Redescription of male: The original description and the description of Rehn (1933) can be supplemented with the following details. Most surfaces of body (head, pronotum, tegmina and abdomen) smooth and lustrous, distal parts of antennae (approximately from 15-16 th segments) dull; very weak punctuation present in vertex, facial part of head, pronotum and proximal parts of tegmina, especially in costal field. Head about as long as wide or slightly wider than long ( Fig. 1 View Figs 1 - 15 ); ocellar spots small; facial part globular, without impression or wrinkles between eyes; distance between eyes 0.7-0.9 times eye length; distance between antennal sockets about 1.7-1.9 times scape length (0.8 - 1.0 mm); approximate length ratio of 3 rd- 5 th segments of maxillary palps 1.2: 1.0: 1.2. Pronotum as in Fig. 2 View Figs 1 - 15 . Tegmina and wings completely developed, surpassing abdominal apex. Tegmina with rounded apex, coriaceous in proximal and membranous in distal parts; venation subobsolete in about proximal fourth, distinct in distal half; costal field long and narrow; Sc thickened (well visible on ventral side of tegmen) with 1-4 apical branches; R, M and CuA stems not separated basally; CuP distinct. Wings mostly membranous, with only weakly sclerotized area of anterior rami of R; Sc long and simple; RA long, with slightly incrassated anterior veins; RS weak; M long and simple; CuA pectinate with 4-5 complete (reaching wing margin) veins; behind CuA a long and simple vein, probably corresponding to 1 st plical vein sensu Rehn (1951) or CuP [probably CuP + A 1 sensu Bey-Bienko (1950)]; next long and simple vein probably corresponds to 3 rd plical vein sensu Rehn (1951); between 1 st and 3 rd plical veins at base of wing located sclerotized field with short reduced vein, probably corresponds to 2 nd plical vein sensu Rehn (1951); anal fan consisting of 16-17 veins reaching margin of wing; 2-3 possibly jugal veins situated behind anal fan. Fore tibiae not thickened distally. Anterior margin of fore femora of armed type B, with 5-7 spines, including 2 apical one. Tibial spines well developed. Structure of hind tarsi: metatarsus about as long as other segments combined; euplantulae of 1 st- 4 th segments small and apical; metatarsus with 2 more or less equal rows of spines along lower margin; “additional spines” bordering euplantulae of 2 nd- 3 rd segments from inside and outside present; claws symmetrical, very weakly serrated; arolium distinct, about as half as claw length. Abdomen with 1 st tergite specialized ( Fig. 3 View Figs 1 - 15 ): small cone-shaped tubercle ( Fig. 3 View Figs 1 - 15 , tub.) situated in medial hollow, the anterior part of this tubercle densely covered with hair. First and, in lesser degree, following abdominal tergites with membranous strip along caudal margin ( Fig. 3 View Figs 1 - 15 ). Anal plate (tergite X) short and transverse, nearly rectangular, caudal margin weakly concave, without medial incision ( Figs 4, 6 View Figs 1 - 15 ); three small more or less expressed bulges located at sides and in the middle of caudal margin of anal plate ( Figs 4, 5 View Figs 1 - 15 , bul.). Cerci with distinct segments. Paraprocts of blaberidtype ( Figs 4-6 View Figs 1 - 15 , par.). Hypandrium asymmetrical, caudal margin angularly projected caudally; right stylus cylindrical, left stylus absent ( Fig. 7 View Figs 1 - 15 ).

