Paratype ♂: the same data as holotype only, second label: " NHMUK 013317340 " [RQ code], determinate label is: " PARATYPE Heterocerus havai SKALICKÝ det. Skalický 2019" [red label] CSU .

D e s c r i p t i o n: Holotype ♂: Total length 3.65 mm (measured from labral apex); elytra 2.65 mm long, 1.40 mm wide across their lateral margin. Ground colour pale brown, elytra and pronotum with black to brown pattern as in Fig. 1 , labrum, head and scuttelum black, protibiae darker laterally. Ventral surface brown. Visible part of labrum ( Fig. 3 ) wider than long (ratio 1.25: 1), triangular, lateral angles rounded, anterior angles truncate, softly serrate in median portion, surface of labrum finely granular, with dense short yellowish setae. Mandibles ( Fig. 3 ) somewhat curved, bluntly dentate, dorsal subapical tooth imperceptible, rounded, dorsal process of dental lobe short, provided with a simple spike and a pronounced sharp lateral horn. Prostheca with fine teeth on dental lobe, without a prosthecal notch. Antennae 11-segmented, with a 7-segmented club, scape triangular, pedicel oval, antennomeres 1 and 2 with sparse, long erect setae. Clypeus ( Fig. 3 ) with a pair of relatively long and set far apart anterior horns. Anterior margin of clypeus shallowly emarginate, with dense, short, yellowish setae intermixed with long erect ones. Head finely granular, setae sparse, short, intermixed with long erect setae above eyes. Pronotum oval, wider than long (ratio 1.65: 1), as wide as base of elytra, pronotal base completely rimmed; lateral margins serrated; anterior margin with depressions under the eyes. Surface of pronotum very finely granulated without intermixed longer punctures; setae sparse, short, yellowish. Scutellum pointed, triangular, about 1.5 times longer that wide, anterior margin convex. Elytra with distinctive longitudinal furrows with scutellar depressions and well-developed humeral depressions extending obliquely towards suture reaching midlength of elytron. Lateral margin and base of elytra coarse and distinctly dentate, teeth most pronounced around the shoulders ( Fig. 2 ). Surface of elytra microgranular, with intermixed punctures approximately twice large as eye facets. Setae on elytra yellowish, double, short adjacent and sparse long semierected. Epipleural ridges absent. Ventral surface sparsely setose. Metaventrite with postmesocoxal ridge. Mesoventrite with three short, square and blunt spines in front of each mesocoxa. Protibia with 8 stout spines along its lateral margin and two spines at its inner apical angle, meso- and metatibia with an uncertain number of thin waeak spines (in paratype mesotibiae with 7 and metatibia with 8 weak spines). Tibiae with dense, long setae. Post-metacoxal line incomplete. Stridulatory arch marked, with poor visible of striae. Spiculum gastrale 0.70 mm long, V-shaped as in Fig. 4 , arms firmly connected apically. Aedeagus 0.80 mm long, well sclerotized, shape as in Figs 5-8 . Parameres long, firmly connected to phallobasis; supporting sheath border posteriorly. Penis without processus accessorius, without internal sac.

Female: unknown.

D i f f e r e n t i a l d i a g n o s i s: Due to the shape of the aedeagus (Parameres firmly connected with phallobasis; penis simple without processus accessorius and inter-

nal sac) H. havai nov.sp. belongs to the bredoi group sensu CHARPENTIER (1965). This group contained nine previously described taxa in Ethiopian region: H. abyssinicus MAMITZA, 1930 ( Ethiopia, Kenya, Tanzania, Zaire, Zambia), H. bredoi MAMITZA, 1931 ( Botswana, Chat, Congo, Namibia, Zaire), H. denticulatus MAMITZA, 1930 ( Benin, Congo, Nigeria, Zaire), H. fairmairei GROUVELLE, 1906 ( Madagascar), H. meridionalis PÉRINGUEY, 1892 ( South Africa), H. pavliceki SKALICKÝ, 1999 ( Namibia), H. peringueyi GROUVELLE, 1919 ( South Africa), H. sennarensis GROUVELLE, 1909 ( Mali, Nigeria, Sudan, Zambia) and H. snizeki SKALICKÝ, 1996 ( Kenya, Tanzania) (MASCAGNI & MONTE (2001, 2002, 2003a, 2003b, 2005), SKALICKÝ (1996, 1999)). The morphology of male genitalia and spiculum gastrale of H. havai nov.sp. differs from all above mentioned species, the most similar species with respect to external characters being H. meridionalis (mandible with pronounced sharp lateral horn), It differs from the abovementioned species in the elytral pattern, absence of dentate of shoulders and lateral margins of pronotum and distribution. Two species: H. denticulatus and H. sennarensis have dentate of shoulders, but not dentate lateral margins of pronotum as H. havai nov.sp. (see Figs 15,16, 40, 47, 71, 72, 73, 114, 116 and 117 in CHARPENTIER (1965) and Figs 1-8 in this paper).

E t y m o l o g y: The new species is named after my friend, Czech coleopterologist ( Coleoptera : Dermestidae ) Jiří Háva (Únětice u Prahy, Czech Republic).
