Lygistorrhina (Probolaeus) acahuizotla sp. nov., is described and illustrated based on adults from the locality of Acahuizotla in the state of Guerrero, Mexico. The species is related to Lygistorrhina (Probolaeus) alexi Huerta & Ibáñez-Bernal. The male is distinguished mainly from other congeneric species by the presence of a pair of preapical setae on the mediotergite, pale-yellow fore coxa, with brown pigmentation medially, and “U-shaped” tegmen. New records of Lygistorrhina (Probolaeus) alexi Huerta & Ibáñez-Bernal from Tecpan de Galeana, in the state of Guerrero and from Biology Station of Chamela, in the state of Jalisco, both in west Mexico, are added. A key to the species of Lygistorrhina from Mexico is provided.

New collection records for Calusamyia hribari Coher (Diptera: Keroplatidae) are presented. Sufficient material has been amassed to make some statements about the species’ distribution, seasonality, and morphology. Calusamyia hribari occurs throughout the inhabited Florida Keys, from Key Largo to Key West. New island records include Boca Chica Key, Crawl Key, Summerland Key, Geiger Key, Dredger’s Key, Upper Matecumbe Key, Key Largo, Long Key, Tavernier, Windley Key, and Fat Deer Key. As yet it has not been collected from any uninhabited islands within wildlife refuges. About five times more males than females have been collected. Most specimens have been collected in the summer months, with May being the peak of abundance in traps. Females have two spermathecae, similar to other keroplatids.

The dipteran family Bolitophilidae, with the single extant genus Bolitophila, is a small family of mycophagous flies. In marked contrast to related families such as Sciaridae and Mycetophilidae, the family has a poor fossil record with no definite species assigned to the genus. In addition, the position of the extinct Cretaceous subfamily Mangasinae Kovalev, 1986 (described in Bolitophillidae) has been controversial and it has been suggested that species in this clade may belong to other sciaroid families. This situation is made worse by misplacement of the type specimen. We herein describe two new species of Bolitophila, Bolitophila warreni sp. nov. from the 46-million-year-old Kishenehn Formation in Montana, USA and Bolitophila rohdendorfi sp. nov. from Baltic amber. Bolitophila pulveris Lewis, 1969 is reassigned to Sciaroidea incertae sedis. The subfamily Mangasinae is reviewed and its position within the Bolitophilidae confirmed. Two new species of Mangas, M. kovalevi sp. nov. and M. brevisubcosta sp. nov., both from the Lower Cretaceous of Khasurty in Western Transbaikalia, are described.

The Coal Creek Member of the Kishenehn Formation in northwestern Montana, USA, is an emerging middle Eocene Lagerstätte. While fish, plant, mammal and molluscan fossils are present, the most numerous and well-preserved fossils are those of insects. In this study, we initiate an effort to enumerate, at the family level, the diversity of flies (Insecta: Diptera) at this locality. Seventeen specimens from 17 different families (15 families with Limoniinae and Cylindrotominae within Tipulidae s.l.), 15 new species and three new genera are described. These include Tipula fji sp. nov. (Tipulidae), Ellipteroides kishenehn sp. nov. (Limoniidae), Cyttaromyia lynnae sp. nov. (Cylindrotomidae), Sylvicola silibrarius sp. nov. (Anisopodidae), Efcookella nigra sp. nov. (first fossil known in the genus) (Scatopsidae), Bibiodes kishenehnensis sp. nov. (Bibionidae), Eosciarites hermes gen. et sp. nov. (Sciaridae), Rymosia hypnolithica sp. nov. (Mycetophilidae), Litoleptis araeostylus sp. nov. (Rhagionidae), Kishenehnoasilus bhl gen. et sp. nov. (Asilidae), Drapetis adelomedos sp. nov. (Hybotidae), Salishomyia eocenica gen. et sp. nov. (Dolichopodidae), Agathomyia eocenica sp. nov. (first known fossil in genus) (Platypezidae), Lonchoptera eocenica sp. nov. (Lonchopteridae) and Aenigmatias kishenehnensis sp. nov. (Phoridae). Two specimens in the families Psychodidae and Pipunculidae are described but not assigned to a genus. In addition, we revise several related fossil species housed at the NMNH. Asilopsis fusculus Cockerell, 1921, formerly described in Asilidae, is transferred to Cyttaromyia (Cylindrotomidae) as C. fuscula, Sciara florissantensis Cockerell, 1917 is assigned to Sciaroidea incertae sedis, and Sciara gurnetensis Cockerell, 1916, Sciara lacoei Cockerell, 1915 and Sciara protoberidis Cockerell, 1915, are assigned to Sciaridae incertae sedis. Given their diversity and high degree of preservation, continued characterization of the Coal Creek Member fossils may help elucidate the Eocene radiation of Diptera in North America.

Blue shining fungus gnats (Diptera) had been long reported in the Waitomo caves of New Zealand (Arachnocampa luminosa Skuse), in stream banks of the American Appalachian Mountains (Orfelia fultoni Fisher) in 1939 and in true spore eating Eurasiatic Keroplatus Bosc species. This current report observes that similar blue light emitting gnat larvae also occur nearby the Betary river in the buffer zone of High Ribeira River State Park (PETAR) in the Atlantic Forest of Brazil, where the larvae were found when on fallen branches or trunks enveloped in their own secreted silk. The new species is named Neoceroplatus betaryiensis nov. sp. (Diptera: Keroplatidae: Keroplatinae: Keroplatini) based on a morphological analysis. Neoceroplatus betaryiensis nov. sp. larvae emit blue bioluminescence that can be seen from their last abdominal segment and from two photophores located laterally on the first thoracic segment. When touched, the larvae can actively stop its luminescence, which returns when it is no longer being agitated. The in vitro bioluminescence spectrum of N. betaryiensis nov. sp. peaks at 472 nm, and cross-reactivity of hot and cold extracts with the luciferin-luciferase from Orfelia fultoni indicate significant similarity in both enzyme and substrate of the two species, and that the bioluminescence system in the subfamily Keroplatinae is conserved.

