The most re- semblance to these generic features is exhibited by mem- bers of the G. chamaeleontinus species group. Several species such as G. granáis and G. robinsonii show hardly any resemblance to the remaining species of the genus. An isolated species was described by Smith (1925) as Gonocephaliis mjobergi based on a single female spec- imen collected by Mjöberg on Mt. Murud at an altitude of 7000 feet (2134 m). Until today this has remained the only known adult specimen of the species. Owing to its superficial resemblance and shared ecological niche G. robinsonii and G. mjobergi were tentatively grouped by Manthey & Denzer (1991). In the course of our inves- tigations into high altitude fonns of Gonocephaliis in par- ticular G. robinsonii (Boulenger, 1908) we re-examined the type specimen of G. mjobergi (Smith, 1925). Results Gonocephaliis mjobergi was described on the basis of a single female collected on Mount Murud, Sarawak. Sev- eral features of type specimen are in poor condition. We re-examined the holotype (BMNH , fornier- ly BMNH ) and discovered characteristics not mentioned in the original description. While the guiar sac is incomplete (Smith 1. c: "the tip missing") it is difficult to determine its actual size. From the original drawings it could already be concluded that it might reach further on- to the chest than in any other species of Gonocephalus ex- cept perhaps G. robinsonii. When we examined the holo- type we were surprised that despite the incompleteness it was clear that the onset of a complete the guiar sac would have reached the clavicular region. A feature clearly dis- tinguishing G. mjobergi from all other Gonocephaliis is the pos
