Cycreon armandi  Shatrovskiy, 2017: 589.

Type locality.

Singapore.

Material examined.

None (information adopted from Shatrovskiy 2017).

Diagnosis.

Cycreon armandi  can be distinguished from other known species by the deeply incised clypeus, the semicircular impressions (punctures) on the pronotum, and the curved meso- and metatibae.

Addition to description.

Body 3.3 mm long; colouration completely light reddish-brown; clypeus about 2 × as wide as long, anterior margin of clypeus strongly emarginate medially (Fig. 5K); frons and clypeus with small and not so closely disposed punctures; mentum (Fig. 5L) subtrapezoid, widest at posterior fifth, about 1.8 × wider than long, with a deep anteromedian emargination reaching beyond the anterior fourth of length; pronotum with dense and shallow, punctation consisting of small setiferous half-moon shaped punctures (Fig. 5M); meso- and metatibiae curved (Fig. 5S); median projection of sternite 9 rounded apically (Fig. 3M); aedeagus (Fig. 3L) with phallobase 0.6 × as long as parameres, almost symmetrical, manubrium narrow and very; parameres continuously narrowing towards apex; median lobe moderately wide (Fig. 3K), slightly constricted in apical fourth; apex acuminate, triagular.

Distribution.

Only known from the type locality in Singapore (Fig. 7).

Remarks.

According to Shatrovskiy (2017) the proportions of the clypeus are given as 3 × as long as wide, however, the picture in the paper ( Shatrovskiy 2017: 591) shows that the ratio is closer to 2.0 ×.
