Taxonomic notes relating to Glenea diversenotata Schwarzer and G. quadriguttata Pic (Coleoptera, Cerambycidae, Lamiinae)

Abstract Glenea diversenotata Schwarzer, 1925 is reinstated from a subspecies of Glenea tonkinea Aurivillius, 1925 to species level and Glenea neohumerosa Lin & Yang, 2011 is a new junior synonym. Some biological information on Glenea diversenotata is recorded for the first time, including pictures of the larva and pupa. Glenea quadriguttata Pic, 1926 is reinstated from a subspecies of Glenea lacteomaculata Schwarzer, 1925 to species level. Lectotypes for Glenea lacteomaculata and Glenea quadriguttata are designated. A modified key to the related species is presented.


Introduction
Glenea diversenotata Schwarzer, 1925 andG. quadriguttata Pic, 1926 were described from Taiwan and N. Vietnam, respectively. Later, the former was downgraded as a subspecies of G. tonkinea Aurivillius, 1925 and the latter as a subspecies of G. lacteomaculata Schwarzer, 1925by Breuning (1956. Comparison to the type materials, however, reveals that each of them should be reinstated to species level from subspecies level. We therefore present the new taxonomic decisions, justifications, and full synonymies below.
Remarks. Breuning (1956) treated G. diversenotata Schwarzer as a subspecies of G. tonkinea Aurivillius, 1925. The first author examined a photograph of the holotype of G. diversenotata Schwarzer, 1925 (taken by Nobuo Ohbayashi, Japan) and a photograph of a live specimen matching it from Taiwan (taken by Yu-Long Lin, Taiwan). Our study of these additional materials necessitates a new synonymy of G. neohumerosa Lin & Yang, 2011. We can find no morphological differences to maintain them as separate species. Likewise, our examination of the types of G. diversenotata and G. tonkinea leads us to review the taxonomic position of them since Breuning (1956) that G. diversenotata is a subspecies of G. tonkinea. We can find no morphological support for that treatment by Breuning. They are easily separated from each other by the following characters -Glenea tonkinea: vertex and occiput of the head with two separate, longitudinal vittae of white pubescence; white elytral maculae more slender and transverse; outer, basal, white, elytral maculae anterolaterally positioned relative to the larger, basal, sutural maculae; outer apical spine of Remarks. The record from Taiwan (Nakamura, Makihara, Saito, 1992;Hua 2002;Löbl and Smetana 2010;Nakamura et al. 2014) is doubtful. This taxon was not mentioned in the four volumes of Taiwanese fauna book (Yu and Nara 1988;Yu, Nara and Chu 2002;Chou 2004Chou , 2008. Distribution. China (Guangdong, Hainan, Guangxi, Taiwan?); Vietnam (Tonkin), Myanmar.

Glenea lacteomaculata Schwarzer, 1925, lectotype designation
Glenea lacteomaculata Schwarzer, 1925: 151 fig. 10. Glenea (G.) lacteomaculata; Nakamura, Makihara, Saito, 1992: 105;Nakamura et al. 2014: 174. Glenea lacteomaculata;Hua 2002: 210;Hua et al. 2009, 216, 358, pl Remarks. Lin and Yang (2011) were unable to define G. lacteomaculata Schwarzer, 1925. Subsequently, the first author examined a photograph of a syntype of G. lacteomaculata (taken by Nobuo Ohbayashi, Japan). Comparing that photograph with another of G. quadriguttata Pic, 1926, it is possible to conclude that the latter must be elevated to species. Hua (2002) indexed Taiwan and Guangxi and this was followed by Löbl and Smetana (2010). However, the specimens from Guangxi should be G. quadriguttata Pic, 1926 (Lin andYang 2011) and only Taiwan was the known locality of G. lacteomaculata Schwarzer, 1925. Distribution. China: Taiwan. Lectotype designation. According to the original description (Schwarzer 1925), there were multiple type specimens. The syntypes were deposited in SDEI and SMF. In order to fix the species concept and ensure universal and consistent interpretation of this species, we designate the female specimen in SDEI as the lectotype (Fig. 10a,  b), the female in SMF (Fig. 11a, b) and another one with same collecting data to the lectotype (Behne and Gaedike 2013) as the paralectotypes of G. lacteomaculata Schwarzer, 1925. Though the female in SMF is in better condition than the female with antennae mostly lost in SDEI, we pick up the SDEI one as lectotype according to ICZN Recommendation 74D. The majority of Schwarzer's types collected by Hans Sauter is contained in SDEI (listed by Behne and Gaedike 2013;Stephan Blank and Junsuke Yamasako, personal communication in November, 2015). The lectotype has the following labels: "Sokutsu/ Formosa/ H. Sauter 1912" printed, "7.VI." printed, "Glenea lacteomaculata / Cotype! Schwarzer" handwritten, "Syntypus" printed on red label, "DEI Coleoptera # 200572" printed on white label. And a lectotype label will be added by the managers in SDEI after this paper.
Distribution. China (Guangxi, Yunnan); Vietnam (Tonkin). Lectotype designation. The original description does not allow to know the number of specimens used by Pic (1926). In order to fix the species concept and ensure universal and consistent interpretation of this species, we designate the female specimen with Pic's handwriting labels as the lectotype (Fig. 12a, b), and the first author did not find another syntype to be paralectotype when she worked in MNHN in 2007MNHN in -2008. The lectotype has the following labels: "Ha Djang/ (Tonkin)" handwritten, "G. quadriguttata Pic" handwritten, "type" handwritten on yellow label, "Breuning valiv" handwritten, "TYPE" printed on pink red label. And a lectotype label will be added by the managers in MNHN after this paper.
