Ochicanthon loebli Paulian
No full textOchicanthon loebli (Paulian) (Figs. 31–35) Phacosoma loebli Paulian, 1983: 58. Description. Body (Fig. 31) predominantly dark brown with a light green metallic shine. Punctation on dorsal surface of head consisting of simple setiferous punctures separated by interval of about two times their diameter. Pronotum in lateral view weakly convex, outline at base almost in line with that of elytral suture; laterobasal paramarginal ridge absent. Pronotal punctation (Fig. 32) similar to that on head, but finer and sparser; setae almost indistinct, straight and recumbent. Elytra in lateral view moderately convex; suture not raised; striae shallow, narrow, consisting of long straight sulci without depressions (Fig. 32); interstriae fairly flat, very finely and unevenly punctate; setae very fine, straight and recumbent; background microsculpture smooth; lateral ridge posteriorly extended to level of apex of third stria. Mesosternum impunctate; meso-metasternal line angulate in the middle; metasternal shield with even, fine sparse punctures (Fig. 33). Pygidium fairly smooth, scarcely covered with very fine setiferous punctures. Protrochanter with outer margin arcuate. Hind wings absent. Male lacking obvious secondary sexual characters. Aedeagus as in Figs 34–35. Measurements (mm; n = 4): TL = 3.8–4.4; BW = 2.1 –2,6; PL = 1.2–1.3; PW = 2.0– 2.3; EL = 2.1–2.4. Material examined. Holotype (male, MHNG): “ India, Madras, Palni Hills, 10 km NW Kodaikanal, 2150m, 15.xi. 1972, leg. Besuchet, Löbl & Mussard, # 27 ” [sifting at forest edge with ferns and Rhododendron, near a river]. Additional material (3, MHNG): “ India, Madras, Palni Hills, Kodaikanal, 2200m, 12.xi. 1972, # 23 ” [sifting in degraded forest with Rhododendron], 2 males and 1 female. Distribution and natural history. South India (Kodaikanal, in the South Western Ghats montane rain forest ecoregion). Diagnosis. Presence of elytral striae consisting of long straight sulci without depressions is unique to O loebli. The close proximity of two distinctly different wingless species (O. devagiriensis and O. loebli) in nearby mountain peaks in the South Western Ghats montane rain forest ecoregion point towards local endemism and isolation in the montane habitats. See diagnosis under O. besucheti.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on pages 13-14, DOI: 10.5281/zenodo.27662

Distribution and natural history. Northeast India (Cherrapunjee, in the Meghalaya subtropical forests ecoregion). Diagnosis. Ochicanthon deplanatus is the only species of the Indian subcontinent to have each elytron with 2 orange-yellow spots and coriaceous elytral background microsculpture. These characters are shared with O. obscurus recorded from the eastern boundary of Arunachal Pradesh and beyond the northeast of the Indian subcontinent in Myanmar, Laos, Vietnam and Thailand (Boucomont 1920, Hanboonsong & Masumoto 2001, Sewak 2006), but O. deplanatus has the pronotum unicolored unlike O. obscurus with anterolateral lobes of pronotum orange-yellow.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on page 7, DOI: 10.5281/zenodo.27662

Paratypes (3, MHNG): Same data as holotype, 1 male and 1 female; “ India, Meghalaya, Khasi hills, Shillong Peak, 1800m, 21.x. 2000 , leg. Carlton, Cuccodoro, Erne & Leschen, # 9 a” [sifting leaf litter in mixed Pine forest], 1 female. Distribution and natural history. North East India (Upper montane forest in Shillong Peak in the Meghalaya subtropical forests ecoregion ). Etymology. Named after Claude Besuchet, Geneva, who collected part of the type series. Diagnosis. Among the four wingless species of Ochicanthon (O. besucheti, O. devagiriensis, O. loebli and O. vazdemelloi) in the Indian subcontinent, O. besucheti and O. loebli possess elytral interstriae with annular setiferous punctures not arranged in two rows. It is the only wingless Ochicanthon recorded from northeast of the Indian subcontinent. Ochicanthon besucheti strongly resembles O. ernei and O. tristoides, from northeast India, but is easily distinguishable by the absence of wings, aedeagal shape and coarsely punctate central area of the metasternal shield.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on page 3, DOI: 10.5281/zenodo.27662

Paratypes (2 females, MHNG): same data as holotype. Distribution and natural history. Sri Lanka. (Peradeniya in the Sri Lanka lowland rainforest ecoregion). Etymology. Named after “ Ceylon ”, the former name of Sri Lanka. Diagnosis. Ochicanthon ceylonicus and O. cingalensis are the only Ochicanthon known from Sri Lanka. Both species can be easily distinguished by the pygidium, which is markedly punctate in O. ceylonicus and appearing impunctate in O. cingalensis. They uniquely share unicolored elytra and striae consisting of chains of oval depressions joined by straight sulci with the South Indian species O. gauricola and O. tristis. However the South Indian species have the middle portion of the meso-metasternal line subangulate.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on pages 3-6, DOI: 10.5281/zenodo.27662

Dorsal surface of head glabrous, with annular punctation separated by intervals approximately equal to their diameter. Pronotum in lateral view strongly convex, outline at base obtusely angled with that of elytral suture; laterobasal paramarginal ridge absent. Pronotal punctation (Fig. 14) consists of annular setiferous punctures separated by interval approximately equal to their diameter, becoming larger laterally and posteriorly; setae conspicuous, arcuate and semi-erect. Elytra in lateral view strongly convex, bearing about a dozen tubercles, some on posterior portion of disc projecting conspicuously; suture conspicuously raised, except on apical quarter; striae shallow, wide, consisting of chains of discoidal depressions joined by straight sulci (Fig. 14); interstriae moderately convex, uneven, covered with fine, sparse setiferous punctures arranged in two rows; background microsculpture smooth; setae stout, arcuate and semi-erect, never scale-like; lateral ridge posteriorly extended to level of apex of second stria.

IX. 2007, Shiju, T.R.” Paratypes (26): Same data as holotype, 15 females in SJC and ZSI-Ca; same data as holotype, but 2.

South India (upper montane evergreen forests at Eravikulam National Park, in the South Western Ghats montane rain forest ecoregion). Etymology. Named after the local name ‘Devagiri’ of St. Joseph’s College, Calicut, Kerala State, India. Diagnosis. Within the genus, the presence of projecting tubercles on elytral disc is unique to O. devagiriensis. Among the four wingless Indian species of Ochicanthon (see diagnosis under O. besucheti), only O. devagiriensis and O. vazdemelloi have the elytral pubescence arcuate, semi-erect and arranged in rows. The only other Ochicanthon species to possess erect elytral pubescence arranged in rows is O. hanskii Krikken & Huijbregts, 2007, from Borneo, which is interestingly also the only non-Indian wingless species of the genus.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on pages 7-10, DOI: 10.5281/zenodo.27662
