INTRODUCTION<br />

The buprestid genus Mi[*]-oac.n~aeode~-a was originally described by COBOS<br />

( 1966) as a subgenus for Acmaeodel-u (Mic.1-ocic.n~ueode~-a) 1ongic.ol-11i.s Cobos<br />

from eastern Afghanistan. Later <strong>the</strong> status <strong>of</strong> Mic.~-oac.n~ucode~-a was elevated to<br />

<strong>the</strong> generic rank by VOLKOVITSH ( 1986), and two subgenera, Mic.1-oat-n~aeodel-a<br />

(s. .st]-.) and M. (Squarnic.~-oac.n~aeode~-a) were separated.<br />

In terms <strong>of</strong> extant distribution and zoogeography, <strong>the</strong> species <strong>of</strong> Mic.1-oacmacodel-a<br />

arc from <strong>the</strong> Indo-Oriental region: M. (M.) 1ongico1-nis (type species)<br />

and M. (M.) ~7ittn1c.1-i Vol kovitsh are partly geographically sympatric in <strong>the</strong><br />

western Himalayas; M. (S.) helli (Kerremans) (type species) is from India and<br />

M. (S.) a]-ue~~sis ('l'hiry) is from Aru lsland and perhaps Borneo. Recenlly one<br />

more species, M. (S.) rncicg~-ego]-i Bellamy & Volkovitsh ( 1992) was described<br />

from Luzon Is., Philippines.<br />

The discovery <strong>of</strong> two new species, collected by Czech coleopterists in<br />

Thailand during 1991-92, has prompted a return to <strong>the</strong> taxonomy <strong>of</strong> this genus<br />

once again. The locality data is recorded herein as presented on <strong>the</strong> specimen<br />

labels. We are grateful to our colleague Ing. Vitezslav Kuban, Brno, Czech<br />

Republic for rhe loan <strong>of</strong> material for this study; his collection will be<br />

abbreviated VKBC.

Comments<br />

Microacmaeoder-a (S.) kuhani comes closest to M. (S.) aruensis, differing<br />

by <strong>the</strong> small body, lateral keel <strong>of</strong> pronotum entire, and sculpture <strong>of</strong> hypomera<br />

and abdomen markedly reticulate-rugose. From this last character it differs<br />

from all o<strong>the</strong>r species <strong>of</strong> M. (Squamicroacmaeodera). The four species <strong>of</strong> this<br />

taxon are contrasted in Table 1.<br />

Etymology<br />

This new species is obviously named for <strong>the</strong> collector <strong>of</strong> <strong>the</strong> unique type<br />

specimen, our friend and colleague Vita Kuban.<br />

TWO NEW SPECIES OF MICROACMAEODERA<br />

Comments<br />

Microacmaeodera (s. str.) thailandica differs from all o<strong>the</strong>rs <strong>of</strong> its<br />

congeners from M. (s. str.) by having <strong>the</strong> feebly elongate, ra<strong>the</strong>r broad body<br />

and relatively short antennae. With <strong>the</strong>se characters it bears a superficial<br />

resemblance to species <strong>of</strong> M. (Squamicroacmaeodera); however, it can be<br />

separated into <strong>the</strong> nominate subgenus by virtue <strong>of</strong> <strong>the</strong> punctate sculpture and<br />

setose vestiture. Moreover, <strong>the</strong> female antennae <strong>of</strong> M. (s. str.) thailandica are<br />

significantly longer than those <strong>of</strong> M. (Squamicroacmaeodera) species, which<br />

are characterized by an antenna1 length to eye height index varying from 1.32<br />

(M. kuhani) to 1.57 (M. macgregori); <strong>the</strong> female <strong>of</strong> M. aruensis was not<br />

studied. The three species <strong>of</strong> Microacmaeodera (s. str.) are contrasted in<br />
