We present a protocol to establish a synthetic symbiosis between the mCherry-expressing Sodalis praecaptivus and the grain weevil host, Sitophilus zeamais. We describe steps to isolate grain weevil eggs, followed by microinjecting the bacterial symbiont into insect eggs using a modified Drosophila injection protocol, which leads to localization of bacteria in female insect ovaries. We then detail larval transplantation and visualization of bacteria in live insects using a fluorescence dissection microscope to assess the transgenerational transmission to offspring in weevils. For complete details on the use and execution of this protocol, please refer to Su et al. (2022).1 

Fourteen new species of chewing lice in the Brueelia-complex are described, from hosts in the Campephagidae. In addition, Malardifax a new subgenus of Guimaraesiella Eichler, 1949 is described for the species occurring on minivets (Campephagidae: Pericrocotus). The new species and their hosts are: Guimaraesiella (Guimaraesiella) nouankaoensis n. sp. from Coracina caledonica seiuncta Mayr & Ripley, 1941 and C. caledonica thilenii (Neumann, 1915); Guimaraesiella (Guimaraesiella) sphagmotica n. sp. from Coracina caeruleogrisea strenua (Schlegel, 1871) and C. caeruleogrisea adamsoni Mayr & Rand, 1936; Indoceoplanetes (Capnodella) kamphaengphetensis n. sp. from Lalage melaschistos avensis (Blyth, 1852); Indoceoplanetes (Capnodella) saucia n. sp. from Edolisoma montanum montanum (Meyer, 1874); Indoceoplanetes (Capnodella) subarcens n. sp. from Edolisoma melas melas (Lesson, 1828); Indoceoplanetes (Indoceoplanetes) cinitemnina n. sp. from Edolisoma melas melas (Lesson, 1828); Indoceoplanetes (Indoceoplanetes) ephippiformis n. sp. from Edolisoma montanum montanum (Meyer, 1874); Indoceoplanetes (Indoceoplanetes) fodincana n. sp. from Coracina papuensis oriomo Mayr & Rand, 1936, C. papuensis angustifrons (Salvadori, 1876), and C. papuensis elegans (Ramsay, 1881); Indoceoplanetes (Indoceoplanetes) incisoma n. sp. from Coracina macei siamensis (Baker, 1918) and C. macei rexpineti (Swinhoe, 1863); Indoceoplanetes (Indoceoplanetes) microgenitalis n. sp. from Coracina caeruleogrisea strenua (Schlegel, 1871); Indoceoplanetes (Indoceoplanetes) pterophora n. sp. from Coracina macei nipalensis (Hodgson, 1836); Indoceoplanetes (Indoceoplanetes) saburrata n. sp. from Coracina lineata ombriosa (Rothschild & Hartert, 1905); Indoceoplanetes (Indoceoplanetes) wandoensis n. sp. from Coracina novaehollandiae melanops (Latham, 1802); and Indoceoplanetes (Indoceoplanetes) zambica n. sp. from Coracina pectoralis (Jardine & Selby, 1828). Checklists and keys to the louse species of the Brueelia-complex parasitic on campephagid hosts are provided. 

Six new species of chewing lice in the Resartor-group (Brueelia-complex) are described and illustrated. They are: Aratricerca cerata n. sp. ex Zosterops capensis Sundevall, 1850; Aratricerca macki n. sp. ex Melidectes princeps Mayr & Gilliard, 1951 and Ptiloprora perstriata perstriata (de Vis, 1898); Aratricerca madagascariensis n. sp. ex Randia pseudozosterops Delacour & Berlioz, 1931; Turdinirmoides janigai n. sp. ex Prunella collaris nipalensis (Blyth, 1843) and P. collaris fennelli Deignan, 1964; Turdinirmoides rozsai n. sp. ex Carpodacus subhimachala (Hodgson, 1836); and Timalinirmus curvus n. sp. ex Yuhina castaniceps plumbeiceps (Godwin-Austen, 1877). A key to the species of Aratricerca, Turdinirmoides and Timalinirmus is provided. 

We describe and illustrate eight new species of chewing lice in the genus Philopterus Nitzsch, 1818, parasitic on hosts in the bird families Cardinalidae, Chloropseidae, Hirundinidae, Icteridae, Motacillidae, Paridae, and Vangidae from China, Peru, South Africa, Thailand, and the USA. They are: Philopterus coriaceus sp. nov. from Molothrus oryzivorus oryzivorus (Gmelin, 1788); P. hebes sp. nov. from Chloropsis aurifrons inornata Kloss, 1918 and C. cochinchinensis kinneari Hall & Deignan, 1956; P. micropunctatus sp. nov. from Anthus hodgsoni Richmond, 1907; P. afropari sp. nov. from Melaniparus cinerascens cinerascens (Vieillot, 1818); P. pseudhirundo sp. nov. from Pseudhirundo griseopyga Sundevall, 1850; P. sinensis sp. nov. from Hemipus picatus capitalis (Horsfield, 1840); P. stansburyensis sp. nov. from Pheucticus melanocephalus melanocephalus (Swainson, 1827); and P. trepostephanus sp. nov. from Tephrodornis virgatus fretensis Robinson & Kloss, 1920 and T. v. mekongensis Meyer de Schauensee, 1946. Philopterus hebes sp. nov. constitutes the first record of the genus Philopterus from the Chloropseidae. We also provide some notes on the morphology and status of Cypseloecus Conci, 1941.
