Abstract

Two new Coecobrya species, which were newly collected in 2014, are described from China. Coecobrya
sanmingensis sp. n. from southeast China (Fujian) is the fourth 1+1 eyed species in the genus; it can be
distinguished from other three species by the ciliate chaetae X and X, , on the ventral side of head, the
abundant chaetae on the trochanteral organ, a large outer tooth on the unguiculus, the absence of smooth
manubrial chaetae, and the dorsal chaetotaxy. Coecobrya ginae sp. n. from southwest China (Yunnan) is
characterized by paddle-like S-chaetae of Ant. III organ, ciliate chaetae X, X, and X, posterior to labium,
medial macrochaetae on the mesothorax, and 5+5 central and 2+2 lateral macrochaetae on the fourth

abdominal segment. An updated key to the Chinese species of Coecobrya is given.

Introduction

Deharveng (1990), Chen and Christiansen (1997) and Zhang et al. (2009, 201 1a)
made great contributions to the modern taxonomy of the genus Coecobrya. Its mem-
bers have plurichaetotic chaetotaxy, no labral papillae, an inverted intrusion on the

labral margin which is U-shaped, labial chaetae MELL always smooth, reduced eye
number (0 to 3 eyes per side), pigment reduced or absent, antennal apical bulb absent,
falcate mucro with a basal spine, tenaculum with 4+4 teeth and one large striate chaeta,
and scales and dental spines absent (Zhang et al. 2009). The genus is worldwide and
very abundant in Southeast and East Asia. So far, about approximately one quarter
(12/47) of species have been reported from China. Five of them were discovered dur-
ing recent expeditions in this country (Xu et al. 2012; Zhang and Dong 2014). Here,
two new species, collected in 2014, are described from southern China. An updated
key to the Chinese species of Coecobrya is also given.

Materials and methods

Specimens were cleared in Nesbitt’s fluid, mounted under a coverslip in Marc André
II solution, and studied using a Nikon E80i microscope. Photographs were enhanced
with Photoshop CS5. ‘The labial chaetae terminology follows Gisin’s system (1967).
The dorsal and ventral chaetotaxy of head and the Ant. III organ are described after
Chen and Christiansen (1993). Dorsal body chaetae are designated following Szeptycki
(1979) and Zhang et al. (2011b). The number of macrochaetae is given by half-tergite
in the descriptions (left side of tergites drawn in figures). Tergal S-chaetotaxic formula
follows Zhang and Deharveng (2014). Type material is deposited in the collections
of the Department of Entomology, College of Plant Protection, Nanjing Agricultural
University (NJAU), P. R. China.
