Acylophorus kambuiensis Bordoni, 1994: 312 .

Acylophorus kumbuiensis: Herman, 2001: 3032 (misspelling).

Diagnostic characters. Bordoni’s description contains illustrations of the aedeagus, head, maxillary palpi and posterior tarsi in addition to a textual description of morphological features. The following section contains additional diagnostic features as well as variations exhibited by further specimens studied.

Length 8–9mm (The figure in the original description of 10 mm for overall body length does not agree with my own measurements of type material). Body black, pronotum and hind margins of tergites brown. Abdomen very weakly iridescent. Legs pale. Antennae dark with apical segments conspicuously pale. The maxillary palpi are all pale. Labrum black.

Head somewhat large (pronotum 1.6x wider than head), slightly transverse (1.1x wider than long) with well developed temples and antennal insertion close to front margin with narrow pigmented strip in front ( Fig. 26 ). Pubescence extending over most of head leaving only a central glabrous strip free of punctures. Two pairs of interocular setae. Five postocular setae visible, the posterior puncture and seta displaced forward and out of line. No additional short seta on hind margin of eye. Maxillary palpi with terminal segment elongate, glabrous, asymmetric and attenuated at apex ( Fig. 75 ). First segment of antenna as long as next five. Segments I to VIII elongate, X transverse ( Fig. 102 ).

Pronotum only slightly transverse (1.2x wider than long) with rounded sides and widest in basal half. Covered with somewhat sparse semi-erect pubescence. Dorsal setae absent. One pair of lateral setae. Marginal setae shorter than in A. orientalis . Elytra transverse (1.55x wider than long) with pubescence arising from strong, somewhat close asperate punctures. Apical fringe of thick bristles shorter than the hairs on the rest of the elytra. Abdominal tergites with long, somewhat outstanding pubescence arising from asperate punctures that are much denser at the base of each tergite than the apical half.

Paramere simply lobed, pegs confusedly arranged at apex with blank area right at the tip in the centre (Fig. 138). Median lobe with rather narrow, very flat apex, only just surpassing paramere.

Type material. Paratype 3: “S. Leone W. area Sugar Loaf Mt. Rossi 7.3.92 / PARATYPUS Acylophorus kambuiensis sp. n. Bordoni det. 1992” (cBord).

This species was given the manuscript name, A. leonensis , by Cameron. A type was labelled accordingly, but he never published a description.

Further material examined. SIERRA LEONE: Eastern Province: near Kenema, Kambui Hills, W Rossi, 27–29. x.1989, 13 (teneral) (cLott); Western Area: Freetown, no date, 3Ƥ ( BMNH). Distribution and bionomics. All records so far come from Sierra Leone ( Fig. 148 ), where it has been found on the banks of streams.

Comparative notes. Distinguished from A. lualabaensis by the larger eyes, the pattern of the pubescence on the pronotum and the form of the aedeagus.
