A fossil genus Myanmaro gen. nov., with a species M. primus sp. nov. (Diptera, Chironomidae) is described from mid-Cretaceous Burmese amber (~100 Ma). The adult male of the new species shows the wing venation pattern lacking a cross-vein MCu, the fore leg ratio lower than 1, and the gonostylus folded inwards - features typical of the subfamily  Orthocladiinae. A bifid gonostylus, with an articulate, likely movable inner branch, is the character indicating a close relationship between Myanmaro and Diplocladius Kieffer, 1908, the latter genus previously postulated as an early lineage in Orthocladiinae. Several characters, i.e. the structure of tergite IX and the anal point, are defined as generic autapom orphies for Myanmaro. A combination of the shape of hypopygial volsellae (or their absence) and the lack of tibial combs also separate this genus from related extant Orthocladiinae and from the only known Cretaceous extinct orthoclad genus Lebanorthocladius Veltz, Azar et Nel, 2007.

A new fossil genus and species of Keroplatidae (Diptera, Bibionomorpha, Sciaroidea), Adamacrocera adami gen. et sp. nov., from the Upper Cretaceous Burmese amber is described and illustrated. Based on morphological evidence, it is placed in a new subfamily Adamacrocerinae subfam. nov. The new genus, as well as the subfamily, possesses the wing venation characteristic of the genera of some Sciaroidea incertae sedis, as well as that of the fossil families Archizelmiridae, Antefungivoridae and Mesosciophilidae, in combination with macrocerine-like habitus and male terminalia.

Fossil Genus

Three new fossil species from Burmese amber are described, one clearly in family Calamoceratidae, the other two in the highly variable family Odontoceridae. The family Odontoceridae contains 18 disparate genera, but there are no good diagnostic characters, which makes it difficult to place fossil taxa in this family. We here offer a revised diagnosis for the family, highlighting the lack of good diagnostic characters, and the need to use sets of characters to place (extinct) taxa in this family. On this taxonomic basis we describe two new species in the hitherto monotypic fossil genus Palaeopsilotreta Wichard & Wang, 2017 (Odontoceridae), Palaeopsilotreta burmanica sp. nov. and P. cretacea sp. nov., redescribe the type species based on additional information, and describe features of the female, based on two specimens, one of which is embedded adjacent to a male identified as P. xiai. Males of Palaeopsilotreta bear bipectinate antennae; the antennae of the females are simple and filiform. Similarly, bipectinate antennae are present in the third species we describe, Bipectinata orientalis gen. et sp. nov., which otherwise lacks the character combinations associated with the Odontoceridae, but clearly can be assigned to the family Calamoceratidae.

Fossil Genus

The mid-Cretaceous Burmese amber from Kachin State of northern Myanmar provides a scanty but rather diverse fauna of sawflies. Herein Grandixyela rasnitsyni gen. et sp. nov. is described and illustrated on the basis of a well-preserved male specimen from Myanmar amber. The new fossil genus and species is characterized by wing venation and body characters, such as 15-segmented antenna with the first flagellomere distinctly shorter than the remaining, pterostigma narrow and completely sclerotized, 1-RS distinct (not dot-like), RS distal of 2r-rs gently S-shaped, ending to pterostigma beyond its apex for a short distance. A checklist and a review of known syspastoxyelid species are discussed. Additionally, our findings not only provide important morphological characters, especially the well-preserved details of the venation and genitalia, but also broaden new data on the Cretaceous diversity of symphytan wasps and further extend the records of syspastoxyelids to six genera and seven species.

