genus Protohermes van der Weele, 1907 (Megaloptera: Corydalidae: Corydalinae)
is the most species-rich group in the order Megaloptera with 89 species of the
genus being known. The genus is mainly distributed in the Oriental region (87
spp.), and two species are distributed in the Palaearctic region (Martins et
al. 2022). Adult Protohermes are morphologically characterized by the forewing
with anterior branch of A2 vein partly fused with stem of A1 vein, and the
presence of yellow or white round markings on wings in most species (Yang &
Liu 2010). Thailand is one of the most interesting regions for discovery of
megalopterans, because it is a biodiversity hotspot due to its rich diversity
and high endemism (Myers et al. 2000; Plant 2014; The Sustainability Consortium
WRI 2019). The country is composed of Indochina and Sundaic subregions, which
has been described as a zoogeographical crossroads or natural gateway from
North to South (Luangjame et al. 1997). Recently, 21 species of Megaloptera
were recorded in Thailand (Piraonapicha et al. 2021a). The previously reported
Megaloptera fauna of Thailand includes five unidentified Protohermes and two
named species: Protohermes furcatus Liu, Hayashi & Yang, 2008 from Chiang
Mai Province, and Protohermes triangulatus Liu, Hayashi & Yang, 2007 from
Chiang Rai, Chiang Mai, Nan Provinces (see also Liu et al. 2008, 2009;
Piraonapicha et al. 2021a). Protohermes stigmosus Liu, Hayashi & Yang, 2007
was previously known only from the type locality (Xishuangbanna, Yunnan
Province, China) by a single male (Liu et al. 2007). The species was classified
into the Protohermes costalis species group because it has widely separated
ocelli and a subcylindrical male ectoproct bearing a ventral tuft (Liu et al.
2007). Our recent survey of Megaloptera from Bo Kluea District, Nan Province in
northern Thailand found an interesting species of Protohermes. Having carefully
compared the specimens of this species with the type material of closely
related species, we concluded that this species is P. stigmosus, a new species
record from Thailand. We used the standard DNA barcode from the mitochondrial
COI gene to associate the male and female of this species successfully. The
barcoding regions of related species with P. stigmosus i.e. P. triangulatus and
P. furcatus were also sequenced to construct the tree. All examined non-type
materials are deposited in the Thailand Natural History Museum of the National
Science Museum, Pathum Thani (THNHM). In the present paper, the adult male is
redescribed based on Thai specimen, and female of the species is described for
the first time.
