Frischianus rufulus (Kraatz), comb. nov. (Figs 53, 160–162, 227) Lithocharis rufulus Kraatz, 1859: 140, 141. Medon (subg. Lithocharis) rufulus; Bernhauer & Schubert 1912: 243. Scopaeus rufulus; Cameron 1931: 171, 177. Type specimen examined: Lectotype ♂, Myanmar; labelled“76.”(handwritten),“India/orient.”(handwritten), “Holotypus” (red, printed), “Lithochar. / rufulus Kr. ” (handwritten), “Coll. Kraatz ” (printed), “Coll. DEI / Eberswalde” (printed), “Lectotype / Lithocharis rufulus / Kraatz, 1859 / des. Frisch & Herman, 2025” (SDEI); here designated. The number of specimens from which Kraatz (1859: 140, 141) described Lithocharis rufulus is not stated in the original description, but as male characters are described, at least one male must have been available to the author. Kraatz also did not designate a “type” [holotype by original designation (ICZN 1999: Article 73.1.1.)]. Thus, to stabilize the name Lithocharis rufulus according to ICZN 1999, Article 74.1., the only available specimen is designated the lectotype, a male from the Kraatz collection at SDEI, which is labelled “ Holotype ”, whose locality label is in accordance with the original description, and which bears handwritten labels which agree with the example of Kraatz’s handwriting in Horn et al. (1990: 482). New record: Thailand, Ranong, Kapoe: Khlong Nakha Wildlife Sanctuary (Phuket Mountain Range), 30 m, 29.I.1991, leg. Schwendinger (MFNB, MHNG). Redescription: Habitus (Fig. 53). Macrophthalmous, macropterous with palisade fringe of abdominal tergite VII. Body color unicolored medium brown; tip of abdomen, antennae, palps, and legs yellow brown. Labral denticulation type 4 (cf. Fig. 15); in lectotype sublateral labral denticles asymmetrically developed, obtuse dextrally and short-pointed sinistrally. Forebody surface microsculpture type 3 (Fig. 3). Sutural elytral row of punctures weakly impressed anteriorly, extending over approximately anterior 0.7 of elytral sutural length; medial and lateral elytral rows of punctures indistinct. Total body length 3.6 mm; forebody length 1.9 mm. Male: Abdominal sternite VII with very shallow, triangular emargination in median third of posterior margin. Abdominal sternite VIII in roughly posterior 0.2 of length with widely triangular incision continued anteriorly into very narrow, longitudinally aligned end (Fig. 227). Aedeagus (Figs 160–162) without apical lobe. Ventral process arising from aedeagus subapically and far dextrally and exceeding apical end of endophallic sclerite considerably in length; ventral process in lateral view thin, directed distoventrad, seemingly somewhat twisted in proximal half followed by somewhat wider distal half with slightly ventrad curved, subacute apical end (Fig. 160), in ventral view with narrow base close to dextral aedeagal margin, after that strongly curved distosinistrad toward sinistrally and convexly widened midlength portion, and gradually tapered toward narrow, acute, somewhat dextrad curved apical end (Fig. 162). Endophallic sclerite in dorsal and ventral view with elongate base almost as wide as width of aedeagus and in aedeagus situated medially (Figs 161, 162); endophallic sclerite mainly sinistrally expanded into huge, lobiform apical portion evenly curved ventrad, about heart-shaped in dorsal view, and considerably projecting from ostium (Figs 160–162); apical portion of endophallic sclerite at broad, emarginate apex ventrally extended in round dextral lobe (Figs 160, 161), shorter, narrow median denticle with proximad pointing tip (Figs 160, 161), and longer, wider sinistral tooth with ventroproximad pointing tip (Figs 160, 161). Endophallic foramen with smooth proximal margin, situated in median third of subapical width of apical end of endophallic sclerite (Fig. 162). Dorsal endophallic spine absent. Ostium with convex ventral margin and dorsal margin somewhat emarginate dextrally (Figs 161, 162). Shape of dorsal, midlongitudinal split of phallobase between types B and C (cf. Figs 39–41). Aedeagus in dorsal view narrow with parallel lateral margins (Fig. 162). Length of aedeagus 0.42 mm. Female unknown. Distribution: Frischianus rufulus was most probably described from southern Myanmar.The species that Kraatz (1859) described from “ India orient” were collected by Helfer 1836–1839 in the very south of Myanmar between Dawei [Tavoy] and the Tenasserim Range (cf. Kraatz 1859: 3, Schmidt-Göbel 1849: III). 130 years later, the species was eventually rediscovered in the south of Thailand.
