The pantropical genus Schefflera J. R. Forst. & G. Forst. (Araliaceae) was recently found to be polyphyletic, making it necessary to restrict the generic name to a small clade in the southwest Pacific and to transfer the members of the four remaining clades to other genera. Recent studies of the Neotropical clade have shown that it comprises five morphologically and geographically coherent subclades, each of which is being recognized as a separate genus. In the present synopsis, Crepinella Marchal is resurrected to include the 33 currently recognized species and four infraspecific taxa belonging to one of these subclades, necessitating 36 new combinations (32 species, two subspecies, and two varieties); two names are also lectotypified. Members of Crepinella can be recognized by their leaves with coriaceous leaflets and small stipular ligules, compoundumbellate inflorescences, and 2- to 5-carpellate ovaries, coupled with a distribution that is largely restricted to montane vegetation on the sandstone tepuis of the Guiana Shield, with just three species occurring on sandstone substrates elsewhere in Brazil, Colombia, Ecuador, and Peru.

The background to and status of the genus Searsia F.A.Barkley (Anacardiaceae) is discussed and reasons given as to why it is the correct name for those Old World species in the Rhus complex fonnely regarded as subgenus  Thezera (DC.) K.Koch (section Gerontogeae Engl.). An annotated list of all the accepted 111 species and 28 fiirther infraspecific taxa in Searsia is presented, and where necessary, new combinations are made and types are designated.

A New Species

The small chelonine tribe Adeliini is one of the derived groups with the postpectal carina absent, which is considered to be an apomorphic character for the Cheloninae. Adeliine genera generally exhibit a narrow endemism although the genus Adelius is widely distributed. Adeliini are reported from the Indian subcontinent for the first time with the description of a new genus and a new species, Carinadelius medicus Ranjith & van Achterberg gen. et sp. nov. from south India. A revised key to the genera of Adeliini is provided with the illustrations of all included genera. The genus Myriola, which was previously included under Adelius, is re-instated based on morphological characters. The New World species of the genus Paradelius are transferred to Sculptomyriola Belokobylskij: Sculptomyriola neotropicalis (Shimbori & Shaw, 2019), S. nigra (Whitfield, 1988) and S. rubra (Whitfield, 1988) are new combinations.

A field survey of sternorrhynchous Hemiptera in Belize, principally conducted within the Chiquibul Forest Reserve, has revealed in excess of 180 species of whiteflies, over 40 of which belong to the subfamily Aleurodicinae. Provided here are a key to all the neotropical genera of Aleurodicinae, an illustrated account of all definable Belize species of Aleurodicinae, and a review of literature that is relevant to systematic studies of New World species in both whitefly subfamilies. Four appendices provide a check list of Belize members of the Aleurodicinae, a list of their known host plants in Belize, a list of nomenclatural changes proposed by this work, and a protocol for the field collection and subsequent laboratory preparation of whitefly specimens. As detailed in Appendix 3, this account proposes one revised subfamilial placement, three new generic synonymies, six new specific synonymies and 12 new combinations; 18 new species are here described.

Despite over 60 years' worth of taxonomic efforts, the relationships between sugarcane (Saccharum hybrid cultivars), Sorghum and their closest evolutionary relatives remain largely unresolved. Even relationships between generally accepted genera such as Miscanthus and Saccharum have not been examined in any large-scale molecular detail. Genera such as Erianthus, Miscanthidium and Narenga pose even greater taxonomic contention. Erianthus is not monophyletic and Erianthus sect. Ripidium (Valdés and Scholz 2006, Lloyd Evans et al. 2019a; Welker et al. 2019) represents a distinct and separate genus, Tripidium Scholz. Miscanthidium is placed within Miscanthus by many workers, whilst the New World Erianthus species and Narenga are currently placed within Saccharum. As these species represent a significant portion of the gene pool that sugarcane breeders use for introgression into sugarcane, their taxonomic placement and relationships to Saccharum are of significant economic import. Erianthus species from the Americas have not been significantly employed in sugarcane breeding and may represent an untapped genetic resource. In an attempt to resolve the taxonomic relationships of these genera, we have assembled three novel chloroplasts, from Miscanthidium capense, Miscanthidium junceum and Narenga porphyrocoma (this latter assembled from transcriptomic and long read data). In parallel, five low copy number loci have been assembled from species within Saccharum, Miscanthus, Sarga and Sorghum. Phylogenetic analyses were performed using both low copy number genes and whole chloroplasts. The phylogenetic results were compared with karyotype data to circumscribe the genera most closely related to sugarcane. We reveal that genera Miscanthus and Saccharum are monophyletic and have never undergone polyploidization outside their own genera. Genera Erianthus, Miscanthidium and Narenga are allopolyploids, which excludes them from being members of Saccharum and Miscanthus. Moreover, all three of these genera have divergent evolutionary histories. We therefore support the use of the genera Miscanthus, Miscanthidium, Erianthus (for the New World Species) and Narenga for those species and genera most closely allied to Saccharum. Our data demonstrate that all these genera should be excluded from Saccharum sensu lato.

The first comprehensive revision of the Nearctic and Neotropical species of the genus Dinotrema Foerster, 1863 is provided. Twenty-two species of this genus are redescribed and illustrated. The following new combinations are suggested: D. floridensis (Shenefelt, 1974), comb. nov.; D. ephemera (Viereck, 1917), comb. nov.; D. foliformis (Fischer, 1969), comb. nov.; D. latitergum (Fischer, 1969), comb. nov.; D. lobidens (Fischer 1969), comb. nov. and D. longibasis (Fischer 1969), comb. nov. Dinotrema bucculatricis (Fischer 1969) is synonymized with D. angusticorne (Fischer 1969), syn. nov. Dinotrema sublatitergum (nom. nov.) is new name for junior homonym Dinotrema latitergum (Fischer, 1975), not D. latitergum (Fischer, 1969). The key to all New World species of Dinotrema is compiled for the first time.

AbstractThe New World species of Pseudonapomyza Hendel are reviewed. Only two species of the genus were previously known to occur in the Nearctic region: P. atra (Meigen) and P. lacteipennis (Malloch). Pseudonapomyza europaea Spencer and P. asiatica Spencer are here recorded for the first time in the Nearctic region and P. asiatica is recorded for the first time in Costa Rica and Venezuela. A key is provided to identify the four known New World species of Pseudonapomyza.

A New Species

Distinctive, remarkable specimens from Bauru, São Paulo state, Brazil are recognized as a new species of the genus Laemophloeus Dejean (sensu stricto), which is described and illustrated in this paper. Laemophloeus souzalimai sp. nov. is most similar to L. germaini Grouvelle and can be readily distinguished from all New World species of the genus by the dorsal color testaceous, without elytral maculae, antennal club of 6 antennomeres, genal processes anteriorly projected, male head with somewhat pedunculated eyes, and frons with a broad, V-shaped impressed line. Additionally, the preexisting key to Laemophloeus species with antennal club of 6 or more antennomeres is modified to include the new species, and new records for five Brazilian species of the genus are provided.
