Anisyutkin, Leonid N., 2020, New and little known Epilamprinae (Dictyoptera: Blaberidae) from the collections of the Muséum d’histoire naturelle de Genève and the Zoological Institute of Saint Petersburg. Part 4, Revue suisse de Zoologie 127 (1), pp. 105-117 : 108-111

Molytria inquinata ( Stål, 1860)

Figs 21-24

Material examined: ZIN; 1 female; “ Australia, East Karajong [sic!], under log in bush; 7.VI.1959; M. Nikitin ”, “Australia Molytria inquinata Stal ”, genital complex in prep. 151119/01 . – ZIN; 1 female; Australia, Queensland, Brisbane ; 21.II.1969; leg. Plechanov.

The first label was written in Russian, with the exception of “East Karajong” and “under log in bush” which were given in English. “Karajong” is probably Kurrajong, a small town in New South Wales. The second label was all written in Russian.

Details: Head rounded; distance between eyes 0.8-0.9 times eye length; distance between antennal sockets about 1.8 times scape length (~ 1.3 mm); approximate ratio of lengths of 3rd to 5th segments of maxillary palps 1.0-1.1: 1.0: 1.4. Fore tibiae not thickened distally. Anterior margin of fore femora of type B armament, with 9 spines, including 2 apical one. Tibial spines well developed. “Additional spines” bordering euplantulae of 2nd to 3rd segments on inner and outer side present. Anal plate (tergite X) wider than long and widely rounded, with weak medial incision on hind margin ( Fig. 21 ). Cerci short and slender, with distinct segments ( Fig. 21 ). Genital plate wide, sinuate along hind margin ( Fig. 22 ).

Ovipositor and adjacent structures ( Figs 23-24 ): Paraprocts with isolated anterior sclerites ( Fig. 23 , a.Par.). Intercalary sclerite absent. Tergal processes of abdominal segment VIII short, not reaching paratergites of tergite VIII ( Fig. 23 , teVIII.); tergal processes of abdominal segment IX fully developed ( Fig. 23 , teIX.).

Gonangulum well sclerotized ( Figs 23-24 , gg.). All valves of ovipositor weakly sclerotized. First valves large, membranous at apex, with numerous setae along inner side ( Fig. 23 , v.I., setae not shown). Base of 2nd and 3rd pairs of valves as in Fig. 24 , sclerotized lobes well developed and elongated ( Fig. 24 , pl.). Anterior arch of second valvifer as in Fig. 24 , a.a. Second valves of ovipositor small, completely hidden under first valves. Third valves of ovipositor (gonoplacs) widened ( Fig. 23 , v.III.). Basivalvula in shape of slightly asymmetrical, widely rounded and partly sclerotized plate, partly divided medially ( Figs 23-24 , bsv.). Vestibular sclerite weakly sclerotized, with long lateral branches ( Fig. 23 , vs.). Brood sac ( Fig. 23 , bd.s.) with distinct wider than long sclerite ( Fig. 23 , s.bd.s.).

Measurements (in mm): Head length 5.2-5.4, head width 5.0-5.3; pronotum length 8.0-8.5, pronotum width 12.0-12.5; tegmen length 11.5, tegmen width 9.0.
