(2025): Life on sticky plants: two new species of Mitrapsylla (Hemiptera: Psylloidea: Psyllidae) on Chamaecrista (Fabaceae) in the Brazilian Highlands. Zootaxa 5727 (1): 70-100, DOI: 10.11646/zootaxa.5727.1.6, URL: https://doi.org/10.11646/zootaxa.5727.1.6
446412329E04FFF0DCAFFBD97C0D1C1E.taxon	discussion	Comments. Mitrapsylla burckhardtiella sp. nov. shows a variation in the body colouration of the adults (Figs 1 A – H, 2 A – D), which is probably due to differences in the age of the specimens. Such intraspecific variation is also common in other species of Mitrapsylla (Rendón-Mera et al. 2020). The adults studied here also show a relatively large variation in overall body size and the relative length of the hind tibia, as well as some variation in the distribution of surface spinules on the forewing membrane (Fig. 3 C, D). Since other characters, particularly the structure of the male and female terminalia, are constant in the different specimens and no consistent patterns could be identified, this variation is also considered to be intraspecific and perhaps partly due to the quality of the host plant (cf. Sutton 1984). The p - distance between specimens of M. burckhardtiella from different localities is 5.7 – 7.0 % for COI and 4.8 – 8.6 % for cytb. This is also quite high for intraspecific variation in animal species, but not unusual for Neotropical psyllids (cf. Serbina et al. 2025 b). For comparison, the genetic distance between M. burckhardtiella and M. danieli is 14.6 – 16.3 % for COI and 21.5 – 23.2 % for cytb, while between M. fusca and M. machaerii it is 12.2 % for COI and 21.2 % for cytb. The adults of M. burckhardtiella sp. nov. can be distinguished from other Mitrapsylla species by their very long legs (ratio metatibia length / head width = 1.0 – 1.5) and the rostrum; all other Mitrapsylla species described so far have relatively shorter legs, with the metatibia being 0.5 – 0.9 times as long as the head width (Rendón-Mera et al. 2020; see also Brown & Hodkinson 1988). Among the immatures of Mitrapsylla known to date (cf. Burckhardt & Brown 1992; Burckhardt & Queiroz 2020), the immatures of M. burckhardtiella sp. nov. are unique not only for their long and slender legs and rostrum, but also for the long and thick capitate setae, which cover the entire dorsum of the body and arise from sclerotised tubercles on the abdomen, as well as for the ventrally located anus, the presence of only 2 + 2 truncate sectasetae on the caudal plate (instead of 4 + 4 in other Mitrapsylla spp.), the presence of rows of thick setae on apical tarsal segment ventrally and the small arolium in relation to the large claws. Using the identification key for Brazilian Mitrapsylla by Rendón-Mera et al. (2020), the character states of the adult males of M. burckhardtiella sp. nov. lead to the couplet no. 37, which includes M. amazonica Rendón-Mera et al., M. xanthoptera Rendón-Mera et al. and M. cassiae Rendón-Mera et al. Mitrapsylla burckhardtiella sp. nov. is similar to M. amazonica in the short, subacute genal processes, but differs in the dense surface spinules that completely cover the cells in the apical part of the forewing (reduced around the radular areas of cells m 1, m 2 and cu 1 in M. amazonica) and the narrowly rounded paramere apex (truncated in M. amazonica). In the latter two characters, M. burckhardtiella sp. nov. resembles M. xanthoptera and M. cassiae, but both are characterised by larger genal processes and a larger apical part of the ventral process of the aedeagus in relation to its dorsal lobe, compared to M. burckhardtiella. Mitrapsylla cassiae also differs from M. burckhardtiella by the basally expanded paramere, the tripartite dorsal lobe of the aedeagus and the host plant, which is Cassia leptophylla (host plants are unknown for M. amazonica and M. xanthoptera). The female terminalia of M. burckhardtiella sp. nov. also differ from M. amazonica, M. cassiae and M. xanthoptera in the shape, chaetotaxy and relative length of the proctiger and subgenital plate (cf. Rendón-Mera et al. 2020). Mitrapsylla burckhardtiella sp. nov. differs from M. danieli sp. nov., the only other Mitrapsylla species known so far from Chamaecrista, not only by the long legs and immature characters but also by the short genal processes (0.6 times as long as the vertex along the midline