Pseudocalolampra inexpectata Roth & Princis, 1971

Figs 7 , 66-84

Material examined: MHNG; 2 males (genital complex of one male in prep. 250317/01); Kenya, Mombasa, Leisure Lodge ; 6.- 10.06.1980; coll. C. Schomo. – MHNG; 1 male; Kenya, “ Leisure L. Jioni Gerch ” (handwritten illegible text); 4.06.1981; coll. C. Schomo. Remarks : The original description ( Roth & Princis, 1971) can be supplemented with the following details, based on specimens listed above. The holotype (not examined) of this species is kept in Natural History Museum of London .

Somatic characters of male: General colour yellowish brown, with scattered black dots. Colouration of head as in Fig. 7 , eyes black, facial part of head with large black or dark brown spot between eyes. Scapi and about 8-10 proximal segments of antennae yellowish, distal part greyish. Rest of head, mouthparts, legs, thorax and abdomen seen from below dirty yellow. Surfaces smooth and lustrous, head and pronotum with distinct transverse wrinkles ( Figs 7 , 66-67 ), weak punctuation present on pronotum. Head wider than long, with large impression between eyes and antennal sockets ( Figs 7 , 66 ); ocellar spots large; distance between eyes about as long as eye length; distance between antennal sockets about 2.3-2.7 times scape length (~ 0.6-0.7 mm); approximate length ratio of 3rd-5th segments of maxillary palps 1.1-1.2: 1.0: 1.0. Pronotum as in Fig. 67 . Tegmina and wings completely developed, surpassing abdominal apex. Tegmina with rounded apex, sclerotized in costal field; venation slightly reticulate; costal field long, about one third of tegmen length, and narrow; Sc thickened (well visible on ventral side of tegmen); R, M and CuP basally fused; CuP long, about one half of tegmen length. Wings membranous, only with weakly sclerotized area of Sc and anterior rami of R. Fore tibiae distinctly thickened distally ( Fig. 68 ). Anterior margin of fore femora of armed type B, with 4 spines, including 1 apical one ( Fig. 68 ). Tibial spines well developed. Structure of hind tarsus ( Figs 69-72 ): metatarsus a little longer than other tarsal segments combined, with 2 unequal rows of spines along lower margin: exterior row ( Fig. 71 , e.r.) consisting of 31-37, interior row ( Fig. 71 , i.r.) of 16-23 spines; 2nd and 3rd segments with 10-13/5-8 and 6-9/3- 5 spines in exterior and interior rows, respectively; other segments without spines along lower margin; very small euplantulae present on 3rd-4th segments; distal ends of 1st-4th segments bordered with 6, 5 and 3 “additional spines, respectively ( Figs 70-71 , a.s.); 1-3 large spines located on lateral sides of metatarsus ( Fig. 71 , l.s.); interior rows of spines displaced laterally on all segments; claws symmetrical, simple; arolium distinct, about half as long as claw ( Figs 69-72 ). Fore ( Fig. 69 ) and mid ( Fig. 70 ) tarsi dissimilar to hind tarsi: metatarsal euplantulae large, spines along lower margin absent; one pair of “additional spines” present only on 1st-2nd segments of mid tarsi. Abdomen without visible glandular specializations; spiracle-bearing outgrowths of tergite VIII weakly expressed, without attenuate posterolateral angles. Anal plate (tergite X) wider than long, with nearly straight hind margin ( Fig. 73 ). Cerci robust, with distinct segments ( Fig. 73 ). Left and right paraprocts with hook-shaped caudomedial process ( Figs 74-75 , par.). Hypandrium asymmetrical, hind margin between styli projected and rounded ( Figs 76-77 ); right stylus slender and cylindrical, left one vestigial or absent.

Male genitalia ( Figs 77-84 ): Right phallomere ( R +N): caudal part of sclerite R 1 T thin and weakly sclerotized ( Fig. 78 , c.p. R 1T ), cranial part widely rounded ( Fig. 78 , cr.p. R 1 T); R 1 T densely covered with bristles; R 2 rounded; R 3 long, with cranial part rodlike and caudally forked; R 4 only partly sclerotized; R 5 elongated. Sclerite L2D (L1) divided into basal and apical parts ( Figs 77, 79-80 ); basal part robust, distinctly widened cranially ( Figs 77, 79-80 , b.L 2D ), with large “bent outgrowth” at caudal end ( Figs 79-80 , b.o.), “additional sclerite” under basal part of L2D large ( Figs 77, 79 , a.scl.); apical part in shape of flattened, plate-like sclerite ( Figs 77, 79-81 , ap.scl.), with upwardcurved “apical tooth” ( Figs 79-81 , ap.t.); bristles absent. Sclerite L3 (L2d) with basal subsclerite ( Fig. 77 , b.L 3 ); “folded structure” and bristles absent; apex of L3 with “small tooth” ( Figs 82-84 , s.t.); groove hge absent. Sclerite L4U (L3d) large ( Fig. 77 ).

Dimensions (in mm): Head length 2.8-3.1, head width 3.0-3.2; pronotum length 4.5-5.0, pronotum width 6.5- 7.2; tegmen length 17.2-18.0, tegmen width 5.5-6.1.
