Redescription (
Figure 1 and
Figure 2). Male: length: 7.6–8.4 mm, width: 3.8–4.1 mm. General color yellow, scutellum, basal part of inner margin of epipleuron, apex of suture, lateral of mesosternum, metasternum, and base of first metatarsomere black, ventral surface of head with a black spot, prosternum with three black spots, abdominal ventrites 1–5 with black spots on each side, pygidium with a black spot at apex. Vertex with sparse punctures, median process pointed on apex, lower edge of frons with two round cavities. Antennae slender, equal to length of body. First antennomere shiny bare, rod-shaped, second to eleventh antennomeres with short hairs, second antennomere equal to third (
Figure 2F), fourth antennomere about 5.2× as long as third, fifth to eleventh antennomeres shorter than fourth and gradually shortened. Pronotum about 1.8× as wide as long, lateral margins slightly curved, basal margin slightly convex, apical margin slightly concave, disc with one pair of shallow impressions. Scutellum triangular, smooth, impunctate. Elytra wider than pronotum, humeri convex, disc with dense, minute punctures. Elytral epipleuron broad at base, continues towards apex. Legs thin, densely covered by short recumbent setae. First tarsomeres of front legs strongly swollen and flattened (
Figure 2G). Each tibia with one spur at apex. Aedeagus slender, with parallel sided at base, gradually narrowed at middle, and middle to apex with parallel sided, apex pointed, slightly curved at middle in lateral view (
Figure 2J). Female: length: 7.4–7.6 mm, width: 3.7–4.0 mm. Elytra red or reddish-brown, ventrites 1–3 or 1–5 with black spots on each side, or ventrites 1–3 with black transverse strip. Anterior part of head (
Figure 2E) with a transverse depression and a longitudinal depression. First tarsomeres of front legs slender. Spermatheca (
Figure 2L) with big and rounded nodulus, middle part short, and cornu slightly curved. Vaginal palps (
Figure 2K) with wide base and pointed apex, each palp with three setae placed at apex, additional five setae subapically. Bursa sclerites sharp with 4–6 teeth at inner side (
Figure 2M).
Differential diagnosis. Males of
Macrima armata Baly, 1878 are distinguished by the distinct black frontal process (
Figure 2D). This character is unique within the genus; no other species possesses a black frontal process. Females of this species can be distinguished by a cruciform depression on the frons (
Figure 2E).
Comments. Baly (1878) did not state the exact number of specimens available for the description, but he explicitly described both males and females from Jhelum Valley (Azad Kashmir, Pakistan). Baly’s collection, now deposited in NHMUK, contains three specimens identified as Macrima armata. Only one of these specimens (female) bears the locality label Jhelum Valley and was subsequently provided with the characteristic round type label. Maulik (1936) mentioned only the female as the type specimen, and it was probably he who attached the type label. However, in our opinion, this specimen is a female of Macrima pallida. Additional two specimens are a male of M. armata from Kullu (Himachal Pradesh, India) and a female from Mussoorie (Utarakhand, India), which again pertains to M. pallida. The locality data of these two specimens do not correspond to the original description and therefore cannot be considered type specimens of M. armata. Baly included a male in his original description; however, it is unclear whether this male has not survived or whether Baly made a mistake in his description and simply forgot to include the Kullu locality in the description. Baly explicitly stated that the frontal process in the male is black, which corresponds exactly to the current concept of the species, since M. armata is the only species in which the frontal process is black.

