A second species of the enigmatic lampyrid genus
The genus
The methodology and morphological terminology used herein follows that of Jeng et al. (2007). The body length (BL) is the sum of the pronotal and elytral lengths (PL and EL, respectively) plus length of those exposed portions of the head from the pronotum; while body width is considered as twice the elytral width (BW = 2EW). Pronotal width was abbreviated as PW. The nomenclature of the hind wing venation follows that of Kukalová-Peck and Lawrence (2004) rather than that of Kukalová-Peck and Lawrence (1993) which was employed by Jeng et al. (2007). In reporting label data the symbol “/” indicates separate lines on a single labe, while “//” denotes material located on separate labels.
The original diagnosis of the genus provided by Jeng et al. (2007) was based strictly on

4 ♂♂, with identical data as holotype; 1 ♂, with identical data except collected on 18 May 1998; 1 ♂, with identical data as holotype except collected at 600m above sea level on 7–14 April 1998 by K. Long; 1 ♂, with identical data as holotype except collected on 5 May 1998 by K. Long. All deposited in the AMNH.

The species has several diagnosable characters separating it from the type species: 1) body size slightly larger (6.2–8.2 vs. 6.0 mm); 2) more vivid light brown-tan bicoloration (
Male. BL: 6.2–8.2 mm; BW: 2.7–3.4 mm; PW/PL = 1.5–1.6; EL/ EW = 3.6–3.8; EL/PL = 3.8–4.4; BW/PW = 1.4–1.5. The species is very similar to the type species in general morphology except the aforementioned differences, and need not be repeated here. As described for
The specific epithet refers to the two-toned coloration which is more vivid in the new species than in
According to the available collection data, males appear at least from April to May.
