Gromenko".   Comparisons.  P. cruralisis distinguishable from the other four species in this species group by the combination of: elytra sutural angles shortly pointed, forming short denticles; outer apical angles almost rounded; elytra without black patch; tibiae black.  P. cruralisis very similar to  P. mellea, but only different in tibiae black and elytra disc depressions absent or much shallower than in  P. mellea.   Description. Body length 9.4–11.2 mm. Dorsum pale yellow; antennomere 1 yellow, remaining ten antennomeres black; apices of mandibles black; terminal labial palpomere black, terminal and penultimate maxillary palpomeres black; tarsomeres black; tibiae black, middle portion dark brown; venter pale yellow. Pronotum strongly transverse, PW/PL = 1.63–1.70; much wider than head, PW/HW = 1.10–1.19; widest at anterior third, lateral explanations very wide. Elytra without microsculpture; striae not incised, replaced by rows of very fine punctures; intervals completely flat, with punctures sparser than in striae; disc not depressed or very shallowly depressed near middle of intervals 3 to 6; apical truncation distinct, straight or slightly rounded; outer apical angles almost rounded, not forming distinct angles; sutural angles slightly pointed, forming short denticles. Apex of abdominal sternite VII very weakly projected at middle in females ( Fig. 8D). Gonocoxite II of ovipositor dichotomous, inner branch with two ensiform setae apically, outer branch with two or three ensiform setae apically. Male unknown.   Distribution( Map 4, magenta). West Java and north Borneo.  Geographical variation. Specimens from Borneo are somewhat different from the holotypefrom Java. They are much larger (ca. 11 mmvs 9.6 mm) and elytra disc with very shallow depressions in the middle of intervals 3 to 6 (without depression in the holotype). Based on their similar leg color, we determine them all as  P. cruralis.   Remarks.  P. cruraliswas originally described as a variety of  P. testacea, and recently ( Lorenz, 2005) treated as a subspecific name under  P. testacea. However, after the examination of the holotype, we found that  P. cruralisis closer to  P. melleathan to  P. testaceafor the similarities in elytra apices and interval punctures. The taxonomic position of  P. cruralisis still doubtful because the male is unknown. We treat  P. cruralisas a separate species for now because it is markedly different from other species in coloration. 4115871503 2016-05-01 Boreno 1182 5.443 Keningau district 7 116.4512 Sahah 42 43 1 1 4115871567 [151,1004,1684,1711] N.
