Description. Male lectotype. Length 2.4 mm, width 1.9 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, black basomedial macula having anterior border indented with yellow, extended nearly 3/4 distance to anterior pronotal border; elytron with apical 1/5 dark brown, apex of apical spot ragged ( Fig. 332 ); ventral surface with median 1/3 of meso–, metaventrites brown; abdomen entirely yellow. Head punctures small, separated by less than diameter, each puncture about as large as an eye facet; pronotal punctures equal in size to head punctures, separated by 1–3 times diameter; elytral punctures larger than on pronotum, separated by less than 2 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin straight, basal margin without trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange slightly narrower than remainder of protibia, outer margin arcuate in basal 1/2, straight in apical 1/2, with several small teeth in basal 1/2 and a single, large median tooth at apex of flange, sponda large, extended far beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/4 of prosternum, joined to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite rounded to posterior ventrite margin, slightly flattened along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 2 ventrites large, separated by less than 2 times diameter, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5th ventrite depressed medially in apical 1/2, apical border weakly emarginate medially, lateral angle of emargination with small tubercle bearing tuft of dense setae; 6th ventrite narrow, depressed medially, depression glabrous, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination with tuft of setae. Apical tergite short, narrow, apex feebly rounded, surface densely, finely punctured. Genitalia with basal lobe nearly as long as paramere, sides convergent, apex rounded; paramere Unm type, wide, widened apically, apex rounded ( Fig. 333 ); sipho robust, curved in basal 2/3, basal capsule with inner arm short, apex irregularly rounded, outer arm 3 times longer than inner arm, not widened apically, with accessory piece, basal border broadly, moderately emarginate ( Fig. 334 ).

Female. Similar to male except head entirely black with anterolateral angle yellow, black pronotal area extended to anterior margin medially. Genitalia with spermatheca long, slender, curved medially, cornu enlarged; bursal cap broadly triangular, with 3 arms, inner arm faint, apical strut short, narrow, apex weakly spatulate in lateral view ( Fig. 335 ).

Variation. Length 2.4–2.7 mm, width 1.9–2.0 mm.

Type locality. Volcan de Chiriqui, Panama.

Type depository. BMNH (lectotype validated by Almeida and Milléo 2000).

Geographical distribution. Brazil, Panama.

Specimens examined. 3. Brazil. Minas Gerais; Camanducaia (Vila Monte Verde) ; Santa Bárbara ( Serra do Caraca ) . Panama. V. de Chiriqui, 2-3000 ft. (type series). ( MZNSP) ( BMNH) .

Remarks. This species was described from Panama, but was also found to occur in Brazil ( Almeida and Milléo 2000). It has a dorsal color pattern thus far unique among known species of Serratitibia . It was placed in Hinda by Almeida and Milléo (2000), but is a typical example of Serratitibia .

The type series consists of 6 specimens that actually represent examples of two different species having nearly identical color patterns. The first 3 specimens are considered D. terminata , the second 3 specimens represent another Serratitibia species with radically different male genitalia. The second species is not known to occur in South America. Almeida and Milléo (2000) validated a lectotype first labeled as that by Gordon in 1970, but not published. All remaining specimens bearing labels identical to the lectotype (except for blue bordered “ syntype ” labels) are here designated as paralectotypes.
