03C087BC7D0DFF8DFD9DFEBD4A9C094A.taxon	discussion	Notes This is a common species in Japan, which can be captured at light (S. Makita, personal communication). Larvae can be collected under the bark of decaying oak wood (Hayashi 1975) and walnut trees, Juglans mandshurica var. sachalinensis. Nikitsky (1999) mentioned that antennomere XI of this species is ca 2.5 – 2.8 times as long as the width, whose data were followed by Hsiao (2015) and Hsiao et al. (2016). However, our examination shows that this species has a wider variation in the length of antennomere XI than previously documented.	en	Hsiao, Yun, Ondřej Konvička, Chiun-Cheng Ko (2018): The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae).

03C087BC7D0FFF8BFD94FDC24ACE0860.taxon	discussion	Remarks In the original description, Nikitsky (1999) provided as diagnostic character the presence of faint striae only in apical part and illustrated it. This character together with the posteriorly narrowed elytra has been used in Hsiao (2015) and Hsiao et al. (2016) as comparative information to distinguish S. formosana. However, in the course of this study we discovered that the elytral striae are variable, noticeable on the entire elytron or even indistinct in some specimens. Elytral striae of synchroids are vague and difficult to observe accurately if the specimen is dry and not dissected, consequently it is possible that the elytral striae of the holotype have not been not observed correctly. After examining a large number of specimens, the shape of the elytra appears proved to be variable as well (length ca 2.4 – 2.7 times width). Therefore, we eliminate both inappropriate characters from the diagnosis and re-diagnose the differences between the species (see the detail in diagnosis and key).	en	Hsiao, Yun, Ondřej Konvička, Chiun-Cheng Ko (2018): The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae).

03C087BC7D08FF89FD8DFEBD4A1B09EA.taxon	discussion	Notes Although this species was described as having elytral striae in the basal half of the elytron, we discovered that the elytral striae are noticeable on the entire elytron (Fig. 4 D) or indistinct in some specimens. Besides, elytral striae on each elytron vary from 4 – 7 traces in this species. On the other hand, we examined one specimen having narrower apical half of paramere than the holotype (Fig. 6 L). After examination of the external morphological characters and the median lobe of the aedeagus, and in consideration of the intraspecific variation of other synchroids, we herein conclude that it is conspecific with S. formosana.	en	Hsiao, Yun, Ondřej Konvička, Chiun-Cheng Ko (2018): The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae).

03C087BC7D0AFF87FD9FFEBD49630A2B.taxon	discussion	Notes In the original description, this species was mentioned as having striae only in the apical part of the elytral suture. However, we discovered extremely indistinct elytral striae on this specimen. Together with our analysis of this character, it is possible that the elytral striae of the type series are too faint to observe or this character varies from absent to indistinct within this species. On the other hand, although most of the characters are in accordance with the original description, the parameres of this specimen are different from the illustration given in Nikitsky (1999) by its distinctly widened lateral sides and narrower dorsal groove, which implies that it could belong to another taxon new to science. Considering the insufficient material, intraspecific variation within other species and geographic distribution, we herein regard this specimen as representing a variation of S. elongatula instead of giving it a new taxonomic status.	en	Hsiao, Yun, Ondřej Konvička, Chiun-Cheng Ko (2018): The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae).

03C087BC7D05FF85FDF5FD184F640952.taxon	discussion	Notes This species was described based on specimens from “ Perak, Sumatra ” (Fairmaire 1898); however, Nikitsky (1999) mentioned that only “ Perak ” was written on the label, and there is no locality in Sumatra called Perak; it is in Malaysia. During our study S. tenuipennis is newly recorded for Indonesia, based on two specimens from West Sumatra and South Kalimantan, respectively.	en	Hsiao, Yun, Ondřej Konvička, Chiun-Cheng Ko (2018): The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae).

Notes Two errata were present in the original description and are corrected as follows: (1) the ventral view of aedeagus was misplaced as dorsal view in figures 6 – 8; (2) transverse coxal diameter is 4.38 times width between fore coxae, rather than the width between fore coxae 4.38 times transverse coxa diameter.	en	Hsiao, Yun, Ondřej Konvička, Chiun-Cheng Ko (2018): The world fauna of Synchroidae Lacordaire, 1859 (Coleoptera, Tenebrionoidea, Synchroidae).
