03F1CE55FFA6FF94FDC2FB7EFD9755A9.taxon	discussion	Comparative notes Because the males of other species of Xenorhyncocoris are unknown, the following comparisons are based on females. Xenorhyncocoris attractivus sp. nov. resembles X. caraboides in the dorsally curved labial segment II, but it can be easily distinguished from the latter by: the much smaller size (body length 33.4 mm in X. attractivus sp. nov. vs about 37 mm in X. caraboides); head 1.8 times as long as pronotum (vs 2.2 times as long as pronotum in X. caraboides); anteocular part 1.45 times as long as postocular part (vs 1.3 times as long as postocular in X. caraboides); labial segment II reaching posterior margin of eye, 1.65 times as long as segment III (vs distinctly surpassing posterior margin of eye, 1.9 times as long as segment III in X. caraboides); apex of prosternum reaching middle of mid coxae (vs almost reaching posterior margins of mid coxal cavities in X. caraboides). Xenorhyncocoris attractivus sp. nov. can be separated from X. schoenitzeri by: anteocular part 1.45 times as long as postocular part (vs 1.7 times in X. schoenitzeri); labial segment II dorsally curved, segment III moderately inflated (vs labial segment II straight, apically bulbous, segment III strongly inflated in X. schoenitzeri); pronotum 1.15 times as broad as its length (vs width of pronotum equal to its length in X. schoenitzeri); posterior pronotal lobe 1.15 times as broad as width of anterior lobe (vs posterior lobe as broad as anterior lobe in X. schoenitzeri). Xenorhyncocoris attractivus sp. nov. is most similar to X. princeps in the shape of the head and the moderately inflated labial segment III. The new species differs from the latter by the following characters: labial segment II dorsally curved, 1.65 times as long as segment III (vs labial segment II straight, apical ⅔ of ventral surface slightly thickened, 1.9 times as long as segment III in X. princeps); pronotum 1.15 times as broad as its length (vs width of pronotum equal to its length in X. princeps); posterior pronotal lobe 1.15 times as broad as width of anterior lobe (vs posterior lobe as broad as anterior lobe in X. princeps); apex of prosternum reaching middle of mid coxae (vs reaching anterior margins of mid coxal cavities in X. princeps). Moreover, several additional characters can also distinguish X. attractivus sp. nov. from its congeners: the blackish brown body color (vs brown in other species); the ~ 90 ° erected scutellum (vs ~ 45 ° suberected scutellum in other species); apex of fore wing reaching middle of scutellum (vs surpassing middle but not reaching apex of scutellum in other species). Species of the genus Xenorhyncocoris can be distinguished with the key above.	en	Chen, Zhuo, Liu, Yingqi, Cai, Wanzhi (2021): Taxonomic review of Xenorhyncocoris Miller (Heteroptera: Reduviidae: Ectrichodiinae), with description of X. attractivus sp. nov. and notes on sexual dimorphism of the genus.

03F1CE55FFB0FF88FE43FCD1FD3C5438.taxon	discussion	Remarks Putshkov & Bérenger (1999) described X. schoenitzeri based on a single female specimen from western Sumatra. This specimen is now deposited in the Zoologische Staatssammlung München, Munich, Germany (ZSM). Xenorhyncocoris schoenitzeri is highly recognizable due to its straight and apically bulbous labial segment II, and also by the combination of other characters mentioned in the diagnosis. This species was relatively well documented in its original description and illustrations. Photographs of habitus of the holotype (Figs 57 – 59) are provided herein to facilitate the recognization of this species. Some diagnostic characters mentioned by Putshkov & Bérenger (1999) are discussed below.	en	Chen, Zhuo, Liu, Yingqi, Cai, Wanzhi (2021): Taxonomic review of Xenorhyncocoris Miller (Heteroptera: Reduviidae: Ectrichodiinae), with description of X. attractivus sp. nov. and notes on sexual dimorphism of the genus.
