M. Peterson 
(possibly unique in genus) when anterior dorsal 
elytral spines absent; dorsally with a pronounced, 
dense scale pattern of pearl-white, pink-brown and 
blue patches and alternating pearl-white and black- 
bronze vittae; ovipositor with a flattened blade-like 
apex. Most like C. albisparsus Pascoe, C. cicatricosus 
Pascoe and C. marginispinis Pascoe but differs from 
these by lacking small forwardly directed tubercles 
at elytral base and possessing pink-brown and blue 
scales and smaller anterior dorsal spines (<56% of 
LPS vs >59% of same) set more caudad on elytra 
(ASI: 50-58 vs 44-54). 
Description 
TL: 8.8 - 12.1 mm. Body, including lateral post- 
humeral spines, black; antennae, legs and dorsal 
elytral spines red to dark red. Scales dense 
throughout, dorsally forming a constant pattern of 
alternating black-bronze and brilliant pearl-white 
vittae and pearl-white, pink-brown and blue 
patches on a black background (Figure 1); no 
powdery exudate present. Setae hair-like, con¬ 
spicuous. Head with frons flat, without a median 
cariniform elevation; admedian and lateral frontal 
carinae present, both pairs short, sometimes 
obscured by scales, strongly converging anteriorly; 
frons with numerous conspicuous setae; eyes 
convex, about 1.3 X as long as broad. Rostrum 1-1.2 
X as long as broad, scarcely widening apically; 
median carina evenly and moderately raised for 
most of its length, slightly higher than frons and 
usually more or less parallel with latter in profile 
view (not arched); chin weak. Mentum with four 
setae. Antennae with length of funicle segments 1-3 
in ratio 2.8 : 1.5 :1 (mean, n=13). Prothorax weakly 
transverse (length to width ratio, 10 : 143-16.8), a 
little wider at base than apex; post-ocular lobes 
well developed, angulate. Scutellum smooth, 
covered in a few ovate scales. Elytra globose- 
acuminate (length to width ratio, 10 : 6.9-7.4), 
dorsally quadrispinate or occasionally bispinate 
when anterior dorsal elytral spines absent; LAS 0- 
55.6% (mean 29.5%, n=13) of LPS, with 3 values 
slightly less than 2 (0-40% vs 19.4—55.6%); ASI: 
50-56 in 3 (mean 53.8, n=8), 52-58 in 2 (mean 
55.3, n=4); LPS 17.1-35.8% (mean 26.1%, n=13) of 
AC, with little overlap between the values of the 
sexes (<J, 24.4-35.8% vs 2, 17.1-25.3%); PSI: 52-58 
in 3 (mean 56.3, n=9), 57-62 in 2 (mean 59.1, n=4); 
IPSB 35-39.3% (mean 36.7%, n=13) of TW; posteri¬ 
or dorsal elytral spines diverging, IPSA 118.2- 
155.6% (mean 137.1%, n=13) of IPSB, with 2 values 
slightly less than 3 (118.2-135.7% vs 125-155.6%); 
IAPSB 19.4-24.6% (mean 20.9%, n=12) of TW; post- 
humeral spine well developed with tip strongly 
reflexed caudad. Legs with femora moderately 
swollen; tibial teeth small; corbels moderately 
narrow, without scales and with 9-15 adventitious 
setae. Venter of 3 with post-coxal groove and bead¬ 
like granules on ventrite 1. 
Vestiture intraspecifically constant, with scale and 
setal coloration and configuration as follows: white 
scales (with pearly reflections) and black-bronze 
scales dense, imbricate-appressed; pink-brown 
scales (with coppery reflections) dense, imbricate- 
semi erect; blue scales sparse/tessellate-appressed; 
setae dark brown, prominent, hair-like, semi-erect 
to recumbent, scattered evenly over antennae, legs 
and body (including elytral spines). Underside 
throughout (including head) with white scales. 
Eyes encircled with white scales; dorsal remainder 
of head and rostrum with white scales except for 
narrow median vitta of bronze to black-bronze 
scales and some bronze scales behind eyes. 
Prothorax dorsally with moderately broad median 
vitta of white scales flanked by two slightly 
broader longitudinal admedian tracts of black- 
bronze scales which cover everything except the 
deeper grooves; these dark tracts each contain a 
small mid-lateral and baso-lateral patch of white 
and/or blue scales, as well as scattered blue scales 
at anterior margin which do not reach median 
vitta; sides with white scales. Elytra with a white 
sutural vitta covering width of interstria 1 and
