Aristobatina morogoro Marshall 2014, sp. n.

Aristobatina morogoro sp. n. Figs 7–11, 24–26 Etymology: The specific epithet refers to the region in which all type material was collected. Description: Length (head to wing tip): 13 mm. Colour: Head orange anteriorly, reddish brown posteriorly, swollen part of frontal vitta dark reddish brown; body black; fore femur orange basally and brown distally; mid and hind femora black in basal ⅔, orange in distal ⅓; basal 2 tarsomeres of fore leg white, other tarsomeres black; abdominal pleurae mostly white, darkened with dark microsetulae on segments 1–2, with an elongate, oval, convex and differentiated area just below tergite 1–2 in male. Head: Scape bare, except for marginal row of short setae; pedicel short­setose, with 3–5 longer, distal, ventral setae; face membranous and narrow; lower ½ of frons orange, swollen part of frontal vitta teardrop­shaped, dark reddish brown, surrounding ocelli, separated from anterior margin of frons by more than its length; 2 pairs of fronto-orbitals, 1 very large posterior pair at level of ocelli and a very small anterior pair at midpoint of vitta; postocellar, outer and inner vertical setae well­developed. Thorax: Cervical sclerite of females flat and dull, with lateral indentation and small anterolateral vertical carina; males have a slightly convex cervical sclerite, without indentation; proepisternum with a few long, marginal ventral setae in posterior ½; katepisternum with double row of thin black setae, anterior row of 8 setae lower than posterior row; scutellum with 1 pair of marginal setae and 4 small dorsal setae; with small but distinct seta between postalar and dorsocentral setae. Wing: CuA 2 virtually at right angle to and in line with bm­cu; wing membrane dark, with broad discal fascia extending from R 4+5 to Cu, and an apical infuscation; tegula and basicosta dark brown, similar to adjacent wing base, which has 3 long costagial setae, inner one very long and inclinate. Female abdomen: Spermathecae oblong, 2.1× as long as wide, with transverse striations, spermathecal duct densely covered with knob­like processes beyond the division of the common duct into two straight branches. Single spermatheca uniformly studded. (Fig. 15). Male abdomen: Pleuron with large, dome­like, differentiated area on segment 4; hypandrium with elongate anterior plate and strong posterodorsal arms connecting to phallic plate, dorsolateral margin of posterodorsal arm having a prominent spur (Fig. 7). Basiphallus elongate, extending well beyond base of distiphallus; postgonites equal and unmodified (Fig. 9); distiphallus with tubular basal part bifurcating before transition into strongly recurved membranous distal part, apex with a finely spinulose glans (Fig. 8); ejaculatory apodeme about ⅓ as large as epandrium (Fig. 7); genital fork (sternite 5) with gap T­shaped at base (Fig. 11), inner surfaces of arms densely spinose. Holotype ♂: TANZANIA: Morogoro Region, Udzungwa Mts Nat. Park, 07°50'35''S 36°49'49''E, 11–13. xi.2009, 1000 m, T. Pape & S. A. Marshall (ZMUC). Paratypes: 2♂ 2♀ same data as holotype (ZMUC, DEBU). Comments: Although this species is externally very distinct from previously described Aristobatina, the remarkable male and female internal terminalia and the unusual membranous dome on male pleuron 4 indicate that it belongs in a monophyletic Aristobatina.
