The presence of the same general structure and vestiture, an overall similarity in coloration with merely a few minor differences, a broad range of intraspecific variation with several intermediate color varieties forms, and the similar structure of the male genitalia in three Neotropical species of Brontostoma Kirkaldy, 1904 (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae) led to the hypothesis that all of them represent a single species, resulting in the following newly proposed subjective synonymies: B. basalis (Stål, 1859) = B. sanguinosum (Stål, 1872), syn. nov. = B. pallitarsis (Walker, 1873), syn. nov. The male genitalia of another nominal species, B. infensum Wygodzinsky, 1951, showed a set of differences which are judged to sufficiently support the recognition of it as a separate species. Intraspecific morphological and color variations of B. basalis are documented and discussed, and this species is recorded from French Guiana for the first time.
1904年的三个新热带区巨口猎蝽属（Brontostoma Kirkaldy）物种（半翅目：异翅亚目：猎蝽科：外刺猎蝽亚科）具有相同的总体结构和体表特征、颜色总体相似仅存在一些细微差异、种内变异范围广且有几种中间颜色变体形式，以及雄性生殖器结构相似，这些特征导致了一种假说，即它们都代表单一物种，从而产生了以下新提出的主观同物异名：基部巨口猎蝽（Brontostoma basalis (Stål, 1859)） = 血色巨口猎蝽（B. sanguinosum (Stål, 1872)），新同物异名 = 淡跗巨口猎蝽（B. pallitarsis (Walker, 1873)），新同物异名。另一个命名物种，即1951年的威氏巨口猎蝽（B. infensum Wygodzinsky）的雄性生殖器表现出一系列差异，这些差异被判定足以支持将其认定为一个独立物种。记录并讨论了基部巨口猎蝽的种内形态和颜色变异，并且该物种首次在法属圭亚那被记录。
