BODY LENGTH. Males = 1.7 to 2 mm; females = 2.4 to 3 mm.

COLORATION. Body mainly black, with coppery sheen ( Fig. 6 View Fig A–F). Forewings ( Fig. 6B, E View Fig ) black. Males with legs mostly yellow, except femur III black basally ( Fig. 6A, C View Fig ). Females with legs light brown with black maculae ( Fig. 6D, F View Fig ).

HEAD AND THORAX. Vertex ( Fig. 6B, E View Fig ) semicircular, shorter than half its width, shorter than half of pronotum length; posterior margin slightly elevated. Frons ( Fig. 6A, D View Fig ) with median carina and pair of sublateral carinae; sublateral carinae converge and fuse to each other ventrally; central plate ( Fig. 6A, D View Fig ) as long as wide at widest portion, visible in dorsal view ( Fig. 6B, E View Fig ), extending slightly anteriorly beyond sublateral carinae in lateral view ( Fig. 6C, F View Fig ); sides of frons partially visible in frontal view ( Fig. 6A, D View Fig ) and fused above clypeus, with two rows of sensory pits on each side in lateral view ( Fig. 6C, F View Fig ): anterior row with eight sensory pits; posterior row with four sensory pits. Clypeus ( Fig. 6C, F View Fig ) 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 View Fig ) 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 View Fig ) with three sensory pits arranged in row. Mesonotum ( Fig. 6B, E View Fig ) 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 View Fig , 26C View Fig ) without sensory pits. Tergite IV ( Figs 6C, F View Fig , 26C View Fig ) 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 View Fig , 26C View Fig ) with one row of three to five sensory pits followed by isolated ventral pair aligned diagonally. Tergite VIII ( Fig. 26C View Fig ) with one sensory pit.

MALE TERMINALIA. Pygofer ( Fig. 7A View Fig ) narrow, with anterior margin concave; posterior margin almost straight. Connective ( Fig. 7B View Fig ) inverted Y-shaped, with support bridge with dorsal flap. Style ( Fig. 7 View Fig C–D) hook-like; anterior portion pointed; caudal portion strongly curved anterodorsally ( Fig. 7D View Fig ) and curved mesad in dorsal view ( Fig. 7C View Fig ); dorsal margin ( Fig. 7D View Fig ) sinuous; ventral margin ( Fig. 7D View Fig ) with straight angle concavity on anterior fourth, remainder rounded; middle third ( Fig. 7D View Fig ) as long as high, setose; apex serrated ( Fig. 7D View Fig ). Phallobase ( Fig. 7 View Fig E–H) sclerotized, symmetrical, with two defined lobes; apex with pair of lobes with apices truncate in dorsal view ( Fig. 7 View Fig E–F) and rounded in lateral view ( Fig. 7 View Fig G– H); sides expanded and rounded at half-length of aedeagus in dorsal view ( Fig. 7 View Fig E–F); with dorsal process near apex in lateral view ( Fig. 7 View Fig G–H), surrounding apical half of aedeagus; with a flap covering aedeagal hook in lateral view ( Fig. 7 View Fig G–H). Aedeagus ( Fig. 7 View Fig E–F) apex narrow and open dorsally; with pair of hooks, one curved dorsally ( Fig. 7 View Fig E-F), other curved anteroventrally ( Fig. 7 View Fig G-H). Suspensorium V-shaped. Segment X of anal tube ( Fig. 7 View Fig I–J) as long as wide, posterior margin ( Fig. 7I View Fig ) pointed; setose.

FEMALE TERMINALIA. Posterior margin of sternite VII ( Fig. 8B View Fig ) with median portion produced, setose. Gonoplac ( Fig. 8C View Fig ) sclerotized, sub-rectangular with apex truncate, setose.Anterior connective lamina of gonapophysis VIII ( Fig. 8D View Fig ) 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 View Fig E–F) distal part with longitudinal row of eight short and wide spines in lateral view ( Fig. 8F View Fig ); middle portion with several pits ( Fig. 8F View Fig ); apex setose ( Fig. 8F View Fig ); region between distal parts with two patches of small setae ( Fig. 8E View Fig ). Segment X of anal tube ( Fig. 8 View Fig G–H) longer than wide at widest portion, posterior margin ( Fig. 8G View Fig ) 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 View Fig ) and shorter snout ( Fig. 6C, F View Fig ), which distinguish it from B. oculata ; (2) small size, which distinguishes it from B. tristis ; (3) shorter snout and yellow legs ( Fig. 6C, F View Fig ), which distinguish it from B. minima ; and (4) circular central plate of frons ( Fig. 6A, D View Fig ), which is much less elongated than in B. pallidipes .
