The javanicus species-group, belonging to the large, widespread, Southeast Asian genus Glyphiulus Gervais, 1847, is established for those species in which the males have legs 1 provided with medially contiguous but not entirely fused coxal processes, coupled with usually 4- or 5-segmented telopodites, along with carinotaxy patterns of the collum and metaterga that are highly characteristic and often stable. This group encompasses 19 species, all keyed here, including Glyphiulus sinensis (Meng & Zhang, 1993) n. comb. (before in Podoglyphiulus Attems, 1909), and 10 new species taken from caves: G. obliteratus n. sp., G. subobliteratus n. sp., G. obliteratoides n. sp., G. parobliteratus n. sp., G. paracostulifer n. sp. and G. intermedius n. sp. from southern China; G. mediobliteratus n. sp. from North Vietnam; and G. costulifer n. sp., G. subcostulifer n. sp. and G. percostulifer n. sp. from Laos.
