Diagnosis. The male of this new species is very similar to that of Parasteatoda asiatica ( Bösenberg & Strand, 1906) in the structure of the male palp, but can be distinguished by the following: 1) conductor terminal needle-shaped, without teeth in prolateral view ( Figures 1D View Figure 1 and 2C), while finger-shaped, with teeth in P. asiatica ( Zhu, 1998, fig. 56E); 2) anterior margin of tibiae as wide as the genital bulb in ventral view ( Figures 1B View Figure 1 and 2B), while about 3/4 width of the genital bulb in P. asiatica ( Zhu, 1998, fig. 56D). The female is similar to P. quadrimaculata ( Yoshida et al., 2000) , but can be distinguished by the following: 1) atrium opening upward in ventral view ( Figures 3B View Figure 3 and 4A), while atrium opening downward in P. quadrimaculata ( Yoshida et al., 2000, fig. 34); 2) fertilization ducts originate from the center of inner margin of spermathecae in ventral view ( Figures 3B View Figure 3 and 4A), while from the base of inner margin of spermathecae in P. quadrimaculata ( Yoshida et al., 2000, fig. 34); 3) visible portion of copulatory ducts extend downward to epigastric furrow in dorsal view ( Figures 3C View Figure 3 and 4B), while they extend upward to median inner margin of spermathecae in P. quadrimaculata ( Yoshida et al., 2000, fig. 35); 4) the spermathecae oval in new species ( Figure 3A View Figure 3 ), while globular in P. asiatica ( Figure 3A View Figure 3 ; Yoshida et al., 2000, figs. 32 and 33).
Etymology. The specific name is a combination of the prefix “ aequipei- ” (dual-band) and “ formis ” (form), referring to the abdomen with 2 transverse bands, adjective.
