Indeed, some authors have confused Habropoda with other genera of the tribe Melectini, for example Tetralonioidella meghalayensis Dohling &amp; Dey, 2024 was synonymised with Habropoda radoszkowskii (Dalla Torre, 1896) by Orr et al. (2024) in the same year it was first published. The genus Habropoda can be characterised by the absence of a flabellum on the glossa, the mandible bidentate in both sexes, the length of flagellomere I of females 2.75× or more its apical width and 0.75× or more the length of the scape, malar space linear to slightly less than flagellomere width, forewing pterostigma typically longer than wide, 1m-cu terminating at or near apex of second submarginal cell, anterior border of third submarginal cell much shorter than posterior border owing to curvature of 2rs-m, hind wing cu-a conspicuously oblique, gonostylus of male divided into dorsal and ventral processes, and sternum VII of males strongly sclerotised with the disc giving rise to a large apical process, the base of which often bears a transverse ridge. In Palearctic species the procoxae of males often have a long apical spur. Keys to the genera of Anthophorini distinguishing Habropoda are provided by Michener (2007) and Engel (2018).

Initially, while collecting bees we accidentally used slightly too much ethyl acetate and this resulted in the setae becoming matted particularly on the metasoma. Thus, the setae were stuck together and became discoloured when dried. This left the setae of terga II–IV in females appearing black (as Lieftinck (1974) mentioned in his key, p. 175). On a subsequent excursion, by reducing the amount of ethyl acetate, setae on the body were kept drier and the true colours of this subspecies were preserved and illustrated (see Figs. 1–3). We observed the morphology of the females collected from northern provinces, and found that they perfectly matched the description of H. disconota by Lieftinck (1974). Moreover, upon dissecting sterna VII–VIII and the genitalia of associated males from the same location, these structures appeared remarkably similar to Lieftinck’s (1974: fig. 5, 6) illustrations of male genitalia of H. mimetica (see also Wu, 2000: fig. 172). The differences are minor and we believe it is best to consider H. disconota as a geographical subspecies of H. mimetica .</p><p>Distribution. Vietnam (Northern).</p><p>Floral association. Females and males were collected on flowers of Rubus alceifolius Poir. and Rubus sp. ( Rosaceae: Rosoideae) (Fig. 20A, B). These plants often grow in bushes at forest edges in relatively humid locations. The bees often visit flowers that are quite high up or other hard-to-reach locations and, likewise, easier to escape from in case of attack. Like most Anthophorini bees, they are exceptionally quick, making capture on the wing challenging.</p></div>	https://treatment.plazi.org/id/F303879EFFBFFFCBFF50FA19FA9BF7CE	Public Domain	No known copyright restrictions apply.

In both sexes, clypeus strongly convex medially; labrum subrectangular with small, shallow emargination; tergum I completely with long, dense, plumose setae; terga I–V with setal bands of dense plumose setae on apical border apically, those of females broader, thicker than those of males. In female, clypeus with T-inverted yellowish mark medially; pygidial plate with lateral margins gradually narrowed to basal ⅔, then slender on the remaining part and apex nearly rounded. In males, sternum VII strongly constricted at about midlength; discal (distal) portion diamond-shaped and covered with fine, short setae; sternum VIII concave apically and with some short setae. Male gonostylus with the dorsal process long, expanded gradually from base to apex, round apically with long setal tuft, and the ventral process obovate-shape, with dense setae.</p><p>Distribution. China, Taiwan, and Vietnam.</p><p>Included species. Habropoda sinensis Alfken, 1937 and H. taiwana Dubitzky, 2007, new status (elevated to species rank owing to the significant differences in the hidden male sterna and morphological traits outlined in the key below).</p><p>Remarks. This is a complex of exceedingly similar species and which were previously considered subspecies of a single species (Dubitzky, 2007). The discovery of a new form of this group from Vietnam clearly intermingled some of the more minor external morphological features but has a wholly unique form of the male terminalia, and is described as a new species. This led us to reinterpret the subspecies of H. sinensis, in which the male terminalia among the mainland and Taiwanese forms also differ significantly. We therefore believe this is a complex of three closely related species. Based on differences in illustrations from existing publications (Lieftinck, 1974; Dubitzky, 2007), the Vietnamese population superficially resembles H. sinensis from mainland China in most characters but has the male antennal form of H. taiwana from Taiwan. Distinctions between the forms are outlined by Dubitzky (2007: 55–56) and it is clear that each population has unique forms to the male sterna VII and VIII. We consider the Vietnamese population a new species, raise the other two forms to species rank within the sinensis complex, and present here a key to the three species.</p></div>	https://treatment.plazi.org/id/F303879EFFBBFFC9FECCF97CFE83FC2E	Public Domain	No known copyright restrictions apply.

