Type locality. Laos, Hua Phan Prov., 25 km SE Vieng Xai, Ban Kangpabong env.
Type material. 3 specimens — Holotype ɗ ( NMPC), labelled: “ LAOS - NE; HUA PHAN prov.; / 25 km SE Vieng Xai (by road); / BAN KANGPABONG env.; / 20°19’N 104°25’E; / J. Bezdĕk leg.; 14–18.v.2001 [printed]”. Paratypes: 2ɗɗ (nos. 1–2), “LAOS-NE, Hua Phan prov., / 20°19’N 104°25’E, 25km SE / VIENG XAI (by road), / Ban Kangpabong env., / 14–18.v.2001,D.Hauck leg. [printed]” ( NHMW, NMPC).
Additional material studied. 4 specimens — LAOS: 3ɗɗ, Boli Kham Xai prov., 8 km NE Ban Nape, 18°21’N 105°08’E, ~ 600m, 1–18.v.2001, Vít Kubáň leg. ( NMPC); 1ɗ, same label data, but L. Dembický leg. ( NMPC).
Description. Habitus elongate, fusiform. Body colouring blackish. Pale part of setation consists of recumbent yellowish setae forming typical ocellations on pronotum, elytra and abdominal sternites, where setae are darker and sparser (Fig. 69).
Measurements. Males: 23–28 mm (holotype 24 mm).
Head punctation consists of irregularly distributed coarse setigerous punctures. Antenna robust, last antennomere ca. 1.88–2.00 times as long as wide ( Fig. 47 View FIGURES 35 – 50 ), its ventral side smooth with numerous small tubercles.
Pronotum largely transverse, ca. 2.21–2.39 times as wide as long, its sides almost regularly rounded. The disc with two rounded shallow depressions. Punctation consists of moderately large and sparse setigerous punctures on the disc, which become coarser and denser laterally.
Elytra with numerous longitudinal rows of large setigerous punctures, and very fine interstitial punctures.
Ventral part with fine punctures, which are sparse medially and become larger and denser laterally. Last abdominal ventrite laterally regularly rounded to apex.
Male. Aedeagus with phallobase longer than parameres. Parameres complex, widened apically. Subbasal parameral hook developed, but subapical hook absent. Medio-ventral parameral process, unique for the species complex is short and slightly hooked. Median lobe broadly lanceolate ( Fig. 31 View FIGURES 27 – 34 ).
Female. Unknown.
Remarks. The specimens from “Ban Nape” (Fig. 70) agree well in the shape of the aedeagus with typical specimens, however their habitus is almost the same as E. kubani sp. nov., which occurs at the same locality. As I am not able to resolve whether this is intraspecific variability or a different taxon, I did not designate these specimens as paratypes.
Differential diagnosis. Based on the shape of the aedeagus, E. janbezdeki sp. nov. is closely related to E. milleri from Vietnam. Both species can only be distinguished by the male genitalia. E. janbezdeki sp. nov. has the parameres with medio-ventral process short and slightly curved, and the median lobe is broadly lanceolate, whereas in E. milleri the parameral medio-ventral process is long and acute, and the median lobe is slender and subparallel.
Collection circumstances. The type material was collected at light. Specimens from Ban Nape were swept from a tree crown near a stream in primary forest (V. Kubáň pers. comm., 2002).
Distribution. So far known from only two localities in north-eastern, and central Laos respectively.
Etymology. The new species is dedicated to its collector, my friend Jan Bezdĕk (Brno, Czech Republic), a specialist on Chrysomelidae .
