Data from: Cryptotermes colombianus a new drywood termite and distribution record of Cryptotermes in Colombia

A new species of drywood termite (Kalotermitidae), Cryptotermes colombianus, is described and new records for Cryptotermes cylindroceps and Cryptotermes mangoldi are presented from the Caribbean coast of Colombia. C. colombianus is described from two soldiers and genetic sequences. This unusual species differs noticeably from other regional Cryptotermes species for its weak and inconspicuous definition of the frontal and genal horns and its acute angle of the frons with respect to the vertex. C. colombianus clustered with species from the Ethiopian and Oriental region and it is closely related to Cryptotermes havilandi. C. cylindroceps is widely distributed along the Colombian Caribbean coast, commonly associated with dead wood in mangrove habitats. It also is commonly found in wooden furniture, constituting an important household pest. C. mangoldi is reported from the Caribbean mainland for the first time. With these new records, there are now five Cryptotermes species for Colombia, including the pest species Cryptotermes brevis and Cryptotermes dudleyi. This new description raises the numbers of Neotropical Cryptotermes to a total of 34 species, of which 2 are fossils, 4 introduced, and 28 endemic.本研究记述了木白蚁科（Kalotermitidae）下1个新的干木白蚁（drywood termite）物种——哥伦比亚堆砂白蚁（Cryptotermes colombianus），同时报道了在哥伦比亚加勒比海沿岸发现的圆柱头堆砂白蚁（Cryptotermes cylindroceps）与曼氏堆砂白蚁（Cryptotermes mangoldi）的新分布记录。哥伦比亚堆砂白蚁的记述基于2头兵蚁标本及遗传序列数据。该新种与该区域其他堆砂白蚁属（Cryptotermes）物种差异显著：其额角与颊角较弱且不明显，且额面与头顶夹角呈锐角。系统发育聚类分析显示，哥伦比亚堆砂白蚁与旧热带界（Ethiopian region）及东洋界（Oriental region）的堆砂白蚁属物种聚为一支，且与哈氏堆砂白蚁（Cryptotermes havilandi）亲缘关系密切。圆柱头堆砂白蚁广泛分布于哥伦比亚加勒比海沿岸，常栖息于红树林生境的枯木中，同时也频繁见于木制家具之中，是重要的居家害虫。曼氏堆砂白蚁为首次在加勒比海大陆沿岸被报道。加上本次新增的分布记录，哥伦比亚现已记录堆砂白蚁属物种5种，其中包括短头堆砂白蚁（Cryptotermes brevis）与达德利堆砂白蚁（Cryptotermes dudleyi）这两种重要害虫。本新种的记述使新热带界堆砂白蚁属物种总数达到34种，其中2种为化石物种、4种为外来引入物种，其余28种为特有物种。
