The tribe Caenoculini Sun & McCafferty, 2008 is revised, now including the genera Caenoculis Soldán, 1986, and Tigrocercus Malzacher, 2006. Improved diagnoses of these two genera are given. Caenoculis dangi Soldán, 1986 is transferred to the genus Tigrocercus and Tigrocercus nastassjae Malzacher, 2013 to the genus Caenoculis. Caenoculis acutalis Zhou, Sun & Mccafferty, 2003 is regarded as representative of a separate genus Brachoculis n. gen. A diagnosis of the new genus is given. Relationships within the Brachycercinae are discussed.

The female and the ootheca of the Philippine endemic Tagalomantis manillensis (Saussure, 1870) are described and illustrated for the first time. The male is re-described in detail. The species was so far only known from the island of Luzon, but also occurs in suitable habitats on Panay. Although locally relatively abundant, it is confined to primary and old secondary rainforests and threatened by habitat loss. The life history of Panay populations is outlined. The name Euchomenellini Giglio-Tos, 1916 is proposed for the oriental members of Angelinae (Euchomenella, Indomenella and Tagalomantis). The tribus is placed among Deroplatyinae due to morphological and genital characters. Cotigaonopsis Vyjayandi, 2009 is transferred to Rivetinini. A key to the genera of Deroplatyinae is provided.

Palearctic tachinid/host records published until 1937 are critically compiled.

The following new species from Malaysia/Borneo are described: Microbolitonaeus loebli n. sp., Thesilea bosuangi n. sp., and T. convexicollis n. sp. New combination: Zophophilus bosuangi (Grimm, 2016) n. comb. = Promethis bosuangi Grimm, 2016. The male of Ceropria speciosissima Gebien, 1914 is described. Platydema becvari Schawaller, 2004 is recorded for the first time from Borneo. New faunistic data of five further species are added.

Ceropria adelpha n. sp. from West Malaysia and C. foveata n. sp. from Sumatra are described, illustrated, and compared with the similar species C. speciosissima Gebien, 1914. The male of C. adelpha is distinguished by different shape of elytral mucro and aedeagus, different structure of last abdominal ventrite, and densely punctured elytral striae. The female is unknown. C. foveata is known only from the female, but the species is readily identifiable by foveate outer punctural rows of elytra.

Twelve species of Bornean Cryptocephalini are described as new for science: Coenobius matangi n. sp., C. sabahensis n. sp., C. sarawacensis n. sp., C. schawalleri n. sp., Cryptocephalus borneoensis n. sp., Cr. geiseri n. sp., Cr. klimenkoi n. sp., Cr. nigrofulvus n. sp., Cr. nitidicornis n. sp., Cr. sepilocus n. sp., Cr. subcostipennis n. sp., and Cr. subserricornis n. sp. The genus Bucharis Baly, 1865 is recorded from Borneo for the first time. Cryptocephalus moultoni Bryant, 1954 is transferred to the genus Melixanthus Suffrian, 1854. New replacement names are proposed: Coenobius weiseanus nom. nov. for C. basalis Weise, 1913, and C. pici nom. nov. for C. bicolor Pic, 1943. Keys for all species of Bornean Cryptocephalini are given.
