Parachorius javanus (Boucomont, 1914) View in CoL

Cassolus javanus Boucomont, 1914: 251 View in CoL (type locality: Sokabumi [West Java]); Balthasar 1963: 263

Parachorius javanus: Tarasov 2017: 128 View in CoL

Parachorius singgalangensis Ochi, Kon & Hartini, 2017: 68 View in CoL (type locality: Mt Singgalang , West Sumatra), new synonymy

The original description treats P. singgalangensis View in CoL to be the closest relative of P. javanus View in CoL . The authors of the original description did not examine the types of P. javanus View in CoL and misidentified it, which caused them to conclude that P. singgalangensis View in CoL is a new species. The shape of parameres (which are medially narrowed and apically acute), of what the authors consider to be the aedeagus of P. javanus View in CoL (Figs. 10–12 in Ochi et al. 2017a), clearly indicates that their “ P. javanus View in CoL ” represents another but closely related species P. pseudojavanus Tarasov, 2017 View in CoL . At the same time the aedeagus illustrations of P. singgalangensis View in CoL (Figs. 7–8 in Ochi et al. 2017a), where parameres are notched basally and claw shaped in lateral view, belong to the true P. javanus View in CoL (see Fig. 14A, E in Tarasov 2017). Besides the shape of aedeagus P. javanus View in CoL differs from P. pseudojavanus View in CoL by the first tooth of protibia notably modified in males and approximately twice as wide as the second tooth. This diagnostic character is also mentioned and illustrated for P. singgalangensis View in CoL (Fig. 3 in Ochi et al. 2017a). Thus, based on these evidence, I can confidently conclude that P. singgalangensis View in CoL is a junior synonym of P. javanus View in CoL .

Parachorius javanus has been only known by one male holotype from West Java, the study of Ochi et al. (2017a) provides a new distribution record of this species, based on three specimens, for West Sumatra (Mt. Singgalang).
