ETYMOLOGY. — Species name melanocephala refers to its black head. Chinese name: 黑头ũ须蟋.

DIAGNOSIS. — Almost uniform dark brown. Head of the new species dark brown (lower half of head lighter in other species). Hind wings obviously longer than forewings ( Fig. 8A View FIG ), comb of tegminal Sc with 6-7 branches. Darkened bases of spines of hind tibiae ( Fig. 4B View FIG ). This species resembling M. tianya He & Wei n. sp. based on genitalia, but pseudepiphallic lophi without projections apically.

DISTRIBUTION. — China (Guangdong, Guangxi, Yunnan).

DESCRIPTION

Male

Head. Vertex broad and flattened. Head wider than the anterior margin of pronotum; frontal rostrum convex, densely pubescent ( Fig. 2C, D View FIG ). Median ocellus smallest of the three ocelli, ovoid ( Fig. 6B View FIG ); lateral ocelli larger and flatter than middle one, transversely ovoid. Eyes strongly prominent and large, about half head length.

Thorax. Pronotum broad, finely pubescent; posterior margin longer than anterior; anterior margin straight and posterior slightly convex; two eyelike spots of pronotum disc distinct and smooth ( Fig. 8A View FIG ). Longitudinal veins of forewings parallel, costal area of tegmina with only a few crossveins irregularly situated between branches of Sc. Forewings obviously shorter than hindwings, uncovered portion shorter than hind femur, comb of tegminal Sc with 6-7 branches. Distal half of forewings usually with small darkish spots around crossveins.

Legs. Only inner side of fore tibia with elongate-ovoid tympanum, pitted ( Fig. 3C, D View FIG ). Hind tibiae serrulated, with short and thin spines among subapical spurs, sparser as closer to the apex (os5-os4:3, os4-os3:3, os3-os2:1, os2-os1:0; is6-is5:3, is5-is4:1, is4-is3:1, is3-is2:0, is2-is1:0); with six inner and five outer subapical spurs; three inner and three outer apical spurs, outer spurs short (the middle one longer; the other two equal in length) and the inner spurs long (superior one longest, inferior one shortest) ( Fig. 4B View FIG ).

Male genitalia. Pseudepiphallic sclerite broadly triangular, slightly concave, without arms; lophi big and membranous, separated by a roughly triangular, small indentation and covered with setae apically. Pseudepiphallic plate inconspicuous between lophi; posterior margin convex. Pseudepiphallic parameres spindly, more or less concave on inner side. Rami connected to pseudepiphallic sclerite. Ectophallic fold unobtrusive, visible just below the lophi, regularly narrowed toward apex, reaching posterior margin of pseudepiphallic parameres; ectophallic apodemes thick. Ventral valves united as one membranous lobe. Endophallic sclerite evident, more or less V-shaped. No dorsal cavity ( Fig. 8 View FIG B-D).

Female

Similar to male ( Fig. 9A View FIG ). Ovipositor. Dorsal valvulae apically blunt, armed with projections on the apical margin and an irregularly elevated surface. Ventral valvulae blunt at the end, apical margin depressed inwards ( Fig. 9B, C View FIG ).

Female genitalia. Copulatory papilla longer than wide, funnel-shaped, with ventral aperture; posterior margin rounded in dorsal and ventral views, acuminated in lateral view ( Fig. 9 View FIG D-F).

Coloration. Body dark brown. Head dark brown; clypeus and labrum dark brown. Pronotum brown. Legs yellowish brown. Slight darkening around crossveins in distal half of forewings. Darkened bases of spines of hind tibiae. Small darkish spots near spines ( Fig. 2C, D View FIG ).