Two new species, Manota williamsi sp. n. and Manota kerri sp. n., are described from Australia and Papua New Guinea, respectively. The former represents the second Manota species recorded from continental Australia. Characterised by setoseanepisternum and non-setose laterotergite, M. williamsi is similar to M. gemella Hippa, 2007, but the presence of themid tibial organ would group it together with five species from New Zealand. Manota kerri resembles M. alulata Kurina& Hippa, 2015 in having a bilobed gonostylus and sternite 9 entirely fused with the gonocoxa, but differs by other details of the hypopygium.

The first record of the genus Micrapemon Edwards from Mexico is presented, with the description and illustration of a new species, Micrapemon maya spec. nov., based on adult males collected with Malaise traps from Yucatan (natural reserves of Ria Celestun and Ria Lagartos). The new species from Mexico is compared with the two previously known species from the Neotropical region, Micrapemon majusculum (Edwards) and Micrapemon parvum (Williston). A key is included to the species of the genus.

Amerikeroplatus dimorphicus n. gen. et n. sp. is described from Guatemala and compared with the similar Keroplatini genera Pseudochetoneura Ševčík and Asiokeroplatus Ševčík. The new genus is distinctive because it lacks the typical fusion of M and R (radiomedial fusion, RS+M) which is found in all but a few species-poor, and apparently unrelated, genera of keroplatids. Also unusual is the absence of vein R2+3 and the strong sexual dimorphism in the thorax; males are dark brown and females bright orange.

The genus Cabamofa, previously containing only C. mira from Costa Rica (Jaschhof 2005), is shown here to have a second species in Thailand, which is described and named C. orientalis sp. nov. The new species is known from a single male collected by the TIGER Project (Thailand Inventory Group for Entomological Research), a mass-sampling program to  inventory  insect  diversity  in  Southeast  Asia  (Plant  et  al.  2011;  http://sharkeylab.org/tiger,  accessed  14  December  2018). As the circumstances of finding indicate, C. orientalis is a decidedly rare species, an attribute applying to perhaps one third of all tropical arthropods (Lim et al. 2012) and most Sciaroidea incertae sedis (Jaschhof 2017), including the Costa Rican C. mira. The latter species was originally described from two females, which were Malaise trapped in 2003 in lowland rain forest (Jaschhof 2005), while a conspecific male, a museum specimen collected in 1922 in an unknown habitat, was detected and described subsequently (Amorim & Rindal 2007). Cabamofa is one of nearly 20 sciaroid genera  whose  family  affiliation  has  not  yet  been  resolved  (Jaschhof  2017),  but  there  is  morphological  evidence  suggesting its close affinity to other Sciaroidea incertae sedis, such as Rogambara Jaschhof, 2005, Ohakunea Tonnoir & Edwards,  1927,  and  Colonomyia  Colless,  1963.  These  four  genera  together  form  the  Ohakunea  group  of  Jaschhof  (2005), or the Ohakuneinae (as a subfamily of the broadly conceived family Rangomaramidae) of Amorim & Rindal (2007). Recent molecular work (Ševčík et al. 2016, Kaspřák et al. 2019) suggests a more distant phylogenetic position of Ohakunea to other Sciaroidea incertae sedis. The obvious conflict here between morphological and molecular evidence is stimulating fresh interest in the “incertae sedis issue”, as proven by the present contribution. The morphology of C. orientalis  provides  no  new  clues  as  to  the  systematic  position  of  Cabamofa,  or  the  Ohakunea  group,  but  reveals  characters that were previously not known to occur in Cabamofa. The delimitation of this genus is briefly reviewed below. Our finding of C. orientalis extends the geographic distribution of Cabamofa from the New World to the Old World (Oriental) tropics, which consorts with the disjunct (Neotropical-Australasian) areas found in both Colonomyia and Ohakunea. Morphological terminology used here is in accordance with that by Cumming & Wood (2017).

An extensive collection of fungus gnats from Nepal and Bhutan, deposited at Kyushu University Museum in Japan, has been examined and revealed nine species of Allodia Winnertz, 1864 new to science: Allodia caligata Magnussen, sp. n., A. dibolia Magnussen, sp. n., A. shimai Magnussen, sp. n., A. spathulata Magnussen, sp. n., A. horologia Magnussen, sp. n., A. himalayensis Magnussen, sp. n., A. nepalensis Magnussen, sp. n., A. thudamensis Magnussen, sp. n., and A. scalprata Magnussen, sp. n. All specimens were collected at high altitudes in the central and eastern Himalayas. The species all belong to the subgenus Allodia s. str. and constitute the first records of the genus Allodia in Nepal and Bhutan. Brevicornu nigrofasciatum (Brunetti, 1912) comb. n., originally described from northern India, is transferred from Allodia based on the original description. A key for the identification of the new species is provided.
