She is the first author’ s mother and has provided a lifetime of support and encouragement. Diagnosis. This species can be distinguished from the other species of the baiknami speciesgroup by the following combination of characters: smaller body, length 2.4–2.7 mm ; male head bluntly triangular, widest across eyes, ventral surface of head with pair of short carinae on temple; male mid-femur weakly depressed at base; midtibia bent; shape of antennomeres and genitalia unique to species. Description of Male. Length 2.4–2.7 mm . Body brown, antenna, elytra, legs, and maxillary palpi paler ( Fig. 15f ). Head: As long as wide, widest across eyes ( Fig. 15f ), ventral surface with pair of short carinae on temple. Antennomere 1 approximately 2 times longer than wide, 2 longer than wide, 3 subquadrate, 4–7 longer than wide, 8–10 subquadrate. Frontal sulcus deep and reaching midpoint of eye from frontal rostral lobes. Anterior frontal fovea round. Posterior frontal fovea oval. Eye large and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 15f ). Meso- and metathorax trapezoidal, longer than wide. Male mid-femur weakly depressed at base.
