Calampocus zambiaensis

sp. n.

Calampocus zambiaensis sp. n.

( Figs 1 View FIGURE 1 , 3 View FIGURE 3 )

Description. Length. Ƌ: 2.1–2.7mm (mean 2.4mm, 2 specimens)

Colour. (Ƌ, Fig. 1 View FIGURE 1 D–F). General coloration black to blackish brown. Fore and middle legs yellowish brown; hind legs darker brown becoming yellowish brown toward tips of tibiae and tarsi. All legs with spinal apices black.

Habitus. Coryphe and metope joined at about 90° angle ( Fig. 3 View FIGURE 3 A). Coryphe hexagonal with lateral margin angled to fore margin; posterior margin straight; slightly depressed each side of mid-line. Metope strongly angled ventrally to face, rugose, without carinae ( Fig. 1 View FIGURE 1 E). Postclypeus large and swollen with a longitudinal medial ridge, fairly smooth. Rostrum with apical segment quadrate in lateral view, one-third length of pre-apical segment. Antennal pedicel with rounded apical process ( Fig. 3 View FIGURE 3 B). Pronotum shorter than coryphe, anterior margin very slightly convex, posterior margin straight, smooth. Scutellum smooth, very tip covered in transverse wrinkles. Coryphe, pronotum and scutellum fairly smooth with a few indistinct pits. Brachypterous with fore wings reaching hind margin of the second visible abdominal tergite, venation obscure ( Fig. 1 View FIGURE 1 D). Fore tibia quadrate in cross section ( Fig. 3 View FIGURE 3 D). Hind tibia with single lateral spine ( Fig. 2 View FIGURE 2 G). The first metatarsomere approximately as long as the second and the third metatarsomeres combined, the first and the second apically with two lateral spines either side of a pad with small pimples ( Fig. 2 View FIGURE 2 G).

Male genitalia. Anal tube (10th segment) rounded and slightly longer than wide in dorsal view, gradually tapering to blunt apex in lateral view ( Fig. 3 View FIGURE 3 K). Pygopher very short with hind and fore margin concave, without processes ( Fig. 3 View FIGURE 3 I). Style broad in lateral view, upturned apically and produced into an elongate acute processes (capitulum), without lateral tooth, caudo-dorsal angle widely rounded ( Fig. 3 View FIGURE 3 H). Aedeagus surrounded by weakly sclerotized hood-like phallobase, extended caudally as a pair of broad, laterally compressed asymmetrical lobes. Aedeagus complex, with a dorsal and ventral lobe the latter with a pair of elongate, acuminate, spirally curved hooks, right hook running underneath the phallobase and protruding from its ventral margin, left hook curved dorsally beneath and above phallobase ( Fig. 3 View FIGURE 3 J, L).

Type material examined. Holotype Ƌ, pinned, with genitalia in a separate microvial: “ Zambia, Hillwood , termite hills, dung pitfall trap, 21–28 Oct. 2013, R. Smith, H. Takano, L. Chmurova and L. Smith ”, ( NHM).

Paratypes. 2 Ƌ, same data as holotype ( NHM).

Etymology. This species is named after the country of collection.

Remarks. In Gnezdilov & Bourgoin’s (2009) key this species runs to couplet 14 as the male has a globular head etc. The three genera under this couplet (the monotypic Calampocus Gnezdilov & Bourgoin and Issopulex China & Fennah and Savanopulex Dlabola with two species) all have the male similar in appearance to our species, i.e. shiny black and globular. However, our species has features in common with both parts of couplet 14, i.e., the ventral aedeagal hooks are spirally curved as in Calampocus sphaeroides Gnezdilov & Bourgoin but it is similar to the other two genera in lacking a single spine between the outer metatarsomere spines ( Fig. 2 View FIGURE 2 F) and the phallobase lacking a large basal process. Other differences between the three genera were summarised by Gnezdilov (2009), i.e., Savanopulex is characterised by an indistinct (weak) sublateral carinae on the metope ( Gnezdilov & Bourgoin 2009; fig. 25) and Issopulex gloriosus is characterised by a peculiar shagreen surface of the metope, coryphe, pro- and meso- notum (Gnezdiov 2014; figs.1, 3, 5, 7). We therefore tentatively place the new species in Calampocus noting that although the aedeagal hooks are similarly curved, the left aedeagal hook curves upwards rather than downwards and the lateral phallobase lobes are larger (as in Afronaso ) and lack denticles.
