Abstract

A new species, Odontorrhina maraisi sp. n., is added to the genus on the basis of new material collected in the semiarid Namaqualand region of South Africa. A new subspecies of O. pubescens (Olivier, 1789), O. pubescens hantam ssp. n., is recognized from the high altitudes of the Hantamsberg near Calvinia. Recent observations have led to the conclusion that all members of the genus, with the exception of O. krigei Schein, 1950, complete their larval development under dense shrubs, utilizing mainly leaf litter as food source and the shade provided by the host plant as protection against heat and desiccation. O. krigei makes use of termite hills to achieve the same, while feeding on detrital matter produced by termites. The coastal O. pubescens s. str. appears to be the only member that has feeding adults, which are able to ingest sap of Melianthus spp. shrubs after cutting the bark of the softest branches in the upper part of the plant canopy.

INTRODUCTION

The genus Odontorrhina Burmeister, 1842, seems to be restricted to the Northern and Western Cape provinces of South Africa, although there is an old but unconfirmed record for O. pubescens (Olivier, 1789) in southern Namibia (near Grünau: Holm & Marais 1992). The genus is of special conservation importance in that it is endemic to the winter rainfall area of the Cape region and species are generally restricted to the Fynbos and Succulent Karoo biomes (Mucina & Rutherford 2006). They are therefore potentially under threat, should climate change in this area escalate towards worst-case scenarios (Co+Life 2011).

Recent investigations in areas previously neglected or poorly sampled have provided material and information for a taxonomic revision of the genus, involving the erection of a new species and a new subspecies, as well as provision of the first account of the habitat of larval stages of members of the genus. Knowledge of the ecology of the adult stage for all five taxa has also been enhanced through direct observations made both in their natural environment and in captivity.

TAXONOMY

Genus Odontorrhina Burmeister, 1842

  • Odontorrhina: Burmeister 1842: 396; Lacordaire 1856: 522, 528; Schoch 1894: 215; Péringuey 1907: 327, 363; Schenkung 1921: 302; Marais & Holm 1989: 13; Holm & Marais 1992: 120; Rigout & Allard 1992: 59; Sakai & Nagai 1998: 303.

  • Type species: Cetonia pubescens Olivier, 1789, by subsequent designation (Marais & Holm 1989).

  • Diagnosis: Apart from an unconfirmed record of O. pubescens in southern Namibia (Marais & Holm 1989; Holm & Marais 1992), all species of the genus appear to be restricted to the Western and Northern Cape provinces of South Africa. According to Holm and Marais (1992), the genus may be most closely related to Trichostetha Burmeister, 1842, which also exhibits the bulk of its taxonomic diversity in the Cape provinces and, more specifically, the Cape Floral Region. The two genera also share a heavily setose body and a variably developed white band on the lateral pronotal margins. Odontorrhina is, however, unique in having two pointed and upturned denticles on the anterior margin of the clypeus. It differs further from Trichostetha by exhibiting elytra that are invariably without any cretaceous spots and a metallic sheen, both on the dorsal and ventral sides (the latter character is absent in O. krigei Schein, 1950).

  • Key to the species and subspecies of Odontorrhina

    1 Elytral costae poorly developed or absent; body setae white 2

    — Elytron with 3 prominent costae; body setae yellow, black or brick-red 4

    2 Dorsal surface dark bronze, with white marks on pronotal sides and pygidium residual or absent; ventral surface olive green to shiny bronze maraisi sp. n.

    — Dorsal surface metallic green to coppery, with white marks on pronotal sides and pygidium; ventral surface shiny metallic green to coppery 3

    3 White marks prominent, elytral setae thin and long, anterior pronotal margin obtuse pubescens pubescens (Olivier, 1789)

    — White pronotal lines reduced and generally interrupted towards base, elytral setae thick and short, anterior pronotal margin rounded pubescens hantam ssp. n.

    — 4 Body surface and setae completely black (exceptionally setae also brown to yellow), with occasional white marks on pronotal sides krigei Schein, 1950

    — Body surface light bronze, with occasional white marks on pronotal sides and pygidium; setae yellow hispida (Olivier, 1789)

    Figs 1, 2, 5

  • Etymology: The species is named after Andre P. Marais of Cape Town, who pioneered observations on the species in the interior region of Namaqualand.

