Genus Apatenia Pascoe, 1859

Type species: Apatenia viduata Pascoe, 1859 , by original designation (described from Borneo).

Apatenia viduata Pascoe, 1859: 434 . Gemminger & Harold 1872: 2735 (catalogue); Bovie 1906: 257 (catalogue); Wolfrum 1929: 41 (catalogue), 1953: 18 (catalogue), Rheinheimer 2004: 44 (catalogue).

Pictures/drawings of Malagasy Apatenia : Frieser 2000: 51 (fig. 4–dorsal habitus of Apatenia oculifera Frieser, 2000 ; fig. 5–dorsal habitus of Apatenia sulcicollis Frieser, 2000 ); Rheinheimer 2004: 44 (catalogue), 221 (fig. 93–dorsal and lateral habitus of Apatenia sulcicollis Frieser, 2000 ); Frieser 2010: 20 (fig. 1–dorsal habitus of Apatenia fallax Frieser, 2010 ); Trýzna & Baňař 2013: 506, Apatenia stysi Trýzna & Baňař, 2013 , figs 1–4, female holotype (1–dorsal habitus, 2–head and pronotum, 3–head, 4–lateral habitus), 508, Apatenia quadristigma Frieser, 1981 , figs 5–6, female allotype (5–dorsal habitus, 6–head), 509, A. quadristigma , figs 7, 9, 12 (7–head, 9–right antenna, 12–dorsal pronotal carina), A. stysi , figs 8, 10–11, 13–14 (8– head, 10–right antenna, 11–abdomen, 13–dorsal pronotal carina, 14–pygidium), 510, A. stysi , figs 15–18 (15–hemisternites, 16–segment VIII, 17–toothed plate of right hemisternite, 18–bursa copulatrix and spermatheca).

Diagnosis of Apatenia . Head long, narrow, rostrum lengthened, flat and broad, mandibles robust, strongly toothed. Eyes laterally situated.Antennae inserted at about midway between anterior margin of eyes and mandibles. Antennae longer than head, antennomeres I and II thick, III–VI more or less cylindrical, VII–VIII subtriangular, IX–XI forming loose club with antennomeres IX and X triangular, terminal antennomere rounded. Pronotum slightly transverse, narrow in front. Dorsal transverse carina of pronotum antebasal or sub-basal, its lateral margins directed anteriorly to about halfway along the side of prothorax. Elytra slightly depressed. Legs moderate, tarsi rather short.

Notes. The classification of the genera Apatenia and Phaulimia (both placed in the tribe Platyrhinini Bedel, 1882 , according Trýzna & Valentine 2011, Trýzna 2017) need to be revised. Both genera contain numerous species, and occur in a large area (Oriental, Afrotropical and Australian distribution). Their generic descriptions were based upon the description of the first included species and have not been suitably adjusted to accommodate all subsequently described species. It is likely that the two genera will be maintained but perhaps with different species compositions. This will be the subject of future studies.
