Larvae of 19 of the 21 species of the Argas subgenus Argas are already described. One of the two exceptions is A. (A.) macrostigmatus; we describe the larva of this species from wet nests of the crested cormorant, Phalacrocorax aristotelis, from Corsica, France. As in the adult and nymphal stages, this larva has an uncovered Haller's organ, a character shared in Palearctic members of this large genus only with A. (A.) polonicus, a Central European parasite of rock pigeons. Available larval samples of both species are indistinguishable. However, adult and nymphal A. (A.) macrostigmatus are unique for their exceptionally large spiracular plates. These are the only Argas (Argas) species which differ distinctly as adults and nymphs but hardly or not at all as larvae. Argas (A.) macrostigmatus was previously known only from a nest of the crested cormorant in the Black Sea. Ukrainian SSR.
argas亚属argas的21个物种中，已有19个物种的幼虫被描述。两个例外之一是A. (A.) macrostigmatus；我们从法国科西嘉岛凤头鸬鹚（Phalacrocorax aristotelis）的潮湿巢穴中描述了该物种的幼虫。与成虫和若虫阶段一样，这种幼虫有一个未被覆盖的哈勒氏器，在这个大属的古北区成员中，只有A. (A.) polonicus（一种中欧岩鸽寄生虫）具有这一特征。这两个物种现有的幼虫样本无法区分。然而，A. (A.) macrostigmatus的成虫和若虫以其异常大的气门板而独特。这是唯一一种成虫和若虫有明显差异但幼虫几乎没有差异或完全没有差异的argas (argas) 物种。A. (A.) macrostigmatus以前仅在乌克兰苏维埃社会主义共和国黑海的凤头鸬鹚巢穴中被发现。
