Phradonoma blabolili sp. n. from Angola is described and illustrated. Key to the Afrotropical “Phradonoma nobile species group” to which the newly described species belongs, as well as key to genera of dermestid beetles occurring in Angola is given. List of all species of Dermestidae known to occur in Angola hitherto is provided.


Taxonomy, new species, Coleoptera, Dermestidae, Phradonoma, Angola


The family Dermestidae (Coleoptera: Bostrichoidea) contains about 1440 species and subspecies worldwide (Háva 2003a, Háva and Solervicens 2012). Its members are “mainly scavengers on dried proteinaceous material and are of economic importance because the family includes species that are pests of stored products or natural-history enemies” (Lawrence and Ślipiński 2005). Despite their species richness, only 14 species have been reported from Angola hitherto (Erichson 1843, Ferreira 1965, Háva 2003a, b, Kadej 2006, 2010, Mroczkowski 1968, Pacavira et al. 2006, Pic 1931, 1937). This doubtlessly small number is perhaps largely due to the 27 years of Angolan civil war (1975–2002) which was a serious impediment to entomological research; the actual number of species is undoubtedly much higher. After the end of the conflict, and especially in the recent years, specialists carrying out entomological research seem to be returning to Angola. The genus Phradonoma Jacquelin du Val, 1859 is distributed largely in Palaearctic and Afrotropical regions and one species has been introduced into the U.S.A. In this contribution to the taxonomy of Angolan Dermestidae (Coleoptera) we describe one new species of Phradonoma and provide a summary of the dermestid taxa occurring there.

Material and methods

The type specimen of this new species has been collected using flight intercept trap in open savannah near Catabola, in the central Angolan province of Bié, in altitude 1300 m. The FIT trap has been placed near a small pond, and cow dung, rotting bananas as well as rotting fish were all used to attract insects. The attractants were placed in small plastic containers around the trap. When removing the male terminalia from the specimen, the entire abdomen was first severed from the rest of the body, subsequently macerated in KOH heated up to 90°C for a short while, cleared in 96% ethanol and thence the male genitalia was removed from the cleared abdomen. The habitus photographs of Phradonoma blabolili was taken by macroscope Leica 216 APO. The dissected male genitalia was macerated in 10 % solution of KOH heated up to 90 °C for a few minutes, cleared in Xylene and transferred into glycerin in small glass dish where it was observed. The photograph of the male genitalia has been taken with Olympus BX 41 camera. The map on Fig. 5 depicting the type locality of Phradonoma blabolili was downloaded from the Internet and subsequently re-drawn using Adobe Illustrator CS4. The type specimen is deposited in the collection of the senior author (JHAC).

Standard measurements have been made according to Háva (2006) and are as follows:

BL Body length - linear distance measured from anterior margin of pronotum to apex of elytra;

BW Body width - measured between two anterolateral humeral calli;

PL Pronotum length - measured from the top of the anterior margin to scutellum;

PW Pronotum width - measured between the two posterior angles of pronotum;

EL Elytral length- linear distance measured from shoulder to apex of elytron.

Type material.

Holotype, male, with printed label “Angola, Bié province, Catabola env., 15–27.11.2012, FIT trap, T. Lackner lgt.” (JHAC).


Male. Body measurements: BL 2.20 mm; BW 1.30 mm; PL 0.60 mm; PW 1.10 mm; EL 1.70 mm. Body (Fig. 1) dark brown and black, elongate oval. Head entirely black, coarsely punctuate, with decumbent light brown setae; maxillary palpi dark brown. Eyes large, with short microscopic setae. Antennae with 11 antennomeres, antennal club consisting of 3 antennomeres; antennomeres I-VIII brown, antennomeres IX-XI black, furnished with short setae (Fig. 2). Frons with small dark brown ocellus. Pronotum entirely black, shiny, sparsely and finely punctuate, with dark and semi-erect setae medially, white setae increase in number towards the lateral margins, posterior edges and in ante-scutellar area; lateral pronotal margins not visible from above. Scutellum small, black and triangular, asetose and impunctate.

Elytra black in anterior half, dark brown on posterior half, sparsely and coarsely punctuate; sparsely covered with semi-erect dark setae. Each elytron bears four transverse fasciae formed by intermixed white and yellow setae: the first situated near scutellum; second present anteriorly, reaching elytral suture; third fascia situated sub-medially reaching elytral suture; and the fourth fascia situated sub-apically, reaching elytral suture. Elytral epipleuron short, black, with dark setae.

Metaventrite finely punctuate with white, short, recumbent setae. Mesoventrite coarsely punctuate laterally, medially finely punctuate, and covered by white, short, recumbent setae.

All abdominal ventrites black, covered by short, white, recumbent setae; first abdominal ventrite with distinct oblique discal striae.

Legs. Tibiae and tarsi brown, femora anteriorly darkened and sparsely covered with fine white setae. Anterior tibiae with black spines along shaft.

Male genitalia. Parameres widely ‘open’ connected anteriorly by a ‘bridge’, parameres apically with pseudopores and short setae; basal piece strongly sclerotized; penis apically with downward pointing ‘hook’. Penis has been slightly damaged during the manipulation with the aedeagus and therefore we decided to show the photograph as well as the drawing of the aedeagus depicting a reconstructed penis. (Figs 3-4).

Female unknown.

Differential diagnosis.

This new species belongs to the genus Phradonoma Jacquelin du Val, 1859, and can be placed into the “Phradonoma nobile species group” (sensu Háva 2006; see also below). Phradonoma blabolili sp. n. is visually most similar to Phradonoma cornelli Háva & Hermann, 2009 and can be differentiated from it by the characters given in the key.

Key to the Afrotropical “Phradonoma nobile species group”

Phradnonoma nobile species group” of the genus Phradonoma can be defined by the combination of the following putative synapomorphies: cuticle bicolored, dorsal body surface with bi- or tri-colored setae and antennal club consisting from three antennomeres (see also Háva 2006).
