Megalopinus creberrimus (L. Benick, 1941)

Megalopinus creberrimus (L. Benick, 1941) View in CoL ( Figs 5A, B View Figure 5 )

Specimens examined: male, ‘ Philippines: Mindanao, Dominorog , Bukidnon, Sept. 2022, leg. local collector’ / ‘ Megalopinus creberrimus (L. Benick, 1941) , det. Mainda 2024’ (cTM) .

Note: The examination of a specimen from Dominorog, Bukidnon in Mindanao Island provides a new distribution record for the species which until now was only known from the islands of Palawan and Borneo ( Sabah). The intraspecific color variation of this species was already noted by Puthz (2012). However, other diagnostic characters such as the punctation of the elytra, the lateral striae on tergite V and especially the internal structure of the aedeagus ( Puthz 2012: Fig. 85) are more helpful in identifying the specimen as belonging to M. creberrimus . The study of this species makes it necessary to designate a further elytral puncture-row (cf. Mainda 2022): epipleural row (epr) for a row directly lateral to the sublateral row (slr), Fig. 5B View Figure 5 .

Description: Habitus as in Fig. 5A View Figure 5 . Measurements: BL: 3.30 mm, DE: 0.60 mm, FBL: 2.00 mm, EL: 0.83 mm, EW: 1.08 mm, HW: 1.03 mm, PL: 0.70 mm, PW: 0.85 mm, SL: 0.65 mm. Head and pronotum blackish; elytra with reddish falciform patch in middle of dorsal row on each elytron ( Fig. 5B View Figure 5 ); abdomen dark brown, paratergites slightly lightened, basal striae of tergite V extending at most to middle; antennae and legs yellow. Punctures of left elytron: epr (3), slr (6), shr (5), dsr (7), ssr-c (10), str (9); punctures of right elytron: epr (3), slr (7), shr (7), dsr (6), ssr-c (14), str (9).
