( NHMB, ZKDC).   Description. Male( holotype). Body length 3.3 mm. Identical with  N. suturaliferin most external and male characters (see below), differing only by detailed morphology of sternum VII ( Fig. 37) and aedeagus ( Figs. 38, 39).  Female(see Remarks). Externally differing from male by simply rounded elytral apices. Variation.Body length (J ♀) 3.1–3.3 mm.   Differential diagnosis.  Notoxus sodalis sp. nov.is undoubtedly very close to  N. suturalifer, as suggested by the similarity of the male characters. It differs from the latter species as follows: postero-lateral sides of male sternum VII simple (lacking distinct submarginal edges; cf. Figs. 37 versus40), parameres of aedeagus with rather rounded apex and slight subapical lateral denticle in dorsal view, wider in basal half and rather rounded (not produced) at place of dorsal narrowing in lateral view (cf. Figs. 38, 39 versus42, 43).   Etymology.From the Latin  sodalis(companion, associate); named in reference to the overall similarity with the sympatric  Notoxus suturalifer. Noun in apposition.   Distribution. Laos.   Remarks.The specimens of  N. sodalis sp. nov.were collected in Pak Beng together with numerous specimens of  N. suturalifer(see above).As I failed to find any substantial differences between females taken at this locality (including shape of styli), only males of  N. sodalis sp. nov.were included in the typeseries. The six femaleslisted above under additional material are tentatively associated with this species by their smaller size, and more extensive dark markings of the elytra. 2001-05-18 2001-05-27 2001-05-18 PAK, BENG, JIRI, KOLIBAC, NHMB Laos 450 LAOS 32 659 1 holotype [397,906,1148,1173] 2001-05-18 2001-05-27 2001-05-18 NHMB, ZKDC Laos 450 LAOS 32 659 1 paratype 2003-05-04 2003-05-08 2003-05-04 MUANG, PAKBENG, ZKDC O.
