Neohirasea bispina babeensis subsp. nov. ( Figs 11–12 , 50 )

Diagnosis. This new subspecies is similar to the nominate N. bispina bispina sp. nov. & subsp. nov., but can be separated by larger size, longer lateral spines on mesonotum, paired spines on median segment and two supra-coxal spines on metapleurae.

Description. Male. Body slender and long. Head and antennae as in nominate race. Thorax with a few small granules. Pronotum rectangular, longer than wide, anterior margin nearly truncate, posterior margin rounded; transverse and longitudinal sulci crossing before middle area, with a pair of spines on anterior margin, apices pointing forwards. Mesonotum elongate, more than 3 times as long as pronotum, gently expanded posteriorly; median longitudinal carina indistinct, with paired spines anteriorly, post-medially and posteriorly, also with a pair of short mediolateral spines, lateral margins with a few spines. Mesopleurae with a spine near posterior area and a supra-coxal spine. Metanotum longer than median segment, with paired spines post-medially, lateral margins with a short spines post-medially. Metapleurae with a medial spine and 2 supra-coxal spines. Median segment rectangular, longer than wide, with paired spines post-medially. Eighth tergum almost as long as ninth tergum. Anal segment longer than ninth tergum, with a broad V-shaped emargination on posterior margin. Poculum cup-shaped, posterior margin rounded and reaching anterior margin of anal segment. Cerci and vomer as in nominate race. Legs as in nominate race.

Female. Unknown.