  • Diagnosis: O. maraisi is essentially an intermediate form between O. hispida and O. pubescens. It shares several adult biological characteristics with O. hispida (see below), but can easily be separated from it because it has white instead of yellow setae, poorly developed elytral costae, and the anteroclypeal margin simply bidentate. Moreover, the dorsal side is much darker and the body size smaller than in the latter. O. maraisi can equally easily be distinguished from O. pubescens by its much darker colour and generally smaller size, its drastically reduced or absent white tomentum bands (pronotum), and by the presence of stripes (sternites) and spots (pygidium) (Figs 1, 5, 7). Additional characters differentiating the two species include: (a) small and sharply upturned clypeal teeth in O. maraisi, which are larger and smoothly curved in O. pubescens; (b) frons with dense tuft of long setae projecting forward in O. maraisi but reduced or absent in O. pubescens; (c) well delimited, unsculptured medial band on scutellum of O. maraisi, but poorly defined in O. pubescens; (d) elytral costae poorly developed in O. maraisi, but absent in O. pubescens (Figs 1, 5, 7); (e) metatibia with simple denticles in O. maraisi, but distal denticle blade-like to bifurcate in O. pubescens; and (f) aedeagal lobes shorter and more compact in O. maraisi (Fig. 2) than in O. pubescens.Description:

    Figs 3, 4

  • Etymology: This subspecies is named after the Hantam Plateau in the Hantamsberg mountains of the Northern Cape Province, where the type series was collected.

  • Diagnosis: The shape of the anterolateral margin of the pronotum is much rounder in O. p. hantam (Fig. 3a) than in the nominal subspecies, where a virtually obtuse angle is to be seen (Fig. 7). Also, the white band along the lateral margin is thinner and limited to the anterior 2/3–1/2 of the pronotal sides in O. p. hantam (Fig. 3a), whereas it is generally wider and complete in O. p. pubescens (Fig. 7). The other areas of white marking are also drastically reduced in O. p. hantam, with the ventral side in particular exhibiting hardly any of the cretaceous bands (Fig. 3b) that are so prominent on the femora and abdominal sternites of the nominal subspecies. The setae on the elytral surface of O. p. hantam are less dense, shorter and thicker than in O. p. pubescens. Finally, the typical metallic green sheen of the nominal subspecies appears to be replaced by a darker, bronze to coppery sheen in O. p. hantam (Fig. 3a). The male genitalia are very similar in the two subspecies, but the dorsal lobes of the parameres appear to be broader at the apex in O. p. hantam (Fig. 4) than in O. p. pubescens (cf. Holm & Marais 1992, fig. 61a, b).

  • Description:

  • Size. Length 21.4–25.0 mm, width 12.2–13.1 mm (n = 4).

  • Holotype: ♂ SOUTH AFRICA: Northern Cape: Calvinia, Hantamsberg [31°25′S 19°50′E], 15.xii.1995, A.P. Marais (SAMC).

  • Paratypes: SOUTH AFRICA: 2 ♂ same data as holotype (PCRP, PCMB); 1 ♂ same data but 9.ii.1996 (PCBM); 1 ♂ same data, emerged [in Cape Town], 17.iii.1996, A.P. & M.E. Marais (PCRP); 2 ♂ 1 ♀ same data but 23.iii.1996 (2♂ PCBM, 1♀PCRP).

  • Remarks: O. pubescens hantam appears to be restricted to the high altitudes ( >1400 m) of the Dolerite Renosterveld bioregion in the interior part of the Northern Cape Province (Hantam Plateau). On the other hand, O. p. pubescens is found along the Western and Northern Cape coast, in the Western Strandveld and the Namaqualand Hardeveld and Sandveld bioregions, from sea level to about 500 m.

    DISCUSSION

    The genus Odontorrhina is a Cape endemic, restricted to the Fynbos and Succulent Karoo biomes (Mucina & Rutherford 2006). The newly described O. maraisi inhabits the Namaqualand Granite Renosterveld bioregion and, together with O. pubescens hantam, appears to be isolated and adapted to a highly specialized habitat (Fig. 6). Conversely, all the other members of the genus are quite widely distributed in the region. While O. p. pubescens occurs through most of the South African Atlantic coastal belt, at or near sea level, from at least Bloubergstrand in the south to Port Nolloth in the north (Fig. 6), the other two species, i.e. O. hispida and O. krigei, are typically montane and generally occupy the most inland portion of the range of the genus (Fig. 6). O. hispida occurs further to the east than any other member of the genus, having been recorded at least as far as Komsberg in the Northern Cape Province (A.K. Brinkman, specimen data label) and Calitzdorp in the Western Cape Province (J.B. Ball, specimen data label). Its habitat includes parts of the Shale Renosterveld and the Granite & Sandstone Fynbos bioregions. Although there appear to be no recent records from the Cape Town area, the species has repeatedly been collected there in the past, probably at the highest altitudes on Table Mountain and at other major elevations in the Cape Peninsula (e.g. Lions Head, specimen data label) (Fig. 6). O. krigei appears to be restricted to a smaller region in the Western Cape mountain Sandstone Fynbos, from Jonaskop above Villierdorp in the south, to Van Rhynapos;s Pass in the north (Fig. 6).