Genitalia ( Figs 8-15 View Figs 1 - 15 ). Right phallomere (R+N): sclerite R 1 T well sclerotized, serrated, caudal part of R 1 T in shape of separated large plate-like sclerite ( Figs 8, 9 View Figs 1 - 15 , pl.s.), lateral part of this sclerite probably correspond to sclerite R 4 ( Figs 8, 9 View Figs 1 - 15 , R 4?); bristles absent; R 2 slightly curved, without hollow; R 3 “V”-shaped, with long and thin branches; R 4 probably fused with large plate-like sclerite; R 5 large, well sclerotized, plate-like. Sclerite L 2 D (L 1) divided into basal and apical parts ( Figs 10, 11 View Figs 1 - 15 ); basal part rod-like, with outgrowth at caudal end ( Fig. 11 View Figs 1 - 15 , out.); “apical sclerite” small, thimble-like; bristles absent ( Fig. 11 View Figs 1 - 15 , ap.scl.). Sclerite L 3 (L 2 d) without basal subsclerite, “folded structure” and bristles present ( Figs 12-15 View Figs 1 - 15 , f.s.); apex of L 3 with attenuated “small tooth” ( Figs 13-15 View Figs 1 - 15 , s.t.); “apical crest” and groove hge absent. Sclerite L 4 U (L 3 d) distinct, plate-like ( Fig. 12 View Figs 1 - 15 ).

Redescription of female: Similar to male, but body slightly more robust and ovoid. Distance between antennal sockets of the head about 2.0 times of the scape length (0.9 -1.0 mm); approximate length ratio of 3 rd- 5 th segments of maxillary palps 1.0: 1.0: 1.1. Abdomen without visible glandular specializations. Anal plate (tergite X) trapezoidal, with distinct median incision on caudal margin ( Fig. 16 View Figs 16 - 23 ). Paraprocts medially membranous ( Fig. 18 View Figs 16 - 23 , par.). Genital plate as in Fig. 17 View Figs 16 - 23 .

Ovipositor and adjacent structures ( Figs 18, 19 View Figs 16 - 23 ): Intercalary sclerite absent; tergal processes of abdominal segment VIII not reaching paratergites of VIII tergite ( Fig. 18 View Figs 16 - 23 , teVIII.); tergal processes of abdominal segment IX completely developed ( Fig. 18 View Figs 16 - 23 , teIX.). Two rounded sclerites ( Fig. 18 View Figs 16 - 23 , l.scl.) situated lateral to paratergites. Gonangulum distinct, well sclerotized ( Figs 18, 19 View Figs 16 - 23 , gg.). First valves of ovipositor large and membranous at apex ( Fig. 18 View Figs 16 - 23 , v.I.), with setae (not shown in Fig. 18 View Figs 16 - 23 ) along inner side. Base of 2 nd and 3 rd pairs of valves as in Fig. 19 View Figs 16 - 23 . Anterior arch of second valvifer as in Fig. 19 View Figs 16 - 23 , aa. 2 nd valves of ovipositor small. 3 rd valves of ovipositor (gonoplacs) wide, partly membranous ( Fig. 18 View Figs 16 - 23 , v.III.). Basivalvulae weakly sclerotized, in shape of two slightly asymmetrical plates with reflexed outer margins ( Figs 18, 19 View Figs 16 - 23 , bsv.). Vestibular sclerite weakly sclerotized, horseshoe-like, with articulated lateral parts ( Figs 18, 19 View Figs 16 - 23 , vs.). Brood sac membranous, with indistinct weakly sclerotized medial plate ( Fig. 18 View Figs 16 - 23 , m.pl.).

Measurements (in mm): Head length: male 3.4-3.7, female 4.0- 4.2; head width: male 3.6-3.7, female 4.1-4.2; pronotum length: male 5.0, female 5.5-6.4; pronotum width: male 6.2-6.8, female 7.5-8.2; tegmen length: male 19.9-20.3, female 21.2-21.7; tegmen width: male 6.0- 6.5, female 6.7-7.6.

Note: This species was described from Cameroon ( Gerstaecker, 1883) in the genus Epilampra Burmeister, 1838   and transferred into the genus Rhabdoblatta Kirby, 1903   by Princis (1967). Africalolampra erubescens   is probably relatively frequent in West Africa ( Rehn, 1933).
