Thyreocephalus wallacei View in CoL nov.sp. ( Figs 3-6 View Figs 3-9 )
E x a m i n e d m a t e r i a l: Holotype: S-Celebes, Ujung Pandang, F. Lenzi 15.VIII.2009 (cB).
D e s c r i p t i o n: Body length 11,5 mm; length from anterior margin of head to posterior margin of elytra 6,5 mm. Small species.
Black slightly reddish, with almost red genital segment. Head sub-quadrangular, with rounded sides. Eyes small, with diameter as long as the 2°-3° antennomeres together. Surface with very deep, dense puncturation, a part a narrow median strip, and with one very superficial puncture at the end of the ocular grooves. Labrum as in Fig. 3 View Figs 3-9 .
Pronotum narrower and longer than head, with sinuate sides. Surface with a puncture near the anterior angles and with some punctures along the lateral margins. Elytra narrower, slightly wider than pronotum, with marked humeral angles. Surface shiny, with deep, fine and regular puncturation, arranged in numerous series.
Abdomen shiny, with fine and dense transversal micro-striation and dense puncturation on the sides, with long yellowish setae.
Tergite and sternite of the male genital segment as in Figs 4-5 View Figs 3-9 . Aedeagus ( Fig. 6 View Figs 3-9 ), 1,22 mm long, very narrow, with symmetrical parameres; not evident inner sac.
D i s t r i b u t i o n: Known from the type locality only.
E t y m o l o g y: Dedicated to Alfred Wallace (1823-1913) that landed on the island in 1859. To this very important explorer and naturalist besides was dedicated only one Staphylinid: S tenus wallacei PUTHZ 1968 , synonym of S. nothus BENICK 1929.
N o t e: This species is very closely in dimension, coloration and puncturation to T. bakeri BORDONI 2002 , known only for a female from Luzon ( Philippines), but differs for the following characters: punctures on the head non forming divergent striolae, different shape of labrum, pronotum longer than head, without two lateral strip of large punctures. Would be useful therefore the study of a male of T. bakeri , since they are known links between Philippines and Celebes.
