Puparia of a new whitefly, Aleuroparadoxus marisae García-Ochaeta and Dubey, new species (Hemiptera: Aleyrodidae), collected on leaves of Brosimum alicastrum Sw. in Santa Ana, Petén, Guatemala, and on Pimenta dioica (L). Merr. in Calzada Mopán, Dolores, Petén are described and illustrated. Drawings of morphological structures and differential diagnosis of the puparium are provided, and differences from congeners are discussed. A key to puparia of the Aleuroparadoxus Quaintance and Baker species is included.

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).

We describe a new species of Dichotomius Hope, 1838, from the D. agenor species-group from Costa Rica and Nicaragua: D. woodruffi Solís and Kohlmann, new species (Coleoptera: Scarabaeidae: Scarabaeinae). Based on this discovery, we confirm that Dichotomius enioi Montoya-Molina and Vaz-de-Mello, 2021 and D. agenor (Harold, 1869) are not currently distributed in Costa Rica. Instead, the only species of Dichotomius that are currently distributed in Costa Rica from the D. agenor species-group are D. centralis (Harold, 1869) and D. woodruffi. We discuss the distribution of the Dichotomius agenor species-group in Central America.