Fossil Genus

The world catalogue of the family Ochteridae (Hemiptera: Heteroptera: Nepomorpha: Ochteroidea) is compiled. The fossil subfamily Propreocorinae Popov, Dolling & Whalley, 1994, recently excluded from Ochteridae by other authors, is formally raised to family rank as Propreocoridae stat. nov. The fossil genus Meropachys Popov, 1986 is found to be a junior homonym of Meropachys Burmeister, 1835 (Hemiptera: Heteroptera: Coreidae) and is replaced by a new substitute name, Yuripachys nom. nov., resulting in one new combination: Yuripachys dubius (Popov, 1986) comb. nov. Neochterus Mahner, 1993 (originally proposed as subgenus of Ochterus Latreille, 1807) is considered an unavailable name. Ochterus papaceki Kment & Carapezza sp. nov. is described and illustrated as a new species from the island of Socotra (Yemen) and Tanzania. Gender agreement in Ochterus paucistriata Baehr, 1990 is corrected to O. paucistriatus Baehr, 1990. The name Ochterus perbosci (Guérin-Méneville, 1843), an incorrect subsequent spelling of O. perboscii in prevailing usage, is fixed according to Article 33.3.1 of the ICZN (1999). The spelling of Angulochterus quadrimaculatus Yao, Zhang & Ren, 2011 is corrected according to Article 32.5.1 of ICZN (1999). The original publication of Ochterus barberi Schell, 1943, O. bidentatus Schell, 1943, O. hungerfordi Schell, 1943, and O. parvus Schell, 1943 is clarified. The name bearing types of Ochterus barberi, O. bidentatus, O. hungerfordi, O. parvus, O. perbosci, and Pelogonus splendidulus Montandon, 1898 (= Ocyochterus victor (Bolívar, 1879)) are considered as lectotypes. The family Ochteridae currently includes 3 recent genera and 88 described species group taxa (84 species and 4 subspecies): Megochterus Jaczewski, 1934 (2 species from Australia), Ochterus (80 species and 4 subspecies distributed worldwide), and Ocyochterus Drake & Gómez-Menor, 1954 (2 species from NW South America). The fossil record of Ochteridae currently includes 4 genera and 5 species: Angulochterus Yao, Zhang & Ren, 2011 (1 species from Early Cretaceous of China), Floricaudus Yao, Ren & Shih, 2011 (1 species from Early Cretaceous of China), Pristinochterus Yao, Cai & Ren, 2007 (2 species from Late Jurassic to Early Cretaceous of China), and Riegerochterus Popov & Heiss, 2014 (1 species from Miocene Dominican amber). In addition the fossil genus Yuripachys (1 species from Early Creatceous of Mongolia) is classified as Ochteridae incertae sedis, Propreocoris Popov, Dolling & Whalley, 1994 (1 species from Early Jurassic of England) as common ancestor of Ochteridae and Gelastocoridae in its own family Propreocoridae, and Grimaldinia Popov & Heiss, 2014 (1 species from Burmese Amber) and Heterochterus Evans, 1971 (1 species based on an isolated wing, Late Triassic of Australia) as Ochteroidea incertae sedis. The following new records are provided: Ochterus aeneifrons surinamensis Nieser, 1975 (Colombia), O. caffer (Stål, 1855) (Mozambique, Sudan), O. feae (Laos, Thailand), O. marginatus marginatus (Latreille, 1804) (China: Anhui, Shaanxi; Central African Republic; India: Rajasthan; Oman; Sudan), and O. nicobarensis Chandra & Jehamalar, 2012 (Myanmar). The distribution of all species is reviewed and the zoogeographic patterns and biodiversity of Ochteridae are discussed.

Abstract A new fossil genus and species of the subfamily Pselaphinae (Coleoptera: Staphylinidae), †Cretobrachygluta laurasiensis gen. et sp. nov., is described based on an exquisitely preserved specimen in mid-Cretaceous amber from northern Myanmar. The new genus possesses a series of characters diagnostic of the extant Brachyglutini: Brachyglutina (supertribe Goniaceritae), but it also exhibits several plesiomorphic traits that suggest a basal position within the tribe. The discovery of the first and oldest brachyglutine beetle in Burmese amber considerably improves our understanding of the early morphological evolution of Pselaphinae during the Mesozoic Era.

Fossil Genus

A new fossil genus of Bibionidae (Diptera: Bibionomorpha), Burmahesperinus gen. nov., from the mid-Cretaceous Burmese amber, is described and illustrated (type species Burmahesperinus antennatus sp. nov., the other two species included are B. conicus sp. nov. and B. pedicellatus sp. nov.). The new genus is tentatively placed in a new subfamily, Burmahesperininae subfam. nov. of the family Bibionidae. Its possible phylogenetic position is briefly discussed. The new genus, as well as the subfamily, possesses the wing venation similar to the recent genus Hesperinus Walker, 1848, in combination with Brachycera-like modification of both the male and female antenna and the overall habitus typical of fungus gnats (Sciaroidea).