Redescription (
Figure 3,
Figure 4,
Figure 5 and
Figure 6). Male: length: 7.2–8.0 mm, width: 3.7–3.8 mm. General color yellow or yellowish-brown, scutellum, basal part of inner margin of epipleuron, apex of suture, lateral of mesosternum, metasternum and base of first metatarsomere black, ventral surface of head with a black spot, prosternum with three black spots, abdominal ventrites 1–5 with black transverse strip, pygidium with a black spot at apex. In some specimens, elytra red or reddish-brown, lateral margins of elytra black, ventrites 1–5 with black spots on each side, or ventrites 1–3 with black transverse strip, ventrites 4–5 with black spots on each side. Vertex with sparse punctures, upper edge of frons adorned between the antennae with two small processes, median process rounded on apex and pubescent below, lower edge of frons with two triangular processes and two round cavities, lateral edges of frons each with one triangular process. Antennae slender, equal to length of body. First antennomere shiny bare, rod-shaped, second to eleventh antennomeres with short hairs, second antennomere shortest, third antennomere 1.25× as long as second (
Figure 6F), fourth antennomere about 2.6× as long as third, fifth to eleventh antennomeres shorter than fourth and gradually shortened. Pronotum about 1.65× as wide as long, lateral margins slightly curved, basal margin slightly convex, apical margin slightly concave, disc with one pair of shallow impressions. Scutellum triangular, smooth, impunctate. Elytra wider than pronotum, humeri convex, disc with dense, minute punctures. Elytral epipleuron broad at base, continues towards apex. Legs thin, densely covered by short recumbent setae. Fore tibia without spur at apex, first tarsomeres of front legs strongly swollen and flattened (
Figure 6G), 2.6× as long as wide. Aedeagus slender, with parallel sided at base, gradually narrowed towards subapex, subapex to apex with parallel sided, apex pointed, slightly curved at middle in lateral view (
Figure 6J). Female: length: 8.6–8.8 mm, width: 4.0–4.5 mm. Elytra red or reddish-brown, ventrites 1–3 or 1–5 with black spots on each side, or ventrites 1–3 with black transverse strip. Upper edge of frons adorned between the antennae with two small processes, median process small and rounded on apex, lower edge of frons with two small processes, and a longitudinal ridge in middle (
Figure 6E). Fore tibia without spur at apex, first tarsomeres of front legs slender. Spermatheca (
Figure 6L) with big and rounded nodulus, middle part short, and cornu slightly curved. Vaginal palps (
Figure 6K) with wide base and pointed apex, each palp with three setae placed at apex, additional five setae subapically. Bursa sclerites sharp with 5–6 teeth at outside (
Figure 6M).
Differential diagnosis. This species closely resembles
Macrima hartmanni Medvedev, 2009 in anterior part of head. But it differs in having two large triangular processes on upper part of frons (
Figure 6D), whereas
M. hartmanni has only two small, blunt processes. Females of this species can be distinguished by three small rounded protuberances positioned above the middle of frons, whereas
M. hartmanni has a single elongated median process.
Comments. We examined type specimens of
M. aurantiaca deposited in ZMH (1 male, 1 female) (
Figure 3) and RBNS (1 female) along with the type specimens of
M. ferrugina from SEM (2 males) (
Figure 4) and IZCAS (1 female), as well as the holotype of
M. roseofulva (1 male) (
Figure 5) deposited in ZIN. Both
M. roseofulva and
M. aurantiaca exhibit identical frontal modifications. Although the lower edge of the frons in
M. ferrugina has two rounded cavities (
Figure 4B), its aedeagus is morphologically indistinguishable from that of
M. aurantiaca. Based on these morphological congruencies, we propose
M. roseofulva and
M. ferrugina as new synonyms of
M. aurantiaca.

Pronotum about 1.8× as wide as long, lateral margins slightly curved, basal margin slightly convex, apical margin slightly concave, disc with one pair of shallow impressions. Scutellum triangular, smooth, impunctate. Elytra wider than pronotum, humeri convex, disc with dense, minute punctures. Elytral epipleuron broad at base, continues towards apex. Legs thin, densely covered by short recumbent setae. Fore tibia without spur at apex, first tarsomeres of front legs strongly swollen and flattened (
Figure 9G), 1.65× as long as wide. Aedeagus slender, gradually widened from base to submiddle, and gradually narrowed towards apex, strongly curved at middle and slightly curved at subapex in lateral view (
Figure 9J). Female: length 6.4–8.2 mm, width 3.4–4.2 mm. Prosternum with three black spots or totally black, mesosternum and metasternum black, abdominal ventrites 1–5 with black transverse strip. Vertex with sparse punctures, upper edge of frons adorned between the antennae with two small conical processes, median process rounded and small (
Figure 9E). Fore tibia without spur at apex, first tarsomeres of front legs slender. Spermatheca (
Figure 9L) with big and rounded nodulus, middle part short, and cornu strongly curved. Vaginal palps (
Figure 9K) with wide base and pointed apex, each palp with six setae placed at apex, additional one seta subapically. Bursa sclerites sharp with seven teeth at inner side (
Figure 9M).
Differential diagnosis. Males of this species can be distinguished by black elytral margins, and lower frons margin with four deep oval cavities. Female with black elytral margins, and upper edge of frons adorned between the antennae with two small conical processes.
