description: Platymetopus flavilabris punctulatus (MacLeay, 1825)
(Figs. 32–34, 39–41)
Harpalus punctulatus MacLeay, 1825: 21. Type locality: “ Java ”, Indonesia.
Platymetopus subrugosus Schauberger, 1938: 39, syn. n. Type locality: “ Celebes: Makassar ”, Sulawesi, Indonesia.
Type material examined. Holotype of Platymetopus subrugosus: female, with labels “ Celebes ”, “Mak. 66”, “ Platymetopus sp., H.E.A.”, “Holotypus”, “ Coll. Germar —Schaum”, “Type”, “ Platymetopus subrugosus Schaub., det. Dr. E. Schaub. 34”, “DEI Eberswalde”, and ″DEI Müncheberg, Col—01737” (DEI). Paratype:female, “ Celebes ”, “ Platymetopus sp., H.E.A.”, “ Coll. Germar —Schaum”, “ Cotype ”, “DEI Eberswalde”, “ Platymetopus subrugosus Schaub. ”, and “DEI Müncheberg, Col-01738” (DEI).
Additional material examined. Indonesia. Java: 1 male, 1 female, “ Ostjava, pasir Putih ”, 5–7.IV.1988, Richter leg. (NHMW); 1 male, 1 female, “E Java ” (MFNB). Sumbawa: 1 male, “Sumbava” (ZIN).
Description. Comparatively small: body length: 7.6–8.1 (m 7.9) mm. Body proportions in Table 2. Habitus as in Figs. 32 and 33.
Head densely punctate on frons and vertex, without microsculpture, with weakly convex eyes. Antennae comparatively short, slightly surpassing pronotal basal margin or not reaching it; infuscate from apical half of antennomere 3 or 4. Pronotum coarsely rugose-punctate, without microsculpture between punctures, elytra comparatively short. Proepisternum somewhat coarsely and densely punctate. Legs yellow or brownish yellow, with femora not darker than tibiae; tarsi more or less infuscate. Male genitalia as in Figs. 39 and 40.
Comparison. In combination of the characters, this subspecies is very similar to P. flavilabris laticeps, differing from it mainly in having legs yellow or brownish yellow, with femora not darker than tibiae. This subspecies is also characterized by on average smaller size, less convex eyes and shorter elytra.
Distribution (Fig. 41). Known from Java, Sumbawa and Sulawesi (Indonesia). Probably, the same subspecies also occurs on Sumba (Louwerens 1964) and Timor (Baehr & Reid 2017).
Remarks. Platymetopus subrugosus was described from four specimens from Makassar, Celebes (Sulawesi) (Schauberger 1938) and hitherto considered a separate species (Lorenz 2021). Platymetopus punctulatus, originally described from Java (MacLeay, 1825) and re-described based on a syntype at NHML by Andrewes (1919), has since been treated as a synonym of either P. flavilabris (Andrewes 1921 a, Habu 1973) or P. f. var. thunbergi (Andrewes 1930, Csiki 1932). My examination of the type series of P. subrugosus and comparison it with the photograph of the male syntype of P. punctulatus labelled “ punctulatus Mac. ”, “Type H.T.”, “ Java Horsfield. 60–15”, “60–15 E.I.C.” “33” and “34” (NHML), revealed that two these species are based on the same taxon, which I treat as subspecies P. f. punctulatus.
