New record of Blepharicnema splendens (Diptera, Calliphoridae, Luciliini) and range expansion in Caquetá, Colombia

ABSTRACT Blepharicnema splendens is a dipteran with occurrence restricted to the Neotropical Andean mountain forests from 1,400 to 2,500 masl. We surveyed the species using Van Someren-Rydon traps with decaying fish as bait in four sites (veredas) in the Eastern Cordillera, in the Municipality of Florencia, Caquetá, Colombia. A total of 221 individuals were collected in the four localities. The Vereda Las Brisas had the highest abundance, with 104 specimens (45.4%), followed by El Vergel, 76 (33.2%), Tarqui, 46 (20.1%) and Los Lirios, 2 (0.9%). The record of this species in the mountainous ecosystems of the Department of Caquetá expands the known distribution of B. splendens and adds to the incipient knowledge on the diversity of Diptera in this region.

摘要：亮睑丽蝇（Blepharicnema splendens）是一种双翅目昆虫（dipteran），其分布局限于海拔1400至2500米的新热带界安第斯山地森林。本研究以腐鱼为诱饵，采用范·索默伦-赖顿诱捕器（Van Someren-Rydon trap），对哥伦比亚卡克塔省佛罗伦萨市东科迪勒拉山脉的4个样点（veredas，哥伦比亚村级居住单元）中的该物种开展了调查采集。本次调查共在4个样点采集到221头该物种个体。其中拉斯布里萨斯样点（Vereda Las Brisas）的种群丰度最高，共采集到104头个体，占总采集量的45.4%；依次为埃尔韦赫尔样点（El Vergel）76头（33.2%）、塔尔基样点（Tarqui）46头（20.1%），洛斯里里奥斯样点（Los Lirios）仅采集到2头（0.9%）。本次在卡克塔省山地生态系统中发现该物种，不仅拓展了亮睑丽蝇的已知分布范围，还为该区域双翅目多样性的初步研究补充了新的科学资料。
