Figs 23–24 .

Material studied: 3 ɗɗ, 1 damaged Ψ, Vietnam, Tay Ninh Province, Logo-Xamat National Park (11 0 02’– 11 0 47’N, 105 0 57’–106 0 04’E), deciduous forest, November 2003, leg. Nguyen Duc Anh.

Previous record: Vietnam, Dong Nai Province, Cat Tien National Park ( Golovatch & Semenyuk, 2010).

Remarks: This species has recently been described from southern Vietnam ( Golovatch & Semenyuk, 2010). The new record comes from a region lying only about 150 air-km southwest of the type locality.

The line drawings of gonopod structure in the original description fail to show a very long distofemoral process (dp), which actually is present in this species. Apparently, in the single gonopod that was illustrated, this process was broken off. The SEM images are added here ( Figs 22–23 ) to correct this mistake, and to make this species more easily recognizable.

Key to Anoplodesmus species known from Vietnam (based on ď characters)

1. Gonopod without distofemoral retrorse spine. Solenophore (= postfemoral region) with only two distinct distal processes. Male sternite 5 with an evidently bifid lamina between coxae 4, and two projections between coxae 5........... ............................................................................................................................................................. A. borealis sp. n.

- Gonopod with an obvious distofemoral process. Solenomere with more than two lobes. Male sternite 5 with only a lamina between coxae 4 .............................................................................................................................................. 2

2. Solenomere with three dentiform processes distally, and another two lobes parabasally on lamina medialis............... ..................................................................................................................................................................... A. anichkini

- Solenomere with two long spines and a knife-shaped lobe distally. Lamina medialis with two spines parabasally, while lamina lateralis with two smaller spines ......................................................................... A. solenophorus sp. n.
