Abstract AnewspeciesofthelampyridgenusLamellipalpusisdescribedfrom
MyanmarandillustratedunderthenameofL.unicolor.
Introduction
ThegenusLamellipalpuswasestablishedbyM6JA>@(1921)forEugeusisnigripen-
nisP6H8D:,1887,from“Burmah”,andcontainssixspeciesdistributedfromVietnamto
India. ThegenusLamellipalpushasbeenregardedasamemberofthefamily Drilidae,
and was inventoried twice as above family by OA>K>:G (1910) and W>IIB:G (1944).
In 2009, BG6C8J88> and G:>H:G (2009) revised the genus, recognized 12 species
including7newspeciesand1newsubspecies,andinaddition,providedakeytoallthe
taxa including the new ones.
In this paper, I have provisionally regarded the genus Lamellipalpus as an inde-
pendentgenusofthefamilyLampyridae,byfollowingtheopinionofW>IIB:G(1979),
L6LG:C8:andN:LIDC(1995)andBG6C8J88>andG:>H:G(2009). Adultmalesof
this genus were remarkably characterized by the extraordinarily expanded terminal
segments of both maxillary and labial palpi as in those of the genus Lamellipalpodes
(M6JA>@, 1921; W>IIB:G, 1979; 1995; K6L6H=>B6, 2007).
In2001,IwasabletoobtainfromMyanmarspecimensofthegenusLamellipalpus.
Afteracarefulexamination,onlyonespecieswasrecognizedasbeingnewtoscience.It
will be described and illustrated in this paper.
Material and Methods
The material and methods employed are the same as those noted in K6L6H=>B6
(2007). The abbreviations used herein are as follows: BL(cid:2)length of body, from
anterior margin of frons to elytral apices; HW(cid:2)maximum width of head, including
eyes; PL(cid:2)length of pronotum, along mid-line; PW(cid:2)maximum width of pronotum,
across basal angles; EL(cid:2)length of elytra; EW maximum width of elytra; EHW(cid:2)
humeral width of elytra; HTL(cid:2)length of hind tibiae; NSMT(cid:2)National Museum of
Nature and Science, Tokyo. The symbols “/” in the data of holotype labels mean
separate lines.
