Material studied: Holotype, ♁: SÃO TOMÉ, with three labels „ SÃO TOMÉ, 1324m / Antenna, Bom Successo / 00°16′31′′N, 06°36′14′′E / (21–29). x.2016, FIT“ [white, printed], “ Turner, C. R., Tasane, T., leg. / BMNH (E) 2017- 11 / TripRef: ST-001 ( ANHRT 21 )” [white printed], “QR code / NHMUK010584423 ” [white printed] ( BMNH) . Paratypes: 2♁♁, 2♀♀: same data as for holotype (BMNH, PCPH) .

Diagnosis. As for the genus, see above. Aedeagus symmetrical, with median lobe subcircular, distal portion with three projections; endophallous lacking sclerites; parameres expanded to apex, lacking setae, slightly longer than median lobe.

Description. Body light reddish-brown, maxillary palpi and legs slightly lighter; body moderately shiny, with fine, dense setae. Body length 1.95–2.10 mm, maximum width 0.72–0.75 mm.

Head about as long as wide; with two distinct, asetose, well-separated dorsal tentorial pits, located in median line of eyes, distance between them slightly superior to distance from pit to lateral margin of eye; eyes large, slightly proturberant, clearly shorter then temples.

Antennae about 0.75 – 0.77 mm long, all antennomeres elongate, scape about 1.2 times as long as pedicel and about twice as long as wide; pedicel 1.6 – 1.7 times longer than wide and about 1.3 times as long as 3, antennomeres 3 1.33 times as long as 4, 4 and 5 equal in length, antennomere 6 1.15 times as long as 5 and 1.4 times as long as 7, antennomeres 7 and 8 equal in length, 7 and 8 equal in length, 9 1.2 timeas long as 8, 10 1.15 as long as wide, 1.3 times as long and 1.4 as wide as 9, terminal antennomere poited at apex, twice as long as 10.

Pronotum transverse, widest in mid length, 1.15 times as wide as long, 1.1 times as long as head. Median fovea punctiform, lateral antebasal foveae well-defined, all asetose, lacking transverse antebasal sulcus.

Elytra subtrapezoidal, lacking basal foveae, striae or carinae; with fine, dense setation.

First visible abdominal tergite (IV) twice as long as second (V), second (V) 1.3 times as long as third (VI) which is 1.6 times as long as fourth (VII).

Legs short and slender, all femora clavate, tibiae and tarsi slender; tarsi longer than half length of tibiae.

Aedeagus ( Figs 11 – 12 ) symmetrical, with median lobe subcircular, 0.35 mm long and 1.25 as long as wide; parameres 1.15 times as long as median lobe, lacking setae.

Distribution. São Tomé.

Natural History. All known specimes were collected by flight intercept trap. No other details concerning the ecology of the species is known.

Etymology. Named after Tınis Tasane, one of collectors of the type series.
