Stick insects of Sulawesi, Peleng and the Sula Islands, Indonesia- a review including checklists of species and descriptions of new taxa (Insecta: Phasmatodea) Author Hennemann, Frank H. text Zootaxa 2021 2021-12-06 5073 1 1 189 journal article 10.11646/zootaxa.5073.1.1 1175-5326 5760636 AA3269D1-CA2F-4528-BC9D-3A4C75D05BD9 Genus Ramulus Saussure, 1862 ( Figs. 28–35 ) Type-species: Bacillus humberti Saussure, 1862: 472 [= Ramulus pseudoporus ( Westwood, 1859: 42 , pl. 4: 6)], by original monotypy. Comments: This is one of the most speciose genera of Australasian Phasmatodea and due to intraspecific variability in ♀♀ and strong sexual dimorphism obviously comprises numerous synonyms that have yet to be revealed. There-fore, the entire genus deserves a comprehensive revision at the species level. Günther (1938: 58) and Hennemann (1998: 124) have listed the species of Ramulus recorded from Sulawesi . A list of all species that have so far been recorded from Wallacea is presented below. The author is aware of at least four further potentially undescribed species from Sulawesi , but while one is only known from the ♀♀ and is not unlikely be the opposite sex of Ramulus supernumerarius (Brunner v. Wattenwyl, 1907; see comments on this species below), the other three species are only known from single rather incomplete ♂ specimens. It is hope that more material of this genus from Sulawesi becomes available to increase our knowledge of the true diversity of Ramulus on the island. Species recorded from Wallacea:
