- <p><b><i>Physoderes</i> Westwood, 1845</b></p><p>Figs 8–9, 13–20; Appendix</p><p><b>Diagnosis</b></p><p>This genus is recognized among other genera of Physoderinae by the scape reaching the apex of the clypeus, the parascutellar lobe being rounded and skewed towards the median, the males having an enlarged anterior pronotal lobe, wider than or equal to the width of the posterior lobe (except in <i>P. nigripennis</i> sp. nov., <i>P. ractepilosa</i> sp. nov. and <i>P. muluensis</i> sp. nov.), the median pronotal depression not being contiguous with the transverse sulcus (males) and by males having a membranous ductifer. This genus is most similar to <i>Epiroderoides</i> Villiers, 1962, but can be differentiated from it based on the anterior pronotal shape in males and the shape of the parascutellar lobes.</p><p><b>Type species</b></p><p><i>Physoderes notata</i> Westwood, 1845, by monotypy.</p><p><b>Redescription</b></p><p><b>Male</b></p><p>BODY LENGTH. Size variable, total length 6.08–11.03 mm (Appendix).</p><p>COLORATION (Figs 14–18). Variable, from straw-colored to dark brown. Head, anterior pronotal ridges, posterior pronotal lobe, legs and corium of similar lighter coloration, anterior pronotal lobe, scutellum and claval region with darker coloration.</p><p>VESTITURE. Sparsely to densely setose with curved, fine or erect setae, with pair of long, straight setae on posterior margin of postocular lobe (except in <i>P. nigripennis</i> sp. nov. and <i>P. nigroalbus</i>).</p><p>HEAD. Elongate or short, conical; maxillary plate most often rounded apically; scape never distinctly surpassing apex of clypeus; eye hemispherical in dorsal view except in <i>P. nigripennis</i> sp. nov. and <i>P. tricolor</i> sp. nov., less than 1/5 length of head and never reaching ventral margin of head in lateral view; ocelli present; height of anteocular lobe shorter than postocular lobe except in <i>P. anamalaiensis</i> sp. nov. and <i>P. mysorensis</i> sp. nov.</p><p>THORAX. Shape of antero-lateral paired pronotal projection variable; surface of anterior pronotal lobe most often with low ridges; median pronotal depression not contiguous with transverse sulcus except in species without enlarged anterior pronotum; paramedian carina variable; posterior lobe medially rugose; length of anterior pronotal lobe variable, wider and higher than or equal to posterior lobe except in <i>P. nigripennis</i> sp. nov., <i>P. ractepilosa</i> sp. nov. and <i>P. muluensis</i> sp. nov.; parascutellar lobe rounded and sometimes skewed towards median, except in <i>P. brevipennis</i> sp. nov.; scutellum rounded triangular except in <i>P. azrael</i> and <i>P. curculionis</i>, length of scutellar process and shape of apex variable; mesosternite with median irregular tuberculated protrusion between fore and mid coxae.</p><p>HEMELYTRON. Macropterous, never surpassing tip of abdomen.</p><p>LEGS. Fore femur distinctly incrassate, tarsi three-segmented.</p><p>ABDOMEN. Elongate ovoid except in <i>P. brevipennis</i> sp. nov. and <i>P. curculionis</i>, with rounded terminal margin except in <i>P. ractepilosa</i> sp. nov.; shape of connexival margin variable, posterior margin only slightly elevated in <i>P. nigripennis</i> sp. nov.</p><p>GENITALIA. Variable (see species descriptions for details).</p><p><b>Female</b></p><p>Females with anterior pronotal lobe narrower and lower than posterior lobe, with median pronotal depression contiguous with transverse depression.</p><p><b>Ecology</b></p><p>Species from this genus are found in a variety of living and dead plant materials and in the undergrowth. Specimens have been collected from pitfall traps and carrion traps and have been found at up to 1200 m elevation.</p><p><b>Distribution</b></p><p>This genus is the most widespread of the subfamily, and species distributions cover the entire known range of Physoderinae in the Old World except in the Afrotropics. Species can be found in Madagascar, the Indian subcontinent, peninsular Malaysia, Sumatra, Java, Borneo, the Philippine archipelago, Sulawesi, Papua New Guinea, the Solomon Islands and the Fiji Islands.</p><p><b>Remarks</b></p><p><i>Physoderes notata</i> is the type species of <i>Physoderes</i> by monotypy and the clade that includes <i>P. notata</i> and <i>P. nigripennis</i> sp. nov. derived from the phylogenetic analysis above is recognized as the revised <i>Physoderes</i>.</p><p><b>Key to species of <i>Physoderes</i></b></p><p>1.