Comments. We examined type specimens of
M.
cornuta deposited in RBNS (1 male) (
Figure 7), ZMH (1 female), and MNHN (1 female), along with the holotype of
M.
bifida deposited in IZCAS (1 male) (
Figure 8). Both species exhibit identical modifications on frons (
Figure 7B and
Figure 8B), and the dissected aedeagus of the holotype of
M. bifida was found to be morphologically indistinguishable from that of the widely distributed
M. cornuta. Consequently,
M.
bifida is proposed as a new synonym of
M.
cornuta.

Redescription (
Figure 12,
Figure 13 and
Figure 14). Males: length: 6.4–7.5 mm, width: 3.3–3.7 mm. General color yellowish brown, scutellum, basal part of inner margin of epipleuron, apex of suture, apex of lateral margins black, spot on ventral side of head, large spot on prothoracic hypomeron, blurred small spots on prosternum in front of coxal cavities, mesosternum, metasternum, basal parts of abdominal ventrites 1–3, transverse lateral spots on abdominal ventrites 4–5, large apical spot on pygidium, metacoxae and base of first metatarsomere black. The black spots on prothoracic hypomeron and prosternum often missing. Apical antennomeres infuscate. Vertex densely covered with fine punctures and microsculpture, and anterior part of head with large transverse subtrapezoidal cavity, its anterior margin undulated, in middle with small subtriangular process split at setose apex; anterolateral margins of cavity with small subtriangular lamela; cavity in middle with large finger-like process covered with dense short setae; posterior margin with two large triangular processes just under antennal insertions. In some specimens, lower edge of frons with two slightly depressions or two circular cavities. Antennae filiform, as long as of body, first antennomere lustrous, moderately clavate, second to eleventh antennomeres with short hairs, second and third short (
Figure 14F), equal in length, fourth antennomere distinctly flattened, about 4.8× as long as third, fifth to eleventh antennomeres shorter than fourth and gradually shortened. Pronotum transverse, about 1.85× as wide as long. Surface glabrous, semiopaque, covered with fine punctures and microsculpture. Lateral margins moderately rounded, basal margin slightly convex, apical margin slightly concave, disc with one pair of shallow impressions. Scutellum triangular with rounded tip, smooth, impunctate. Elytra wider than pronotum, strongly convex, surface densely covered with fine confused punctures, nearly glabrous, very sparsely covered with almost indistinct short setae. Elytral epipleuron broad at base, continues towards apex. Elytral apex truncate, margin with several short setae. Legs thin, densely covered by short recumbent setae. All tibiae with apical spur, spur on pro- and meso tibiae short, spur on metatibiae longer. In some specimens, protibiae without spur. First tarsomeres of front legs strongly swollen and flattened (
Figure 14G), 2.6× as long as wide. Aedeagus with triangular tip, apical fifth slender and parallel, middle part divergent towards base, basal third wide and subparallel. In lateral view aedeagus moderately bent in middle part and slightly bent subapically (
Figure 14J). Females: length 5.8–8.7 mm, width 2.9–4.3 mm. Third antennomere about twice as long as second. Protarsomere slender, not enlarged. Head with less developed modifications (
Figure 14E): surface uneven, transverse cavity reduced to large subtriangular impressions, median process reduced but visible. Triangular processes on posterior margion of cavity much smaller. Spermatheca (
Figure 14L) with big and rounded nodulus, middle part short, and cornu strongly curved. Vaginal palps (
Figure 14K) with wide base, each palp with five setae placed at apex, additional three setae subapically. Bursa sclerites sharp with six teeth at inner side (
Figure 14M).
Differential diagnosis. Males of this species can be identified by a large transverse subtrapezoidal cavity on frons (
Figure 14D), and second and third antennomeres equal in length (
Figure 14F). Female with one circular shallow depression on each side of frons (
Figure 14E).
Comments. We examined a substantial number of M. pallida and M. yunnanensis specimens, including their type specimens deposited in ZMH and MNHN. Both species were originally described by Laboissière (1936). While the original descriptions and type specimens suggested differences in the lower margin of the frons between the two species, extensive specimen examination revealed intraspecific variation in this character: the margin may exhibit either indistinct shallow depressions or small rounded cavities in males. Dissection confirmed no significant differences in male genitalia (aedeagus morphology), and both taxa share overlapping distribution ranges. Given these morphological and biogeographical congruencies, we synonymize M. yunnanensis under M. pallida, designating the former as a new junior synonym. Due to the relatively wide distribution of this species, the use of M. yunnanensis may lead to misunderstandings regarding its distribution. We recommend adopting the name M. pallida.
