3. Serratitibia lividipes (Mulsant) , new combination

Cleothera lividipes Mulsant, 1853: 82 .

Hyperaspis lividipes: Korschefsky 1931: 191 ; Iablokoff-Khnzorian 1972: 171.

Description. Male lectotype. Length 2.5 mm, width 2.0 mm; body rounded, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with short, narrow, black, basomedial macula, anterior margin of macula indented medially, extended anteriorly 1/5 distance to pronotal apex at middle; elytron black with 5 large, yellow spots arranged in transverse rows of 2 each plus apical spot, lateral margin with humeral, mediolateral, and apical spots broadly connected, discal spot small, almost round, apical spot large, transversely oval ( Fig. 73 ); meso–, metaventrites reddish brown; abdomen yellow. Head punctures small, separated by less than diameter, each puncture as large as an eye facet; pronotal punctures equal in size to head punctures, separated by less than 2 times diameter; elytral punctures larger than pronotal punctures, separated by 1–3 times diameter; metaventral punctures larger than on elytra, separated by about diameter medially, larger and separated by less than diameter laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, angled forward, apically acute, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin rounded, basal margin without bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin straight, with about 12 teeth, teeth small except median 2 teeth large, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at base of prosternum. 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 angled to posterior ventrite margin, flat along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 3 ventrites large, separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5 th ventrite depressed medially in apical 1/2, apical border weakly emarginate medially, lateral angle of emargination pronounced with small tubercle bearing tuft of dense setae; 6 th ventrite narrow, deeply depressed medially, depression glabrous, without median tubercle, apical margin broadly, shallowly emarginate, angle on each side of emargination broadly rounded. Apical tergite short, narrow, apex feebly rounded, nearly truncate, surface densely, finely punctured. Genitalia with basal lobe 2/3 length of paramere, sides nearly parallel, apex rounded; paramere Unm type, widened apically, apex rounded ( Fig. 74, 75 ); sipho robust, curved in basal 1/2, basal capsule small, inner arm short, apex rounded, outer arm wide, 3 times wider than inner arm, with accessory piece, basal border weakly emarginate ( Fig. 76, 77 ).

Female. Unknown.

Variation. Length 2.5–2.60 mm. Paratypes with humeral and mediolateral spots broadly connected, apical spot discrete.

Type locality. “Cayenne” ( French Guiana).

Type depository. ZMMU (lectotype here designated).

Geographical distribution. French Guiana, Venezuela.

Specimens examined. 3. French Guiana. The lectotype labeled “Cayenne;” Venezuela. Venezuela Exp., Territ. Amazonas, Upper Cunucunuma , Taparal .; Bolivar, Carr. Sta. Elena De V. - Pau ??, 11-IX- 1977, B. Bechyné leg. ( MIZA) ( USNM) ( ZMMU) .

Remarks. This species has the appearance of a miniature S. donna . The lateral margin with humeral, mediolateral, and apical spot broadly connected, or at least the humeral and mediolateral spots broadly connected, and lack of setal tufts on either the metaventrite or basal abdominal ventrite will help to distinguish S. lividipes . Despite the color difference between the lectotype and the Venezuelan specimens, this is considered a single species because male genitalia are consistently the same in all specimens examined.

Mulsant described both male and female specimens, the male in the ZMMU labeled “ Cleothera lividipes (handwritten)/ Cleothera lividipes Muls, Cayenne (green label, hand written)/ Holotypus Hyperaspis lividipes Muls. (red paper)”, is here designated the lectotype. The holotype label attached in 1972 by S. M. Khnzorian is clearly invalid.
