摘要

C对于许多其他爬行动物分类群来说,盲肠分类学可能具有挑战性。缺乏四肢,发育良好的眼睛和尾巴限制了分类特征的数量,科学收藏中许多盲肠物种的相对罕见限制了对变异的理解。因此,人们有时对物种界限知之甚少。分类学上的不确定性是IUCN红色名录中许多盲肠物种保护状况数据不足的主要原因。盲肠物种Caecilia pressula Taylor,1968是Taylor(1968)在其盲肠分类学修订中描述的1758年新热带Caecili Linnaeus的13个物种之一。C.pressula的描述基于美国自然历史博物馆(AMNH 4947049076)收藏的七个标本,这些标本是R.Snedigar于1938年在TerryHolden探险期间从圭亚那的Marudi山脉收集的(htt ps://siarchives.si.edu/collections/auth_exp_fbr_eace0098)。一只成年雄性AMNH A-49475被指定为正模,六个小得多、毫无疑问年轻得多的标本被指定为副模。这些标本先前被Dunn(1942)和Parker&Dunn(1964)认为是其模式种的标本https://doi.org/10.33256/hj30.4.227229

Taxonomic status of the Guyanese endemic caecilian Caecilia pressula Taylor, 1968 (Amphibia: Gymnophiona: Caeciliidae)
C to many other herpetological taxa, caecilian taxonomy can be challenging. Lack of limbs, and of well-developed eyes and tails limits the number of taxonomic characters, and the relative rarity of many caecilian species in scientific collections limits understanding of variation. Consequently, species limits are sometimes poorly understood. Taxonomic uncertainty is a major reason given for the data deficient conservation status of many caecilian species in the IUCN red list. The caecilian species Caecilia pressula Taylor, 1968 is one of 13 species of the Neotropical Caecilia Linnaeus, 1758 described by Taylor (1968) in his revision of caecilian taxonomy. The description of C. pressula was based on seven specimens in the collections of the American Museum of Natural History (AMNH 4947049076) that were collected from the Marudi Mountains of Guyana by R. Snedigar in 1938 during the TerryHolden Expedition (htt ps://siarchives.si.edu/collections/ auth_exp_fbr_eace0098). A single adult male, AMNH A-49475, was designated the holotype and six much smaller and no doubt much younger specimens were designated as paratypes. These specimens were previously considered by Dunn (1942) and Parker & Dunn (1964) to be specimens of the type species of its https://doi.org/10.33256/hj30.4.227229