    Regarding seasonality of adult activity, the genus is essentially restricted to the winter rainfall region of South Africa and its members fly mostly during late winter and spring, i.e. at the end of the wettest and coldest part of the year. While O. maraisi has so far been recorded only in September and October, most of the records for O. p. pubescens are from September (49%), followed by August (26%) and October (25 %), with very few in November (0.05 %) and only one in July. O. p. hantam, on the other hand, has so far only been recorded during summer, from December to March, indicating potential seasonal segregation between the two subspecies in respect of adult activity. Like O. p. pubescens, O. hispida also appears to fly preferentially during the spring months, particularly in October (59% of records) and September (24% of records), but also exhibits a secondary period of activity in autumn, with about 10 % of records in March and April. Finally, O. krigei exhibits the longest period of adult activity, from July to May, with most records being for January (22%), November (15%), and August, October and March (all at 11 %).

    f06_733.jpg

    The adult feeding biology of the genus has only partially been investigated. O. p. pubescens is the only member of the genus that has been observed feeding on the sap of Melianthus spp. shrubs (Fig. 7). At least three species of this plant genus are known to be utilized by O. p. pubescens for this purpose: M. major (Holm & Marais 1992), M. elongatus and M. comosus (pers. observ). Adults of O. pubescens have also been collected on flowers on at least one occasion (Endrödy-Younga, specimen data label), and observed flying around flowering Leucodendron pubescens plants (S.K. & R.W. Gess, specimen data label). This may indicate a limited ability on the part of the species to utilize nutrition directly from flower nectar, in addition to Melianthus sap.

    Conversely, O. maraisi, O. hispida and possibly also O. p. hantam do not appear to feed on either flowers or sap and fly regularly during sunny days, even after the soil has become completely desiccated following a rainfall event. Indeed, it has not yet been established whether adults emerge from their underground cocoons only after major rains (moisture cue), or at a particular and fixed time of the spring season (photoperiod/ thermal cue). All adults of these species collected thus far were active during the hottest hours of the day, from about 10:30 to about 14:30. This is in contrast to the pattern of activity exhibited by the coastal species, O. p. pubescens, which is generally observed flying from about 9:00 until about 16:00–17:00. The difference may be related to the ability of the latter to regularly resupply its energy reserves by feeding on Melianthus sap and, therefore, spend more time flying around to search for mates and for suitable places to lay eggs. Conversely, O. maraisi, O. hispida and O. p. hantam may, in the absence of a suitable/reliable food source, be forced to restrict their daily window of activity in order to save energy and maximise reproductive output.

    f07_733.jpg

    All records for O. krigei indicate that this species also does not feed in the adult stage and that it flies only occasionally, generally spending most of its time hidden under or within termite mounds (A.P. Marais pers. comm.). No evidence could be found to support the claim that “adults of both O. hispida and O. pubescens have been collected under dry cattle dung and near cattle enclosures”, as reported earlier (Marais & Holm 1989; Holm & Marais 1992).

    Their larval development also does not appear to depend on dry bovine dung, but rather on decaying leaf litter accumulated under a variety of shrub species or, in the case of O. krigei, on the detrital material deposited in nests of blackmound termites, Amitermes hastatus (Marais & Holm 1989; A.P. Marais pers. comm.). Larvae of O. hispida have repeatedly been found under shrubs of unidentified Rhamnaceae and/or Asteraceae species at Sutherland and were bred successfully in captivity using only leaf litter of these plants as food source (pers. observ). Similarly, A.P. Marais (pers. comm.) reared O. pubescens larvae collected in the Hantamsberg on dead plant matter found underneath unidentified bushes. He also found larvae of this species within dung middens of Klipspringer, Oreotragus oreotragus. While no larval stages of O. maraisi have been observed and/or bred to date, a female was seen landing on a koringbos shrub, Anthospermum spathulatum s. str., at Witwater (Fig. 5), indicating the possibility that again its larval development may take place at the base of large but short shrubs. This seems plausible, as such shrubs will not only provide food for the larvae, but also protect them from desiccation and the extreme temperatures that the soil experiences in these semiarid regions, particularly during the hottest part of the summer.

    f08_733.jpg

    While little is known about the predators of Odontorrhina in general, O. maraisi was observed to be heavily predated upon by the social spider Stegodyphus dumicola, which spreads its silk sheets in a very effective, vertical v-shaped web from a central nest made of hard silk incorporating prey remains and pieces of vegetation (Fig. 8). There are up to several dozen spiders in one of these community nests, and as soon as anything that moves becomes entangled in the web, some of them rush out to overpower and immobilize the potential prey. At Witwater (the type locality for the species) in early October 2010, more than 20 adult O. maraisi were found trapped in various webs of S. dumicola on a single day. They were in various stages of consumption, but all were relatively fresh and some still alive (Fig. 8).
