Necroscia affinis (Gray, 1835) was originally described from India. The holotype of affinis lacks the abdomen and consequently this species cannot be reliably distinguished from several similar species. Lectotypes are selected for Necroscia pallida (Redtenbacher, 1908) and Necroscia fragilis (Redtenbacher, 1908), and both species are illustrated. Necroscia pallida (Redtenbacher, 1908) is reinstated as a valid species. It is proposed that Necroscia fragilis (Redtenbacher, 1908) be used for the species that occurs in Peninsular Malaysia and Singapore. A two-legged N. pallida is recorded: the first record of a two-legged phasmid found in the wild. The eggs of N. fragilis and N. pallida both have an exceptionally large pseudocapitulum; both eggs are illustrated.

Trachythorax maculicollis yunnanensis subsp. nov. from Yunnan, China is here decribed. Photographs of the adults and eggs as well as a key to female of the six known species from China are provided.
... Serangga ini dapat dengan mudah disalah artikan dengan daun-daun makanan yang menyebabkan co-inhabitant dan tidak jarang secara tidak sengaja memakan bagian abdomen mereka. Oleh karena hal itu, serangga ini berperilaku mudah panik saat terdapat spesies lain yang mengubah tatanan daun ataupun menyentuh mereka dan akan segera jatuh ke tanah dan menggerakkan badannya dengan gerakan meronta lalu membeku (Brock, 1995). ...

The Oriental stick insect genus Trachythorax Redtenbacher, 1908 is diagnosed, compared to closely related taxa, and reviewed based on examination of type material, collection material and photographic records, including citizen science sourced data. Each species is discussed and two new species are described from Vietnam: T. albomaculatus sp. nov. from Kon Chu Rang National Park in Central Vietnam and T. auranticollis sp. nov. from Dong Nai Biosphere Reserve in Southern Vietnam. Trachythorax yunnanensis Gao & Liang, 2021 stat. nov. is elevated to valid species, from status of subspecies of T. maculicollis (Westwood, 1848). Trachythorax illaesa (Redtenbacher, 1908) stat. rev. comb. nov. is reinstated as a valid species from previous status of junior synonym of T. maculicollis. As a result the genus Trachythorax now contains 15 species. New distribution records are provided for several species including new country records: Thailand and Myanmar for T. gohi Brock, 1999, Sri Lanka for T. illaesa Redtenbacher, 1908, Cambodia for T. maculicollis, India for T. sparaxes (Westwood, 1859) as well as Laos, Thailand, and Vietnam for T. yunnanensis. Distribution maps are provided for T. albomaculatus sp. nov., T. auranticollis sp. nov., T. gohi, T. maculicollis and T. yunnanensis. Egg morphology and egg deposition are described, discussed and illustrated for T. maculicollis, T. albomaculatus, T. yunnanensis and T. illaesa, the three latter species for the first time. Morphological adaptations of eggs are compared to those observed in other closely related genera such as Asceles Redtenbacher, 1908, Calvisia Stål, 1875, Korinnis Günther, 1932, Loxopsis Westwood, 1859, Marmessoidea Brunner von Wattenwyl, 1893, Sipyloidea Brunner von Wattenwyl, 1893 and Tagesoidea Redtenbacher, 1908, and egg parasitism is hypothesized as a potential evolutionary driver. Egg parasitism by Hymenoptera: Chalcidoidea is documented for the first time in nature for T. maculicollis and T. illaesa; it is hypothesised that several morphological characters are counteradaptations to the egg parasitism.

The southern African species of Bactrododema Stål, 1858, Palophus Westwood, 1859 (both Diapheromeridae: Palophinae) and Bactricia Kirby, 1896 (Diapheromeridae: Diapheromerinae), are reviewed. Bactrododema krugeri spec. nov. is described, while Bactrododema hecticum (Lichtenstein, 1796) comb. nov. is redescribed and discussed. Bactrododema brevitarsis Stål, 1876, Bactrododema aculiferum Kirby, 1902, Bactrododema lugardi Kirby, 1902, Palophus brevicornis Redtenbacher, 1908, Palophus holubi Redtenbacher, 1908, and Palophus transvaalensis Redtenbacher, 1908, are synonymized with Bactrododema tiaratum Stål, 1858. Phibalosoma calametum Bates, 1865, Hyrtacus carinatus Kirby, 1902, and Bactricia irregularis Brunner, 1907, are synonymized with Bactricia bituberculata (Schaum, 1857) stat. rev., which takes priority over Bactricia trophinus (Westwood, 1859). The genus Palophus is regarded as a synonym of the genus Bactrododema. Palophus titan Sjöstedt, 1913 is synonymized with Bactrododema hippotaurum (Karsch, 1896) comb. nov. Palophus rothschildi Bolivar, 1922 is synonymized with Bactrododema phillipsi (Kirby, 1896) comb. nov., and Palophus brongniarti Redtenbacher, 1908 is synonymized with Bactrododema episcopalis (Kirby, 1896) comb. nov. Keys to the adults of South African species are provided, eggs of two Bactrododema species are described, and the distribution of all southern African Bactrododema species mapped.
Chapter
The author proposes a revision of the stick insect species of the genus Thaumatobactron Günther, 1929. Four new species, T. bretoni n. sp., T. pulchracaelatura n. sp., T. pygminerme n. sp. and T. robillardi n. sp., are described. Egg of T. guentheri Hennemann & Conle, 1997, and females and egg of T. mayri Günther, 1930 are described for the first time. New data are provided and identification keys proposed for males, females and eggs.

This paper provides the commented list of the 824 type specimens of stick-insects of the collection of the Muséum national d’Histoire naturelle of Paris, corresponding to 319 species (including 287 currently valid species). The catalogue was made together with the digitalization and the databasing of the collection; it comes with an electronic document illustrating all of the specimens which were processed. Lectotypes are here designated for six species (Anisacantha albogeniculata Redtenbacher, 1906; Bacteria maroniensis Chopard, 1911; Gongylopus adiposus Brunner von Wattenwyl, 1907; Gratidia nimbana Chopard, 1955; Parectatosoma mocquerysi Finot, 1898 Tropidoderus exiguus Redtenbacher, 1908), and Oxyartes spinulosus Redtenbacher, 1908 is restored as a valid species.

At the moment, the taxonomy of the stick-insect Ramulus nematodes (de Haan, 1842) is confused, like other members of this genus or close to it. The distribution and biology of this species in rearing are dealt with first and foremost.
