摘要

单型鳞羽Malkoha Lepidogrammus cumingi (Fraser 1839)和多型红冠Malkoha Dasylophus superciliosus (Dumont 1823)是菲律宾特有的两种杜鹃。这些地方性杜鹃的分类和分布鲜为人知。最近的分布数据显示,这些杜鹃在吕宋岛、卡坦多内斯岛和马林杜克岛的分布模式更广泛;然而,这些岛屿种群之间的形态变化仍然未知。虽然这两个物种都是单性的,但两性之间的差异主要是基于羽毛的颜色。超纤毛短尾蝗由两个亚种组成:短尾蝗。(吕宋岛南部)和ssp。cagayanensis(吕宋岛北部)。根据毛羽、胸毛颜色和尾带的差异,确定了两个亚种的分离。在本研究中,我们研究了(1)超纤毛毛鼠亚种之间的形态差异,(2)岛屿种群之间的形态差异,以及(3)两种马科哈的两性差异(两性二态性)。对184个博物馆标本进行了四项线性测量(喙长、翼长、跗骨长和尾长)。结果表明,卡坦杜内斯(Catanduanes)组(n=10)比Marinduque组(n=9)小。红冠马科哈(Malkoha D. superciliosus)在两个亚种间表现出显著差异。与ssp相比,Cagayanensis (n=28)的体型(喙长、翼长和尾长)较小。superciliosus (n = 81)。最后,根据分析的形态计量数据,本研究证实了这两个物种的性别是单态的。

Morphometric Variation in Lepidogrammus cumingi and Dasylophus superciliosus from Greater Luzon, Philippines based on Museum Specimens
The monotypic Scale-feathered Malkoha Lepidogrammus cumingi (Fraser 1839) and polytypic Red-crested Malkoha Dasylophus superciliosus (Dumont 1823) are two of the endemic cuckoos in the Philippines. The taxonomy and distribution of these endemic cuckoos are poorly known. Recent distribution data of these cuckoos showed broader distribution patterns in the islands of Luzon, Catanduanes, and Marinduque; however, morphometric variations among these island populations are still unknown. While both species are sexually monomorphic, the differences between sexes were mainly based on plumage coloration. Dasylophus superciliosus is composed of two subspecies: ssp. superciliosus (Southern Luzon) and ssp. cagayanensis (Northern Luzon). The separation of the two subspecies of D. superciliosus was determined by the differences in superciliary feather, the coloration of breast plumage, and the tail band. In this study, we investigated the morphometric variations (1) between subspecies of D. superciliosus, (2) among island populations, and (3) between sexes (sexual dimorphism) of the two malkoha species. Four linear measurements (bill length, wing length, tarsus length, and tail length) were measured from 184 museum specimens. Results showed that the Catanduanes group (n=10) of L. cumingi exhibited a smaller body size than the Marinduque group (n=9). Red-crested Malkoha D. superciliosus showed significant differences between its two subspecies where the ssp. cagayanensis (n=28) exhibited smaller body size (bill length, wing length, and tail length) compared to ssp. superciliosus (n=81). Lastly, this study confirms that the two malkoha species are sexually monomorphic based on the analyzed morphometric data.

期刊介绍: The Philippine Journal of Systematic Biology (Print ISSN: 1908-6865; Online ISSN: 2508-0342) is an annual, peer-reviewed journal in English that publishes high quality reports of original research and reviews in the field of Taxonomy & Systematics, Ecology and Conservation Biology. The PJSB is a CHED recognized journal under CHED CMO 50 series of 2017. It is also included in the Clavariate Analysis (formerly a subsidiary of Thomson Reuters) Master Journal List under Zoological Record, BIOSIS Previews and Biological Abstracts.The PJSB is the official publication of the Association of Systematic Biologists of the Philippines (SEC Registration: Association of Philippine Taxonomists, Inc.). The organization financially supports the journal and all its endeavors. The journal aims to build up quality information on animal, plant and microbial diversity in the Philippines. Articles dealing with original research or reviews in Zoological, Botanical or Microbial Systematics, Ecology and Conservation Biology are welcome. Authors are advised to consult a recent issue of PJSB for the current format and style. All manuscripts are reviewed by at least two qualified referees.
