A new flower fly genus (Diptera, Syrphidae), Biema Huo & Zhao gen. nov. from China is described based on two new species: Biema wanglangensis Huo & Zhao gen. et sp. nov. (designated as type-species) and Biema qilianensis Huo & Liu gen. et sp. nov. The new genus can easily be distinguished by the following morphological features: head, mesonotum and scutellum black; postpronotum without pile; metasternum not reduced, posterior margin shallowly concave; katepisternum only with ventral pile patches; alula narrow, as wide as basal width of cell c; male postabdomen conspicuously more swollen than other segments, surstylus and postgonite complex, phallus unsegmented. The results of our Bayesian inference and Maximum Likelihood analysis based on sequences of the Cytochrome c oxidase subunit I (COI) gene, as well as the species delimitation tests, support the separation of Biema Huo & Zhao gen. nov. from its related taxa. Additionally, an identification key to the genera of the tribes Bacchini and Melanostomini occurring in China is provided.
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.

New taxonomic data on some species of Atherigona Rondani are provided. This is partly based on recently discovered types of A. laevigata (Loew), A. maculipennis Stein, A. magnipalpis Stein, A. nigrithorax Stein and A. subnigripes (Karsch), and partly on new material that has become available. Among this new material is a new species here described: Atherigona zongoi sp. nov. The newly discovered types of Atherigona nigrithorax Stein and A. subnigripes (Karsch) are redescribed. The status of a specimen of Coenosia humeralis found among material in the Smithsonian Institution and incorrectly labelled as the type of Atherigona humeralis is clarified. The puparium of A. varia (Meigen) is partially described for the first time. New records are given for several species and distribution is updated.
Four new species of the braconid wasp genus Hecabolus Curtis, 1834 (Doryctinae Foerster, 1863) are described for the Neotropical region in south and southwestern Brazil: H. acutus sp. nov., H. chrisaxeli sp. nov., H. gavinbroadi sp. nov., and H. transversalis sp. nov. We also report the morphological variation of females and males of H. mexicanus Zaldívar-Riverón & Belokobylskij, 2009, originally described based on a single female, and provide its first precise geographical distribution records. An updated key to the 13 described species of Hecabolus is provided.
Three new species of the family Pyrgodesmidae Silvestri, 1896 from the Udzungwa Mountains are described: Cryptocorypha geminiramus sp. nov., Cryptocorypha cactifer sp. nov., and Cryptocorypha exovo sp. nov. Several additional, unidentifiable pyrgodesmids from the Udzungwa Mountains are recorded. Elythesmus enghoffi Hoffman, 1978 (Cryptodesmidae Karsch, 1880), is recorded from the East Usambara (type locality), West Usambara, Uluguru, Nguru (Kanga) and Udzungwa Mountains, and its variation in size and body ring numbers is analyzed. The surface sculpture of pro- and metazonites is discussed.
Examination of Coccinellidae material recently collected from Napo Province in Ecuador revealed 38 species of ladybird beetles, of which six are new: Chnoodes yanayacu sp. nov., Cyrea mcclarini sp. nov., Eupalea borowieci sp. nov., Exoplectra misahualli sp. nov., Hyperaspis rutai sp. nov., Toxotoma gonzalezi sp. nov. Seven species are recorded for the first time from Ecuador: Cyrea noticollis (Mulsant, 1850), Eupalea formosa Mulsant, 1850, Epilachna transverselineata (Mader, 1858), Psyllobora marshalli Crotch, 1874, Toxotoma fuscopilosa (Weise, 1902), Toxotoma taeniola (Gordon, 1975), Zenoria linteolata Mulsant, 1850. For three species: Epilachna obtusiforma Gordon, 1975, Hinda ecuadorica Gordon & Canepari, 2013 and Siola atra González, 2015, supplementary notes on the original descriptions are provided. New name combinations are proposed for six species, which are transferred to the genus Toxotoma Weise, 1900: Toxotoma aequatorialis (Gordon, 1975), Toxotoma chigata (Gordon, 1975), Toxotoma flavocirculus (González, 2015), Toxotoma fuscopilosa, Toxotoma hybridula (Gordon, 1975), Toxotoma taeniola. The occurrence of Scymnus interruptus (Goeze, 1777) in Ecuador is also confirmed.
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).

Martensina thailandica gen. et sp. nov., a freshwater ostracod species representing a new subfamily, Martensininae subfam. nov., in the family Cyprididae, is here described from a swamp in Maha Sarakham Province, Thailand. The new genus and species is mainly characterized by the 7-segmented antennula which has a Rome organ and remarkably long aesthetasc ya, the morphology of the sexually dimorphic antenna (A2), the markedly elongated A2 terminal segment, the short and thin α- and β-setae on the mandibular palp, the elongated terminal segment of the maxillula, the obviously 2-segmented male prehensile palp, the presence of d1 and d2 setae on the protopod of the second thoracopod (T2), the sexually dimorphic T2, the distinctive terminal segment of the third thoracopod bearing three long setae, the well-developed caudal ramus, the large hemipenis which has a complex internal structure, and the Zenker organ with funnel-shaped ends and numerous spiny whorls.
Rhytidaphora Reshchikov & Quicke gen. nov. (type species Rhytidaphora thailandica Reshchikov & Quicke gen. et sp. nov.) from Thailand is described and illustrated. It belongs to the tribe Euryproctini of the subfamily Ctenopelmatinae (Hymenoptera, Ichneumonidae) based on the absence of glymma and the subapical notch on the ovipositor. The new taxon differs from all other genera of Euryproctini by the occipital carina being broadly incomplete dorsally, the hypostomal carina joining the occipital carina shortly before the base of the mandible, distinctly pectinate tarsal claws, and immovably fused and strongly sculptured second and third metasomal tergites.
