Calosima smithi n. sp. (Lepidoptera: Gelechioidea: Blastobasidae) is described from specimens reared in Kenya from swollen thorn domatia of Vachellia drepanolobium (Fabaceae). Illustrations of the adult and male genitalia are provided.

Xyela davidsmithi Blank and Kramp sp. n. is described from the Sierra Nevada of California. Morphological characters place it into the X. alpigena group. Unlike other members of this group, whose larvae feed inside staminate cones of species of Pinus (Strobus), larvae of X. davidsmithi identified by COI barcoding have been extracted from staminate cones of P. (Pinus) jeffreyi. Field observations on imagines of X. brunneiceps Rohwer, 1913 indicate that this species is oligophagous on P. (S.) flexilis in Colorado and on P. (S.) strobiformis in Arizona. A key to the Nearctic species of the X. alpigena group is provided.

A new genus of eucoiline wasps, Humboldteria, new genus is described from the Neotropical Region. The type species of the genus is H. davesmithi, new species; other new species include H. maurofrons, new species, H. kerri, new species, H. montanai, new species, and H. kojaki, new species. The phylogenetic analysis presented herein recovers the new genus in the Ganaspini, and sister-group with either Glauraspidia (Bayes analysis) or Steleucoela (parsimony analysis). Distribution maps and a key to species are provided.

In 2014, 369 species of caddisfly (Trichoptera) had been recorded from the state of Virginia. In the last two plus years two more species have been newly found in the state, bringing the total to 371 species; Hydropsyche carolina Banks and Beraea fontana Wiggins, with the latter being the southernmost record for the species as well as a new family and genus for the state. The presence of Theliopsyche grisea (Hagen) is confirmed with the collection of a male, and further records of noteworthy collections are mentioned.

The species of Eopelma Gibson (Hymenoptera: Eupelmidae: Neanastatinae) are revised. Six described species are recognized, Eopelma davidsmithi, n. sp. (♂, Borneo: Sabah), Eopelma gibsoni Fusu and Polaszek (♂, Borneo: Sarawak), Eopelma habrotatos, n. sp. (♀, Malaya), Eopelma mystax Gibson (♀, Philippines), Eopelma viridifrons, n. sp. (♂, Thailand), and Eopelma xuthocephala, n. sp. (♂, Nepal). One other partial, disarticulated male from Indonesia (Sulawesi) that represents another new species is compared to the other species but because of its condition is not described. The genus is redescribed and the described species are keyed and illustrated through macrophotography. Apparent sexual dimorphism in color and setal patterns of the fore wings and in structure and setal patterns of the mesotarsi are also discussed and hypothesized as important in male courtship displays for pre-copulatory species recognition.

A new species, Scolioneura smithi, probably associated with an ericaceous host is described. The two American species of Scolioneura are quite distinct from the known European species and differences are discussed. A key to females of Nearctic species of Scolioneura is provided.

Hoplocampa smithiana, new species from China, Yunnan, is described from an adult female. Larval host is probably Sorbus ursina (Rosaceae). It is compared with H. sinobirmana Malaise, the only other of the now three Hoplocampa species recorded in the Oriental Realm that is likewise pale-coloured, and keyed together with three further Palaearctic species which have a similar colour pattern, and are associated with Sorbus species as hosts. Closest to H. smithiana among known species in CO1 barcoding and morphology is however H. oregonensis (Ashmead), distributed in North West America, also with a Sorbus species as recorded host. It is tentatively suggested that H. smithiana and H. oregonensis represent one of the few recorded cases of a tenthredinid lineage with a disjunct East Asian-North American distribution.

Zhuangzhoua smithi Liu, Niu and Wei, gen. et sp. nov. is described from China. It is a member of Anhoplocampini of Hoplocampinae, Tenthredinidae. A key is provided for separating Zhuangzhoua and Anhoplocampa Wei, 1998.

Oregmopyga davesmithi Miller and Stocks n. sp. collected on grass (Poaceae) from Arizona and Mexico is described. Keys are included for the separation of Oregmopyga species based on the adult female, second-instar male, second-instar female, and first-instar nymph. Detailed illustrations and descriptions are included for the adult female, second-instar male, second-instar female, and first-instar nymph of the new species, which is most similar to O. tippinsi Miller and Miller.

