( Fig. 109 )

Platyxantha balyi Jacoby, 1895b: 111 (original description)

Type material examined. LECTOTYPE (designated here): ♀, ‘Type / H. T. [white round label with red collar, p] // Perak [w, h] // Jacoby Coll. / 1909-28a [w, p] // Platyxantha / Balyi Jac. / Type [b, h] // LECTOTYPE / Platyxantha / balyi Jacoby, 1895 / J. Bezděk des. 2017 [r, p]’ ( BMNH). PARALECTOTYPE: ♀, ‘ Perak [w, h] // Jacoby Coll. / 1909-28a [w, p] // PARALECTOTYPE / Platyxantha / balyi Jacoby, 1895 / J. Bezděk des. 2017 [r, p]’ ( BMNH).

Comments. Platyxantha balyi is a species completely overlooked by all subsequent authors and thus missing in all catalogues and publications. It was described from Perak from an unspecified number of specimens, however, Jacoby must have had at least two specimens as he mentioned length span. In the BMNH I have found two syntypes (females) belonging to two different species. One female is certainly Hyphaenia and is designated here as a lectotype ( Fig. 109 ). The other female is a representative of Hoplosaenidea but I am unable to assign it to any species at the moment. The lectotype is similar to Hyphaenia azlani Mohamedsaid, 1998 but I avoid synonymizing them without the study of type specimens.
