Diagnosis. Body similar to that of Kerinciola in external morphology, including simple structure of male anal plate; however, male genitalia clearly different: epiphallus with wide posterolateral lobes having almost angular apices and small hook-like lateral spine near each of them (vs. these lobes distinctly narrower, apically truncate and with straighter and thicker lateral processes; compare Figs. 2: I, M and 2: O); rachis strongly asymmetrical and curved downwards, with a pair of rather high lamellar keels on its posterodorsal surface (these keels probably homologous to dorsal rachial parts in Kerinciola and the majority of other Pteroplistinae genera but in one species of Malaysiola gen. nov., judging by the picture of its genitalia, rachis possibly symmetrical and somewhat different in structure; Chopard 1969: Fig. 151) (in Kerinciola , rachis symmetrical, more or less straight and with a pair of long spines homologous to dorsal rachial parts and running along ventral rachial part almost in contact with this part and with each other; compare Figs. 2: I–K and 2: O–Q); rachial sclerites in new genus and in Kerinciola fused with endoparameres which are also fused with first anterior arcuate plates (left endoparamere and left of these plates clearly isolated from right ones in both genera), but second anterior arcuate plates in Malaysiola gen. nov. probably fused with formula (in Kerinciola , they possibly isolated from formula and partly fused with previous arcuate plates; compare Figs. 2: I, J and 2: O, P).

Included species. Type species and Pteroplistes similis Chopard, 1969 (both from Malay Peninsula). The latter species was previously transferred to Kerinciola ( Gorochov 2004).

Comparison. The new genus differs from Kerinciola in the characters named above. From Pteroplistes s. l., it differs in a simple male anal plate, much wider posterolateral epiphallic lobes, and a strongly curved rachis having a pair of lamellar keels instead of dorsal processes or a process. From Tramlapiola and Crockeriola , it is distinguished by the simpler shape of the epiphallus, a strongly curved rachis and a normal structure of the first anterior arcuate plates fused with the endoparameres; from Singapuriola and Asymmetriola — by the same characters (except epiphallic ones) or by all sclerites (except rachis) symmetrical and less fused with each other, respectively; and from all other Pteroplistinae genera — by the absence of ectoparameres.

Etymology. The new genus is named after the country Malaysia and the generic name Kerinciola is due to its geographic distribution and morphological similarity to the genus Kerinciola .
