This species was originally described from Malabar, southern India. Subsequently, it has recorded from China (Dang et al., 2020), Malaysia, Sarawak, Timor Leste, Hong Kong and Australia (Mound & Tree, 2019). In addition, it is newly recorded here from Singapore, Indonesia (Java, Bali, Flores and Sulawesi), Thailand, Vietnam, the Philippines and Taiwan, based on a long series of specimens. In consequence, this species is widely distributed from India to Taiwan, but the distribution does not extend to the Ryukyu Islands, southern Japan, so far.
More than 500 specimens have been studied, and these show somewhat conjoined intraspecific variation in color and structure between local populations as well as even within the same population. The tibiae are variable in color, largely yellowish to largely brownish. The lateral pair of setae on the mesonotum are variable in form and length, short and acute to long and expanded. The postero-lateral setae S2 on abdominal tergite VI are usually expanded, but sometimes pointed. Large males usually have an inner small spherical tubercle at the extreme base of enlarged fore femur (Fig. 256), but large males from Vietnam and Peninsular Malaysia do not have this tubercle. Moreover, the male pseudovirgae are different in shape between local populations. At this time, it is difficult to know whether or not these local populations contain additional distinct species. However, the position of the median pair of setae on the metanotum and the length of the posteromarginal setae S1 and S2, as well as the intermediate setae between them, on abdominal tergite IX are rather stable. The distance between each of the metanotal median setae is less than the distance between these setae and the metanotum anterior margin, although these setae are much wider apart in most other species at least in Asia. The S 1 setae on tergite IX are usually much shorter than the tube, and the intermediate setae are usually much longer than half of S1. Finally, three females and four males collected from Queensland, Australia, listed below have antennal segment III with two (1+1) sense cones instead of three (1+2). However, most of other structures are indistinguishable from pictipes.
Diagnosis. Distended body length: female 1.4–1.6mm, males 1.0–1.4. Body largely brown (Figs 236 & 237); antennae brown, segment III somewhat paler, with base yellowish, segment IV often with base paler. Head (Figs 246–248) 1.1–1.2 times as long as wide, weakly sculptured with transverse reticles or striae; postocular setae expanded. Antennal segment VIII rather slender (Figs 252–254), weakly constricted basally, narrowly joined to VII; segments III and IV usually with three (1+2) and four (2+2 +1) sense cones respectively. Maxillary stylets usually not reaching postocular setae, often scarcely reaching them, wider apart, almost V-shaped. Five pairs of prothoracic setae well-developed, expanded. Mesopresternum complete (Fig. 249). Mesonotal lateral setae variable, short and acute to long and expanded. Metanotal median pair of setae rather close together and rather far from anterior margin (Fig. 250). Fore tarsus with a tooth. Tergites III–VI S2 setae: III–VI usually expanded, but those on VI often pointed. Tergite IX S1 setae much shorter than tube; intermediate setae much longer than half of S1. Tube about 0.6 times as long as head in female; terminal setae 1.5–1.6 times as long as tube. Large male: fore femur with an inner rounded tubercle at extreme base (Fig. 256).
