Anthrenus (Anthrenus) kittenbergeri Holloway and Herrmann , new species
( Fig. 4 View Figure 4 )
Holotype male. Assab , Eritrea (13.022, 42.738), 1907, K. Kittenberger leg. Deposited in AHEC GoogleMaps . Paratypes. Two males, same data as holotype, deposited in AHEC.
Description, external characteristics. Holotype ( Fig. 4A View Figure 4 .), BL = 2.0 mm, BW = 1.43 mm. Head with single dark brown or black ocellus centrally, below level of top of eyes. Eyes notched at lower inner margins. Integument of head, thorax, and base of elytra dark brown, becoming red towards elytral apices. Head and thorax entirely coated in pale orange scales with white scales concentrated at posterior pronotal angles. Elytra similarly covered in orange and white scales; white scales concentrated in pre- and postmedian fasciae, with basal and sub-apical spots.
Ventrites ( Fig. 4B View Figure 4 ) with dark brown integument, covered in white scales. Ventrites 2 to 5 with scales tinted brown, growing darker towards the margins. Ventrite 1 with two vertical, almost parallel (slightly diverging) postcoxal lines crossing ventrite 1 either side of midline and turning inwards slightly at the tip.
Antenna with 11 antennomeres ( Fig. 4C View Figure 4 ), AL = 146 µm, AW = 97 µm, entirely red. Antennal club formed by last three antennomeres. Legs red; outer surface of femur densely coated in white scales.
Description, internal characteristics. Aedeagus ( Fig. 4D View Figure 4 ) broad and short (relative to A. kushangaza ). Parameres (PL = 309 µm) rod-shaped, broader in the posterior half than the anterior half. Parameres diverge from the base, curve round towards posterior, before progressing to the posterior tips as two slightly diverging rods (outer margins are concave). Parameres with broad, flat rounded tips that point in towards each other, but do not meet at the midline. Aedeagus uniform pale brown, tips of parameres paler. Parameres with inner margins that parallel margins of median lobe and wrap around tip of median lobe.
Median lobe (ML = 312 µm) very broad (broader than A. kushangaza ); apex blunt, rounded. Posterior tip of median lobe not extending as far as tips of parameres. Median lobe with two long, curved stirrups (one broken) at anterior end.
Morphometrics. Holotype BW/BL = 0.72, indicating that A.kittenbergeri has a broader profile than A. kushangaza .
Distribution. Anthrenus kittenbergeri was collected in southern Eritrea ( Fig. 5 View Figure 5 ).
Etymology. Anthrenus kittenbergeri is named after the collector of the holotype, Kálmán Kittenberger.
Differential diagnosis
Both species described here came from north-eastern Africa. Only one other species comes from this region belonging to the subgenus Anthrenus and has rod-shaped parameres as described here: A. crustaceus Reitter, 1881 . Háva (2014) produced clear illustrations of A. crustaceus antenna ( Fig. 6A View Figure 6 ) and aedeagus ( Fig. 6B View Figure 6 ) to differentiate between A. crustaceus and another species with rod-shaped parameres, A. kubistai Háva and Votruba, 2005 (no image of the habitus was provided). The illustrations produced by Háva (2014) differ from A. kushangaza and A. kittenbergeri in several ways. Anthrenus crustaceus antenna ( Fig. 6A View Figure 6 ) has a large, rounded terminal antennomere producing an obvious step between the 10 th and the 11 th antennomere, and a small 1 st antennomere, much smaller than the 2 nd antennomere. The antennae shown in Figures 2A View Figure 2 and 4C View Figure 4 do not have rounded 11 th antennomeres that produce a step between the 11 th and the 10 th antennomere, and the 1 st antennomere is the same size as the 2 nd antennomere.
The aedeagus of A. crustaceus ( Fig. 6B View Figure 6 ) is long, narrow, with parallel sides, immediately differing from the aedeagus of A. kittenbergeri ( Fig. 4D View Figure 4 ), which is broader and shorter with slightly concave outer margins. The median lobe of A. crustaceus ( Fig. 6B View Figure 6 ) does not extend as far to the paramere tips as that of A. kushangaza ( Fig. 2B View Figure 2 ). The flattened paramere tips of A. crustaceus ( Fig. 6B View Figure 6 ) are larger and curve in to the extent that they overlap, differing from A. kushangaza paramere tips which are smaller and do not overlap ( Fig. 2B View Figure 2 ).
Another potential confusing species is A. rauterbergi Reitter, 1908 . Only a single paratype female was available for comparison (AHEC, Fig. 7 View Figure 7 ). Anthrenus rauterbergi has a broader, shallower pronotum (length/width = 0.427) than A. kushangaza and A. kittenbergeri (length/width = 0.475, and 0.512, respectively). The postcoxal lines in A. rauterbergi diverge all the way to the tips ( Fig. 7B View Figure 7 ) but are almost parallel in A. kittenbergeri and curve inwards at their tips ( Fig. 5B View Figure 5 ). The antennal club of A. rauterbergi is broader than A. kushangaza (AW/AL = 0.77, and 0.63, respectively).
