With nearly a flat prosternal process (i.e. without transverse depression or longitudinal keel), the new species is similar and probably related to  P. taprobanicus from Sri Lanka; however, it differs from the latter species in the shape of male genitalia: the apex of median lobe is not bent as in  P. taprobanicus and the curvature of the median lobe of  P. bistroemi sp. nov. is shallower. The parameres of  P. bistroemi sp. nov. are abruptly narrowed and rounded at their apex while in  P. taprobanicus those are gradually narrowed. The setae of the parameres are present in the apical half in  P. bistroemi sp. nov. while in  P. taprobanicus these are restricted to the apex. Further, the spermathecal spine in  P. bistroemi sp. nov. is longer than the other three Indian species, and not curved like that in  P. nilssoni sp. nov.</p><p>Etymology.</p><p>The species is named in the honour of Prof. Olof Bistrӧm (Helsinki, Finland) for his significant contribution to the taxonomy of  Dytiscidae, including the genus  Peschetius .

Body length 2.60-3.15 mm (holotype: 2.75 mm), and maximum width 1.64-1.74 mm (holotype: 1.64 mm). See also Supplementary file 4.</p><p>Variability.</p><p>The species slightly varies in body size and width. The shape of sub-basal yellow spot on elytra varies within species.</p><p>Differential diagnosis.</p><p>With the black head, and the prosternal process convex with a short apical keel, and the general shape of the male genitalia,  Peschetius nilssoni sp. nov. is very similar and undoubtedly closely related to  P. toxophorus . This fact is confirmed also by the raw genetic distance as measured by the cox1 gene, which is 2.7-3.3%-the least differentiated within Indian  Peschetius . The two species can be easily recognised based on the shape of the testaceous premedian transverse band on elytra, which is always interrupted between elytral costae in  P. nilssoni sp. nov. forming lateral longitudinal spot (Fig. 5Ba) and discal transverse spot (Fig. 5Bb) while the band is always uninterrupted in  P. toxophorus (Fig. 5Da). Additionally, the body shape of  P. nilssoni sp. nov. is more elongate and narrower (Fig. 5B), while it is broader in  P. toxophorus (Fig. 5D). These differences in body shape were also confirmed with the multivariate morphometric analysis (Fig. 3). Further, the median lobe of  P. nilssoni sp. nov. is gently and evenly curved (Fig. 6Ba), while that of  P. toxophorus is more strongly and unevenly curved (Fig. 6Da). Parameres are gradually narrowing to their apex in  P. nilssoni sp. nov., (Fig. 6Bbx) but they are distinctly tapered subapically in  P. toxophorus (Fig. 6Dbx). Finally, the spermathecal spine in  P. nilssoni sp. nov. (Fig. 8Ba) is curved unlike compared to other Indian species.</p><p>Etymology.</p><p>The new species is dedicated to Dr. Anders N.

Pronotum testaceous with bilobed black band near posterior margin extending to posterior corners. Elytron blackish with typical testaceous markings consisting of two subbasal spots, premedian and postmedian transverse bands and preapical spot. Punctation of head dense, distance between punctures smaller than puncture diameter. Punctures fine on clypeus, become progressively larger posteriorly on frons, occipital part posterior to eyes impunctate. Setiferous punctures present in shallow but distinct fronto-clypeal depressions and as a row along inner margin of eyes. Reticulation consisting of polygonal meshes, impunctate occipital part coarsely microreticulate. Pronotal disc with posterior depression less prominent but distinguishable. Punctation dense, distances between punctures smaller than puncture diameter. Punctures setiferous, finer on disc, becoming coarser on margin and sides. Surface between punctures microreticulate with well impressed, polygonal meshes. Elytra broadest at midlength, keels prominent. Punctation dense, distance between punctures smaller than puncture diameter. Punctures finer along suture, costae and lateral margin, coarser on disc. Surface between punctures microreticulate, reticulation consisting of polygonal meshes. Prosternal process elongate, narrowed at apex, apically keeled, tuberculate in males. Abdomen with five ventrites (V1 to V5); V1 with 7-9 macropunctures arranged in one row while V2 with 4-7 macropunctures on each side, arranged in two rows randomly; punctation on V2 to V5 consisting of setiferous punctures; lateral depression on V3 to V5 prominent; reticulation of V2 to V5 consists of polygonal meshes. Ventral surface with large setiferous punctures. Median lobe strongly curved, tapering apically, apex pointed; with a basal process (Fig. 6Da). Parameres with long setae in apical 3/5th, apex rounded, inner margin strongly bisinuate (Fig. 6Db). Spermatheca as in (Fig. 8D)-spermathecal spine straight, short and broad.</p><p>Collection circumstances.</p><p>The species was found inhabiting pools, ponds, tanks, reservoirs and slow flowing streams.
