Synopsis of the Asian species in the genus Zarcosia Collado & Alonso-Zarazaga 1996 with new combinations and descriptions of fourteen new species Author Gompel, Nicolas text Zootaxa 2020 2020-08-26 4838 2 151 178 journal article 8744 10.11646/zootaxa.4838.2.1 761fcec7-c79d-4e80-bb2b-23cc9e78e0b6 1175-5326 4403783 0AD43D95-7508-466C-980F-CBEF38CA1198 Zarcosia palliditarsis (Pic, 1912) , comb. nov. ( Figures 1 ; 2t ; 4k ; 5 e–g) Hylophilus palliditarsis Pic, 1912: 274 ; Type: MNHN ( 1 male “ syntype ”); BMNH ( 2 male “co-types”) Xylophilus palliditarsis Pic, 1912 : Champion, 1915 Zarcosia palliditarsis (Pic, 1912) : unpublished combination in Grzymala, 2016 This species and Zarcosia lemairei n. sp. are remarkable among all Zarcosia species discussed in this work by the morphology of the male head ( Fig. 5 a–c, e–g). In both cases, the head capsule is carved dorsally and possesses a wavy brush of long yellow bristles. This sexually dimorphic trait is reminiscent of cephalic modification in some Scydmaenus species (Scydmanenidae), while these bristles are similar to the trichomes present in Paussinae Carabidae and other inquilines. Zarcosia palliditarsis (Pic, 1912) may very well be a junior synonym of Euglenus planipennis Motschulsky, 1863 , also from Sri Lanka . The type material of this species is presumably kept in St. Petersburg or in Moscow and I did not manage to locate it. It is not possible on the sole basis of Motschulsky’s description, 1863 to clarify the taxonomic status of this species. Type locality. Sri Lanka : Kandy . Distribution. Sri Lanka ( Figure 1 ). Material examined. Sri Lanka : Kandy ( G. E. Bryant ) VI.1908 ( 1 ♂ and 1 ♀ syntype , MNHN ; 2 ♂ co-types, 1 ♂ and 2 ♀ , BMNH ) .
