Morphology
Soldier
Head yellow or deep yellow, paler where the frons meets the vertex, the labrum deep yellow, the antennae yellow, the anterior half of the mandibles purplish brown and the posterior half becoming yellowish brown, the postmentum slightly darker than the rest of the head. Pilosity of the head medium in density, denser on the clypeus and frons; the anterior part of the postmentum with two to three long setae on each side. The apex of the labrum is narrowly rounded and does not reach the left marginal tooth. Mandibles slender and sickle-shaped, the apices slightly incurved; the tooth of the left mandible situated at nearly one-third of the anterior part with its apex slightly forwards; the right mandibular tooth very small, situated below the corresponding part of the left marginal tooth, with another indistinct granular small tooth near the base. Postmentum very broad and short, the sides of the posterior part nearly parallel, the posterior margin slightly contracted inwards and concave in a circular arc, the surface of the mentum rough. Antennae mostly with 16 segments, segment 2 slightly longer than segment 3, segment 4 the smallest, the terminal segment stout and nearly conical with a rather blunt tip. Pronotum saddle-shaped, the anterior lobe narrow and small, the posterior lobe broad and large, both the anterior and the posterior margin with a distinct median notch. The fore tibia is rather swollen; the hind tibia is about equal to or slightly shorter than the head width.
Alate
Dorsum of the head and the pronotum purplish brown, the pronotum with a pale T-shaped mark at the centre and a pale spot on each side near the anterior margin; the postclypeus yellowish brown, the anteclypeus greyish white; the mandibles dark brown along the marginal teeth and the periphery and brownish yellow at the base; the anterior half of the labrum reddish brown and darker than the posterior half, with a pale transverse band between them; the wings purplish brown. Pilosity of the head, thorax and abdomen medium in density; the base of the mandibles bears more than ten mandibular-base setae. Head nearly circular, the compound eyes rather small and nearly round, the ocelli round and slightly elongate; the fontanelle small, granular and projecting, situated at the centre of the line joining the posterior margins of the compound eyes; antennae with 19 segments, segment 2 about one and a half times the length of segment 3, segment 3 equal to or slightly longer than segment 4, the segments after the fifth almost equal, the terminal segment slightly larger and elongate-oval. Postclypeus slightly raised, its length slightly less than half its width, with a median longitudinal suture. Pronotum rather broad, its width about equal to or slightly less than the head width; the anterior margin shallowly V-shaped, without a distinct median notch; the posterior margin narrower and shallowly concave at the middle.
Worker
Two forms, large and small; the large form is slightly darker in body colour than the small form.
Nymph
Abstract (from the source)
Soldiers are yellow to deep yellow with a pear-shaped head, a very broad and short postmentum whose rear margin is concave, and slender sickle-like mandibles. The left mandible bears a tooth near the anterior third, the right only a minute one set lower. Most antennae have 16 segments. Alates are purple-brown with a pale T-shaped mark on the pronotum and pale spots at its front corners, 19 antennal segments, and the second segment 1.5 times the third.

- BIONOMICS OF ODONTOTERMES HAINANENSIS (LIGHT)
Abstract
Odontotermes hainanensis (Light) is an important insect pest damaging the dikes of reservoirs in South China. The present paper deals with the morphologies of the castes, behaviour during cultivation of the primary colonies in the laboratory and the activities of dispersal flight, foraging and nest building in the field.
- Termites of the Genus Odontotermes are Optionally Keratophagous
Abstract
In this study we tested experimentally whether the consumption of mammalian hooves by termites of the genus Odontotermes is a mere incidental, previously overlooked event, or whether higher termites frequently exploit hooves of ungulates as a supplementary food source. The experiment was conducted in the open woodland savanna region of Serengeti National Park, Tanzania. In total, 88 hooves of wildebeest (Connochaetes taurinus) and zebra (Equus burchelli) – of two age classes – were offered to the termites in the field. After five days, 18.3% of old and 15.0% of fresh wildebeest hooves and 16.7% of old zebra hooves were utilized by termites as a food source. Accordingly, we report here for the first time a systematic, frequent necrophorous foraging behavior of termites in general, which also adds termites to the very short list of potential decomposers of mammalian hooves. Termites of the genus Odontotermes seem not to show a preference for a specific age class of the provided wildebeest hooves. Our results suggest that ungulate hooves represent a spatially and temporarily highly variable, potentially macro- and micronutrient-rich, supplementary food source for higher termites in this savanna ecosystem. Termites of the genus Odontotermes might accordingly be considered as being not only decomposers, but also optional necrophores, i.e. being keratophagous. Members of this genus might play an important role in the decomposition of mammalian hooves in African savannas.
- Xylaria species associated with nests of Odontotermes formosanus in Taiwan
Abstract
Nine species of Xylaria were collected in Taiwan from nests of Odontotermes formosanus, the only known macrotermitine termite in Taiwan. These include six newly described species, X. acuminatilongissima, X. atrodivaricata, X. brunneovinosa, X. griseosepiacea, X. intraflava and X. ochraceostroma, and three previously known species, X. cirrata, X. escharoidea and X. nigripes. We obtained cultures and ITS sequences from the nine species found in Taiwan and describe anamorphs for eight of them. Before the current study teleomorphanamorph connections in the Xylaria species associated with termite nests have been established unequivocally in X. escharoidea only. Xylaria angulosa, X. fimbriata, X. kedahae, X. micrura, X. radicans, X. reinkingii and X. tolosa also are considered and annotated because they were reported to grow on ground and likely are associated with termite nests. Epitypifications are made for X. cirrata, X. escharoidea and X. nigripes. Xylaria sanchezii is considered a nomen dubium. Photographs are presented for most of the aforementioned species. A dichotomous key to 25 Xylaria species growing on termite nests or ground also is given.
