Gymnoproctus spec.

Only one male and one female were obtained from this new species. Oddly, the male is very small in body size. The posterior part of the pronotum is inflated. As in G. rammei the lateral sides are armed with long and slender spines. Also, the female is comparatively small, smaller than females of the morphologically similar G. rammei . G. similis occurring in the Singida area is similarly stout and large as G. rammei but has a less spiny pronotum, the spines having a rather stout base.

Material examined: 1 male, 1 female [CH7953 (SR, TI, CHR), CH 7954], TANZANIA, East Chenene Forest Reserve , Dodoma Region, March 2015, leg. C. Hemp.

Bioa coustics. The calling song ( Fig. 7F ) is quite similar to that of G. rammei and consists of long series of syllables (song type B in Fig. 5 ; see Table 2 ).

Genitalia. Judging from one specimen, the titillator may be similar to that of G. sculpturatus , being triangular ( Fig. 9J ).

Chr omosomes: 2n = 27 (26 + X0), FN = 28 (1 male); do not show differences to G. rammei ( Fig. 12H ).

FIGURE 12. Examples of chromosome number and heterochromatin C-banding of mitotic male (A–C, G–K) and mitotic female complements (D), as well as diplotene/diakinesis (C, E, I on the right), and metaphase I (F) for the following Hetrodini taxa: A Cosmoderus femoralis, 2n = 24 + X0 (CH8626), B Enyaliopsis bloyeti, 2n = 28 + X0 (HE114), C Enyaliopsis carolinus, 2n =24 + neo-XY (CH8625), D Enyaliopsis ephippiatus, 2n = 26 + XX (female CH7849), E Enyaliopsis jennae, 2n = 26 + neo- XY (HE87), F Enyaliopsis spec. 2 Mpwapwa, 2n = 26 + X0 (CH8353), G Gymnoproctus rammei, 2n = 26 + X0 (CH8763), H Gymnoproctus spec., 2n = 26 + X0 (CH7953), I Spalacomimus magnus, 2n = 16 + X0 (CH7945), J Spalacomimus verruciferus, 2n = 22 + neo-XY (CH7897), K Spalacomimus spec. near verruciferus, 2n = 22 + neo-XY (CH7899). Bi-armed chromosomes (meta/submeta/subacrocentric) are marked with numbers (A, C, D, F–I); in the neo-XY system, sex chromosomes form association in diplotene (C) and metaphase I (I); arrowheads indicate interstitial C-bands in 1 (A, E, J, K) and 2 (I) pairs; asterisks (*) marked distal C-bands in 3, 4, 5 (C), 3, 4 (D), 2-heteromorphic (G, H) pair; X = neo-X and Y = neo-Y sex chromosomes.
