Species of Camponotus Mayr, 1861 show a high variation of worker caste numbers, from a monomorphic worker caste to strong polymorphism along a continuous range of worker sizes or true worker dimorphism. Camponotus singularis (Smith, 1858) is used as a model for a Camponotus species with two very distinct worker castes (minors and majors) which are chiefly defined by morphometric data. We investigated shifts in proportions of C. singularis female castes in order to identify major allometric patters useful for characterizing caste differences in this species as well as in other Camponotini. We describe the main morphological traits which are characteristic for the respective morphs. The major worker, or “soldier”, shows many characteristics which deviate from the minor worker, but also from the alate gyne. Its traits are assumingly modified for its function in nest defence. Morphometric data clearly set Bornean specimens of Camponotus singularis (described as var. rufomaculatus Donisthorpe, 1941) apart from specimens with other proveniences, suggesting that this island population is a distinct species.

工人、士兵和女性——Camponotus singleis (Smith, 1858) (Hymenoptera, Formicidae) 雌性种姓的形态特征和描述

Camponotus Mayr 的物种，1861 年显示出工人种姓数量的高度变化，从单一的工人种姓到沿着工人大小的连续范围或真正的工人二态性的强多态性。Camponotus singleis (Smith, 1858) 被用作 Camponotus 物种的模型，该物种具有两个非常不同的工人等级（未成年人和专业），主要由形态测量数据定义。我们调查了 C.singularis 女性种姓比例的变化，以确定主要的异速生长模式，可用于表征该物种以及其他 Camponotini 的种姓差异。我们描述了各个形态的主要形态特征。主要工人，或“士兵”，表现出许多不同于小工人的特征，也不同于有翼的妇人。它的特征可能会因其在巢穴防御中的功能而被修改。形态测量数据清楚地将婆罗洲的 Camponotus Singleis 标本（描述为 var. rufomaculatus Donisthorpe，1941）与其他来源的标本区别开来，表明该岛屿种群是一个独特的物种。
