Figs 36-52

Notolampra lucida Saussure, 1862

Phoraspis cassidea Burmeister, 1838 (nec Dalman, 1823)

Material examined: MHNG; 1 male; “ Bahia, Brésil; M H de Saussure”, “ Thorax cassidea ♂ Burm. ” . – ZIN; 1 female; Brazil, “ Aqua Preta 22.9.936”, “2247”, “ Notolampra gibba Thnb. ” . – ZIN; 1 female; “ Bahia ”, “ Notolampra gibba, Thunb. = cassidea, Burm. ” / “ Phoraspis cassidea Burm. ” (The crossed out identification is written on the back of the label), “ R. Shelford det.” .

Redescription of male ( Figs 36-48 ): General colour dirty yellow, head, pronotum and tegmina with scattered black dots ( Fig. 37 ), middle legs, coxae of hind legs (other parts of hind legs missing) and ventral side of abdomen blackish. Surfaces smooth and lustrous; antennae with lustrous proximal 10-13 segments, other segments dull; head with large sparse punctuation, pronotum and, to a lesser degree, tegmina with fine dense punctuation. Head wider than long, epicranial sutures absent ( Fig. 36 ); ocellar spots small, weakly expressed; distance between eyes about 1.1 times eye length; distance between antennal sockets about twice scape length (0.8 mm); approximate ratio of lengths of 3rd to 5th segments of maxillary palps 1.0: 1.0: 1.1. Pronotum as in Fig. 37 . Tegmina and wings completely developed (left tegmen missing), surpassing abdominal apex. Tegmina strongly sclerotized and convex, venation strongly reduced ( Fig. 37 ), in distal half better developed than in proximal half; area of right tegmen overlapped by left one at rest and distinctly reticulate. Anterior margin of fore femur armed as in type B, with 2-4 spines, including 1-2 apical ones. Fore tibiae not thickened distally. Hind and left mid legs broken off. Structure of mid tarsi: metatarsus half as long as other segments combined, with large euplantulae along lower margin; euplantulae of 2nd to 4th tarsal segments large; spines absent; claws symmetrical and simple; arolium large, slightly shorter than claw. Fore tarsi similar to mid tarsi, but segments relatively shorter. Abdominal tergites without visible glandular specializations; posterolateral angles of tergites attenuate and sharp. Anal plate (tergite X) elongated, with large median incision ( Fig. 39 ). Cerci shortened and flattened ( Fig. 39 ). Paraprocts of blaberid-type ( Fig. 40 ). Hypandrium elongated and asymmetrical ( Fig. 41 ), with membranous area along right margin; styli asymmetrical and cylindrical.

Male genitalia ( Figs 42-48 ): Right phallomere (R+N): caudal part of sclerite R1T well sclerotized, enlarged ( Figs 42-43 , c.p.R 1T ), dorsally with large and medially sclerotized “upper triangular lobe” ( Fig. 42 , tr.l.) densely covered with bristles; R2 curved, with weakly expressed hollow; R3 short and robust, widened caudally; R4 platelike; R 5 in shape of large weakly sclerotized lobe, fused with R2. Sclerite L2D (L1) divided into basal and apical parts ( Fig. 44 ); basal part strongly widened cranially; apical part in shape of flattened and curved plate ( Figs 44-46 ), “dorsal outgrowth” and bristles absent. Sclerite L3 (L2d) with basal subsclerite ( Fig. 47 , b.L 3 ); “folded structure” distinct, with short bristles ( Figs 47-48 ); apex of L3 attenuated; groove hge present. Sclerite L4U (L3d) small, very weakly sclerotized.

Redescription of female ( Figs 49-52 ): Similar to male, but larger, more robust and more convex. Facial part of head with scattered black dots, eyes black. Head with distance between eyes 1.2 times eye length; distance between antennal sockets about 1.8 times scape length (~ 1.2-1.3 mm); approximate ratio of lengths of 3rd to 5th segments of maxillary palps 1.1-1.2: 1.0: 1.1-1.2. Tegmina with venation nearly indistinct, main veins (Sc, R, CuP) visible as indistinct swellings. Anterior margin of fore femur armed as in type B, with 3-5 spines, including 2 apical ones. Anal plate (X tergite) triangular in shape, with distinct median incision ( Fig. 49 ). Paratergites of tergite IX large and plate-like ( Fig. 51 ). Paraprocts fused with anal plate, tapered and sclerotized caudally ( Fig. 51 ). Genital plate as in Fig. 50 .

Ovipositor and adjacent structures ( Figs 51-52 ): Intercalary sclerite absent. Tergal processes of abdominal segment VIII small and fused with tergal processes of abdominal segment IX, the latter fully developed ( Figs 51-52 , teIX.). Gonangulum well sclerotized ( Fig. 52 , gg.), fused with well developed sclerotized lobes ( Fig. 52 , pl.). First valves of ovipositor large, partly membranous, with setae along inner side ( Fig. 52 , v.I., setae not shown). Second valves of ovipositor small, completely hidden under first valves ( Fig. 52 , v.II.). Third valves of ovipositor (gonoplacs) wide ( Fig. 52 , v.III.). Basivalvula in shape of transverse arch-like plate ( Fig. 52 , bsv.). Vestibular sclerite in shape of thin and curved strip ( Fig. 52 , vs.). Brood sac without sclerotized structures.

Measurements (in mm): Head length: male 3.1, female 4.6-4.9; head width: male 3.3, female 4.3-4.6; pronotum length: male 4.5, female 6.2-6.7; pronotum width: male 6.1, female 8.5-9.2; tegmen length: male <16.0 (apices of tegmina and wings broken), female 19.5-20.5; tegmen width: male 6.0, female 9.0-9.5.

Remarks: The specimens described above and the specimen determined as N. gibba in a paper by Roth (1971) have different shapes of the apical part of sclerite L2D ( Figs 44-46 cf. Roth, 1971: fig. 27). This can be explained by different angles of view, or the specimens may belong to different species.

The descriptions of ovipositor and adjacent structures are incomplete due to insufficient conspecific material. Note that in Fig. 52 the ovipositor is in such a position that the third valves cover the first and second ones. Only two females of this species were at the disposal of the author. One of them has a missing abdomen, while the other has damaged genitalia ( Figs 51-52 ).
