Fastigium of vertex short, deeply sulcate; lateral margins bordered by low carinulae reaching apical 1/6 of compound eyes.

Hind femora moderately stout, 4.1–4.3 times as long as their maximal width; dorso-median carina slightly serrated, terminating in a small tooth; ventral genicular lobes obtuse (Fig. 2). Hind tibiae with 8 outer and 9 inner dorsal spines; outer apical dorsal spine absent. Hind tarsi short, not longer than the half of hind tibiae; third segment (without claws) as long as two others together; arolium large, almost reaching apex of claws. Tympanum large, oval. 10th tergite without furculae on posterior margin. Supra-anal plate triangular, 1.2 times as long as its width near base, with narrowly rounded apex; median sulcus deep, reaching apex of plate (Fig. 10). Cerci conical, 2.1 times as long as their width near base. Subgenital plate short, curved up, apex narrowed, rounded (Fig. 9). Epiphallus bridge-like, undivided; ancorae short; lophi of epiphallus lobe-like; oval sclerite absent (Fig. 14). Valves of cingulum narrow, strongly sclerotized apically; apical valves of penis very long and distinctly curved up; basal valves of penis connected with apical ones by flexure; rami of cingulum narrow, curved; posterior margin of zygoma straight; apodemes broad (Figs. 12, 13). Based on the colored images of other species of Alectorolophus (Eades et al., 2016), this species is likely to have bright coloration, but it was affected by alcohol preservation and the present of black and light patterns only is given below. Body light brown with black marks (Figs 1, 2). Dorsal side of head black, except light brown fastigium of vertex; genae black with light brown stripe along lower margin; face light brown with black stripes below the base of antennae; mandibles black (Fig. 3). Antennae light brown. Pronotum black with narrow light stripe along anterior margin of prozona, anterior and lower margins of lateral lobes; posterior margin of lateral lobes with broad light stripe; metazona completely light. Tegmina black, without stripes or spots; hind wings black. Fore and mid legs light brown. Hind femur light brown, without any dark marks; dorsal genicular lobes blackish brown, ventral genicular lobes light brown. Hind tibia light brown; dorsal spines with black apex. Abdomen dorsally light brown with a few small dark spots; 10th tergite and anal plate blackish; cerci light brown. Ventrally 1–8th sternites light brown with transverse blackish stripes along posterior margins; 9th sternite and subgenital plate blackish brown. Female. Similar to male, but larger and more robust (Figs. 4, 5). Head as in male, but vertex between eyes 1.4– 1.5 times narrower than width of frontal ridge between antennae, and vertical diameter of eye 1.7–1.8 times as long as subocular furrow. Antennae 25-segmented, reaching the base of hind femora; mid segments of antennae 3.2–3.8 times as long as wide. Pronotum as in male, but prozona 1.6–1.8 times as long as metazona (Fig. 4). Prosternal spine and mesosternal lobes as in male; metasternal lobes distinctly separated. Tegmina touching each other in rest position (Fig. 4), reaching posterior margin of 4th tergites, with rounded apex; radial area with irregular veinlets. Hind wings shorter than tegmina. Hind femora 4.0–4.3 times as long as their maximal width; dorso-median carina slightly serrated, terminating in a small tooth; ventral genicular lobes obtuse (Fig. 5). Hind tibiae with 7–8 outer and 9 inner dorsal spines; outer apical dorsal spine absent. Hind tarsi as in male. Tympanum large, oval. Supra-anal plate narrowly triangular, 1.4–1.5 times as long as its width near the base; median sulcus in basal half deep, in apical part shallow. Cerci conical, 2.0 times as long as their width near base. Subgenital plate 1.4–1.5 times as long as wide, with triangle pointed apex (Fig. 11). Basivalvular plates long. Ovipositor short, upper margin of dorsal valves and lower margin of ventral valves excised (Fig. 5). Body (after alcohol preservation) brown with black and light brown marks (Figs 4, 5). Dorsal side of head black, except light brown fastigium of vertex; genae black with light brown spots; face and mandibles black with light brown marks (Fig. 6). Antennae light brown. Pronotum light brown with narrow dark brown stripe along the median carina; metazona completely dark brown (Fig. 4); lateral lobes with large dark brown or blackish central spot (Fig. 5). Tegmina blackish brown, without stripes or spots; hind wings blackish. Fore and mid legs light brown. Hind femur light brown; dorsal side with three brown spots situated at the base, near the middle and in apical part of femur; ventral side of femur dark brown; dorsal genicular lobes blackish brown, ventral genicular lobes brown. Hind tibia light brown; dorsal spines with black apex. Abdomen dorsally brown with numerous dark marks; anal plate, cerci and sternites colored as in male; subgenital plate blackish brown. Ovipositor brown. Measurements (mm). Length of body: male 16.9–17.2, female 25.0–25.9; antenna: male 13.5, female 14.0; pronotum: male 4.7–4.8, female 7.2–8.4; tegmen: male 5.2–5.5, female 8.2–9.1; hind femur: male 11.1–11.2, female 15.0–16.1; ovipositor 3.2–3.5. Distribution. Endemic to Sulawesi Island (province Sulawesi Tengah). Diagnosis. The difference of a new species from congeners is given below in the keys for males and females. Etymology. The name of the new species is derived from Latin ‘im-punctus’ (without spots).