In males, apical portion of sternum VII situated beyond the two heavily sclerotised transverse lateral ridges, at first parallel-sided, then much expanded and terminating in a pair of divergent flaps separated by a broad shallow median emargination; sternum VII with broad medio-apical emargination, discal portion with dense setae; sternum VIII with slight medio-apical emargination. Male gonostylus with dorsal process spatular, long — nearly twice as long as ventral process — with long setae; ventral process longer than broad, with short setae.</p><p>Remarks. This is the first record of H. tainanicola for Vietnam. The species has been separated into two subspecies: H. tainanicola tainanicola Strand, 1913 from Taiwan and H. t. maiella Lieftinck, 1974 from southeastern China. The Vietnamese material is easily distinguished from both of these. Accordingly, we here recognise a third subspecies, with the most obvious character-state differences outlined in table 1.</p></div>	https://treatment.plazi.org/id/F303879EFFB3FFC1FF09F896FC35F7D7	Public Domain	No known copyright restrictions apply.

Vietnam (Northern and Central Highlands).</p><p>Remarks. H. tumidifrons has been recorded in the Central Highlands, Vietnam (Lam Dong province). This species is most similar in the Vietnamese fauna to H. pierwolae owing to the form of the body and shape of the male gonostylus, but can be separated from the latter based on the following: 1) in both sexes, clypeus gently convex in profile (clypeus profile strongly convex in H. pierwolae), 2) in females, apical margins of terga I–III with thin linear, ochraceous-orange setal bands and of tergum IV with black setal band (apical margins of terga I–IV with thick, uniform, bright yellow setal bands in H. pierwolae), 3) sternum VII of males narrowed near midlength, apical disc hexagon-shaped (sternum VII of males not expanded medially nor hatchet-shaped, tapering slightly from midlength to apical margin with broad medioapical lobe in H. pierwolae); 4) sternum VIII of males expanded horizontally, round apically (sternum VIII of males with lateral margins of disc almost straight, converging to apical margin with broad medial concavity between to apical angles, concavity with minute, bluntly rounded lobe in H. pierwolae), and 5) the dorsal process of male gonostylus slightly expanded apically (the dorsal process of male gonostylus much expanded apically in H. pierwolae). This species was described by Lieftinck (1974) based on a unique female collected in the Central Highlands of Vietnam (Lam Dong Province). The present paper describes the male of H. tumidifrons for the first time.</p><p>Floral association. This species was collected at flowers of Rubus multibracteatus Levl. and Rubus pyrifolius Sm. ( Rosaceae: Rosoideae) (Fig. 20E, F).</p><p>Nesting biology. In Cham Chu Natural Reserve (Tuyen Quang Province), six nests were found within an area of about 3 m 2 and were constructed into the soil (in some areas with a layer of moss) floor of a stilt house (Fig. 19D). The nests were only observed during the earliest stages of the nest building process, with nest entrance diameter and nest length of about 1.5 cm and 15 cm, respectively (Fig. 19C). During the nesting process, the bees’ excavation produced small humus particles around the nest entrance (Fig. 19A). In Quang Thanh Commune (Cao Bang Province), four nests were found on the ground of an abandoned house, and were also only early in development.</p></div>	https://treatment.plazi.org/id/F303879EFFAFFFD9FF1AF894FE64F9F1	Public Domain	No known copyright restrictions apply.
