http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile. org:TaxonName:492600

Holotype male (in alcohol). Tanzania, Lindi Region, Lindi District, Litipo forest reserve, 39° 29′ E 10° 02′ S; July– November 1991, leg. FRONTIER Tanzania. Depository ZMUC.

The holotype is unique.

Description Male. The only specimen known from this species is stored in alcohol and discolored. The stridulatory area of the left tegmen is brown suggesting a similar color pattern as in other Parapyrrhicia species ( Fig. 4 ). Head and antennae: Antennae thin surpassing flexed wings by about ½ cm. Fastigium as for genus. Eyes circular, prominent, dark in holotype. Thorax: Pronotum without lateral carinae, surface smooth. Tegmina and wings: Both pairs of wings fully developed, alae surpassing tegmina. Stridulatory area of left tegmen as in Fig. 16c . Stridulatory file as in Fig. 16d with 75 teeth. Fore and mid femora with anterior ventral row of seven to eight spines along whole length, unarmed on posterior side. Hind femora with seven to eight tiny spines ventrally on anterior side. Fore and mid tibiae one tiny spur on posterior side and two tiny spurs on anterior side. Hind tibiae with two apical spurs on each side and four rows of numerous small spinules getting denser distally. Abdomen: Tenth abdominal tergite posteriorly produced with down-curved process medially ( Fig. 16a, e ). Cerci stout differentiated into two branches separating midway. Inner branch of cercus little expanded and curved with sclerotized tip ( Fig. 16c ), outer branch of about same thickness and length also with sclerotized rounded tip ( Fig. 16a, b, e ). Subgenital plate elongated, halfway cut into two lobes leaving oval gap ( Fig. 16b ). Titillator short, just to be seen between subgenital plate and cerci, acute and sclerotized.
