Lectotype designation: Redescription of this species below is based on two male specimens deposited in MNHN having syntype status. Wasmann (1893) mentioned four specimens (3 males, 1 female) in his original description from the following locality: Andrangoloaka, O.-S-O. von Annanarivo, Madagascar. The locality labels of both specimens from Paris bear the following hand written text:? Madagascar (Sikora)’, lacking Andrangoloaka. Wasmann commonly provided type localities that were only communicated to him verbally. Because both specimens were collected by Sikora, we are of the opinion that they can be treated as syntypes. One male is here designated lectotype, the second male is paralectotype, in order to ensure the stability of the nomenclature and to provide a unique name-bearing type for Semiclaviger sikorae.
Description. Body length 1.20–1.30 mm, maximum width in posterior corners of elytra, about 0.75 mm. Long setae arranged in lines on pronotum and lateral part of elytra, elytral disc almost lacking setae. Visible part of head (in dorsal view) six times as wide as long, Pronotum slightly more than twice as wide as long and five times as long as head. Elytra about 1.90 times as wide as long and 1.35 times as long as pronotum. Abdomen about as long as elytra, only composite tergal plate visible dorsally, median distance between prebasal tergal keels slightly more than twice the distance of keel to lateral margin of paratergite.
Sexual dimorphism. Female with simple mesotibiae, lacking long preapical spur.
Host ant: Crematogaster (Crematogaster) schencki Forel, 1891
Bionomics. All newly collected specimens were sifted from leaf litter in primary forest in Ambohitantely Special Reserve in central Madagscar, with subsequent extraction via a Winkler apparatus.
Distribution. The species was described based on four specimens from Andrangoloaka [Andrangolaoka], O.-S.- O. [west-south-west] von Annanarivo [Antananarivo] (Madagascar). The second locality is Gorge de la Mandraka, 1000 m (Jeannel, 1954: 332). The new record is from Ambohitantely Special Reserve, just to the north of Antananarivo. So far all known localities are in central Madagascar, close to Antananarivo, on the Central Plateau of the island (Fig. 28).