in M. danieli), relatively longer antennae (1.9 – 2.0 times as long as the head width in M. danieli) and forewings (2.9 – 3.0 as long as the head width in M. danieli), relatively shorter antennal terminal setae (more than half as long as antennal segment 10 in M. danieli), forewings with infuscation on the membrane concentrated along the veins (not in the middle of the cells in the apical third of the wing, as in M. danieli) and denser surface spinules, often extending to the veins (less dense and with distinct spinule-free bands along the veins in M. danieli), the relatively slender and straight paramere with sclerotised apical ridge situated dorsally in the longitudinal axis of the paramere (broader and with sclerotised apical ridge displaced posteriorly in M. danieli), the unipartite and narrower dorsal lobe of the distal segment of the aedeagus (tripartite and broader in M. danieli), and the female proctiger mostly straight dorsally (clearly concave in M. danieli). Mitrapsylla burckhardtiella sp. nov. should not be confused with M. burckhardti Brown & Hodkinson from Panama. Although the name is similar, M. burckhardti differs from M. burckhardtiella sp. nov. by the longer and apically broadly rounded genal processes, the shorter rostrum and hind legs, the reduced surface spinules that leave broad spinule-free bands around veins or are absent, the paramere, which is narrowly lanceolate in lateral view, not expanded posteriorly in the apical third, the ventral process and dorsal lobe of the aedeagus, which are fused together and not clearly separated, and the apex of the female proctiger, which is curved upwards. The host plant of M. burckhardti is unknown (Brown & Hodkinson 1988).	en	Malenovský, Igor, Serbina, Liliya Š., Queiroz, Dalva L.

446412329E0FFFE8DCAFFF357FC8190E.taxon	discussion	Comments. Using the identification key for Brazilian Mitrapsylla by Rendón-Mera et al. (2020), the character states of the adult males of M. danieli sp. nov. lead to the couplet no. 22. Mitrapsylla danieli sp. nov. resembles M. clavata Rendón-Mera et al. in the multicoloured head and thorax and the tripartite dorsal lobe of the aedeagus, but differs in the shape of the genal processes, which in M. danieli are expanded and have a broadly rounded apex (subconical with subacute apex in M. clavata), the paramere, which is relatively shorter and broader and is strongly expanded in the apical third in M. danieli (relatively slender, only weakly apically expanded in M. clavata), and the relatively longer subgenital plate (only 0.4 – 0.5 times as long as the proctiger in M. clavata). The general structure of the genal processes, paramere and aedeagus of M. danieli sp. nov. is also similar to M. fusca Brown & Hodkinson from Panama and M. machaerii Rendón-Mera et al. from Brazil. Mitrapsylla danieli differs from M. fusca in having larger genal processes (0.4 – 0.5 times as long as vertex in M. fusca according to Brown & Hodkinson 1988), more extensive surface spinules on the forewing membrane (in M. fusca only in the cells cu 2, m 2 and r 1) and the paramere with convex posterior margin and narrowly rounded apex (with sinuous posterior margin and broadly rounded apex in M. fusca). Mitrapsylla danieli sp. nov. differs from M. machaerii by the less pronounced apicoposterior lobe of the paramere and sclerotised apical ridges as well as by the absence of a group of thick setae in this region (present in M. machaerii) and by the relatively longer subgenital plate (0.5 – 0.6 times as long as the proctiger in M. machaerii). It also differs from M. fusca and M. machaerii by the host plant (Machaerium spp. in the latter two species). The fifth instar immature of M. danieli sp. nov. resembles M. gloriae Burckhardt & Queiroz and M. surinamensis (Šulc) in the small, weakly indented outer circumanal ring, which barely extends to the dorsal side of the caudal plate. It differs from these species by longer and more numerous capitate setae on the dorsum and by the host plant; in M. gloriae the host plants are Copaifera spp. and in M. surinamensis Andira inermis and Machaerium spp. (Burckhardt & Brown 1992; Burckhardt & Queiroz 2020). For the differences between M. danieli sp. nov. and M. burckhardtiella sp. nov. see the comments under the latter.	en	Malenovský, Igor, Serbina, Liliya Š., Queiroz, Dalva L.
