9. Otostigmus (Parotostigmus) gemmifer Attems, 1928a

( Figs 15–17 )

Material examined. Cameroon: Tinta , Assumbo, Mamfe distr., 4/4/1933 (137L, 168 IN), 2350’, Percy Sladen Expedition, leg. I. T . Sanderson, 1 ex., BMNH ?; Cameroon: Mamfe , Mamfediu, 550’ (109L, 119 IN), 17/2/1933 and 3/3/1933, in dead logs, under stones, Percy Sladen Expedition, leg. F.J. Sanderson, 1 ex., BMNH ?; Nigeria: Nko , Obubra div., S . Nigeria, 500 ft, 28/6/1933 (249 s, 385 in), Percy Sladen Expedition, leg. F.J. Sanderson, 1 ex., BMNH ?. ( Fig. 8 ).

Type locality. Cameroon ( Maconje farm, Mungo river) ( Minelli et al. 2006) .

General distribution. West-Central Tropical Africa: Cameroon ( CM) ( Minelli et al. 2006); Nigeria ( NG) (new region record).

Remarks. The two specimens from Cameroon studied here compare to the original description as follows (Attems’ character state in parentheses): 2.5 glabrous antennal articles [2.33]; 4+4 or 3+5 teeth on the coxosternal tooth plates (in the latter case with the inner two pairs grouped); paramedian stutures complete from T8 [T7]; paramedian sutures confined to the anterior part of sternites; no coxopleural process; two tarsal spurs on legs 1–3 [4–5]; one tarsal spur to leg 19. A specimen from southern Nigeria ( Figs 15–17 ) agrees with the Cameroon specimens in all details, including 2.5 glabrous articles, paramedian sutures complete from T7, the same shape of the sternite of the ultimate leg-bearing segment and coxopleuron ( Fig. 17 ), and one tarsal spur from at least leg 4 (legs 1–3 missing) to leg 19.