The phylogeny of the Agathidinae is analyzed employing 45 agathidine genera, 172 Agathidinae operational taxonomic units, and sequences from the mitochondrial gene COI and the nuclear ribosomal gene 28S. The tribal classification is revised; two new tribes are proposed, i.e., Lytopylini and Agathirsini. Mesocoelini n. stat., is included as a tribe of Agathidinae for the first time. The concepts of Earinini and Agathidinini are revised. Biroia Szépligeti, 1900, is synonymized with Megalagathis Schulz, 1906 (emendation for Megagathis Krechbaumer 1894). A new genus and species from Colombia, Smithagathis davidsmithi Sharkey are erected. The currently recognized 61 genera of Agathidinae are presented in a list which includes their tribal placement. Biroia Szépligeti, 1900, and its junior synonym Isoptronotum Enderlein, 1920 are synonymized with Megalagathis Schulz, 1906, new synonymies. The species of Biroia are moved to Megalagathis as new combinations.

Arge albocincta group is defined to include eight Asian species: A. albocincta (Cameron, 1876) from India (Himachal Pradesh, Uttarakhand, Meghalaya) and Nepal, A. zonata Jakowlew, 1891, from China (Sichuan), A. procer (Konow, 1906) from India (Meghalaya), revised status, A. megacincta Wei, in Wei and Wen, 1997, from China (Guizhou, Guangxi), A. paracincta Wei, 2005, from China (Guizhou, Zhejiang), A. malaisei Shinohara and Hara, n. sp. from Myanmar, A. jakovlevi Gussakovskij, 1935, from China (Sichuan), and A. davidi Shinohara and Hara, n. sp. from China (Taiwan). Arge malaisei and A. davidi are described and other species are redescribed mainly based on the type material. Hylotoma albobalteata Cameron, 1899, is a new synonym of A. albocincta. Arge procer is revived from synonymy with A. albocincta. Lectotypes are designated for Hylotoma albobalteata Cameron, 1899, and Bathyblepta procer Konow, 1906. A key is given for separating females of the eight species.

Tianmuthredo Wei, 1997 is recorded for the first time in the Palearctic realm, and Tianmuthredo davei Taeger and Kramp, new species is described from the Primorskij Kraj in the Russian Far East. The placement of the genus within Tenthredininae is discussed.

The African fauna of the rare family of parasitoid wasps, Orussidae, is reviewed. Five genera with 24 valid species are recognized. Chalinus davidi Vilhelmsen n. sp. is described; the male of Chalinus albitibialis Vilhelmsen, 2005, the male of Leptorussus madagascarensis Vilhelmsen, 2007 and the female of Orussus smithi Blank et al., 2006 are described. A neotype is designated for Oryssus plumicornis Guérin-Meneville, [1849] to properly define the genus-group name Chalinus Konow, 1897. Chalinus braunsi (Enslin, 1911), C. orientalis Guiglia, 1937 and C. somalicus Guiglia, 1935 are regarded as new junior synonyms of C. plumicornis. Leptorussus kwazuluensis Vilhelmsen, 2003 is regarded as a new junior synonym of L. africanus Benson, 1955. Distribution records for specimens examined by us are listed. The Afrotropical component of the African orussid fauna shows a high degree of endemism, with two endemic genera and 13 endemic species; only Chalinus timnaensis Kraus, 1998 and Pseudoryssus niehuisorum Kraus, 1998 have a cross-Saharan distribution. In contrast, there are only three species of Orussidae occurring exclusively in North Africa. An additional six North African species also occur outside Africa, in adjacent parts of the Palaearctic. The Atlas Mountain range spanning Morocco, Algeria and Tunisia is a hotspot for orussid diversity, nine species having been recorded from there. The current Afrotropical assemblage of orussids are a result of several independently derived lineages, some possibly resulting from vicariance events dating as far back as the Late Cretaceous. The North African orussids have probably appeared as the result of several dispersal or speciation events, some putatively occurring as recently as the Pleistocene.

The present short paper is a personal gift for the 80^th birthday of an outstanding American entomologist, Dr. David R. Smith (Washington), who has made an enormous contribution to the taxonomic and faunistic study of the order Hymenoptera of the World, especially the “Symphyta,” Trigonalidae, and Aulacidae.
