“…Although Thiotrichinae are known to utilize plants of ten families (all in eurosids), the host range of each species is usually restricted to one genus or a few related genera (Kuroko 1957; Sattler 1982; Huemer 1993; Omelko 1993; Oku 2003; Ueda and Fujiwara 2005; Kaiser et al 2008; Fujita et al 2009; Ueda 2011, 2013). Therefore, the host utilization of Thiotricha elaeocarpiella is unusual for this subfamily.…”

“…Another species, T. pancratiastis , known as a foliage feeder (leaf miner) of Morella rubra (Myricaceae), is also reported as a seed predator; the larvae of this species bore into the fruit and, after hollowing it out, utilize it as a portable case. This species probably has two generations annually in Honshu and more in the Ryukyus (Fujita et al 2009; Ueda 2011, 2013; as Polyhymno pancratiastis ).…”

A part of Japanese species of the genus Thiotricha Meyrick, 1886 are reviewed. Three species described by Omelko (1984) in the genus Cnaphostola Meyrick, 1918 are placed in combination with Thiotricha; Thiotricha biformis, T. angustellacomb. nov. and T. venustaliscomb. nov. These species are redescribed, and two new species, T. elaeocarpiella Kyaw, Yagi & Hirowatari, sp. nov. and T. flavitermina Kyaw, Yagi & Hirowatari, sp. nov. are described based on external morphological characters of adults and genitalia of males and females. Thiotricha chujaensis (Park, 2016), comb. nov. described in Cnaphostola from Korea, is newly recorded in Japan feeding on Mallotus japonica (Euphorbiaceae). One of the new species, T. elaeocarpiellasp. nov. has been associated with two different plants, Elaeocarpus zollingeri (Elaeocarpaceae) and Rhaphiolepis indica (Rosaceae). This paper presents the ﬁrst comprehensive description of the morphology, pupal morphology and biology of species previously treated in the genus Cnaphostola and their relatives in Japan.

“…Since then, the taxonomic status of the two genera has been treated differently by many authors. Some followed Moriuti (1982) (Park & Ponomarenko, 2006; Ponomarenko, 2008, 2019; Omelko & Omelko, 2011; Sakamaki, 2013), but some accepted the old classification system (Kaila et al ., 2001; Li, 2002; Ueda & Fujiwara, 2005; Fujita et al ., 2009).

Thiotrichinae are a subfamily of Gelechiidae with approximately 180 described species in five genera: Calliprora Meyrick, Macrenches Meyrick, Palumbina Rondani, Polyhymno Chambers and Thiotricha Meyrick. The subfamily was established based on two species in a recent molecular phylogenetic study of Gelechiidae, but the monophyly of each genus and the phylogenetic relationships among the genera have not been tested. To address these questions, we performed the first phylogenetic analyses based on seven molecular markers (COI, EF‐1α, GAPDH, RpS5, CAD, Wg and MDH) and 95 morphological characters for 47 ingroup and 3 outgroup taxa. Each dataset was analysed separately and together using maximum likelihood, Bayesian inference and maximum parsimony methods. The maximum likelihood and Bayesian analyses produced nearly identical tree topologies for ingroup relationships, but the parsimony analysis yielded different results for some lineages. In all our analyses, Thiotrichinae formed a strongly supported monophyletic group with two other gelechiid genera, Cnaphostola Meyrick (Gelechiinae) and Semnostoma Meyrick (Apatetrinae). The genus Macrenches was recognized as the sister‐group to all other species in this clade. Polyhymno + Calliprora were found to be sister to all remaining ingroup taxa. The species‐rich group Thiotricha was non‐monophyletic, and it clustered with Palumbina, Cnaphostola and Semnostoma. The type species of Thiotricha was included in a monophyletic clade with a majority of congeneric species in the parsimony analyses, but the clade was divided into two groups in the model‐based results. The generic placement of two species Thiotricha dissobola Meyrick and T. pyrphora Meyrick was not confirmed in this study and they were placed as incertae sedis. The monophyly of Palumbina was strongly supported by both molecular data and morphological evidence. Based on genetic and morphological affinities and examination of the type specimens, four genera are synonymized with Thiotricha: Blastovalva Janse syn.n., Cnaphostola syn.n., Hierangela Meyrick syn.n. and Semnostoma syn.n. We propose two new genera for newly recognized two sub‐clades: Pulchrala gen.n. and Tenupalpa gen.n., and 15 new combinations are made: Thiotricha adamantina (Meyrick) comb.n., T. exalbida (Omelko & Omelko) comb.n., Tenupalpa angustella (Omelko) comb.n., T. biformis (Omelko) comb.n., T. flavitermina (Kyaw, Yagi & Hirowatari) comb.n., T. glenias (Meyrick) comb.n., T. nephodesma (Meyrick) comb.n., T. venustalis (Omelko) comb.n., Pulchrala clidias (Meyrick) comb.n., P. chujaensis (Park) comb.n., P. elaeocarpiella (Kyaw, Yagi & Hirowatari) comb.n., P. epiclista (Meyrick) comb.n., P. melanacma (Bradley) comb.n., P. panglycera (Turner) comb.n., and P. saulotis (Meyrick) comb.n. Revised generic concepts are provided in the study. This published work has been registered on ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:0E3C0EB5-503C-4ADC-BE87-A203230DE6CB.

“…Most Thiotricha species have been reported as foliage or leaf litter feeders. However, Fujita et al (2009) has shown that T. pancratiastis larvae extensively feed on bayberry seeds making them non-viable. However, more studies are needed to identify the micro-moths observed to the species level.…”

Considering the environmental and specific socioeconomic significance of the critically endangered mangrove Lumnitzera littorea, this study was conducted aiming the conservation of the species. The specific objectives were to define the diversity of the other mangrove species in association with the existing L. littorea plant population in the Madu Ganga wetland, Sri Lanka, to study its seed germination and identify the barriers for seed germination. The existing population of L. littorea is an aged population with low regeneration potential. Most of the seeds collected at the dispersal maturity were empty. A micro moth belonging to Family Gelechiidae was identified as the embryo predator. Although GA3 (Gibberellic acid) treatment and dry storage reduced the germination time, none of the seed treatments significantly improved the seed germination of L. littorea. Low seed germination observed was due to absence of embryo in mature seeds as a result of insect predation and physiological dormancy of seeds. Optimum GA3 concentration, duration of dry storage and potting medium with suitable salt concentration for seedlings should be optimized in future research.
