Zootaxa 5666 (2): 195-210, DOI: 10.11646/zootaxa.5666.2.3, URL: https://doi.org/10.11646/zootaxa.5666.2.3
C13987B8FFE65E3205B26D751D907C2B.taxon	discussion	Notes. Comparison of females of the 10 species of Loeia for which females are available indicates that the ovipositor structure of this genus is highly conserved, with no obvious differences between species other than relative length proportional to differences in overall body length. The shape of the pregenital sternite is distinctive for some species but highly similar among others (cf. Figs 7 E – N). This genus was originally placed in Deltocephalini a widespread grass-specialist tribe recognized by the linear connective fused to the aedeagus. Loeia differs from most genera of Deltocephalini in its much larger body size, short crown with anterior and posterior margins usually subparallel, anteclypeus with lateral margins divergent distally, and lora well separated from the ventral margin of the face. Species of Deltocephalini are usually small with the crown distinctly produced anteriorly, the anteclypeus tapered distally, and the lora extended to or very near the ventral margin of the face. Thus, the linear connective fused to the aedeagus is one of few diagnostic characters of Deltocephalini shared by Loeia and this trait also occurs in some other deltocephaline tribes (see Introduction). The structure of the head of Loeia is more similar to that of Punctulini, particularly the genera included in the tribe by Dietrich et al. (2020) and Ramaiah et al. (2023). The dorsal color pattern, consisting of numerous small brown spots merging to form larger areas, is also shared with Pseudocestius Dietrich, Nguyen & Pham, 2020 and the presence of supernumerary crossveins in the forewing is shared with Hochiminhus Dietrich, Nguyen & Pham, 2020. The linear connective is similar to that of Bambuphaga Ramiah, Meshram & Dey, 2023 but species of the latter genus are much smaller and the male pygofer is not elongate. The ovipositor of Loeia, with a submarginal band of sculpture on the first valvula and teeth reduced or absent on the second valvula, resembles that of Hecalusina He, Zhang & Webb, 2008, a genus previously placed in Hecalini that also grouped with Punctulini in the analyses of Cao et al. (2022). These morphological traits, along with the available molecular evidence, support transferring Loeia to Punctulini. Loeia lacks one of the main diagnostic morphological traits shared by genera previously placed in Punctulini; the elongated, divergent and capitate male second abdominal apodemes. Species of Loeia have these apodemes well developed, but they are relatively short, flaplike, and oriented obliquely such that they appear tapered in ventral aspect (Figs 7 O-P). Maximum likelihood-based phylogenomic analyses of concatenated nucleotide or amino acid sequences (Cao et al. 2022) consistently placed Loeia as sister to the remaining Punctulini, within a larger clade of leafhoppers belonging to the bamboo-specialist deltocephaline tribes Mukariini and Vartini as well as bamboo-associated genera currently placed in the polyphyletic tribe Athysanini. This placement seems consistent with the absence of capitate 2 S abdominal apodemes in Loeia, which may have retained a more plesiomorphic condition of this trait than is present in other members of Punctulini. Ecological data for Punctulini are sparse, but their close relationship to other deltocephaline leafhoppers that specialize on bamboos (Poaceae: Bambusoidea), strongly suggests that Loeia and other Punctulini are also bamboo specialists. The presently known species of Loeia appear to be nearly identical in external appearance including structure and coloration, except for overall body size and head proportions, which overlap somewhat among species. Slight differences in color pattern, wing venation, and leg chaetotaxy evident in the habitus photos (Fig. 1) often vary among specimens within species. Thus, species of the genus are most reliably distinguished by the male genitalia (Figs 2 – 6) and, in some cases, by the shape of posterior margin of the female pregenital sternite (Fig. 7).	en	Dietrich, Christopher H.

Head in dorsal view with crown no longer medially than next to eye, 1.8 × wider at base than medial length, anterior and posterior margins parallel. Male pygofer ~ 3.5 × longer than maximum height, ventral spine well developed, extended dorsomesad and slightly posterad. Subgenital plate not extended to midlength of pygofer, laterally convex basal section as long as concave distal section.

C13987B8FFEA5E3905B26AC819827BDE.taxon	discussion	Notes. This species was originally described and illustrated by based on a single male specimen from Loei province (Duan et al. 2017). Additional males and a single female discovered more recently expand the known range of this species to include Chiang Mai and Suphanburi provinces. The seventh sternite of a female from the type locality is illustrated in Fig. 7 M.	en	Dietrich, Christopher H.

Head in dorsal view with crown slightly longer medially than next to eye, 1.7 × wider at base than medial length, anterior and posterior margins parallel. Male pygofer ~ 3.5 × longer than maximum height, without ventral processes. Subgenital plate not reaching midlength of pygofer. Style relatively short, robust, preapical lobe broadly rounded, apex footlike with angulate heel opposite short toe.
