Description

BODY LENGTH. Male (holotype of Bruchomorpha decorata Metcalf, 1923 ) = 2.6 mm; females = 3.4 to 4.0 mm.

COLORATION. Body mainly black with several pale maculae in males ( Fig. 3 View Fig A–C); females ( Fig. 3 View Fig D–F) having lighter, dark brown coloration overall with pale maculae larger than in males. Central plate of frons ( Fig. 3A, D View Fig ) with pale heart-shaped macula divided by median carina; side of frons ( Fig. 3C, F View Fig ) pale. Pronotum ( Fig. 3B, E View Fig ) mostly pale; lateral lobe of pronotum ( Fig. 3C, F View Fig ) with posterior half pale. Mesonotum ( Fig. 3B, E View Fig ) with anterior and posterior portions of middle region distinctly pale. Forewings black in males ( Fig. 3 View Fig B–C) and hyaline in females ( Fig. 3 View Fig E–F), both with white veins.

HEAD AND THORAX. Vertex ( Fig. 3B, E View Fig ) hexagonal, shorter than half its width, shorter than pronotum length; posterior margin slightly elevated. Frons ( Fig. 3A, D View Fig ) with strong median carina and pair of sublateral carinae; sublateral carinae convergent and fused to each other ventrally; central plate ( Fig. 3A, D View Fig ) longer than wide at widest portion, visible in dorsal view ( Fig. 3B, E View Fig ), not extending anteriorly beyond sublateral carinae in lateral view ( Fig. 3C, F View Fig ); sides of frons partially visible in frontal view ( Fig. 3A, D View Fig ) and fused above clypeus, with two rows of sensory pits on each side in lateral view ( Fig. 3C, F View Fig ): anterior row with eight sensory pits, five dorsal ones grouped together, followed by sixth isolated one aligned with antenna, and pair of ventral ones isolated next to clypeus; posterior row with four sensory pits, most ventral one slightly isolated. Clypeus ( Fig. 3C, F View Fig ) swollen, extending anteriorly in lateral view, consequently pushing frons anteriorly and producing very lightly produced snout; longer than high in lateral view, with complete and elevated median carina. Ocelli absent. Eye oblong. Antenna short, with several small circular structures visible on pedicel. Pronotum ( Fig. 3B, E View Fig ) semicircular, shorter than half its width, with distinct median carina; median portion of disc without sensory pits; lateral portion of disc with 15 to 19 (holotype and allotype with 18 to 19) sensory pits; lateral lobe ( Fig. 3C, F View Fig ) with three (holotype) to four sensory pits arranged in row. Mesonotum ( Fig. 3B, E View Fig ) with distinct median carina and pair of lateral carinae; region between lateral carinae depressed, without sensory pits; region outerad of lateral carina with 10 to 13 (holotype with 11) sensory pits. Brachypterous, with reticulated venation. Legs simple; with carinae and setae; tibia III with single median spine.

ABDOMEN. Terga without longitudinal carinae. Tergite III ( Figs 3F View Fig , 26B View Fig ) without sensory pits. Tergite IV ( Figs 3F View Fig , 26B View Fig ) with one row of three to five sensory pits followed by single isolated ventral one. Tergites V to VII ( Figs 3F View Fig , 26B View Fig ) with one row of three to four (holotype and allotype with three to four) sensory pits followed by isolated ventral pair aligned diagonally ( Fig. 26B View Fig ). Tergite VIII ( Fig. 26B View Fig ) with one sensory pit.

MALE TERMINALIA. Pygofer ( Fig. 4A View Fig ) narrow, with anterior margin deeply concave; posterior margin almost straight. Connective ( Fig. 4B View Fig ) inverted Y-shaped, with support bridge with dorsal flap. Style ( Fig. 4 View Fig C–D) hook-like; anterior portion pointed; posterior portion strongly curved anterodorsally ( Fig. 4D View Fig ), converging towards the other in dorsal view ( Fig. 4C View Fig ); dorsal margin ( Fig. 4D View Fig ) with slight protuberance on median third; ventral margin ( Fig. 4D View Fig ) with concavity on anterior third, remainder rounded; middle portion ( Fig. 4D View Fig ) almost as long as high, setose; apex serrated ( Fig. 4D View Fig ). Phallobase ( Fig. 4 View Fig E–H) sclerotized, symmetrical, with two defined lobes; apex with pair of lobes curved ventrally in lateral view ( Fig. 4 View Fig G–H); apices of lobes truncate in dorsal view ( Fig. 4 View Fig E–F), surrounding aedeagus from middle third.Aedeagus ( Fig. 4 View Fig E–F) apex narrow and open dorsally, with pair of hooks, both curved ventrad and anterolaterally, but one positioned more dorsally than other. Suspensorium V-shaped. Segment X of anal tube ( Fig. 4 View Fig I–J) as long as wide; posterior margin ( Fig. 4I View Fig ) rounded; setose.

FEMALE TERMINALIA. Posterior margin of sternite VII ( Fig. 5B View Fig ) with median portion slightly produced, setose. Gonoplac ( Fig. 5C View Fig ) sclerotized, sub-rectangular with apex truncate, setose. Anterior connective lamina of gonapophysis VIII ( Fig. 5D View Fig ) with three apical teeth: innermost larger than outer ones, narrow and long, middle one widest, outer one short and apically rounded; middle and outer ones closer to each other than to inner one. Posterior connective lamina of gonapophysis IX ( Fig. 5 View Fig E–F) distal part with longitudinal row of ten to twelve short and triangular spines in lateral view ( Fig. 5F View Fig ); middle portion with several pits ( Fig. 5F View Fig ); apex setose ( Fig. 5F View Fig ). Segment X of anal tube ( Fig. 5 View Fig G–H) longer than wide at widest portion; posterior margin ( Fig. 5G View Fig ) pointed with apex rounded; setose.

Remarks

This species was identified based on comparisons with the type series (holotype and allotype) from Texas ( USA) and the original description by Metcalf (1923) plus the redescription by Doering (1939), which do not include the arrangement of abdominal sensory pits or female terminalia. Previously published illustrations of the dorsal view of the body and lateral view of the head allow comparison of the sensory pits of the sides of the frons and the lateral lobe of pronotum to those of other species. The male terminalia were previously illustrated superficially, but the overall shape could also be compared. Two recently collected available specimens have four sensory pits on each lateral lobe of pronotum ( Fig. 3C, F View Fig ), which is different from the three sensory pits illustrated by Metcalf (1923) and Doering (1939). Both specimens of the type series have three pits on the right side, but the female allotype has four pits on the left side. A series of several additional specimens from Mexico (see Material examined above) includes one additional male and female with three pits on one pronotal lobe and four on the other; the remaining specimens have three pits on both lobes, as in the holotype, and their genitalia match those of other studied specimens of this species. The holotype of Bruchomorpha decorata var. nihldecorata Caldwell, 1945 also has four pits.

Finally, this species is firstly recorded from Panama.
