Diagnosis
Body mainly black, with coppery sheen (Fig. 6); vertex semicircular (Fig. 6B, E); frons with median carina (Fig. 6A, D), central plate visible in dorsal view (Fig. 6B, E); clypeus swollen, but not forming snout (Fig. 6C, F); lateral lobe of pronotum with three sensory pits arranged in a row (Fig. 6C, F);
abdominal tergites (Figs 6C, F, 26C) with row of sensory pits followed by single isolated ventral sensory pit (tergite IV) or isolated pair of diagonally aligned ventral sensory pits (tergites V to VII).

Description
BODY LENGTH. Males = 1.7 to 2 mm; females = 2.4 to 3 mm.
COLORATION. Body mainly black, with coppery sheen (Fig. 6 A–F). Forewings (Fig. 6B, E) black. Males with legs mostly yellow, except femur III black basally (Fig. 6A, C). Females with legs light brown with black maculae (Fig. 6D, F).
HEAD AND THORAX. Vertex (Fig. 6B, E) semicircular, shorter than half its width, shorter than half of pronotum length; posterior margin slightly elevated. Frons (Fig. 6A, D) with median carina and pair of sublateral carinae; sublateral carinae converge and fuse to each other ventrally; central plate (Fig. 6A, D) as long as wide at widest portion, visible in dorsal view (Fig. 6B, E), extending slightly anteriorly beyond sublateral carinae in lateral view (Fig. 6C, F); sides of frons partially visible in frontal view (Fig. 6A, D) and fused above clypeus, with two rows of sensory pits on each side in lateral view (Fig. 6C, F): anterior row with eight sensory pits; posterior row with four sensory pits. Clypeus (Fig. 6C, F) swollen, extending anteriorly but not producing snout in lateral view; with complete median carina. Ocelli absent. Eye oblong. Antenna short, with several small circular structures visible on pedicel. Pronotum (Fig. 6B, E) semicircular, shorter than half its width, with median carina; median portion of disc without sensory pits; lateral portion of disc with 12 to 14 sensory pits on each side; lateral lobe of pronotum (Fig. 6C, F) with three sensory pits arranged in row. Mesonotum (Fig. 6B, E) with median carina and pair of lateral carinae; region between lateral carinae without sensory pits; regions outerad of lateral carinae with 10 to 11 sensory pits on each side. Brachypterous, with reduced venation. Legs simple, with carinae and setae; tibia III with single median spine.
ABDOMEN. Terga without longitudinal carinae. Tergite III (Figs 6C, F, 26C) without sensory pits. Tergite IV (Figs 6C, F, 26C) with one row of three to five sensory pits, with penultimate pit slightly displaced from row, followed by single isolated ventral one. Tergites V to VII (Figs 6C, F, 26C) with one row of three to five sensory pits followed by isolated ventral pair aligned diagonally. Tergite VIII (Fig. 26C) with one sensory pit.
MALE TERMINALIA. Pygofer (Fig. 7A) narrow, with anterior margin concave; posterior margin almost straight. Connective (Fig. 7B) inverted Y-shaped, with support bridge with dorsal flap. Style (Fig. 7 C–D) hook-like; anterior portion pointed; caudal portion strongly curved anterodorsally (Fig. 7D) and curved mesad in dorsal view (Fig. 7C); dorsal margin (Fig. 7D) sinuous; ventral margin (Fig. 7D) with straight angle concavity on anterior fourth, remainder rounded; middle third (Fig. 7D) as long as high, setose; apex serrated (Fig. 7D). Phallobase (Fig. 7 E–H) sclerotized, symmetrical, with two defined lobes; apex with pair of lobes with apices truncate in dorsal view (Fig. 7 E–F) and rounded in lateral view (Fig. 7 G– H); sides expanded and rounded at half-length of aedeagus in dorsal view (Fig. 7 E–F); with dorsal process near apex in lateral view (Fig. 7 G–H), surrounding apical half of aedeagus; with a flap covering aedeagal hook in lateral view (Fig. 7 G–H). Aedeagus (Fig. 7 E–F) apex narrow and open dorsally; with pair of hooks, one curved dorsally (Fig. 7 E-F), other curved anteroventrally (Fig. 7 G-H). Suspensorium V-shaped. Segment X of anal tube (Fig. 7 I–J) as long as wide, posterior margin (Fig. 7I) pointed; setose.
FEMALE TERMINALIA. Posterior margin of sternite VII (Fig. 8B) with median portion produced, setose. Gonoplac (Fig. 8C) sclerotized, sub-rectangular with apex truncate, setose.Anterior connective lamina of gonapophysis VIII (Fig. 8D) with three apical teeth: innermost bigger than outer ones, narrow and long, middle one widest, outer one short and apically rounded. Posterior connective lamina of gonapophysis IX (Fig. 8 E–F) distal part with longitudinal row of eight short and wide spines in lateral view (Fig. 8F); middle portion with several pits (Fig. 8F); apex setose (Fig. 8F); region between distal parts with two patches of small setae (Fig. 8E). Segment X of anal tube (Fig. 8 G–H) longer than wide at widest portion, posterior margin (Fig. 8G) pointed with apex rounded; setose.
Remarks
Specimens at hand were identified based on the redescription and illustration of the dorsal view of the body, lateral view of the head, and male terminalia by Doering (1939). This species resembles several other species of Bruchomorpha, including Bruchomorpha oculata Newman, 1838, Bruchomorpha minima Metcalf, 1923, Bruchomorpha pallidipes Stål, 1862 and Bruchomorpha tristis Stål, 1862, in its mostly black, metallic shiny appearance. According to Doering (1939), B. mormo can be easily distinguished from other black-colored species by: (1) lack of a lighter colored dorsal stripe (Fig. 6B, E) and shorter snout (Fig. 6C, F), which distinguish it from B. oculata; (2) small size, which distinguishes it from B. tristis; (3) shorter snout and yellow legs (Fig. 6C, F), which distinguish it from B. minima; and (4) circular central plate of frons (Fig. 6A, D), which is much less elongated than in B. pallidipes.
