Recentstudies by Pawe³ JA£OSZYÑSKI (2007a,b,c; 2008a,c) and JA£OSZYÑSKI & NOMURA (2008)have resulted in important changes in the systematics of the tribe Cephenniini.Chelonoidum Strand, 1935 and Coatesia Lea, 1915 have been synonymized with Ce-phennodes (JA£OSZYÑSKI, 2007; 2008). After these changes the genus is represented inthe Oriental region by 84 species.Only six species of Cephennodes are known to occur in Thailand: C. falcipenis, C.frontocarinatus, C. inthanonensis, C. multisaetosus, C. oblongopunctatus, C. praemorsus andC. rhinoceros (all described by JA£OSZYÑSKI & NOMURA, 2008). Examination of the newmaterial from Thailand provided another new species of Cephennodes which clearlydiffers from all other members of the genus in a unique shape of the aedeagus. Freeparameres and the ventral orifice of the aedeagus located near the base of the me-dian lobe placed this new species in the nominotypical subgenus.NAT. CROAT. VOL. 18 No 2 263–266 ZAGREB December 31, 2009Croatian Natural History Museum, Demetrova 1, Zagreb, CroatiaThere are several species groups recognized currently in Cephennodes (JA£OSZYÑSKI,2007a,b) but the external morphology and the aedeagus of this new species doesnot fit any of them.MATERIAL AND METHODSThe measurements are as follows: body length is a sum of lengths of the head,pronotum and elytra measured separately; length of head was measured from a hy-pothetical line joining posterior margins of eyes to anterior margin of frontoclypealarea; width of head is maximum including eyes; length of antennae was measuredin ventral view; length of pronotum was measured along midline; width of prono-tum is maximum; length of elytra was measured along suture, from a hypotheticalline joining the humeral denticles to the apex; width of elytra is the maximum com-bined width; elytral index is length divided by combined width; length of aedeaguswas measured from base to apex of dorsal plate.The type material is deposited in the private collection of the author, Ni{, Serbia(PCMS).RESULTSCephennodes (Cephennodes) vegrandis n. sp.(Figs. 1–2)Diagnosis. This species has the following combination of characters: body smalland moderately convex; punctures on vertex near supra-antennal tubercles wellmarked; pronotum with moderately broad lateral margins, lateral carina stronglyraised and well separated from margin; aedeagus variant of simonis-type, with mo-derately long and very asymmetrical median lobe, with small subtriangular apicalpart; in lateral view apical projection very broad, flattened, with bifurcate apex;parameres free and distinctly asymmetrical, with pair of apical/subapical setae.Etymology.The name »vegrandis« (Latin »small, tiny«) refers to a small body of this species.Type material.Holotype (a): white printed label: »Thailand, Chumphon prov., Pha To env., 9''48'/98''47', 14–21.

Puncturation of frons and vertex very fine, sparse, shallow, central parts al-most impunctate; punctures of vertex near supra-antennal tubercles well marked,dense and deep; setation moderately long, suberect.

Puncturation on cen-tral part of disc fine and dense; punctures shallow, distance between puncturesequal to 0.5–1.2 times of their diameters; area near basal pits and lateral marginbears very small granules.
