Comments on synonymy.

The type material of all five taxa involved have been studied and compared (except holotype of Laccophilus vitshumbii ; not found). Minor variation in shape of penis apex and dorsal colour pattern can be recognized. There are, however, a series of transitional morphs between the extremes both regarding genitalia and external appearance. Distribution covers extensive areas of Africa south of Sahara which justifies occurrence of minor morphological variation within a species. No clear morphological evidence and distributional pattern are thus present which would merit separation of species or subspecies. Accordingly earlier synonymy of Laccophilus adspersus and Laccophilus livens is confirmed. Furthermore Laccophilus vitshumbii , Laccophilus adspersus nigeriensis and Laccophilus adspersus sudanensis are all considered new synonyms of Laccophilus adsperus . Laccophilus adsperus being the oldest available name is the valid name of the species.

Diagnosis.

Despite slight variation in shape of penis apex and elytra colour pattern in Laccophilus adspersus these features are still the best way of separation the species from other Laccophilus species. Laccophilus adspersus resembles most of Laccophilus olsoufieffi . Further study may show that they are also conspecific (see diagnosis of Laccophilus olsoufieffi on p. 106).

Description.

Body length 3.6-4.2 mm, width 1.9-2.2 mm. Body almost unicoloured pale ferrugineous to ferrugineous; elytra with slightly indistinct irrorations. At base irrorations slightly sparser and often slightly reduced. Some specimens exhibit a variable pale spot with reduced irrorations posteriorly on each elytron (Fig. 419).

Head: Pale ferrugineous. Slightly mat to rather shiny, finely microsculptured; reticulation indistinctly double. Large meshes contain 2-6 fine meshes. Almost impunctate. At eyes with some scattered, fine punctures.

Pronotum: Pale ferrugineous. Rather shiny, although finely microsculptured; reticulation double. Finer meshes sometimes indistinct and hardly discernible. When discernible large meshes contain 2-8 finer meshes. Almost impunctate; punctures indistinct and hardly visible. Scattered punctures may be discerned laterally and at anterior margin.

Elytra: Pale ferrugineous. With ferrugineous to dark ferrugineous, slightly obsolete irrorations. Sometimes each elytron posterior to middle with a pale spot where irrorations reduced (Fig. 419). Rather shiny, although densely microsculptured. Reticulation double; laterally and posteriorly double reticulation becomes indistinct. Large meshes contain generally 3-8 fine meshes. Fine meshes in part weakly developed and difficult to discern. Discal, dorsolateral and lateral rows of punctures, irregular, very fine and in part hardly visible. Pre-apical furrow fine, sparsely pubescent.

Ventral aspect: Pale ferrugineous to ferrugineous. Almost impunctate. Rather shiny although very finely microsculptured. Metacoxal plates with in part reduced transverse furrows. Abdomen basally with sparse, somewhat curved striae. Apex of prosternal process slender and pointed. Apical ventrite with a small knob on one side (Fig. 69).

Legs: Pro- and mesotarsus slender, somewhat extended, provided with suckers.

Male genitalia: Note variation in shape of penis apex; extreme apex exhibits a gradual change from pointing straight forwards to, being somewhat curved and blunt (Figs 261-264).

Female: Externally as male but apical ventrite lacks asymmetric knob (Fig. 70). Additionally pro- and mesotarsus slender.

Distribution.

Sudan, Ethiopia, Ivory Coast, Nigeria, Cameroon, Central African Republic, Zaire, Uganda, Kenya, Tanzania, Angola, Zambia, Malawi, Zimbabwe, Namibia, Botswana, South Africa, Swaziland (Fig. 544). Confusion in species delimitation has been common during the years and accordingly only personally verified records are accepted in the map.

Collecting circumstances.

Insufficiently documented. Van Vondel (2005) reports the species to be sampled in a pond surrounded by tree, bottom covered with plant remains and water lily growths. Furthermore collected from pools with water lily and Pistia stratiotes and in stagnant remain of brooklet. Nilsson and Persson (1993) report Laccophilus vitshumbii collected at light, in temporary ponds in almost dry stream (1450-2350 m a.s.l.). Omer-Cooper (1931) recorded the species in high altitudes (5500-7500 ft). Additional information may be gathered from the literature, e.g. Bilardo and Rocchi (1987) and Pederzani (1988). Often collected at light and with light traps.
