Muellerizomus DE FRANCESCO MAGNUSSEN & 2022, GEN. NOV.
† MUELLERIZOMUS DE FRANCESCO MAGNUSSEN & S.P. MÜLLER GEN. NOV. S.P. MÜLLER GEN. NOV. (FIGS 27–34) Z o o b a n k r e g i s t r a t i o n: u r n: l s i d: z o o b a n k. o r g: act: 1E280AB6-17C2-4F05-A4C4-E021DF9F2722 Type species: † Muellerizomus palicaudatus De Francesco Magnussen sp. nov. Remarks Specimens of this genus show asymmetrical tarsal spurs and also differ from species of Protoschizomidae by the lack of a pair of setae at the base of the anterior process and the presence of a distinct stalk at the male flagellum. They also differ from members of Megaschizominae by having a smaller body size, lack of eight or nine setae on their anterior process and the presence of only one pair of setae on the tergites II -VII. Therefore, they are clearly members of subfamily Hubbardiinae. The specimens cannot be assigned to any extant genus because of their combination of characters. Diagnosis † Muellerizomus differs from all other hubbardiid genera by the following combination of characters: propeltidium with a single median seta followed by three pairs of setae; eye spots present or absent; metapeltidium not divided; body without clavate setae; pedipalp trochanter with a mesal spur (equivocal in † Mu. amandae); anterodorsal margin of femur of leg IV produced at an angle of ~90°; tergite II with one pair of setae; tergites X–XII not elongated; tergite XII with posterodorsal process; male flagellum dorsoventrally flattened; female flagellum with three annuli. Etymology The genus name is a patronym for private collector Patrick Müller, who provided the specimen and numerous others for examination, with the common suffix -zomus, from the last letters of Schizomus. It is masculine in gender. Comparison † M u e l l e r i z o m u s s h a r e s c h a r a c t e r s w i t h † Groehnizomus, but the latter has corneate eyes and a divided metapeltidium (eye spots and metapeltidium not divided in † Muellerizomus). Secozomus Harvey, 2001b from the Seychelles is also similar, but it lacks a posterodorsal process, and the anterodorsal margin of femur IV is angled at> 90°.

Allodia Winnertz from the Himalayas, with nine species new to science (Diptera, Mycetophilidae)
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

A gamma-Poisson distribution of point to k nearest event distance
Distance sampling of events in natural or seminatural populations often indicates a larger variance in the distance to the kth nearest event than expected for events distributed completely at random. Overdispersion contributes to the well-known bias problem of distance sampling density estimators. Distance distribution models that accommodate overdispersion in the data should lead to more robust estimators of density. To this end we propose a gamma-Poisson distribution model for distances from a point to k nearest events. The model assumes a gamma distribution of local densities of randomly distributed events. Properties of the distribution and estimation of the parameters and event density are detailed for both constrained and unconstrained sampling. Four examples, one with simulated data from a known negative binomial distribution and three with simulated distance sampling in natural and seminatural stem-mapped tree stands, illustrate the promising performance of this new distribution, both as a model for distances and for density estimation. The modeling approach extends to other mixing distributions
