Methods 
Measurements were taken using a stereo microscope with 
an ocular micrometer. Body length was measured from apex 
of labrum to apex of elytra. Body lengths, therefore, may 
slightly differ from those specified by other authors. Length 
of pronotum was measured from mid of apex to the most 
advanced part of base. Length of elytra was measured from 
the most advanced part of humerus to the very apex. 
In the taxonomic survey standard methods are used. The 
male genitalia were removed from a specimen after being 
relaxed overnight in a moisturizing jar, then briefly cleared 
in hot KOH. The habitus photograph was manipulated 
using SPOT Advanced for Windows 3.5 and Corel Photo 
Paint 11. 
The male holotype and one female paratype of the new 
species are located in the Australian Museum, Sydney 
(AMS), one female paratype is located in the working 
collection of the author at Zoologische Staatssammlung, 
Miinchen (CBM).

Diagnosis. Small, compact, dorsally convex species, 
characterized by exceptionally coarse punctation of the upper 
surface of the pronotum and the elytral striae. Distinguished 
from the only similar species, Mecyclothorax punctatus 
(Sloane), by shorter and more oviform elytra, much more 
abbreviated elytra striae, and far less dense punctation of 
the pronotum. 
Description. Measurements. Fength: 3.0-3.25 mm; width: 
1.2-1.4 mm; ratios: width/length of pronotum: 1.26; width 
base/apex of pronotum: 1.13-1.16; width pronotum/head: 
1.41-1.44; length/width of elytra: 1.27-1.33; width elytra/ 
pronotum: 1.32-1.40. 
Colour. Rusty red, centre of head, pronotum, and disk of 
elytra darker, piceous to almost blackish, but dark colouration 
of elytra very ill delimited. Suture, base, and margins of elytra 
reddish, antennae reddish, mouth parts and legs dirty yellow. 
Fower surface of head, prothorax, and middle of abdomen 
piceous, rest reddish. 
Fig. 1. Mecyclothorax moorei n.sp., female paratype, habitus. Body 
length: 3.25 mm. 
Head. Considerably narrower than pronotum. Eyes 
laterally projected, orbits short, c. Vg of length of eye, 
forming a distinct angle with the lateral part of the head. Eyes 
separated from frons by a narrow furrow. Frontal furrows 
very deep, irregularly sinuate, running from clypeal seta, 
then suddenly turned out towards the eye, ended at anterior 
supraorbital seta. Centre of frons and lateral parts outside 
of frontal furrows convex. Clypeal suture deep, clypeus 
bisetose, punctures large and deep. Fabrum anteriorly very 
slightly concave, six-setose. Mandibles of moderate size, 
at apex suddenly incurved. Seta in outer scrobe elongate. 
Mentum with wide, obtuse, triangular tooth. Two mental 
setae and four gular setae present, all setae very elongate. 
Glossa truncate at apex, rather narrow, bisetose, paraglossae 
membranous, far surpassing glossa. Facinia elongate, 
sparsely spinose at inner margin. Terminal palpomeres of
