Validation of \u3ci\u3eChrysina valentini\u3c/i\u3e Zubov and Ivshin, 2019 (Coleoptera: Scarabaeidae: Rutelinae) by morphometric and cuticular reflectance analyses

Micromorphometric analyses of genital capsules and comparison of adult cuticular reflectance of two species of Chrysina Kirby (Coleoptera: Scarabaeidae: Rutelinae) support the status of C. valentini Zubov and Ivshin, 2019 as a valid species. Compared with its closest relative C. optima (Bates, 1888), capsules of C. valentini are proportionately wider at the base of the parameres than those of C. optima, and taper toward the apex more abruptly. Reflectance of C. valentini under natural light appears slightly greenish while C. optima is uniformly reddish. The number of teeth on the protibia and the shape of the mesosternal process, characters cited by Zubov et al. (2019) to distinguish the two species, did not prove reliable. Resumen.

En comparación con su pariente más cercano C. optima (Bates, 1888), las cápsulas de C. valentini son proporcionalmente más anchas en la base de los parameres que las de C. optima, y se estrechan hacia el ápice más abruptamente. La reflectancia de C. valentini bajo luz natural apa­rece ligeramente verdosa mientras que C. optima es uniformemente rojiza.

Comparison of Two Parameter Estimation Techniques for Stochastic Models

Parameter estimation techniques have been successfully and extensively applied to deterministic models based on ordinary differential equations but are in early development for stochastic models. In this thesis, we first investigate using parameter estimation techniques for a deterministic model to approximate parameters in a corresponding stochastic model. The basis behind this approach lies in the Kurtz limit theorem which implies that for large populations, the realizations of the stochastic model converge to the deterministic model. We show for two example models that this approach often fails to estimate parameters well when the population size is small. We then develop a new method, the MCR method, which is unique to stochastic models and provides significantly better estimates and smaller confidence intervals for parameter values. Initial analysis of the new MCR method indicates that this method might be a viable method for parameter estimation for continuous time Markov chain models

A new species of \u3ci\u3eChrysina\u3c/i\u3e Kirby (Coleoptera: Scarabaeidae: Rutelinae) from the Sierra Madre Occidental of Mexico, with notes on the type locality of \u3ci\u3eChrysina adelaida\u3c/i\u3e (Hope, 1841)

This paper presents a taxonomic review of the genus Boreocanthon Halffter, restored generic sta­tus, a group of ball-rolling (telocoprid) dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) endemic to North America. The genus, heretofore treated as a subgenus of Canthon, comprises 13 species, each keyed, diagnosed, illustrated and presented with information on distribution, relationships, and biology (*signifies restored generic combination): *Boreocanthon ateuchiceps (Bates, 1887); B. coahuilensis (Howden, 1966); *B. depressipennis (LeConte, 1859c); *B. ebenus (Say, 1823); *B. forreri (Bates, 1887); *B. integricollis (Schaef­fer, 1915); *B. lecontei (Harold, 1868); *B. melanus (Robinson, 1948); *B. praticola (LeConte, 1868); *B. probus (Germar, 1823); *B. puncticollis (LeConte, 1866); *B. simplex (LeConte, 1857); as well as Boreocanthon halff­teri Edmonds here described as a new species. Other actions taken are a) Canthon mixtus Robinson declared junior subjective new synonym of Boreocanthon puncticollis; b) Canthon bisignatus Balthasar, 1939, declared junior subjective new synonym of Boreocanthon simplex; c) Boreocanthon coahuilensis (Howden) new ge­neric combination; and d) neotype designated for the type species of the genus Boreocanthon, Ateuchus ebenus Say, 1823, here Boreocanthon ebenus (Say). La localidad tipo aproximada de Chrysina adelaida (Hope, 1841) (Coleoptera: Scarabaeidae: Rutelinae) se fija en las montañas del sureste de México. Chrysina occidentalis Robacker and Hawks se describe como una nueva especie de la Sierra Madre Occidental en el noroeste de México con base en comparaciones morfométricas de adultos y cápsulas genitales con las de C. adelaida del sureste de México y con las de C. adelaida (de los autores) de la vecina estados al sur de la Sierra Madre Occidental
