Anthrenus (Florilinus) kompantzevi is a little known species of carpet beetle in the family Dermestidae native to Kyrgyzstan. Species have been noted from southwest part of Kyrgyzstan (specifically in Sary-Chelek Nature Reserve) to the Kyrgyz Ala-Too mountain range near canyons of Kara Balta river.

Male: The body is oval and convex. Black or brown, the antennae flagella and legs, except for the coxae, are reddish. The upper side is covered with brown, yellowish, or yellowish-gray and white scales, the underside with white scales, occasionally with a mixture of yellow scales. The head is covered with white scales, the crown with yellow scales. The inner edge of the eyes lacks an indentation. The antennae are 8-segmented with a 2-segmented club. The last segment is dark brown, the penultimate segment is brown or reddish, and the remaining segments are reddish. The club is 4.3 times longer than the combined length of the preceding four segments. The length of the last segment is 3.3 times its maximum width and 10.8 times the length of the previous segment. The pronotum is uniformly convex, transverse, and 1.8 times shorter than its width at the base. From the posterior angles, it tapers slightly and then more strongly towards the anterior edge. The antennal fossae occupy 0.66 of the lateral edge of the pronotum. The posterior edge is bi-emarginate. The disc and anterior edge are covered with yellow scales, sometimes mixed with brown scales, the sides, posterior angles, and a small spot before the scutellum are covered with white scales. The elytra are 1.2 times longer than their combined width and 3 times longer than the pronotum. The surface of the elytra is covered with yellow or yellowish-gray scales, sometimes with patches of brown scales. White scales form three transverse bands, sometimes breaking into separate spots, and a small apical spot. The underside is covered with white scales, occasionally with a mixture of yellow scales on the abdominal sternites. Length 2.2-2.5 mm, width 1.4-1.5 mm.
Female: Differs in the structure of the antennae, the club being 2.8 times longer than the combined length of the preceding four segments. The length of the last segment is 3 times its maximum width and 5.3 times the length of the previous segment. The lateral edges of the pronotum are more evenly rounded, and the length of the elytra exceeds the length of the pronotum by 3.6-3.7 times. Length 2.2-2.6 mm, width 1.3-1.5 mm.
Differential diagnosis
Within subgenus Florilinus (characterized by 8-segmented antennae), the species can be distinguished through differences in the shape of the aedeagus and the structure of the antennal club. Specifically, the final segment of the club is nearly 11 times longer in males and 5.3 times longer in females compared to the preceding segment.
Etymology
The species is named in honor of A.V. Kompantsev, who collected the type specimen that was later provided to Zhantiev.
