (or heres), imbrex, lynx, multicolor, myrtus, nasica, parens, rurigena, serpentigena, silvicola, specus, terrigena, umbraticola, unigena, ventricola, verna... However, none of these nouns has been used as the last component of a generic name (-terrigena in Haloterrigena is a feminine adjective).
Last components in compound generic names of masculine or feminine or neuter gender
. The L. part. adj. labens (gliding) used as a substantive may be in the masculine, the feminine or the neuter gender. The part. adj. labens is used in the genus name Nonlabens Lau et al. 2005. The gender is not given by Lau et al. 2005 and the specific epithet of the sole species does not allow the correct gender to be determined.

Some possible errors
1) Generic names assigned to the masculine gender:
. Methanopyrus is in the masculine gender. However, the Greek noun pur (a fire) is in the neuter gender.
. The generic names which end in -teichus are in the masculine gender. However, the Greek noun teichos (a wall of a city) is in the neuter gender. The Greek masculine noun meaning a wall (of a house) is toichos.
2) Generic names assigned to the feminine gender:
. Actinocorallia is in the feminine gender. However, the Greek noun korallion (coral) or the Latin noun corallium (coral) are in the neuter gender.
. Bactoderma is in the feminine gender. However, the Greek noun derma (skin) is in the neuter gender.
. Faenia: According to Kurup and Agre, the genus name Faenia is a Latin feminine plural name (sic)! However, according to Rule 10a, the name of a genus must be a substantive, or an adjective used as a substantive, in the singular number. Moreover, the Latin noun faenum is in the neuter gender and the plural nominative must be faena (without i).
. Spirilliplanes is in the feminine gender. However, the Greek noun planês (a wanderer, vagabond) is in the masculine gender.
. Tropheryma is in the feminine gender. However, the Greek noun eruma (a fence, barrier, guard) is in the neuter gender.
. The generic names which end in -oscilla are in the feminine gender. However, the Latin noun oscillum (a swing) is in the neuter gender.
. Sporichthya is in the feminine gender. However, the Greek noun ichthus (a fish) is in the masculine gender.
3) Generic names assigned to the neuter gender:
. Ancalochloris is in the neuter gender. However, the N.L. subtantive chloris (from Gr. adj. chloros, green) should be in the masculine or in the feminine gender.
. The generic names which end in -bium are in the neuter gender. However, the Greek noun bios (life) is in the masculine gender.
The generic names which end in -microbium, may be considered to be correctly assigned to the neuter gender (N.L. neut. n. microbium, microbe).
. Thermocladium is in the neuter gender. However, the Greek noun klados (a branch, shoot of a tree) is in the masculine gender.
. Streptoverticillium is in the neuter gender. However, the Latin noun verticillus (whorl, whirl of a spindle) is in the masculine gender.
