Foreword: Last issue, we talked about the rhinoceros golden turtle, and this week we continue to talk about the rhinoceros golden turtle.
Today's protagonist is the tumor rhinoceros golden turtle, this genus of species may be familiar with more insect friends, the most common in the country is the tumor rhinoceros golden turtle, the rarer is the strong tumor rhinoceros golden turtle (the price is not cheap).
<h1 class = "pgc-h-arrow-right" > about the genus Trichogomphus</h1>
Basic overview: There are a total of 4 kinds of rhinoceros golden turtles in China: Mongolian rhinoceros golden turtle, Rong tumor rhinoceros golden turtle, strong tumor rhinoceros golden turtle and horse tumor rhinoceros golden turtle.
There are a total of 16 species of rhinoceros turtles worldwide (mainly concentrated in Southeast Asia, including Australia, India, etc.), and some of the Malay sad little pockets and tyrannosaur pockets that are more familiar to insect friends are also members of the genus Rhinoceros turtles.
Some neoplastic rhinoceros turtles
Core features: Most males of rhinoceros species have more developed head horns, as well as strong tumors on the dorsal plate of the forebreast, large individuals still look very handsome, and some females also have head horns (relatively small); another major feature is that artificial breeding and breeding is relatively difficult than the moth rhinoceros golden turtle mentioned in the previous period.
<h1 class="pgc-h-arrow-right" > Trichogomphus mongol </h1>
Overview: Widely distributed in China's South of the Yangtze River and Yunnan-Guichuan and other regions, overseas also includes Southeast Asia's Myanmar, India, Laos, Thailand, Cambodia and other neighboring countries, male insect body length of about 30 ~ 47mm (for reference only).
They can often be found at the roots of the host tree (hidden in the hole) or nearby (forest paths, etc.) during the outbreak season, adults will nibble on the roots of the tree to suck sap, and larvae usually feed on humus at the root of the host tree.
Features: The male rhinoceros has a well-developed head horn, the anterior width and back is narrow and curved backwards upwards, the anterior part of the anterior thorax dorsal plate is a slope, the posterior part presents a developed tumor process, the anterior edge of the end of the tumor process has a large protrusion, and there is a small protrusion on both sides of the edge of the dorsal plate of the large individual forethia; the elytra as a whole is smooth without incisions, and there are only a few incisions at the base of the elytra and the middle seam. The female has a simple head and is densely packed with thick incisions.
<h1 class= "pgc-h-arrow-right" > Trichogomphus rongi</h1>
Overview: Only distributed in Fujian, China, is also the latest discovered in China's nodule rhinoceros golden turtle (officially published in 2000), has been confused as a Mongolian tumor rhinoceros golden turtle, the body size is relatively small compared to other domestic tumor rhinoceros golden turtle, the male body length of about 36 ~ 44mm.
Specimens of rhinoceros turtle orthodon and sub-molds
Features: The appearance is very similar to that of the rhinoceros, except that the dots at the base of the elytra are slightly more distant than the base of the elytra. However, in order to distinguish more accurately from the Rhinoceros Turtle, it can only be distinguished by the shape of the lateral process of the genitals.
<h1 class = "pgc-h-arrow-right" > trichogomphus martabani</h1>
Overview: Distributed in Guangdong, Guangxi, Sichuan, Yunnan, Tibet and other provinces of China, as well as India, Myanmar, Vietnam, Sikkim and other neighboring countries, the male insect body length of about 35 ~ 56 mm, female worm about 30 ~ 45 mm. According to the actual collection records, the overall distribution range of the rhinoceros turtle is still relatively narrow, and there are only collection records in the southern border of Yunnan and the border area of southwest Guangxi.
Features: The overall black is shiny, and the ventral surface and leg joints are slightly reddish. The male has a folded head, the head horn is curved backwards and laterally flattened and relatively strong; the anterior part of the dorsal plate of the anterior thorax has a wide depression, the concave surface is obviously wrinkled except for the middle, the posterior half of the thorax has a distinctly raised tumor process, and there is a round blunt small horn process on each side of the end, and the large individual tumor process is huge and almost covers the small shield; the wing slit is more incisive, and there are deep longitudinal concaves with thick round notches on both sides, and a small number of fine notches on the outer edge.
The female has only a small, small neoplastic process on the head, with a curved lateral margin of the dorsal plate of the anterior thorax, sharp anterior lateral angles, and blunt posterior lateral horns.

Trichogomphus robustus
</h1>
Overview: Only distributed in China's Fujian, Guangxi, Yunnan, and Vietnam, wild adult insects often suck sap in the host tree hole, larvae also live in the tree hole to eat tree roots, male insects body length of about 34 ~ 51mm.
Note: There is no detailed origin information of the Fujian Rhinoceros Golden Turtle recorded in the literature earlier, and no specimens have been collected in China since then. However, in recent years, the Fujian insect circle has collected live rhinoceros turtles and larvae in Sanming, thus confirming the distribution in Fujian. At present, the habits of the strong rhinoceros turtle have been basically clarified, and artificial breeding can be realized (if you are interested, you can check the feeding article of Ah Yin).
Features: The male rhinoceros turtle has a long head horn and a tooth process on the posterior margin of the proximal end; the dorsal plate of the anterior thorax has two forward flaky chest horns (broad and stout), the thoracic horns are slightly forked at the end, and the central incoclinations in the two thoracic horns are concave; and the elytra are only slightly deeper in the posterior half of the lateral margin and the end of the elytra. Females are large in size with a pronounced depression in the forethia and a transverse ridge in the middle of the depression front.
