Type material

The new species is named after Anton Olegovich Kozlov, who sent and donated the specimens.


In Eurysthea there are only four species with elytra having two types of pubescence that include long, erect setae and shorter, lanceolate setae: E. antonkozlovi sp. nov.; E. barsevskisi sp. nov.; E. robertsi ; and E. squamifera . Eurysthea antonkozlovi sp. nov. differs from all of them by the head, prothorax and elytra black or reddish-black (reddish-brown in the others) and by the spine of the inner apex of the antennomere III longer, as long as half the length of antennomere IV (in the other species is shorter). It differs from E. squamifera and E. barsevskisi by the prothorax with lateral spines (absent in E. robertsi and E. squamifera ). It can be separated from E. robertsi and E. squamifera by the lanceolate setae on the elytra (squamiform in these species).

Eurysthea antonkozlovi sp. nov. is also similar to E. martinsi Fonseca-Gessner, 1990 , but differs as follows: body with lanceolate setae, mainly dorsally; spine of the inner apex of the antennomere III notably longer; upper eye lobes narrower, with 5–6 rows of ommatidia; elytral punctures finer and sparser; distal area of elytra with irregular yellowish-brown area. In E. martinsi the body has no lanceolate setae, the spine of the inner apex of the antennomere III is shorter (see Bezark 2016), the upper eye lobes are wider with 8 rows of ommatidia, the elytral punctures are coarser and denser (mainly on basal third), and the elytral apex has no yellowish-brown area.
