The only previously known Mesozoic fossils of the chilopod order Geophilomorpha are two species from the Late Jurassic and Late Cretaceous, both known from single specimens that cannot be assigned with precision to a family. Four specimens from the Late Cretaceous (earliest Cenomanian) amber of Burma include three that can be identified as conspecific, described here as Kachinophilus pereirai gen. nov. sp. nov. These specimens preserve greater morphological detail in comparison with other fossil geophilomorphs: the form and fine features of the head, the maxillary complex, the trunk sternites with associated glandular pores and the ultimate pair of legs defend the assignment of the species to the extant family Geophilidae, and most probably to a derived subgroup including well-known extant genera such as Ribautia Brölemann, 1909. Confocal laser scanning microscopy supplements examination under incident and transmitted light to document details of high taxonomic relevance in the head and the forcipular segment. The modern appearance of this species and its membership among deeply nested extant clades are consistent with molecular estimates that most of the diversity of crown-group Geophilomorpha originated before the Late Cretaceous.

Geophilus gigas was described briefly by Attems in 1951 from two sites in Iran, but neither reported nor cited subsequently. The original description is inadequate to understand the full morphology and the taxonomic position of the species. Thus it is here redescribed and figured in detail based on the examination of a syntype and newly collected specimens. Furthermore it is compared with the most similar species of the genus Geophilus. G.  gigas can be reliably distinguished from other related species for the maximum body size (more than 6 cm), the arrangement and extent of the sternal pore-fields (with additional groups of pores), the coxal pores number and distribution (tens, scattered), and the size of the ulti-mate legs (swollen in both sexes).
